Induced Myopia

Post to This Thread

im 20 years old and slightly farsighted +1 in each eye is there any chance of inducing axial myopia?.

OopsI 29 Mar 2017, 12:49


I did get an email, yes. Also on the website it said they will be shipped directly from Hong Kong to Europe, which is probably why the shipping time isn't much longer than it is when they are shipped to the US.

I'm really excited. Today I walked outside when it was dark already and discovered something interesting. There was A sign with a blue and a red word. Out of interest I took my glasses off to read it and was surprised to notice that the red word was pretty clear while the blue word wasn't readable at all. With glasses on it wasn't as much off a difference, I could read both words, the blue one wasn't as clear, though. Just thought I'd share that :D

So I know you're already counting the days for your glasses to arrive in the mail. When you placed your order Zenni should have sent you an confirmation number by e-mail saying that your order had been entered. Did you get that? By now your glasses should already be made and somewhere in the process of having the lenses checked for accuracy. Then they will be sent to their shipping department. They will be sent to California where your glasses will again have the lenses checked. Then they will be mailed to Austria and then to your mailbox. Give it another couple days and then you can that confirmation to track exactly where your glasses are.

Those frames are very nice, and -6.00 in 1.50 index should have some nice power rings, and cut in.

Very sexy!

Maxim 28 Mar 2017, 15:28

I should say, these -6.75 lenses can do no harm to Rebecca's eyes. It is true, that they could be too strong that her eyes would adapt to them. But it could be, that they don't accommodate these 3 diopters, but instead of that over the development of myopia a certain (myopic) astigmatism might develop from the tension these strong lenses produce in her eyes.

Soundmanpt 28 Mar 2017, 08:13


I don't think the difference between -6.00 and -6.75 is going to make any difference in adding any myopia. If you there hasn't been any change in your eyesight wearing your -3.75 glasses for well over 6 months then wearing even stronger glasses won't work. But I am concerned that you could cause serious damage to your eyes. If in fact there has been no change in your vision that will mean that you're going to forcing your eyes to focus through glasses that are 6 times stronger than they need. So I urge you to be extremely careful with wearing these glasses. I'm sure when you first got your -3.75 glasses and started wearing them you felt quite a bit of strain to your eyes and you're likely going to feel even more strain to your eyes. Just don't push your eyes too hard. It is a much better, and safer, plan to go up in small steps not big jumps. So I suggest that you test your new glasses in private by only wearing them for short periods to see how your eyes react. You can always place an order for glasses about -4.75 and hold onto your -6.75 glasses for down the road a bit.

Rebecca 27 Mar 2017, 21:09


I ordered -6.75, opting for increased potential myopia over lens thickness. I really like the idea of going up 3 diopters. They will arrive in 2 weeks; I'm very excited. Thank you for the valuable information on spring hinges; I think you are right that they will be good on this frame.

Soundmanpt 27 Mar 2017, 20:15


The -6.00 lenses will be thicker than using the 1.50 lens option than -6.75 would be with the 1.57 lens option.

The glasses you have selected should look very nice on you. I always think having adjustable nose pads are much more comfortable sitting on your nose because they are moveable. The answer to your question about spring hinges opposed to non spring really depends on how the glasses fit to start with. I see that these glasses aren't very wide, only 132mm. If the frame is too wide to start with then the spring hinges aren't much help in keeping your glasses in place like you want. But I think this frame is small enough that they should fit you very well to start with and that will make the spring hinges work the way they should in keeping your glasses in place. Also I like the idea that you are getting an all metal frame. That should make your glasses feel nice and sturdy. If there is any downside sometimes the paint on metal frames tend to chip off after sometime. But I have a feeling you will probably be considering new glasses within a year anyway so that shouldn't be a problem for you.

oopsI 27 Mar 2017, 14:10


I know I'll (probably) eventually need them to see, that's what I'm trying to accomplish. I've tested this out a good bit and I'm certain I want this (I wanted it for the past 8 years).

Thank you for your concern, though.

Rebecca 27 Mar 2017, 13:57

I think I will have to get -6 because anything higher than that is only available in 1.57 lenses. Which would be thicker, -6 in 1.50 or -6.75 in 1.57? The first one, right?

Here are the frames I have chosen:

Are spring hinges looser than normal hinges? I have normal hinges right now and they are nice and tight. I don't want them to be loose.

abtonio 27 Mar 2017, 13:41


I guess if you wear one of these for longer periods of time

you will really start to need them to read far,

how do you feel about that ?

best regards, antonio

oopsI 27 Mar 2017, 13:33


thank you.

I think 0.75 is enough and I'm hoping it's not too much and I'll end up not being able to wear them, but I think I'll be okay. I can see clear up to 10 cm from my face and working on the computer for hours straight's not a problem (no headaches, I do get dry feeling eyes sometimes) , so I guess my accommodation's still good enough to handle the increase.

I'm worried about customs here, because if I'm unlucky I have to pay import duty (Which isn't that much money, but it's annoying, because I'll have to go and pick the glasses up at customs.

antonio 27 Mar 2017, 13:30

OopsI, no I´m not sure,

seems okay to me your step,

but on the whole that´s so much more than you need now,

I can´t yet imagine you in them :-)

keep us informed how you feel in your new HD world to come :)

or discuss with us on

especially your 2 stronger ones have really nice frames - I like your style 8-)

best regards,


Soundmanpt 27 Mar 2017, 13:19


I really like all 3 that you ordered and I think that you will love them as soon as you open the package and see them. You seem very determined and that is what you need to be if you want to induce myopia. I tend to agree with you that you may not be wearing the -1.00 glasses all that long before you're ready for the -1.75 glasses. I think going with increases of -.75 is enough of a push to your eyes.

I know you're looking forward to getting your glasses so you can get started wearing them so of course you don't want them to held up in customs. But it doesn't happen very often and when it does Zenni must get notified because they will quickly remake your complete order at no charge to you and it will be resent within a couple days. So the delay may only be a few days and the bonus is you end up an extra set of glasses. In my 12 years of ordering from Zenni it only happened to me once and delay was only like 2 days longer. But as luck would have it I have a very good friend that manages a Sam's Club Warehouse Optical Center. I would visit with her about once a month and I knew she wore glasses fro driving. So every visit to see her I would bring in 3 or 4 pairs of Zenni glasses to show her. Sam's Club doesn't give their employees glasses free. They only get a 10% discount. Anyway after doing that a few times one day when i went in to see her she quickly told me that she didn't want to see any more glasses from me. She told me that she had ordered 3 pairs and was currently waiting for them to arrive. She was a little concerned because it was a couple days past the 2 weeks they promise. I told her what likely happened and assured her there was nothing to worry about. I called her 2 days later just to see if she had heard anything about her glasses and she said they came in the following day of my visit. She said she really liked them and had already wore one pair driving to work. So of course the next day she got her 2nd order so she ended up with 2 of each that she ordered. She told me that a worker in the store really liked one of her new glasses so she gave her the glasses and put that girls prescription into the frame. I'm sure that you much rather have you glasses arrive early and only get the one set rather than taking a little longer and getting 2 sets.

oopsI 27 Mar 2017, 13:13


First and foremost thank you, I do love the two more "expensive" frames

what do you mean? Do you think the steps I increased the prescription in are too large?

oopsI 27 Mar 2017, 13:10

Also before ordering from Zenni's today I decided to test if I actually want this one more time, by walking around outside in the +1.5 glasses. It's odd, I do seem to react strongly to my minor astigmatism, because I (subjectively) see worse in them than I do with the +2.5 over my actual prescription. The ghost image seems more prominent with a higher spheric prescription, too.

I quite enjoyed it, though. I felt a little nauseous after some time, but I think that's because the change occurred so sudden and it wouldn't be like that if my prescription was to go up slowly.

antonio 27 Mar 2017, 13:04

hi OopsI,

increasingly nice glasses,

but aren´t those increasingly a little strong for you ? :-)

best regards, antonio

oopsI 27 Mar 2017, 12:29


Sorry, I didn't see the questions you asked.

I ended up with three pairs, because I couldn't decided what to get and I found a promo code that gave me ten percent off, so one pair was actually free as well as me being a little worried that my orders will be held by customs which would mean it I'd have to wait quite some time for that.

I ended up with those

(Prescription (sphere) -1, no AR as I'm hoping that I don't have to wear that pair for long I thought I could go cheep here. I like them enough to wear them full time if needed, though)

(Prescription -1.75 +AR. I know you said I shouldn't do that, but again, I couldn't decided if I wanted this or the next pair and ordering the same Prescription seemed silly, this felt like the right thing to do, so I went with my guts. If I never end up wearing those I still really like the frame, so I'd probably have my optician put in my prescription in, once it's stable. )

(Prescription -2.5 , AR and additional clip on shades.)

The last two were the ones I've been always getting back to, so I thought I should get those.

oopsI 27 Mar 2017, 12:17


okay, thank you :) I placed the order, I really hope this isn't going to take long, I'm really excited!

Soundmanpt 27 Mar 2017, 12:03


So based on your question it seems like you're about to place your order for glasses? I'm sure this is exciting for you. Be sure to let me know which glasses you order and the prescriptions you decided to get for them. Now you will be watching the clock as well as you're e-mails. You know that you can track exactly where your glasses are if you want.

Soundmanpt 27 Mar 2017, 12:00


You did good in dodging that one, because I thought that your mom had to notice that your glasses looked a lot stronger than your other glasses looked. Mom's tend to notice things even when you don't think they do. But it will be much harder to convince her if you do go to -6.75. Your lenses would be nearly twice as thick as they are now. For that reason you really need to hold off ordering anything until you get your eyes examined. Then if still are determined to go that strong you can simply tell your mom that your eyes got a lot worse since your last eye exam and that your glasses are going to be a good deal stronger than your current ones. I asked you about what type of work you are doing hoping that maybe it was an office job and you could blame your job for ruining your eyesight.

Soundmanpt 27 Mar 2017, 11:48


Trust me you can ignore that. That has been on there for some time now. I remember the first time I saw that and i was a little concerned like you are. Place your order it will be fine.

oopsI 27 Mar 2017, 11:06

Hey, I'm a little concerned with the Terms and conditions from Zenni's. It says they require a copy of my prescription, do they actually need that?

Rebecca 27 Mar 2017, 10:35

Yes, she noticed the thickness, but I said it was just the way these lenses were made due to being low index. I work at Value Village in Vancouver, BC. I will be quitting when I turn 18 on June 7 so I can get the maximum welfare amount.

Soundmanpt 27 Mar 2017, 10:29


So what you're saying is that of course you want your eyes to change but you also like the looks of wearing stronger glasses. And you want to enjoy the reactions when someone tries your glasses on and they will think that you can't see anything without your glasses. But even now with your current glasses i'm sure they can't see much of anything through your glasses now. So you have to enjoy it when someone tries your glasses and they comment on how strong your glasses are and how bad your eyesight must be. Of course you go right along by saying that you can't really see anything without your glasses. From the pictures you posted of yourself wearing your glasses they clearly show a nice bit of cut-in and i'm sure that your eyes are noticeably smaller looking at you through your lenses. When you got your current glasses I assumed that you used your mom's credit card then to too? Didn't she notice how strong your glasses suddenly got from what they were before? What type of part time job do you have?

Rebecca 27 Mar 2017, 09:41


Yes, it's mostly about the look and thickness of the lenses. I want everyone to see my strong prescription. And when they try them on, they will think I'm really blind without them. Even the thought of it gives me such a buzz.

I can always get more glasses after my eye exam. I have a part time job so my mom will let me use her credit card online.

Soundmanpt 27 Mar 2017, 09:33


Before you order any new glasses I suggest that you at least wait until you get your eyes examined and see if there has been any change in your vision since your last eye exam. I'm sure you understand that even though you're wearing -3.75 glasses when you take your glasses off for the first few minutes your eyes are going to be seeing the way someone would that needs -3.75 glasses. But then your eyes start to regress and your vision is soon much better. But not perfect because you do have an actual prescription. For that reason it has to very hard for you to determine if your eyes are returning to what your natural vision is without glasses or if it is somewhat worse and you just don't realize it.

Taking big increases is very hard on your eyes and this can cause retinas to detach. When your -3.75 glasses arrived and you put them on for the first time didn't they feel very strong to your eyes? Those first few days wearing them your eyes must have felt like they were being pulled out of your head. Your eyes were likely bloodshot from the strain of trying to focus with them on and reading couldn't have been very easy or comfortable to you. You did very good just by pushing through it until your eyes slowly adjusted to your glasses. Honestly if there isn't any change after wearing your glasses this long then going up another -3.00 isn't going to change anything either. Now if you just want your glasses to look a little stronger that's fine, but you really need to be careful.

Rebecca 27 Mar 2017, 09:05

Sorry, that was me. Not intended to be anonymous.

 27 Mar 2017, 09:04


Thank you very much for the well wishes; I wish you the same.


Unfortunately, you may be right. But my eyes do accommodate better than they used to. Wearing -3.75 is no problem at all.

I am thinking about going up to -6.75.

NJ 27 Mar 2017, 08:36

Rebecca, I would respectfully submit that there's no evidence that wearing minus glasses above one's natural prescription will induce any additional myopia in those not otherwise predisposed. It's essentially the same as doing a lot of close work, like most young people do in school. And even among those who are predisposed, all the evidence suggests that reducing the accommodative demands of close work have only very modest effects on reducing progression; so modest in fact that there's no widespread consensus in the optometry community about prescribing bifocals to children who have early myopia, despite the considerable risks that accompany more severe myopia.

Just keep in mind that this is a fetish/fantasy website, and the needs and desires of the participants, including myself, often color the beliefs and claims that appear on this forum.

You're more than welcome to keep trying, though. I sure did in the past!

NNVisitor 27 Mar 2017, 08:22


Factoring in my astigmatism probably near 11.50. I did not have a retinal detachment. My vitrious pulled away from my retina in one area. An opthalmologist has found some scarring on my retinas. It can mean many things so I don't worry but I am concerned.

I've had opthalmic migraines and I know the flashing colour pattern is not a retinal detatachment. What to watch out for is flashes of light when going from a dark room to a lighted room or the opposite. Or flashes that look like a fluresant light flickering. Or a curtain type covering in one eye. Abdolutely head to a hospital emergency room for any of these three.

I'm amazed at how you can tolerate a higher prescription. 20/10 is fantastic visual accuity. I've had trouble tolerating prescription increases which I felt were too strong. I really didn't wear my glasses all the time when I was growing up so that could be why I had adjustment problems. My eyesight got worse and worse. Yours may be stable as stronger lenses are not worsening your myopia. I think genetics play a strong role in myopia progression and that you will not become more myopic or at the most slightly more so. Best of luck to you going forward. You are still young and living at an exciting time of technological, scientific and medical advances. I wish you a great future filled with happiness.

Rebecca 26 Mar 2017, 20:26

Sorry to hear about your retinal detachment. What is your Rx?

I have been stacking glasses to get an idea of what I can tolerate. I can see fine with -5.50 so I'm thinking about increasing by 3 diopters to -6.75.

NNVisitor 26 Mar 2017, 16:03


The higher the myopia the greater the risk. It doesn't mean it will happen but who wants a heightened risk?

I've had retinal problems that had to be fixed. The last time it was 10 minutes of laser treatment. I will have to get my retina's checked again. Sure I am concerned. It's important to learn the signs. A pending retinal detachment is an absolute emergency.

Rebecca 26 Mar 2017, 11:41


How likely is retinal detachment? Does the chance increase with more diopters? I at least want to do -5. Or is that too high? How is retinal detachment treated?

Soundmanpt 26 Mar 2017, 11:16


That's amazing that they are still able to return to your natural vision so quickly after wearing glasses that strong. Now i'm sure that you're aware that even by wearing -3.75 glasses at most your eyes were likely only going to change to around -2.00. So are you quite certain that there has been no change in your vision in the past year? Maybe wait until you get your eyes examined and find out what prescription you get this time without any type of cheating to alter anything. As far as any suggestion for ordering stronger glasses it is very hard to say how much more over correction your eyes can tolerate. The glasses that your currently wearing is much stronger than I would have ever recommended to you last April. Do you remember how long it took for your eyes to adjust to your glasses back then? I really wouldn't expect that going any stronger is going to have any effect on your eyes as far as making them anymore myopic than they are now. You just want to be careful not to go too strong and cause your retinas to detach. From what you have said it sounds like your eyes are very comfortable wearing your current glasses and needless to say you are able to see incredibly well with your glasses. But I wouldn't try and push them too hard by going overly strong again. Maybe order your new glasses with -4.75 lenses. I know you are wanting better results than you so far haven't seemed to get as far as actually needing stronger glasses based on written prescription. But at least your eyes aren't so stubborn not to allow you to wear fairly strong glasses. And while your wearing your glasses your eyes are happy to be relaxing with the help from your glasses.

Rebecca 26 Mar 2017, 09:06


It's just a few minutes. What would you recommend for my next prescription? How much do you reckon my eyes can tolerate? I remember someone a long time ago recommend going up 3 diopters each time, so that would be in the -6 range which is my goal.

Soundmanpt 26 Mar 2017, 08:56


Well if you have been wearing your glasses constantly for the past 6 months like you say that you have then I have to agree wit you that you have very stubborn eyes and they are refusing to be changed for some reason. You're certainly still young enough for you eyes to be changed and your glasses are more than strong enough for your eyes. In fact I would have suggested you go much weaker for your glasses, but your eyes don't seem to have any problems with seeing with your glasses since your able to see 20/10 wearing them and you probably are seeing even better than that. So there is no doubt that your eyes have adjusted to your glasses which is why if you take your glasses off during the day everything should be a blurry mess to you. Once you have your glasses off how long does it take before your natural eyesight returns to you? Is it only a few minutes or more than an hour. If you're hoping to see at least some change in your eyes I would suggest that you try and get a late afternoon eye appointment and not an early morning exam. Your eyes should at least me much more stressed later in the day.

Rebecca 26 Mar 2017, 08:03


For the past 6 months I really have worn them constantly, from when I wake up to when I go to sleep. I only take them off in the shower. So I don't know why my eyes are so stubborn. :(

Soundmanpt 26 Mar 2017, 07:36


Your response wasn't what I was hoping and expecting to hear. Your vision when you awaken should be considerably worse by now after having wore your -3.75 glasses for nearly a full year. You;re certainly still young enough for your eyes to be changed and the glasses you're wearing are more than strong enough as well. So it makes me question how much you wear your glasses? Being the right age and wearing the right glasses are both important but it is also critical that you wear your glasses constantly from the first minute you open your eyes each day until you go back to bed at the end of the day. Wearing your glasses for 15 hours a day and then having them off for an hour is the same as not wearing glasses at all. You have have done nothing to induce doing that. I'm not sure what trying to fool the machine or doctor would prove to you? You know of course that the whole process from the time you enter the doctor's office until you leave can take slightly over an hour. I don't know how long your vision stays blurry after you take your glasses off but if starts returning to normal during your exam that could lead to some interesting questions from the doctor if your vision is slowly returning during the exam. Fooling the doctor or the machine isn't going to prove anything for you. You want to know if there has been any real change in your vision in the past year. You can only find that answer by not cheating for the exam. Ordering stronger glasses isn't going to change anything that your current -3.75 glasses shouldn't have already done to your eyes. I think that you do probably wear your glasses quite often but you take them off to give your eyes a break too much.

oopsI 26 Mar 2017, 02:13

Thank you Cactus! Glad to hear your retina's doing good.

Rebecca 25 Mar 2017, 22:36


Unfortunately, my natural vision is quite good when I wake up. It's only really bad right after I take off my glasses. So for the eye exam, I'll wear my strong glasses as much as possible and then switch to my prescribed glasses at the last minute. I hope that will work to fool the machine.

Soundmanpt 25 Mar 2017, 21:40

Cactus Jack

I know I can always count on you to provide a much better and more accurate explanation than I can.

I was diagnosed with type 2 diabetes about 7 years ago. I honestly don't watch my diet very well at all. At first I was told to check my blood sugar 3 times a day but since then I am checking and reporting my numbers at my 6 month doctor visits. It ranges between 118 and 138 mostly but every so often it spikes up to around 165 or so.

Glad to hear that your exam seemed to go well. I actually have to see my endocrinologist on march 28th. My 6 month checkup. He always asks about my eyes and I am telling him the truth that so far i don't notice any change in my eyesight.

Cactus Jack 25 Mar 2017, 21:25

Soundmanpt and oopsI,

Night Blindness can have many causes. Some relate to Retinal problems, Glaucoma, clouding of the Crystalline Lens by Cataracts, and Insufficient Rhodopsin (or “Visual Purple”) that is necessary for the Rods to do their job.. A more subtile cause is simple uncorrected Myopia.

At night or in low light conditions, you have two things working against you if you are Myopic. The first has to do with the characteristics of complex lens systems. The eye’s lens system is very similar to a high end camera lens. It has multiple lenses and an Iris (pupil) that can be adjusted for the lighting conditions. The Iris is “closed down” (higher “f” stops) and the pupil contracts to let in less light, so the film, image sensor, or Retina is not over exposed to light. This has a secondary benefit, It increases the Depth of Field or the Range of useful focus of the image. If the Iris or pupil opening is small enough, even blurry images can get pretty clear. That is why people often squint to improve their vision or ECPs us a pinhole “lens” to see if correction is even possible.

The second thing is that if looking at a dim light source (a star in the sky is a good example) there are a limited number of Photons arriving from the distant source. If they are NOT in good focus, the few Photons are spread over several Rods in the Retina and their may not be enough Photons to trigger a response so no signal is delivered to the Visual Cortex and you can’t “see” the star. If the image is not sharply focused, you may also see a halo or similar effect around a brighter light source because there are more Photons. If they are not properly focused and are diffuse, they can activate nearby Rods that should NOT have been activated and you see a halo or starburst of light around the actual source.

BTW, I had a Retinal exam yesterday where my eyes were dilated and my Retinas checked for Diabetic damage with a very bright light and a High PLUS magnifying lens. With my eyes dilated, I had no defense against the bright light and it was pretty rough. Fortunately, no Retinal damage was found. No change from previous exams (I watch my Blood Glucose levels like a hawk), but the bright light temporarily bleached out the Visual Purple in the Rods of my Retina. It took several minutes, while the Visual Purple regenerated andI could see well in the dim exam room. I have fairly frequent (every 6 months) Retinal checks and I knew what to expect.

A little bit of extra MINUS, over correction or a bit of PLUS under correction can sometimes help significantly with Night Vision issues, as it did with the friend who was having trouble driving at night


Soundmanpt 25 Mar 2017, 21:25


When your -3.75 glasses arrived and you put them on for the first time didn't they feel much too strong for your eyes? Would I be correct to assume that everything looked extremely intense and mall but very clear and sharp? But very difficult to see anything close up with them on. How long did it take before your glasses began to feel normal to you? I am not at all surprised that now with your glasses you have no problem at all seeing the 20/10 line on an eyechart and much worse without your glasses. That would be about what I would expect when you first take off your glasses. But what you really want to know is if your eyesight is really that poor. Almost certainly your eyesight is worse now than it was before you started wearing your current glasses. How much of your natural eyesight returns to you after you have your glasses off for a while is the only way to really know. If your curious to know try testing your eyes in the morning before you put your glasses on. You had a slight prescription before but lie you said it was mainly astigmatisms. But just by looking at things from a window in your house should give you some idea of how much you need your glasses now.

Rebecca 25 Mar 2017, 12:38


Thank you. Yes, I wore them full time. I had a vision test (trying to read the letters) but not an eye exam. I got 20/10 vision with glasses on and did poorly with them off.

Here is a picture for proof of who I am:

oopsI 25 Mar 2017, 11:17


From what I've gathered night blindness is actually a different condition that cannot be corrected with glasses (the rod's are not working properly). Here needing a higher prescription at night is called nighttime myopia (might not be the term in English, though). It is caused by the pupils being wider at night.

oopsI 25 Mar 2017, 11:04


thank you a lot for your concern, I'm happy that people care enough to mention it in this kind of forum. But I really doubt that what I'm doing will do any damage to my eyes, that cannot be corrected by glasses/ other vision aid's. In most of the surgical jobs you work with some kind of magnification method anyway, which is usually just adaptable to a prescription (I'm certain I don't want to do any kind of orthopedic surgery where you don't do that) and most doctors I know are myopic (at least some of them are at about -6D) and I have never heard from anyone that they had a problem with patients.

Also again, I'm going to check on the progress regularly and if I notice all of this working too well I'll stop immediately. My plan right now is to go through with what I've discussed here on the forum and then go for an eye exam in October (not wearing the glasses before that for a day or two to see my real prescription) and if my prescription was any higher than sph -1.25 I'd stop wearing too high of a prescription.

Why am I not surprised to hear that you already are holding reading material close to your eyes? Like I said before, you clearly have done your research on inducing myopia haven't you? And yes I think your new glasses will improve your night vision. You might have the same problem others have with driving at night. Funny thing if yo had mentioned that at your last eye exam I think you might have even gotten a slightly stronger prescription for your glasses. It's called "night blindness" or at least that is what I have been told doctors refer to it being. A really good example is my best friend's wife. About 5 years ago we were all together heading home for a ballgame and we were in my friends car. My friend had been drinking so he asked his wife to drive because she doesn't drink. It was quite dark and she was complaining about not being able to see very well. i could see that she was squinting quite a bit. I asked her if he had the same problem during the day and she said she didn't. that she could see just fine. I told her that she should get her eyes examined and to be sure to tell the doctor about the night driving problem based on what I had heard. About 2 weeks later I was at their house talking to her husband and she heard me and she came out wearing glasses. She thanked me and said that she took my advice to get her eyes examined and she made a big point about the driving after dark thing. It was a good thing because her vision checked out as being perfect. But because of the night problem the doctor wrote her a prescription fr glasses. She asked for a copy so she would be able to tell people why she needs glasses. She showed it to me and it was only -.50 SPH for both eyes with a good quality AR coating (anti-reflective). And it was written on the slip Must be worn at night for driving. She said that she had already tried them out and they made a big difference for her.

I am not surprised to hear that you're considering optometry I really thinkyou would be very good at that because you clearly have an interest in it.

Soundmanpt 25 Mar 2017, 09:24


Actually if you look back to her comment on "17 Mar 17:08" she said that she likes the looks of glasses that are -2.00 to -6.00. But right below that she says that her goal is -2.00. You're likely right that with so much reading and studying her actual eyesight would slowly change over the next 3 or 4 years. But by wearing stronger glasses she is going to reach her goal much faster and it is impossible to know if all the reading will surpass her goal prescription. I think the reading will mostly bridge the gap between her actual eyesight and the glasses she will be wearing, not exceed it. She seems to be a very intelligent young lady and I think she will know when she is happy with where her eyes are at. She may decide to stop before she gets to -2.00 or go a bit beyond that point. Just because she'll be wearing glasses shouldn't in any way mean that if she won't be a very good surgeon. And I seriously doubt that there would be any patient confidence lost because she's wearing glasses.

I assume Julie is still waiting for her glasses to arrive? looking back it appears she placed the order with the help of you and Cheryl back on the 18th so that is only about a week ago. She was getting bifocals and I know Zenni says that can sometimes delay them a few days.

Likelenses 24 Mar 2017, 18:15


Really hot looking in these glasses. Nice cut in.

Did you wear them full time while in prison?

Were you able to have your eyes examined while in there?

Likelenses 24 Mar 2017, 16:47


You stated that ideally you would like to reach -3.5.

Have you considered the fact that by the time you finish med school, which in itself will do a number on your eyes,combined with inducing that you may wind up very myopic.

So much so that your vision may not be very good for performing surgery.Or depending on your specialty,a loss of patient confidence in you due to your thick glasses,and perception that you do not see very well.

I think that would be a real oops!

oopsI 24 Mar 2017, 11:20

I do my best to do that, already, yes and I hope they'll arrive as soon as possible (also I want to know if I see better in the -1.00 ones than in the glasses I have right now, especially at night, because i feel like I don't see as clearly at night as I should)

And again, I don't know if there will be any changes in my vision by the time we do that eye test, but I think it's a good interval to check if I've actually made any progress. I'll have to find out if they ask for my prescription, though, because that could be awkward, lol.

I am thinking about going into ophtalmology for sure. I remember watching videos on manual refraction years ago. I love the physiology of the eye, too.

Soundmanpt 24 Mar 2017, 08:55


I know you're in med school, are you intending on becoming a doctor? With your interest in vision have you considered becoming an optometrists? I really think you would be very good at that and you certainly have a head start in that field already.

Soundmanpt 24 Mar 2017, 08:52


So really by the time you do the eye test in med school you will have only had your glasses about 2 months or so. That may or may not be enough time to show any progress. But even now while you're wearing your actual prescription glasses try and remember when studying and reading to be in a dimly lighted area and hold whatever your reading as close to your eyes as possible as much as your eyes will allow you to. And continue to do that once you get your new glasses. I hoping that you get your glasses shipped faster than 3 weeks. I'm in the US and my recent orders have been arriving in about 9 - 10 days. But I have no idea what the delivery time is for Austria.

oopsI 23 Mar 2017, 12:26

Oh yes, I'm really excited. Especially because we will do a vision test in med school in about three months where I will actually be able to check the progress a little and I'm really looking forward to that to see if my vision will be worse by then (I know it might not be, though).

I really hope they will arrive in about three weeks. At that time I'll have to do a bunch of reading, too, which I expect to work in my favour.

Soundmanpt 23 Mar 2017, 12:19


Yes without a doubt getting a sunglasses clip for one of the glasses is a better idea than spending extra money on a pair of sunglasses for sure and the clip will fit the glasses you get perfectly. I'm just happy for you that you're going to able to order your glasses between now and Monday for sure. And I have a feeling you can't wait to get your glasses so you can get started wearing them.

oopsI 23 Mar 2017, 11:56

Yes Soundmanpt, that is true.

I didn't think I'd want the sunclip, but if you say it's good I'll just order it for one of the pairs (probably the -2.5 pair I can wear in the summer as I rarely read outside anyway so it makes sense to choose it for a stronger one) instead of extra sunglasses.

I still don't know if I want to go for a more expensive but pretty pair for the -1.00 glasses or if that would be a waste because I won't wear them for long, though.

Soundmanpt 23 Mar 2017, 11:41


Those are the decisions that only you can make. You know the size of glasses that will fit you best and you have an idea what prescriptions you want to start with. You know that all of the glasses come with an optional sunglass clip that is only like $4.00. I have ordered that for several people in the past and the clip is usually a perfect for the glasses.

oopsI 23 Mar 2017, 11:19

Hey :)

I have yet to order the glasses because I haven't got my money for next month yet. It will be there either tomorrow or on Monday so that will be the day I'll place the order on.

I'm really conflicted, because I can't decide on a frame so I'm debating if I should order two (+ a pair of sunglasses) pairs (but that would really only make sense if I ordered two different prescriptions).

I'm conflicted, lol.

Soundmanpt 23 Mar 2017, 10:43


Just curious if you placed your order for your glasses yet and which glasses you decided on as well? Back on the 18th you said that you planned on ordering your glasses this week.

Soundmanpt 22 Mar 2017, 10:55


Sorry to hear that you were in prison the past 6 months but good to hear that you're out now. It took several minutes of searching but I found that you first came into this thread back on April 18th 2016. You said that you had last gotten your eyes examined in June of 2014 and after a bit lying you managed to come away with a prescription of -1.00 for each eye and -.25 astigmatism in your left eye. You wore your glasses with this prescription constantly over the next 2 years with little or no change to your actual vision. But in April of 2016 you got your eyes examined again and and your results were Right eye -.75 -.50 / Left eye -.25 -.75 So a little bit of a change You were planning on ordering glasses on line with a much stronger prescription but at that time you did say exactly what that was going to be. But it seems that you took "Specs4evers" advice to order your glasses -3.00 stronger than you were prescribed. At the time you were only 16 so because of your young age he felt that your eyes would have very little trouble adjusting to the stronger glasses. Apparently he was right and your eyes were able to see pretty well with your -3.75 glasses. You have had your glasses for nearly a year now and in "Post your Prescription" you indicated that you are planning on getting your eyes examined again in April and you're hoping for an increase this time. If you wear your glasses constantly and with your young age I would be very surprised if you don't get a considerable increase from your last eyes exam. There is no harm in testing your eyes your self. I'm sure when you take your glasses off to clean them things are quite blurry, but the real test is how blurry are things when you wake up in the morning before you put your glasses on? It should much more blurry than it was before you started wearing your current glasses. Nice that you included several pictures of you wearing your glasses. They look really good on you and that style of glasses just happens to be a favorite with me on young women. I'm sure I don't have to remind you that you can't wear those glasses if you intend to go back to where you last got your eyes examined. You will have to wear the glasses that you were prescribed. I think Clearly is based in Canada which maybe why the total is less for glasses but I don't think Zenni charges too much more than $5.00 to ship to Canada. They are International and I know that even shipping to the UK was only $8.00. But they don't charge any extra for stronger prescriptions until you reach -8.00 or more. One way to find out is to call them. They have an 800 number and customer service is very good as well.

Welcome back and good luck at your upcoming eye exam.

Rebecca 22 Mar 2017, 00:04

Hi, I'm back. I was in prison for the past six months. I hope you haven't forgotten me because I certainly haven't forgotten this forum. Tomorrow when I get my new phone I will post pictures of me in my glasses with my name and timestamp. For now, here are some pictures of me with -3.75, the highest I could get from Clearly without paying for lenses.

Cactus Jack 20 Mar 2017, 16:49


It is possible that you may have a bit of Latent (Hidden) Hyperopia. That often happens to people with Hyperopia (corrected by PLUS glasses). It is actually the same thing as Pseudo Myopia except on the other side of 0.00.

Hyperopia is the ONLY refractive error that you can correct internally, using your Ciliary Muscles and Crystalline lenses. If you do that long enough, your Ciliary Muscles will have trouble relaxing.

It is nearly impossible to tell if a person has Latent Hyperopia until they start wearing PLUS glasses and it can take a while for it to be revealed. The symptoms are a need for more PLUS in their glasses within a few weeks or months of starting to wear PLUS glasses full time. Wearing PLUS glasses allows the Ciliary Muscles to relax and that reduces the amount of internal PLUS that needs to be supplied by the Crystalline Lenses. This can have a side benefit of making more Accommodation available for focusing close.

However, if Presbyopia is beginning to become problem, it can speed the requirement for bifocals or progressives. It is very easy to get Hyperopia and Presbyopia confused, both require PLUS correction. Hyperopia requires PLUS to correct distance vision and Presbyopia requires additional PLUS (an Add) to help you focus for reading or other close work.

The small amount of Cylinder and Axis correction will make things better at all distances, particularly for reading text.


glasses4me 20 Mar 2017, 13:59

Cactus Jack,

Thank you I age would be a barrier. Perhaps it's not a good idea.

I actually wish inducing hyperopia was possible. I have a small plus. I can still see distance while wearing them but I think this is only because it's a small add and they correct some small astigmatism.

OD .5 Cyl -.25 Axis 025,

OS .5 Cyl -.5 Axis 180.


Cactus Jack 19 Mar 2017, 07:18


There are actually two types of Myopia. Axial or True Myopia results when your eyeballs grow longer than they should for the total PLUS power of your eye's lens system. Axial Myopia is considered Permanent. Pseudo or False Myopia is caused by your Ciliary Muscles and Crystalline Lenses (your auto-focus system) having difficulty fully relaxing for distance. It is considered Temporary, but Temporary can be a rather long time if you wear glasses with more MINUS than you actually need.

Wearing more MINUS than you actually need can cause headaches, but if you have enough Accommodation available to compensate for the MINUS, the headaches will go away. The trick is to NOT be too aggressive. We typically suggest that you start with -1.00 over correction from your actual prescription and not increase that until those glasses get comfortable while reading. The first step is targeted at strengthening your Ciliary Muscles. In some ways it is like using weights to strengthen muscles. You DON'T start with heavy weights, you start with light weights and lots of repetitions. Too much MINUS or Too Heavy Weights are counter productive.

At 39 it is highly unlikely that you can Induce any Axial Myopia, your genes simply will not let that happen. You might be able to Induce a bit of Pseudo Myopia, but Presbyopia, which is the gradual stiffening of the Crystalline Lenses, will work against you. If you use up some of your diminishing Accommodation Amplitude compensating for too much MINUS, that will reduce the amount of Accommodation available for focusing close. That will lead to the need for bifocals or progressives before you need them without the excess MINUS.

Evening out your prescription is probably not possible.

It would be very helpful if you would post your complete prescription.


glasses4me 19 Mar 2017, 03:20


I hope you can help with a couple of questions.

If you wear stronger glasses to induce myopia is it permanent?

I guess you would get headaches at first - would this pass? Would it get to a point where it's just normal?

What happens when presbyopia sets in? Given I'm already 39.

I already had +.5 glasses. Could doing this just even out my eye sight?

Thanks Gary

antonio 18 Mar 2017, 17:06

yes med school is very long,

so you probably will develop pretty some

natural shortsightness like me :-)

ok, then I don´t worry, :-)

yes 15 cm clear in front of my eyes and that´s it :-),

increasingly blurrier farer away for me :-)

and pretty ridiculous to hold things that near to see,

don´t you think ? :-)

if you like to chat just visit

best regards, antonio

oopsI 18 Mar 2017, 16:59

Thank you antonio.

With your prescription it should be around 15 cm to see clearly, right?

I don't want to end up any higher than -3.5, I'd like something between -2 and -3 at most.

And yes, I went from +0.25 to -0.25 in 10 months (3 of which I was actually in university so I might very well be on the way of developing a little higher of a prescription naturally) and I'm going to make sure I'll go check the progression on my own regularly and go for an eye exam in a year, I think. If the development of axial myopia somehow seems to be going too fast I'll stop, don't worry about me ;)

antonio 18 Mar 2017, 16:48


to give you an idea what my prescription means in practical life:

I can hardly find my own glasses if my eyes are much more than 30 or 50 cms away from them.

So I tend to need glasses to find my glasses now, which is quite contradictional :-)

best regards, antonio

antonio 18 Mar 2017, 16:45

hi OopsI,

yes I guess med school might made you more shortsighted anyway, you said you already went from +0,25 to -0,25,

so that seems to happen anyway for you.

And if people have seen you wearing -2 for some time, that´s already normal to them to see you in those.

But please don´t exaggerate, take into account that your eyes can drift towards shortsightness on their own as they already seem to do and that way you could really get dependant on glasses to see as I´m now.

best regards, antonio

oopsI 18 Mar 2017, 16:21

Hey antonio,

before that they were at +0.25 with a -0.5 cylinder, so barely anything at all, but again, no drivers license without them. For some reason my left eye doesn't want to see properly without correction, but it's the better one when I do wear glasses.

And yes, I'm unworried about the change up to -2 or something, but if I do go higher observant people might notice. But then again, I remember in middle school a classmate of mine went from -1.00 to more than -5 within a year and nobody questioned it. I can blame it on med school, I guess, lol.

antonio 18 Mar 2017, 16:09


if you have worn glasses already for a year,

normally nearly nobody will ask you if your prescription goes up a little, as this is quite normal- happened to me too - and difficult to see anyway.

So don´t worry, nice you like being bespectacled, too

best regards, antonio

antonio 18 Mar 2017, 15:49

hi OopsI,

nice eyeglasses, you wear currently, OopsI,

by the way, if you updated a month ago your prescription,

what was it before your current cylindric lenses. i.e. how strong ?

I´m astonished you wear them already for a year always when being outside, but yes, if astigmatism makes the world wavy for you as you said, I can understand why you wear them so much,

best regards, antonio-o

oopsI 18 Mar 2017, 13:34

Thank you for the explanation :) If you say 130 is a good width then I won't worry about it. My glasses suit my face well (if I say so myself, lol), but I think a bit narrower should work, too. (Okay, I just looked up my glasses online and apparently I'm doing my measurements wrong, because online it says they are 131mm wide , which is great. those are the ones I have right now )

Thank you for those tipps. I'm going to try to do that.

And yes you are right in thinking I didn't tell anyone (If anyone found out I'd feel very silly :D) . I live alone right now, so that shouldn't be a problem and thank's for that excuse. I feel like that's another good reason to order more than one pair, because I'll be able to switch them every now and then and I can tell people I'm trying to find out which pair I like best.

Soundmanpt 18 Mar 2017, 12:57


I don't know if this will help you or not but there are 26 millimeters to an inch so the difference between 125mm and 130mmwould be less than 1/4" So you know how your glasses feel on you and how they look. Do they seem to be a perfect fit or do you think they could be a tiny bit more narrow? For what it's worth I have a sample case with over 75 pairs of women's glasses in it that I use for my non profit vision group I work with. Nearly all of them are between 130mm and 132mm. And I also use them for other young ladies and in every case my samples fit them perfectly. For that reason I think the ones you have shown me so far will fit you very nicely. I only suggested that other site to help you pass the time while you're waiting for the money so you can order your glasses. Good to see that you will be able to place your order next week. Please post which ones you order when you place your order. Of course you do know that when your new glasses arrive the first thing you want to do is take off your current glasses and put them in a glass case and then bury them in the bottom of a drawer and forget that you won them and start wearing your new glasses right away. Now that first day it's okay to be doing a lot of comparing your vision with and without your new glasses. But have your glasses at your bedside so as soon as you wake up the next morning you can slip your glasses on and try not to take them the whole day. If you need to clean them try not to focus on anything but rather look down while you're cleaning them. Would I be correct in thinking that you have told no one what you're planning on doing? Not a bf or best friend? If anyone asks you about your glasses since you only recently got your current glasses just tell the that you found a place on line that sells glasses really cheap and you just had to order a pair or two. Not even a lie.

oopsI 18 Mar 2017, 11:36

Awe, this post was so nice, Soundmanpt :) Thank you a lot for all the support with this. I do like my face a lot more with glasses on. Do you know how much of a difference 5mm in width of the frame will make, as the glasses I usually wear are about 135mm wide.

And thank's a lot for that other website. I'll stick to Zenni's right now because of the shipping costs and I found so many pairs I want already I'd rather not find any more awesome pairs. Once I get to a prescription I'll definitely keep for a while I'll check out more places to find maybe a few frames I like a lot.

I'll probably be able to order next week and keep you updated. Now all I have to do is choose the frames to order.

Soundmanpt 18 Mar 2017, 11:11


I kind of figured that you needed to wait to order your glasses until you had some money coming your way in April. Well the good news is that April isn't that far away anymore. So that just allows you even more time to check out other glasses that Zenni has, Oh and by the way if you run out of glasses on their site "eyebuydirect,com" is also a good source for ordering glasses. The only thing different is that i think they charge a separate charge for shipping per pair. So if you were to order 2 pairs you pay 2 shipping fees. At least I think that is true but you might want to check since you seem to enjoy "glasses shopping". Otherwise their glasses prices are about the same as Zenni. One of the things I liked about you right from you're first post was that you already had a nice very realistic goal of -2.00 as the prescription you want to end up at. Nothing extreme just a nice simple nearsighted (shortsighted) prescription for glasses. So yes that might seem like you're particular, but you're girl so that gives you the right to be particular doesn't it? lol I really think that you're going to get to your goal for several reasons. For one you seem to be very determined to do this and like I said you're not at all shooting for the moon by being happy if you can get to -2.00. Also unlike some that are starting off with completely perfect eyesight your eyesight isn't bad but it isn't perfect either so it's enough that you're now wearing glasses if not full time at least quite often now. Enough that your eyes are as you say "really uncomfortable trying to see without your glasses". You're right by the way that wavy effect you see without your glasses is caused by your astigmatisms. Also by first trying your mum's +1.50 glasses and now trying those +3.00 glasses you have a pretty good idea of what you can expect to see without glasses once your eyes have been changed. So your nit going into this "blindly" (nice pun right?) but with some knowledge of what to expect. And lastly since oyu have been wearing glasses you clearly must like how you look wearing glasses or you wouldn't be interested in making your eyesight bad enough that you will really need your glasses to see clearly. So I honestly think you will succeed. So for now you just have to wait about 2 weeks until you can order your glasses and then wait another 2 weeks for your glasses to arrive.

oopsI 18 Mar 2017, 06:06

Hey :)

I haven't left my glasses at home for the past 6 months or something. I find it really uncomfortable to see without them, because everything looks wavy. (I guess that's because I'm used to the correction of the astigmatism). I got my prescription changed about a months ago, but people are used to having me wear glasses all the time for around a year.

Today I've tried +3 glasses and that is about the maximum blur I'd like to go for (so about a prescription of -3.25 cyl. -0.5) and I'm not expecting to be able to get any higher than that anyway, at least not in axial myopia.

Antonio 17 Mar 2017, 20:51

Hi OopsI

How long do you have your first "car" glasses now?

So all people around you are already used to see you in glasses?

Best regards. Antonio

antonio 17 Mar 2017, 20:40

Hi OopsI,

i need to wear -6.5 myself in order to see.

I like women in glasses generally, also if they wear only -1 or -2 like you

Wearing stronger ones is not so cool sometimes, because you get pretty dependant on them to see and you can't simply take them off anywhere if it's raining or you do some sports and you can't let them stay at home any more

Best regards, antonio

oopsI 17 Mar 2017, 17:08

Next month I'll have some extra money, so I'll be able to pay for those glasses easily, so I'll just get the extra pair :D

I do love the way minus glasses look especially at a prescription from about -2.50 to -6.00. I'm very particular, lol.

Yeah, I was thinking 1.5 for the first two pairs and then go higher in the index, good thing to hear you agree. I would obviously not mind to get a little higher of a prescription than -2, but I don't expect it to work that easily, so -2 is my goal for now. And yes, I'm aware I'll have to get to about -4 for that. I hope this will work, I'm getting rather excited here.

Soundmanpt 17 Mar 2017, 15:48


It's very easy to tell that your desire to wear myopic glasses wasn't something you just woke up thinking about last week. You have clearly done some research before you spoke up in this thread. Needless to say you much prefer the way myopic glasses look compared to plus glasses. I totally understand needing to wait until you can get the necessary money to order glasses with. Most college kids don't have much extra money laying around. It is up to you if you want to go ahead and order a pair of -2.00 at the same time. In fact since you want to do that then as soon as they arrive go ahead and give the -2.00 glasses a try as being your stage one glasses. I am pretty sure that you will quickly find that they will be very uncomfortable to wear full time within a very short time. But then you know because if for some reason your able to wear them right away then you might want to send back the -1.00 glasses if they aren't needed. Zenni will do a half refund if you return them within a few days. Now if they are only a cheap pair it might not be worth sending them back because the return shipping could be more than you would get back. But I really think you will quickly find out that your eyes will be much more tolerant to your -1.00 glasses as your starter pair. As for as which lens option to get for your glasses you probably don't want to use the 1.57 lenses at all. Your lenses are going to be rather thin even with the 1.50 option with a -1.00 prescription. And I would stay with that for -2.00 as well because what you don't want to do is go with thinner lenses for the weaker glasses and then switch to the thicker lenses for the stronger glasses down the road because that could be noticeable enough to be questioned. Once you get to -3.00 or more you will see some cut-in. Now remember in order for you get an actual prescription of around -2.00 you will need to be able to wear -4.00 glasses. Your eyes will only change to about half of whatever prescription your wearing.

antonio 17 Mar 2017, 15:21

Hi OppssII

normally it´s really not necessary to go for an higher index at just only -2.

But if you really want to make them look only like -1,5 or -1,25 or so an index of 1,57 might help

in general at index 1,5 every diopter more make glasses about 1 mm thicker, at index 1,5 maybe even a bit more.

concerning shoes, I guess people will look more often to your face than to your shoes ? :-)

best regards, antonio :-)

oopsI 17 Mar 2017, 14:11

Also one question, do you think it makes sense to go for the 1.57 lenses instead of the 1.5 for the stronger pairs?Will the change in prescription be less noticeable? I don't want people to notice what I'm doing and don't mind the glasses looking less strong for now (I do want to maybe have a little cut in at the end, but that can wait)

oopsI 17 Mar 2017, 13:03

I did give it quite a bit of though. Thinking back, I have always liked people with minus glasses even (guys in minus glasses were always preferred :D) I think this is the right thing to do. I'll be ordering in two weeks, once I et money. I really want to order a stronger pair, too, so I'll probably order a minus two one without any additions for 6,95, too.

Soundmanpt 17 Mar 2017, 09:59


You didn't really say how much you wear your current glasses, but I assume that you don't wear them full time but only when you feel you need them. But even wearing them part time i'm sure that you would quickly notice the difference of not having that coating on your glasses. And since you will be wearing your glasses constantly when you get them I have a feeling that by not having that coating would soon become annoying to you. Zenni actually offers 3 different versions of AR coating but I always order the $5.00 version and they work just fine. Having the AR coating will make wearing your glasses more comfortable to wear full time and that is important. I'm sure that you're having a lot of fun glasses shopping in the Zenni site. It's amazing just how many pairs of glasses they offer. I tell people all the time that without a doubt they offer more glasses than any optical store has on display. I noticed when you showed me some of the first glasses you were planning to order that you apparently already figured out what size glasses fits you best. They were all around 130mm "overall width" so did you measure your own glasses across the front and used that as a guide? That is the right way to do it so you know that they should be a a really good fit when you get them. You clearly have given a lot of thought about wearing glasses as you even said for quite a few years already. And you didn't just want to wear glasses but you wanted your eyes to be myopic. So even with needing plus glasses when you were 13 you never bothered wearing them because that wasn't what you wanted your eyes to be. So i'm sure you were thrilled when you found this site and found out that you might be able to make your wish come true. You even have a desired prescription in mind that you want your eyes to be when you go for your next eye exam. Nothing very strong but enough that you will have a good reason for wearing your glasses all the time. You just want glasses to be a part of your day to day look. So without a doubt getting some fun glasses to wear should be included. You're correct that many women do in fact collect lots of pairs of shoes, so nothing wrong with wanting to collect many pairs of glasses. If you think about it i'm sure more people will notice your glasses than your shoes. When are you planning on placing your order for glasses? I know you said once that you would be ordering in April but I think that was when you were planning on ordering several pairs instead of just one.

oopsI 16 Mar 2017, 16:28

I do have AR coating on my glasses, yes. I think I'm going to get it, it would be stupid to safe money on that and then not wear those glasses.

I actually also found a ten dollar pair I really like. The colours are a little bold, though. Not an everyday thing, I suppose, I might be getting them just for fun, though.

I forgot how much I love to shop for glasses and now that I can actually afford more than one pair I want to buy them all :D Other girls buy shoes, I buy glasses.

Soundmanpt 16 Mar 2017, 16:17


Of course I mean when you take off your glasses not while wearing them.

Soundmanpt 16 Mar 2017, 16:16


The AR coating is really up to you. You don't seem to do much driving and even if you not having that coating would only be somewhat annoying to you. Do you have AR coating on your current glasses? If you don't then i'm sure you wouldn't miss not having it, but if you do then you might notice it a good bit more. So now you have a pretty good idea what to expect as your eyesight starts to be changed. How you were seeing wearing only your mum's glasses is nearly exactly what you can expect to see by the end of each day when you take off your glasses for bed. The way you tested your eyes was the right way to test and not with your own glasses on under them. Now you should understand why I don't want you to start off with glasses too strong. By wearing her glasses you now know about how much wearing -1.00 glasses is going to change your eyesight. So now based on that think how much more fuzzy and blurry everything will be when you start wearing -2.00 glasses.

oopsI 16 Mar 2017, 15:47

It makes a lot of sense to do it that way. Shipping is around ten bucks, and I actually found a pair that looks very similar to the one I have right now and and they are a little cheaper (including shipping and anti reflective coating it's 30 bucks)

Do you think it makes sense to order them with anti reflective coating if I don't plan to drive in them? And -1.00 shouldn't be too strong, right?

As I was not wearing my glasses under my mum's reading was a little uncomfortable with them, because everything looked a little fuzzy. Distance was fine, obviously blurry at about 1.5 feet from my face, but comfortable and I could function very well, which is what I'm hoping for.

Soundmanpt 16 Mar 2017, 15:22


I'm glad that you agree with me and only plan on ordering just the one pair to start with. Zenni's glasses aren't that expensive but since you like ones that are slightly more than the really inexpensive ones I don't want you to buy glasses that might be too strong for your eyes. When you got your eyes examined when the optometrist was changing from one lens to another in front of your eyes you apparently was more comfortable seeing at 2015 than you were at 20/20. So right now your eyes are very slightly over corrected with your glasses on. By wearing your mum's +1.50 glasses that is very close to what your eyesight will be like once your eyes adjust to your -1.00 glasses and take them off. So how well were you able to read wearing her glasses? And how blurry was things at a distance with them on? Is that what you're hoping for as a nice start to inducing myopia?

oopsI 16 Mar 2017, 15:04

Hey antonio

No, actually only -0.25 and -0.5 cyl. Very minor, but my vision improves a lot when I wear them.

antonio 16 Mar 2017, 15:01

Hi Oopsi,

Oh you already wear them full time? Wow. How string are they ? Ah you said about -1 and -0.5 astig? i See. :-)

Besteht regards , antonio

oopsI 16 Mar 2017, 12:22

Yes, I need glasses for driving, that's the reason I got them at first. My apparent sensitivity to correction might be the reason why I'm a full time wearer at this kind of prescription aside from just liking to wear them in general.

antonio-o 16 Mar 2017, 11:48

Hi oopsi,

according to what you said, you already need "car glasses".

oopsI 16 Mar 2017, 09:25

Thank you, that makes sense. I guess I'll order only one pair, then. Once I've seen how well my eyes adapt I'll probably be able to order stage 2, 3 and possibly 4, right?

Over here you need 0.7 or a little better than 20/30 vision to drive in either eye. Without correction I have 0.4 (which would be something between 20/40 and 20/60 vision in my left and) in my left and 0.6 in my right eye, so yes, I guess I'm pretty sensitive to correction. With correction I have 20/15 vision.

Also I decided to test again how able I am in dealing with being short sighed by wearing my mum's reading glasses around the house for about 30 minutes and I really didn't mind much (they are +1.5D)

Soundmanpt 16 Mar 2017, 09:03


I'm not sure how long the shipping will take getting to Europe. I do know that a year or so ago someone I was in conversation with in England received her glasses within the normal 2 week time frame. She was also concerned about how long it might take to get her glasses. She also got her glasses from Zenni. The glasses are made in China then shipped to California here in the US and then mailed from their. Zenni actually makes your glasses within the first 24 hours after receiving your order. Getting two or even three pairs at once is really good because you would be saving the shipping charge and also you would already have the glasses in hand when your eyes are ready for the next stronger ones. But it is impossible to know how your eyes are going to react to over corrections. I'm afraid that you don't realize how much difference wearing -1.00 glasses will be to your eyes then your own -.25 glasses? And actually your -1.00 because of your -.50 astigmatism will be more like wearing -1.25 glasses. If you don't feel like the Lennon glasses won't suit you that well, then you should consider a different pair for your starter glasses and plan on wearing them full time. I think that trying to wear -2.00 glasses to start with is going to be much too strong for your eyes. Most people wearing -2.00 glasses need their glasses full time by that point and you would be going from hardly any prescription to that strong right away. You really need to get glasses that you're able to wear both for reading and studying as well as for seeing distances with. Not one weaker pair for reading and one stronger pair for distance. For example if you were in class and you were wearing -2.00 glasses you might be able to see the board in the distance with some effort, but then if you needed to take some notes your glasses would be too strong to see anything close very well. You don't want to be switching from one pair to the other like that. You need to make your second pair of glasses your stage 2 glasses. But until we see how well and fast your eyes adjust to the -1.00 glasses it is very difficult to suggest what prescription you should get. I don't expect it to take all that long for your eyes to adjust to the -1.00 glasses. But you or I won't know that until you start wearing them. If it only takes you a month or so for your eyes to feel completely comfortable wearing your glasses and you're able to see perfectly wearing them for both reading as well as distance then then you should be able to order your stage 2 glasses but even then I think -1.75 might be a better option. Going to -2.00 would be a really big jump. If it takes much longer for your eyes to adjust to your -1.00 glasses then the stage 2 glasses should only be -1.50. Actually I think that your eyes maybe somewhat sensitive to correction. I am not sure but I think Europe is the same about driving as it is here in the US. If you're unable to see the 20/40 you are required to wear glasses when driving. You said that you got you're most recent glasses when you failed the driver's test. So unless they require you to have completely perfect eyesight I don't how you failed the vision test. Without your glasses you should be able to see all of the 20/30 line and some of the 20/25 line. As your eyes adjust to the -1.00 glasses you will find it difficult to see the 20/50 or 20/60 line without your glasses. If you're interested there are couple of simulator sites that you can go to and by putting in the full prescription of the glasses you plan on wearing for stage 1 you will get an idea what your eyesight will be like. Let me know if you want be to post them for you.

Cactus Jack 16 Mar 2017, 07:23

That Guy,

When you get to the point where you put on your glasses first thing in the morning, wear them all day, and read comfortably for long periods with them, it is time to step up tp the -2.00 g;asses. -1.00 is typically easy to get used to. The key is the reading.


That Guy 16 Mar 2017, 02:54

Hey so I got some -1 glasses. gow will I know when Ive ajusted to them? everything seems to be pritty normal. Thanks.

oopsI 15 Mar 2017, 13:20

Oh, okay, perfect. I'd like to order at least two pairs at once, shipping to Europe doesn't seem to be terribly expensive, but it takes a few weeks from what I've gathered and I don't think I'd wear the Lennon glasses full time as I feel like they might not suit me at all, so I'd be more of an at home/costume thing.

Do you think I could handle -2.00 for most of the day? If so I'd probably just order -1.00 in the Lennon glasses to wear at home and another pair with a stronger prescription to wear throughout the day. If I'm able to handle them well I could wear them at home, too.

Also would you advise me to order a third pair, too?

Soundmanpt 15 Mar 2017, 12:34


I may have confused you as well. What I thought you meant was that you were planning on only wearing your actual prescription for reading. But if you're planning on using the SPH -1.00 Cyl -.50 for reading that should be perfect. But I think you're fine with just using those same glasses as your full time glasses for everything. Honestly I really don't think it will take 2 or 3 months for your eyes to be completely adjusted to your glasses. For that reason you might be better off going with the much cheaper Lennon glasses in case your eyes are ready to go stronger much quicker. There is no way to say how long before you will be ready for stage 2. Depending on how fast your eyes adjust to your first glasses will also give you, and me, a better idea of how strong to go with your second pair of glasses. If your eyes adjust really fast that means that your eyes are more willing accept a stronger prescription for your second pair. if it takes longer then we need to not be very aggressive. Going a stage at a time is fine since you like thew idea of ordering different glasses for each step anyway.

oopsI 15 Mar 2017, 11:20

Thank's a lot for your advise. I didn't notice the red templates, thank's for mentioning them.

I think I misunderstood what you said, then. I'm absolutely planning on wearing too strong glasses all the time, though. From what I've read in the thread, though I thought I might be able to start with a -1.00 for reading and I could wear stronger ones for lectures, etc. ... because I'm not accommodating as much, but I guess I've misunderstood that.

Do you think I could start with sph-1.00 cyl-0.50 for both eyes? I'd probably go for #4420725 there.

I'm guessing I'm not going to wear that prescription for more than two to three months or so and the ones in the next stage for a longer time? If so I might order #2015215 (light brow/red. Also thank you for the warning, but from the shape they look exactly like the ones I already have) and the Lennon ones for that stage

Do you think I could go sph -2.00 cyl -0.50 for that stage?

For the third prescription I'm thinking sph -3.00 cyl -0.50? I'm contemplating these: as well. I'll have to think a little bit, but as I have to wait for April before I order anything anyways I do have that time.

Do you think those prescriptions could work or are they too high? I could go -0.25 lower in sphere for all of them?

I really appreciate the help!

Soundmanpt 15 Mar 2017, 10:24


That's really great that they were nice enough to provided you with everything you need in order to your glasses including your PD. They clearly are a place you should recommend to others. If people around you are used to seeing you wearing different glasses now then it would be fine to order different glasses to induce with. As for the glasses you have picked out I actually like all of them. You're young and being in college i really think the first ones that are only $9.95 would without a any doubt be a fun pair to wear and should be very comfortable as well. Since you always wanted glasses in the John Lennon style anyway they should be a a for sure buy. Then the next glasses #4420725 are really nice as well and again very much in style I think the tortoiseshell color would be a good look. No I don't see any red in them at all. The next glasses you have under consideration #2015215 look nice but be careful about where the bridge of the glasses is located. That could mean that when you have your glasses up in place on your nose that the top of the frame could be blocking out your eyebrows. You normally want the top of your frame just slightly below your eyebrows. Also did you notice that they have red temples? Would you be okay with the front being light brown with red temples? Lastly #207412 is another nice looking frame and I assume you would be getting the grey color? I like that the frame is made with very flexible plastic. That's nice if you watch much TV and now that you will be wearing glasses to watch TV if you happen to fall asleep with them on they are less likely to get broken. They also look like they would be very comfortable to wear. Have you decided on what prescriptions you plan on ordering yet? What were you meaning about "less strong ones for reading and studying" If you're serious about inducing myopia whatever prescription you decide to wear to get started is what you need to be wearing all the time. Actually the more close work you do such as reading and studying wearing -1.00 glasses the better it is with inducing myopia. Your eyes should be able to tolerate -1.00 for reading okay. That was why I said you shouldn't try going too strong with your first glasses. Now that you have your full prescription in hand be sure to include your CYL and axis when you place your order for glasses. So over all I really liked the glasses you have picked out. Now you have to pick which ones to order. But like you say for $10.00 I think one is a for sure pick.

oopsI 15 Mar 2017, 04:12

It worked. The young lady whom had already done the text on me was very nice and understanding, when I explained that I really just wanted a cheap pair for driving and gave me everything I need, including PD, etc. ...

Now I'm wondering, you say I should order similar frames, but if I'm going to wear them full time I want some that look nice, so do you think I can choose a cheap frame (and no anti reflective coating) for the less strong ones which I'm going to study with and for the -1.25/-2.25 ones go with a more expensive frame? Also do you think I could choose two different frames for those? I switch between pairs of glasses anyway. And is there any sort of frame I should NOT go for? I was thinking to go for those: (I always wanted John Lennon/Harry Potter style glasses, not to wear full time, but for ten bucks and for reading I wouldn't say no) (they appear to look similar to those I have now, I have colour vision problems, do those look red at all?) (I always wanted light brown glasses) (I was also considering these)

oopsI 14 Mar 2017, 17:38

*failed the vision test, not felt

oopsI 14 Mar 2017, 17:26

I'll see. I'm just going to be open and tell them I don't have any money to get a good pair right now if I'm just going to leave them in my car anyways. For 35$ I could get a new pair at the cheapest place near me, but if they want a few dollars I'm just going to pay them, that's fair, I think. I mean they did the work, so I should pay them.

And yes, I know I'm barely myopic, I'm just happy it's moving in the right direction anyway, because that gives me hope that I might be able to achieve axial myopia.

For the driving part, I don't really drive, but I mainly got a new pair of glasses, because I felt the vision test to get my license. I drive a few days a year and I'm going to make sure that I see properly when I do drive during this experiment.

Thank you for the advise .


Soundmanpt 14 Mar 2017, 13:39


I always worry that I might be confusing someone even though I try to keep it simple. So i'm glad to see that you weren't confused at all with my answer. You did very good with remembering what you did. The fact that you have bought several pairs of glasses from where you got your eye exam may be a help to you but at the same time i'm sure they don't want you to lose you as a customer either.It's possible that they may want to sell you the price of an eye exam in order to give it to you. I know that a place near me that operates the same way as where you went will sell the prescription for $35.00. That is possibly what they may offer you as well.It helped that your prescription is the same for both eyes except for the axis which is very normal. I don't need to tell you that you're barely myopic at -.25, but it is better than nothing at all. So i'm sure that you're going to notice a nice difference when you get your -1.00 glasses, but you will like how sharp and clear everything will be. Now you mentioned that you drive a car so make sure that your eyes are seeing good with your glasses on before driving with them. You want your depth perception to be good driving wearing them. This shouldn't be a problem for sure after maybe the first day of wearing them. Your eyes should adjust to them rather quickly. Even the first night when you take your glasses off at the end of the day things will be much more blurry that they are now when you take your glasses off. But the blur will only last a few minutes before your eyes return to normal. Each day that blur should remain a little longer when you take off your glasses.

oopsI 14 Mar 2017, 12:52

Thank's a lot, you didn't confuse me at all.

I will go back and ask, I've bought glasses from them twice and got my lenses changed there, too, so I hope they will allow me to get the full prescription (yes it is the same in both eyes, just different axis for the two lenses. They wrote it down on a piece of paper and I looked at it to check what changed, sadly I don't I only remember one of the axis' and I don't know which eye that was for).

I guess the reading glass thing is just an excuse to allow myself to actually make my eyes worse on purpose :D

If you think going -1.00 more for both eyes right away I'll believe you. I'll let you know how it goes and I'm happy for any sort of advise I can get.

Soundmanpt 14 Mar 2017, 12:28


You should at the very least push back any need for reading glasses somewhat i would think. So that's a problem with going to a place that says the eye exam is free. They can refuse to provide you with a copy of your full prescription. I'm surprised that they even gave you that much of your prescription. By the way all you said your eyes were SPH -.25 and CYL -.50 is that the same for both eyes or did they only tell you what one eye was? You do have several options. I would at least go back to where you got your eyes examined at and ask for a full copy of your prescription. The worst that can happen is that they will refuse to give it to you. Then check to see what the very cheapest glasses would cost you without any extras and of course don't even consider it unless they will then give you a copy of your full prescription. The other option you have is to say "no thank you" to them and walk away. Then go on-line and pick out the glasses you want to be wearing. Personally I think Zenni is the best place to get your glasses from. ( Now let me explain something to you about eyesight that might help in your case. If you were going in for contact lenses most doctors would suggest dropping the CYL completely and simply adding an extra -.25 to the SPH. So if you were wanting contacts the doctor would write you a prescription of -.50 for contacts and no CYL. Now the doctor would also tell you that doing this isn't qute as good as it would be with the CYL included but because contacts for astigmatisms is nearly 3 time more expensive than regular myopic lenses the difference is so little that going with just the SPH only is the better option.So were already taling about adding extra SPH anyway so you can work on inducing myopia. So since you can buy glasses for as low as $6.95 from Zenni in whatever prescription you decide. They have several hundred to choose from for under $13.00. This would be a much better option than buying glasses that you have no real intention of wearing just so you can get your full prescription. Now let's talk about what prescription to order as your first pair to get started with. I'm sure you want tot be aggressive but if you start off too strong it could make wearing your glasses more difficult for you. I your eyes would be okay wearing -1.25 glasses for distance, but because you're in college and need to be doing a good deal of close work such as reading that might be too much for your eyes to handle. And remember that it is critical that you keep your glasses on constantly. So why not go with a nice simple -1.00 for both eyes as you're first glasses and leave off the CYL. Doing this I suggest that you just order the one pair only at first. But as soon as you find that your eyes are adjusting to them without any problem then you should go ahead and order a second and third pair using the same frame if possible. The 2nd pair should be -1.75 and the 3rd -2.50. Now I know that you said you are only wanting your eyes to get to around -2.00. but you're eyes aren't going to change to the prescription of the glasses your wearing. So to get to a real -2.00 prescription you may need to go as high as -4.00 glasses because your eyes will only change to about half of what the glasses your wearing are. I hope I didn't confuse you too much. .

oopsI 14 Mar 2017, 11:18

Thank you :)

I don't expect that a need for reading glasses when presbyopia sets in will completely perish, but most moderately myopic people can at least read a little easier, right?

Right now my problem is I don't know the axis, so I'd have to go back and admit I want to order online, I guess.

Where I live we don't usually pay for the exam at the optometrist's, as long as we are there to have glasses fitted. I guess I'll tell them I want a cheep pair I can leave in my car.

I mean -0.5 D in ten months isn't too bad I guess, I'm hoping I can keep this up for a few more years.

Also I've read a lot of the tips. My comfortable reading distance can be as low as 10 centimeters, do you think I can start with -1.25 right away?

Soundmanpt 14 Mar 2017, 10:40


Well it at least seems as though your eyes are heading in the right direction. From when you were 13 anyway. College with all that is required of the eyes seems to have an effect on so many. Being 20 you are nearing the age where it could be start to be more difficult to induce myopia. I honestly don't recall ever seeing anyone saying that they had any regrets about inducing myopia. But being myopic may slow down the need for reading glasses but I can't say that it will assure that you won't still need reading help later in life.I suggest that that you go back in this thread and read the advice already provided to others about what you need to do. In short you need to order glasses stronger than you were recently prescribed. Cactus Jack and myself both recommend that when you order glasses it is best to order the same frame but with 3 different prescriptions. That way as you switch for a weaker one to a stronger one no one will notice. In your case I think you should order glasses with -.75 -1.25 and -2.00 lenses and only change the SPH include your CYL and axis as it is in your prescription. When your glasses arrive wear start off by wearing the -.75 glasses from the time you open your eyes each day until you close your eyes that night for bed. Once you're eyes have become completely comfortable wearing those glasses without any problem then switch to the -1.25 glasses and again wear them until everything is sharp and clear and you're completely comfortable wearing them before going to the -2.00 glasses. The most important thing isn't as much about the strength of the glasses but that you wear them every minute of everyday.

oopsI 14 Mar 2017, 09:10

Hey :)

First off I'll explain my situation a little. I'm 20 and I wanted to be myopic for quite a few years. I was prescribed +1 diopter when I was 13 but never really wore these glasses. I didn't really do anything to become myopic, no knowing that that was possible.

After taking a vision test to get my drivers license about two years ago I got myself a pair of glasses, I really started wearing them 11 months ago (both eyes sph: +0.25 cyl: -0.25) because it really helped with headaches and I like the pair I bought. A month ago I went back to my optometrist to have my eyes checked (I didn't study for the exam and it was a few hours after I got up). Now my prescription's sph: -0.25 cyl: -0.5. (Maybe because i started med school last summer and I'm barely outside anymore)

Now do you think I could get true axial myopia up to maybe -2D?

Also I was wondering if there has ever been someone on here that regrets inducing myopia? The thing is I find the idea of not needing reading glasses when I'm older really exciting and I feel like it'd be worth it for me.

Thank you for your help!

P.S. I apologize for any language mistakes in advance, English isn't my first language.

Hello,We discussed my vision and you helped me understand a lot of things,i just took an eye exam and my eyes are really fine she said,The eye doctor,She exactly : said you are little myopic and all humans are myopic but very little you can't even notice it,She said don't stay long hours in front of a computer and look at distant object each 20 minutes in front close objects,Also she tested it with a computer,I was disappointed, and i am in a place that i can't get eyeglasses in stores without an eye test paper, That means i must order it online, which prescription should i start with ? I told you before that i can see fine and clear with my sister's glasses which is -0.75 , -0.50 , should i start with -2.00 I want to be myopic before next December, will make it in time ? also i see with the -0.75 , -0.50 better than without glasses btw.

Soundmanpt 10 Mar 2017, 16:07

Kostas T

Your honesty is appreciated. But you have to understand that there are 3 major factors to induce myopia. The first one is age, your not even 15 yet so that takes care of number one. As you may know once you're past 18 it gets harder to induce myopia. Number 2 is wearing either glasses or contacts completely full time. That means you must wear correction every minute you're eyes are open from morning until you go to bed that same night. I'm sure you feel like you're wearing your glasses long enough each day by having them on for 9 hours, but giving your eyes a 2 hour break defeats everything you have been doing. Number three is wearing stronger glasses than you need and slowly increasing the power of the glasses as your eyes adjust to each prescription. You seem only to want to create a need for glasses that you consider to be a decent prescription but not overly strong. So if you're intention is to end up needing -2.00 glasses you will probably have to wear -4.00 glasses. You're eyes will only be changed by approximately half the value of the glasses you're wearing. No surprise that people think you're more attractive wearing glasses. For many young ladies glasses often times will enhance your looks. This is why glasses have become so popular even as a fashion accessory for so many young ladies. Do you live in a place where you can get glasses without having an actual written doctor's prescription? Don't change the lenses in your glasses until you're eyes are completely comfortable wearing the glasses you now have.

Your response was full and descriptive.! I have been wearing glasses since elementary school. I had +1,75 hyperopia. The last two years its swapped completely to what already know. I get really good comments on my glasses some people believe that I am more beautiful with them on! Hahha okey I wear them from 8 till I return back home. There is a break for about 2 hours and then again the go on. I wear them for more than 9 hours per day. Anyways I ve noticed that my left eye, which has the -1 on is seeing kinda better than the right with the -0,75. Im looking forward to changing both of the lenses to -1,50 but I am not sure if the right will go on well. I believe it will.!I bought my glasses from a nearby optician shop the frame was free I just I had to pay for the lenses that's all. Again now am gonna pay the lenses.

So you already have glasses with O.D.-.75 / O.S. -1.00 lenses. That's a perfect prescription to start your eyes wearing. But I get the idea that you aren't wearing your glasses full time? Wearing your glasses part time won't help you with inducing myopia. If you're really serious about wanting to make your eyes more myopic you need to start wearing your glasses from the time you open your eyes in the morning until you close that night for bed. Wearing your glasses for 8 hours but then taking them off for 6 hours isn't going to do anything to your true eyesight. You want your eyes constantly seeing only with prescription lenses in front of them. When you say that outside in the sunshine at times things in the distance is slightly blurry with your glasses on it's possibly because you left off your astigmatism. Even though you only have a small amount of astigmatism it's still enough to cause things at a distance to be fuzzy or slightly out of focus to you. Not a big deal though. When you're tired so are your eyes of course and remember wearing your glasses all day your forcing your eyes to focus constantly and for a few seconds your eyes might loose focus. I think mostly what you're experiencing is your eyes still adjusting to the prescription of your glasses. And the more you wear them faster your eyes are going to fully adjust to them. What your wanting is for your glasses to become so comfortable that you hardly notice that your wearing them and for your eyesight to be be perfect with them and blurry when you take them off.

Just curious where did you get your glasses from? I assume that you have been wearing your glasses to school? Have you gotten some nice comments on your wearing glasses now?

Samsamsam 09 Mar 2017, 07:50

@ Kostas T

If I were you, at 14 yo, I would buy -3 or -4 contact lenses (with good oxygene transparency) and wear them constantly. After 3-4 months switch to -5 (if no problems), then -1 more and after 1 or 2 years degree of myopia will probably be at desired level.

Kostas T 09 Mar 2017, 06:21

I had tried some -1 contacts and i didnt like them at all. I wont take any else. anyways my current glasses are od -0,75 and os -1. Rarely especially outside in the sunlight i see kinda the backroung is 'burnt'. i believe this is a 'consequece' of concave lenses.. when im tired and i wear the glasses the whole day long, for some secs the vision gets blurred and i see better without them.. That must be about the cilliary muscles and accommondation . i dont bother. i dont want high prescriptions some people put contacts and high lenses with the opposite power. its called goc? i dont know. So, you believe its gonna be better if the power of the lenses is equal? If i go to -1,5 on both, the difference for the right eye (previously -0,75) its gonna be kinda tough.. tell me

Soundmanpt 08 Mar 2017, 10:05

Kostas T

Okay I think the confusion is because what you said you were prescribed. So let's leave off the astigmatisms for both eyes. meaning you were prescribed for your left eye O.S. -.25 and for your right eye O.D. -.50. But then you said that you ordered your contacts as left eye O.S. -1.00 and your right eye O.D. as -.75 So that would mean that you were over correcting your left by -.75 and your right eye by -.25. But I think what you meant to say was that you were increasing both eyes by -.50 so you're really wearing a -.75 contact in your left eye and a -1.00 contact in your right eye. Since this apparently is the first time that your wearing corrective lenses you were right in not trying to be too aggressive. You did get glasses in your actual full prescription I see and then you ordered your contacts in the stronger prescriptions. I'm sure your eyes notice the difference between wearing your glasses and wearing your contacts. Are your eyes adjusting to seeing with your contacts pretty well now? I'm not really surprised that you were able to see rather well wearing your cousin's glasses. You have clearly done your homework about vision because you're right that being as young as you are your eyes should be able to wear glasses much stronger than you need very easily. You seem to have been experimenting by trying on other people's glasses. But one thing you do have wrong is thinking that contacts are cheaper than glasses. I'm not sure where you got your contacts from or what you paid for them but you can order glasses on line from for as cheap as $6.95 and even have a decent selection to choose from but for under $13.00 there are several hundred to choose from. You can even add on an optional AR coating (anti-reflective) which is nice to have on your lenses for $5.00 more. The shipping is only $5.00 and you get your glasses in the mail in less than 2 weeks. When you do start ordering glasses you should include your astigmatism as well. You only have a slight astigmatism in each eye but surprisingly having included will sharpen your eyesight enough to make a difference. You said that you prefer to wear glasses which I assume is the main reason you're wanting to induce myopia is so you can wear glasses with a decent prescription. Do you have a goal in mind that you want to be wearing for glasses which will make you happy? As for my opinion I think that wearing -1.00 / -.75 for your first prescription is a good starting point for you. You're getting your eyes used to seeing with a prescription. I'm sure that things are noticeably more blurry now at the end of the day when you take off your contacts than they were before you started wearing contacts. But for now while you're sleeping your natural eyesight returns and the blur is gone when you wake up. That is normal but the more you wear your contacts the longer the blur will remain. Once your eyes are seeing everything perfectly wearing your lenses that is when you need to be placing your order either for contacts or glasses. And as for your next contacts if that is what you decide to continue wearing I would only order -1.50 lenses for both eyes. You probably should try and bring your better eye up to the same prescription as your weaker eye. Also that way you can order less contacts as well. If you decide to get glasses then you should include your astigmatisms as well so both eyes would be -1.50 -.25 with the 2 different axis's. Do you have any other questions?

Ladies wearing high plus glasses i find beautiful, sexy and very loyal as friends and in relationships I once dated a lady with plus 11 glasses she was so beautiful and loyal. Sadly I move away and we lost touch. I would always date a lady with high magnification glasses because of there wonderful personal attributes. Have fun ladies take good care martin,xx

Kostas T 08 Mar 2017, 07:22

i've tried a contact lenses pair and i thought it will be cheaper for me to but montlhy disposable contacts. I prefer glasses though...! iam 14,5 years old and i believe iam from the lucky ones who can accommondate in any prescription!hahha my cousin has -4 and i could handle it pretty well! anyways, i took these -1 and -0,75 because i thought i should equally raise up the sphere. so an -0,5 was added in both of them resulting of the known prescription. that was the reason why i didnt take the -1ones... Whats your opinion on that? What should it be the next sphere?

Soundmanpt 07 Mar 2017, 17:15

Kostas T

I assume that you recently had your eye's examined and the result of your eye exam indicates that you only have a very slight need for glasses if at all. You said that you understand what the numbers of your prescription mean so I won't bother going over that. But I do have several questions for you if you don't mind. First of all what is your age? That is a critical part if you intend on inducing myopia. Also since your SPH is -.25 in your left eye and -.50 in your right eye why did you order lenses of -1.00 for your left eye and only -.75 for your right eye? You actually should have simply ordered the same -1.00 for both eyes. Even better if you were ordering contacts and not glasses since you could get by with only one box for both eyes. If you're getting contacts I agree you don't need the astigmatism correction enough you make much of a difference to your vision. Is there a reason you're planning on wearing contacts instead of glasses?

Kostas T 07 Mar 2017, 12:33

Kostas T 07 Mar 2017, 12:25

Part 2

After one month i bought the frame with that lenses i was not that convinced with myopia vision quality so i ordered my optician some OS -1 and OD -0,75 lenses. I thought i ought not to use any cylindrical correction as its not recommended. Although, i didnt like the cylinder that i had on my prescription.

I've been wearing that specs for about 2 months. I would like to induce my myopia

Kostas T 07 Mar 2017, 12:24

Part 1

Hi guys

I was prescribed the following OS -0,25 -0,25X70 OD -0,5 -0,25X50.

I now exactly what these numbers mean. I've read many articles and information about optics and ophthalmology (mostly from Tim Root I look forward to becoming an ophthalmologist specified in paediatrics. Currently, i am running a project with some presentations to my class about refractive errors with an on-stand experiment taking place!

That Guy,

I like working with young people who want to learn and are willing to work. I have done a lot of industrial teaching. In the industrial world, the students are adults, at least in spirit, and WANT to be there and WANT to learn. It is a joyful occasion for both the students and me when I see the "light come on" as UNDERSTANDING dawns. By the way, I don't encourage "rote" learning. With rote learning, you typically wind up knowing how to solve one or two typical problems, but if you have understanding, you can analyze and solve almost any problem that comes along.

I would like to encourage you to learn as much as you can about how vision works and the math and physics of what we are doing. Here is a link to a paper entitled "The Eye". You might find it interesting.

Please let me know what you think.


That Guy 02 Mar 2017, 10:29

Cactus Jack,

Oh and might I add coolest 79 year old ever, you can use a coputer and you seem to care about the impacts of missonformation. Most people I know your age think anyone younger then them is wrong by default.

That Guy 02 Mar 2017, 10:24

Cactus Jack,

My best subjects are chemistry, physics, informatics and english language which is basicly hyperanaylising sentances and geeking out with the teacher over dead poet socity. ya know the kind of stuff someone with myopia envy would do :p

Cactus Jack 02 Mar 2017, 10:15

That Guy,

Frequently, but I only get involved in technical discussions and pretty much stick to those. I have done a lot of industrial teaching and my answers tend to be a bit long because I want t foster UNDERSTANDING, rather than just parroted responses.

I am semi-retired, but stay pretty busy. I am 79. I am NOT an Eye Care Professional (ECP), my background is Electronics and Computers. I learned about vision and optics because of unsatisfactory answers I was getting from ECPs. I took Physics in high school and university, but most of what I have learned about vision and optics is thru self study and research.

May I ask your interests and subjects you like best in school?

BTW, it is 11:15 AM, Thursday, in Houston


That Guy 02 Mar 2017, 09:54

Cactus Jack,

Thanks for your help, Ill start with -1.0

are you on here often? Just you are very helpfull and think it would be good to be able to ask you more questions along the way.

Cactus Jack 02 Mar 2017, 09:49

That Guy,

Don't start with -2.50, it would be too much do deal with initially. You need to strengthen your Ciliary Muscles. You do that by starting with a Sphere correction of -1.00 in both eyes. When you get comfortable with those for all your activities including reading with them, increase to -2.00. It may take a month to be able to go from -1.00 to -2.00. You might consider order both at the same time with the same frame. Later, you might want to try some -3.00s. When you get pretty used to the -1.00 glasses and are thinking of transitioning to the -2.00s you might want to consider an eye exam to get a better measure of your progress. We need to talk about that before you do it.

In some ways, it is like going to the gym. You don't start muscle training with a heavy weight, it is better to start with a light weight an do many repetitions.

Your Ciliary Muscles are the strongest muscles in your body for their very tiny size. The get a lot of exercise as you change focus. The first step in Inducing Myopia is to strengthen those muscles. Wearing progressively stronger glasses will do that.

I am guessing that it will take about 6 months of wearing progressively stronger glasses to yield significant results. It is possible that because of the myopia in your family, it may happen more quickly, but you need to get started as soon as possible. You are approaching the age where your genes will stop the development of any Axial Myopia. You can develop Pseudo Myopia until Presbyopia puts a stop to that, usually in your mid 30s to early 40s.


That Guy 02 Mar 2017, 09:09

Cactus Jack,

Melbourne would be my timezone. 3am right now :p.

I found an Australian based website to get glasses simply because the shipping is faster.

So -2.5 will (if it works) give me around what level sight?

also Im ready to wear them for a long time but could I get an estimate? Just based on your best quest as I rilse it will differ from person to person.

Will it be hard to function with these glasses? or at least hideable? what should I expect?

Cactus Jack 02 Mar 2017, 05:39

That Guy,

Not a problem, I was just looking to possible symptoms to report if you go for an eye exam to give you a better chance of getting a prescription for glasses. I am considering the possibility that your actual prescription may be so low that the examiner may not prescribe glasses.

We don't really care, but you may need a reason to justify wearing glasses to your parents. If you have a credit card and a mailing address you can order glasses online from Zenni Optical. You might check out their website.

They have single vision glasses for as low as US$6.95. The frame is the controlling factor until you get into very high prescriptions. Most of the frames are a bit higher than that, but they are there, just a little hard to find. If you decide to pursue this, you need to pick a frame that you like and be able to order several pairs of glasses using the same frame, but increasing Sphere prescriptions. Once people are used to seeing you wearing glasses, you can slowly increase the Sphere prescription IF you don't change the frame style and few people will even notice. The ONLY option you need is perhaps the low cost Anti-Relective coating (A/R). You only need the standard lens material with an Index of Refraction around 1.50. You don't need any of the high index lenses. Your lenses won't be very thick anyway.

May I ask where you live (city) in Australia? I live in Houston, Texas. Only asking to determine the time difference.


 02 Mar 2017, 00:32

Cactus Jack,

Sorry :p, I dont curently drive and honestly with public transport in the city I dont think ill really ever need to. That said I do plan on learning to drive to go on road trips with friends and incase I ever leave the city.

Cactus Jack 02 Mar 2017, 00:25

That Guy,

You have to wear glasses that are stronger than your final goal. Recall the equations

100 cm / 200 cm = 0.50.

To achieve that level you probably need to wear -2.50 glasses for some period of time. Inducing Myopia does not happen fast.

There are actually two types of Myopia. Axial or True Myopia is caused by excessive eyeball growth that takes a while to occur. It is "permanent" because once your eyeballs have grown a bit too long (approximately 0.3 mm per diopter) they don't shrink. Pseudo Myopia is caused by your Ciliary Muscles and Crystalline Lenses not fully relaxing. This happens very quickly, but is considered Temporary, but Temporary can be a long time if you continue to wear over correction.

At your age and if your genes will allow it, you may be able to Induce some Axial Myopia, but the first step is to Induce as much Pseudo Myopia as you can. You may be surprised at how much overcorrection you can manage, but it takes dedication and some effort on your part.

One thing you may discover is that you really like the crisp, vivid vision, being over corrected provides.

You did not answer my 2nd question about Driving. The questions are not meant to be nosy. Your answers help guide me to make applicable suggestions to help you achieve your goals.


That Guy 01 Mar 2017, 23:37

Cactus Jack,

I would like to roughly double that, so that I would go fuzzy after about 1.5 to 2 meters.

Cactus Jack 01 Mar 2017, 23:02

That Guy,

I forgot to say that your approximate glasses prescription would be:

Right Eye (OD) Sphere -0.25

Left Eye (OS) Sphere -0.25

You may have some Astigmatism which would be corrected by Cylinder and Axis in your glasses, but the simple test cannot detect it separately. That takes an Eye Exam.

For Inducing Myopia, you would Increase the Sphere (never the Cylinder or Axis) prescription by -1.00 or -2.00 diopters, initially and then keep increasing it as you become accustomed to wearing the stronger prescription. There are some "tricks" for doing this so that the increases are not particularly noticeable to others. We can help you with those.


Cactus Jack 01 Mar 2017, 22:55

That Guy,

Very readable, but just getting the faintest fuzz you can detect on the edges of the letters.

If you had "normal" vision, it should have been about 100 cm (1 meter). I forgot to ask if you had any Physics or Math in school, but all you need is some simple Math to understand the basics of Optics.

The most fundamental equation in Optics is

Focal Distance = 100 cm / Lens Power in Diopters

or its re-arrangement

Lens Power = 100 cm / Focal Distance

100 / 86 = 1.16 and 100 / 79 = 1.26

Based on those numbers, you are just a little bit Myopic or Nearsighted or Shortsighted, different names for the same thing.

Corrective lenses have the reverse sign of your actual Refractive Error. Based on these numbers, your Refractive error is about +0.25 in each eye.

100 cm / 0.25 = 400 cm or 4 meters

What that means in practical terms is, that you do not see clearly beyond 4 meters.

Vision actually occurs in the brain, your eyes are merely biological cameras. You brain has amazing image processing capabilities and it can correct vision to some extent IF your brain know what something is supposed to look like.

There can be a secondary factor in seeing clearly in bright light conditions. Your Pupils act like the Iris in a professional camera lens. If the Pupil or Iris opening is small, as in bright light, the "Depth of Field" or "Range of Useful Focus" increases and that helps you focus. In dim light and at night your Pupils open up and you may notice that distant signs are hard to read. Stars in the night sky may not be pinpoints of light or even invisible if they are not exceptionally bright.

You may find yourself squinting to see distant things like Menu Boards clearly.

The ideal thing would be to get an Eye Exam to find out your actual prescription, but we have almost enough information to order some glasses online. All you need to order online is a credit card, a prescription (doesn't have to be an official one) and your Pupillary Distance (PD). We can tell you how to measure your PD.

You will also need to have some place for the glasses to be sent.

Some more questions:

1. What would you like to do? Don't do anything until we chat some more.

2. Do you drive?

If there is Myopia in your family, it will be easier for them to understand that you need an eye exam, but you need to be careful about the symptoms of needing one.


That Guy 01 Mar 2017, 21:49

Cactus Jack,

Using +1 OTC glasses (sorry about the strength but they were free) I got 86cm in the right eye and 79cm in the left.

How fuzzy were the words supposed to be? You said edge of the letters so I assumed the words were still ment to be readable.

Cactus Jack 01 Mar 2017, 20:25

That Guy,

I would like to suggest that you get an eye exam, but before you do, I suggest you do the following "Home Refraction Test".


The purpose of this test to get an idea of a person’ refractive error. It works best for a person who is mildly Myopic or Hyperopic. It does not test for Astigmatism, which can affect the results. It uses the most fundamental laws of Optics as codified by Sir Isaac Newton, over 300 years ago.

1. You will probably need some Over-the-Counter ()TC) +1.50 or + 1.75 reading glasses. Other known power reading glasses can be used, but they SHOULD NOT have any Astigmatism (Cylinder) correction.

The purpose of the Reading Glasses is to cause Artificial “Optical” Myopia that brings the relaxed “Distance” focus into a useful range of less than an Arm’s Length range of 50 to 65 cm (20 to 25 inches). You will see why in a moment.

2. A book or newspaper (the Target) with normal sized print.

3. A tape measure calibrated in cm, (preferable) or inches.

The test is done with each eye individually while wearing the OTC Reading Glasses in there morning whee your are well rested and have not done much close work. If you wear glasses for distance vision you should wear the OTC glasses OVER your regular glasses.

Test Procedure starting with the Right Eye.:

Step 1. In good but not BRIGHT light hold the Target close enough so that the text is very legible.

Step 2. Move the Target away from your eyes until the text just begins to be fuzzy around the edges of the letters.

Step 3. Measure the distance from your eyes to the Target and make note of the distance.

Step 4. Repeat Step 2 and 3, 3 times and average the distance.

Step 5. Repeat the test with your Left Eye..

Let me know the distances you obtained and the test conditions, including the power of the OTC glasses. I will do some calculations and report back to you. Typically, with suggestions of what you should tell the Eye Care Professional prior to an exam.

I will also post "HOW TO STUDY FOR AN EYE EXAM" if I suggest an Eye Exam is appropriate.


Soundmanpt 01 Mar 2017, 15:37


Old age isn't a good thing. I am really sorry about that. I seem to be using the excuse more and more with my friends "another senior moment"

As long as your eyes are comfortable wearing even stronger glasses that's fine to do but sadly for you I think you're age is against you, once your past 20 it's nearly impossible to induce much myopia no matter how strong you go. Your eyes are simply refusing to be changed. But ordering glasses on line is cheap and getting new glasses should at least get you some nice complements.

Kiki057 01 Mar 2017, 14:28


I posted about my exam on 2/16 and you responded the following day, lol. I may just order another pair of glasses that are slightly stronger and wait until next year for another exam.

That Guy 01 Mar 2017, 13:23

Cactus Jack,


2.Yes but not since I was 6.


I do have a massive family history of myopia though also my left eye tends to do slightly worse then my right in eye tests.

Cactus Jack 01 Mar 2017, 09:42

That Guy,

At 17, you probably can Induce some Myopia. A few questions:

1. Do you presently wear any vision correction?

2. If not, have you ever had an eye exam?

3. Where do you live?

The starting point for inducing Myopia is your having an idea of any current refractive error.


That Guy 01 Mar 2017, 08:15

Hey sorry if I seem lazy but there's just so many posts.

Im 17 how could I induce myopia?


antonio 28 Feb 2017, 23:59


if you want to wear a real pair of glasses for driving at night or driving in General clearing up your starting far fogs just order an ordinary -0.5 pair and not cylindrical ones. I.m pretty sure your eyes liked the feeling of being supported by -0.5 spherical , but not only in one axis as cylindrical lenses do for your friend.

Best regards and much fun becoming slowly a real gwg,


Soundmanpt 28 Feb 2017, 14:13


Okay Cactus Jack explained to you why an optometrists will often ignore an astigmatism if it is less than -.25 of contacts. If it is -.50 or more then the optometrists will often add an extra -.25 to the SPH for contacts. If the astigmatism is over -.50 then the optometrists will prescribe toric lenses which like Cactus jack stated is quite a good bit more expensive. And of course for glasses the optometrists will of course include the full prescription including the CYL and axis. Now you mentioned trying on a friend's glasses which contained -.50 CYL and 165 both eyes. Now just trying her glasses on for several minutes you're eyes probably weren't effected by the astigmatism correction, but if you were to wear her glasses for a longer time you most likely would have started to feel a headache coming on. At first your eyes would be able to ignore the astigmatisms in her glasses but as your eyes adjusted to her glasses then you would start to notice it in a bad way. Adding CYL to your glasses isn't going to help in your effort to induce myopia.

You didn't post the outcome of your eye exam form the other day? I know you said that 3 years ago when you had your eyes examined you were +.75 / +.50. But that was before you started wearing -4.00 glasses and contacts.

Cactus Jack 27 Feb 2017, 17:35


They make Toric contact lenses for Astigmatism, but they are expensive, compared to sphere only CLs, and hard to fit. They also can move around on the Cornea which makes vision variable. Often, with low levels of astigmatism they fit a Sphere only contact lens. The rule is the Sphere Only contact should have 1/2 the Cylinder algebraically added to the Sphere. That means that the Sphere Only contact is a compromise, but if the Cylinder is not too high, it works acceptably well.


Kiki057 27 Feb 2017, 16:23

I have a question about possibly order glasses from Zenni and I know that I have posted on this thread before so hopefully it's ok. If someone is given a glasses prescription with astigmatism why is it not reflected on the the prescription for contacts? If it's just slight correction for astigmatism maybe it's not needed for contacts? Basically I tried my friend's glasses on and her astigmatism is

OD Cylinder -50, Axis 165

OS Cylinder -50, Axis 165

Not sure if that helps but I might order a pair of glasses with the astigmatism correction in so I wanted a few opinions from my fellow glasses lovers

antonio 17 Feb 2017, 10:35

Hi Kiki,

AS you describe it, it's clear to me , you might be already mildly shortsighted.

I guess sooner vor later you will get a real minus prescription you really need for driving especially at night.

Do you want that?

Are you female, so you integrate your glasses into your Outfit as a nice accessoire when you wear them?

How do your friends react when you wear glasses as strong AS -4 and you remove them for driving ? :-)

Best regards and god luck, antonio-o

Hope to See you in

Soundmanpt 17 Feb 2017, 10:08


I know that you're disappointed that you didn't come away with an actual prescription for minus glasses but like you say it does appear that wearing glasses and contacts has at least resulted in a small change. And remember it's not like the doctor is taking your glasses and contacts away from you. So as long as you enjoy wearing your glasses and you apparently have good vision wearing them then just continue wearing your glasses just as you have been. When you first take off your glasses how long does it take before you're natural eyesight returns to you? I'm sure when you first take your glasses off things are very blurry so you know that when you're wearing your glasses your eyes are using the prescription of your glasses to see clearly. So the main difference is that your eyes don't remain constantly blurry without your glasses and that of course is what you would like to start happening.

Kiki057 16 Feb 2017, 16:56

Well that was the biggest let down ever!!! The eye doctor says my eyes are perfect but I think I'm going to get a 2nd opinion cuz when I just use one eye at time, especially at night it's pretty blurry. The last time I had my eyes tested 3 years ago I was given trial contacts for I believe +.75 and +.50 so maybe I really am going in the right direction?

antonio 15 Feb 2017, 14:54

Sorry at

antonio 15 Feb 2017, 14:53

Hi Kiki

Will you go there without wearing any glasses?

I guess you could get your first real prescription out of it for driving. Good luck. Best regards Antonio. If you like, discuss with us in

Have you gone for your eye exam yet?

Cactus Jack 13 Feb 2017, 08:26


One thing I forgot to mention in "How to Study" is the Red/Green test.

Near the end of the exam, you may (it is optional) be shown a chart where half the chart has a Red filter and the other half, a Green filter. This is a final check of your Sphere correction. Here is the rule: If the letters on the Red side are clearer than the letters on the Green side, you need MORE minus. If the letters on the Green side are clearer you need LESS minus.

The test is based on the principle of Optical Physics that Red light and Green light have different focus points because of their different wavelengths. The test has nothing to do with color perception and the test works even for people who are color blind.

If you do not have color perception problems and you are offered the test, you can usually get another -0.25 in your prescription by saying that the Red is clearer, but don't push it too far beyond, "equally clear". One step is generally OK, but two steps is the absolute maximum.

If you can schedule the exam late in the day, try to read a lot before the exam and in the waiting room.

Not everything, but perhaps enough to get an accurate exam. Have you decided if you will wear your sisters glasses or what visual complaints you will report? Myopia typically causes:

Inability to read see the board or screen at the front of the lecture hall or classroom.

Poor low light or night vision.

Blurry distant signs.

Difficulty reading menu boards.

Can't see distant things as well as your friends can.

Myopia typically does NOT cause:

Headaches when reading.

Close focusing problems.

Problems reading small text on phones or tablets.

Unless there is significant Astigmatism present.

Thank you so i understand everything about the eye exam. I will go next saturday.and i will tell you the results.

Cactus Jack 12 Feb 2017, 17:24


Here it is.


An eye exam is not like an exam that you might take in school and there is really no way to study for it. However, you can prepare for it and learn about your role in the exam. The best eye exams are a team effort between you and the Examiner. Part of the preparation is to learn what to expect, particularly if this is your first eye exam.

One important thing you need to keep in mind is that the Examiner has no way to experience what you are seeing. He/she has to depend on your answers to questions.

There are two parts to an eye exam. The first part is the Objective part. This part consists of:

1. Taking a Visual History where you describe your vision and the kinds of problems you are having.

2. Checking the internal pressure in your eyes for symptoms of Glaucoma. This is one of the very few parts of an eye exam that is even mildly uncomfortable and the discomfort only lasts for a few seconds. There are two basic ways to do the pressure test.

A. Using a special instrument to lightly touch your Cornea. Not to worry here. Before doing this type of test a drop of mild anesthetic will make sure you don’t even feel it.

B. There is a new type instrument that uses a puff of air directed against your cornea. No anesthetic is required, but the puff will startle you. The puff of air is harmless and there are huge benefits. Detecting Glaucoma early, before it can do damage can save your eyesight.

3. The examiner will also get a preliminary estimate of your refractive error by using an Auto-Refractor or manually by using a small hand held instrument called an Ophthalmoscope or Retinoscope.

The Auto-Refractor is a relatively new instrument that was developed in conjunction with NASA to check Astronauts vision in space. You look into the machine with each eye individually where you will see a scene or a pattern. The machine will adjust its internal lenses to focus the image you see on your retina. The Auto-Refractor only takes a few seconds for each eye and it then prints out your estimated prescription.

Some Examiners prefer to use manual methods that have been used for many years. Using an Ophthalmoscope or Retinoscope and a Trial Lens set or a Phoropter (a fancy machine with a built in lens set), the Examiner will look into your eyes and select the lenses that allow him to see your retina, most clearly.

The object of this part of the exam is to get a starting place for the Subjective part of the exam where you have to describe what you see.

Typically the Subjective part of the exam starts with the Right Eye shutter open and the Left Eye shutter closed.

Step 1 is typically determining the cylinder and axis of any Astigmatism correction you need. This is actually the hardest part of the exam because you will be asked to judge relative blurriness of two images rather than the sharpness of an image.

You will be shown a line of text and a supplemental lens will be rotated into place. This lens is a cylinder lens that is mounted on a 45 degree pivot and can be flopped back an forth to bracket a trial axis or orientation of the long axis of the cylinder lens. The thing that is confusing about this test is that the straight lines (strokes) of the letters will alternate in clarity as the lens is flipped back and forth depending on their direction. I suggest concentrating on an “O” if possible. Depending on your answers, the examiner will adjust the axis knob unit the image you see is equally blurry with the supplemental lens 45 degrees each side of the selected axis.

At this point the Examiner will probably swing the supplemental lens out of the way and may change the cylinder power while asking you which lens in clearer.

For your first exam, you may be uncomfortable asking the Examiner to let you fine tune the Cylinder Axis, but I have found that most will appreciate your wanting to actively participate. The way that works is that he will place your hand on the Axis control knob. This time, you move it back and forth a few degrees looking for the sharpest image. It is a bit like “Fine Tuning” an old Analog TV set or moving the tuning knob on an analog AM radio for the best signal.

The next step is determining the Sphere correction. This is an easy part of the exam because all you have to do is pick the sharpest image, but there is a tricky part. Your auto-focus mechanism will try to help, if it gets a chance. The Examiner has a couple of ways to minimize the action of your ciliary muscles and crystalline lenses.

The Examiner can, in effect, sneak up on your Sphere prescription or he can use drops to Dilate your eyes. Lets talk about sneaking up on your prescription first. There are actually 4 lenses in your eye’s lens system. All of them are PLUS lenses and the total power is about +56 to +60 diopters. The only variable focus lens is the crystalline lens whose PLUS power is controlled by your ciliary muscles. For distance, your Crystalline lens is fully relaxed and has somewhere around +15 diopters. When you focus to read, your Ciliary Muscles squeeze the Crystalline lens to increase its PLUS power by the amount necessary to focus which depends on the distance to the object.

This will take a little thought to get your mind around, but if you are nearsighted, your lens system has too much PLUS for the distance from the lens system to your retina and you need MINUS lenses to neutralize some of that excess PLUS power. You ONLY have the ability to increase the PLUS power of your lens system. You have NO ability to reduce the PLUS power of your Crystalline lenses more that fully relaxed.

To try to keep your Ciliary Muscles and Crystalline lenses from getting in the act, the examiner will start with NOT ENOUGH MINUS or TOO MUCH PLUS (same thing) and gradually increase the MINUS one or two steps at a time, while reducing the size of the line you are asked to read. He will not tell you what power lens or what line you are looking at. Eventually, he will reach the 20/20 line and a lens power that lets you read it with no mistakes.

He will then follow the same procedure with your Left Eye.

When he has completed both eyes, he will open the shutters and you may see two images. This part of the test is to check your muscle balance using some prisms. He will probably ask you to tell him when the two images are aligned horizontally and then vertically. While the images are separated, you have an important check to make. Compare the sharpness of the two images. If they are not equally sharp, be sure and tell the Examiner which image is clearer. If there is a difference, he will likely reduce the sharpness of the clearest image until they match. The important thing at this point is that they match. That lack of sharpness will be corrected in the next phase with both eyes working together.

Next he will fuse the images so both eyes are working together and repeat the Sphere procedure by gradually increasing the MINUS or decreasing the PLUS until you see the smallest line of letters very clearly.

That pretty much completes the exam except for checking your near vision with a small chart about 14 to 16 inches from you.

Many people, who wear glasses, actually look forward to eye exams. Once you have become accustomed to having very good vision, you will probably find anything less, unacceptable. Many times, after the exam, it will be suggested that you get another exam some time in the future. Note that I used the word “suggested”. it is NOT a Command. If your detect a problem or if your vision seems uncomfortable, please don’t wait until the “suggested” date to seek an appointment to get your vision checked.

Let me know if you don't understand anything.

Where can i find your article "How to study for an eye exam "?

kenpachi 12 Feb 2017, 14:36

Cactus Jack

My vision fits perfectly with my sister's old glasses. I will get an eye exam soon and I will tell you the results. I will tell the examiner that i have trouble reading road signs and seeing the white board in school.And i will find the glasses -1.75 .-1.50 on the websites you provided me last night .

Cactus Jack 12 Feb 2017, 13:45


If you get an eye exam, I suggest you read "How to Study for an Eye Exam" which I wrote a few years ago.


Cactus Jack 12 Feb 2017, 13:42


Both tests show that you are a bit myopic. The second post with the +2.00 glasses revealed the following:

Right Eye (OD) 100/39 = +2.56

Left Eye (OS) 100/37 = +2.70

If you had no Myopia, the fuzziness would have occurred at 50 cm 100/50 = +2.00. Because the fuzziness occurred at 39 ad 37 cm, it means that your eyes were supplying additional PLUS, which is what happens in Myopia. If you had an eye exam, the prescription would probably have been pretty close to:

OD Sphere -0.50

OS Sphere -0.75

The problem with the test is that it cannot reveal if you have any Astigmatism.

There are some online tests for Astigmatism, but all they can tell you is that you have some or not, but they can't give you any idea of the actual values. Astigmatism is corrected by Cylinder and Axis numbers in the prescription. You have to have an eye exam to get those numbers.

One of the most important principles of Inducing Myopia is that you ONLY increase the Sphere and NEVER modify the Cylinder and Axis numbers from your actual prescription. Also, you ALWAYS increase both eyes by the same amount.

It would be best if you started with an eye exam, but we have enough information for you to get started.

I suggest you order some glasses with this prescription.

OD Sphere -1.50

OS Sphere -1.75

An increase of -1.00 in each eye.

When you get comfortable with those, you can order:

OD Sphere -2.50

OS Sphere -2.75

If you decide to get an eye exam, either do not wear any glasses or if not too obvious, you can wear your sisters old glasses. You need to explain to the examiner that you are having trouble seeing the board in class and have been wearing your sisters glasses because they help. If you get a prescription, don't get it filled, if you can avoid it, and let me know what it is.

I did another test which i think we should count on it because i used my calculus book. The test I did before i wasn't very accurate and the book's text wasn't small like the calculus book.the results is :

39 cm right eye . 37 cm left eye .

With +2.00 power lense . I did it 4 times and the results were the same.

kenpachi 12 Feb 2017, 02:09

Cactus Jack

Hello,I did the test with a 2.00+ power lenses.The text became fuzzy when the distance was 45 cm right eye . 43 cm left eye. The text wasn't too small nor too big . The P letter was 5 mm . And my mother language is arabic.

Cactus Jack 11 Feb 2017, 18:35


The second formula should be:

100cm/ focal distance = lens power in diopters

BTW, I am not an Eye Care Professional (ECP). My background is Electronic Engineering and Computers. I learned basic optics in Physics and learned about vision on my own, trying to understand my own vision problems.


Cactus Jack 11 Feb 2017, 18:31


Your English is fine.

It would be OK to do the test now and then do it again in the morning to see if there is any difference.

The formula for focal distance was codified by Sir Isaac Newton about 300 years ago. it is:

100 cm/lens power in diopters = focal distance


100cm ' focal distance = lens power in diopters.

The +1.50 or +1.75 reading glasses will make the focal distance about right for easy measurement. If the glasses are too strong, the text will get fuzzy much closer to your eyes and smaller distance errors will make a big difference in the accuracy of the results. It is OK to do the test with any reasonable power reading glasses, but please let me know the power or the prescription if possible.

Hopefully the reading glasses DO NOT have Cylinder correction. It will affect the results.

What language is spoken in Iraq?


kenpachi 11 Feb 2017, 16:29

By without perception i meant without going to the eye doctor .

I have a high degree at maths and physics also i am going

electrical engineering ,I live in Iraq,Baghdad,and the last time i did an eye test was 2 years ago and it was 0.00, yes i can order but it will take too long,can i buy them from drug stores without a perception?also there is a reading glasses in our house.Can i do the eye test now ? or tomorrow when i wake up in the morning ? because i did so much close work for today. I will ask my parents about what power the reading glasses is, and excuse me I am not good at English.

Cactus Jack 11 Feb 2017, 16:09


I see that Soundmanpt has also responded. We work together a lot, but have different styles. Our objectives are the same.


Cactus Jack 11 Feb 2017, 16:06


You have the right idea, but you need to be much more aggressive. You need to get higher and wear them all the time. The more close work you are doing the better.

The ideal place to start is with your actual prescription (refractive error). Even if you do not presently wear glasses or if your refractive error is 0.00, we need to know what it is, as a starting place. More about that later.

There are actually two types of Myopia. Axial or True Myopia, which is considered permanent, is caused by a mismatch between the total PLUS power of the eye's lens system and the length of the eyeball. The distance from the back of the Crystalline Lens to your Retina. The eyeballs of people with Axial Myopia, grew a bit longer than they should have by about 0.3 mm per diopter. Genes play the biggest role in Myopia and the visual environment plays a secondary role. Pseudo or False Myopia is considered temporary, but sometimes temporary can be a long time. It is caused by the Ciliary Muscles and Crystalline Lenses, your auto-focus system, having trouble fully relaxing after focusing close for a long time.

The idea behind Inducing Myopia is that you force your Ciliary Muscles and Crystalline Lenses to focus close as much and as long as possible by wearing glasses or contacts that have much more MINUS than you actually need. At 18, you have significant accommodation range, but your Ciliary Muscles may not be strong enough to be able use it all. When you were born, your clear protein of your Crystalline Lenses had the consistency of freshly made gelatin dessert. As you get older the protein gradually becomes stiffer and at some point you will need external focusing help, usually around 40, but not always. The condition is called Presbyopia (old eyes) and it can occur at any age. People who are farsighted are particularly vulnerable. That is why you sometimes see teens with bifocals to be able to read text on their smartphone.

Initially, you can pretty easily Induce some Pseudo Myopia and if you are lucky and are not too old and your genes will permit it, some of that Pseudo Myopia will turn into Axial Myopia.

I have a few questions and a simple test you can do to check for any Sphere refractive error. Unfortunately, there is no simple Astigmatism test you can do at home.

1. What is your occupation?

2. If you are still in school, what grade or level and the highest math or physics you have studied? That helps me determine how technical I can get in my explanations.

3. Where do you live? Country and city size over time you may need to see different Eye Care Professionals (ECPs) for progress checks.

4. Can you order and confidentially receive packages? With stronger and stronger glasses?

We will tell you what you need to order and how to do it once we have figured out where you are. Also, we will tell you what to say when you get an exam.

Here is the simple refractive test. You will need a pair of +1.50 or +1.75 Over the counter (OTC) reading glasses, a tape measure, and a book or newspaper. The reading glasses are to create artificial Myopia and move your focus distance into an easily measured range.

Pick a time when you are well rested and have not been doing any close work. You will do one eye at a time. In good, but not BRIGHT light, while wearing the OTC glasses, hold the book or paper where the small text is clear and easily readable.

1. Gradually move the book or paper away from your face until the edges of the text letters just becomes a bit fuzzy around the individual letters. Measure that distance an make a note of it.

2. Do Step 1, 3 times and average the distance.

3. Do steps 1 and 2 for the other eye.

4. Tell me the distance for each eye

5. Tell me the results and what power glasses you were using.

I will calculate your refractive error and suggest a plan.

Please do not buy anything other than the OTC glasses.

I suggest you also check out the Zenni Optical web site. They offer inexpensive, high quality glasses for a low as US$6.95. The frame and lens selection control the cost. Some glasses you will only wear for a month or so before changing to a stronger prescription. The trick when changing prescriptions is to use the same frame style. Few people notice prescription changes, but they do notice frame changes.

Also, download and read this article about the eyes and how they work. It will help your understanding.


kenpachi 11 Feb 2017, 15:53

Your sister's old glasses are probably a little weaker than you want to be wearing. You're young and your eyes should be more than able to tolerate a little bit stronger glasses without any problem. I would suggest that you go on line to someplace such as "" or "" and order at least 2 pairs of glasses using the exact same frame number for both. Get one with -1.00 lenses and the other with -1.75 lenses. Once they arrive start off by wearing the -1.00 glasses completely full time, not just for certain things but everything. If you want to have any hope of ever needing -5.00 glasses you need to put on those -1.00 glasses as soon soon as you open your eyes each day and not tale them off again until you're going to bed that night. After your eye have completely gotten used to wearing the -1.00 glasses and everything is perfectly clear with them, then you need to start wearing the stronger ones. By using the same frame no one will notice that you're wearing the stronger glasses. Needless to say you don't really want to many questions being asked. What you're wanting to do will take a lot of commitment on your part. So you have to be sure this is what you want.

kenpachi 11 Feb 2017, 13:59

Hello everyone, I am 18 and i would like to be nearsighted, my parents are both myopic, but unfortunately for me that i am not, my sister is also myopic,I started using her old glasses ,It is maybe left -0.50 right -0.75, if i want to be -5.00 or more,should i wear those or get higher? most of my time is in front the computer,gaming ,should i wear them when i use my pc or reading? thank you

antonio 08 Feb 2017, 15:23

Hi Kiki057,

regarding you mentioned you See slightly blurried far Ehen driving Ehen looking far and closing one eye. That could Jean you Start to be really in need for at least a weak prescription for at least one oft your eyes for driving, perhaps even for both already. Your brain always shows to you the best image possible out oft what your eyes - biological cameras deliver to him as rawdata. It.s normal one Sees sligtly sharper with 2 eyes than with one as your braun eliminates bluriness vor sharpens your image by comparing computationally two slightly blurred images from your eyes. Vor simply one oft your eyes Sees better, then this image is shown to you whatever this eye can See. Hope that helps and looking forward to your eyetest. I.m shortsighted besides and my eyes behave somewhat similar to your :-).

Best regards, Antonio. See you in, if you like to discuss about vision,...

Soundmanpt 08 Feb 2017, 13:37


First of all as for as if the ECP would be able to tell that you had been wearing contacts I don't think he or she would be able to tell but even if you asked, which I really doubt, you simply say that you often wear some non-prescription colored contacts that you bought on line.

I saw what Bob commented and I do understand that like him you may want that feeling of being justified knowing that you actually do need glasses or contacts and I truly hope that you get a real prescription for glasses that will make you happy, but if that doesn't happen you at least still don't have to give up and stop wearing glasses. But at some point you;re going to have to slowly start wearing some of your weaker glasses maybe along with a pair of weaker contacts that equal out close to what your eyes are currently used to. Right now you're leading 2 lives when your friends and co-workers see you wearing glasses full time and your family thinks you don't need glasses. That can be dangerous if you're out with family and come across a friend or someone from work. The risk of getting caught is out there for sure. I look forward to hear the results of your eye exam.

Kiki057 08 Feb 2017, 08:23

Will the eye doctor be able to tell if I has wearing contacts up until my appointment?

Kiki057 08 Feb 2017, 07:58

To explain a little more, I have been able to wear my R: -4.25 and L: -4.75 freely at work and at home. All of my friends and coworkers assume that I actually need them. If I'm going to be around family I wear my contacts but can't wear my glasses. I am planning to schedule an eye exam soon and will let you guys know what I find out!

Bob 08 Feb 2017, 04:36

soundmanpt, Kiki057

Even though the prescription may be below the -4.0 that Kiki057 currently wears, I can retrace the desire to get an acknowledgment that you are now myopic, even if your desire to wear glasses is a private affair, and even though you may just continue wearing your strong glasses anyway.

I had the desire to become glasses wearer myself since I was young, and eventually got a prescription similar to your original one (low plus). I wore this immediately full time, but was frequently disappointed by my ECP who only suggested (and assumed) part-time wear since the prescription was relatively weak. Only a few years later I experienced a steady increase in astigmatism (and moderate increase in hyperopia). I still recall the sensation when my ECP suggested that part-time wear would no longer be an option, and I got a condition on my renewed drivers license since I was no longer allowed to drive without correction (even though I hadn't done so in years anyway).

Anyway, this acknowledgment of my requirement for glasses felt rewarding, even though noone else knows about my true desire. But now wearing glasses is truly not an option anymore.

I am not sure if that reflects you sentiments, Kiki057, but that is why regular eye exams were (and still are) important to me. Anyway, if you like, it would be great to hear about your experience and result of your eye exam.

Soundmanpt 07 Feb 2017, 14:56


I remember you asking before and trying very hard to become myopic and without much success. I think the biggest thing you have working against you is the fact that your now 32 years old. Not old by most standards but for the eyes to be forced to change considerably too late. If you have been wearing on average -4.00 prescription in either glasses or contacts for several years whatever you get when you go for an eye exam is probably all you can expect. Going any stronger won't be of any help. If your eyes were going to be changed -4.00 is more than enough to make a difference. If your eyesight isn't being change or only changed slightly then it makes sense that even after wearing your -4.00 glasses all and taking them off that you are still able to see quite well without your glasses. But i'm not sure why if you cover one eye the vision in the other eye is more blurry and then the same if you revers it. As far as how to explain marks or dents on your nose caused by your glasses I would say if it is still daylight when you go then those marks could easily be caused by sunglasses.Also if you're female simply reapply makeup on your nose which every woman does quite often anyway. Of course when asked about glasses you say you lost them and you play dumb and have no idea what your glasses were for when you had them.

I know your goal is to be given a nice decent prescription for glasses but really what difference does it really make? Without any doubt even if you mange to get a prescription it won't be anywhere near -4.00. So if you were given a prescription for say -1.50 glasses what would that really mean for you. Your eyes apparently are doing and seeing very well wearing a much higher prescription so I doubt that you would run out and buy -1.50 glasses anyway. You apparently are completely happy with wearing either contacts or glasses that are at least -4.00 and you wear them all day long at your computer at work and you wear them for driving without any problem. So what's more important, having a piece of paper that says you need glasses or wearing glasses like you're already doing? Your the only one that knows that your still able to see quite well without glasses so everyone you know thinks you can't see very well. What they don't know is your little secret.

Kiki057 07 Feb 2017, 11:37

So I've posted here before and am hoping to get some answers. For the last few years I have been wearing glasses or contacts with an average of -4 in each eye. I work on a computer all day so I thought maybe that would help the process. 3 years ago I had my eyes tested and my RX was +.75 and +.50. I've been obsessed with glasses since I was a little kid. Now that I'm 32 and living alone I can wear them all the time without anyone questioning me. So I plan to make an eye appointment but I have some questions. I rocked Anatomy in high school but I don't remember everything about how the eyes work. So when I'm driving home and take my glasses off I can see pretty well but if I close one eye at a time it's blurry. Why is it that looking out of one eye at a time it's blurry but when they are working together it's barely noticeable. If I go to the eye doctor right after work I will have the dents on my nose from my glasses but if I wear my contacts right up until I walk into my appointment will the doctor be able to tell that I've had contacts in? I hope this all makes sense and I appreciate any feedback!

Cactus Jack 17 Jan 2017, 23:44


Yes, reading and close work with your glasses or contacts help the process. Normally, the Ciliary Muscles and Crystalline Lenses are fully relaxed with the minimum Plus power for distance. However, your Crystalline Lenses are NOT at Zero Power when fully relaxed. They are probably around +16 or so. If your distance vision is or is corrected to 0.00, your Ciliary Muscles squeeze your Crystalline Lenses to increase their PLUS power to focus closer than technically "infinity", but for practical purposes 20 feet of 6 meters. The amount of increase is determined by the laws of Optical Physics as codified by Sir Isaac Newton bit over 300 years ago.

In your situation, when you wear more MINUS than you actually need, your Ciliary Muscles squeeze your Crystalline Lenses and add enough PLUS to compensate for the excess MINUS in your contacts or glasses. Then when you read or focus closer than 20 feet or 6 meters, your Ciliary Muscles squeeze some more to enable you to focus close with your contacts or glasses.

If you have ever done any photography, you will understand the similarity between the pupils of your eyes and the Iris in a camera lens. Both control the amount of light striking the Retina, Film or Digital Sensor. In low light both are opened up, in bright light both are closed down to reduce the size of the aperture to control the light. There is a secondary optical effect of closing down or opening up the aperture. It changes the depth of field or range of useful focus. If you are in bright light and close down the aperture enough, everything from near to far will be in focus. If you open up the apertures to maximum in low light only those objects that are near the exact focus distance will be in focus.

When you do the refraction test, try not to do it in very bright light. It will give you truer readings.

You might find this paper informative about how your eyes work. I think you will be surprised.

Two important things to remember: 1. keep the pressure on was much as possible and 2. Nothing happens fast.

One other thing, I don't think you need to consider Gas Permeable Hard Contacts. I don't think you have enough Astigmatism to justify the hassle and expense.

May I invite you to contact me at


Zack 17 Jan 2017, 19:58

Cactus Jack,

Yes that was without glasses or contacts. I am happy I am making any sort of progress even if minute.

I see what you are saying about the eye, I didn't really know that much about astigmatism before now but it makes sense to me now, it's pretty interesting.

I wear soft contact lenses and they are sphere only. They did not bump my prescription up because of my astigmatism as my contacts prescription is currently -2.5, which is the same as the sphere value of my left eye.

Tomorrow after wearing my -6 contacts to my classes, I will test myself again right after I take my contacts out.

Also will reading books and my computer while really close (with my glasses or contacts on of course) help with the process at all? That's what I have been doing and I feel like it is helping but I am not 100% sure.

Thanks again!


Cactus Jack 17 Jan 2017, 19:19


Was that without contacts or glasses? It seems like you are making some progress. Your astigmatism confuses the issue a little because without correction, you are

OD -2.25 in the 25 degree Axis and -2.75 in the 115 degree Axis

OS -2.50 in the 180 degree Axis (Horizontal) and -3.00 in the 90 degree Axis

I know that sounds weird, but Axis direction is the Long Axis of - Cylinder. Think of the shape of your Cornea as a section from he side of an American Football. The Long Axis has a very shallow curve and the Short Axis is at a right angle (90 degrees) to the Long Axis is steeper and therefore has a bit more Plus power than than in the Long Axis.

You may have to read that and think about it for a bit and recall that corrective lenses neutralize or cancel out actual refractive errors.

Do you normally wear Toric Contact Lenses or Sphere only? For mild Astigmatism, 1/2 the Cylinder is often algebraically added to the Sphere and Sphere only Contacts are prescribed. That usually gives satisfactory vision and avoids the cost and hassle of getting Toric Contacts to stay correctly oriented on the Cornea.

I would like to ask you to do the test again after you have worn your -6 contacts for an extended period, Immediately after you take your contacts out.

Don't get discouraged if it is about the same or just a little closer. I will explain why after your report.

Cactus Jack,

My last prescription from last August was

OD -2.25 Cyl -.5 Axis 025,

OS -2.5 Cyl -.5 Axis 180.

My vision was kind of fuzzy after my last examination because my ECP decided to not bump up my prescription anymore because the 20/20 line she showed me was blurry but just visible enough that I could read it. I should have spoken up in hindsight and said that it was not good.

In the past few years my cyl values have stayed the same and have not changed. Only the sphere values have changed.

I have completed the test,

For my right eye (OD), I got the numbers 33 cm, 33 cm, 33 cm, which averaged out to 33.

Then I took it and divided 100 cm / 33 cm and got 3.03.

For my left eye (OS), I got the numbers 30 cm, 31 cm, and 29 cm, which averaged out to 30 cm.

Then I took it and divided 100 cm / 30 cm and got 3.33.

I just woke up because I was tired so I was not awake for more than 10 or so minutes before taking this test.

Cactus Jack 17 Jan 2017, 15:53


I really need your last complete prescription before suggesting a strategy. I am particularly interested in any Cylinder and Axis numbers for correcting Astigmatism.

There is a very simple test you can do to get an approximate indication of your refractive error. You will need a book or newspaper (target) with normal sized print, a tape measure, and you may need some OTC reading glasses to get the distances involved into a useful range. This test can be done at any time of day, but it may be more indicative of your true prescription if done first thing in the morning BEFORE you put on glasses or insert contacts.

1. Hold the target at a distance where you can see the text clearly. Close one eye.

2. Gradually move the target away from you face until the text just becomes fuzzy.

3. Measure the distance.

4. Do steps 1 thru 3, three times and average the distance for each eye individually.

5. Divide the average distance into 1 meter (100 cm or 39.37 inches).

Note: If the distance is inconveniently far for the length of your arms, you can create some artificial Myopia by using OTC Plus Reading glasses. You want to use the minimum Plus to get the blur point distance to about 50 to 66 cm or 20 to 26 inches. You will need to adjust the calculated prescription for the supplemental Plus.

If you don't understand how the test works or need help, let me know and also let me know the numbers you get.

The result is inverse of your approximate prescription. Here is an example of how it works. Lets say that you do the above test and the text gets fuzzy at 20 inches (50 cm). Sir Isaac Newton's formula for calculating lens power vs focal distance is 1 meter / Focal Distance = Lens Power in Diopters. 39.39/ 20 inches = 1.96 or +2.00. That is your refractive error. The corrective lenses would be -2.00.

If you need to move the blur point outward you can do the test with low power minus glasses. You might try the test with low power contacts or glasses.

I need some of the above test results before I can help you develop an exam strategy. In your situation, it is easy when you understand the principles.


Zack 17 Jan 2017, 06:23

Cactus Jack,

You suggested that I create a strategy for my next eye exam,

How long should I wait or when should I decide on going in for another eye exam? My last one was in August.

Also are there any tips or tricks I should know before going into an exam?

I would also like to ask if there are any tests I could be doing to check my progress and how often should I do these tests? I am interested in keeping track of my progression.

Thank you very much for your help,


Zack 16 Jan 2017, 15:29


Thank you for the information, I will look into those sites when I get home and see if they will ship to the US.


Iain 16 Jan 2017, 15:09


Usually Fluoroperm

Try lensway or lenscatalogue here in UK, not sure they post to US


Zack 16 Jan 2017, 14:50

Iain and Cactus Jack,

Thank you both for the encouraging words and for sharing your stories! It gives me hope that I can possibly induce or even wear high prescriptions full time.

I would preferably get up to -12 or maybe even more, but I set my main goal at -6 or -8 as I do not know how much I will truly be able to truly induce as it can be unpredictable and like Cactus said it is up to my genes.

Even if I do not induce to that high of a prescription, it would still be cool to wear any of those prescriptions full time.

I would like to try and buy some gas permeable contacts as my next pair because I have been reading up on them and they sound nice. Iain, do you have any brand you could recommend and also a website where I could get them from? I don't think the website I usually buy contacts from sells gas permeable contacts, and I am having trouble finding a website that sells gas permeable contacts without a prescription.

Thank you both so much!

Iain 16 Jan 2017, 14:12

Cactus Jack,

That's very encouraging about the guy you helped. Come Easter I will have increased my cls Rx by -12. Was he able to maintain his new vision? Do you think I will be able to continue beyond -12 cls? I would like to go as far as I can.

My future beyond uni is unclear. More study is a possibility but I want to travel as well. I will be 21 in August so wish to explore. Travelling will complicate my induced myopia regime. Is it better to continue with youth on my side?

Zack you are doing great. Cactus is very encouraging. How high do you wish to go? Gas permeable have suited me, I get a new Rx every four months. I think my eyes have adapted so well as they do not get a chance to be without correction.

Zack 16 Jan 2017, 11:47

Cactus Jack,

That's amazing! I could only hope to get to that point eventually, but I will have to work up to it overtime. I have -13 glasses and I have worn them a bit around the house and I could see well with them in bright light but not perfectly in dim light, also my eyes would defocus for a few seconds every half hour or so when I was wearing them.

And I forgot about that, I guess I have never thought of sleeping that way, I will still try to be as careful as possible and wear my contacts or glasses from waking up to going to sleep at night. I just want to have as much stress on my eyes as possible.

Is there anything else I should be doing to make sure my ciliary muscles become as strong as possible, like reading for a long period of time and getting real close to the page?

Cactus Jack 16 Jan 2017, 11:03

Zack and Iain,

A few minutes without your glasses or contacts won't make any difference in your efforts. Your Ciliary Muscles get to relax for several hours while you sleep. The key to Inducing Myopia is the strength of your Ciliary Muscles. For their size, they are normally the strongest muscles in the body. Your efforts just make them stronger. The young man I mentioned had to get occasional dilated exams to gauge his progress. His goal was to flunk the "official" mandatory military service eye exam where they used a very strong dilating agent. Probably Atropine. Most ECPs use dilating agents for "wet" exams that wear off in a few hours.


Cactus Jack 16 Jan 2017, 10:52

Zack and Iain,

Several years ago, I worked with a VERY highly motivated young man in his late 20s who needed to be substantially more myopic than he was (about -4). He ultimately was able to wear -20 glasses while studying to pass the TOEFL exam.

If you do the Vertex Distance math, -20 glasses are effectively -16 at the Cornea so he was able to focus to read with 12 diopters of over correction. Because of his age, it was mostly Pseudo Myopia with only a bit over -1 of additional Axial Myopia, but the important thing is that it worked for his purposes.

Because you started at a younger age, it is possible that you will develop more Axial Myopia, but your genes are in the "driver's seat". It does not really matter which type of Myopia you develop as long as you understand the difference and that Pseudo Myopia needs maintenance. Maintenance is more important when you are young because your Crystalline Lenses are still very flexible and your Ciliary Muscles will relax fairly quickly. However, the most important thing that happens is that your Ciliary Muscles get very strong and are able to deal with the additional minus in your glasses very quickly.


Zack 16 Jan 2017, 10:41


I have been very careful to not see without glasses or contacts too. Most of the time I take my contacts out in before a shower and immediately close my eyes. I don't open them until I am out and my contacts are back in.


Right now I use extended wear contacts (Pure Vision), do you think I should switch to gas permeable ones? I only have one more -6 contact and I just put in a new monthly pair today, so I need to buy more -6 contacts. If so, any suggestions on brands or where to get them?

Thank you both Cactus Jack and Iain.

Zack 16 Jan 2017, 10:16

Cactus Jack,

Sounds like a plan, I will stay with my -6 contacts until the blur is completely gone in the dark, and then I will begin to move up in increments like Iain. Other than the small blur in the dark (things like the time on my phone are a bit fuzzy when the screen is dim) my vision is really good with these contacts and glasses. After the blur is gone, I will move to -7 contacts and -7.75 glasses.

1. I live in New York and I live off campus in my own apartment away from my family.

2. My favorite subjects are history and science, however I am in school for Computers as the subject also interests me.

3. My last eye exam was in August.

I work and therefore I have the money to go in for eye exams whenever I want as I have a pretty good amount of expendable income.

My ECP is back at home which I am only at during the summer and holidays, and therefore I have not gone to an eye doctor here at school and I have many doctors to choose from.


That's very cool, I would like to be able to build up wearing stronger glasses to my family so they notice my vision getting worse so it's no shocker as the glasses get stronger. I will probably try to move in increments like you, every few months I will increase as long as I have accommodated appropriately by then. I am only in my second year of college and I am double majoring so I have 2 maybe 3 more years ahead of me.

Iain 16 Jan 2017, 07:25

Zach like you I have been intent on getting a myopic Rx.

I started slowly and have built up over my years at uni. I came to uni aged 17 in Sept 13 with glasses and cls -1.

Three times a year I increase the cls Rx by -1. Towards the end of my second year the glasses Rx was higher than cls.

I use gas permeable cls and wear them all day generally only taking them out once per week when I clean them and wear glasses. I am very careful not to experience any vision without either cls of glasses.

My 4 year course ends this year. Last Aug the cls increased to -10 and glasses -11.5, I got my first myodisc glasses. As a Maths student I devised a rigid plan to increase my Rx. Last week I changed to -11 cls and -13 myos. It costs me a lot and I have worked throughtout uni to support my ambition.

When I leave I want to be wearing -15 glasses for my graduation photo. I deliberately wear glasses when with friends and family and they know my Rx is increasing.

I don't know how high I can go. The past two increases have taken a while to get used to. With each change distance is ok I need to work on close up. Immediately after an increase I can read in bright light only and over the days/weeks I force myself to bring the work closer to my eyes. This present increase is still being worked on.

Is this a permanent change? I would love to know but dare not test it. I have worked so hard to get this far I am happy that I can see with myos.

Cactus Jack 16 Jan 2017, 05:46


Sounds like you need to slow down a little on the increases if you are noticing some blurr on your phone. Right now, you are using your Ciliary Muscles to compensate for the extra minus in your contacts. As an FYI, your -7.00 glasses have approximately the same optical effect as -6.50 contacts because of Vertex Distance effects in the glasses.

When you read with the -6 contacts at typical reading distances of about 14 inches or 36 cm, your Ciliary Muscles are having to add an additional +2.75. At typical smart phone distances, I would estimate as much as +3.50. In dim light, your pupils open and your range of useful focus decreases. It works like the f stop on a high end camera lens where the phenomenon is called "Depth of Field".

I would suggest staying with the -6 contacts or the -7 glasses until you don't have any problems reading text on your phone and then increasing in no more than -1 increments.

May I as a few questions?

1. Where do you live?

2. What are the subjects you like best in school?

3. When was your last eye exam?

You need to start thinking of the strategy for your next eye exam. At some point, you will need to get an eye exam to judge how effective your program has been. However, you should NOT go back to the ECP where you got your last exam. At your age, really significant increases in Myopia, typically don't happen naturally.


Zack 16 Jan 2017, 01:28

Hi, I would like to start inducing some myopia. Preferrably my prescription would reach -6 or -8 or more, but I would really enjoy any increase.

I am 19 years old and in school at the moment.

At the moment my prescription is at OD -2.25 and OS -2.5.

I wear contacts primarily but I do have a pair of glasses. I first conditioned myself by putting my -2 glasses over my -2 contacts, which I was able to get used to quite quickly. I then ordered contacts in -6. I have been wearing -6 contacts for the last week and everything is perfectly clear at this point with no issues other than slight blur on my phone when it is dark or dim. I have been wearing them all day everyday for the most part as they are extended wear ones, but I do usually take them out at night. I also have some OD -7 and OS -7.25 glasses that I have been wearing while my contacts are out at night before bed.

I am wondering what kind of steps I should be taking with my prescriptions in the future and how large (as in, what increments and how often). I have read up on the previous entries to this forum and it looks like taking too big of steps is detrimental to the process as the eyes cannot handle it, and I do not want to waste my time or money. Any other important information that you think I should know would be helpful too!

Cactus Jack 09 Jan 2017, 18:10


You need to go above -2.00 during the "training" process. Maybe as high as -4.00, but you have to work up to it.

The way to get prescription Contact Lenses when you don't really need them is to investigate some Contacts that change your eye color or "costume" contact lenses that are moderately popular around Halloween that make your eyes look really scary. You can say that you have been invited to a Costume Party.

What you are interested in, is the Diameter and Base Curve. You will need that information and the desired power to order contact lenses. The major benefit of getting professionally fitted Contact Lenses is that training on inserting and removing the contacts is included and also how to care for them. Good Hygiene is vital when working with Contact Lenses. Improper care can damage your Corneas.


Loveglasses 09 Jan 2017, 12:41

Dear Soundmanpt and Cactus Jack,

Thanks for your opinion. I think I will try it with contact lenses. Shall I start with -1.50, -2.00 or more? With the -1.50 glasses I can see really good. So maybe I can take a bit stronger. My goal is to do an eye exam and the result is about -2.00.


Cactus Jack 09 Jan 2017, 11:03


As Soundmanpt said, you may be to old to be able to induce any Axial or True Myopia. That involves causing your eyeballs to grow. It is very likely that your genes will not let that happen.

However there is another type of Myopia called Pseudo or False Myopia that may have some possibilities, but as Soundmanpt said, you have to either wear glasses or contact lenses every waking hour for that to be occur. Pseudo Myopia is considered "temporary", but temporary can be a long time under the right conditions. You could also do GOC (Glasses over Contacts) if you want to.

We can likely help you with any of those.

May I ask why you can only wear the -1.50 glasses about 10 hours per week? Maybe we can help you work on that also.


Soundmanpt 09 Jan 2017, 10:21


Your nearing or may already be at the point where "inducing myopia" might not be possible. But to have any chance at all one thing you will have to change from only wearing your -1.50 glasses 10 hours a week. That is not nearly enough to induce even a small amount of myopia. The only way is to go completely full time wearing your glasses. That honestly means from the minute you open your eyes each day you want to put your glasses on and keep them on until you are back in bed at the end of the day. Do this for about 2 months and then recheck your eyesight. All your doing now is wearing your glasses as "recreational use"

Loveglasses 09 Jan 2017, 07:53

Hello my name is Peter from Austria. I just recognized this site and saw that there is a possibility for my wish.

I would like to be short-sighted. I'm 25 years old.

I really love wearing glasses. Two years ago, I did an eye examination but the test said 0.00. But I still wanted to have glasses. So I ordered one in the internet with -1.50. I wear them when I am alone or drive the car. But this is not so often, maybe 10 hours per week. I can see perfectly with them. Today I did a new test and the result was nearly the same. 0.00 and - 0.25.

Do you think there is a possibility to get short-sighted (-2.00 would be great) and how can I do it?

Thanks for your opinion!

Soundmanpt 06 Jan 2017, 09:25


I also think starting off with -2.00 glasses might be a little bit too aggressive for your eyes. Even though your eyesight wearing your friends glasses was very clear only wearing them for a few minutes is much different than wearing them full time. So even if seeing distance was good wearing them seeing things close up might be uncomfortable for you. I was a bit confused as to if you were saying that you actually need -.50 correction for both eyes are if you even have glasses in that prescription. So if you actually need -.50

glasses then I would suggest ordering your glasses with -1.25 lenses. If you don't have glasses then I would suggest -1.00 as your first g;lasses. At the same time your ordering these glasses I would also order the same glasses in -2.00. By ordering the same glasses once your eyes are fully adjusted to the -1.00 or -1.25 glasses changing to the stronger ones no one will notice the difference except you. I'm sure you don't want anymore questions about your glasses than necessary. The most important thing in attempting to induce myopia is constantly wearing your glasses from the minute you open your eyes in the morning until you go back to bed that night. As for as being able to drive wearing your glasses, that shouldn't be any problem at all. Your eyes should adjust to your glasses (-1.00 or -1.25) very quickly. Actually it will likely be a bigger problem for you getting used to wearing glasses full time then it will be for your eyes to adjust to the prescription. So I would say at first if you need to drive somewhere first thing in the morning then you might want to take your glasses off. But by mid morning your eyes should be adjusted to your glasses and your vision should be perfect with your glasses on. I'm sure that you will know when your eyes are comfortable wearing glasses to drive. I'm guessing by the 3rd day your going to be very comfortable wearing glasses. Once your distance and close vision is completely clear wearing your glasses then you want to switch to the stronger glasses.

Cactus Jack 05 Jan 2017, 19:36


-2.00 may not be a good place for you to start. Have you had and eye exam recently? It is best to start developing a strategy with your actual prescription. If you decide to get an eye exam and the examiner says you need glasses, do not order them yet. Say that you would like to bring a friend to help you choose frames. Then let us know your prescription.

At 27 it is unlikely that you can induce any Axial or True Myopia. However, you may be able to induce some Pseudo or False Myopia. They have different causes, but have the same results, you need - glasses for correction.

May I ask your occupation and where you live (country). That can affect our suggestions.


Abbie 05 Jan 2017, 17:40

A lot of people in my family get reading glasses and then need to wear plus glasses all the time in the 50s.

I really like the look of shortsighted glasses lenses so don't want to end up long sighted.

I don't glasses think I'm with -0.50 both eyes. I've tried friends glasses on and could see very clear with them think were -2.00

I'm 27 so should I order some -2.00 glasses and wear all the time. I would prefer to be short sighted than long sighted.

Also would it be ok the use them for driving once I'm use to wearing them

Likelenses 30 Dec 2016, 20:22

Precisely, LL. You can "only" wish for her. You just revealed more than you realize. She's the ideal woman that you wish exists, so you made her up. In your mind, she exists. In your messages on eyescene, she exists.

You make up these stories about Cheryl and other women that are so very fond of you. They all want to date you. It's because that's what you wish was the truth.

Wishing for things that are not true. But through fiction, you try to make them come true.

Soundmanpt 26 Dec 2016, 09:53


After re-reading your first comment from "18 Dec 2016 19:09" I thought you were wanting to continue wearing your -5.50 glasses, but your eyes are finding it more difficult for seeing near. However the question you were really asking is about slowly returning to your actual prescription. I think you might not want to go back to wearing your -3.50 glasses because as your noticing your eyes are starting to change which is a very natural thing as you approach 40. By going to -3.50 now it's very possible that in the next year even your -3.50 glasses may feel too strong for your eyes and you would be needing even weaker glasses. If you want to retain an actual prescription of -3.50 you probably should continue over correcting your eyes with stronger glasses, just not -5.50 glasses much more. It seems that your eyes are quite comfortable with you husband's glasses which are -4.75 so get yourself some glasses in that prescription including your astigmatisms. If your -5.50 glasses are still comfortable for distance yu may want to keep them in your car to wear for driving.

You mentioned that you never started wearing glasses until you were dating your Bf / husband. Did he encourage you to start wearing glasses or was it just because he wore glasses that prompted you start wearing glasses?

Josh 25 Dec 2016, 17:33

Wantglasses, any news about your vision?

Late30sGirl 22 Dec 2016, 18:23


By no means I am an expert, but I do have some similar experience.

I started using glasses full-time with a very small prescription (less than -1 in myopia) when I was in my early 20s. By using full time and later using stronger lenses, my eyes became much more myopic (-3.5D).

My sense is that I probably needed a stronger prescription since the start, but doctors do tend to prefer to give lower prescriptions whenever they think it is possible.

If I were you, I would use it fulltime at first and start trying out some stronger glasses / contact lenses.

martian1 22 Dec 2016, 17:23

Hello everyone, my prescription is OS plano and OD-1.0 should i get glasses already? Can i still induce some myopia in my left eye? i am 24 years old. Thank you so much!

Soundmanpt 22 Dec 2016, 10:32


Actually the test you did with your husband's glasses is why I was suggesting that you might want to consider progressives. If your eyes have been fine wearing your -5.50 glasses for the past 5-7 years bit only recently you're beginning to have trouble with your near vision it's because your eyes are starting to change which is very common as everyone approaches their 40's. Until recently your eyes have always been able to read fairly comfortably even with your eyes being over corrected. But your eyes are starting to weaken for seeing close up and this is why your glasses aren't as comfortable as they always have been. Your test with your husband's glasses is really about the same as what I suggested. By wearing progressives and leaving your distance the same -5.50 and including an add of +1.00 that is the same as wearing -4.50 for reading. I assumed that you wanted to keep your distance vision the same since your eyes have been wearing that prescription for the past 5-7 years? That was why I asked if your still seeing distances perfectly with your -5.50 glasses?. Of course as long as you don't mind wearing slightly weaker glasses then you may want to order single vision glasses in the same -4.75 as your husband's glasses but with your astigmatism included. But you do understand that your eyes are changing and even with getting weaker glasses it is likely that reading small print is going to continue to get more difficult. This is why progressives might be better becasue that way as your eyes change you can still maintain the same -5.50 for distance but increase the add as needed.

Late30sGirl 21 Dec 2016, 20:39


Today I tested my DH glasses (-4.75, I believe that was the last prescription that I made him glasses) and worked great... (maybe my -5.5 was too much for my eyes) Not perfect science (his astigmatism prescription is different) but should give me some pointers...

Should I test with contact lenses? It is easier to test without having to buy new glasses and having to explain why I am buying new glasses again...

Likelenses 21 Dec 2016, 20:12


Your concern over the use of progressives at this point is valid.

Stay with the strongest minus that you can tolerate,to keep your cillary muscles in shape.

Late30sGirl 21 Dec 2016, 20:02


You are right regarding the first MD. He was probably old school. I did get my first pair of glasses few years later, but the doctor said to use only in classes or when I was driving. I became full time wearer only later, when I met my BF / DH and became less shy of using it (maybe a little bit too much).

I did the tests that you advised. I could read fine with my current prescription. My concern of using progressive lens now is to make my eyes worse. Wouldn't this make the muscles less "exercised"?

bracesfan 20 Dec 2016, 12:29


It´s greatly improbable that you would get crosseyed just wearing prisms. With prisms your eyes will only turn in or out but after taking them off your eyes will turn back. It´s true that with significant amount of prism you could see double, and even short time after taking glasses off, but no crosseyed. For seeing double is simpler to go for base in. Believe me, I wear big numbers of prism not needing them for quite a couple of years :-)

If your eyesight is now blurry all the time that is exactly what you're wanting. Because you're barely only 16 makes it much easier for your eyes to be changed then someone a little older than you. When you got your glasses how did your eyes feel wearing your -1.00 glasses for the first time? I have a feeling you weren't wearing them very long before they were completely comfortable and you were seeing everything perfect with them.When you switched to the -2.00 glasses i'm sure your eyes felt the difference. Did you have any problem adjusting to them? Your distance vision should be very good with your glasses but any problems with seeing things close up such as reading from a book? Have you placed your order for stronger glasses yet? Since you got your glasses and started wearing them full time has anyone siad anything about how often your wearing glasses now. I mean aren't you wearing glasses much more often now than when you were wearing your fake glasses? Just curious what glasses have you been ordering? Are they a good fit and how do you think they look on you?

wantglasses, you´re in an age where your eyes still end growing up, so if you do this, the optical nerves will adapt to a new position, then you will devolp more myopia some astigmatism and obviosly the strabism that you want, strong glasses will be ready for you.

Josh 19 Dec 2016, 19:24

if you wanna be cross-eyed what you have to do is force to keep your eyes cross, when both eyes are glue to the nose what you have to do is get only one eye straight, and keep them like this a pair of minutes, do it all the time you can and i garantee your eyes will be crossed in a few weeks

I have always loved the look of crossed eyes. When I was really young I had a friend who was cross eyed, and I thought it was so cool, loved the way her eyes looked, and her glasses looked even more amazing than all the other glasses I had ever seen, the lenses lokked amazing! They were so big on the outsides. It is hard to explain, but I have always wanted to be cross eyed.


My eyesight is now blurry all the time! It might be blurrier later in the day, but not by much.

Soundmanpt 19 Dec 2016, 09:54


I saw your reply to "noname" and you really seem thrilled that you're quickly becoming dependent on your glasses to see properly. Hard to believe that just a few weeks ago you could see that same menu board perfectly without glasses and now it's too blurry for you to read without your glasses. Now that your wearing glasses that you actually need to see with is it what you dreamed it would be like? It doesn't sound like you have any regrets at all about what you're doing to your eyes which is good. It's a lot different than wearing fake glasses isn't it? So of course after wearing your glasses all day when you take them off to go to sleep i'm sure things across your room are pretty blurry. But whn you wake up in the morning has your eyesight returned to normal and things are clear in your room or are they slightly blurry or about as blurry as when you took them off the night before?

You haven't really ever said why you want so badly to be cross eyed? That almost seems more important to you than even being nearsighted. You do understand that your crossed eyes would only be seen when you take off your glasses? With your glasses on your eyes won't appear crossed because your glasses will keep them lined up properly. So people will only see your crossed eyes when you take off your glasses. And you won't be able to go without your glasses because the double vision will very quickly cause you headaches not to mention you're nearsightedness.

Soundmanpt 19 Dec 2016, 09:03


I'm a bit sur[rised back when you were a teen and you had a prescription of -.50 with a -.50 astigmatism that the doctor didn't fit you with glasses. Granted it was a rather weak prescription but none the less you would have benefited from glasses. Maybe his thinking was that because you were a teen girl you likely wouldn't wear them anyway since wearing glasses wasn't very popular for a teen girl to be wearing at that time. But you were at the borderline of passing the vision test for driving. So in your early 20's you finally got your first glasses in your prescription and wore them full time. But after wearing your glasses a while you didn't feel like like your weak prescription was enough to justify your wearing glasses. You shouldn't have felt as if your eyesight wasn't bad enough for you to be wearing glasses just because you were still able to see pretty well without glasses. They still allowed you to see things more clearly and read signs in the distance. Only you knew how much your glasses helped you to see things. Once you found this site and started ordering glasses stronger than you needed until you were wearing -5.00 glasses without any problem and you actual prescription had increased to -3.50. But now thta your approaching the age of 40 wearing -5.00 glasses is getting more difficult for you. The over correction you continue to wear is now uncomfortable for your near vision. Is your eyesight still very good wearing your -5.00 glasses for seeing distances? You probably don't want to start wearing your actual prescription of -3.50 because you don't want your actual distance vision to slowly reduce. As a test you should try wearing the glasses you have with the =4.00 prescription to see if they are more comfortable for seeing close up.If they are then you may want to consider ordering a pair of progressives. Order them with the same -5.00 for distance but include +1.00 for the the reading add. You may want to do the same test with your -3.00 glasses to see if they are even better for reading. If so then you would want to make the add +1.50 or +2.00.

Josh 19 Dec 2016, 08:01

wantglasses if you wanna be crosseyed i could show you how to do it, you can find me in lenschat

Cactus Jack 18 Dec 2016, 21:45


I apologize, for not remembering your age and other personal information. It is very hard for me to keep track of all our members, so I really don't try very hard and just ask again.

I can understand the desire to Induce some Myopia, it is common or this thread would not exist. May I ask why you want to be cross eyed?

I suggest you think very hard about doing that. Glasses with a lot of prism are hard to make, expensive, and often have poor optical characteristics. Because of the prevalence of muscle surgery, making and fitting glasses with significant prism is almost a lost art. Mostly the glasses are made by specialty labs and the results are not always satisfactory or wearable. One of the reasons prism glasses can be expensive is that they have to be remade several times to get them right.

Also, when you are significantly cross-eyed, you only use the the inside area of the lens near your nose. Often the glasses are made using small round frames with no prescription in the outside area of the lens, something like myodisc lenses, That keeps the outer edge thickness and the ultimate thickness of the lens blank from being extremely heavy and thick.


WantGlasses 18 Dec 2016, 21:05

Cactus Jack

Everything is the same as my answer as November 9th, excpet I am now 16 years old. Ad I have said earlier I just really want to need glasses and be cross eyed! I would live to need glasses with big lenses.


Yes, I am so happy!! It feels amazing, like a dream come true, and it is. I could tell the pictures were there but they were fuzzy, and the words were non exisitant, until I squinted! I really cannit wait, I love that my eyesight has gotten worse, and I actually need glasses, and even more I love that I am getting new glasses even if the frame is the same. I just cannot wait to fail an eye exam, and have a doctor tell me I need glasses and that I am cross eyed.

Late30sGirl 18 Dec 2016, 19:09

Since I was a teen, I had very small myopia prescription (-0.5D or less and 0.5 for astigmatism). I was told by the doctor that correction was not needed.

When I met my husband (full time wearer, -4.25D) in my early 20s, I fell in love (with him) and with his minus glasses. This was what I needed to take the courage and become full-time wearer.

After a while, as I was not happy with my prescription (thought people would be joking about my almost lack of correction), I found this website and started using more correction. First -2, then -3, -4 and now around -5 for the last 5-7 years.

The inducing seems to be working, my real prescription grew quickly and after something like 5 years (when I was 30), prescription arrived at -3.5 and stayed there, with the same astigmatism as before.

In the last 2 years, it has been increasingly difficult to maintain the over-correction, specially for near vision... I am considering slowly converging to my true prescription.

What are your thoughts? I am almost 40 right now...

 18 Dec 2016, 17:14

wantglasses I remember you only got your glasses a short time ago. Are you happy that you can't see very well anymore without glasses? How does it feel to really need glasses now? How blurry was that menu board at the drive thru? wow, I guess you can't wait to get stronger glasses now?

Cactus Jack 18 Dec 2016, 13:32


Yes, very likely. It depends on many factors and there is no way to predict how long it will take. Because convergence is a natural occurrence when you look at something close, you could probably be wearing 10/10 BO or even 15/15 BO tomorrow, IF you could get the glasses. However, it is not uncommon for sudden changes in prism correction to cause nausea and dizziness until you get used to it.

It would be helpful if you would be more specific about your desires. and goals and how aggressive your situation allows you to be.

You need to be very used to your prescription and ideally have blurry double vision without your glasses so your need for an increase is obvious. Also, you need to know what to say in the interview, prior to the exam.

May I ask a few questions?

1. Your age and gender?

2. Your occupation?

3. Where you live? (Country and region)

If you would prefer to discuss this privately, you may contact me at


Wantglasses 18 Dec 2016, 11:52

Cactus Jack

Doing this would make me need BO glasses? How long do you think it will take before I get cross eyed? Also at what point should I go to an eye doctor to finally get prescribed glasses?

Cactus Jack 18 Dec 2016, 11:15


It is even easier than Inducing Myopia. Just order some glasses with 5 BO in each eye and reduce your PD by 3 mm. There are a few things to be aware of.

BO prism will cause your eyes to turn inward or converge. It is a natural function that occurs any time you look at something close. It probably won't take very long before you frequently have double vision without the prism correction.

When you read with your BO prism, your eyes will have to converge more that they do without BO prism.

Many online retailers will not do prism above 5 BO in each eye. (e.g. Zenni) I believe Optical4 Less will go up to 11, but I am not certain. Beyond that, you will need to find a local source with an official prescription and $$.

5 BO is not noticeable by others. Even 10 BO is not very obvious by looking at you. Increased edge thickness of about 1 mm per Prism Diopter is the most noticeable thing.

You may experience a reduction in VA with higher levels of prism. That may be related to a difference in the location of the Optical Center and your Central Axis of Vision. Prisms have NO Optical Center, but the underlying Sphere prescription does.

Most ECPs are very reluctant to prescribe first prism correction, unless the need is very obvious. However, once you are wearing them, it will not be difficult to get an increase if you start having double vision problems with the BO glasses.

As Soundmanpt said, once you start wearing prism, it is very hard to go back.


Wantglasses 18 Dec 2016, 07:27

I know to get the same frames. No one has noticed that I have started wearing real glasses. I am 110% sure I want to make myself cross eyed. I have wanted it for as long as I can remember.

Soundmanpt 18 Dec 2016, 03:27


It seems like your eyes have adjusted very well to wearing glasses and their having the effect you want on your eyesight. Now that the -2.00 glasses are completely comfortable to you then yes it's time to order stronger glasses again. Because as you know it will take up to maybe 2 weeks before you get your glasses once you pace your order.I would suggest getting the same glasses as you have now so no one will notice your glasses are different. Since you started wearing glasses with a prescription has anyone noticed or asked any questions about your glasses? I really think you need to think long and hard about it before you try to make yourself cross eyed. Becoming cross eyed is considerably different than just making yourself nearsighted. As you are beginning to tell being nearsighted just makes things blurry but your still able to see even without glasses. But being cross eyed will mean that not only will things be blurry but you will have double vision as well. There really is no fixing crossed eyes. Being nearsighted if you were to someday change your mind and wanted perfect eyesight you could get lasik.

Wantglasses 17 Dec 2016, 13:26

I think this has worked!! I can see perfectly through the -2.00 glasses now, and witgout glasses and even with the -1.00 glasses my vision has gotten blurry! I could not read what the drive-thru menu said last night without glasses! Should I order new -3.00 and -4.00 ones? Also, when can I start trying to become cross-eyed?

Hi Svensont,

I've decided to take up Cactus Jack's suggestions of ordering glasses with 5 BO prism. Am planning to do it in the New Year and report back here on my experiments

Cactus Jack 13 Dec 2016, 07:58


Yes, it was a bit off topic. I try to not do that, but I don't want anyone to misrepresent my background and think I am an ECP. Guess I am an "Amateur" in the original sense, as one who studies something out of "love or knowledge" about a subject.

I have been accused of being the type person who, if asked the time, will tell you how to build a watch. Sometimes, I offer very short answers to specific questions. Some years ago, I was approached by a very attractive young woman in an upscale department store, she asked, "Do you have the time?" I said, "Yes!". Unfortunately, she was asking because she didn't have a watch. She was confused b my answer, so I looked at my watch and said "It is 2:27". She smiled, thanked me and walked off - much to my disappointment.

I really like your Vertical and Horizontal terms. I guess I tend toward the "Horizontal" and have never even looked at the Twitter site, which could be where the "Verticals" hang out. The characters limit would leave me speechless.


svensont 13 Dec 2016, 07:37


And what have you decided to do? What prism will you order?

Cactus Jack,

>>Rote learning fundamentally teaches you to memorize a few solutions to a few common problems. Understanding teaches you how to analyze different kinds of problems. I you understand how something works, hopefully be able to solve almost any problem that comes along.

Slightly off topic, but how true that statement is. I too have done some technical teaching and despair of the rote approach. I came up with the term, Vertical Knowledge for the sort of education that many commercial training companies provide. Horizontal learning is the proper approach. I had someone tell me once, if you can;t tell me in a 125 character tweet I don't want to know.

Cactus Jack 12 Dec 2016, 21:41


I have often wished that I had studied Optometry or Ophthalmology instead of Electronic Engineering, but it is way too late now, I am 79.

I have said on many occasions that I am NOT an Eye Care Professional (ECP). I studied and learned about optics in Physics class and vision by studying and learning about vision. I wanted to analyze and solve my own vision problems when I could not get satisfactory answers from ECPs.

Over the years, I have done a lot of industrial teaching and have gained a reputation as being a pretty good "explainer". My goal is to foster UNDERSTANDING, rather than Rote learning. That is why my explanations tend to be long.

Rote learning fundamentally teaches you to memorize a few solutions to a few common problems. Understanding teaches you how to analyze different kinds of problems. I you understand how something works, hopefully be able to solve almost any problem that comes along.

Over the years I have learned a lot about my own vision problems and other peoples vision. I try to analyze their situation objectively and also teach about how vision works, if I can. We have some ECPs as regulars on ES and I frequently ask them to check my work and suggestions. I am not the least bit reluctant to suggest seeing an ECP if someone posts a question that is beyond my skill level.

I would like to help you do a bit of low cost experimenting if you are interested. If you were here in the US, I would suggest some low cost glasses with several different prescriptions from Zenni. I think you can order from Zenni Optical and have the glasses sent to Australia, but i don't know if there would be any customs duties involved. Could I ask you to check that out? No point in offering suggestions that can't be done at reasonable cost.

The first step is an accurate prescription for distance. Everything starts there. From you distance prescription, deriving the best prescription for nearer distances only involves a tape measure and some simple math.

I am tempted to suggest a dilated exam and the best time time of day as a starting place. Any thoughts?

BTW, If you would like to discuss any of this privately, please feel free to contact me at


stevesyd 12 Dec 2016, 14:00

Yes I think I do need to see someone else.

However I do have and wear glasses as a graphic designer as I'm always in front of a computer screen.

It's just I would like something for other distances. I do have a seperate prescription just to correct the astigmatism only. Like I said it was just the attitude I from the optometrist got suggesting it's not necessary. But I will try it regardless.

You seem to know an awful lot about this... Seems like you should be an optometrist!


Cactus Jack 11 Dec 2016, 17:06


It would seem to me that vision requirements of a graphic designer is just one notch short of that of an Olympic Sharpshooter. You probably need a new optometrist. The one you have probably does not understand what you do for a living.

The main problem with low Astigmatism is that it makes text awkwardly fuzzy. Astigmatism can cause your eyes to have two focus distances or powers. Depending on the Axis or your astigmatism and the direction of the strokes of the letters, some strokes will be clear and others will be fuzzy. If your eyes try to focus on the fuzzy strokes, they will clear up and the formerly clear stroke will be fuzzy. It is a no win situation, but your brain does not know it.

If you have your complete prescription, I would like to suggest a couple of things.

Order a pair of low cost glasses on line from Zenni Optical. I think you can do it from Australia. Here in the US. Zenni offers glasses for as low as US$6.95, but you have to look a bit for the $6.95 frames. The only extra you should consider is the $4.95 Anti-Reflective coating. Shipping is US5.00, here. I don't know what it to Australia. I recently ordered some glasses for a friend and the total was US$16.90. The only thing you probably don't know is your Pupillary Distance (PD). It is very easy to measure using a mm rule and a bathroom mirror.

The other thing I would like to suggest is to read the piece I wrote entitled "Hot to Study for an Eye Exam". I think you will find it helpful.

I have some other suggestions, but they can wait. Lets see how these work before spending significant money. If you have any questions about ordering glasses, let me know. They can also do prescription sunglasses for just a little more. If you order more than one pair of glasses there is only 1 shipping charge.

If you can order some low cost glasses from Zenni or other on line retailer, that will give you an opportunity to try some glasses for not much money. If you order glasses, you only need standard lenses with the lowest Index of Refraction (IR) they offer, about 1.50.

Please get over the idea that you need a certain strength glasses before you can officially wear them. You are the one with the job that requires good vision and you are the one that gets the headaches.

Some years ago, I noticed that people in some countries wanted "Official" approval to wear vision correction. The UK seemed to be the most prevalent one. As an April Fool joke, I came up with the idea of the Ministry of Vision to license vision correction devices for a fee. Similar to the Radio and TV licenses. Your license number would be displayed on the temples of your glasses to show everyone that you had official Ministry approval to wear glasses. The Ministry of Vision was to be in the same building as the Ministry of Magic.

Some people didn't connect the proposal with April 1st and thought it was a serious proposal.


stevesyd 11 Dec 2016, 14:24

Thank you Cactus Jack,

First your questions.

1. What is your occupation?

- I'm a graphic designer so spend all day looking at screens.

When I was 21 and given -glasses I used to spend all day looking in camera viewfinders. I assume that was the cause.

2. Where do you live? (country)

- Australia

3. Why do you think you need to have some minimal prescription, before you need "acceptable" vision correction?

- The optometrist dismissed the need for my level of astigmatism correction as it's small. His words "Olympic sharp shooters would get correction". So I don't want people looking at them thinking they are clear, physiologically I don't want to look like I'm faking it. What's annoying about that is in some situations distance vision isn't 100% clear. But people with worst sight get to have perfectly clear vision with glasses.

I do need new sunglasses... so I thought about getting the astigmatism correction in them. That way I can test out that prescription first. Can see how they go for driving.

And yes Presbyopia is starting. There is a delay in focusing these days. While I can read small print I do have to strain and I get headaches.


Cactus Jack 11 Dec 2016, 09:45


At 38, you have limited options. You are probably not very far from needing additional close focusing help.

Additional Plus for distance will only have the effect of being nearsighted and making things blurry, unless you have some unrevealed Latent Hyperopia, which I kind of doubt. You cannot Induce True Hyperopia (corrected by + glasses).

In the Myopia department, there are actually two kinds with different causes. Axial or True Myopia is caused by your eyeballs having grown too long for the total power of your eye's lens system. If is very unlikely that your genes will let that happen at 38. Axial Myopia is considered permanent because your eyeballs will not shrink after they have grown.

Pseudo or False Myopia is caused by your Ciliary Muscles and Crystalline Lenses having trouble fully relaxing for distance. It is actually the same thing as Latent Hyperopia, but on the other side of 0.00. That is probably what you had when you were 21. A lot of close work can cause Pseudo Myopia. Pseudo Myopia is considered to be temporary, but temporary is a relative term. Temporary, in this instance, can sometimes be quite a long time. However there is a catch to trying to Induce some Pseudo Myopia, Presbyopia will soon begin to limit what you can do in that department.

Presbyopia, at some point, gets almost everyone. It is caused by gradual stiffening of the protein that makes up your Crystalline Lenses. Your Ciliary Muscles and Crystalline Lenses are your Auto-Focus mechanism in your eyes. Presbyopia actually starts in Childhood, but typically does not become a nuisance until your late 30s or early 40s. Your genetic makeup and visual environment are important factors in determining when you will need some focusing help, but it probably won't be long before you need some help with either bifocals or progressives.

May I as a few questions?

1. What is your occupation?

2. Where do you live? (country)

3. Why do you think you need to have some minimal prescription, before you need "acceptable" vision correction?

Vision is the MOST personal of all the senses. There used to be a stigma attached to needing vision correction. There was, when I was growing up (79 now), but that is no longer true. Glasses with carefully selected frames are now fashion accessories, some with 0.00 prescriptions. No one has the right to control how well you see, except YOU. The important thing is visual comfort in all situations. Even the need for a "weak" prescription can have an amazing difference in comfort and fatigue levels. Fortunately, you can correct low Hyperopia using your Ciliary Muscles and Crystalline Lenses, but it takes energy and effort. You have NO WAY to correct Astigmatism, internally. Even very low Astigmatism needs correction because it can mess up your vision at ALL distances and there is nothing you can do about it, except wear glasses or sometimes Toric Contact Lenses.

Vanity issues are still pretty common, but you need to get over that. The absolute best way to get over that is to just start wearing your glasses full time. You may get some comments, but those will stop in a few days and the only moments you will get are if you are NOT wearing your glasses. Wearing glasses is no more significant than getting some new clothes, getting a different style haircut, or growing or shaving a beard.


stevesyd 11 Dec 2016, 06:05


For as long as I can remember I was fascinated by glasses. Wishing I needed them.

At about 21 I got my wish albeit not what I had hoped. Very mild short sightedness -.5 / .025 with an astigmatism of about the same from memory.

Fast forward to the age of 38. I am now far sighted plus I still have the small astigmatism. Still a fairly week prescription of +.5.

So I do need them for computer screens they also seem to help in artificial/low light situations at further distances. But obviously I see distance better without.

While I can get a small prescription for the astigmatism it's going to look so week and like fake glasses. So I guess I want to know is there anything I can do to make my sight worst? Without complicated GOC solutions as I think my wife would notice :)


Nathan 07 Dec 2016, 07:45

The Larissa story makes fascinating reading, especially how quickly her and her friend became dependent upon the prismatic lenses. Also, discovered similar stories in the archives from people like Daffy (who's attempting something similar to what I intend to do) and Jeremy. Cactus Jack: I work in marketing in the UK. I sit at a computer every day and have never experienced any double vision

Cactus Jack 07 Dec 2016, 07:15


There IS a risk of becoming NOTICEABLY "cross eyed" with BO prism or "wall eyed" with BI prism, IF you have a masked or hidden problem with anything associated with your Eye Position Control System. That is why I asked the questions about double vision, in my earlier post.

However, if the amount of prism is less than about 10 prism diopters in each eye, particularly with a Minus prescription, it is ONLY noticeable by YOU, when you are NOT wearing your glasses. The primary thing that is noticeable by others with BO or BI prism in your glasses, is a more significant difference between the outer or inside edges of your lenses. With BO prism the outer edges are thicker by about 1 mm per diopter. With BI prism, the inside edges are thicker, but the amount is less because the distance from the Optical Center (OC) of the lens is smaller than the distance to the outside edge.

The effects or wearing prism, go with the "territory". This is one of those "Be careful what you wish for" things.

Prism correction is a very complicated subject. I have had double vision issues for about 30 years, My eyes would like to turn inward, particularly when I am tired. It is called Fatigue Esophoria. The glasses I wear normally have 7 BO in each eye, but when I am tired, I need more prism to avoid double vision. Few people even notice the 7 BO, but people who know me well have asked about my glasses when I wear 15 BO. The outer edges are noticeably thicker, but I think they notice that the frames are different more than the edge thickness.


Soundmanpt 06 Dec 2016, 14:15


I remember reading the story about Larissa and her friend. As I recall Larissa started off only wearing very weak glasses for distance but was soon wearing her glasses full time and then she was prescribed with prisms as well. At one point her friend came over to watch a movie and Larissa had left her previous glasses laying on a table in front of them. Her friend saw the glasses and proceeded to put them on. After a bit of on and off with them she finally left them on for the rest of the evening. She went and had her eyes examined but she was told that her eyesight was perfect and she didn't need glasses. But even so she still continued to wear Larissa's old glasses quite often. At some point her and Larissa went on vacation for a week and during the drive to where they were going to be vacationing she had forgotten her sunglasses and found a pair of Larissa's glasses that had prism correction. Larissa warned her that by wearing them she might ruin her eyesight. For a short time she wasn't sure if she wanted to just continue to wear Larissa's weaker glasses without prisms or if she wanted to wear the stronger ones with prisms. She finally decided to wear the glasses with prisms the remained of the week. It wasn't long before her eyes were ruined by the glasses. She went for an eye exam and this time she was prescribed glasses with prisms. Great story!

svensont 06 Dec 2016, 13:26


Read posts starting from "Larissa 28 Jul 2002, 21:57" in Acuity and Prescription II thread, there is a story how her friend became defendant on base in glasses, also read Daffy posts, who also ordered some base in and got permanently used to them.

Cactus Jack 06 Dec 2016, 08:55


The Eye Position Control System (EPCS) is, to some extent, programmable. Prism can correct eye misalignment (Strabismus) or cause it. In some ways it is easier than Inducing Myopia. BO prism corrects or causes a small amount of convergence, (eye "crossing") which is a common event, every time you look at something close. BI prism corrects or causes divergence ("wall" eyes) which is NEVER required in a normal visual environment. Ideally your eyes should point straight ahead (parallel) when you look at distant objects. That makes BI prism more difficult to deal with, unless your eyes have tendency to turn outward.

It is possible to become dependent on prism correction. That is why many Eye Care Professionals (ECPs) are very reluctant to prescribe prism, unless the need is pretty obvious or the patient is already wearing prism correction.

May I ask your occupation and where you live?

Also, have you ever experience double vision?

If so, what was the circumstance?


Nathan 06 Dec 2016, 02:09

Thanks Cactus Jack. If BO will cause my eyes to go inward or converge, does that mean I'll go cross-eyed??? (would like to avoid this if possible). I'm 28 by the way.

Cactus Jack 05 Dec 2016, 15:34


I would suggest BO prism because it will cause your eyes to turn inward or converge. Convergence naturally occurs whenever you focus on something close. I would suggest considering 5 BO in each eye because that is the maximum Zenni will do. You should reduce your PD by 3 mm because of the convergence. 5 BO will cause each eye to turn inward about 3 degrees. It will not be noticeable by others, but it will increase the outer edge of your glasses lenses by about 4-5 mm.

Please let us know what you decide to do.

May I ask your age?


Nathan 05 Dec 2016, 06:49

My current prescription is -2.50 in both eyes (no astigmatism) but if I was going to order a pair of prism lenses online, what prescription should I start off with? Should I go for BI or BO? And what numbers should I fill in? Am doing this because I want to be truly dependent upon glasses rather than contact lenses (which I find myself reverting to most days)

Cactus Jack 03 Dec 2016, 15:57

please help,

The idea that you have to need a certain prescription before it is OK to wear glasses, is pure, unadulterated BS.

Here is a little Optical Physics lesson about what your Sphere correction (first number) means. The most important formula in Optics was discovered and codified by Sir Isaac Newton, of gravity fame, around 1700. It is:

Focal Distance = 1 meter (100 cm, 1000 mm, or 39.37 inches / Lens power in Diopters or its rearrangement: Lens Power = 1 meter / Focal distance.

To add a little about how Vision and its Correction works, we need to add this. The amount of Vision Correction you need is the opposite (sign) of your refractive error adjusted for Vertex Distance (VD). If your prescription i less than +/- 4.00, you don't need to concern yourself with VD effects.

If you need -1.00 Sphere correction, that means that your refractive error is +1.00. Now lets explore what that means. Using the formula above, that means that everything beyond 1 meter (a bit over 3 feet)is increasingly blurry. What that means is that you cannot read what is written on the board in school, read a menu board, recognize a face across a street, or legally drive a car.

Even a prescription of -0.50 means blurry vision beyond 2 meters or almost 7 feet. Everything listed above pretty much applies at -0.50. When you add in little Astigmatism (-0.25) the distances are even less.

NO ONE has the right to dictate how well you see or pass judgement on how you want to correct your vision or how much vision correction you prefer. It is YOUR choice, not much different than preferring a particular flavor of Ice Cream. If someone wonders how well you see without glasses, suggest that they get a pair of +1.25 readers at a local store and wear them full time. Up to a point, being Myopic is like having built in reading glasses.

I strongly suggest that you start taking control of your life when you wake up in the morning. Put on your glasses and start wearing them full time, with or without contacts. If anyone asks, just say that your contacts have been bothering you. You haven't mentioned where in America you live, but Winter with low humidities is upon us and low humidity is a common source of contact lens issues. If it is not exactly the truth, you are the only one that needs to know that.

Almost everyone is worried about what others will think or say when they start glasses. The comments or wanting to try them lasts about 2 days. After that, about the only time anyone will comment is if you get a new frame style. That comment will be at about the same level as if you changed your hair style.

I believe you said that you were in your Freshman year of Engineering. Engineers are people who make things happen. You need to get in the habit of making things happen, rather than hoping for something to happen. Why not start here and now. Don't feel guilty about wanting to wear stronger glasses, many people do because they enjoy the extra crisp vision.

If your serious about wanting to wear stronger glasses then you have to take the first step in getting their. Even better you have everything you need to get started. You just need to get your nerve up and start by wearing your glasses along with your contacts. By doing that it's the exact same thing as you buying -2.00 -.25 / -2.00 -.25 glasses.

Trust me that no one can tell by just looking at your glasses how strong they are. Just for fun try going to the mall and start looking at people wearing glasses. Unless they are wearing really strong glasses I am sure you won't have any idea how strong their glasses are. When you're looking at someone wearing -2.00 or -2.50 or -1.00 glasses they are all going to look about the same to you and anyone else.

please help 03 Dec 2016, 10:33


Yes I have both. I wear contacts all the time out of the house. I don't wear glasses much except when I am alone at home. I appreciate your help. I am a bit worried to just go in public with my glasses cause they aren't that thick and I will think people don't think I really need them, thats why I want them stronger. But I guess most people won't be able to tell by looking. Thanks. Soundmanpt, what you said makes sense I am just worrying I think.

Inducing Myopia always starts with Pseudo (False) Myopia. If you are lucky and your genes will allow it, it can turn into Axial (True) Myopia.

Axial Myopia is caused by a mismatch between the total Optical Power of your eye's lens system and the distance from your Crystalline Lens to the Retina. The distance is related to the length of your eyeball. Axial Myopia is considered Permanent, because the eyeball typically DOES NOT shrink after it has grown.

Pseudo Myopia is caused by the Ciliary Muscles and Crystalline Lenses not fully relaxing after focusing close or compensating for Minus overcorrection. Pseudo Myopia is considered Non-Permanent or Temporary. However, in this case, temporary can mean a very long time. How long depends on your age, how long you have worn the overcorrection, and the magnitude of the overcorrection.

You can have both Axial and Pseudo Myopia at the same time and their effects are additive.

A few questions:

1. Do you have both glasses AND contacts?

2. When do you wear glasses?

3. When of you wear contacts?

We understand what you want to do and we have helped many people achieve your objective. For this to work, you have to level with us. We understand that because you are still living at home, you have to be very careful how you go about this. We also understand that there can be Vanity issues. We can help you with methods that have worked for others.

It takes a little courage to pull this off, but you can do it, if you really want to. Effectively all you will be doing is speeding up a natural process, before your genes make it very difficult or impossible.

If you would prefer, we can discuss this privately using

The answer to your question about being able to induce real myopia or false myopia depends a lot on you. You're 19 so you could be approaching the age where your eyes soon start to become stable. That generally happens in your early to mid twenties. But if you have been reading past comments in this thread you will see the importance of having your eyes constantly exposed to a stronger prescription then you actually need. You already have what you need to get started. You have contacts and you have glasses. Wearing both of them together would be the same as wearing -2.00 glasses which is about where you want to start. But you seem reluctant about wearing your glasses outside of your house for some reason. Isn't the whole idea of inducing myopia so you will need to wear stronger glasses? Just because your glasses are only -1.00 doesn't mean they are too weak to be worn full time. Also only you and maybe your parents know what the prescription of your glasses are. The average person has no idea how strong your glasses are or how much you need them. I think you still stand a very good chance to induce more myopia than you have now, but even if you for some reason don't you should still be able to wear glasses at least as strong as -2.00 without any problem. I would assume being able to wear stronger glasses is what your mainly wanting anyway?

help please 01 Dec 2016, 09:45

Thanks for the help.

Cactus Jack,

Will i be able to get any real myopia or only false?

My last eye exam was in early October. My next eye exam is scheduled for about in a year or two. Probably two if I don't notice any problems, but I'm hoping to have to go back for new prescription next year. I wish I could get my hands on some -2 contacts but not sure how to do that. Thanks for your help.

What prescription do you think I would be able to reach?

Soundmanpt 30 Nov 2016, 06:46


Glad to hear that your glasses have arrived. Now that you have your glasses you need to start wearing them on a consistent basis. How well are you able to see with the -1.00 glasses? You're young enough that your eyes shouldn't have any problem with adjusting to your glasses. How does it feel to be wearing real glasses instead of the fake ones? I don't know how much you wore your fake glasses but now that you're going to be wearing glasses full time people may start asking you why you're now wearing glasses all the time? You will just need to convince them that you really like you look wearing your new glasses and that you have gotten so many complements on how nice you look wearing glasses that you really like wearing them. Just be careful if any of your friends want to try your glasses on because i'm sure they will notice that your glasses have prescription lenses in them. As your eyes start adjusting to your glasses you will start to notice that when you take them off at the end of the day or just to clean them things at a distance will be be blurry for a few seconds before going back to normal vision. The more you wear your glasses the longer it will take for your eyes to go back to your normal vision until your eyes don't go back to your normal vision anymore.

If your glasses for any reason aren't comfortable or don't fit quite right you can stop at any optical store including Wal-Mart and have them adjust your glasses for you. They don't charge anything for that and they won't ask an questions either. Now that your going to be wearing your glasses all the time you want them to feel comfortable.

Cactus Jack 29 Nov 2016, 20:19

help please,

Engineering is one of the fields of study that really encourage the development of Myopia. The amount of close work you need to do provides plenty of accommodative stress and you can certainly encourage it if you wish.

However, the fact that you have only developed -1.00 of myopia in approximately 13 years of school does not bode well for significant increases in Axial or True Myopia, which has a very strong genetic component. That does not mean that you can't develop some Pseudo or False Myopia.

The two different types of Myopia have different causes, but the results are the same, you need to wear Minus lenses for good distance vision. The key to Inducing Pseudo Myopia is wearing as much over correction as you can tolerate for as long as possible every day. At 19, you should have plenty of Accommodation Range and plenty of close work to help out.

As Soundmanpt said, all you need to do is start wearing both your contacts and glasses. Few people would notice that you are also wearing contacts under your glasses. You may need to do a little explaining as he suggested, but that will quickly become old news to everyone. Once you start wearing glasses (in addition to the contacts) you can increase the power of either the contacts or glasses with out much comment, provided you keep the same frame. That may require a little planning.

It is much easier to get glasses in almost any prescription, very inexpensively, online. All you need is your prescription, your Pupillary Distance (PD), and a credit card. Many of us have used Zenni Optical. The offer very good quality glasses for a little as US$6.95 plus shipping. The cost of the frame determines the cost of single vision glasses with standard lenses. Shipping is only US$4.95, no matter how many pair of glasses on the same order. There are only a few frames that are $6.95, but they are there, you just have to look around a bit.

It normal for you to be apprehensive about ordering online, but I think that you will be surprised at how easy it is to accomplish your objective. We have been able to help many people Induce Myopia. In doing so, we have learned what works pretty well and what does not.

You asked about how long it will take for your prescription to increase to -2.00. Think you will be very surprised at how soon that can happen. One of the important principles is that you have to wear stronger glasses than your goal. You have the means to be wearing -2.00 by using your glasses and contacts together, right now.

I have a couple of more questions for now.

1. When was your last eye exam?

2. When is the next one planned?

3. What branch of Engineering interests you the most?

Lets get started.

I would like to suggest a small change to the plan for the next few days. I think this will help overcome your apprehension.

1. Start wearing only your glasses for the few days. The suggestion of saying that your contacts are bothering you is a good one. Once everyone has become used to seeing you wearing glasses and you get comfortable wearing them full time.

2. Start wearing your contacts with your glasses.

3. You need to start thinking now, about 3 things.

A. Check out Zenni's offerings and try to find an inexpensive frame that is similar to your present frame.

B. Figure out where you need to have the glasses shipped. Three possibilities are a friends home, a Post Office box, or a private Mail Box.

C. Decide how you are going to pay for the glasses. You need a Credit Card, but you may not want the charge showing up on any credit card bill that your parents may see. There is such a thing as a Prepaid Credit Card. Many banks and reputable stores offer them. Do not confuse Gift Card and Debit Cards with Credit Cards. PayPal may be another possible option. I don't know if Zenni has a PayPal option.

I have given you plenty to digest. Please let me know if any of this seems reasonable. I am sure you have some more questions. If you feel uncomfortable discussing anything publicly, you may contact me at

Once you get started increasing your myopia you will wonder why you were so concerned. BTW, the highest anyone has gone with Inducing Myopia started in his late 20s and got to the point where he was reading and studying with -20.00 glasses. He started with about -4.00 of Axial Myopia and it took about 2 years. He was highly motivated. He badly needed to flunk an eye exam and he did. Most of it was Pseudo Myopia, which is not considered "Permanent", but it lasted long enough to accomplish his purpose.

I got my glasses!!

Soundmanpt 29 Nov 2016, 17:24

help please

Since your full prescription does have a slight astigmatism in both eyes i'm certain that your doctor only included the astigmatisms in your glasses and not in your contacts since it is so minor. So you shouldn't have any problem wearing both your contacts and glasses at the same time. I would suggest that tomorrow morning when you get up you should put on your contacts and your glasses as soon as possible. If you don't normally wear your glasses very often you may need to convince your parent's that that your contacts have been bothering your eyes and that is why your wearing glasses now. If you drive a car you may need to take off your glasses at first until your eyes get fully adjusted to your contacts and glasses together. Once your at school continue to wear both your contacts and glasses full time.

and my contacts are both -1.

im in school studying engineering.

i live in america. i would be scared to order online tho because i mostly wear my contacts out of the house, not glasses.

thanks for the help you guys.

how long do you think it will be until i need a stronger prescription? could i get to needing -2 by next year?

Cactus Jack 28 Nov 2016, 22:27

help please,

You should be able to induce some additional Myopia by wearing both your contacts and glasses. If your prescription is Sphere -1.00 in both eyes without any other prescription elements (e.g. Cylinder and Axis) and you have Sphere only -1.00 contacts, you should be able to wear both pretty easily at your age. That would be like wearing -2.00 glasses as Likeliness said.

If the above is correct (I need to know if it is not) there is little need to delay wearing both, provided you are used to wearing contacts. The important thing is to were the combination as much as possible, particularly when reading or using a computer or tablet. If you have trouble reading text on a Smartphone, just lift your glasses.

It would be helpful to know more about you.

1. What is your complete prescription?

2. Are you in school?

3. If so, what are you studying?

4. If not, what is your Occupation?

5. Where do you live? (country)

Even though you are living with your parents, there are ways to order inexpensive glasses online, provided you are a bit creative. Moe about that later.


Likelenses 28 Nov 2016, 20:56

The best thing to do is wear your glasses from the time you get up ,until you go to bed, with no cheating.

Do as much close work,and reading as possible every day,and when you do,hold the reading material as close as you possibly can,and of course be wearing the glasses.Sit as close to the TV,when watching it.

It is also helpful to get in the habit of squinting,especially when looking at things in the distance.

After doing this for about three weeks, then try wearing your glasses over your contacts,and if it is relatively comfortable, repeat the above while wearing both.

After several weeks of doing that you may find that you need stronger glasses,and should then book an exam.

Hi I have some questions.

Cactus Jack, I have seen you post before maybe you can help me.

I am almost 19 years old. I got my first glasses prescription just over a year ago with a prescription of -0.5 right eye and -0.75 left eye. I got an eye exam a few weeks ago (maybe a month or 2) and my new prescription is -1 in both eyes. I am wondering if my eyes will ever get to -2 or -3? I don't want them to be a bit worse.

Will they get there on their own? How long will it take?

How can I speed this up? I can't order any other glasses online cause I still live with my parents. Is there anything else I can do? Like where my glasses and contacts at the same time when I study or what?

Will they be able to get to -2 in a year or two? Thanks.

Soundmanpt 28 Nov 2016, 14:10


Just curious if your glasses have arrived yet or not? If not they should be coming any day now. Be sure to watch your e-mail because they usually always send a notice informing you that your glasses have been shipping to you.

Cactus Jack 14 Nov 2016, 07:52


Typical delivery is 10 days to 2 weeks. The lab is not in the US. They air freight the orders in bulk to California, I think, and mail them from there. Please let us know when they arrive and you can start wearing them.


WantGlasses 14 Nov 2016, 06:20

I just ordered my glasses. I hot the -1.00 and -2.00 only for now.

Cactus Jack 11 Nov 2016, 23:38


Yes, you have enough information to order now..

If there is a budget issue, you can just start with the -1.00.

I looked under Kids, Teens and there are only a few frames for $6.95. The style number I found was 126255. They obviously would like to sell the more expensive frames, but right now frame style is not very important. The first step is to select the frame. After that, you will ever the prescription you want to order. Read the order carefully and take your time for this first one.

Please ask if you have any questions. They will recommend some options, but you only need the free lens material with 1.50 index. They will recommend the AR coating, but you can specify None at the bottom of the list.

If you get confused you can save your prescription and designate the frame as a favorite. That way you can come back to your order more easily.

Please let us know what you decide to order.


WantGlasses 11 Nov 2016, 22:35


I can trust my friends' sister and my firends (not girlfriend, don't know where you got that from). I havd not told anyone, doesn't seem like the thing you tell people. In fact, my friends do not even know, I only told their sister. Yes, I got where Cactus is coming from with the same frame idea. Right now I cannot afford the coating, so I will skip out on that. You guys say it is optional anyways. Can I order now?

Soundmanpt 10 Nov 2016, 15:31


The advice that Cactus Jack has been providing you is the proper way to go about inducing myopia. You're certainly young enough that wearing the glasses suggested by Cactus Jack should work very well for you and give you the results that you're hoping for.

I do have a tip that should help when you're looking for the glasses you intend to wear. Looking at glasses on line is nice but it can be difficult to know what size glasses fits your face best. If you have some fake glasses that fit you perfectly or if one of your girlfriends have glasses that fit you well then you want to measure them across the front from the far outside left to the far outside right using that same millimeter ruler you used to measure your PD. If you have an average size face then I would think you will find that glasses that are around 128mm - 131mm should be a good fit for you. So when looking at glasses and you find ones you like check the "overall width" and try and stay close to what fits you best. If you are looking at Zenni they have around 800 glasses for under $13.00. If you add the AR coating which I also recommend so you don't glare and reflections from your lenses then your glasses will only be $18.00. If you get the 3 that Cactus jack is suggesting you get with shipping that would add up to $59.00.

Do you understand why Cactus Jack is suggesting that you get the same glasses but with the 3 different prescriptions? Once you get started wearing your -1.00 glasses and then you go to the -2.00 glasses by staying with the exact same frame no one will notice that you're really wearing different glasses except you.

The most important thing is that when you get your glasses that you wear them everyday from the minute you open your eyes until you're ready to close your eyes that night.

The idea of having your glasses sent to your girlfriends house is a good idea but can you trust her not to tell anyone what you're doing? You do know that you don't want people to know what your doing.

Cactus Jack 10 Nov 2016, 14:40


The answer to your question is Yes. But first, you need to order some glasses. If your budget allows, I would suggest ordering two or even three pair of glasses one with -1.00, one with -2.00, and one with -3.00 using the same frame, form Zenni.

I would suggest a low cost frame and standard single vision lenses and the low cost Anti-Reflective (AR) coating. The AR coating is not mandatory at this time. If you order more than one pair at a time there is only one shipping charge.

If you are unsure about the ordering procedure, let me know.

If you have questions you would prefer to discuss privately, you can contact me at


WantGlasses 10 Nov 2016, 10:31

I got 60 for the pd. I can get my glasses shipped to my friends' sister's place. I wear fake glasses a lot, almost all the time at home. My parents would not notice the difference. They do not wear glasses and know nothing about glasses. I have taken math and science every year, we have to. This year (8th grade) I am in physical science and algebra II. I have a question too. Will I eventually be able make myself cross eyed?

Cactus Jack 09 Nov 2016, 22:58


Quite sure. All you need is a credit card (it can even be a valid prepaid card) but first things first. I suggest you go to and look around. They offer amazingly high quality glasses for as little as $6.95. The frame determine the cost of the glasses. For now you really don't need a designer frame but you need a frame you like, because you will need to order several pairs of glasses with increasing prescriptions and as long as you use the same frame, few people will notice that you are increasing your prescription.

You will need to measure your Pupillary Distance (PD). It is extremely easy to do. There is information on the Zenni site about how to measure PD, but here is what I think is an easier way. You will need a ruler marked in mm and a bathroom mirror.

1. Hold the rule with 0 at the center of your nose.

2. Look at the scale and read the distance in mm from the center of your nose to the center of one of your pupils. Note the distance.

3. Measure the distance from the center of the other pupil to the center of your nose. Add the two together.

4 Repeat steps 1-3, three times and average the distances.

5 Tell me what it is.

Depending on your head size it will probably be between 56 and 64 mm between your two pupils. Do not try to measure the distance from one pupil to the other directly, it will probably not be as accurate as doing each eye independently.

The PD tell the glasses maker where to place the optical center of the lenses in your glasses, so it is important.

With the PD, you actually have enough information to order glasses with the following prescription:

OD (Right Eye) Sphere -1.00

OS (Left Eye) Sphere -1.00

Enter your PD

But don't do it yet. There are several things to consider.

1. Where will you have the glasses shipped?

2. How will you explain the glasses to your parents? (That is much harder than explaining them to your friends)

You might want to consider the very inexpensive Anti-Reflective coating (About $5.00) and shipping will be about $5.00.

What ever you do, you MUST have a plan. Inducing Myopia is not a fast process. It will take a few months before you are ready for an "official" exam and an "official" prescription.

Once you are comfortable with the -1.00 glasses to the point where you don't even notice that you are wearing them, you will be ready to increase the prescription to -2.00. When you are comfortable with -2.00, you increase it to -3.00. After you become comfortable with them, you will be ready for an official eye exam, but let us tell you the type of symptoms you report and where you get the exam.

Please do not try to jump ahead or try to be creative. We have helped many people fulfill their wishes and you need to follow instructions. Failure to follow instructions can lead to a slow down in developing myopia.

I strongly suggest that you do not do anything with prism until you have more experience and understand the nuances involved. It is much more complex than just a simple prescription for Myopia.

May I ask if you have taken any science or math courses in school?

It takes 10 days to 2 weeks to get glasses from Zenni.

While it might be tempting, It would be best to NOT try to borrow someone elses glasses UNLESS you know the actual prescription. At this time, I am operating on the assumption that you do not have any Astigmatism. Glasses to correct Astigmatism have a Cylinder and Axis component. If you do not need Astigmatism, unneeded Cylinder and Axis will make the glasses very uncomfortable to wear and will likely cause headaches when you try to read with them. Reading and studying with your glasses is very important in developing myopia.

I am currently 15 years old, but just a bout to turn 16 in a couple of weeks.

I live in America.

I am a high school student.

Where would I order glasses? Are you sure I can do it without actually needing them?


I am aware that being cross eyed would probably result in me having double vision, and it is fine by me. I used to have friend that was short sighted, cross eyed and had double vision, but with her (fat) glasses she was able to see one single just fine. I just love the cross eyes look and the glasses they wear look so amazing.

Soundmanpt 09 Nov 2016, 17:20


I suggest that if you are serious about wanting to war minus glasses that you look back in this thread and you should find more than enough information as to how to get prescription glasses and how to get started. there are plenty of comments from many others in here including Cactus Jack, Likelenses and myself. The idea of attempting to make yourself cross eyed is really a very bad idea. If you become cross eyed almost certainly your you would cause double vision. You should only work on the possibility of making yourself short sighted. Remember no matter what your age is you should at the very least be able to wear prescription glasses with -1.00 lenses even if you aren't able to induce any real myopia.

Cactus Jack 09 Nov 2016, 17:06


You are not the first and won't be the last.

We can help, but we need a bit more information.

1. What is your age?

2. Where do you live? (country)

3. What is your occupation? If a student, what is your education level?

If you do not presently wear glasses, you can easily order glasses, on line, without a prescription. The fat kind of lenses are probably PLUS lenses, but those probably won't work. They are used for correcting existing long sightedness and all they will do is make your distance vision blurry. Depending on several factors, you can probably wear MINUS glasses, but you need to start with a low prescription and work up as you get used to wearing them.

I love the way people's eyes look so small in them, and how you can see rings forming on the outsides if the glasses. I have wanted glasses for as long as I can remember. I have always been attracted to them. I remembe always getting so jealous everytime someone in my class got glasses,and getting mad everytime I passed an eye exam and had hear the doctor say, good news your eyes are healthy and you have excelent vision. I have a few fake glasses, but tgat is nit the same. I want real glasses. I want to need them from the second I wake up to the moment I fall asleep everyday. I just REALLY want glasses. I want to struggle seeing, especially that stinking chart. I want to hear a doctir tell me I need glasses. I want people to ask ME if they cantry my glasses on. I want to have to squint. I want to be able to see through my friend's glasses. I want them to say, dang you are blind to me when they try my glasses on. I also really wantvto be cross eyed. It is so unique and cross eyed people tend to have fatter glasses. I want fat glasses. Incase you can't tell I WANT GLASSES. Please help!!

@James: fair points. Myopia has been studied at great lengths, both the genetics and the environmental triggers. Like most aspects of human health and physiology, it's probably a combination of both.

Extreme myopia is connected to several genetic conditions, like Stickler's Syndrome and trisomy 21, often through effects on collagen, but this is probably not related to garden variety myopia that occurs in the bulk of the population.

I'm sure environmental factors play a role, but perhaps only for people already predisposed to myopia. I remember one classmate in college, who was Asian and a -10 myope, said on several occasions that she had been studying so long that her eyes were permanently focused close up. I also recall that her prescription increased several times in college.

I spent more time doing close work than 99% or the population, but I've been a lifelong hyperope. Of course, maybe my hyperopia would have been worse had I not studied so much, who knows?

That said, the claim that older adolescents and adults can become myopic, or significantly increase myopia, by wearing too strong minus glasses, seeing flashes of light, etc., lacks much evidence to support it, especially in people with no predisposition.

James 28 Sep 2016, 07:26

There is plenty of scholarly work on the environmental factors that trigger or induce myopia in humans. Of course, it is framed as a what NOT to do. As with animal studies, these things also relate to growing subjects, so probably none would have any effect on an adult wishing to induce myopia.

Just off the top of my head, I can recall the following:

- using a "night light" i.e. kids not sleeping in absolute darkness;

- insufficient outdoor time for kids, possibly having something to do with not using the developing eyes enough to look into the distance enough;

- linked with the above, doing lots of close work (think hyper-competitive Asian education systems and the explosion of myopia in the last decades in the most educationally competitive countries); and

- blocking off the peripheral vision of developing eyes.

Of course I have stated these very simplistically, and the mechanism by which environmental factors interact with genetic predisposition is still - in 2016 - not understood at all.

Will, there are a couple of things to keep in mind about that article. First, they studied Guinea pigs and not humans. Second, the animal models were developing and growing. Third, and related to the previous point, they were exposed to the cycling lights for a significant part of their youth. Thus, extrapolating this to fully grown humans is meaningless and impractical.

To my knowledge there have been no good scientific studies on inducing myopia in humans, for the obvious reasons. The only studies I know of looked at reducing myopia progression, usually by under-prescribing or wearing bifocals. These studies have not shown anything dramatic, just modest to no change in the progression as compared to control groups. Even a consistent finding that bifocals reduced the progression of myopia would probably convince most ECPs to prescribe them for their pediatric population, especially those with a family history if high myopia.

As much as many of us would like to induce more myopia, there's no evidence that wearing a stronger prescription than needed, or holding books closer to the eyes, will do very much, especially in people who don't have any predisposition to become myopic. I think the only real option is refractive surgery.

I recall some time ago someone posted an article on this thread about a rotating disc that as I recall had red,and white swirls on it.There was a warning that watching it for even short periods of time would create myopia.

There was no way to make the disc rotate,even though the article said there was.

Cactus Jack 25 Sep 2016, 16:20


I have not heard of that experiment before. There was another experiment, many years ago where they fitted baby chickens with minus glasses and they grew up with myopia. I think the significant factor with the Guinea Pigs was their age.

Flashing lights can induce what is called "Flicker Vertigo" in humans. You occasionally find flickering strobe lights in some entertainment venue that make you feel dizzy and occasionally induce nausea. I don't think most people could tolerate the flickering lights long enough to make any difference in their vision, even if it did.

Hey everyone,

have you read this article?

Do you think, it is possible to make this procedure on ourselves?

Since I'm not an english native Speaker, i do not exactly know how the experiment works.

Sorry, if it has been discussed already.

Cactus Jack 23 Sep 2016, 05:07


Please check Skype.


Taha 20 Sep 2016, 06:57

Cactus jack,

Sure i will buy a new pair with this prescription as soo as i return to cairo in 2 days ... And thank you 😊 yes, i studied english when i was little and i used to teach english conversation online for a while as well.

Cactus Jack 19 Sep 2016, 14:24


That is excellent. I just wanted to be absolutely sure so I could offer accurate suggestions. I suspect that if you wear your new prescription full time for the two weeks, you will not notice that you are even wearing them.

I would like to suggest that it is time to start thinking of your next increase and how you are going to order the glasses. I would suggest the following prescription:

R Sphere -5.25, Cyl -1.00, Axis 177

L Sphere -5.00, Cyl -1.00, Axis 19

When you can tolerate it. You may need to modify the wearing schedule a little when you first start wearing them until your Ciliary Muscles become stronger. I will advise you when you get those glasses.

Remember, that few people notice prescription changes, but almost everyone notices frame style changes.

If you order increasing prescriptions from a local, familiar lab, they may get curious about what you are doing. You need to think about that. One solution is Zenni Optical, if you can order from them.

By the way, your English is excellent. Have you studied English or are you using a translator program?


 19 Sep 2016, 13:16

Cactus jack,

My prescripton is:

R Sphere -3.25, Cyl -1.00, Axis 177

L Sphere -3.00, Cyl -1.00, Axis 19

As for the glasses

R Sphere -4.25, Cyl -1.00, Axis 177

L Sphere -4.00, Cyl -1.00, Axis 19

I can see very clearly with them and i nearly feel no strain on my eye at all though .. Every word is clear on my computer and i can read text every where easily.

Cactus Jack 19 Sep 2016, 07:20


Would appreciate the complete prescription. Every element is important.

Some questions.

1. How is your distance vision with them?

2. Are you able to read and use the computer comfortably with them?


Taha 19 Sep 2016, 02:01

Cactus jack,

Yeah they were not the right pair .. I got mine now and i don't really feel bothered at all .. It is perfect and i made sure the prescription is also right

Taha 19 Sep 2016, 00:24

I am going back to the lab right now .. I am pretty sure they must have given me the wrong pair .. Even the frame is a little different than the one i picked ..

Cactus Jack 18 Sep 2016, 16:59


What is the complete prescription in those glasses?


Taha 18 Sep 2016, 15:29

Cactus Jack,

I have just recieved my new glasses .... they are not bothering me alot .. but I can't see far away text ....

say i typing on my computer ... I can't see the text clearly when I sit a little far away ... say 70 cm and the font is about 8 .... I can live with it but is that normal ?

Taha 18 Sep 2016, 08:43

Cactus jack,

No, he didn't unfortunately ... he said that the military will give me a proper examination because i should be an officer because I am an engineer.

Cactus Jack 18 Sep 2016, 07:56


I suspect that part of your Myopia is Pseudo Myopia. The reason I think that is because your prescription decreased while you were wearing your old glasses. All that means is that you may need to work a bit harder to Induce additional Myopia.

I have another question: Did the examiner dilate your eyes for the very recent exam?


Taha 17 Sep 2016, 08:16

Cactus jack,

Sorry for the late reply, i had my examined today and the doctor found out that my -3.75 eye has improved and is now -3.0 .. I immediatly ordered a -4.25 ,-4.0 glasses the lab was a little surprised by my order as it is not like the prescription but they agreed .. I will recieve my glasses in 30 hours starting now unfortunatly.

I read your paper yes and all your recent posts carefully .. I have a skype username: eng.muhammad.taha

one more thing i wanted to talk about .. I broke my last pair of glasses 4 month ago and i srarted wearing my spare glasses which are about -2.5 ever since ,because back then i didn't know my eyesight can improve or that i can induce myopia .. Do you think maybe that is the reason for the sudden improvement ?

Thank you again for your time

Cactus Jack 15 Sep 2016, 19:39


1. You could, but that will probably not be necessary. The vast majority of Myopia you will induce will be Pseudo or false myopia which will (ideally) slowly resolve back to maybe -5 each eye. I suggest you should not worry about Lasik until there is no risk of anyone changing their mind.

My most successful "client" (also an Mechanical Engineer) started at about -4.00 and was able to work up to the point where he was able wear -20.00 glasses while studying. The military tried all kinds of tricks, surprise eye exams, etc., but while he did not wear the -20s full time, he wore glasses in the -14 to -16 range most of the time. I don't remember the details of our strategy for the actual exams, but the convinced themselves that he was not qualified and gave him an exemption. He ultimately settled back to about -5.00 in each eye.

2. Read the 2nd paragraph in my original reply to you. The military WILL use a very strong dilating agent, when they check your vision, to make sure you are not faking it. The technique that is typically used not intended to produce accurate results. It is fundamentally the "objective" part of an eye exam where the examiner looks into your eyes with an ophthalmoscope or retinoscope, after dilation, to get an estimate of your refractive error. They will skip the second or "subjective" part of an eye exam where you tell the examiner what you see with various lenses, where your actual corrective prescription is determined.

We really need to stay in close contact and you need to follow the suggestions without trying to go too fast. The objective is to first build up your accommodative range by increasing the strength of your Ciliary Muscles. In some ways it is like lifting weights. You don't build muscle strength by trying to initially lift 100 Kg. You do it by starting with 1 Kg weights with lots of repetitions. When the 1 Kg weights get easy, you switch to 2 Kg weights. Same thing here.

One thing you need to do, as soon as you can, is get a dilated exam to make absolutely sure of your actual prescription with dilation. I don't know if that will be possible for your Saturday exam.

Please remember that there are no guarantees that this will work, but it worth a try.

I have a few more questions.

1. Are you noticing any loss of distance acuity with your existing glasses?

2. Do you have Skype?

3. Have you read my piece on "How to study for an eye exam"

Please do not concern yourself about asking me questions. For this to have a possibility of working, we need to converse a lot. It is going require a lot of work and effort on your part.


Taha 15 Sep 2016, 16:05

cactus jack,

thank you so much for all this valuable info.

I have only 2 more questions please:

1- can I use lasik too restore my vision afterwards?

2- I heard the examination at our military is made using some sort of eyedrops and that it is not really accurate ... do you have any info. about this sort of examination?

I will do as you said, it is very easy to get any prescription that i want down here, absolutely no problem at all ... and if i have any further questions I will be sure to contact you ... and I will post any updates on my condition as well .....

I really can't thank you enough for your help :) ... god bless you

Cactus Jack 14 Sep 2016, 08:37


Your old prescription is good enough. It gives me a starting place. I understand the problem.

In some countries, they add the Sphere and Cylinder together to determine eligibility. I don't know about Egypt. Typically, when they do the eye exam for eligibility they use a very powerful dilating agent to temporarily paralyze your Ciliary Muscles, in addition to opening your pupils very wide. That makes the task a bit more difficult at your age, but it won't hurt to try.

We may be able to get you a little "insurance", but you need to be able to get glasses or contact lenses of any power without an official prescription.

There are actually two types of Myopia with two different causes, but the same result. You need corrective lenses. Axial or True Myopia is caused by a mismatch between the total power of your eye's lens system and the length of your eyeball. Axial Myopia is considered permanent because once your eyeball has grown a bit too long, there is no way for it to shrink. To Induce Axial Myopia, you need to encourage your eyeball to grow a bit. That is fundamentally controlled by your genes and once they have turned off the growth process, we don't know for sure how to turn it back on.

Pseudo or False Myopia is caused by the Ciliary Muscles and Crystalline Lenses having difficulty fully relaxing for distance after focusing close for an extended period. Pseudo Myopia is considered "temporary", but under the right circumstances, "temporary" can be a relatively long time.

The idea behind trying to Induce Myopia is to first cause Pseudo Myopia and the focusing stress from that will stimulate the production of an (suspected, but as yet un-identified and un-proven) Eyeball Growth Hormone (EGH). More about that later.

The first thing you need to do is get some glasses with more MINUS Sphere correction. Never try to alter your Cylinder or Axis correction for Astigmatism, it has a different cause and you cannot compensate for incorrect Cylinder and Axis.

Your present prescription is:

R Sphere -3.25, Cyl -0.75, Axis 170

L Sphere -3.75, Cyl -1.00, Axis 20

I suggest starting with a -1.00 increase in Sphere in both eyes, as soon as you can, which would result in:

R Sphere -4.25, Cyl -0.75, Axis 170

L Sphere -4.75, Cyl -1.00, Axis 20

You will need to wear them full time. Initially, you may have some mild discomfort wearing them for close focusing, but that will go away as your Ciliary Muscles get used to the additional accommodation. When you get comfortable with that prescription, you will need to increase the Sphere some more. You will be changing your glasses prescription much more often than usual to maintain the focusing stress. The trick is to keep the same frame style (preferably inexpensive) throughout the process. The reason for doing this is that most people don't notice your actual prescription, but the do notice changes in frame style.

A good source of inexpensive glasses is Zenni Optical, but I don't know if you can order from them, where you live.

I suggest reviewing this paper:

to give you a better idea about the physiological and optical principles involved.

Sir Isaac Newton's principles of optics that you probably leaned in Physics will also com in handy.

Please let me know if you have any problems understanding any of this or if you have any difficulty doing it. If you wish to contact me privately you can do so at or on the Vision and Spex website.


Taha 14 Sep 2016, 04:47

thank you for the quick reply cactus jack :) ... unfortunately I can't get my new prescription until next saturday ... I had my last prescription about 2 years ago and my doctor said that my eyesight has stabalized and I didn't feel like i needed any other glasses since then.

I am from Egypt and if my eye sight is not -4 at least before I graduate, then I will waste about 3-4 years of my life at the military doing nothing useful ... so getting the -4 is like saving my future now ...

sorry for the long long post :D ... here is my old prescription

... I will upload the new one as soon as I can ... thank you very much for the help ... you are lifesavers literally :)

Cactus Jack 13 Sep 2016, 09:18


Yes, but you need to get started as soon as you can.

Can you provide your complete prescription? You will need to start wearing glasses that have significantly more MINUS than you are presently wearing, but you need to do it the right way.

I have been able to help others with similar needs.


Taha 13 Sep 2016, 06:27


I am taha ..I am a mechanical engineering student .. I spend most of my time in front of a computer screen .. I am almost 24 years old .. My eyesight is -3.75 , -3.25 ... i need to make my eyes -4.0 .. At least one eye a year from now ... Is there a good chance i can do this .. I will be grateful if i can get any advice .. This is really urgent

Soundmanpt 11 Sep 2016, 10:04


Great question! But I really don't think there is any chance that you can induce any myopia at this stage of life. Now you didn't say when you started needing glasses again. Also I am curious if you got an increase at your most recent eye exam? It's interesting how many people pay lots of good money for lasik and then after a few years of being glasses free decide they want to wear glasses again. Several years ago a rather good friend that just happened to be an optician as well as manager of an optical store did just that. She was working at another optical store at the time and she had a prescription of -5.00 ish with astigmatism. In her younger years she had abused the use of contact lenses and could no longer wear them. She got the chance to get lasik for a greatly reduced price and had it done. The result was that she was able to see better than 20/10. After about 5 years of being glasses free and still having 20/15 vision she told me that she really missed wearing glasses. Not long afterwards she managed to convince her doctor that she was having issues with driving at night and he gave in and prescribed her -.50 glasses for night driving. Of course her intent was to wear her glasses full time which she did. 3 years later her vision was still good at 20/40 and that is even after having a baby. This was all before she was 30 years old.

Cactus Jack 11 Sep 2016, 09:38


You are much too old to be able to induce any True Myopia. You might be able to Induce some Pseudo Myopia, but at 41, presbyopia may make that difficult.

You can certainly wear glasses with your current prescription and maybe a little stronger. Maybe -1.50 and -1.25 or -1.75 and -1.50.

May I as your prescription after Lasik?


Serge 11 Sep 2016, 07:17

Hi, I had a Lasik operation back in 1999 when I was 24. My prescription was -4,75 and -4,25. Recently I had an eye test, the result was -1,25 amd -1. Would it be possible to induce some additional myopia wearing glasses fulltime, or should I wear them only for cinema etc?

Soundmanpt 10 Sep 2016, 10:17

I just went back and re read your first post and I see now that you don't glasses that are -1.50 but instead you were wearing contacts that were -1.50. But for whatever reason you didn't keep up wearing them. Why did you stop wearing them? So I have several questions concerning your use of contacts. First of all I assume you must have gotten the contacts from a friend? Ho long in terms of days did you wear them and how long each day? How well were you able to see with them? I would assume when you first put them on they felt a little strong for your eyes but after you had them on for a while your eyes adjusted to them? Were you able to read things close up okay with the contacts on? If you were to order glasses on line would your eyes be okay with -1.50 lenses or based on the contacts would your eyes be more comfortable with starting off with weaker glasses like maybe -1.00?

Soundmanpt 09 Sep 2016, 17:26


First of all trying to make your eyes nearsighted so you need to wear glasses is a decision that only you can make. If you are successful at becoming nearsighted it would be permanent and the only option to return to perfect vision would be lasik. But actually because of your age being 27 the chances of you becoming myopic are not really very good. Now I never want to say that it's not possible for you manage some change in your eyesight but just not very likely. And if you want to reduce the odds even more all you need to do is only wear your glasses about 75% to 80% of the time. If you go back in this thread and read about others that have wanted to "induce myopia" the main thing is the importance of wearing your glasses from the minute you open your eyes in the morning until you close them for bed that night. Anything less will make it far less possible to induce any myopia at all. If you have perfect eyesight now and chances are you won't be needing glasses to correct nearsightedness when you get older. But you can expect to start needing glasses for reading anytime after you reach 40. But I think what you're really wanting is feeling that you really need glasses to see distances. And that was what I was trying to tell you in my last post. If you like the glasses that you bought with the -1.50 lenses and your able to see with them perfectly not only for distance but close up as well then you should probably just make those your glasses and start wearing them as such. Your eyes will adjust to them and your eyes will actually be using the prescription of the lenses to see things. You will clearly notice the difference anytime you take your glasses because everything will be quite blurry for several minutes before your eyes slowly return to normal. The nice thing for you since you seemed concerned about permanent damage to your eyesight is that you should be able to wear those glasses without doing any harm to your real eyesight. But again you can expect that if you wear your glasses for several hours then take them off things will be blurry until your eyes return to normal.

Emma 09 Sep 2016, 16:12

Is it bad I want to be shortsighted? There's a lot of people that being shortsighted and I'm lucky to be ok. If I start wearing the the glasses would I always have to wear them like would my eyes get shortsighted and allyway need them? What prescription could I get too in a few years? Or is there a chance I will get shortsighted when I get older?

Yes I have a aunti who is shortsighted and some cousins that wear glasses for driving

Soundmanpt 08 Sep 2016, 21:41


I agree with Cactus Jack that at the age of 27 it is probably too late for you ever become myopic. But it seems that what you really are wanting is to be wearing real glasses with prescription lenses as opposed to glasses with no prescription in them. I totally get that you would find them boring to wear. But you have 2 options. One is since you already have glasses that you ordered that are -1.50 which is really a nice decent prescription for your eyes as long as your eyes are able to tolerate the the prescription okay. You could start wearing them tomorrow if you wanted to. The other option is to do like Cactus Jack suggested and that is to go on line to someplace like "" and order 2 pairs exactly alike but with 2 different prescriptions. Either way the first step is for you to start maybe mentioning to all your friends and co workers that you got your eyes checked and that you're going to be wearing glasses as soon as they come in. That way you can already be wearing them around the house to get used to them as well as your eyes adjusting to them. Them after 4 or 5 days just get get up one morning and put your glasses on and head to work. Even though you really want to wear glasses it's not at all surprising for you to be a little bit scared wearing glasses in public for the firs time. But trust me by telling people in advance that your getting glasses will make it so much easier when you start wearing them and try and think about how you reacted when someone you know got their first glasses. All that is going to happen is that your sure to get tons of complements on how good you look wearing glasses and many of the women will want to try them on. You will be the center of attention for about 10 minutes until everyone goes back to work and that will be the end of it. From then on everyone is just going to expect to see you wearing glasses.

Oh and your glasses will be functional. Your eyes will adjust to your glasses the same as if you really needed them. And you can expect that anytime you take them off things will be blurry for at least several minutes without your glasses until your own natural eyesight slowly returns.

Cactus Jack 04 Sep 2016, 08:38


Here is some good news and some bad news. At 27, you probably cannot induce any Axial or True Myopia. However, you probably CAN induce some Pseudo or False Myopia. The two different types of Myopia have different causes, but the effects are the same, you need to wear MINUS glasses to correct either type.

Based on the results of your eye exam, I am going to assume that you don't have enough Astigmatism to be a problem. Also, you mentioned having some -1.50 glasses.

The first step is to wind up with two pair of glasses with identical frames. You don't want to spend very much money, because you will be wearing them for only a short time. The lowest cost glasses from Zenni (US$6.95) or other online retailer would be ideal. Because of your age, you should be able to get used to wearing the -1.50 glasses in just a few weeks and be ready to move up to -2.50. By having identical frames, very few people will notice the increase. The important thing is to start off wearing the -1.50 glasses full time, when you are awake.

It is natural to be concerned about appearing in public with glasses. In reality, it is no different than getting a new hair style or a new outfit. The comments will only last for a few days. You should not offer any kind of explanation other than you had noticed that you were having trouble reading distant signs or menu boards. You don't need to and should NOT over state by saying that you are "blind" without your glasses. Even people with very high minus prescription are NOT "blind" without their glasses. If you want to get an idea about what it is like to be Nearsighted and need MINUS glasses, try on some different power Over-the-Counter (OTC) Reading Glasses. Wearing +1.50 reading glasses has the same optical effect as needing -1.50 glasses.

Here are a few more questions:

1. What is your occupation?

2. Where do you live? (country)

3. Do any of your close relatives wear minus glasses?

Hope this helps.


Emma 04 Sep 2016, 01:48

Now I'm 27 so if I stuck wearing the contacts and then glasses I would be nearsighted and blind without them now. I wasn't sure what people would say if they seen me wearing glasses probably to shy. But now I don't care because lots people wear glasses and they look good if your nearsighted.

Likelenses 02 Sep 2016, 19:22


If you want to wear glasses for shortsightedness,wear glasses rather than contacts.

Why did you give up on the -1.50 glasses?

Cactus jack 02 Sep 2016, 05:57


Creating Myopia is what this thread is all about. There are several factors that influence your ability to Induce Myopia, but the most important for now is your age.

There will be come more questions after you provide your age.


Emma  02 Sep 2016, 00:57

I've wanted to wear glasses for a few years now. I bought a pair from a opticians with clear lenses but they boring. I went to the opticians had a eye test and I don't need glasses. I know this is really stupid but i want to be shortsighted. People say it's horrible to be shortsighted but I like the way glasses look. Should I wear contacts to start my eyes getting shortsighted I once wore -1.50 lenses but didn't keep it up

Soundmanpt 20 Aug 2016, 10:48


I just noticed that I made a mistake in my post. (I know hard to believe that I would make a mistake) Anyway near the bottom it should have said that changing your lenses would be done at NO cost to you.

So I assume you were at least happy because I know you mentioned once about a frame that you had your eye on and you must have really liked them because you even said that you might go full time glasses and not bother with contacts anymore. So it would be nice if you could also get the lenses made in -3.25 which you were already wearing comfortably. I'm sure if you go back complaining nicely that your glasses seem too weak and that you just aren't seeing as well as you were with your partners glasses they will go ahead and increase your glasses.

 20 Aug 2016, 05:19

naaaaaaa who would go schizoid psycho and post as multiple characters here?

Cactus Jack 19 Aug 2016, 18:34


Haven't heard from you in a while. How are you getting along?


Soundmanpt 19 Aug 2016, 16:50


Okay so I see that you took my advice and wore your -3.25 glasses that you bought on line but told the doctor that you were borrowing your partners glasses. And they provided you with nice sharp vision. He even admitted that you probably needed an increase but declined upping your prescription because you may be dealing with long sight issues in the next few years. What I would suggest to you is that after you get your new glasses with the same old -2.50 lenses jsut wait a about 2 - 4 weeks and call where you got your eyes exam and I assume glasses from as well and complain that you're having difficulty seeing clearly when you drive with your glasses because they really seem too weak for your eyes. By doing that the doctor will have no other choice but to increase your glasses most likely to the -3.25 that you came in wearing. He will just assume that you wore them long enough that your eyes don't want to accept a weaker prescription. They will simply remake your lenses at cost to you. Trust me this will work if you prefer the strong glasses.

I posted a few weeks ago about wanting to achieve a higher prescription at an eye test. I wore a pair of -3.25 glasses, explaining that they were my partner's pair of specs and that I've been wearing them for a few months because they make my vision sharper. After the eye test, the optician explained that my prescription should probably increase but he wasn't going to do it because "age-related" longsightedness would probably kick in within the next few years. Argh! Not only does that make me feel old, but I'm left with my original prescription (-2.50). It's fine though - have ordered new glasses in -2.50 and am comfortable wearing them all the time instead of my contacts

I posted a few weeks ago about wanting to achieve a higher prescription at an eye test. I wore a pair of -3.25 glasses, explaining that they were my partner's pair of specs and that I've been wearing them for a few months because they make my vision sharper. After the eye test, the optician explained that my prescription should probably increase but he wasn't going to do it because "age-related" longsightedness would probably kick in within the next few years. Argh! Not only does that make me feel old, but I'm left with my original prescription (-2.50). It's fine though - have ordered new glasses in -2.50 and am comfortable wearing them all the time instead of my contacts

I agree with Cactus Jack,If you got a pair of glasses and you both wear glasses full time while at home.

If you could convince her to wear them for reading,and computer work,she may then find an even stronger minus for distance really comfortable.But if you do that,go with only minus one,and if successful,later bump her up,but do not get too aggressive.

Cactus Jack 16 Aug 2016, 12:16


One of the things I learned about Leadership, many years ago, is to never ask someone to do something you are not willing to do yourself. I would suggest that the approach you are taking as that of a Manager. In other words: "Don't do as I do, do as I say". Generally, a managerial approach does not work with those who are very close to you.

I believe you said that you do not wear glasses. As a suggestion, you should consider getting glasses that you can wear full time. We'll be happy to help. You might find that setting the example works wonders.

I've found your story of trying to get your wife to wear minus glasses very interesting.

Can I ask you how did you break it to her the first time when you bought her the -50 glasses and gave them to her? What did you tell her? Did you actually tell her that seeing her wearing prescription glasses turns you on? Or did you stage it like a game? What was her reaction?

And what about when you gave her the -2 glasses? What was her reaction? Did she find it natural?

How long have you been together?

Sorry if I'm being too nosy. I think a lot of us relate to your story as we would like to be able to make the step you've made with your wife.

Soundmanpt 13 Aug 2016, 10:14


Well of course she is only wearing them to please you since her eyesight is perfect. And even then she only wears the glasses because she is able to see perfect wearing them. If she were really interested in wearing glasses she would have made more of an effort to wear the -2.00 glasses. But those glasses were forcing her eyes to work to focus with them. Since she clearly doesn't have any real desire to wear glasses she likely was afraid that the -2.00 would ruin her eyesight and she might then have to wear glasses. She has found that wearing the -.50 glasses hasn't had any real effect on her eyes so she is willing to wear them to please you. Her eyes are really comfortable wearing the glasses which explains why she forgot to take them off after the movie ended and walked several blocks wearing before she realized that she still had them on. It seems you're going to have to settle for seeing her wearing her weak glasses when your both watching TV or at the movies. Sadly she seems extremely about being seen by anyone while she has the glasses on. It is very normal for some to be shy when they first get glasses around family and friends, but most are okay around people they don't know. The fact that she refuses to be seen wearing glasses at a restaurant that is far away shows how shy she is. Is there someplace she has said how much she would really like to go? Maybe in a rather joking way you can say "well it's possible that could be arranged if you were to wear glasses the whole time we are away". What about some type of get away to a quite resort where it would be mostly just the 2 of you. That might sound romantic enough to her that she might be welling to wear glasses. Good luck!

Eric 13 Aug 2016, 06:20

Thank you for your responses. She has never wore the glasses in public. She only wears them outside home when we go to the movies. She takes them in her purse and puts them on after the lights are turned off. When the movie finishes, she takes the glasses off. She wears them only because she likes the special attention she gets from me. Once she forgot to take the glasses off and we walked about two blocks until she noticed it, and she was angry I didn't tell her she forgot to take them off. Sometimes when we go to a restaurant that is far from home I try to convince her to wear the glasses there. But she never wants.

I don't wear glasses.

Cactus Jack 12 Aug 2016, 07:32


At 30 it is very unlikely that she can induce any Axial or True Myopia, the permanent kind, where the eyeball actually grows.

She might be able to induce some Pseudo or False Myopia, the temporary kind. Pseudo or False Myopia is an optical process that involves using the Ciliary Muscles and Crystalline Lenses (your auto-focus or Accommodation system) to add PLUS, internally, to neutralize the excess MINUS in the glasses. Two things limit how much of that you can do. Presbyopia and the strength of your Ciliary Muscles.

Presbyopia is a natural process that affects almost everyone. It is the gradual stiffening of the protein of your Crystalline Lenses as you get older. It actually starts in childhood, but usually does not become a problem until the late 30s or early 40s, but the age where it becomes a problem depends on your actual refractive error and your visual environment.

The strength of your Ciliary Muscles depends on how much you exercise them. For their size, very tiny, they are the strongest muscles in the body. Exercising them is very much like going to the gym and doing muscle training. The best way to build muscle strength is by gradually increasing the weight you are lifting and doing lots of repetitions, rather than trying to lift very heavy weights, too soon. The same principle applies here. The -0.50 increase was a good place to start, but she really needs to wear them a lot. When those get comfortable switch to say -1.00 or -1.50, and then to the -2.00. Remember, the key is that she gets both visual pleasure and other pleasures from the process. You likely know what to do about the other pleasures.

As far as wearing the glasses in public, every new glasses wearer goes through that. Typically it only lasts for a day or two. For the ladies, it is simply like getting a new hair style. A few comments until everyone gets get used to it and then nothing. All you have to say if someone asks about your glasses, is that you were having trouble with your distance vision and the glasses make thing really sharp and clear. If they try the glasses they may comment that the prescription is weak, but don't let that bother you. If a person needs -0.50 glasses, that means that without them, everything beyond 2 meters or about 6.5 feet is fuzzy.

BTW, most people only notice the frames, not the actual prescription in the lenses. The trick for increasing the prescription without comment, is to use the same frame for all the increases.

A question for you. Do you wear glasses?


Soundmanpt 12 Aug 2016, 07:19


Well you did so good by starting your wife off with a nice weak -.50 glasses. I'm sure those glasses were very comfortable to her eyes and in fact even with her perfect vision with those glasses she can actually see slightly better than perfect (20/20) and if she were taking a vision test wearing those glasses she would be able to the 20/15 (better than perfect)So I am not at all surprised that she could read the subtitles so well. She is actually seeing them better with those glasses. She probably doesn't notice it because she is only watching the TV from a rather short distance away so when she takes off the glasses after wearing them several hours she probably doesn't notice it because of the short distance but if sh were out looking at a much greater distance she would notice a slight blur when she takes the glasses after wearing them. The blur would only last a few minutes and her natural vision would return. By getting her -2.00 glasses you were being too aggressive with her eyes. That's a pretty big jump because remember her eyes never really fully adjusted to the -.50 glasses, but her eyes were just able to tolerate them without any problem. Also with her already being 30 her eyes are almost certain to be stable so there is hardly any chance of her eyesight being changed by wearing glasses. And even if she was say 18 or 20 she would have to wear glasses from the time she opens her eyes each day until she closes them at night to induce any myopia. Wearing glasses for a few hours in the evening while watching TV would have no permanent effect on her eyes. Now if you're able to convince her to wear glasses much more often or even full time she should be able wear those -.50 and see better than perfect for everything she does now without glasses. If those glasses have AR coating she might even find that they are very comfortable to her eyes when she is driving at night Now you can experiment to see what the limit that her eyes are comfortable wearing might be. I would suggest getting her a pair of -1.00 glasses and see how she likes them. Remember if she, or her eyes, aren't comfortable wearing them she is less likely to want to wear them. She must know that you would really like to see her wearing glasses all the time? Maybe a compromise is in order since there is very little chance that she is ever going to be really nearsighted. Try and get her more comfortable wearing her -.50 glasses in public more often. One thing is that she is probably like many that get glasses for the first time in that she is shy about being seen by her friends wearing glasses for the first time. maybe a good start would be to take a nice weekend get-away but convince beforehand to wear her glasses the whole time you're away. She isn't going to nearly as shy about wearing glasses if she doesn't know anyone.

Eric 12 Aug 2016, 02:43

Hello to everyone. My wife is 30 years old. She has perfect vision. Everyone in her family are myopic, except her. Once she tried her sister and her cousin's glasses and I loved how she looked.

Since then, I bought her a pair of -0,50 glasses. She is very shy about wearing them in public, so she wears them only at night when watching a movie at home. She doesn't need them, but she knows it turns me on. They don't make her feel dizzy and she says she can read the subtitles without any problem. So she wears them every night for about 2 or 3 hours.

Three months ago, I bought her a new pair, a -2 glasses. I makes me crazy to see her eyes through that cut in. Every time she wore them, the most she could stayed with the glasses was 10 minutes. She says that forcing a little her eyes, she can focus on the subtitles, but that after a while she feels dizzy.

I would love to see her wearing those glasses always. Is there any way to help her acomodate to those glasses? Any way to help her eyes feel relaxed with them? I know every person is different, but which is the estimated maximum amount of prescription that someone with perfect vision can handle without any trouble? Is there any chance at her age (30) of becoming myopic?

Thank you.

Soundmanpt 10 Aug 2016, 09:48


It seems like before you got started with trying to induce you did some research in this thread. For someone with near perfect eyesight you didn't go too strong for your first glasses which is the best way to start. But like Cactus Jack said now that your eyes are completely comfortable wearing -1.50 glasses, it's time for you to order new glasses with -2.50 or -3.00 lenses. Since you have only been wearing glasses for about 2 months if you get a completely different frame you might get questioned why you need new glasses already? If you're a female you might just say that you wanted a 2nd pair to wear with different outfits. Or if you don't want anyone to know then you maybe able to order the exact same glasses as your current ones in the stronger prescription.

I understand that you want to be able to go for an eye exam and only be able to see a few lines on the eye chart and be given a prescription slip for glasses. The only reason to induce myopia is so you need glasses. But even without any actual change in your eyesight, you're wearing glasses with prescription lenses and with them you see perfect and when you take them off things are blurry, the same as if they had been prescribed to you.

What was the reaction you got when you first appeared wearing glasses? I'm sure you had a number of questions to answer. Does anyone know what you're doing like a girlfriend or boyfriend?

Cactus Jack 10 Aug 2016, 06:41


Two months is probably not long enough. If the -1.50 glasses are comfortable, you need to consider -2.50 or -3.00.

Auto Refractors are not always very accurate because they only do the objective part of the exam and not the subjective part where you have to tell the examiner what you see. Most examiners just use them to skip the objective part of the exam and use the printout as a starting point.

May I ask a few questions?

1. your age?

2. Your occupation?

3. Where you live? (Country)

4. What is your goal?


Fry 10 Aug 2016, 05:26

Cactus Jack

Thanks for your answer. Ive been inducing for about 2 months now. i use OD and OS -1.5. My eyes are comfortable w/ the glasses on. After using the glasses, i notice that my vision is blurred w/o the glasses, so i continued using it. A few hrs ago, when i was at the mall i saw a free eye exam so i took off my glasses and went in for the exam. After that the optometrist said that i do not need glasses yet bec my prescription is just -0.25 for both eyes which is my original prescription. but w/o the glasses im using for inducing, my vision is blurred estimately for things that are a meter away from me.

Cactus Jack 10 Aug 2016, 04:42


If you are successful, an auto refractor will detect it.


Fry 10 Aug 2016, 04:31

Hi. i have a question, if i tried inducing myopia for several months for example. Will the autorefractor detect the change in grade or it will not show up and just base it on manual refraction?

Soundmanpt 05 Aug 2016, 12:01

Well I don't where you live but in the US if you go into any boutique store for women you're going to find several racks with fake glasses on it. Even more fake glasses then sunglasses. So that alone should tell you that now many young ladies really want to wear glasses for fashion even if they don't need them. The problem is when a young girl or woman buys a pair and wears them and someone asks about their glasses which is sure to happen if she has never been seen wearing glasses before as soon as she admits that the glasses or jsut fakes she often times gets "outed" for wearing fake glasses by anyone that really wears glasses. So for that reason alone I have sold glasses to a number of young ladies (over 18) with a very weak prescription in them so they aren't wearing fake glasses. Now of course that doesn't answer your question about why stronger glasses. I think it has to do with the blur factor. Very weak glasses have hardly any blur factor when you take them off, but the stronger the glasses the more the blur. Some people really enjoy that blur. so when that person wearing -2.00 glasses takes them off he or she gets some blur of course but can still make out things quite well without glasses, but when you get to -6.00 now things are much more blurred without their glasses.

I have a friend that recently graduated from optometry school and she just moved to another city to start as an eye doctor. When I met her she was working as an optician at a local shop. Not long after I first met her we were talking and I was curious why she wanted to be an optometrist since she had already told me that she had perfect vision. in our conversation she admitted that she even tried wearing an old pair of her sisters glasses just to see what it was like but her sister has astigmatisms and all she managed to get was a headache. Anyway I asked her if she ever heard of GOC and she had no idea what it was. I didn't tell her but I had her pull out a pair of trial lenses in +1.25 and i went to my car for a really cute pair of glasses that I had and I had her put the lenses on and of course with the lenses on her vision was no longer perfect and I watched as her eyes were attempting to focus with the lenses. I then told her I was going to give her perfect vision and put the glasses i was holding on her. They were -1.25 and she was amazed because now she was again able to see everything clearly but only because she was wearing glasses. She was so shocked but she totally enjoyed everything about it. For her it was a real education for her about eyesight. At one point she took the glasses off and I watched her squinting quite a bit trying to make out what a sign said across the room. After a bit she put the glasses back on and so she could read it and then she told me that she always wondered why when people came in while she was adjusting their glasses she would she them squinting and she wondered if that really helped and she was surprised that squinting did help but it was still blurry even with squinting. She was having such a good time wearing glasses that I left her borrow them and I never got them back for over 6 weeks. She told me recently that she got glasses made up in -2.50 which she plans on wearing quite a bit while working because she thinks being a doctor now she should be wearing glasses. She likes the blur she gets when she takes her glasses off. But she isn't doing an harm to her eyes doing this method.

Nitai Duchan 05 Aug 2016, 10:53


Also another thing I forgot to ask you.

If you already have glasses, why would you want stronger prescriptions?

If you have -2 glasses, why would you want -6 glasses?


Nitai Duchan 05 Aug 2016, 10:42


But what are the reasons they want glasses? To look smarter? To look nerdy?

DS 04 Aug 2016, 09:31

At least changing vision is fully correctable, unlike the other things you mentioned. I don't know where I would rank this compared to piercings and the infection risk from that.

Yes, it does seem odd, but to each their own, especially if there is no real harm.

 03 Aug 2016, 19:21

How would we react if a friend or loved one purposely started to ruin their hearing to wear a hearing aid or repeatedly break limbs to get casts? People actually do these things too. They would not be hurting anyone else physically either.

Soundmanpt 03 Aug 2016, 13:31

Nitai Duchan

Your question is a fair but I guess its like the the guy that just a few days ago jumped out a an airplane without a parachute from 25,000 feet (nearly 5 miles) into a net that was only 100 feet square. Why did he want to do that? I certainly would never do that but to each his or her own. I get it there are many people that need and wear glasses and hate wearing them and wished they didn't need them. But there are also quite a few that wear glasses that they need and they love wearing glasses. And lastly there are those that maybe might have perfect eyesight but have always had the desire to wear glasses. For them wearing fake glasses isn't the answer and for good reason. they don't want to be teased by others for wearing fake glasses. Are you really ruining something if you're able to fix it or correct it? So even using the example you pulled out from 2002. He isn't doing any harm to anyone and even if he or she does induce myopia as long as they wear glasses or contacts they are are to see as well as anyone can. Again clearly this doesn't sound like something you're interested in doing and that's fine. It should be the decision of the person doing it. If this person wasn't happy with how their eyesight was after starting with -2.00 glasses they could have stopped then if they wanted.

Nitai Duchan 03 Aug 2016, 12:38

Can someone please explain me why would anyone want to INDUCE myopia? Why would someone want to ruin their vision?

Look at this comment from 2002 in this thread:

"Having tried it all I started faking prescriptions with -2's after a few months of getting used to it then -4's, now I am at -6's. I can see perfectly with the 6's and when I take them off my eyes seem to hold the prescription for about 10 minutes or so then (unfortunately) slowly start to drift back to normal"

Why does this guy want to get myopia?

Cactus Jack 30 Jul 2016, 09:22


You followed the rules about only changing the Sphere correction for getting stronger glasses.

IF the glasses were made correctly, you should not have much problem, at 31, dealing with a 0.25 increase, unless you have early onset of Presbyopia. The clue to that would be if you are having trouble reading with your glasses on.

One possibility is that the PD (Pupillary Distance) is not correct. It is pretty easy to measure with a short ruler marked in mm and a bathroom mirror.

What was the source of the PD when you ordered the new glasses?

What was the PD you used?


mark 29 Jul 2016, 23:56


i m 31.

Cactus Jack 28 Jul 2016, 13:25


Not enough information to offer an answer to your question. The following would be helpful:

1. What is your age?

2. What is your current complete prescription?

3. What is the complete prescription you ordered with -0.25 over correction?

4. Where did you order them?

Soundmanpt 26 Jul 2016, 12:49


I think wearing your -3.25 glasses and claiming that your friend loaned them to you to wear is the perfect way to get stronger glasses. You were at a lake and you forgot to take off your glasses and they fell off in the water. This happens all the time by the way. Even more often if drinking is involved. Everyone looked for them but they were never found. When you got home and told your best friend what had happened and how much trouble you were having trying to see with your old glasses because they were too weak she reminded you that when she had gotten her new glasses you traded glasses and found that your glasses were not too much different. So she got her previous glasses for you to wear until you could get a new pair. She said there was no rush to return them. But it had been several months and it was time to return them to her, so that is why you decided to get your eyes examined. But just keep raving about how well you can see with her glasses.

It's always interesting how someone suddenly becomes nearsighted late in their twenties or early thirties when they had perfect eyesight before that. You would think that staring at a computer monitor from the time you graduated would have put you in glasses much sooner then some ten years later. Just too hard to say for sure what caused your need for glasses. I don't think your eyes are capable of inducing enough myopia to get anywhere close to an actual prescription of -4.00. The basic unwritten rule of inducing myopia is based on age and it becomes harder and harder to induce any myopia once you pass the age of twenty, but with you first developing myopia when you were thirty doe make your eyes a bit different and I guess anything is possible just unlikely. If your able to get the doctor to write you a prescription for -3.25 glasses and that will allow you to get those glasses you have your eyes on I think that should make you a happy young lady. You said to "Bill" that your desired prescription would be -4.00. If you think about it -3.25 isn't that far from -4.00 anyway. You mentioned about how when you get up in the morning you don't reach for your glasses first thing and you don't even bother putting them on until you leave the house. The reason you don't feel like you need your glasses is very simple. Over night while your sleeping your eyes are going back to their natural state or better put your actual real prescription of -2.50 which isn't bad enough that you can't function around your house where you don't have to see very far away. But once you put on your -3.25 glasses and your eyes by now quickly adjust to your glasses. Now that your wearing your glasses your eyes aren't seeing -2.50 when you take off your glasses but instead they are seeing -3.25 without your glasses. That part of you that is attracted to needing your glasses full time is very real after you have been wearing your glasses for a while and try walking down a street without your glasses. No doubt that your eyesight is much more blurred than it was in the morning when you first got out of bed. So even though you really want to wake up feeling so dependent on your glasses that you need to reach for them as soon as you open your eyes each day. That just may not ever happen. But you need to know that their are some people with very real prescriptions of over -4.00 that don't bother putting their glasses on until they leave the house. And there are other with weaker prescriptions than -2.50 that put their glasses on first thing. They even have their glasses open sitting on the nightstand next to their bed. There's no reason you can't have your glasses open sitting on the nightstand next to your bed as well so you can put your glasses on right away. First of all if your really wanting to try and become more myopic if your not putting your glasses on first thing even before you ge tut of bed your not going to have any luck with inducing anything. Go back in this thread and you will see that besides age it is critical that your eyes are looking through prescription lenses every waking minute. Not putting your glasses on until you leave the house is far from doing that. When your wearing your glasses i'm sure that you must feel dependent on your glasses now and that is really all you really want is to be able to wear glasses that look rather strong and feel like you need them. I'm really glad you didn't have prisms added to your glasses. Being nearsighted is one thing but prisms when you don't need them would just completely ruin your eyes. Not only would you look cross eyed without your glasses but I don't think you would like seeing double vision anytime you took your glasses off. Also that would take away any chance of ever wearing contacts again. I know right now your wanting to wear glasses full time but you never know when you might want to go back to wearing contacts maybe for some special occasion. good luck with the eye exam.

Courtney 26 Jul 2016, 08:31

Soundmanpt - I'm definitely gonna try the 'borrowed glasses' trick you suggested - hope I can pull it off convincingly! I guess the deterioration in my eyesight during my 30s is down to my job - I've been pretty much glued to a computer screen (i.e. close work) during my work life ever since graduation.

Bill - ideally I'd like to end up with a prescription of -4 (or thereabouts). It's definitely the radical new look element of wearing glasses (i.e. shocking friends/family) that attracts me. But I want to do that with a significant prescription, otherwise I'd wear plano lenses like all the hipsters. There's also a bit of me that is attracted by needing them full-time too - even though walking down the street without correction is dicey (not to mention dangerous), I don't automatically reach out for my specs first thing in the morning (the glasses/contacts don't usually come on until I leave the house). I'd definitely like to reach that level of dependence. (To achieve the latter, I once thought about ordering prisms online but don't want to end up cross-eyed!). Ultimately I want people to view me as a full-time girl with glasses that actually needs them

Eye test has been postponed until next week - I'll let you know how I get on

Cactus Jack 24 Jul 2016, 06:29



1. The lack of cylinder will make your efforts easier. No astigmatism (cylinder correction) gives you a lot more flexibility because you can "stack" Sphere only lenses. For example, you can use Sphere Only Contact Lenses and Glasses together or in private, two pair of glasses, one on top of the other.

2. It was probably a good idea to go ahead and order glasses for parental and family reasons. They need to get used to your wearing glasses. In a couple of weeks they won't notice a small lens change if the frame is very similar. I hope you selected a frame that was not very expensive, identical or very similar to the -2.25 glasses, and similar to an inexpensive frame that is available from an online retailer, such as Zwnni. I suspect you will not wear the -1.75 glasses very long or very much because you have become accustomed to wearing the -2.25 glasses and you will likely notice the -0.50 reduction in the sharpness of your distance vision. I believe you mentioned that Scott had given you a bit stronger pair (-3.25?). Have you worn those very much? Is the frame similar? Remember, frame style changes will get you questions and comments. Lens changes, not so much, but sometimes people notice increased edge thickness or a change from a frosted edge (white) to a polished edge (clear).

3a. Lens thickness is a function of Prescription, lens width, and Index of refraction. The ideal lens material is CR-39 or similar. It has a low index of refraction (IR) (about 1.49) and excellent optical properties (abbe value). Avoid expensive high index lenses. Polycarbonate (Lexan) is OK, but it has a bit higher IR and is physically VERY strong.

3b. I believe you mentioned Scott's current prescription, but i don't remember it. Seems like it was in the low double digits. If you work at it, as you have these past few months, you should be able to work up to around -5.00 without too much trouble. I suspect Scott has progressive myopia and I suspect his prescription has naturally increased about 1 diopter per year, unless he has been consciously or unconsciously pushing it as you have. He could wind up in the mid to high teens before it stabilizes.

3c. The white edge is frosted as mentioned above.

3d. The "layers" are called Power Rings. They are actually internal reflections of the edge of the lens. The edge treatment affects the intensity of the reflection.

You can think of a lens as many very thin prisms, arranged in a circle. In a Minus lens the apex is in the center and the base is at the edge. In a Plus lens, that is reversed. The prisms bend the light rays toward the base of the prism.

3e. Depending on your Major and tendency toward Myopia (genetics), College can cause significant prescription changes. Most common are increases in Myopia and early need for an Add to help with close focusing and frequent switching from distant lecture displays to note taking.

When will your glasses be ready?

Did you ask about contact lenses. You may want to consider that as a convenient way to increase your prescription. If you wear -1.75 contacts and your -1.75 glasses together, that is -3.50 without being apparent to others.

Let me know if you have any questions that I can help you with.


CJ 23 Jul 2016, 23:08

Cactus Jack,

1. No

2. Yes

3. Get more myopia. I would love to need thick lensed glasses. I do not anticipate getying as neatsightdd as Scott, but even 3/4 or 1/2 of his would be great. His lenses are so cool. The way they look white from the sides, the way his eyes look smaller with them on, the way that at some angels and lighting the lenses look white, and the way you can see layers in the lenses. I want that at least to some point. Also, in college away from home it should be easier.

Cactus Jack 23 Jul 2016, 12:26


You did a very good job, congratulations. I hope our coaching was useful in helping you achieve your goal, but you did the work. I have a few questions:

1. Does your prescription include any Cylinder correction?

2. Did you order glasses?

3. What would you like to do as a next step?


Soundmanpt 23 Jul 2016, 10:37


Wouldn't you know it that whoever was entering your order was being very observant and assumed you made a mistake in ordering your glasses. I see that Spec4ever ran into the very same problem and convinced them that it wasn't a mistake. I hope you were able to do the same with them. I think they just want to make sure that you didn't make a mistake and once you tell them that you didn't make a mistake they won't ask anymore questions. Zenni claims that within 24 hours of receiving your order your glasses are finished, Your glasses are made in Hong Kong and then shipped to California. Then they are shipped from California to you.

CJB 23 Jul 2016, 10:30

Cactus Jack

It went great. My prescription is -1.75 in both eyes!

Specs4ever 23 Jul 2016, 06:50

Nix, I ran into the same problem one time when I was ordering 3 pairs of glasses with progressively stronger prescriptions. I stated, as you did, that the strongest pair was for distance, and the weaker pairs were for reading and mid range use. I simply told them that my eye doctor said that the reduction in pd fro reading and mid range was true for bifocal/trifocal wearers, but with glasses that are full field the wearer is looking through the center of the lens so it would be best to order the same pd for all 3 pairs. They accepted that.

Cactus Jack 22 Jul 2016, 18:54


How did the exam go?


Nix 22 Jul 2016, 18:44


Okay actually they emailed me and this is what they said..

Your order is being processed promptly, but we need to clarify something with

you before they can be processed further.

The PD is the distance between the two pupils, center to center. It appears that

the pair of #125415 (with Sph -1.25/-1.25) is single vision glasses for

reading/near correction, the pair of #125415 (with Sph -2.25/-2.25) is single

vision glasses for computer correction, and the pair of #125415 (with Sph

-3.25/-3.25) is single vision glasses for distance correction. Normally, the

reading PD is 3mm less than the distance PD, and the PD for computer use is 1-

2mm less than the distance PD. Will you please check with your optometrist and

email your correct distance and reading PDĄŻs to us?

Please email your confirmation to us and we will modify your current order with

the information you provide, so you don't have to place any other new orders.

Thank you for selecting Zenni Optical for your vision needs...

so um i just emailed back saying that its just the pd my optometrist wrote on my prescription..

Soundmanpt 22 Jul 2016, 18:35


Good to hear. I know you're anxious to get your glasses so you can start wearing them. I really do think you will get them before the 3 weeks they said to allow for delivery. Zenni will send you an e-mail when your glasses ship out. Now for me here in the US that always meant that I could expect the glasses in my mailbox in about 3 days. You know once you get that e-mail you can check the status of exactly where your glasses are very easily on line?

Nix 22 Jul 2016, 16:59


Hi! :) Yes Ive already placed my order and I am just waiting for it now. I used PayPal. I just feel it's safer to use since I am using a debit card.

I can't wait

Bill 22 Jul 2016, 02:35

Courtney, what prescription would you like to end up having ideally? Is it the look of wearing glasses or the thought of needing them that attracts you or both?

Soundmanpt 21 Jul 2016, 11:21


You're more than welcome and I hope my advice is helpful to you. I really think if you tell the doctor how comfortable your friends borrowed glasses (hee hee) are and how well you can see with them for the past several months the doctor isn't likely going to try and give you weaker glasses than your wearing.

So you never got glasses until you were around 30 years old. Much later than most become nearsighted. But because your first prescription was -1.50 you probably already should have gotten glasses when you were closer to 28. When you were 28 if you had gotten your eyes examined you probably would have been prescribed with glasses that would have been about -.50 or -.75. Do you recall if there was something you might have been doing that might have effected your eyesight in some way? I mean maybe doing lots of close work in dim lighting? It would seem that by the time you got your first glasses things should have been blurry enough that you might have expected that you going to be getting glasses. How did you figure out that you could order glasses on line and even get them made stronger? If you only wore your glasses part time for driving and watching TV for 3 years you didn't really seem to have a great desire to wear glasses which is often why people want to induce myopia. Even with your -2.25 glasses that you ordered on line were a strong enough prescription for someone to wear glasses full time if they wanted to. Now when you got prescribed your -1.50 glasses it's very possible that you were slightly under prescribed since these were your first glasses they didn't want to go too strong so it was easier for your eyes to adjust to them. So you very likely needed -1.75 glasses as your first ones anyway. And yes of course by wearing -2.25 glasses helped things along. But even if you had only wore your -1.50 glasses your eye were still changing so getting an increase after 18 months might have happened anyway. I think the only good thing contacts are good for is causing total dependence on either glasses or contacts. So not at all surprising that once you started wearing contacts you became dependent on either your glasses or contacts from then on. I kinda like the idea that your new look / identity will include you wearing your glasses full time from now on. You must really be in love with those glasses your after? I say "You go girl"

Courtney 21 Jul 2016, 10:15

Hi Soundmanpt, thanks for the advice. I really appreciate it. My first pair of glasses was around six years ago, when I was prescribed a pair of -1.50 glasses, but ordered a pair of -2.25 glasses which I wore for driving, watching TV etc. Around 18 months after that, my prescription went up to -2 (so I'd induced -50 within that time) and I decided to go full-time with (mainly) contacts three years ago when I was prescribed -2.50. Over the last six years, I think I've got to a point where I'm truly dependent upon glasses/contacts and wouldn't dream of leaving the house without wearing either.

I've always wanted to be a full-time wearer but when wearing my previous pairs, I've never seen 'me' when looking in the mirror. However, with this pair I've spied in the opticians, I'm really looking forward to experimenting with an entirely new look/identity.

Soundmanpt 21 Jul 2016, 10:01


Did you only first start wearing glasses 3 years ago or did you only start wearing glasses/contacts full time 3 years ago?

Generally speaking once you're past around your mid twenties your eyes become stable. So it is unlikely that wearing your -3.25 glasses and -3.00 contacts has actually changed your eyesight. But like most your eyes simply enjoy the over correction from the stronger glasses and contacts. And of course you really are seeing better with the stronger glasses and contacts as well. Then putting on your -2.50 glasses they are going to feel much weaker then the stronger glasses and contacts. It's very possible that when you're wearing the stronger glasses and contacts that your eyes are actually seeing 20/15. With your -2.50 you might still be seeing 20/20 but of course that's not as good as 20/15. One way you can wear your -3.50 glasses to your eye appointment if you want and it might even help you get an increase as well. Simply tell them when you go that you broke or lost your glasses and you were lucky that friend had her spare pair of glasses that you were borrowing and just rave about how well you can see with them. They will take your glasses to check the prescription of the lenses. So the doctor will already use that number as a starting point. Just continue telling the doctor how well you can see with those glasses and how you have never seen better with glasses before. With any luck he / she will just write you a prescription for -3.50 since you're so happy with those glasses. Then you buy the glasses you have your eye's on. Dumping the contacts and wearing your new glasses full time which i'm sure you're going to be getting sounds like a good idea. Besides there isn really no point in inducing myopia if you're wearing contacts. The whole idea of inducing myopia is so you can wear glasses with stronger lenses.

Courtney 21 Jul 2016, 09:10

Thanks all. I've been wearing contacts/glasses (mostly contacts) full-time for around three years now (I'm 36).

I ordered my last pair of glasses online - as I wanted to induce more myopia, I ordered a pair of glasses last year which are -3.25 in each eye and -3 contacts (my real prescription is -2.50). Now, whenever I wear my -2.50 pair, things in the distance are nowhere near as sharp as when I'm wearing the -3.25 pair. Maybe I should show up for the eye test wearing the -3.25 pair? I don't know whether I've induced -0.75 of myopia in one year, but you never know!

I've seen a pair of glasses in the opticians that I really want. I'm so fond of this pair (have been into the opticians many times to try them/take selfies), I may even consider forsaking the contact lenses for good!

Soundmanpt 21 Jul 2016, 08:34


The post on "How to Study for an Eye Exam" that "Cactus Jack" is suggesting you read is well worth reading before you go for your eye exam.

Is there a reason why you're wanting an increase in your prescription? You're at -2.50 in both eyes so I would have to assume that you wear your glasses, or contacts, full time already? Is there any reason to think that your eyes may not need an increase without you even doing anything except being honest? If you normally get small increases every year and you got an increase at your last exam chances are you will get another increase. Also if you simply tell the doctor that you feel like your glasses aren't strong enough and yo feel like you're straining to see things at a distance even if you don't need an increase almost always the doctor is going to want you to leave happy so he / she will increase your glasses a bit.

You know you have another option as well. You can go for your exam and if there hasn't been any change in you eyes simply go on line and order your glasses that way with no questions asked. So you go in there today and pick out glasses you like and instead of ordering them with -2.50 lenses just go whatever you want. If you're only wanting a small increase or change in your glasses then I think -3.00 would be perfect for you and you should be able to adjust to that prescription rather easily.

John S 21 Jul 2016, 08:22


You could also come into the office wearing sunglasses. That would explain the marks from the nose pads, and also let you wear Scott's glasses right up until the exam.

Good luck

Cactus Jack 21 Jul 2016, 04:00


Clearer, but don't push it to much. Have you read my post "How to Study for an Eye Exam?


Courtney 20 Jul 2016, 23:08

Hello, have an eye test scheduled for next week and want to walk away with a slightly higher prescription (am currently -2.50 in both eyes). I know all about opting for red over green, but what should I say if they ask me, "are the letters smaller or clearer?" Which one should i go for? Smaller or clearer?

Cactus Jack 20 Jul 2016, 21:03


That is true, in the meantime, you can't hurt anything by reading as much as possible. If you can wear the -2.25s stop a few hours before the exam and massage your nose where the glasses rest on it.

Think about future strategy and plan for it.

Wish you the best and look forward to the results. Will be out of pocket most of Thursday.


CJ 20 Jul 2016, 17:27

Cactus Jack

I will find out in less than two days anyways.

Cactus Jack 20 Jul 2016, 09:36


You can do the test without the +1.50 glasses, if you have developed enough myopia to make the distances involved and the text size manageable.

Without the +1.50 glasses, you will need to use a bit larger text and be able to deal with the longer distances involved. Your clock might work, but if the numerals are not black on a white background is may reduce the accuracy of the test.

All you have to do is measure the distance where small elements in the "target" just begin to get fuzzy and use that as the denominator in the Lens Power = 1 meter / Focal Distance.


CJB 19 Jul 2016, 14:25

Cactus Jack,

Thank you for the tips. Yes I have read you post about studying. I cannot find the +1.50 glasses, or else I would do the test.

Cactus Jack 19 Jul 2016, 08:56


I don't think you have anything to worry about for your Eye Exam.

You might consider doing the test again with the +1.50 glasses and letting me know the results. The only purpose of the +1.50 reading glasses is to make you optically nearsighted by a known amount and get the distances involved into a convenient range. You might try the test without the +1.50 glasses. If you have developed enough myopia, If your myopia is less then about -1.25 your arms probably are not long enough to do the test conveniently. Remember, Sir Isaacs equation that relates focal distance to lens power.

Have you read my piece on "How to Study for an Eye Exam"?

My only suggestion at this point is to not be too knowledgeable about optics and myopia unless you feel comfortable mentioning something about Optical Physics to your ECP. If you relate some of your symptoms, that will clue the ECP to be looking for myopia.

A couple of small tips.

1. If you have read "How to Study" don't ask to "fine Tune" the axis angle. I don't remember if the prescription you got included any Cylinder and Axis. That request would be too advanced for a first time glasses wearer to ask.

2. If your ECP uses the Red/Green test to check for slight over correction, try to remember the rule: If Red is clearer than Green you need more MINUS. Don't push that more then on "click".

I amy have some more tips later, but I don't think it is very likely that you will not get a prescription at this exam.

BTW, there is no such thing as Minor Surgery, if it is on you. Minor Surgery only happens on somebody else.

Check out the Zenni website for glasses frames. If you like the frames on the -2.25 glasses, you might want to select a similar frame for "your glasses" and a candidate frame from Zenni. That will give you more freedom to wear different glasses without comment such as you got some new glasses. People typically don't notice lens power changes, unless they are very significant.


Soundmanpt 19 Jul 2016, 07:42


Just checking to see if you have placed your order for your glasses yet?

CJB 18 Jul 2016, 23:02

Cactus Jack,

Thank you. I just had to have a couple of surgeries.

Yes, I have experienced all of them but the white boatd one, I always had Scott's glasses on during school.

Yes, I did it with +1.5 glasses.

1. Yes, very much.

2. Yes, I have to squint to make out stuff.

3. Yes, cannot even make out my clock actoss the room anymore.

4. Yes, that is exactly what it feels like, it is so weird and uncomfertable without them on.

5. They did not even realize they were his. They just asked when I got glasses, and I said I am borrowing them from a friend until I have my appointment and get my own glasses because they help me see. They bought it. Scott played along too.

Cactus Jack 18 Jul 2016, 22:15


Welcome back. I have been concerned that you might have been "busted". I hope the hospital stay was not too serious.

If I remember right, you did not have any problem getting a -1.00 prescription so it is likely, with the right symptoms, you will get a prescription and fundamentally, that is all you really want. You may recall that I mentioned some common symptoms. A -1.00 prescription means that you cannot see clearly beyond 1 meter. That means you probably can't:

See a menu board clearly.

Read Distant signs,

See the White Board very clearly unless you are close to it.

See clearly at night.

Have you actually experienced any of those symptoms without the -2.25 glasses?

Have I ever suggested the simple eye test using weak reading glasses? You can get a pretty good idea of your prescription with a book or newspaper, a tape measure and a known low plus reading glasses.

I would like to ask a few questions about the -2..25 glasses.

1. Are you comfortable wearing them pretty much full time?

2. Does you distance vision seem a bit blurry when you take them off?

3. Is your vision a bit blurry when you wake up in the morning before you put on the glasses?

4. When you are not wearing the -2.25 glasses do you feel like something is missing?

5. Did Scott's parents say anything about your wearing Scott's glasses?

I may have a few more suggestions about the exam, when you respond.


CJB 18 Jul 2016, 21:25

Cactus Jack,

Hey, sorry I have not been around, there has just been a lot going on. I was in the hospital for a while, and on vacation with Scott;s family after it was okayed by my doctors. I have to the best of my ability stuck to the plan. I wear Scott's -2.25 glasses whenever I can. I wore them all the time for the two and a half week vacation with his family, and whenever my parents are not around. Also, I was able to convince my parents that I need glasses, and my mom got my August appointment moved up to this Friday. Any advise? How should I act during the appointment? I am so nervous. What if the doctor sees through my plan??

I do feel like I have induced some more myopia.

Chino 15 Jul 2016, 16:19

Here are some more links that I couldn't fit into the previous post. Some of these are more of a reference as I started looking into different contact lens materials.

Chino 15 Jul 2016, 16:16

Hi everyone. It has been a while. I had meant to continue that experiment with the last filter lens, ARG. Then life happened and I never got around to it. I probably won't be able to until later this year.

Cactus Jack, I'd like to pick your brain. At this point, I've pretty much accepted what many people say on here, that once you're fully grown, the eyes have become about as myopic as they're going to get.

I've recently read some research on myopic creep in adults who wear contact lenses. While the myopic shift is greatest in young adults (20s), it still occurs even in older adults. From what I remember, the study included adults who were up to their 40s. Myopic shift was highest in adults who wore contact lenses with low Dk/t values. Low water content was also positively correlated with myopic shift rate, but that's not as useful today, since it seems like the only hard lenses around are the RGP ones. All we can work with at this point is the low Dk/t lenses.

Had you heard about this before, Cactus Jack? Has anyone on here observed this about other adult contact lens wearers? Is the myopic shift a constant thing throughout lens use, or is it just a one-time shift for new contact lens wearers?

The myopic shift is low, especially when compared to the colored LED experiments, but it's better than nothing. Does anyone on here wear soft contact lenses daily? If so, have you observed this myopic shift?

This could give me something else to try if the ARG lenses don't work.

Here are some links:

The post by amywithglasses about her aunt was interesting. Based on her age, I'm guessing that the hard contact lenses her aunt used were not RGP, so I wouldn't be able to reproduce that experiment.

This one is interesting, and may suggest a mechanism that is probably uniquely effective with contact lenses versus glasses - peripheral hyperopic refraction on the retina.

Michael 14 Jul 2016, 16:30

Soundmanpt-Thanks for the info. I didn't know that. This is the first time I ever ordered from Zenni and it seems like they are a very reputable company.

Soundmanpt 14 Jul 2016, 16:23


Zenni claims that from the time a glasses order is received the glasses are made and ready to ship withing 24 hours. The problem is the time it takes getting them through customs. I'm not sure if you know it or not but if Zenni sees that orders are being held up in customs they will remake the entire amount of orders that might be held up. So it could easily be several hundred orders held up that they replace at no charge and you as the customer get the benefit of getting a double order. Several years ago a good friend of mine who just happens to be the optical manager of a Sam's Club placed an order for glasses for herself after my constantly coming into her store and showing her samples of the glasses Zenni had. At the time I went in she was getting concerned because it was a few days past the 2 week time frame they claim. I was also concerned as well so i called her a couple days later to check to see if her glasses had ever arrived. She ordered 3 pairs f glasses and on one day she got one shipment and the next day she got the 2nd shipment. She was quite happy about that. She came out like a bandit because one of her friends that works in the store saw her wearing one of her new pairs of glasses and loved them. So she ended up selling her the extra pair. Her prescription is only -.75 in both eyes. She didn't say but I think her friend didn't really need glasses and just liked how cute they were. Anyway I never asked if she changed the lenses but I don't think she did.

Michael 14 Jul 2016, 15:05

Soundmanpt-When I ordered sunglasses for Chris I used PayPal and had no problem at all.My guess is any debit card should work as well so Nix should not have any problems. And glad to know that generally you get your glasses quicker than the 14 to 21 days they say. Chris asked me yesterday about the glasses. She seems anxious to get them which tells me she is having issues driving.I was not going to pay extra for expedited shipping. Since I am the one paying I was trying to keep the cost as low as possible. I ordered them on Monday and checking the status it shows as complete meaning the glasses have been made and now waiting for internal transfer to be checked off. I guess the next step is for the glasses to be shipped out.

Soundmanpt 14 Jul 2016, 09:36


I appreciate the fact that you're providing updates with your journey to induce myopia. I don't see any reason why your debit card won't work. That is all I ever use with ordering glasses from Zenni. Sorry to hear that international shipping is a bit longer than the 2 weeks I had told you. But for what its worth don't be surprised if your glasses don't arrive sooner than the 21 to 28 days. Over the past year or so every order I have placed has come in between 8 and 10 days which is considerably better than the 2 weeks they claim. But still just another reason to place your order as soon as possible since I know you're excited about getting your stronger glasses and getting started. If you measured your current glasses across the front of them and they are 140mm and they are comfortable on you and don't seem too big then yes 138mm is going to be fine because as you know 2mm is hardly anything at all. And of course until you get your new glasses continue wearing your current glasses full time. You've only been wearing your current glasses for about a month and their not very strong but they are clearly having an effect on your eyes. Things are much more blurry now without your glasses then it ever was before you started wearing your glasses. And as long as you enjoy reading keep your glasses on, dim the lights and hold your reading material as close as possible to your eyes. Hope your able to place your order soon.

Nix 14 Jul 2016, 09:10

I mean im gonna wear my current glasses full time hahaha srry for that. I didnt reread it

Nix  14 Jul 2016, 08:40


Yeah my current glasses are 140 mm so i think a 2mm off wont be too bad :). actuallu i dont have a credit card yet so I'm gonna try to pay using my debit card through paypal. i hope everything goes well. Sadly the shipping is 21 to 28 days long for international shippings. So imjust gonna update you when I get them :) for now im gonna wear my current glasses online and do a lot of close of work.

Soundmanpt 13 Jul 2016, 09:02


Yes getting 3 pairs at the same time is really the correct thing to do because not only do you save the cost of 2 shipments but you never know that when you're ready to order your 2nd or 3rd pair those glasses could even be out of stock. This way you are already so that once you feel like your eyes have completely adjusted to your first glasses you can simply switch to the 2nd and 3rd pairs when you feel your eyes are ready for the stronger glasses without anyone noticing any difference in your glasses except you of course. The glasses you're planning on ordering look very nice. They are simple which is even better since you really don't want to draw too much attention to your glasses anyway. I noticed that the ones you're ordering are 138mm wide is that pretty close to how wide your current glasses are? If you order your glasses like oyu say you're intending to within the next week or so i'm certain that you will be seeing perfect with your new glasses and without them you won't be able to see anything written on the board at school. Now if you were to leave your glasses off, which of course you don't want to do, after a short while your eyes would start trying to revert back to what your current vision is now, but things should still remain at least somewhat blurry. Your certain to be wearing the stronger of the 3 pairs of glasses your ordering in no time at all. You're almost guaranteed to get the results your hoping for because you're still at a good age for your eyesight to be changed naturally or with added help. In the short time you have been wearing your current glasses you can already see the results your cheating has had on your right eye. You're clearly a little more nearsighted in that eye than your left eye which you didn't cheat with.

When you get your glasses i'm sure your going to test all 3 pairs just to see how well you're able to see with them. Without pushing your eyes too hard if you find that the -2.25 -.50 165 / -2.25 -.50 25 glasses aren't too strong for you then you know you can return the weaker ones for half your money back. Are you going to skip getting your glasses with the AR coating since that is $5.00 more for each pair?

Anyway it seems like you're all set and ready to place your order. If you have any question about placing your order please ask.

Nix 13 Jul 2016, 03:14


Okay! I will order the prescription you suggested. The frame I chose is pretty cheap. It's just $6.95. But because of the shipping cost, I would like to order 3 glasses already.

So for the first glasses OD -1.25 - 0.50 ax 165, OS -1.25 - 0.50 ax 25

2nd glasses, I will just increase the sphere by -1 diopter and everything stays the same.

and then 3rd glasses, -1 diopter more than the second glasses and of course everything stays the same

I would like to know if you think I should order 3 glasses already or do I have to wait until my eyes get adjusted to -1.25 before I get a new one.

And yes, I took your advice on measuring my current glasses. The frame I picked is pretty similar to my current glasses except that my current glasses has designs on the temples.

And um yeah thanks :) I am very determined to be more nearsighted than I am now. I really hope I get the results I want. Thanks for all the help

Soundmanpt 12 Jul 2016, 07:10


You are correct young lady. Because you're wearing your real prescription for your left eye much of what you were seeing at a distance when you first got your glasses was with your left eye. But by wearing your glasses constantly like you have been you have slowly been using your right eye more now. The reason you're now noticing that without your glasses now even your left eye is a little bit blurry now compared to when you had your first glasses to correct your astigmatisms. But the difference now isn't sue to you now being very slightly nearsighted in that eye but rather because you're now wearing your glasses all time and blur is because of your astigmatism. By hardly ever wearing your first glasses your eyes never really got adjusted to the astigmatism correction. I understand why you didn't wear your first glasses very often because since your eyes never got adjusted to them you felt like you were able to see the same with or without your glasses. If you had wore them full time like you are currently your vision would have noticed that things would have been about as blurry in both your eyes as they are with your left eye now. The results of the test I had you do is exactly what I would have expected. Your young so that should allow your eyes to be changed rather easily. You clearly didn't seem to have any issue wearing your current glasses when you got them and really you made your own vision off somewhat by cheating and getting glasses with one lens stronger than the other. That i'm sure was throwing you off at first for sure. But based on your test you did and that you are completely comfortable wearing glasses and seeing perfect with them says a lot. One thing for sure is that you do seem very determined to induce enough myopia that your not going to be able to see very well without your glasses. You seem to understand that once your eyesight has been ruined there is no way to reverse what has been done and you will need either glasses or contacts for the rest of your life. Of course if you can afford it and your eyes aren't changing you can of course get lasik and return to perfect eyesight that way. In my post last post I did provide you with what I think you should order for your glasses now that you let it be known you did some cheating when you got your eyes examined. It's only very slightly weaker in your right eye because your right eye is probably still not fully adjusted to the -.75. It's possible that if you were to get your eyes examined tomorrow you might be at -.50 in your right eye. So by going with -1.25 so that is yet another -.75 additional to what your right lens is now. And since you really should balance your eyes to the same prescription since you were probably already really at -.25 in both eyes anyway your adding a full -1.00 to your left now and I think that is about right without pushing your eyes to hard. Like you pointed out you need to be able to see perfectly with your glasses by the time school starts.

I kind of had a feeling that the idea of wearing glasses didn't come up recently. So you have been wanting glasses for a very long time. Now that finally have glasses and wearing them full time you must be thrilled beyond words and and even more happy at the prospect of soon wearing even stronger glasses.

Glad to hear that you have selected the glasses you're planning on ordering. I hope you found glasses that are around $12.95 and not more expensive because I don't expect you to wearing them for very long before you will need to order if possible the exact same pair but with stronger lenses. By getting the exact same glasses no one will question why you got new glasses so soon. The less attention you draw to yourself, or your glasses, the better. Also if you were to get a completely different pair you know all your friends are going to be wanting to try them on and since they must wear glasses they might be very curious why your glasses seem to be getting stronger so fast. Did you take my advice about comparing the size by measuring your current glasses across the front and finding glasses that are very close to the same size? You know how nice and comfortable your current glasses feel to wear so you want whatever glasses you order to feel as comfortable as well. I look forward to seeing what your getting. Don't forget the sooner you place your order the sooner you will have your glasses.

It didn't take me awhile to see clearly with my glasses because my left eye has the real prescription. It took me two days or three I think? I didn't really notice because I got comfortable with my glasses pretty quickly. I wear them now right away when I open my eyes in the morning until I sleep. It was kinda hard to walk at first but I liked how things appeared closer to me. You are right, it was hard having my right eye having a slightly overcorrected lens.

I did the test you asked me to do and tried to read letters from a distance. My right eye is slightly blurrier than my left now. I guess my right eye has gotten used to the -0.75 lens. One thing I noticed though is that my right eye with glasses on sees better than my left with glasses on. Does this mean that -0.75 is now my right eye's real prescription and my left has slightly gotten worse? What prescription should I get now?

And yes, lol. Actually I have been wanting to wear glasses since 1st grade because my classmates started wearing them. I told my parents to get me an eye exam but they refused so. Until later when I could afford to get my eyes checked, I got my first pair, which happened last year. Because the glasses were just for astigmatism correction, I got frustrated that I would never be nearsighted and just accepted my fate. (It was actually around october 2015 when I got my first pair so I guess it wasn't a year ago, but few months ago hehe sorry) Then I noticed that the letters across my room were no longer readable from my bed so I got my eyes checked again, then I later found out that I got slightly nearsighted. Maybe being a college psychology student who does a lot of close work made my vision a bit worse? My old dream of being nearsighted sparked in me again. I searched and searched the internet on how to induce myopia until I found this forum and I am so happy I did :D YAY

And by the way, I've already picked a frame at zenni's and I am so excited. I am going to show it here once I place my order. :)

I would like to ask a question. I am from India and girls are so shy here. I got a friend she wore thick plus glasses , she doesn't like her glasses, don't want to talk about it, I have been persuading her since 2 months. Finally she told me she is wearing her glasses since childhood. But she never told me her prescription. Yesterday finally while joking on her glasses she told me she has+4 prescription. When I asked her can you see without glasses? She said yes I can, , I am little bit suspicious about it. Because lens are so thick and she wear them each and every time, ,, can anyone tell me she has+4 prescription can she see? Can she able to read without glasses? Is she really need them? If someone has experience or knowledge please answer me

Generally speaking it's usually pretty difficult to fool and optometrist because of the number of tests and retests that they tend to do. So if you're really pretty sure that you right eye really probably only needed the same -.25 as your left eye and you managed to get a -.75 lens for that your right eye you did good. So when your glasses came in and you went in to pick them and get them fitted didn't things look a little weird with your right lens being stronger than your left lens. How long did it take you before you were able to see pretty good with your glasses? Being out of balance like that is much more difficult for your eyes to adjust to then if they were both seeing through the same prescription. Did you do the test I mentioned to you in my last post? Now that you told me that you cheated on your eye exam before you take your glasses off and cover your left eye to test your vision, keep your glasses on and block your left eye and test your right eye to see how well you're able to see with your glasses. I'm guessing you now have perfect or even slightly better than perfect vision with your glasses on in your right eye. now do the same test without your glasses. Seeing with only your right eye things should be noticeably blurry now without your glasses in that eye. Your glasses in that eye are only -.50 stronger than you really need but even with that small amount of over correction it's having an effect on your eyesight. I'm glad to hear that you're comfortable wearing glasses. It's a big step going from part time wear or in your case hardly anytime wear, to wearing your glasses full time but you seem to be a very determined young lady with your desire to induce myopia. I am curious you got your first glasses just over a year ago due to astigmatisms, you got glasses but you hardly ever wore them so you don't sound like the kind of girl that always wanted to wear glasses but never needed them but wanted to induce myopia just is she could wear glasses. And even your last eye exam if you hadn't cheated your eyes didn't really change hardly at all from your first glasses which you seldom wore. So what has made you now decide that you want to make your eyes sight bad enough that you will need to wear glasses full time? Anyway now that you are already wearing some over correction for your right eye I suggest that we change the glasses your planning on ordering so your making both eyes the same. I suggest R -1.25 -.50 165 / L -1.25 -.50 25. That anther -.50 stronger than your currently wearing for your right eye and a full -1.00 stronger for your left eye. You shouldn't have any problem adjusting to this prescription and seeing perfect with them by the time school starts. Be sure to keep your current glasses for the next time you get your eyes examined. You may want to about next year this time jut to see what progress you have made. So you want to wear the glasses that was prescribed to you then. Don't be surprised that you will hardly be able to see anything wearing them by then. I don't think you will have to cheat next time you get your eyes examined. The eye chart should be quite blurry which is what you're wanting.

Nix 11 Jul 2016, 08:18


Thanks!! Actually, to be completely honest. I kinda lied during my eye test. When she was testing my right eye, I already memorized the line for 20/20, so when she put on a stronger lens on my right, I tricked her that I could see the smallest line from the -0.75 lens.. I think my right is just -0.25... I feel bad for it :(

And yes that's true. I've gotten so comfortable with my glasses that I miss them when I'm not wearing them. Sometimes I don't even realize that I'm wearing them haha! :D And yeah, I feel like my eyes are getting blurrier.. I am starting to read a lot now which I didn't really do back then. I am planning to buy my glasses this week or next week hahah! :D Picking out a new frame is pretty challenging for me cause I just want to make sure that the new frame will be pretty similar to my old frame orl suit my face lol im so pickyy

Hmm anyway good morning and have a nice day ahead :)

Soundmanpt 10 Jul 2016, 11:38


What Cactus jack was explaining to you is completely right. When people look at you wearing glasses they see you wearing glasses, they either like or don't like your frames of your glasses but they don't pay any attention to how thick or thin your lenses are. Now of course when your friends see you wearing glasses some of them are sure to want to try your glasses even more so if they wear glasses them self. You only really started wearing your glasses since you got your current ones. Your friends have probably had glasses a few years already, but when they got their first glasses they were likely not any stronger than your glasses are. So it makes sense that when they try your glasses on your glasses are much too weak for their eyes now. Trust me once you get your glasses from Zenni and wear them a few weeks and then you try on your current glasses they are going to be too weak for your eyes as well. You may need to be a little careful when you get your glasses from Zenni with anyone that has tried on your current glasses. they are much more likely to notice that your Zenni glasses are somewhat stronger. I'm not sure when school starts for you but from the time you place your glasses order until they arrive should be about 2 weeks. But I honestly don't expect any problem with your eyes adjusting rather quickly to your glasses when you get them. Now that you're wearing your glasses full time how do you feel about wearing glasses all the time now? Are you beginning to feel comfortable wearing glasses? Your glasses should become so comfortable that you hardly realize that you're even wearing them and you miss them if you don't have them on. You're getting a pretty good training about what things look like when your nearsighted. Things are a little blurry now when you take off your glasses and when you're watching TV and take off your glasses you probably are still able to see it pretty well because your brain will turn off your right eye and your left eye is only -.25 for distance. Next time you're watching TV try taking your glasses off and hold your hand over your left eye. Now how well can you see the TV? Right now even though you have had your glasses for about a month your eyes are still probably not fully adjusted to them yet. So when you wake up in the morning your eyesight probably seems pretty good still without your glasses, but after you wear your glasses all day by the that night it makes sense that when you take your glasses off things are going to look much more "fuzzy" to you. Your morning eyesight without your glasses should slowly become more "fuzzy" as well as your eyes fully adjust. When do you plan on placing your order? Be sure to show which glasses you decide on. Have a great day!

Well the majority of the people I live in are nearsighted, very nearsighted actually they have thick lenses. They don't say anything about my glasses but my friends and I sometimes try on each others' glasses and they ask me why I even have glasses with low prescription. I am planning to buy glasses before my classes start so I can get used to the glasses and be able read from a distance already. And thanks, that helped me feel better :)


Oh thank you! I didn't know that zenni was international haha! I'm going to get my glasses from zenni then :) And yes, it does make a difference now. I can already notice the blurriness now when I take off my glasses when watching tv. I like how things get clear when I wear them back on. Things appear fuzzier at night though. And oh, even walking feels weird without my glasses now. My new glasses make me feel smaller and I've got used to that so when I take them off, the geometry feels different. And thanks I'll look at the offers. :)

Soundmanpt 09 Jul 2016, 11:26


Zenni is international so they ship everywhere. If you have mail box or a place where you get mail they will get your glasses to you. Now it's totally up to you where you go to get your glasses from but I am only recommending Zenni because they have a very good track record and I have used them over the past 11 years and they have always done a great job and was only late once and because they were help up in customs they simply replaced my entire order at no charge to me. So everyone ended up with 2 pairs of glasses so they were fine with them being a couple days late. One thing that Zenni offers which you should like is that thye offer 2 options of free lenses one that is 1.50 and one that is 1.57 the 1.50 lens is a thicker lens and is really made for people with very weak prescriptions that get rimless or semi-rimless glasses so the lens is thick enough to drill without breaking. But they will fit it in any of their frames.

I am glad to hear that you're now wearing your glasses full time. that really helps for several reasons. First of all now you're pretty well used to wearing glasses and that helps since wearing your glasses when you get them is a very important part of inducing myopia. Also since you now nearsighted that is like taking the first step in prescriptions. Your glasses aren't very strong but now at the end of the day i'm sure you have noticed that when you take your glasses off things are at least a little blurry something you probably hardly noticed with your first glasses.

Cactus Jack 09 Jul 2016, 11:09


I get very impatient with people who think they have a right to pass judgement on another person’s visual needs. The idea that you need to have a certain reduction in Visual Acuity to be “authorized” to have vision correction is, in a word, STUPID. It is like saying that a person does not need to wear shoes, because in MY opinion the rocks are not sharp enough or the pavement not hot enough to hurt YOUR feet.

In practical terms, a person who is mildly Myopic and needs only -0.25 correction, cannot clearly see anything beyond 4 meters or 13 feet. That means that they cannot see leaves on trees or possibly birds in the air, stars in the sky, or read small signs, beyond that distance. They might not be able to recognize a friend, across a wide street. -0.25 Astigmatism (cylinder) correction, makes it even worse because it affects vision at all distances.

A person who needs -0.50 Sphere Correction moves the point where thing get fuzzy to 2 meters or about 6.5 feet.

Both -0.25 and -0.50 don’t look like much of a correction to others, but they can make a big difference to the person who needs them, IF their world and interests are beyond 4 meters or 2 meters, respectively.

Low MINUS prescriptions may not make much difference inside (except in classrooms and the cinema), but they can make an important difference outside. Prescriptions with Astigmatism correction make an important difference both inside and outside.


Nix 09 Jul 2016, 09:43


Exactly what I'm gonna do, haha! Actually I'm not so sure if Zenni Optical does shipping in the Philippines too.. So I looked for other glasses online. And thanks, :) Im so going to do all that you guys have suggested. I am very determined to be more myopic.

I didn't wear my old glasses full time because the lenses looked like they had no pwer at all and thought that I looked ridiculous wearing them full time so i just wore them occasionally. But i am now wearing my new glasses full time.

Soundmanpt 08 Jul 2016, 10:54


Nice to hear that you won't have any worries about getting caught by your parents. So I assume you're just going to say you just wanted another pair of glasses and found that you could order them on line so inexpensively. Of your new glasses are sure to look different frame wise than what you have now. You didn't say if you have had a chance to look at any glasses yet but one tip so the glasses you get fit your face well is to find a ruler that has millimeters on it and measure your new glasses or your first ones, whichever ones fit you the best, across the face from outside left to outside right. That is called the "overall width" and when your picking out the glasses you want and click on the picture it will provide you with all the various measurements of them temples and the bridge and even the height of the lenses, but the one you need to be interested in is the "overall width". you want that to be close to what your glasses are now. If you need any help in placing your order come in here and ask. I check this site several times a day. Don't forget to find where you can get the optional AR coating which is really nice to have since you're going to be wearing your glasses full time. If you do the things suggested by Cactus Jack, Likelenses and myself, I think there is very little doubt that your going to induce true myopia. Your at a good age where your eyes are more easily changed and the fact that your eyes are already starting to become nearsighted on their own without you even trying is a clear indication that even without doing anything by next year your going to be more nearsighted than you are now. Doing what you're doing now is only pushing things a little faster. To get your eyes to be around -2.50 which is what you're hoping for, your going to have to get to where Cactus Jack suggested glasses that are -3.75 -.50 165 / -3.25 -.50 25. That should put your actual eyesight at about -2.25 to maybe -3.00. Once you pick out the glasses you're ordering please send a picture of them or the number of them. And yes of course were going to be interested in hearing your progress once you get your glasses. By the way since you recently got your new glasses have you been wearing them very much? If not you probably should start wearing them full time so that when you get your Zenni glasses your eyes will already be adjusted to the prescription you already have.

Nix  08 Jul 2016, 10:05


Aww! Thank you! Happy birthday to you too! I'm going to get glasses now. a little bit excited :D I found a way ordering one without getting caught. My parents are always busy anyway and they don't pay much attention to what i order online.


Thank you for all the tips!! I am going to make sure I do all these!! And yep no cheating!! Promise you that

Cactus Jack

Thank you for taking time to explain it all to me! I am going to get glasses as you advised and I hope i hope it works for me. I hope I get moooreee myopic

I am going to update you guys of my progress. :) I hope I get "worse" true myopia. A big thanks

Likelenses 07 Jul 2016, 21:25


There are a few things that you can do to help induce more myopia.

Always wear the glasses for any close work,and bring the reading material as close to your eyes as you can tolerate.

For books always closer than twelve inches,and desk top screens closer than twenty inches.

When viewing distant things such as TV ,wall menus, sporting events,try to get in the habit of squinting,with the glasses on of course.

Basically you want to establish the habits that nearsighted people have.

Also very important to put the glasses on as soon as you open your eyes in the morning,and leave them on until you go to bed at night.Constant wear,no on,and off cheating!

Soundmanpt 07 Jul 2016, 09:55


First of all happy belated 18th birthday. I just had my birthday yesterday only difference is that I was celebrating or complaining about being 68. So you just got your 2nd pair of glasses last month so that means your not due for another eye exam for a year so you can't use that for a reason to be getting new glasses. I'm mot at all surprised that your eyes changed some since you got your first glasses. Actually i'm surprised they even prescribed you glasses when you only had what must have been the very weakest of astigmatism correction. So I don't know how much you wore those glasses but now that you're a little bit nearsighted and your astigmatisms increased do you wear your glasses more often now? When you're ready to order glasses have you figured out a good way to do it without getting caught? Needless to say this is always a big problem when you're still living at home.

Nix 07 Jul 2016, 09:10


Actually I just turned 18, few weeks ago.. I got my glasses last month. This isn't my first pair... I got my first pair last year.. The lenses were for astigmatism only. But now im nearsighted and my astigmatism got worse slightly. And thanks! I'll try getting glasses soon!!

Soundmanpt 07 Jul 2016, 08:49


First of all the advice you have gotten from "Cactus Jack" is the same as I would suggest to you as well. You currently have glasses which based on your prescription I would have to assume they are your first glasses? How long have you had your glasses? I'm assuming most likely less than a year, but this at least an indication that your eyesight is starting to change naturally? You haven't reached your 18th birthday yet so it is almost certain that your eyesight will continue to change over the next few years on their own. Now if you want to speed things up so your glasses are much more necessary even faster I don't think it will be a problem for you. The progression that "Cactus Jack" has suggested to you should work well for you. By starting with glasses that are only -1.00 stronger than your current glasses you will quickly find that your eyes will love the over correction and your eyes will adjust to them very quickly. Once they feel completely comfortable to to you is when you would want to switch to the glasses with the -2.75 -.50 165 / -2.25 -.50 25 prescription. So as long as you pick out a full plastic frame for glasses no one will notice any change in your lens thickness from your current glasses. Since I started this post I see that you have commented again about your situation. I was pretty sure you were most likely still living at home. This of course does cause some issues for you. Of course inducing myopia by wearing contacts can be done but I can you it is getting harder and harder to find any place to order prescription contacts on line. Plus trying to hind everything you need for cleaning contacts and such I am sure you would get caught either putting them on or taking them off or just mom seeing the solutions around in the bathroom. Also the way you have to buy contacts they would be considerably more expensive than buying several pairs of glasses. I do get why you're asking about contacts because that way you would still be wearing your current glasses while you were inducing. Also even if you found a place to order contacts from you really need a real contact fitting so they would be comfortable to wear. Just curious as to when you got your current glasses. I ask that thinking maybe it's getting close to time for you to get an eye exam. You are going to need a reason why you're wearing different glasses. Now one thing you could say is that one of your friends, that they don't know, is planning on ordering her glasses on line and that you saw a pair on the website that you really like and she is letting you order glasses with hers so you only have to pay one shipping cost. Then you just need to find some one that you can give them cash money if they will sue their credit card to place your order and have the glasses sent to their house. If go into ( you will find more than 800 pairs of womens glasses fro under $13.00 and even by adding on AR coating (anti-reflective) which is additional $5.00 the glasses would only be $18.00 each. If you get 3the same 3 pairs but with the various prescriptions like Cactus Jack suggested that would still only be $54.00 which isn't bad at all. One really nice thing is that you have everything you need so you can order your glasses.

Nix 07 Jul 2016, 07:55

Cactus Jack

Thank you! Yes I have been reading the old posts and I am getting more ideas. I don't mind getting new glasses if that's the best way to induce myopia.

It would be best if I could make myopia permanent...

And yes I do live with my parents still, thanks for warning me about that..

I would also like to ask if it's possible to induce myopia by getting contacts instead plus wearing my current glasses on and increase the prescription of my contacts as I get accustomed to them?? And are there any diet that can help enlarge my eyeballs?

Thank you so much and I can't wait to wear thicker lenses. :)

Cactus Jack 07 Jul 2016, 06:51


Thank you for advising your gender. More about how that affects Myopia later.

As I mentioned previously, there are two types of Myopia. True or Axial Myopia and False or Pseudo Myopia. Axial Myopia is caused by excessive eyeball growth and with rare exception, it happens slowly and is considered permanent because the eyeball can't "un-grow" or shrink very much. Pseudo Myopia is caused by inability of the Ciliary Muscles and Crystalline Lenses to fully relax for distance after focusing close for an extended period. Pseudo Myopia is considered temporary, but that is a relative term. "Temporary" can range from fractions of a second to months or years depending on a number of factors. Initially, at your age, you will probably be able to create some Pseudo Myopia in a few seconds when you put on your over-corrected glasses and it will mostly disappear in a few seconds, when you take them off, but over time that may change as your Ciliary Muscles become accustomed to maintaining the extra PLUS in your Crystalline Lenses and will have difficulty relaxing. As you get older, Presbyopia will gradually cause the transparent protein that makes up your Crystalline Lenses to become stiffer and changes in the PLUS power of the Crystalline Lenses will occur much more slowly. If you get lucky, you many also get some eyeball growth and you will develop some Axial Myopia.

A few tips. Periodically, you may need to get an Eye Exam to measure your progress and perhaps adjust the prescription in your glasses. Typically, when you are trying to Induce Myopia, you can only visit an Optometrist or other Eye Care Professional (ECP) once. The reason is that most ECPs are very interested in your visual history and if they have prescribed glasses in the past, will not understand the cause of big changes in your prescription and they will ask questions you don't want to answer. They will understand small increases, but absolutely NOT understand decreases, which can occur if the most of your Myopia is Pseudo Myopia, because of your age.

Also, depending on where you live (IOW with your parents), you may not want to use your real name, address, or a credit card to pay for an Exam. Many ECPs will send mail with reminders etc. which can cause family questions.

That is enough for you to think about for now.

There is another Myopic factor for women. Sometimes, if a woman is genetically disposed for myopia, becoming pregnant will cause Myopia to increase dramatically. The reason for this seems to be that as the fetus develops, all kinds of hormones are circulating in the mother's blood stream, including the mysterious Eyeball Growth Hormone. That seems to stimulate growth of the mother's eyeballs and a permanent increase in myopia.

Please let me know what you decide to do and if you have more questions. You might look back on this thread for the posts by CJB. His posts suddenly stopped without explanation. I have my suspicions, but no certainty about the reasons.


Nix 06 Jul 2016, 17:52

Hello, I am Female :)

Yeah, i now understand how the optics works.. Thanks for chopping and simplifying it all.. I dont mind going past -2.50.. I'd like to achieve at least that..

Cactus Jack 06 Jul 2016, 15:48

Nix,It sounds like you have a very considerable reading and close work requirement ahead of you. If you are genetically disposed to myopia, I suspect you will wind up with more than the -2.50 you mentioned.

Let me explain a bit about Myopia and how the optics of your eyes work. I suspect you do not have a strong math or science background and that is OK. I just wanted to know so I can use understandable language. The principles and math involved are pretty easy. It is just a practical application of the Principles of Optics discovered and codified by Sir Isaac Newton, of Gravity fame, around 1700. The more you understand about vision and optics, the more effective your efforts will be.

The most fundamental formula or equation of optics is:

Focal Distance of a Lens = 1 meter (100 cm, 1000 mm, or 39.37 inches) / Lens Power in Diopters.

That equation can be re-arranged to:

Lens Power in Diopters = 1 meter (etc.) / Focal Distance (of course the units of distance must match)

Vision actually occurs in the brain. The eye is simply a amazing biological camera. The typical Human Eye is about 1 inch or 25 mm in diameter. There are 4 PLUS lenses in the eye's lens system. From front to back they are the Cornea, Aqueous Humor, Crystalline Lens, and Vitreous Humor. The lenses are recessed into the eyeball so that the typical distance from the back of the Crystalline Lens to the Retina is about 17 mm. If you use the formula above and divide 1000 mm / 17 mm you get about +59 total diopters in the eye's lens system. 3 of the 4 lenses are fixed power. The Crystalline lens is variable power. The Crystalline Lens is surrounded by some very tiny Ciliary Muscles that have the ability to squeeze the Crystalline Lens to increase its PLUS power. For their size, the Ciliary Muscles are the strongest muscles in the body. The Ciliary Muscles and the Crystalline Lens are what enable you to change your eye's focus. For Distance, the Crystalline lens needs to be at minimum PLUS power. For focusing closer than about 20 feet or 6 meters, your Ciliary Muscles need to squeeze the Crystalline Lens and increase its PLUS power enough to focus the close images on your Retina. How much depends on the distance. If you use the formula above, you will find that to focus at typical reading distance of 16 inches or 40 cm, you need an additional +2.50. That formula and number will come in handy when we talk about Inducing Myopia. It can vary some, but in the typical eye, the Cornea has about +40 diopters and the relaxed Crystalline Lens is about +15.

Both Axial or True Myopia and Hyperopia are caused by a mismatch between the total PLUS power of the eye's lens system and the distance from the Crystalline Lens to the Retina. The reason I emphasized Axial or True Myopia is that there are actually two types of Myopia. The other one is Pseudo or False Myopia, which is caused by the Ciliary Muscles and Crystalline Lenses. They have identical effects and are additive (both can be present in one eye). Both are corrected by MINUS lenses in glasses or contacts.

Most Axial Myopia is caused by the eyeball having grown a bit more than it really should have or the eye’s lens system has too much PLUS for the distance to the Retina. The result is that rays of light from distant objects are focusing in front of the Retina and a MINUS lens is required to move the focus of the distant image back to the Retina. The actual distances involved can be very small, about 0.3 mm per diopter of correction. This is one of those instances where a little bit goes a long way.

We do not know exactly what causes the eyeball to grow more than it needs to, but there are theories that out of focus images on the Retina cause the production of a specific Eyeball Growth Hormone (EGH)which causes the eyeball to grow, IF your genes permit it. It is further theorized that the focusing effort by the Ciliary Muscles and Crystalline Lens causes the production of EGH which in turn causes eyeball growth. That is the primary principle we will use to attempt to Induce Myopia. We need to tell you how to increase and maintain your focusing effort and hopefully cause the production of EGH. If you are successful, your eyeballs will grow a bit and you will become permanently more Myopic. To do that you need to wear more MINUS than you actually need and cause your Ciliary Muscles to squeeze your Crystalline Lenses and increase their PLUS power to compensate for over correction in your glasses.

There is a great temptation to start of with some pretty significant MINUS over correction in your glasses. Many of us thing that that is not as productive as starting with a small over correction that you can comfortably wear full time (every waking hour) and then make small increases as often as you can as your Ciliary Muscles get stronger. Think of it like lifting weights. You start with relatively light weights and gradually increase the weight and repetitions you do. If you wear your glasses full time, your Ciliary Muscles will get plenty of repetitions.

I would like to suggest starting with -1.00 over correction. At your age, you should be able to become accustomed to full time wear very easily, with only minor initial discomfort when you read. Here is the prescription is suggest:

OD -1.75 - 0.50 ax 165

OS -1.25 - 0.50 ax 25

PD = 62

Notice that I increased the Sphere by the same amount in both eyes, but made absolutely no changes to the Cylinder and Axis correction for Astigmatism.

If you can, I would suggest also ordering:

OD -2.75 - 0.50 ax 165

OS -2.25 - 0.50 ax 25

PD = 62

With identical frames as close as possible to your existing frames.

When you get comfortable with those, you may want to consider:

OD -3.75 - 0.50 ax 165

OS -3.25 - 0.50 ax 25

PD = 62

I suspect you will find that you can go to the -2.00 over glasses within a few weeks and be comfortable with them in less than a month after that. The key is wearing the glasses full time for all your activities, whenever you are awake. If you want to settle out at around -2.50, you will need to go over that level for a while before you go back

I have a several more tips, but that is enough for now. Please let me know if this makes sense and you understand the principles. I also have a few more questions.

May I also ask what subjects you like in school and your future education plans?


Cactus Jack 06 Jul 2016, 11:15


You should be able to easily wear glasses with more minus. That is the first step. If you can supply your complete prescription, we can suggest the prescription you should order.

As a minimum, you will need the prescription and your Pupillary Distance (PD). Many prescriptions do not list PD because measuring that is usually the job of the Dispensing Optician and they don't like providing it because they want you to order any glasses thru them. It is really easy to measure with a ruler calibrated in mm and a bathroom mirror. We can help you with that.

You will probably need to order glasses online and will need a credit card and possibly a confidential mailing address.

One of the most important things to understand about getting glasses with an increased prescription is that most people do not notice the lenses in glasses, unless there is a HUGE change in the prescription. They DO notice frame style changes. When you order new glasses that you don't want others to notice, you need to maintain the same frame style. We can make some suggestions about that also.

Many members order glasses from Zenni Optical. You might check out their web site and explore their offerings. They offer high quality single vision glasses for as low as US$6.95 plus shipping. The frame and options control the cost.

H. Thank you for responding. I just turned 18.. Well not my parents but i do have relatives who are nearsighted from both sides of the family and my siblings are also nearsighted.. I live in the philippines

Cactus Jack 06 Jul 2016, 10:38


The biggest factors in Inducing Myopia is your age and genetic makeup.

What is your age?

Are any of your close blood relatives nearsighted (Myopic)?

It would also be helpful to know where you live (country) because that may affect your ability to order glasses without an "official" prescription.


Nix 06 Jul 2016, 10:09

Hello! I got my glasses recently. I have -0.25 on my left eye and -0.75 on my right eye! I have been wanting to wear glasses and have been fascinated by thick lenses.. I'd like to reach at least -2.50on both eyes... Please help me :( I wanna induce my nearsightedness in the shortest period amount of time

Soundmanpt 07 Jun 2016, 16:15


Here in the USA it has gotten much harder to buy contact lenses that don't ask for your doctors name and phone number so they can verify the patient's prescription. It didn't use to be that way. Several years ago i gave a friend the name of a place that she could get her contact lenses on line for less than she was paying locally. She did in fact have a real prescription so of course when entered all her information and she got her contacts a few days later. She yold me later that about 6 or 67 weeks after she got her contacts they were calling her for information to contact her doctor. She said she just laughed about it and never bothered replying to them.

Maxim 07 Jun 2016, 12:42

To Soundmanpt: I completely agree, there might be problems. They know from your invisible computer adress, in which country the approaching computer (= your computer) is situated. And then, to avoid conflicts with national legislation, they might ask questions insome countries to fulfill such requirements. In our country, there are not such questions, but here you can buy contact lenses in super markets and drug stores, just from the shelf like a jar of instant coffee, no limitations. So they can do equally with net sales.

Soundmanpt 07 Jun 2016, 08:44


Your very welcome and one can only hope that you get the result you want. As long as your tenacious about keeping your glasses on from the time you wake up until you go to bed I think you stand a very good chance of inducing myopia. Being in pre-law you almost certainly are doing loads of reading and studying which that alone should be taking a toll on your eyes and now wearing your glasses should push that even more. At the time of your first post on March 28th you said that you had already been wearing your glasses for about a week so you should be heading into your 3rd week. By now you should be over the newness of wearing glasses and you should be feeling very comfortable wearing them. Just curious, you got your glasses from a friend that wears glasses how or what did you say to her to get her to give you a pair of her previous glasses? Does she think you just wanted her glasses because you like your looks wearing glasses or did you tell her that you want to make yourself nearsighted? Did she give you any advice about wearing glasses and is she a good enough friend to keep your secret about what your doing? It is not at all unusual for a girl to like how she looks wearing her friends glasses and get those glasses when the friend gets new glasses. Anyway please do keep us updated every couple weeks as to what progress your making.

Ricky 07 Jun 2016, 08:24

Hi this is Ricky..i am 36 years of age. Of late i have begun to notice that if i hold things close to my eyes its difficult to read. Since i like glasses i got my self a pair of progressive glasses with strength of L and R eye +1.0 with a add of +1.5. I have been wearing these glasses for 4-5 hours in a day and i can see very clearly with them. My question is how soon will i be completely dependent on the glasses?

coffeelover 07 Jun 2016, 00:02

@Cactus Jack, Soundmanpt, Likelenses

Thank you all for your help. Been wearing the glasses as much as i can. I will update you guys in a few wks time re my progress

Soundmanpt 05 Jun 2016, 17:58


I tried to get into that site and did get in but once I got to my date of birth I had trouble entering it so I couldn't go any further. I think that at some point because the brands are all well known they will ask for a doctor's bane to verify. I could be wrong though. If nothing else if it doesn't ask for a doctors name it could be a great site for anyone doing GOC. I agree with you though that "Closet Geek" is probably better off just getting glasses to induce with. She is already ahead of things since she already wears glasses full time anyway which is a good start when she is ready to start.

Maxim 05 Jun 2016, 13:25

My advice for CLs - cheap, reliable supplier:

If there are problems, try a Google search just with 'Dailysoft'.

There should be no problem - CLs with "sphere" values only, the astigmatism (cyl values) in the glasses.

But, however: a glasses-only solution is better, CLs are somewhat complicated, another item to hide, and sometimes (just now in summer) not easy for the eyes.

Good luck!

Soundmanpt 05 Jun 2016, 08:58


What your suggesting would work but I doubt that she has ever wore contacts since her actual prescription is for astigmatisms and she would need toric lenses for that. So she has likely only wore glasses for that. Also these days getting contacts even with just a SPH correction isn't that easy anymore. Not sure how well contacts would even stay on her eyes considering her CYL numbers, otherwise not a bad idea. I think it is going to be much easier for her to get glasses rather than contacts.

Specs4Me 05 Jun 2016, 08:17

Sorry for the double post, not sure how I managed that.

Specs4Me 05 Jun 2016, 08:15

Closet Geek,

Another thought is to get a pair of glasses with some sphere correction and then were contacts under your glasses. You could get glasses with -1.00 as suggested, then order a box of -1.00 and a box of -2.00 contacts which you could then wear under your glasses. Wear the -1.00 glasses for a couple of months and then wear the -1.00 contacts under your glasses for a couple of months which would give you the effect of -2.00 glasses. You would then wear the -2.00 contacts under your glasses giving you -3.00 of correction. After that you could order -4.00 glasses and go through the exercise again. This way you would not be changing glasses every couple of months but could get new glasses with an increase after a few months and lament to those who might comment about how your eyes are getting bad really fast....

When I saw your age as being 18 I was pretty sure you were likely still living at home with your parents or parent. And that like you say would be a problem if you were planning on ordering 2 identical pairs but with the 2 different prescriptions. You seem to agree that getting 2 pairs is the best way to go when and if you decide to try it. And that is for you to decide of course. Since your planning on moving out in a couple months you can wait until then and not have any problem at all at that point with getting more than one pair. And during that time if you decide you don't want to wait until you move out you can always just get the one new pair in the weaker prescription to start with and wear them until you get relocated then order the same pair with the stronger lenses. Most likely in that short of time they should still be available but even if they weren't and you had to order a complete different pair that still shouldn't be much of a problem since your a young girl and since you already wear glasses full time it is understandable that you might want to change to new glasses quite often. I'm sure you have probably told most of your friends about how inexpensive glasses are at Zenni. So if or when you decide to induce some myopia I don't think you will have any problem at all since your at a good age and your already wearing glasses full time so you already very used to wearing glasses which really helps.

Closet Geek 04 Jun 2016, 23:49

Thanks everyone for your replies!

I am a girl :) Don't worry about it though..."Closet Geek" IS a pretty gender neutral username.

Cactus Jack, that sounds like a good plan...I will probably go with that when/if I try to do this. My current glasses are actually from Zenni, so I know not to worry about the cost or getting multiple pairs. I live with family right now, so I'm kind of at a loss for a place to ship them, but I'm moving out in just a couple months so I could start then.

Soundmanpt, thanks for the input...I am already wearing glasses full time, so that shouldn't be an issue.

Maxim/Soundmanpt, I would agree that starting with the -1 would be better. My job is in retail, so not at a desk, but I do have school so I do some close work.

Cactus Jack 04 Jun 2016, 05:47


Maybe we can, but there are many things that can affect your ability to become more myopic. We need more information to even start.

1. What is your age?

2. What is your complete prescription?

3. Where do you live (country)?


shortsightlover 04 Jun 2016, 01:09

can anybody suggest an idea to induce myopia?i have only cylindrical power of -1.5 i my eyes.

I want to induce shortsight. wht can i do?

Soundmanpt 02 Jun 2016, 11:59


First of all not even sure if "Closet Geek" is a male or female? You never know it could be a cute little female geek but either way being 18 there shouldn't be any great rush and you even admitted that your eyes ached for several days after you had your glasses on for several hours. So if "Closet Geek" happens to have job or doing other close work that would be harder if the glasses feel overly strong. It is more important that they are able to wear their glasses all day long and if the glasses are too uncomfortable they are much more likely to take them off and too much. Starting with -1.00 glasses is a good start to inducing myopia. At the end of the day when "Closet Geek" takes their glasses off i'm sure he or she will quickly notice how blurry everything is. After wearing the -1.00 glasses for a month or so then switching to -2.00 glasses will not be so hard on the eyes. The glasses are cheap enough that if this person is serious about wanting to induce myopia the price of the glasses should be a problem.

Maxim 02 Jun 2016, 10:53

I would think, he could try to jump right away to a -2.00 prescription.

I did that, when I was 22.

I had got a Right eye -5.00 sph / Left eye -.200 sph glasses from a railways' 'Lost and found' office. These glasses I had been wearing for a week or so. I was unable to cope with the -5.00 lens for reading however, and so I took this lens out of the frame and asked for a repair (I pretended it was broken - so I avoided an eye test being made). I remember some aching the first two or three days after 3 or 4 hours of wearing them, then I wore them constantly.

At the eye test I was taking after 6 months, I had reached R-1.25/-0.75cyl 70 deg // L -1.25/-0.50 A 140 deg.

But this was turned out to be the maximum of myopia I ever reached. Inducing myopia was impossible for me.

At less than thirty years of age I was prescribed Right eye + 2.50/-1.00 65 deg// Left eye +2.00/-0.50 135 deg for Hyperopia now, and this always increased. I could not go without the glasses (not wearing plus lenses would be the same as wearing minus lenses), that was too much strain.

Everything "Cactus Jack" has advised you is what I would also suggest to you. But I just want to add how important it is that once you get your glasses and test them out to make sure your eyes don't have any problem adjusting to them which I don't think they will, you want to then make a point that you put your glasses on as soon as you wake and open your eyes each day and keep them on the full day until your about to close your eyes for bed at night. Constant wear is very critical with inducing myopia. Your young enough that you shouldn't have much of a problem inducing myopia. Based on your first comment it seems you have glasses and your astigmatisms are enough that you very likely are already wearing glasses full time? I too highly recommend that you get your glasses from Zenni ( and like "Cactus Jack" is suggesting order 2 pairs at in the exact same frame that way when you go from the -1.00 glasses to the -2.00 glasses there won't be any questions asked by your friends and family. Also make sure you include your actual CYL and axis information for you new glasses.

Cactus Jack 02 Jun 2016, 02:35

Closet Geek,

It should be pretty easy to do. You already wear glasses and if you keep similar frames, you can gradually increase your Sphere correction. Have you ordered glasses from an online retailer such as Zenni Optical?

I would suggest starting with a prescription like this.

OD: Sphere -1.00, Cyl -1.00 x Axis 120

OS: Sphere -1.00, Cyl -1.25 x Axis 43

When those get comfortable in a month or two, go to

OD: Sphere -2.00, Cyl -1.00 x Axis 120

OS: Sphere -2.00, Cyl -1.25 x Axis 43

Note that I did not change the Cylinder or Axis.

All you need is your PD, we can help you measure it if you don't know it, a credit card, and a place to ship the the glasses. If you can find some $6.95 frames you like, you can probably order the glasses pretty inexpensively. Even with shipping and the low cost A/R coating, you may be talking less than $17.00 If you order both pair at the same time, there will only be one shipping charge,

Please ask if you have more questions.


Closet Geek 02 Jun 2016, 01:29

I just realized I only answered one question. Oops!

I'm 18, from USA. No sphere correction at all, just the cyl I described.

Closet Geek 31 May 2016, 21:26

I would like stronger glasses, preferably minus lenses. I only have astigmatism correction now. Who can give me a step-by-step plan for inducing myopia?

Soundmanpt 29 May 2016, 21:30


That was very smart of you to first start complaining about having blurred vision even before you started wearing the glasses in public. I'm sure when you got the glasses from your friend you didn't wear the glasses out in public until you were quite sure that your eyes could see well enough wearing glasses. That usually does mean less questions will be asked because those around you probably thought you would soon be getting glasses. But now as you know your pretty committed to wearing glasses from now on or you might have to answer why your not wearing your glasses anymore. Not at all surprising that you had a bit of a problem at first with seeing things close such as reading from a book. But good that your eyes rather quickly got comfortable with reading with them. Even more important since your no doubt doing a quite a bit of studying and reading if your a pre-law student. Actually the more reading you do the better since that should help you with trying to induce myopia. Whenever possible dim the lights when your reading or studying. As far your question about how many months it may take for you to induce -1.00 myopia there is no way to predict how long it will take for any permanent change in your eyesight. A lot depends on how strict you are about wearing your glasses full time. The things yo want to watch for is things like how long it takes for your eyes to recover after wearing your glasses all day. If it now takes about 20 minutes, you would like to see it start to take longer and at some point for your eyes not to fully recover back to normal but instead remain slightly blurry without your glasses. If you constantly wear your glasses without fail and after 3 months you don't see any difference in your vision then it may not be possible for you to induce any myopia. But it certainly can't hurt to try because there is a good chance it will work. So how does it feel to be wearing glasses? Does your friends glasses fit you nicely? You do know that if they don't fit right or hurt behind your ears or on your nose you scan go to any optical shop and ask them to adjust them for you. They shouldn't charge you anything to do that and it is important that your glasses are comfortable to wear. Since your wearing your glasses full time you don't really need a case for them but when you take them off at bedtime be sure not to put them with the lenses down. Also when you need to clean them only use a soft cloth to clean them. At some point once you start to see that the glasses are starting to have a lasting effect on your eyes you will need to get stronger glasses if you want to get to around -1.50. This may seem wrong but to get to -1.50 your probably going to need to wear glasses with about -3.50 or stronger lenses. Your eyes are never going to get to where they are using the full prescription of the glasses your wearing. I see that you live in Manila, is mail service bad their? Zenni uses the mail service to deliver their glasses. So as long as you get mail getting glasses on line shouldn't be a problem. However if there is no mail then you do have a problem unless the friend that gave you the glasses happens to have some of her previous glasses that might be stronger than the ones your now wearing. Please feel free to ask any questions you still may have.

Likelenses 29 May 2016, 20:12


There are two other things that you should do while wearing the glasses. 1. Hold your reading material as close to your eyes as you can tolerate,and also get close to any computer screens.2. When viewing distant objects while wearing the glasses,get in the habit of squinting

coffeelover 29 May 2016, 15:51


People noticed my glasses at first but i was complaining of blurred vision before i got them so when i wore them the first time there were just a few questions/comments. The problem here is shipping, the glasses plus lenses are cheap in zenni but the shipping will be expensive. even more expensive than getting a new glasses plus lenses here. I got the glasses from a friend and saw her prescription doesnt have any astigmatism correction. At first i had a hard time on near objects after wearing the glasses, but after a few mins the discomfort went away. Now if i put on the glasses, i dont experience any discomfort anymore. In your opinion how many months will i use this to induce about -1.0 myopia. I also enjoy the blur and not only the glasses, a higher myopia is better but i think because of my age that is unattainable. Thanks again for answering my questions

Cactus Jack 29 May 2016, 10:10


If you are not having any problems with the OD -2.00, OS -2.50 glasses, I suggest continuing to wear them. Ideally, it will take longer and longer for your vision to clear after you take them off. When you can, I would suggest gradually increasing the power of your Right lens (OD) to first -2.50 and then -3.00 and maybe -3.50. Right now, with your actual prescription of OD -0.50, OS +0.50 you are over corrected OD -1.50, OS -3.00. With that much difference, you are probably reading with your Right eye and using your Left eye for distance without your being aware that you are doing it, in other words, Mono Vision. If the difference is great enough, the Brain may ignore the image from one eye entirely.

Vision actually occurs in the Brain, the eyes are merely biological cameras. If there is a difference between the clarity of the two images, your brain will select the sharpest image and use it as the primary and use any clues it can from the other eye to enhance the primary. The Brain can also improve a blurry image if it knows what something is supposed to look like. The Brain can even produce an image with your eyes closed. Ever had a dream? From a legal point of view, that is why Eyewitness Testimony is sometimes flawed because the person saw what they expected or wanted to see, not what actually occurred.

There is nothing really wrong with Mono Vision, many people use it instead of wearing bifocals or progressives when Presbyopia becomes a problem. However, there are two problems with Mono Vision at your age. One, it allows one of your Ciliary Muscles to be stronger than the other and Two, because you are using your eyes independently, you don't have good depth perception (3-D vision).

I hope I have not confused you too much. This stuff can be hard to understand. The thing that makes it hard is that Glasses or Contact Lenses cancel out or neutralize your actual Refractive Error with the opposite power lens. For example your Right eye has an actual error of +0.50 and your Left eye has a actual error of -0.50. If you want to wear -1.50 glasses, you have to create a +1.50 error in each eye. To to that, you generally have to initially go several diopters over your goal and then let it settle back to your goal. Initially, you do that with your Crystalline Lenses and if you are young enough and lucky enough, your eyeball will actually grow a bit longer and that becomes True or Axial Myopia. But the way, the distances involved are tiny, about 0.3 mm per diopter.


Soundmanpt 29 May 2016, 09:31


Your right I thought you meant that it was taking about 20 minutes for you eyes to adjust to your glasses when you put them. No it's completely different if your eyes don't need any time to adjust to them when you put them on but after wearing them all day that when you take them off everything is pretty blurry at first and after about 20 minutes your natural vision slowly returns. So the only questions I have is how well can you see with your glasses? For distance and close up? Do you feel as if your seeing better now with your glasses than you were the first day you wore them? Have you been wearing them constantly from the time you open your eyes until you go to bed or do you take them off quite a bit to rest your eyes? Since this I assume is the first time you have ever wore glasses i'm sure it feels strange wearing them now, but after wearing them for a week now you should be getting used to wearing glasses and they should be starting to feel a lot more comfortable as well. Since your a student and I assume your still in class what comments or questions have you gotten about your need for glasses? Anyway if your able to see perfectly with your glasses without any problem then there is no reason to order glasses with a lower prescription. Zenni and many other on line sources are international and ship everywhere in the world but I think it must be a problem at your end for some reason that you can't order glasses on line. You didn't say how or where you got your glasses from and how you know what the prescription is? Getting them from a friend is fine as long as they work for your eyes. My concern is only that they don't have any astigmatism correction in them for you to deal with. So if your glasses are comfortable and seem to be getting even more comfortable then just keep wearing them and see what results you get.

@CactusJack and Soundmanpt

Thank you guys for your advise but i think i misunderstood your questions before. What i meant with my last post is i adjust immediately to -2.0 and -2.5 glasses, and what i meant about the 20mins is when i take off the glasses it takes about 20mins for my eyes to become clear again. But i get your point about starting at a lower power of glasses first. Unfortunately i cannot order glasses online here but i found a way to get that lenses you suggested. with that misunderstanding cleared, do you still suggest the lower power lenses or should i continue with the -2.0 or -2.5?

Seeing what you say in your posts its pretty clear that your being over aggressive by trying to wear glasses that are too strong for your eyes. If it is taking 20 minutes for your eyes to somewhat focus with those glasses they really can't be that comfortable to wear full time which is most important. I have a feeling since you say you got your glasses even before you had your eyes examined to even determine what if any glasses you might really, that you got your glasses from a friend that gave you a pair of her previous glasses. One problem with wearing glasses from a friend is that you don't know if the glasses may also have some astigmatism correction in them and your eyes will never be able to adjust for that. Getting your glasses on line is really the best way and not very expensive I saw what Cactus Jack was suggesting you start off with and I couldn't agree more. Like he said the best thing to do is to order several pairs in the exact same frame but with different prescriptions in each pair. That way as your eyes adjust to each pair and you are ready to increase the strength of your glasses being the same frame no one will ever notice that your lenses are stronger except you. By starting out with weaker glasses as Cactus jack and I suggest you should be able to put your glasses on as soon as you open your eyes each day and be able to quite good with them for distance as well as close up without any problem. The main thing is with trying to induce myopia is to constantly wear your glasses from the time you wake up until you close your eyes at the end of the day. The fact that you would be happy if your able to induce to around -1.50 might be workable still. But to get to -1.50 at some point your probably going to be wearing around -3.00 glasses or more.

Always remember that even if your true need for glasses never reaches -1.50 you will still be able to wear glasses in that power or even stronger full time without any problem. So even if your still able to see the eye chart without your glasses who cares as long as your wearing the glasses you want to wear?

Cactus Jack 28 May 2016, 19:33


If there was ever a course of study that would almost guarantee myopia, it is to study the law. I would like to suggest that you start over. Inducing Myopia of any type is a bit like lifting weights. You don't start with heavy weights. You start with relatively light weights and do lots of repetitions.

May I ask the source of your glasses?

One of the tricks of getting increasingly stronger glasses is to stick with the identical frame. Very few people really notice changes in a glasses prescription, but they do notice frame changes.

You asked about a person with hyperopia Inducing Myopia. It can be done if they are young enough. their hyperopia is not too great, and they are motivated. Let me relate a true story.

Several years ago, I was contacted by a young man from Ireland, who had just started university. He had a very strong desire to wear glasses, preferably for Myopia. The problem was that he had several eye exams and was told that he did not need glasses. As you can imagine, he was very frustrated.

I suspected that he was not approaching the exam with the correct symptoms and suggested a very simple test, that he could do at home, to estimate his refractive error, if any. He did the test and it revealed that he had very mild Hyperopia. He had been reporting the symptoms of Myopia which the official exam revealed that he did not have.

I asked him to get another exam, this time reporting the symptoms of mild Hyperopia and that resulted in a Low PLUS prescription with a bit of Astigmatism. That exam yielded the information I needed to suggest ordering some low Minus glasses from Zenni. He ordered two pair. One was a -1.00 over correction and the other was a -2.00 over correction in the same frames. He started wearing the -1.00 glasses for everyday wear until they became so natural that he preferred his vision with them than without them (a month or two). He wore the -2.00s as much as he could at home and then switched over to them full time and ordered some -3.00 glasses, same frame.

When he became comfortable with the -2.00 glasses, I suggested that he book an eye exam, to gauge his progress, with an optical chain and wear the -1.00 glasses to the exam with a complaint that his distance vision was not very clear. That resulted in a prescription of about -1.50. I suggested that he not order glasses with that prescription, but keep on wearing the -2.00 full time or the -3.00 glasses as he could.

He gradually worked his way up to -4.25 and moved to a University in England. By then he knew what to do. I have not heard from him in several years.

You have had an exam that revealed that your actual prescription is OD -0.50, OS +0.50. I would like to suggest starting over with OD -1.50, OS -0.50. One of the problems you are having with the present glasses is that they allow your ciliary muscles to continue to work independently. They really need to learn to work together. You could do that by getting glasses OD -0.50, OS +0.50, but they can learn to work together and start working on your desired prescription at the same time.

I suggest that you order glasses with inexpensive frames, because you may only wear them for a month or two before going to a stronger prescription. Several of us use Zenni Optical. The offer some very low cost frames and lenses for simple prescriptions like your. I don't know what the cost would be delivered in Manilla, but here in the US they offer glasses for as little as US$6.95 with around $5.00 for shipping and around $5.00 for a low cost Anti-Reflective coating. All you need to order is a Credit Card, your desired prescription, and your PD. We can help you will all but the Credit Card.

Please let me know what you would like to do.

Im a female, im wearing the overcorrected glasses for about a week now. It takes about 20mins in my R eye for my vision to be clearer but in my L eye it only takes about 5 mins to make my vision clear again

coffeelover 28 May 2016, 16:24

@Cactus Jack

I got the glasses before i knew my true prescription. I noticed that this are blurrier in my left eye thus -2.5 in right and -2.0 in the left. I live in Manila and currently studying pre law. i feel that i can tolerate additional correction but im just afraid that my change in lenses will be noticable. Do you know anyone who was farisghted but induced myopia. i know -1.5 is just low but my age is against me but i still wish i could induce at least a -1.0 if the -1.5 is unattainable

Josh 28 May 2016, 10:45

hi coffeelover, since when you are wearing -2,00 -2,50 glasses? how long it takes to get clear vision? are you male or female?

Cactus Jack 28 May 2016, 09:52


At 23 it is unlikely that you can induce very much True or Axial Myopia. It depends on your genes. You might be able to induce some Pseudo Myopia, if you are willing to work at it. For practical purposes, both require minus glasses for correction.

The general rule for over correction is that you Add the same amount of Sphere over correction to each eye and copy the Cylinder and Axis (if any) EXACTLY. You did not mention if you have any Cylinder correction.

Your goal of -1.50 in both eyes is modest, but it will probably be difficult to not have a difference between your two eyes. A 1.00 difference is nothing to be concerned about. Your eyes are actually independent entities and it is common to have a difference.e

If you can tolerate it, you need more over correction than your goal to have much effect. You indicated that you are tolerating OD -2.50, OS -2.00 very well. At 23, you probably have lots of accommodation available even with the amount of studying most students have to do. With the OD -2.50, OS -2.00 glasses you are wearing over correction of OD -2.00, OS -2.50.

I have a few questions

1. Was the OS over correction difference, intentional?

2. What subjects are you studying?

3. Where do you live (country)?

4. Do you feel like you could tolerate some additional over correction?


coffeelover 28 May 2016, 08:02

Hi guys, im a 23 yr old student who is trying to induce myopia. my goal is about -1.5 true myopia for each eye. As i was reading this thread, i read that i should have my eyes checked first for the astigmatism prescription, PD etc. So i did, i ended up with a prescription of OD -0.5 and a farsighted Left eye OS +0.5 . I have a glasses that has a prescription of OD-2.5 and OS -2.0 which i can tolerate well and can wear the whole day. Can i still induce some myopia with my current prescription?

Cactus Jack 23 May 2016, 19:44


I really would like to hear from you.


Soundmanpt 19 May 2016, 09:09


As soon as I started reading your question about your friend that was into weightlifting and how her eyesight was affected the first thought that crossed my mind was also what kind of products she might be using in regards to her bodybuilding. It is far more possible to think that she was using some form of growth hormone and a side effect could well be the reason her eyesight has changed. A few years ago I often stopped on my way to work at a gas (petro) station for coffee. It was usually the same young lady I saw every morning taking my money for the coffee. I was surprised one morning to see her wearing glasses. Of course after complementing her on how nice she looked wearing glasses she told me that they were new and she was trying to get used to them. She said her need for glasses was brought on by a new medication she had been prescribed. It said on the label that blurred vision was a possible side effect. Until she started taking that medication she had never had any problems with her eyesight and then after taking the medication for a short time almost overnight her vision got blurry.

Cactus Jack 18 May 2016, 13:59


I don't think I have ever heard of additional muscle or fat occurring inside the bony eye socket to the point where it causes pressure on the eyeball, but that does not mean that it does not happen. Generally, Axial or True Myopia is caused by a mismatch between the total PLUS power of the eye's lens system and the distance form the back of the Crystalline Lens to the Retina. It varies with individuals, but the typical power of the eye's lens system is around +58 diopters and the distance is about 17 mm. It does not take much eyeball elongation to cause a fair amount of Myopia, about 0.3 mm per diopter. An increase of -3.00 would only be about 1 mm.

There are a lot of unknowns here, but usually, by 30, a persons genes would have stopped any eyeball growth. The only thing that comes to mind is that if a muscle builder increased their body weight by 75 pounds they might have been using hormone supplements or other substances that could have caused some eyeball growth. You mentioned that pregnancy can cause increased Myopia. That is believed to be caused by a suspected, but as yet unidentified "Eyeball Growth Hormone". There are many hormonal changes during pregnancy and it is possible that she took some hormones that had unintended effects. If her eyeballs have grown a bit, it is unlikely they will shrink if she loses muscle or fat.

I hope this makes sense.


observation 18 May 2016, 11:12

Could obesity contribute to myopia? I knew of someone who was really into weightlifting their 30's, , gained about 75 pounds of both muscle and fat in a total of a few years, she got her eyes checked after a while and added around -3 to their prescription. no extra pregnancies that could've contributed or anything. I wonder if the extra squeeze around the eyes would contribute to intraocular pressure and therefore induce more myopia. Even after losing Any thoughts on this?

Cactus Jack 15 May 2016, 22:28


I think we need to discuss the situation more in depth to make sure you have as much control as possible. Some ECPs lean toward under correction, believing that helps slow the progression of myopia. Often these ECPs are very reluctant to fit patients with their first pair of glasses. Others (depending on their situation), are encouraged to prescribe glasses to improve sales.

Can you tell me a bit more about where you got this recent exam? Did you feel pressured to order glasses? Some of the large optical chains are owned by an Italian Company that is VERY interested in selling expensive glasses.

Knowing what you know now, do you feel like there was reluctance to prescribe glasses at your last "official" exam? Will the exam in August be by the same ECP as you have seen before? Has there ever been any comment or suggestion that they would like to do a dilated exam (with drops)?

In the meantime, I suggest that you continue wearing Scott's -2.25 glasses when possible. you might try the -3.00 glasses occasionally to get an idea how well you tolerate them.

One of the things you need to be careful about is having too much of a prescription for your first glasses from your "old" ECP. At 17 or 18 it is a bit unusual to have an increase from 0.00 to -1.00 along with a prior history of not needing glasses. However, that could be explained by a heavy study workload in the later years of High School and preparation for University.

With -1.00 diopters of myopia, everything beyond about 1 meter should be a bit fuzzy. Are you noticing that without glasses, particularly first thing in the morning or in low light conditions?


CJB 15 May 2016, 19:56

Cactus Jack

I listened to you and have decided not get the -1.00 prescription filled. I will continue to wear Scott's glasses until my real appointment. I like the idea of complaining and getting my appointmnet moved up so I can start wearing glasses everywhere even infront of my parents. However I cannot help but wonder if I should just wait until August so I can induce even more myopia for the appointment. What do you think is the better option?

The appointment was sort of like what you said with a few differences.

Cactus Jack 15 May 2016, 17:57


To continue my earlier post, The bundle you have to get past next is it get your parents involved. I am assuming that one of your parents either made your August annual eye exam appointment or you did with their blessing as one of the items you did each year before school starts in the fall.

Now that you have achieved one objective, you have a decision to make. You can begin to complain about some distance vision problems such as: difficulty reading a menu board, distant signs at night, white board, or reading small text on a TV (more than 6 feet away) and ask if the August appointment can be moved up. Or, you can continue to wear Scott's glasses, whenever possible, in hopes of going beyond -1.00 for the August exam. You could, of course, wear the -1.00 contacts, but there is a lot of paraphernalia associated with contact lenses that might be pre-maturely discovered. Once you "officially" start wearing glasses, you can get just about any prescription you want, online, at reasonable cost, but as long as you are living at home, you have to be very careful about how you pay for the glasses and where they are shipped. Few people understand how inexpensive and convenient it is to order glasses online. Because they are inexpensive, they assume they are of low quality, which is not true if you order from the right places.

I want you to understand that the best description of my role in this is that of a Coach. You have to play the game and you are where the action is. I can only make suggestions. You don't have to answer to me or even explain why you made the decision you did. No mater what you decide, I respect your decisions and your right to make them.

When you get an opportunity, I would like to hear more about your eye exam and how closely it followed what you expected to happen after reading "How to study for an eye exam" and our conversations.


Cactus Jack 12 May 2016, 05:46


Before you pick out some frames, check out the frame offerings by Zenni Optical. You probably should get your first glasses from a local source. However, you need to learn how to order glasses from an online retailer for two reasons. 1) The huge difference in price and 2) you can order any prescription you want without an official prescription.

If you choose a frame similar to those offered by Zenni, you can get glasses with a different prescription and it will be probably not noticeable. I know it is very exciting to actually get an "official" prescription, but I think you need to re-think getting the prescription filled right now. You have the biggest hurdle to still get past. Getting and official "official" prescription as a result of a family scheduled exam. Glasses are going to cost several hundred dollars from a local source and if you are going to spend that kind of money, you need to be able to wear them full time.


CJB 12 May 2016, 00:56

Cactus Jack

Hi!! So I had my appointmnet yesterday, and now I am officially a glasses guy!!! Turns out I really have induced some nearsightedness! I did not have the glasses yet because I am going back with Scott tomorrow so we can chose the frames together. My prescription is -1 in both eyes! Can you believe it, I am finally going to have my own glasses! I cannot wait! I spent most of the day with Scott, and he has given me his next glasses, they are -3.00 and -3.25. I also got sized for contacts, so I can get contacts and glasses. I can wear the contacts under the new glasses Scott's given me after I get used to them!

Cactus Jack 11 May 2016, 03:43


Wish you the best. You may be encouraged to order glasses, but please do not until we chat. You can look at frames, but think of a good reason to have difficulty selecting. Be sure and get a copy of your prescription so we can analyze and strategize.

Maxim 03 May 2016, 14:50

Why so pessimistic? Perhaps she's got everything, at least the photograph of her glasses looks very convincing. It would not be her first action to write us here. Many of the 16 yr kids have bank cards, if not, they have friends, who can arrange such orders. I know this from experiences from my kids and their friends, they always or at least very often find solutions for everything.

And, this opinion might not be what we call 'politically correct: what would you prefer as a father:

a son or daughter experimenting with GOC (it might be permanent or even go away after a certain time), or a son or daughter experimenting with drugs? I would prefer the GOC idea!

And by the way, do you know, when I practiced GOC? It was when one of my children had a -4 myopia at the age of three ((now -9 at the age of seventeen), and I entered again in GOC experiments only to find out, how she was seeing and feeling (I was at +3.00 at that time).

Soundmanpt 03 May 2016, 08:58

There has been no response from Rebecca since April 19th. At the time she was deciding on how much prescription she should get for the glasses she was planning on ordering on line. Since she says she is only 16 I wonder if she even has a credit card which you need in order to place an order for glasses. Sadly Rebecca could just be a fake.

Cactus Jack 02 May 2016, 13:07

Generally, it is men wishing to increase their myopia, but occasionally a woman will ask about it. Of course there is no way to know who is auditing the conversations. The principles apply to both genders, however women sometimes have an advantage by being able to become pregnant. If there is a genetic tendency for myopia, often pregnancy will cause the production of "eyeball growth hormones" which can increase myopia.

The most recent inquiry is by Rebecca, with several posts below.


 02 May 2016, 12:44

Are there any women in here that are currently trying to induce myopia or any that are considering trying to increase their prescription or to create a need for glasses? It seems like mostly men doing it for some reason.

Cactus Jack 01 May 2016, 08:05


That is OK. I was fairly sure that if you had any astigmatism, it would not be very much. Astigmatism is typically cause by uneven curvature of the Cornea. The actual cause is unknown. Astigmatism usually develops very slowly and it is likely that Scott did not have any cylinder correction in his -2.25 glasses. An easy test is to hold the glasses 10 to 12 inches from your eyes and rotate the glasses while looking through each lens individually. If there is cylinder correction in the lens, objects seen through the lens will change shape as you rotate the glasses.

Not all ECPs use the Red/Green test. I just wanted you to be aware of the test and its purpose if you encounter it.

Remember, the May 11th exam is primarily to get an "official" measure of progress and gain experience. Hopefully, you will get a prescription..

Have you decided on the visual symptoms you are going to report?


CJB 01 May 2016, 07:17

I tried astigmatism tests, and feltnlike there was none. Also, I tried to do some more reseaech on the red and green thing, but could not rind anything helpful.

Sorry for responding so late, there was conatruction in our neighborhood and it yook our electricity.

Cactus Jack 28 Apr 2016, 11:31


I would also like to suggest that you check out some of the on line astigmatism tests. You can find them by doing a Google search on Astigmatism Tests.

You should try the tests both with and without the -2.25 glasses and let me know the results.


Cactus Jack 26 Apr 2016, 18:06


Did you ever read the piece I wrote on "How to study for an eye exam"?

I don't think I mentioned it in the piece, but at some point you may be shown the eye chart with a red and green filter over them. The purpose of this test is for you to compare the sharpness of the letters behind the green filter and the red filter. Because of the way light rays are bent by lenses green will focus at one distance and red will focus at another. The actual goal is for the letters behind each filter to be equally clear. However, if you need more MINUS, the letters with the Red filter will be clearer than the letters with the green filter. You have to be a little bit careful IF this test is used because you won't have much time to think about it and you probably can't get more than one step beyond equally sharp (-0.25) without raising suspicions.

Generally, examiners start with too much PLUS (not enough MINUS) in Sphere and gradually increase the minus until you can read the 20/20 line, 20/20 is "normal" vision, but not the best. 20/15 is actually closer to the best. When you see both the red and the green equally clearly, you might just say that you think the Red might be a little better. The examiner may let you try one step more, but be careful with that. 20/10 vision is very rare, though some people have it.

You don't want the examiner to dilate your eyes. If they ask, turn it down saying that it will make it hard to focus close and you have to do homework tonight. A dilated exam is actually the best for accuracy, but you are not looking for accuracy yet. If you want to do a bit of research on the Red/Green test, look it up on Google.

Cactus Jack 26 Apr 2016, 13:56


Haven't heard from you lately. Are you about ready to start preparing for your Eye Exam on May 11?


Soundmanpt 20 Apr 2016, 08:10


Clearly you have been given much advice as to how strong you should get your glasses when you place your on line order. In the end it appears that your just going to have to place your order with what you feel like your eyes can tolerate. You certainly seem to be determined which will be a big advantage even if the glasses seem a little strong when you get them. I'm sure I don't have to tell you but what ever power you decide on be sure to put in all the astigmatism part of the prescription that you got with your last eye exam. Now I have a question since you got your free pair of glasses with your insurance in the prescription you just got. So i'm sure that you will likely be wearing your new glasses until you get your on line glasses. Even if you order them today it could take up to 2 weeks to get those glasses. Then when they do arrive and start wearing them how will you explain why you got new glasses after only having this pair for a couple of weeks. Also your a young girl with most likely lots of friends and I am sure as soon as your friends see you wearing the glasses you just got some of them are sure to want to try your glasses. But then in about another 2 or 3 weeks your going to have whatever glasses you decide on which is sure to be considerably stronger than the ones you have now no matter what prescription you order. Now when these same friends see you with your on line glasses there is a good chance they will want to try them on as well. I think there is a good chance they might notice that your glasses are much stronger than the ones you have on now? And how do you answer why you got new glasses after just a few weeks?

I know you have only had your new glasses for a short time but it seems like your eyes are adjusting to them pretty well. I know that their not really any stronger than your previous glasses but the increase in your astigmatisms is something different for your eyes to adjust to.

DS 19 Apr 2016, 21:17

I think the biggest problem with pushing too much minus on Rebecca will be esophoria from accommodating. I doubt that a primary problem would be from not having enough accommodation.

This will cause strain with a likelihood to present as headaches.

Over-minusing "correctly" requires base out prism to compensate. (Yes, this would further increase the outer edge lens thickness, likely a desired outcome.) For continuous use,keeping it simple, and keeping it inexpensive, I would stick to -2D extra, leaving room to "grow" to meet the urge later.

Cactus Jack 19 Apr 2016, 18:15


I suggest you review the conversations with CJB on this thread. He is about your age, with similar desires, and has been wearing a friends -2.25 glasses for a few months, whenever he can. He is using a simple procedure we suggested to measure his progress. He appears to be making measurable progress and is planning a "practice" Eye Exam in May, as a rehearsal for his scheduled pre-school exam in August, if I remember right. You might find it interesting.

If you don't understand what you are doing, you may give the wrong answers to the questions you are asked prior to an exam. Some years ago, one of our posters really wanted to get some MINUS glasses, but had been unsuccessful. With a few simple tests, we were able to determine that he was actually a little bit Hyperopic, but not enough to require external correction. With some coaching, he actually got a prescription for low PLUS glasses AND some correction for very mild Astigmatism. With that information, we were able to help him order some low cost MINUS glasses and develop a strategy for increasing his prescription. His ultimate goal was -8.00. The last we heard from him, he had worked up to wearing "official" -4.25 glasses full time and was continuing his University studies.

Making this happen for an individual who is still living at home requires a lot of planning and a little subterfuge, but it can be done. It is easier to do if you have started University, away from home.


Specs4ever 19 Apr 2016, 17:30

From the ones I have actually communicated with Rebecca, the anecdotal evidence has been that, while initially a bit of a strain, after about a 2 week period there has been no problem for them to get used to the glasses. They could read, with slight difficulty from the beginning, and depending on the motivation they all adapted to the over correction fairly easily. The biggest thing to remember is that you ned to leave the glasses on all the time and do not try to go without them for any reason. At your age you should be able to adapt fairly readily because your cillary muscles will do the work once you train them.

cactus Jack 19 Apr 2016, 15:18


It is impossible to predict how much over-correction you can tolerate. It depends on too many factors. The primary factor is the strength of your Ciliary Muscles. For their size, they are typically the strongest muscles in the body.

Wearing more MINUS than you need causes your Ciliary Muscles to squeeze your Crystalline Lenses to increase their PLUS power.

In effect, the first step in Inducing Myopia is to Build-Up the strength of your Ciliary Muscles. It is really no different than lifting weight to build up muscle strength. The key thing is that you don't start by lifting very heavy weights because that will strain the muscles and actually slow down the muscle building process. To give you an idea of what is possible with motivation and dedication, we have been able to help a man, in his late 20s, work his way up to where he was wearing -20 glasses or -12 diopters of over correction. He was able to read comfortably with them (another 2.50 diopters). He started with Axial myopia in the -4.50 range.

At your age, you may be able to induce some Axial or True Myopia, but you have to start with over correction, which initially causes Pseudo Myopia. If your Genes will permit it, that can cause the production of an Eyeball Growth Hormone (believed to exist, but as yet un-isolated and identified) which will cause your eyeballs to grow and increase your true Myopia.


Rebecca 19 Apr 2016, 15:04

I just realized I forgot to answer your question, Soundmanpt. I think I would be most happy with -6.25 or -6.5 (or one in each eye), but anything between -6.00 and -7.75 would be fine. I don't know if this is wishful thinking or what. It seems like it'd be really hard to get that myopic (considering I'm starting from -0.75 at best).

Rebecca 19 Apr 2016, 14:53

Yeah, that is a good point. I am willing to have some adjustment period, even a few months long, as long as it results in more myopia. I just don't want to have any blur (or minimal blur) when doing close work. Having never worn lenses stronger than -2, I don't know exactly how things would look. But for the record, -2 was fine and I would consider it a little weak to start off with.

I'm on the bus to class now after getting my new glasses. I definitely notice the astigmatism correction, but it hasn't given me any strain or headache yet. The only thing is that the floor looks a lot closer, but I remember that happening with my first prescription glasses and I don't think it took long to get used to.

Here is a picture of the glasses, if anyone's curious (odd angle because I'm on the bus):

They are a very generic plastic frame and insurance paid for them wholly. I'm glad I won't have to wear them once I get some online because they are quite large, but I will wear them until then.

I think I am inclined to agree with Specs4ever about the prescription. He has anecdotal evidence, and when I did wear -2, they were quite underwhelming. I'm also impatient and cheap, and his method of going up 3D right away is definitely the cheapest. I'm not sure if it's any faster though, and it will probably be more painful at first. I would like to try to order the glasses tonight or tomorrow morning, so please keep providing feedback.

Soundmanpt 19 Apr 2016, 12:05


I'm sure you have to feel conflicted as to what prescription to order for your glasses. But the problem is there isn't really anyway to determine how strong of a prescription your eyes can tolerate and adjust to. It could be that Specs4ever is right and your eyes may be able to tolerate that much over correction without too much of a problem. Honestly even if you order weaker glasses like I suggested I think you might still get some headaches as your eyes are adjusting to them. In order for your eyes to become more myopic you do have to put stress on your eyes which by wearing your glasses and using your eyes as you normally do should be enough stress. Something you need to know is that your new "real" prescription now has quite a fair amount of astigmatisms in both your eyes. This is almost certain to cause you problems even if you only got glasses for what was just prescribed to you. Your current glasses only have a very slight astigmatism correction in your left eye as I recall. Now don't be surprised when you first put your glasses on that you might feel somewhat dizzy and the floor may appear to be slanted or even spinning. That feeling will soon go away after you have your glasses on for a short time. Something that hasn't been asked is how strong do you want your glasses to be for what you would consider to be the perfect prescription for your eyes?

As long as you can get a free pair of glasses then yes you might as well take advantage of that. Actually if you do get them you might as well wear them so your eyes can adjust to the astigmatism corrections you now have. That way when your ready to order glasses on line and get them you will already be adjusted to the astigmatisms.

Rebecca 19 Apr 2016, 10:39

I am quite conflicted now about which prescription to go for. Like I said, I do want the strongest possible that won't cause headaches, but I'm not sure what exactly that would be.

Specs4ever, have any of the people you've been in contact with complained of severe eye strain? Have they been able to wear the glasses full time when doing close work?

Hello Soundmanpt, the reason why I'll get some glasses with my real prescription from LensCrafters is that my insurance should pay all of it. If this turns out not to be the case, then I will skip that part. I'm going there now to find out. It would indeed be possible to go to another optometrist next time, but I do like my own, so I would probably just say I lost/broke my glasses and decided to come in for an updated prescription before getting new ones.

Also, I actually have been wearing properly prescribed glasses since June 2014 (before that, it was whatever glasses I could find), but I simply cannot remember the exact prescription. It wasn't something I paid much attention to at the time. Likewise, I can't really remember how look it took my eyes to adjust, but probably only a month. I can't imagine it taking much longer than that, anyway, as I probably would've noticed if it did.

Thank you for all the advice CJ, Specs4ever, helpful, and Soundmanpt.

Soundmanpt 19 Apr 2016, 09:42


I am really quite surprised that your eyesight wasn't at the very least at -1.00 / -1.25 since you have been wearing glasses full time for the past 2 years with that prescription. As you say your eyes appear to be rather stubborn about being changed. I was going to question you on how diligent you were about wearing your glasses during those 2 years but you said that you only had your glasses off long enough to clean them and when you were sleeping. So that should have been more than enough for your eyes to change. But at least by wearing your glasses you no longer have perfect vision anymore and your right eye almost got to the -1.00 and with your astigmatism is actually right at -1.00. But surprisingly your glasses had barely any effect on your left eye. But with your astigmatism added your seeing about the same as being between -.50 and -.75 as a blur factor. I want to question why you want to waste over a $100.00 dollars on glasses that you really have no intention of wearing from Lenscrafters? That money would be better spent on getting several pairs of glasses from Clearly or Zenni where your money goes a lot further. If your planning on getting your eyes checked every year or so that's fine but maybe next year just plan on going to a different place to get your eyes exam and that way you don't need to even bother with getting glasses in the prescribed prescription since you won't be wearing them anyway. Like Cactus Jack said it would be a very good idea that when you order your glasses on line that you get maybe as many as 3 pairs since the are so inexpensive, with the exact same frame. As since your eyes are already completely used to your -1.00 - 1.25 glasses the first you might want to start wearing should be OD -1.75 -.50 110 / OS -1.75 -.75 175. Once your eyes are fully adjusted to wearing these glasses comfortably then you would switch 2 the second pair which would be OD -2.25 -.50 110 / OS -2.25 -.75 175. And the 3rd pair something like OD -2.75 -.50 110 / OS -2.75 -.75 175. If you order your glasses from Zenni ( you can easily get all 3 pairs for under $50.00 total. By guess is that you should be able to go from one pair to the next after about 3 months time or maybe even less depending on how much your eyes are willing to cooperate. When you first started wearing your current glasses how long did it take for your eyes to adjust to them? How did you get the glasses your wearing? Since you seem a lit unsure about the prescription either being -1.00 for both eyes are -1.00 / -1.25 I have a feeling you may have gotten them from a friend. The suggestion of going straight to over -3.00 for your glasses I think is a a bit risky. That's a lot of over correction and it could make trying to read or see things close much too difficult for you. I'm sure with your young eyes seeing distance wouldn't be much of a problem but you want your eyes to be reasonably comfortable while your working to make them more nearsighted.

My thoughts were not to wear your new prescribed glasses you ordered anywhere near parents friends etc but to wait until you get your recommended extra strength glasses from another supplier. This is to avoid ?s as to why you are wearing stronger glasses within days of getting another pair after your test so quickly. This is even more important if you go for well above that prescribed at the test. You have to box clever!

Specs4ever 19 Apr 2016, 07:08

Hi Rebecca. With all due respect to Cactus Jack I have to say my thoughts differ from his. My suggestion would be to go for a full -3.00D over your real prescription. My reasoning for this is that I have been in private contact with a number of young ladies who wanted to increase their prescriptions and the -3.00D seems to be the right number to help them do this. For the first 3 months it seems that they do have a little bit of work to maintain focus through this over correction, but after about 3 months they have gained around -1.00D in their real prescription. Then after about a year goes by they will have gained about -2.00D. At this point they add the -2.00D they have gained to their original -3.00D over correction and go on for another year. By the end of a 2 year period they generally have increased by at least -3.50D, sometimes more.

I recently moved not to far away from you, but have not bought anything from Clearly yet. I must look at their prices. If you want to you can e mail me. I hope you do as I am interested in helping anyone who really wants to do this.

Your prescription for glasses should then be -3.75 x 0.50 x 110 for the right eye and -3.25 x -0.75 x 175 for the left.

Cactus Jack 19 Apr 2016, 06:46


Your present prescription is

OD: -0.75 sphere, -0.50 cyl, 110 axis

OS: -0.25 sphere, -0.75 cyl, 175 axis

You should be able to start with an increase of -1.00 Sphere in each eye.

OD: -1.75 sphere, -0.50 cyl, 110 axis

OS: -1.25 sphere, -0.75 cyl, 175 axis

Notice that I increased the Sphere by -1.00, but DID NOT alter the Cylinder or Axis. Also I added the same amount in both eyes.

An OO might be able to notice a change in what are called "power rings" with the increase. The frames you choose and the edge treatment can affect the appearance of the power rings. Power Rings are actually cause by internal reflections of the edges within the lens. They can be minimized by a frame that does not admit much light through the edges of the lens. For example, the style frame your friend is wearing has open edges, but his prescription is pretty low and the edges are not very thick and while there may be some Power Rings if viewed from some angles, they are probably not very obvious.

Be careful about being too clever about returning glasses. They will probably require some proof that the glasses were incorrectly made from an ECP before they will re-make them or refund your money. At this point, you know enough about how all this works to be dangerous. Unlike many items you buy, glasses lenses cannot be sold to someone else. They are custom made for YOU, to your prescription, and have been cut from the specially ground "lens blank" to fit your frames.


Rebecca 19 Apr 2016, 00:06

Thanks for reminding me to get a pair with the real prescription. I'm going to go back to LensCrafters tomorrow and get it filled with a cheap pair (my insurance only pays $118). Then I'll order stronger ones online. I tried Zenni but I think with the exchange rate and shipping, it's about the same price as Clearly.

What should I start with for the increased prescription? I kinda want to see fast results and also not have to buy that many pairs of glasses due to cost, so I think the highest I can currently handle is best.

With the return policy at Clearly, I should be able to exchange a "wrong" prescription pretty easily anyway.

Cactus Jack 18 Apr 2016, 20:14


I forgot to mention that you will need a pair of glasses with the prescription you just got. They serve two purposes.

1. The provide a measure of your progress in Inducing Myopia by comparing your vision with these glasses and with your glasses with increased - Sphere.

2. At some point you will want to another "official" exam, perhaps by the same ECP as you used for this exam. You will need to wear the last prescription you got from him/her to avoid hard to answer questions.

It is likely that you will need an "official" pair of glasses for a while to allow your parents and friends to get used to the idea that you need glasses. Once you get over the "new", you will have a lot more freedom to do what you want without getting too many questions.


Cactus jack 18 Apr 2016, 20:06


You do have some myopia and some astigmatism. It is very likely that your myopia will increase pretty much on its own, but you can encourage it. Astigmatism is a different animal. It is caused by uneven curvature of the front surface of the cornea. It actually changes very slowly on its own.

Most changes are in Cylinder and Axis are caused by the patient's inexperience. That portion of the exam is the most subjective with the final Axis number depending on the patient's skill in judging relative blurriness. A difficult task even for a person who has had many eye exams. I wrote a post "How to Study for an Eye Exam" where I covered a technique I use to "fine tune" the axis.

If you have not ordered glasses yet, I have a couple of suggestions.

1. Check out inexpensive frames on the Zenni Optical website. If you want to Induce some additional Myopia, you are going to need to order several pairs of glasses with gradually increasing sphere. If you can keep the same or nearly the same frame style, few people will notice the increase.

2. If you order some glasses locally, try to plan ahead and select a frame that you can duplicate on Zenni.

3. Depending on several factors, you may be able to order a pair of glasses from Zenni for as little as US$6.95 plus shipping. Unless you have plenty of resources, you will appreciate the low cost for either Inducing Myopia or doing GOC.


Rebecca 18 Apr 2016, 18:46

Thanks for that link, I'll keep it in mind. I think for now, as some others have suggested, it's probably best for me to just get some stronger glasses. I also can't really afford contacts at the moment, but I am interested in trying them eventually, and DaySoft looks good.

I went to the Clearly store in Vancouver today, and found a couple of nice frames. I'm going to buy one of them as soon as I know what prescription to use. The maximum strength for free lenses (1.59 index) is -3.75. I've posted my new real prescription (which is weak and disappointing and frankly perplexing) a bit earlier today.

To reiterate though, I have been wearing -1 approx (I believe the left was -1.25 but I don't have the script anymore) since June 2014. So I think when increasing my script, it makes more sense to use that as the base measurement rather than my actual myopic correction that the doctor gave me today. My eyes are apparently quite stubborn and don't want to stretch, or maybe taking the glasses off to clean them/sleep is what's making them go back to normal.

for buying CLs - excellent supplier, cheap, no questions asked.

Rebecca 18 Apr 2016, 12:37

Hello again everyone. I have now finished my exam. I was reading all your posts up until the exam and I'm very thankful for your advice.

So my prescription is a little odd. I blame the autorefractor. It went so fast that I wasn't able to blur my vision.

OD: -0.75 sphere, -0.50 cyl, 110 axis

OS: -0.25 sphere, -0.75 cyl, 175 axis

I'm quite disappointed about the lack of myopia, but at least that can be changed by ordering online. I'm surprised at getting astigmatism in both eyes now, as I only noticed it getting worse in the left, but it makes sense.

Also, after the technician set up the phoropter it said my PD was 61.5, but my prescription says 59.

Soundmanpt 18 Apr 2016, 09:14


By the time you see this you may already be on your way to get your eyes examined. But if not I also want to suggest that you don't try and do any pretending while your getting your eyes examined. I actually think that when you last got your eyes examined you really did need the -1.00 prescription you got. It is really not easy to fool an optometrist into getting glasses. Even harder if they dilated your eyes. If your vision had really been perfect except for the very slight astigmatism you have in one eye the glasses you got would have felt on the strong side when you started wearing them. If you have been wearing your glasses full time since you got them by now when you take your glasses off you shouldn't be able to see things like the board at school very well without your glasses even if you didn't really need glasses when you got them. Your being 16 years old your eyes with constant wear would by now be completely changed to at least that -1.00 prescription by now. So i'm very sure that once they take your glasses from you your not going to be able to much of the bottom lines on the eye chart. So there is no danger that your eyes are still perfect if they even were before. To be honest it would not surprise me at all if get old that you need your glasses changed because they need to be a little stronger. Your already certain to need at least your -1.00 glasses and they may just want to sharpen things up for you by writing you a prescription for -1.25 or even -1.50 glasses. But even if they don't give you an increase like you say, all you need to do is come home and go on line and order whatever glasses you want. You asked about what prescription you should order? Because of your youth your eyes should be able to handle almost anything you put in front of your eyes. But it is still better for you eyes to only go up in small steps and also so questions won't be asked about your deteriorating eyesight. It is very normal when you get glasses at 15 that your eyes will just continue to worsen each year after. So your getting your eyes examined which you are and getting new glasses is almost expected to happen. Anyway I think if you don't get a real change in your prescription from you eye exam then your eyes should do just fine with -1.50 or even -1.75 glasses. That would be close to what one would expect if you were to get an increase. This may not seem like much of an increase but you would be amazed at how much more blurry everything would be be without your glasses once your eyes got adjusted to them.

I really don't think GOC is a good option for you. Your wanting something that you can wear on a daily basis and in your case GOC would be much too tricky. Let's just say you decided on wearing -4.00 glasses along with your contacts which by the way aren't as easy to get anymore. In fact I don't think you you can order contacts without having an actual doctors prescription from Clearly Contacts anymore. Also once you started being seen wearing your -4.00 glasses you would be forced to wear them all the time everyday and night. You really shouldn't wear contacts that much and what happens on day when your eyes just won't allow you to put your contacts on. You could never wear your -4.00 glasses without the contacts. There will be days like that. What if your at school and something gets under your contact and you have to remove it. Then what? You couldn't very well go back to wearing your -1.00 glasses anymore. GOC is a better option for people that are past the age where their eyes can be changed by wearing stronger glasses. In your case inducing is the better option. Even though you don't seem to think that wearing your -1.00 had any effect on your eyes until recently, I think you just weren't noticing the change because if you were wearing your glasses all day and only taking your glasses off at bedtime it makes sense that you were still able to see pretty well without your glasses looking around your room. Your glasses are better suited for helping you see things at a greater distance then just across your room. But if you recently started to notice things being blurry I don't think it's because of your astigmatism getting worse becasue astigmatisms don't usually change very much if at all, but much more likely that your distance has changed and you even need a very real increase. I will be very interested in seeing the results of your eye exam.

DS 18 Apr 2016, 08:01


I think you want an accurate exam (especially important if considering GOC). Ordering the glasses can be somewhat independent.

And, yes, stacking low power lenses is approximately the same. At 16, -2.00 should be no problem for you if your vision is mostly normal.

Rebecca 18 Apr 2016, 07:27

Cactus Jack,

Hi, I've got my exam in about 3.5 hours. I've been up all night reading this site, quite nervous over the idea that they might give me a weaker prescription, or find out I don't really have myopia at all (or at least not enough to require correction).

I found an old pair of specs from a friend, I'm not sure on the prescription but I'd guess about -1, like mine. I've been wearing them simultaneously, as silly as that sounds, but am I correct in assuming that this would effectively be a prescription of -2?

When booking my appointment, I neglected to ask about contact lens fitting. I suppose I will mention it as soon as I get there, and see if they have enough time to include it.

Anyway, thanks for your reply, I'll look forward to updating you all sometime after 11:30 am pst. BTW, I live in Vancouver, Canada.

Cactus Jack 18 Apr 2016, 07:04


It is probably all late to offer any suggestions for the exam. Ideally, you want the most accurate exam from the ECP, particularly for your Astigmatism. You can adjust the Sphere correction, but you should never adjust the Cylinder and Axis.

Please post your new prescription and we can go from there for Inducing Myopia and for GOC.


Rebecca 18 Apr 2016, 01:17

Hi everyone, I am 16 years old and currently wear glasses for mild myopia, but would like to increase my prescription.

I last saw the optometrist in June of 2014 where I got a prescription of -1 in each eye with -0.25 astigmatism in the left eye. The astigmatism is real but I think I mostly got the myopic prescription from lying. They made me look through the machine where you stare at an image, which I knew would instantly tell them my vision was fine, so I blurred it intentionally. Unfortunately this gave them an extremely poor vision reading, and they were suspicious, so they dilated my eyes. Somehow I still ended up with a prescription though, mostly by choosing the blurrier image when they asked which one looked best, and by intentionally getting letters wrong on the Snellen chart.

I have been wearing my prescription glasses constantly since then, but haven't noticed any changes in my eyes until a couple months ago. I am going to the optometrist in about 10 hours, and I hope my prescription has changed. I feel like it's mostly the astigmatism getting worse, unfortunately, and I doubt I'll have much change in myopia.

So, when I get my new prescription, I am going to order glasses online. How much strength can I safely add? For example, with my current prescription of -1, would it be okay to change that to -1.50? I want to make my eyes keep adjusting to stronger prescriptions.

I also have some reading glasses of +1.25 and +2.50 but I don't know what these would be useful for.

CJB 14 Apr 2016, 21:19

Cactus Jack,

Sorry, dor got to answer yiur question about when my appointment is. It is at 3:45 pm.

CJB 14 Apr 2016, 21:18

Cactus Jack

I have not had the time to check my vision with the +1.50 glasses, but by just estimation, I would have to say I have made some more progress recently because in the last weekish I have noticed that without Scott's glasses things have gotten a bit fuzy. The other day we went to taco bell, and I found myself having struggling trying to read the menu from the back of the line. As we got closer, I noticed that I really had to focus on what I was trying to read in able to see it. Hopefully I can do another test with the +1.5 glasses for you tomorrow or the day after.

Cactus Jack 14 Apr 2016, 20:14


Things have been very hectic this week. They should settle down some about mid next week. That will give us about 3 weeks for some coaching.

How are you doing with the -2.25 glasses and occasionally checking your vision with the +1.50 glasses? You might occasionally check your vision in the morning and then after wearing the -2.25 glasses as much as possible at the end of the day.

What time of day is your exam scheduled?


CJB 13 Apr 2016, 12:49

Cactus Jack,

I made my appointment for May 11th! can't wait!

Soundmanpt 07 Apr 2016, 14:09


She has managed so far not wearing her glasses full time mostly because her eye that was only -.75 SPH -1.00 CYL, which I assume might be her left eye since you listed it 2nd, was still providing her with good enough vision that she could get by without her glasses. But even with your idea of increasing her glasses a bit more her vision in that has deteriorated enough that she is going to find it much harder to see without her glasses anyway and with the additional -.25 your planning on adding on her glasses are going to be twice as strong for that eye now. Generally speaking many people once they reach -1.50 often start wearing their glasses much more often if not full time. And given the fact that she has a fair amount of CYL in that eye her glasses are really going to be much closer to being -2.00 in that eye. Her other eye including her CYL is more like -2.25 when you get her those glasses you plan to get for her. The good news is for you that i'm sure her optometrist has told her that her eyes have gotten more nearsighted so she shouldn't have any reason to question her glasses because i'm sure she knows that with new glasses her eyes re going to have to adjust to a change in prescription. Shes only 24 so young enough that her eyes won't have much trouble adjusting to her new glasses and I think as soon as her eeys adjust she is going to quickly find out that when she takes her glasses off things are much more blurry than they were before with her current glasses and she will almost certainly be wearing them much often and most likely full time which is exactly what your wanting. Of course remember it will help considerably if you tell her how good she looks wearing her new glasses.

Dan 07 Apr 2016, 08:29

Dan 07 Apr 2016, 08:26



N0 actualy. She doesnt want to wear her glasses full time until now. I hope has to wear them with new prescription. I like her wearing her glasses full time.


Soundmanpt 07 Apr 2016, 07:43


Since she is already getting an increase I don't think she would have any reason to question her new glasses if they were -.25 stronger than prescribed in each eye. But I think going anymore than that might be pushing it and i'm sure you don't want her to question her new glasses. I assume your wife already wears her glasses full time? I'm sure she is used to getting increases and knows when she gets new glasses it always takes a little while for her eyes to adjust to the new prescription.

Likelenses 06 Apr 2016, 23:49


Depending on her age.she can probably handle at least -.50 overcorrection for each eye.

I thought of ordering -2.00 -0.50 and -1.5 -1.00 .

Will it be noticble to her? Will she have problems with eye sight?

Thought of buying sunglases as well.

Please give your ideas.

Loss of a child can destroy a family. It almost did mine when my little sister contracted Leukemia when she was about 15. I was 22, out of college and in the Army. My little brother was about 7 and I am convinced that it harmed him pretty badly psychologically.

Do you have any other Brothers or Sisters?

I have a pretty solid relationshio with my parents, we talk about everything with each other. Due to recent events though, there is not much talking going on in our house. Everyone has sort of been keeping to themselves since the funeral. At the beginning it seemed like we were going to get closerz but then after the funeral it was like being around one another just reminds us of the he loss, so we have sort of been keeping conversations to a minimal. My dad is business man, and my mom basically analyzes people's sleep, she is the person that conducts those sleep studies.

Cactus Jack 05 Apr 2016, 18:52


When you go for your "official" exam, you absolutely DO NOT want to wear any corrective glasses or even mention that you have been wearing any vision correction. Your ECP needs to be the one that analyzes the symptoms you report and uses his skills and tools, exclusively, on this particular exam without any obvious help from you. All tis vision stuff needs to be a mystery to you, but a few good questions can't hurt to demonstrate normal curiosity. The exam will be a semi-passive exercise.

You want him or her to decide that glasses would be appropriate, no matter what their prescription. That will be your official license to wear glasses and it will be readily apparent to your parents that you need vision correction.

I'll tell you how to deal with the trial exam(s). If they are successful, we may want to move the August exam up.

May I ask your relationship with your parents. Do you have casual conversations with them to talk about things you don't understand. May I ask your parents occupations? That may help phrase your questions.


Cactus Jack 05 Apr 2016, 18:37

Congratulations, you have been successful in more ways than one. We can probably advise you. We understand your desires and in general, we are not judgmental. Your genetics are a big factor in your potential success. If you have been following some of my conversations with CJB, you will have an idea about what is involved.

You have mentioned your age and that is a VERY important factor. I assume that you are still a student, but probably nearing graduation. Please correct me if I am wrong.

May I ask where you live and what are your future plans regarding University or learning a trade? What things are you interested in? Do you do much close work or very much reading? Do you play any sports?

These may seem like strange questions, but the more I know about you, the better suggestions I can make. You know how to contact me privately. Please feel free to do that if you are uncomfortable posting anything here. Also, I suggest you visit the Vision and Spex site and sign up for that. Education and learning about vision and how it works will be helpful to you. There is no magic to this process.

So first off, thanks to Cactus Jack for helping me out getting onto this website!

I never knew that there were people like me, fascinated and interest in myopia and glasses the way I am. I found this site and was delighted to see that this exists

A little background on me....I'm a 17 year old who currently has no myopia at all. (And I want to change this!) I have some -1.25 and -2 tucked away at home and only (and rarely) wear them when no one else is home. The main obstacle here is my parents and would be a weird convo to have.

Anyway the reason I'm posting here is I was wondering if there are ways in which I can in fact induce myopia. I have access to websites that I can purchase glasses on, but other than that I'm at a loss. I don't know here to start.... Thanks


CJB 05 Apr 2016, 15:43

Cactus Jack

I will be going to university next year, and I will live at home for the first semester, and reevaluate the second. I think the middle of May would be an appropriate time for the trial. I have a question, in August when I go to my normal eye doctor will I have to tell them I got glasses, or just pretend to not have any?

Cactus Jack 04 Apr 2016, 21:47


It has been a busy and hectic several days where I was going from about 6 in the morning until midnight. Unfortunately, some of my responses have been very terse.

Yes, at some point you will have to get your parents involved. That time is when you are pretty sure that you will actually get a prescription for glasses, after you have a successful "trial" exam or two. The way you do it is to begin displaying some of the symptoms of Myopia around your parents. Ideally, by then you will not be faking it and actually have a bit of myopia.

Some of the symptoms are:

Having difficulty reading the menu board in a fast food place.

Wanting to sit closer to the screen at the cinema

Squinting to help you read distant signs or small text on the TV,

Having difficulty recognizing friends across the street

Casually asking if your annual eye exam has been scheduled yet - That should beg the question, Why? Answer, you noticed that some of the street signs seem hard to read until you are pretty close, particularly at night.

Asking the the teachers if you could sit closer to the board

Mentioning to you parents that one of your classmates (not Scott) mentioned that they though I ought to get an eye exam when I asked if he would lend me his notes.

You get the idea.

Hopefully you will get an "Official" prescription and some officially sanctioned glasses. Once you start wearing glasses full time. You can do almost anything you want to as long as you keep the same or very similar frames.

There are some things you can do in an eye exam to get a slightly stronger prescription, but that can wait until you are pretty sure you are ready for an exam. It is pretty easy, but not obvious. It involves some of the principles of optical physics.

It would be nice if your first official prescription was Sphere in the -0.75 to -1.00 range with maybe a bit of Cylinder thrown in for good measure.

Will you be going to University while living ant home or in another city? Once you start in University, the reading load is notorious for causing increases in Myopia and sometimes the need for Bifocals.


CJB 04 Apr 2016, 20:33

Cactus Jack

At some point my parents would have to know, so I can wear glasses infront of them. When do you think the correct time is? I realize you are a busy man, so I would like to say thank you so much for always clearing up time to respond to me.

Cactus Jack 04 Apr 2016, 13:34


I will give you a better answer after I get back form an errand, but you don't need parental permission to get an eye exam. All you need to be able to do is pay the exam fee. A typical eye exam, without dilation, does not really involve much more than looking through some trial lenses of different powers. Fundamentally, what you wind up which is a piece of paper with a prescription on it. Some places will try to sell you some glasses, but you don't have to buy from them. By law they cannot refuse to give you your prescription because that is what you paid for.

More later. It really is not difficult.


CJB 03 Apr 2016, 23:07

Cactus Jack

I like the idea of a practice run before going to my normal doctor in August. I think I would really like to do that. How do I exactly accomplish this, though? Can a 17 year old schedual themseleves an appointmnet and go to it parentless? Or do I need to involve my parents? If I need to include my parents should I be upfront and tell them I would like to get my eyes checked because I am having trouble seeing? Or do I let them notice I am struggling and get them to make me an appointment? If it is the second how should I react when they say something about me struggling to see? Relieved? Defensive? Surprised? Mad? Happy? Sad? Or just unbothered? At thr appointment is there any way I can make sure I will get out of there with strongest possible glasses that are still reasonable? Are there tips and tricks I need to know/practice? What, if any specific symptoms should I complain about? Should I behsve a certain wsy at the appointment?

I think this is it, I want to give this whole thing a go. Maybe by the end of April, or begining of May. Hopefully vy having this run I can get a nice (strong(er)) pair of prescription glasses by August.

Also, once I get my own glasses (he says so hopefully, again) how do I insure I keep getting stronger and stronger glasses every time? Is that when I should start stacking contacts with glasses for more strength? Will this be where I get fit for contacts? I want too keep gettibg as strong glasses as I can without being obvious to what I am doing for as long as I can worsen my vision. I am 17, and I hear vision stops worsening in the mid twenties, so I have less than trnbyear to work on my dream. Lucky people who have already had hlasses forever. Lucky Scott. Talking about Scott he also vannot wait until I get my own glasses so we can both wear our glasses anywhere and everywhere together. He thinks we should get matching frames.

Thank you so much for all your help so far, you have been amazing, and I cannot thank you enough, but this is far from over, and I will keep thanking you the whole way because you are heloing a "kid" with his dream. I want to do this right and I can't do it without your help. Thanks for being such an awesome mentor!!! So sorry for the stack of questions. When I get excited I babble on and on (or in this case type on and on) without any fikter ti helo me stop the unnecessary/boring stuff. If you are still reading I am so sortu for this blabfest. I will stop myself now. Stopping. Have a great day, and once again thank you for everything! Have a great day or night! I am not going to proof read because if I do I will surely add two new paragraphs because I am so excited, so sorry for all the mistakes.

The difference is microscopic. Normally, glasses are prescribed in 0.25 diopter increments. In VERY rare instances an ECP will prescribe 1/8 diopter, but I think that borders on braggadocio. Even the vision of a person with "perfect" vision and health will experience very tiny refractive variations through out the day.

It is also rare for a person to have exactly the same prescription in each eye. Your eyes are really two independent body structures and while the body has bilateral symmetry it is very likely that your arms are not EXACTLY the same length and it is likely that your two feet are not the EXACT same size. You recently provided Scott's most recent prescription and there was a difference between his two eyes that did not exist in the glasses you have. Also, remember that Sphere and Cylinder & Axis, together, correct two completely different things and those things are independent of each other Sphere corrects Myopia, Hyperopia, and Presbyopia. Cylinder and Axis always go together (you can't have one without the other) and correct Astigmatism.

You are making excellent progress. In fact, I believe you are doing much better than I would have expected. The important thing now is to just keep on keeping on and if possible go to a slightly stronger prescription. Maybe something like -3.00 or -3.50, hopefully without any Astigmatism correction. The reason I emphasize that you don't want any Astigmatism correction is that we don't know if you have any Astigmatism, based on your exams, I suspect that you don't have any Astigmatism or very little. If you try to wear glasses with Astigmatism correction that you do not need, your brain will try to compensate for it, but it has no way to do it. That leads to headaches and fatigue. If you read back in some of our Inducing Myopia posts, you may notice that we emphasize that you should NEVER try to adjust your Cylinder and Axis correction, but copy it exactly in your new glasses prescription with some Sphere over correction. As you have noticed, you CAN, within reason, compensate for more MINUS than you need, but you CANNOT compensate for incorrect Astigmatism correction. That is why you should NEVER buy glasses for Inducing Myopia or doing GOC that were made for someone else.

As far as preparations for an eye exam, remember as Shakespeare said in "As You Like It" " All the world's a stage etc." and you need to play the role of a newly discovered Myope. We will teach you your role and how to play the part.

You could actually get a "trial" exam now if you want, but you need to NOT go to the same ECP you went to last time. You want to save that ECP until you KNOW that it is very likely that there will be confirmation that you need glasses. Consider that Eye Exam as a rehearsal for the actual performance. The key there is the symptoms you report and your responses during the exam.


P.S. it would be very helpful if I had a bit more information about you and where you live that you may not wish to post here. If you want to chat about this privately, please contact me at

CJB 03 Apr 2016, 15:24

Also, based on what Svensot said should I be worried that my eyes are ptobably not the same?

CJB 03 Apr 2016, 15:13

Cactus Jack,

Sorry for not knowing about the camera stuff. I would love to learn more about the stuff you think I should know before my appointment. I want it to go perfectly, and I do not want it wasted, aif I go, I want to come out with my very own first pair of glasses.

Likelenses 01 Apr 2016, 21:23

Cactus Jack

CJB could also wear the Rx glasses several hours before,and just prior to the exam,and then remove them and just wear sun glasses in to the appointment. That could be his explanation for the red marks.

Cactus Jack 01 Apr 2016, 20:32


The reason I asked about about photography, is that it would save some time if you were familiar with f stops and Depth of Field effects of small lens openings. Depth of Field means the Range of Useful Focus. High end lenses usually have indicators to give the photographer an idea of the range of useful focus. By adjusting the f stop, you get a graphic indication of how bright light causes your pupils to contract. If you don't have much Myopia, you notice that you see much better in bright conditions than you do at night. Ideally, eye exams or even our simple test should be done in fairly low light conditions so your pupils will open up and any refractive error will have a more pronounced effect.

The reason I asked about the frames and if they were leaving a mark on your nose, is that is a pretty good clue that you have been wearing glasses. If they did leave a mark, you would need to stop wearing the glasses for a longer period before a "first" eye exam. The will need to be a little deceptive if you want to get some glasses and the examiner needs to be thinking myopia and minus first glasses.

The more you understand about this stuff, the better job you can do playing the part of a new Myope.


svensont 01 Apr 2016, 11:30


It looks like your left eye is now -0.41D and your right eye -0.44D. Without Scott's glasses your vision should be blurry beyond about 7ft.

You are making a really good progress

CJB 01 Apr 2016, 09:29

Cactus Jack,


1. Both of Scott's parents are nearsighted, and one wears bifocals now.

2. My phone's is the only camera I have used in a really long time, so I would have to say no.

3. Scott is 18 now, and sorry but he has had way too many glasses over the years to remember when he had these exactly, but he thinks it was 10.

4. They are those small rectangular plastic ones, without nose pads, and they do not leave any marks, except behind my ears, because they are a little tight width wise, but my hair covers the marks, so no one sees them.

Also, I did the test again:

Left eye I got: 21 and 3/16 of an inch, 20 and 13/16 of an inch, 20 and 7/8 of an inch, 20 and 1/2 of an inch, and 20 and 5/8 of an inch.

Right eye I got: 20 and 1/2 of an inch, 20 and 3/16 of an inch, 20 and 3/8 of an inch, 20 and 5/16 of an inch, and 20 and 1/8 of an inch.


Thank you for the suggestion, but there is not one around me.

Likelenses 31 Mar 2016, 19:42


If you decide to get an eye exam on your own,and if you live in the U.S.,look and see if there is an America's Best optical near you.

For $ 69.95 you get a free exam,and two pair of decent quality glasses.

It would be helpful to tell the doctor that you are having trouble seeing clearly at night,especially when driving.

Cactus Jack 31 Mar 2016, 19:21


Excellent progress. When you focus at about 12 inches with Scott's -2.25 glasses you are providing about +5.50 diopters of Accommodation. About 2 weeks ago you could only supply +4.25 of Accommodation. To be able to wear Scott's current glasses you would need about +9.50 of accommodation. Remember, this is not much different than going to the gym and lifting weights. You are strengthening your Ciliary Muscles. Could you ultimately wear glasses with significant (-)? Maybe. But probably not as strong as Scott's current glasses. It depends on your genes. Scott may have a strong genetic propensity for Myopia. Do either of his parents wear Minus glasses?

After you have been wearing Scott's -2.25 glasses for an extended period, consider doing the distance test again without Scotts glasses, but with the +1.50 readers.

The key clue that it is time to start thinking about an eye exam is when distant signs, the white board in class, and the menu board in a fast food place is beginning to look a little fuzzy. Particularly in low light conditions.

Have you ever done any Photography with a high end camera that has a lens setting for adjusting the f stop?

You want to be sure that you are definitely having some distance vision problems without glasses before you start reporting any symptoms. If you don't actually get a prescription at the exam, you will have blown your chance for 6 months to a year.

You might ask Scott if he has any glasses that are a little stronger than these.

May I ask Scott's age now and how old he was when he wore the -2.25 glasses?

If you want to get an Eye Exam on your own, for cash, as an experiment, you can. You don't need anyone's permission. We can tell you what to say and what symptoms to report. The key thing is that you want to use a large optical chain that is not too close to where you will go for your exam in August. We need to talk about that, maybe in private.

A few more questions, for today. What is the frame style of Scott's glasses you are wearing. Plastic or Metal? Do they have Nose Pads? After you have been wearing them for a while, do they leave any marks on your nose?


CJB 31 Mar 2016, 16:07

Hey guys,

Just felt like posting an update. I have continued wearing Scott's glasses as much as possible, and I think it is really working, and I am getting used to my visiin with the glasses. Now with Scott's glasses on I can read about a foot away. It is a little dificult still, but not imposible. More than abything else, I truely feel like a glasses guy now from wearing Scott's glasses so much. I saw an old friend I had not seen in about 2 years last week, and she even complemented my new look by saying I looked great in glasses, and how my face was made to have glasses on. I really cannot wait to get my own glasses. Also, I finally convinced Scott ti let me try on his current pair of glasses, and may I say WOW if only I could need glasses like those. I loved the way they felt on my nose. They were the perfect weight. They did however hurt my eyes even looking tgrough tgem fir a second, and I could not see anything. I only dream of wearing glasses like those one day. Do you guys think it is possible? Lastly, for now, I was winderibg when and if I should start acting like I am having troubke seeing infront of my parents, or should I just act surprised when I get glasses (he says filled with hope and optimism)?

Cactus Jack 29 Mar 2016, 17:16

Myopic Jack,

There are two kinds of Myopia. Axial or True Myopia is caused by the eyeball growing too long for the eye's lens system. True Myopia has a strong genetic component and usually by the mid-20s your genes will not let the eyeball grow, no matter how hard you try.

However, the other type of Myopia, called Pseudo or False Myopia, is caused by the Crystalline Lenses and Ciliary Muscles. Pseudo Myopia and Latent Hyperopia are actually the same things, but just on different sides of 0.00. You might be able to induce some Pseudo Myopia, but the older you get, the harder it is to do because of Presbyopia. BYW, it does not matter which type of Myopia you have, the solution is the same for both.

The main point is that if you want to try, you have to get started ASAP, but you need to understand that there are no guarantees and if you do anything, it won't be much. GOC may be a better option for you. Age can be a factor but, you need to be able to wear contact lenses.

May I as a few questions?

1. What is your current COMPLETE prescription?

2. Have you ever worn Contact Lenses?

3. Where do you live?


Myopic Jack 29 Mar 2016, 13:00


to what age do you think, it is possible to increase myopia.

Still in your mid-40´s? Any chance?

Xbone 25 Mar 2016, 09:02


Can't support the "driving" part. "I don't feel in any sort of danger" is what drunk drivers say.

Ben 24 Mar 2016, 20:03

Hello everyone, it has been awhile since I have checked in.

I have ran out of my -10 contacts so I decided to move up to -12 since I felt I was accommodating quite well with the -10s.

They arrived today, and I am back to having some trouble with reading close up. I can read my computer just fine, however, reading my phone less than a foot away is a struggle.

My distance vision is fine with the -12s, especially during the day. Driving at night is a bit harder with the lights of the other cars, but it is definitely doable and I don't feel in any sort of danger while driving.

I will try to update more often, as I have been very infrequent with my updates, even though I do read this site daily.

Soundmanpt 22 Mar 2016, 10:06


How are you doing with your glasses? You seemed to be doing just fine wearing them. Are you feeling more comfortable wearing glasses now? Are you doing any better with being able to wear your glasses when driving at night?

til 18 Mar 2016, 15:45

The overcorrected night driving thing is still a mystery to be solved in my opinion. Going by personal experience the lens coating influences the overall vision quality but even with high quality coating the problem with oncoming car lights remains. You just seem to get star like reflections from light sources. Diopters and the accustomation of the brain seem to play a part in this. I'm emmetropic and have perfect (normal) night vision with up to - 3.5, anything above is not safe.

Maybe some of our high experienced members can shed some light on this ;-)

Soundmanpt 18 Mar 2016, 15:00


Based on what you say it seems like your going to be just fine wearing your -1.25 glasses. You've only had your glasses a few days and your eyes seem to be adjusting to them without any problems. Your distance vision I know has to be really extremely sharp and clear. I was more concerned with how well you could manage seeing things close up such as a newspaper or book for long periods of time if you had to. So far you seem okay with that as well. That only leaves the problem with wearing glasses and driving at night to solve. You didn't say but I assume your glasses are fine with driving during the day? Actually "Antonio" maybe right about not having an AR coating (anti-reflective) on your lenses. You may have missed seeing the option for that coating when you placed your order for your glasses. I know of several friends that went on their own and ordered glasses from Zenni and when I asked them if they remembered to get the AR coating they had no idea what I was even talking about. The coating only costs $5.00 but it is worth every penny. I think your glasses are fine and not too strong but your not really used to wearing glasses when your driving and at night it is even harder. What your seeing is the glare from overhead street lights and oncoming car headlights hitting your lenses and that is what is bothering your eyes. I think the more you continue wearing your glasses you will not notice the glare as much as you do now. One thing you did find out when you were attempting to drive at night with your glasses on is that your eyes were so adjusted to your glasses that when you took your glasses off things were blurry enough that you had to wait a minute or so for your eyes to refocus in order to see to drive. This should be encouraging to you since that is what your hoping will happen, but of course you want that blur to stay when you take your glasses off. But if nothing else now you know that even if you it is too late for you to induce any real myopia you can still wear minus glasses without any problem. Your already learning about how much blur your glasses causes your eyes when you take them off so all you would ever need to do is squint a little and claim you see something without your glasses even if you can see it perfectly. Remember if they try your glasses they will certainly notice that they are very real glasses and should have no reason to ever question your need for glasses.

So I am sure you never bothered getting glasses with your real +.25 prescription and these then are your first glasses. So what kind of comments have you been getting form everyone. Were you nervous about wearing glasses that first day or so?

antonio 18 Mar 2016, 10:10

Hi Janie,

interesting experiment you do.

I think for driving you need new lenses with anti-reflective coating in your glasses. That could help a bit.

The fact that your eyes needed some minutes already to get back to normal view means they are really adapting to your new glasses.

If you proceed wearing them so often, might happen that in a few weeks or even months your eyes don´t go back to normal sight without them, but remain kind of nearsighted without your glasses giving you a blurry sight which is bad to drive with especially at night.

Probably your eyes won´t need so soon -1,25, i.e. your full glasses strength to see, but they might start to need the power of -0,5 or -0,75 of corrective lenses in some weeks or months to make you see clearly again.

So think good about wearing them or not in advance,

if you like we can chat on lenschat,

best regards, Antonio

Janie 18 Mar 2016, 02:48

Hi all,

Thanks for your comments.

For these few days i wore the glasses. Now feels like its normal. But at night i couldnt drive with glasses because with lights i couldnt see any thing. After i take them off while driving, stil i had to wait more than a minute to able to see normal again.


CJB 17 Mar 2016, 15:39


I wear Scott's glasses about 75-80% of the time everyday.

CJB 17 Mar 2016, 15:38

Scott's current prescription is riggt eye -11.25, left eye -10.75 and right eye astigmatism -1.5 and left eye astigmatism -1.25.

Soundmanpt 16 Mar 2016, 13:57


I agree with "Likelenses" you're being a little too aggressive by getting glasses that are -1.25 because they are just a little too strong for your eyes. Actually since your own actual vision is +.25 that means that what your doing is the same as trying to wear -1.50 glasses. Really if you asked I also would have suggested that you start off with -.75 glasses since that would be in effect the same as wearing -1.00 glasses to your eyes. Now it seems your finding it rather difficult to wear your glasses full time which is critical if you have any hope of inducing any myopia at all. Not at all surprising that they are feeling much too strong when your doing close work and you must be straining even to see with the for distance. You really need to go back in an order the exact same glasses as you got from Zenni but with -.75 lenses. They will feel much better to your eyes and you should be able to see much better with the weaker lenses for driving and close work. The last thing we would want is for you to have an accident because your glasses are too strong and you weren't seeing very well. After a few weeks or so your eyes should be adjusted to your glasses and then you can start trying to wear your -1.25 glasses that you have without anyone noticing your wearing different glasses. Hard to say if will be able to induce any myopia or not but your eyes should at least be able to tolerate your -1.25 glasses and allow you to wear them very comfortably even if your actual vision never changes. But for now the main thing is for you get glasses that you can wear comfortably full time and make a point to put your glasses on as soon as you open your eyes each day and don't take them off until you are turning the lights out for bed that night.

Cactus Jack 16 Mar 2016, 08:30


You are making good progress and you need to keep up your efforts.

You can do the simple math to measure your progress as well as we can. When you wear the +1.50 reading glasses, they have the same optical effect as if you had -1.50 of myopia. The whole purpose of he +1.50 glasses is to get the distances into an easy to measure, range. If you did not use the +1.50 glasses, a small amount of myopia, say -0.25 would cause blurriness beyond about 13 feet which is not a practical distance for the test.

The math is easy 39.37 (1 meter)/1.50 = ~26.25 inches. When you did the test you got an average of ~22.5 inches. 39.37/22.5 = ~1.75 which means that your vision with the +1.50 glasses was as if you were wearing +1.75 glasses or +0.25 diopters more than you were wearing. Remember that people with myopia effectively have "built in" reading (plus) glasses. That in turn means that when you did the test you had created -0.25 diopters of myopia.

One of the things that makes understanding this process, difficult is realizing that glasses or contact lenses neutralize or cancel out, refractive errors.

You asked about symptoms. When you go for an exam, you should tell the examiner that you seem to be having some problems seeing the board clearly and that when you drive, distant road signs don't seem very clear, particularly at night. I suspect, by August you will have created more than -0.25.

It is good to know that you have a selection of Optometrists available. That will come in handy later. If convenient, you might inquire about the fee for an exam for glasses.

Just out of curiosity, what is Scott's present prescription.


svensont 16 Mar 2016, 01:06


you are making a good progress,

at the beginning the distance was about 26.5-27 inches, now it's 22-23, so it's like -0.25D of myopia.

How much time in % do you wear Scott's glasses?

CJB 15 Mar 2016, 23:11

The drivers test did require an vision test, and I took it withiut glasses because I took the test at the begining of January(before I started tryibg ti induce some myopia), but never picked up/ got my license made until Monday. Since I am not precribed glasses I did not wear them to take my picture, or to the tag agency in general.

Likelenses 15 Mar 2016, 21:57


Did you drivers test include a vision test?

Did you take the test with glasses on?

CJB 15 Mar 2016, 21:11

I do have my drivers license, in fact I just got it on Monday. I did the test, and the numbers I got for my left eye were- 22 and 3/4 of an inch, 22 and 7/16 of an inch, 23 and 1/8 of an inch, 22 and 7/8 of an inch and 23 and 5/16 of an inch. For my right eye the numbers were- 22 and 3/8 of an inch, 22 and 11/16 of an inch, 21 and 15/16 of an inch, 22 and 1/8 of an inch and 22 and 13/16 of an inch. What does this mean? Is the process working( do you think I have induced some myopia)? If so, how much so far(If I were to get an eye exam right now, would I get glasses, and what do you think their power would be)?

I have looked up six other optometrists, and they all have appointmnets available the after the 16th of August, and before I head off to school in the fall. I called as an unknown number, and used a fake name when asking about dates because I wanted to run this by you first. My appointment has to be in or after tye 16th of August, since that is when I had my last eye ecam last year and I only get one free one per year through the insureance company.

What symptoms are you talking about?

Likelenses 15 Mar 2016, 20:11


I think that you can induce some myopia,even at the age of 27.

You may be better off starting off with -.75,but it is worth a try with the -1.25.

Beside wearing the glasses for every waking hour,I suggest that you hold any reading material to include the computer as close as you can tolerate.Try to do at least an hour of close reading continuously with out taking a break,or looking away. every day.Also get in the habit of squinting when looking at distant objects.

If you can do this I think that you could be a girl with -2.00,to -3.00,in about a year.

Janie 15 Mar 2016, 19:07


This is first post from me in here ☺

Im 27 year old girl who has +0.25 in both eyes.

If i tell you the truth, i don't like to wear + glasses because of their look.

But i like minus glasses very much. I think im very lucky if i can wear minus glasses whole of my life.

So i took below decision to get miopia. Please advice me what will be the out come of the below.

I ordered -1.25 glases from zenni and i recieved 2 days ago. I wore most of the time of the day . Begning i had little dificult to work in computer. But how ever i wore it with eye strain. Night i went to a party with them. It was little dificult to drive and cope up with lights. But i didnt take them off until i go to bed.

So will i get miopia by doing this? Plese advice . If not, please tell me how to achieve this. Thank you

Cactus Jack 13 Mar 2016, 16:19


It sounds like you are making good progress in strengthening your Ciliary Muscles. To be able to focus comfortably in the 19 to 21 inch range, requires about +2.00 diopters on top of the +2.25 required to compensate for Scott's -2.25 glasses, for a total of +4.25. It was not all that long ago that you were having a bit of a struggle to see distance objects clearly with Scott's glasses.

You have done amazingly well, considering the limited resources at your disposal.

As a short term goal, I would suggest that you should try to work reading with the -2.25 glasses in to about 13 inches. It won't happen suddenly and it will probably be easier when you are well rested.

If you are in a situation where you need to do some close work, but cannot wear Scott's glasses, try to hold the book as close as you reasonably can. As an FYI, +4.25 of accommodation is like focusing at about 9 inches without glasses.

When it is convenient, I would suggest that you do the test wearing ONLY the +1.50 glasses and measure the distance where the text becomes slightly fuzzy. Ideally, you will be able to do this test after a long period of reading with the -2.25 glasses. Initially, you may be disappointed with the results. Vision with +1.50 glasses, for a person who has 0.00 refractive error, should just become fuzzy at a distance of about 26 inches. If you measure less than 26 inches, you are having some success, but don't sweat it if you can't tell much difference yet. This is not a sudden process.

I would also suggest that you start saving up a little money for an eye exam by a DIFFERENT ECP than you typically visit. I will tell you what symptoms you have before your visit to any ECP.

Another question, do you have a Driver's License yet?


CJB 13 Mar 2016, 11:54

Cactus Jack

sorry it has been a while. I was just so busy with midterms, but I did a measurement and I can comfortably read about 19 inches away with Scott's glasses on. I did 10 measurements going away from my face until I could read the page without struggle, and the average distance was 21.4 inches. Is this good, as in where I should be now, or not?

CJB 03 Mar 2016, 14:03

Cactus Jack

I will post on here later with measurements. As far as eye doctors appointment, I already have one scheduled for the middle of August. I have always gone in around that tine every year, and after the appointment they ask us to book our next appointment. Right now my appointment is set for August 19th. I woulf appreviate talking about what do before during and after ny appoinent though.

Cactus Jack 02 Mar 2016, 19:57


I have been wondering about how you were doing also. Have you been noticing that it is easier to focus closer with Scott's glasses? Ideally, what is occurring is that you are strengthening your Ciliary Muscles, which makes it easier to add the extra PLUS you need to compensate for the -2.25 for distance AND add the extra PLUS beyond that for close focusing.

If possible, please keep us informed with some numbers such as the distance you can comfortably (relative term) read with the -2.25s. Ideally, it should be gradually coming down.

Please do not schedule an eye exam until we have talked about what you will need to do before and during the exam.


CJB 02 Mar 2016, 17:32

Its great. I have been wearing glasses pretty much nonstop. I only take them off at home when i am not in my room and my parents are home. Hopefylly everthing works out great, and by the time I have ny annual eye doctor's appointment I will need glasses.

svensont 02 Mar 2016, 09:11


How is your progress?

Cactus Jack 28 Feb 2016, 08:55


The test is pretty easy. It is a practical application of the basic laws of optics codified by Sir Isaac Newton about 300 years ago.

The idea is to use known power, sphere only, PLUS glasses to simulate myopia. Measure the apparent myopia and then compare it to what should have been created by the PLUS glasses. The +1.00 readers are not strong enough for the test, but the +2.50 readers should work.

You will need a book or newspaper with normal sized type and a tape measure, yard stick, or meter stick, in addition to the +2.50 readers.

1. Good, but not super bright conditions, put on the +2.50 readers (only).

2. hold the book or newspaper close enough for the text to be sharp and clear.

3. Gradually move the text away from you until the smallest text just begins to get fuzzy.

4. Measure and note the distance from you eyes to the text. Try to be as accurate as you can. Also, try to keep your eyes relaxed during the test (IOW, don't try to help).

5. Do this 3 times and average the distance.

6. Tell me the results. and I will do the calculations

The calculations are really easy and you will be able to do the test anytime you want to measure your progress.

Answers to your questions.

1. At 31, you should have quite a bit of accommodation available. It depends on how well your Ciliary Muscles are conditioned. Some years ago, I worked with an EXTREMELY motivated, mid 20s, client who was moderately myopic (-4.00) and badly needed to be at least -5.50 with strong dilation. He was able to work himself up to wearing -20.00 glasses while studying. Because his Axial myopia was -4.00 and Vertex Distance effect of -20.00 glasses his Pseudo Myopia was approximately -12.00. He was able to retain enough Pseudo Myopia to fail the eye test with about -6.00.

2. It is likely that if you work your way up to -3 or -4 you will be able to sustain it for quite some time.

3. Ultimately, you will need bifocals or even trifocals for closer work, probably sooner than is typical, because you have used up much of your accommodation range compensating for the MINUS glasses.

4. Can't tell for sure, but it is likely that two thing have happened. You have strengthened your Ciliary Muscles and you may have increased the residual PLUS being supplied by your Ciliary Muscles. You may have induced a little Pseudo Myopia. Hopefully the test will confirm that.

May I ask your occupation and how much close work you do with a computer or reading?

Also, I would like to ask you to contact me privately at

The test is pretty easy. It is a practical application of the basic laws of optics codified by Sir Isaac Newton about 300 years ago.

The idea is to use known power, sphere only, PLUS glasses to simulate myopia. Measure the apparent myopia and then compare it to what should have been created by the PLUS glasses. The +1.00 readers are not strong enough for the test, but the +2.50 readers should work.

You will need a book or newspaper with normal sized type and a tape measure, yard stick, or meter stick, in addition to the +2.50 readers.

1. Good, but not super bright conditions, put on the +2.50 readers (only).

2. hold the book or newspaper close enough for the text to be sharp and clear.

3. Gradually move the text away from you until the smallest text just begins to get fuzzy.

4. Measure and note the distance from you eyes to the text. Try to be as accurate as you can. Also, try to keep your eyes relaxed during the test (IOW, don't try to help).

5. Do this 3 times and average the distance.

6. Tell me the results. and I will do the calculations

The calculations are really easy and you will be able to do the test anytime you want to measure your progress.

Answers to your questions.

I'm not familiar with this test but I'd like to try it. I have a couple of old pairs of reading glasses lying around. One pair of +1.0 and a pair of +2.5.

As far as wearing minus lenses go I see myself wearing -3.0. I probably will not want to go any higher than this and I'm not sure my eyes will want to let me. I have a couple of questions

1. If I am able to induce some pseudomyopia at what strength might this be?

2. Will I be able to sustain it?

3. What will happen when I become a presbyope, will I just need to take my glasses off to read or will I likely still need plus lenses?

4. Why do you think my vision has improved when my accommodation is relaxed after wearing the minus lenses?

Cactus Jack 27 Feb 2016, 21:32


I agree that it is doubtful that you can develop any Axial or True Myopia. I strongly suggest that your genes simply won't let that happen. However, you may be able to develop some Pseudo or False Myopia.

Latent Hyperopia and Pseudo Myopia are actually the same thing on the two sides of 0.00. So the fact that you developed some Latent Hyperopia is a good thing. The usual cause of Latent Hyperopia is the Ciliary Muscles getting so used to squeezing your Crystalline lenses to add some extra PLUS to correct Hyperopia that they have difficulty relaxing for distance. By wearing the -1.50 contact lenses, you are forcing your Ciliary Muscles and Crystalline Lenses to produce an extra +2.25 for distance and even more PLUS for close focusing. The trick is to keep up the pressure and gradually increase the MINUS in either contacts or glasses.

Have you noticed the simple eye test, that you can do with some PLUS reading glasses, a book or newspaper, and a tape measure, that I have posted here? If you would like to try it, we may need to modify the test slightly because of your hyperopia.

If you work at it, you may be able to maintain significant Myopia long after Presbyopia sets in. While Pseudo Myopia is considered temporary, as your Crystalline Lenses get stiffer, it slows down the relaxation process.

Good afternoon from Scotland. I've just discovered I'm a latent hyperope however like others long for the look of the minus lens on glasses.

This might seem a little robotic but I'm going to list the following information in separate lines for easy and quick understanding.

I am 31 years old.

I am a latent hyperope 0.75 in each eye.

No astigmatism found in exam (not sure if it was tested for)

I have conscious control of ciliary muscles. (Can make everything blur at will)

I have better than 20/20 vision - somewhere between 20/10 and 20/15.

I am currently wearing -1.50 in each eye with contact lenses.

I have ordered -1.75 glasses from zenni but I'm already sure I could go stronger than this.

My understanding is that I will probably never become myopic and that even if I wear strong minus lenses eventually I'll have to take them off due to presbyopia developing. I have noticed that in the short few weeks that I have been wearing the -1.5 contacts that when I take them off and relax my ciliary muscles that the blur I usually experience is much less than before. To give you an idea of this - before I started wearing the minus lenses a +2.0 pair of readers were needed to correct the lack of accommodation. Now I can make out the numbers on my wrist watch so a definite improvement.

What do you think?

Cactus Jack 27 Feb 2016, 06:28


I don't know how it is in Russia, but there is a very old saying here "Men seldom make passes at girls who wear glasses" .We know today ,that is not true, because carefully chosen glasses can often make a woman more attractive. we also know that some men are attracted to girls who wear glasses, just as there are girls who are attracted to men wearing glasses.

I am not trying to pry into your love life, but I need to know a bit more about you and your wife to make suggestions.

1. How long had you known your wife before you got married?

2. Had you ever seen her wearing glasses before or when you were dating?

3. When she was wearing her glasses, did you ever complement her on how beautiful she looked when she was wearing them?

Both men and women want to be attractive to their mates, but they often think that what they like is also what their mate likes.

The important thing is to not try to rush anything. It is usually non-productive so you must be patient.

May I ask your occupation and educational background?

Have you studied English or are you using a translator program?


Likelenses 26 Feb 2016, 17:40


Cactus Jack,and Soundmanpt are correct,you should not try to be forceful.

You could show her some nice frames at an online optical,and let her pick the ones she likes.Tell her how fantastic you think she would look in them,and then offer to buy them for her.Then you could order one in her prescription,and another of the same frame with an increase of perhaps an additional -1.00.

When they arrive give her the ones in her prescription,and a day or two later while out doing something distant viewing demanding,suggest she try the other pair on.She may just like the high definition,and use them more frequently.

In addition to Soundmanpt's suggestions,perhaps you could rearrange the distance from her favorite chair to the TV,and put a few lower wattage light bulbs in the rooms

Be loving,and gentle,and always tell her how great she looks when wearing her glasses.

Soundmanpt 26 Feb 2016, 15:14


What you don't seem to understand is that even increasing your wife's glasses by -.50 her eyes are going to notice the difference in her glasses being stronger. Also just as "Cactus Jack "has told already told you, her current prescription is already at the point where she really should be wearing her glasses full time now and she refuses. So making her glasses any stronger isn't likely going to do anything if she doesn't wear them. Right now you really just need to encourage her to start wearing her glasses more often. Maybe try and find things that she would need really good vision in order to do very well so she has to wear her glasses. Things like target shooting with a gun or bow and arrow.

Shaun 26 Feb 2016, 11:24

Please note that i dnt want to force her to wear glasses. Thats why im trying to increase her prescription gradualy and make her difficult to stay without glases. Now she is not wearing because she can handle that vision. I just want to make her vision bad so she will compel to wear glasses.

Thnk you

Shaun 26 Feb 2016, 11:19

Sory for the previous post. Actualy i didnt get your questin in the previous post. Sory again.

Im nt wearing glasses yet . But i was wearing -1.5 glasses for last 3 mnths trying to induce miopia and i think i need now real glases. I like the feeling of glasses. Thats why im tring to do this. Im 26 and my wife is 24. We married 2 mnths ago. I love her very much. I have a special feeling towards her when she is wearing glasses. Thats the reasn im doing this. By the im from russia.

I appreciate your feed back and advice.

Thank you

Cactus Jack 26 Feb 2016, 09:31


You didn't answer my questions. I don't ask questions because I like typing. I have a reason.

First, you need to understand what your wife's prescription means. I will use some approximations because even though your wife's prescription is not very high, she has enough astigmatism to be an important factor in her vision. When you combine the Sphere (first number) and the Cylinder (second number), her Visual Acuity without correction is about the same as needing -1.75 Sphere only glasses or contacts.

If you have reasonably good vision, you can simulate needing -1.75 glasses by trying on a pair of +1.75 reading glasses. That means that every thing is increasingly fuzzy beyond about 22 inches or 57 cm. However, because of her astigmatism and the Cylinder component in her glasses, her vision is messed up, at all distances, without her glasses.

What all that means is that she should be wearing glasses full time. She definitely SHOULD NOT drive without her glasses and because of the astigmatism, she oribably finds it uncomfortable to read without her glasses.

Something that adds complexity to the fundamental issues is that the eyes are merely biological cameras. Vision occurs in the brain using the input from the eyes. The brain can correct blurry images, IF it knows what something is supposed to look like. In fact, the brain can create images with your eyes closed. Ever had a dream?

It is a curious phenomenon that when a person puts on their glasses for the first time, they often feel like the glasses have made their vision worse. That happens because it takes the brain a while to stop correcting the blurry and possibly slightly distorted images it has been used to working with.

The point of all this is to help you understand that your wife really needs to be wearing glasses full time, but something is overriding that need. It is likely vanity, but it could be something else.

You could order her some glasses with a SLIGHT increase in Sphere, but if she won't wear her present glasses, what makes you think you could FORCE her to wear some glasses that are initially uncomfortable. I don't know where you live or your cultural background. If you live in the "western" world and you tried that with the average woman, you would find yourself in Divorce Court.

There are important psychological issues involved here that are much more important than a glasses prescription. A brute force approach typically WILL NOT WORK and it is deadly to try one.

A few more questions:

1. What is your age?

2. How long has you been married?

3. Any Children?

4. What is your occupation?

5. Do you need any vision correction?

6. If so, what is your prescription?


Shaun 26 Feb 2016, 07:32

How ever I want to see her wearing some thick glasses all the time. I need your advise to increase her prescription


Cactus Jack 26 Feb 2016, 00:33


How do you like being married to your present wife? would you like to stay that way?


Shaun 25 Feb 2016, 22:33

My wife is -1.25 -0.75 and -1.00 - 1.25. She is trying always not to wear glasses. But i want her to wear all the time. I want her to induce some aditionl power and want to make it very dificult to stay without glases. She is 24 years. So please give me a tolarable and unnoticable prescription to ordr her new glasses online which makes her fully dependant on glasses.

Thank you

Cactus Jack 24 Feb 2016, 19:14


I am deeply sorry to hear of the tragedy in your family. I understand how something like that can affect a family. We lost my younger sister to leukemia when she was 16. I was 22 and in the Army, fortunately stationed only about 25 miles from our family home. The trauma, stress, and costs were very hard on Mom and Dad, which they never fully recovered from and also very hard on my younger 7 YO at the time brother. He did not fully understand what was going on and I am convinced that it has affected him all his adult life.

I think you made the right decision about not ordering glasses or contacts yet. The glasses are easy to order and pretty inexpensive form Zenni, but for now, any professional exam would be a waste of money. I don't know what the going fee for a CL exam is where you live, but here in Houston, it is $70 or at least was a few years ago when I had my last one. Dry Eye problems make wearing contacts uncomfortable for me now.

Now that I understand your situation, I will be better able to offer economical solutions and possibly work arounds. Here is a potentially low cost suggestion if you have any "dollar" stores where you live. Some of them sell VERY low cost reading glasses. If you can, check them out. What you are looking for is reading glasses in the +1.00 or +1.25 range. With Scott's glasses and the +1.50s you have the effective power of -0.75. If you could find some cheap +1.00 readers, that would give you the equivalent of -1.25 if worn over Scotts glasses. +1.00 readers are usually very hard to find because most people who need OTC readers wait until their arm become too short to be able to read and they need readers that are stronger than +1.00. If they don'e sell, stores won't buy them and the manufacturers won't make them. (Econ 101). If you keep working at it, I suspect you will be able to read pretty comfortably with Scott's glasses, by the end of March.

I saw a piece in today's (Feb 24) Wall Street Journal that you might find interesting. You may be able to access it from the school library. It is the lead article in the Personal Journal section. It is entitled "Why Solve the Unsolvable?". It is about a course all freshman engineering students are required to take at Northwestern University. They particularly focus on tackling problems without clear solutions, mostly as related aids for handicapped people. The purpose is to teach Empathy, Creativity, Teamwork, Brainstorming, Risk-taking, Humility, and Resiliency to young people who have no experience with difficulty accomplishing a task or even failure. Let me know if you want to read it, but can't access it. We'll work something out.


CJB 24 Feb 2016, 17:15

Cactus Jack,

I do understand that this will take tine, and won't happen overnight. Also, I want you to know I do respect and try to implemnet what you say. The reason I went for Scott's old glasses instead of ordering -1 glasses was because I do not have the money to order glasses right now. My famiky is kinf of in a money hole right now. My brother had gotten into an awful accident, and passed away about five months ago. As it happened he was in tye process of getting his own insurance because he was too old for the kids insurance, so we are still paying off about a month and a half of hospital bills. I really wanted to start this process and not wait for the timing to be right in the sense that I would not feel bad using money for unessential stuff. The best way ti do it was with Scott's glasses. I have taken you advise though, and when I am in my room, or have the house to myself I wear the old reading glasses over Scott's.

I mentioned all this because I just hope you understand that I do greatly appreciate you helping me through this process, but I want you to also understand that I have constraints at the time. I do not try to or want to directly and/or deliberately want to not do something you tell me to do, but like with the -1 glasses and Scott's glasses sometimes I have to settle because I do still live at with my parents (not full freedom) and the my family is in the unfortunate finacial situation I mentioned above. Please bare with me, and know I am doing my best to listen and take your advise.


Cactus Jack 24 Feb 2016, 15:26


First of all, your academic accomplishments are excellent. I won't feel uncomfortable discussing technical issues. I would like to suggest this link. It is pretty good. I think it will help you understand the amazing structure of the eye. In many ways it is very similar to a modern Digital Camera with a multi element lens system.

In addition this biological camera is very adaptable as the eye changes size as a person grows from infancy to adulthood. The more we understand the actual process, the more amazing it is. It leads one to wonder at the cleverness.

You are trying to artificially induce some eyeball growth, providing your genes will let you. Frankly, that does not happen very fast. Even people with aggressive Progressive Myopia, the rate doesn't usually exceed 2 to 3 diopters per year, which translates to about 0.3 mm per diopter of distance change from the back of the Crystalline Lens to the Retina.

Right now, you are working an a must quicker effect using only your Ciliary Muscles and Crystalline Lenses. When you wear MINUS glasses you are exercising and strengthening your Ciliary Muscles when you compensate for the -2.25 as I have explained before. You are making progress using the tools you have. The technique is the same as used by a weight lifter at the gym. However, you need to remember that the effect is temporary.

Hopefully, you live in a large city with many Eye Care Professionals. In the process of getting glasses or contacts you need to be aware that you will often visit the ones you select ONLY ONE TIME. You don't want them to be able to check the results of your previous exam. Also, you will be more likely to get an "official" prescription from a large chain that is focused on selling glasses that from an independent ECP.

Please remember that we have been down this road before and know more about what can work and what definitely WILL NOT work. Having been a bright teen ager myself ( I graduated from High School when I was 16), I fully understand that you believe you have ALL the answers. The problem is that you don't know the questions, yet. I'm 78 and I understand that even at my age, I have heard a lot of the questions, but NOT ALL. It helps me keep an open mind. I suggest you make a conscious effort to open yours.

I sincerely believe you will be able to accomplish your goal, but it will not happen as fast as you want it to or will be as easy as you expect. I don't want you to get frustrated. You like puzzles and problem solving, but the solution to this one involves many factors you don't know about yet and are difficult to control. They are surmountable, but if you "paint yourself into a corner" the problem is harder to solve. Some of the problems involve Psychology and other peoples expectations and beliefs. In those instances, your wishes don't count for much and sometimes, you can't disclose them. Those elements are the hardest to deal with. The optics is the easy part.

Yesterday I tried using my laptop with just Scott's glasses on, it was not as bad as it was on friday when I had tried the same thing. I think I am finally getting used to wearing Scott's glasses. This morning I had to take off my glasses for the first time since friday morning, and it felt so weird not having glasses on. I now nore than ever feel like I am meant to wear glasses, I am optemistic that wearing Scott's glasses is going to do the magic. Things in the distance with Scott's glasses are almost perfect now, and tge medium distance is not that bad either, and reading small print on my phone is still pretty hard, but I have to admit it is better now than before. I think I am going try reading only with Scott's glasses from now on, and hopefully by Monday my vision with them on will be perfect at all distances.

CJB 23 Feb 2016, 00:53


I am actually a senior in high school, and I took chemistry my sophomore year, and it was okay, I feel like it may have been more interesting if ir were with another teacher because that teacher honestly hated me. As far as physics goes I took AP Physics 1 last year, and did not really enjoy it because my teacher was hardly present, so we always had subs which meant we had to teach ourselves. This year in AP Physics 2 with the same teacher I am actually really enjoying the class, and the topics much more than last year. I do believe we are supposed to go through waves and optics in April. I was aware of who sir Isaac Newton because I am in my second year of both calculus and physics. My calc teacher last year explained to us what you were talking about why Newton created calculus, so I did know.

Cactus Jack 22 Feb 2016, 10:14


Thank you. That helps me compose my answers in familiar terms. I am guessing your you are a Junior in High School. If you like Math, you should also consider some of the Sciences. Physics, and Chemistry, which I throughly enjoyed, were my favorites. I took Biology for one semester as an elective, but didn't much care for it, mostly because of the teacher.

There is a lot of emotion these days in trying to understand how things work. There are people and politicians trying to change some of the laws of Physics and Chemistry because it would be nice if they were different. Admittedly, we don't know all the laws, but those laws that have stood the test of time seem to work pretty well in practice.

You may have noticed that I frequently refer to Sir Isaac Newton and his discoveries about Optics. He is most famous for is laws of motion and discoveries about Gravity. Are you aware that he invented Calculus because he could not use common Math to explain Gravitational effects such as acceleration of objects dropped from a great height?

We live in a marvelous age. Many things that were first foretold by Math many years ago have been discovered to actually exist. The Higgs Boson and Gravity Waves predicted by Einstein have been recently detected. Many recent discoveries have no practical applications, today, but who knows what the future holds. Many things that we use today were "impossible" when I went to school.

As good example is data transmission rates. My first encounter with Computers was in 1975. Data Transmission rates over phone lines topped out at 110 bits per second or 10 characters per second. Today it is much, much higher. How that happened is an interesting story, but not appropriate here.

Please keep me informed about your progress.


CJB 21 Feb 2016, 23:45


Sorry I just noticed you asked me about my favorite subjects in school. Math has to be number 1, it always has been. I just love how every question is like a puzzel, and hiw you can always check your answer by working it backwards. Second would have to Government and Politics. I just find law so interesting, I could honestly just lose myself reading about government. Politics are super interesting and I love heating all these different views that have/had, and I could watch CNN all day.

CJB 21 Feb 2016, 20:18


Yes, I do mostly understand the optics begind what you are saying. Tomorrow morning may be the first time since Friday that I will have to actually take off Scott's glasses depending on if my parents or running early or late before school, and if they come into my room. I spent the weekend at Scott's because his parents were out of town, and since his sister and her boyfriend were in charge so our parentset me spend the weekend. So far the only time they have come off my face is when I wash my face, and even then I keep my eyes closed. Idealy I want to keep them on for a week from the moment I wake up to the moment I sleep so I can see if they have had any effect. Hopefully tomorrow I can get fit for contacts, and hopefully I can order them and get them by next week. Contacts will make this whole process so much easier. I love wearing Scott's glasses, but I just really want my own pair of glasses. My sister is taking her kids for their annual eye appointment tomorrow, and as sad as this is I am jealous of the. I wish I was my niece the one who already has glasses.

Cactus Jack 21 Feb 2016, 16:11


It would probably be very difficult or even impossible to Induce any Axial or True Myopia at your age. It is likely that your eyeball growth has stabilized by now. However, you may be able to induce some Pseudo or False Myopia. Axial Myopia is caused by eyeball growth beyond the optimum and is considered permanent. Pseudo Myopia is caused by the Ciliary Muscles having difficulty relaxing back to minimal PLUS power. Pseudo Myopia is considered temporary, but if you support it, it can last a very long time.

Even though Axial Myopia and Pseudo Myopia have different causes, the have the same effect. They both require MINUS glasses for correction.

May I ask a few questions?

1. Where do you live?

2. What is your occupation

3. What is your educational background regarding Math and Physics.

The above will help me phrase my suggestions and answers.

There are no guarantees, but if you want to try this, you need to start ASAP.

Fundamentally, your initial strategy is as I described for CJB below. You need to order some inexpensive -1.00 and -2.00 glasses from an online retailer such as Zenni Optical. Their website has gotten a bit more difficult to navigate recently, but it is doable. We can help you.


Cactus Jack 21 Feb 2016, 15:51


When you are wearing Scott's glasses AND the +1.50 readers, that is the optical equivalent of wearing -0.75 glasses. You should continue doing that as much as possible until you can read comfortably at 13 to 14 inches. That helps exercise your Ciliary Muscles. Occasionally, take off the readers and look at something across the room, then try using the computer at 26 to 30 inches with Scott's glasses alone. You should also occasionally try reading with just Scott's glasses. The object is to gradually strengthen your Ciliary Muscles.

Do you understand the Optical Principles behind what I am suggesting?

The key is repetitions of going from relaxed to stressed. I suspect that within 2 weeks you will be able to wear Scott's glasses for distance and using the computer without the +1.50s. I suspect that within a month you will be reading with Scott's glasses.


CJB 21 Feb 2016, 14:43


I jave always wanted gre3n eyes so that could just plain and simple be the story cause it is true, right? I tried what you suggested with the pair of of glasses I used ti so the initial test. Question, do I kèep wearing Scott's glasses while doing the teo glasses thing in my bedroon, or do I put a hold on wearing Scott's glasses all the time until after a while?

Today is my third day wesring his glasses, and I think I might finally slowly be adjusting. Things are not nearly as blurry as they were friday morining.


The glasses are black, smallish, and rectangular.

PatRick 21 Feb 2016, 11:41

I am in my early thirties and was wondering if you thought it was possible to induce any myopia at this point...i dont need any correction at this point and was wondering what a good starting prescription would be.

svensont 21 Feb 2016, 10:49


What style are the glasses you are wearing? Do you have a pic?

Continue posting about your progress ;)

Cactus Jack 20 Feb 2016, 21:31


Sorry about the typos and the over imaginative Spell Checker. It knows nothing about Hyperopic.

You have not mentioned any subjects in school. What are your favorites?


Cactus jack 20 Feb 2016, 21:27


The optical effect of wearing MINUS glasses is to make you "artificially" Hyperemic. At these powers, Vertex Distance effects are essentially nil. Therefore, the -2.25 glasses require that your Crystalline Lenses produce an additional +2.25 to compensate for the -2.25 for Distance and that results in a refractive error of 0.00 for focusing at INFINITY. For practical purposes, INFINITY is presumed to be 20 feet or 6 meters To focus closer than 20 feet the amount of extra PLUS you need is determined by Sir Isaac Newton's equation Lens Power = 1 meter / Focal Distance. To use English measures, to focus at 16 inches to read requires 39.37 inches / 16 inches = +2.46 or +2.50 or a total of +4.75 for you to focus to read. If you want to read your SmartPhone at 13 inches, your Ciliary Muscles and Crystalline Lenses will need to supply +2.25 and an additional +3.00 or a total of +5.25 to focus art 13 inches.

In the past, your Ciliary Muscles and Crystalline Lenses only had to supply either the +2.50 to read or +3.00 for your phone. You can certainly strengthen your Ciliary Muscles and probably be able to much more than the +4.75 to read with the -2.25 glasses, but it is very hard to start with that much extra.

Think of lifting weights at the gym. You don't start with heavy weights because you will probably strain your muscles. You start with light weights and work up. Thus the suggestion about starting with +1.00. BTW, one of my highly motivated clients, who was in his mid 20, was able to work up to wearing -20 glasses and doing University studying while wearing them. He started at about -4.00, so he had a head start. Because of Vertex Distance effects, he was wearing -12.00 over correction for distance and about -14.50 when reading.

There is a way to reduce the focusing load. You will have to do this in private, If you wear +1.25 readers over the -2.25 glasses, that will be the equivalent of -1.00 or +1.50 would be the equivalent of -0.75. If you could do that for a few days while focusing at varying distances, it will help strengthen you Ciliary Muscles without straining them. If you strain your Ciliary Muscles it will slow down the process. Just like straining your muscles at the gym.

The reason I asked your eye color is to perhaps help with a story. Blue eyes maybe. Or, can you think of any reason to do any kind of costume piece that would be enhanced with weird looking eyes. Halloween is a long time to wait. Maybe you could be planning to go to an Easter Party as a white bunny. They have red eyes. Or you have been offered a part in a school play, if you can look like the villain. The less far fetched the better. The problem with a school play is that the people at the optical shop might want to come see their handiwork.

I do hope you do nit think Iam trying to ignore youbin starting with Scott"s glasses instead of ordering a pair. This way just seemed more efficient for 5he tine being. They were free. And available tight them also if I get caught I do not have to lie I can say they are Scott's and I fo4git to give them back.

CJB 20 Feb 2016, 18:17

Sorry for the late response, I had a lot of personal stuff come up, and so I had no time yo get on here.


Yes, I has tried on his glasses before. I have been wearing them all the time since I got them from Scott before scho9l yesterday. Ti answer your question my eyes are greenish blue most of the time, but when I wear certain colors they are greyish blue. Everything id blurry with Scott's glasses on, but it is a functionable blur. I have noticed of alm the things reading is almost impossible, unless I move what I am reading far away from my face. It is hard to say, buy I do believe tight now is a little better than yesterday morning.

I would love your help in coming uo with a story for when I get fix3d for contacts.

You have perfect and even slightly better than perfect in one so trying to wear your bfs old glasses might be overly strong for your eyes. If the glasses are uncomfortable to your eyes that is going to make t very hard to be wearing them every waking minute which is every bit as important as the power of the glasses. Part time wear will have no effect on your eyes and do nothing to induce myopia. Cactus Jack over in the Vision Thread wrote out a perfect glasses prescription for you to start out with and I couldn't agree more. I really think you're going to find trying to see small print very difficult and even harder for any length of time. Cactus Jack has spend plenty of time working with you and advising you and if your not going to listen he is wasting his time.

Cactus Jack 18 Feb 2016, 22:58


This is not going to happen nearly as fast as you want it to. Have you tired your boyfriend's glasses before? You may be in for a surprise. You should have plenty of accommodation to deal with -2.25, but you could experience some mild problems. You should try wearing them in private first, before trying to wear them at school. Vision occurs in the brain and your brain has to learn how to interpret the different images. Your Ciliary Muscles are going to have to get used to squeezing your Crystalline Lenses for distance and squeezing them harder for close work.

We probably need to work on a story when you inquire about contacts. It needs to be plausible. Your first visit needs to just ask questions and satisfy curiosity. What color are your eyes?

There used to be an outfit in Vancouver, BC that sold Contact Lenses without a prescription, but they changed their policy a few years ago. Maybe some of our other members can suggest a source of contacts. However, don't order anything unless we chat.

Please let me know your experiences wearing your boyfriend's glasses. Particularly, what it is like reading the text on a smart phone with the glasses.


CJB 18 Feb 2016, 21:03

Thank you once again. I will get my boyfriend's glasses tomorrow at school, and start wesring them in school, and at home in my room or when my parents are not around. Then, on Monday I will try the mall optometrist to get my contact sizing. Where exactly would I order prescription contacts from? Is there a Zenni for contacts?

This is really hapening, I am going to make myself nearsighted, and it starts tomorrow!

Cactus Jack 18 Feb 2016, 18:38


It is common for people who are mildly Hyperopic to see a bit better than "Normal". It is why some people people who are Myopic like to slightly over corrected. It has the same optical effect as being mildly Hyperopic. The result is 20/15 vision or even in exceptional cases 20/10 vision.

The 20/20, 20/15 or 20/100 are called Snellen Fractions are are an indication of Visual Acuity. For example, if a person was said to have 20/100 vision, it means that they can see at 20 feet what a person with "Normal" vision can see at 100 feet. 20/20 is not really the best possible vision. You can read up on the Snellen Chart on the web and how "normal" vision was determined. 20/15 is much closer to "perfect" vision. I have not asked about your academic interests, Optics, Vision, and the eye are fascinating subjects that you should explore on your own if you are interested in this stuff. You want to wear strong Minus glasses, and you can. I suggest that you might want to learn how it is possible to Induce Myopia, but impossible to Induce Hyperopia.

I think your friends glasses are an excellent idea. You absolutely don't want glasses with any Cylinder, if your don't have any Astigmatism. Alll Cylinder will do is make your VA worse at all distances. You may at some point develop some Astigmatism, but the wrong Cylinder power or the wrong axis angle just messes up your vision.

It will take a while to Induce Myopia. There are two types of Myopia. Axial or True Myopia and Pseudo or False Myopia. They have two different causes, but one effect. Distant objects are blurry. Both can be present in one person and the effects are additive. The correction is to wear MINUS Glasses or Contact Lenses.

At your age, you might be able to Induce some Axial Myopia IF, your genes will let you. Axial Myopia is caused by a mismatch between the total power of your eyes lens system and the distance from the back of your Crystalline Lenses to your Retina. It can vary some, but typically the total power of your eye's lens system is about +59 diopters and the distance is about 17 mm. Good old Sir Isaac Newton formulated the equation for the relationship between Focal Distance and Lens Power.

Almost every baby is born with very high Hyperopia. This is caused by the eyeball having to be small to fit in the small eye socket in their small head, so they can pass through the birth canal. Fortunately, the baby is also equipped with extremely flexible Crystalline Lenses and Huge Accommodation Range. It takes them about a month to learn how to use their Ciliary Muscles to be able of focus images. As the child grows, it is believed, but not yet proven that the Retina produces a Eyeball Specific Growth Hormone (ESGH) as a result of the focusing effort. As the head and eyeball grow, the child becomes less and less Hyperopic until they have "normal" distance vision without any focusing effort. Ideally, eyeball growth stops. However, if the eyeball does not grow enough, Hyperopia results and if the eyeball grows too much, Myopia results. BTW, the distance involved with either Hyperopia or Myopia are about 0.3 mm per diopter.

The idea behind wearing MINUS glasses or contacts is to force your Ciliary Muscles and Crystalline Lenses to compensate for the artificial Hyperopia and cause the production of ESGH, IF your genes will allow it. If it occurs, you will be able to Induce some Axial Myopia which is considered permanent because once you eyeballs grow, they do not shrink.

Pseudo Myopia is caused by your Ciliary Muscles and Crystalline Lenses having difficulty relaxing for Distance after compensating for the extra MINUS in glasses or contacts. It is temporary, but that is a relative term. Unfortunately, when you are young, as you are, your Crystalline Lenses are very flexible and your Ciliary Muscles can easily compensate for the excess MINUS and relax back to "normal" very easily when you take the glasses off. Nevertheless, it is possible to Induce Pseudo myopia that does not go away too fast, but you have to really work at it.

Just to give you an idea of what is possible, I was able to help a young man who was a few years older than you, in college go from not being able to get a prescription because he was slightly Hyperopic and was reporting symptoms that didn't make sense to the ECP. He did the same test you did and we discovered why he was unsuccessful. He started with -1.00 glasses and gradually increased the power to about -3.00. With planning he went for an eye exam wearing his -1.00 glasses, complaining that he was having trouble seeing the board. He got a real prescription for reference, but continued with stronger and stronger self prescribed glasses. The last I heard from him his last eye exam resulted in -4.25 glasses.

In answer to your questions:

1. If you go for an eye exam for Myopia without planning and preparation, it is unlikely that you will get glasses. If you go wearing obviously more MINUS than you need, you will not get the results you want. You need to pay attention. I'll help you be creative, but inducing myopia takes time.

2. Contact lenses are a good idea, but you will never get a fitting unless you need them. You absolutely need to get a professional fitting for Contact Lenses. There are lots of things involved and it can be dangerous to try to self fit contacts. You need to have a good idea of the Base Curve and Diameter before ordering different Sphere Only contacts. Fortunately, there is a way to get some contacts, even if you don't really need them. You get fitted for contacts that change your eye color or special occasion "costume" contact lenses. The latter are popular around Halloween of a few other occasions. Eye color changes are good any time. It helps to have a good story and $. Once you have your Base Curve and Diameter, you can order Sphere Only contact that will likely be comfortable to wear of almost any power you wish. If you wear both contacts an glasses the effects will be additive.

3. The best clue that Inducing efforts are having an effect is reduced sharpness of distant objects when you first wake up in the morning. before putting on glasses or contacts. Also, at night, in low light conditions, stars are not pinpoint bright, but a little defuse without your glasses. It is not hard, once you know what to look for.

4. Once you get glasses, just keep ordering stronger glasses on line. If you don't change the frames or make an increase too large, few people will notice. It is pretty common for people with Myopia to need stronger and stronger glasses until their early 20s. Courses of study in High School or University that require a lot of close work and reading and be a significant factor in promoting increased Myopia.

The important thing, if you really want to do this, is to get started. The hard part will be convincing everyone that you really need glasses. The contacts are a good idea, I suggest that you come up with a good story for wanting color changing contacts or costume contacts and make some inquiries to find a source that is reasonably priced. You might check out a Wal-Mart Vision Center to see what the offer, but limit your discussion to that specific topic.


CJB 18 Feb 2016, 14:10

Cactus Jack

I do not know if this explains the off results and the reason you thought my left eye might be huperopic, but three moths ago when I had my eye exam I was told I see better than normal in my left eye 15/20, and normal in my right (20/20).

For the glasses stuff, is it fine if I just start off with -2.25. I ask this because my boyfriend has his his old -2.25 glasses. He also has every glasses after that, and he did not have astigmatism until last year, so his old ones do not have astigmatism.


1. I wear glasses before going to the eye doctor to create a need for when I do go, right?

2. Should I look into getting contacts to wear with my glasses to get a greater overall additive effect without letting people notice? Also, wouldn't they be a better way to start out because then I would not have to explain anything to anyone?

3. When exactly would I start hinying that my vision is getting bad?

4. Once I do get glasses, how would I be able to keep getting thicker lenses?

Thank you for all you have done so far, I greatly appreciate it. I cannot wait to get my first prescription glasses!!!

Soundmanpt 12 Feb 2016, 10:41


In doing some research I came across several posts from you mostly you were having a major problem worrying about what people were thinking about your suddenly wearing glasses. Have you ever gotten past carrying what others may think and started wearing your glasses on a daily basis?

Golf 11 Feb 2016, 17:15

Hi all,

Small update:

My glasses has already shipped and I expect to get them soon.

I'll upload a picture of them and will tell ya how the first day with them go through.

Best regards,

Likelenses 07 Feb 2016, 00:01


If I understand you correctly your real Rx is now -4.00, and -4.75.

For your age,you have made very good progress.

I think that you can still handle a stronger Rx, but I would suggest that whenever you do any close work be sure to wear the glasses,and hold the work as close to your eyes as possible.

Also when looking at distant things try to always squint.

The idea is to make it a habit to do all the things that a myopic person does.

MinusGirl 03 Feb 2016, 21:08

Olive, i had a similar experience as you, try to log in at lenschat, i used to enter there, to talk about what you lived last year, enjoy glasses!

Soundmanpt 01 Feb 2016, 13:33


Sorry I should have done my research better. I went back and found your post from Feb 2015 and you indicated that you had perfect eyesight when you started and that you were 25 at the time so by no you could be 26 or close to it. You said you were hoping to reach -10.00 for glasses. That might not be possible but you have managed to no longer have perfect vision and now your glasses are necessary and even if you're unable to induce anymore myopia you at least have a nice decent prescription and you pretty much need your glasses full time. So if you don't manage any additional myopia will you be satisfied?

Soundmanpt 01 Feb 2016, 13:13


So when you started inducing myopia did you have perfect vision at the time? May I ask your age? But I have to wonder if you were to stop wearing glasses if your vision would slowly try to return to normal? What is the ideal prescription you would like to end up at? Keeping the same frame with each increase is the way to do it so you don't get any questions about your glasses.

Olive 01 Feb 2016, 12:24

Hi all, been so long ain't post in here.

Michael, its true that since february last year I tried to wear glasses 24/7. At the first time I wore -3,75 and -4,00. I wore it from the time I wake up in the morning till night before going to bed. After 2 months (on April) I add my prescription to -4,75 and -5,00. Everything became so blurry for the first 3 days I tried to wear it full time. I still wore that glasses no matter what i struggle to see everything clearly, especially when I did my task in front of PC. But I didn't care. On June I've done my eye exam and how supprised I'm that finally I could became a myopic. Even my real prescription at that time was -2,75 and -3,00. So I decided to add -1,00 again on my glasses, in order to made my sight worse. I wore -5,75 and -6,00 full time since July last year. Neither my family nor my friends didn't notice that my glasses become stronger (i never change my frame model), only my bf noticed it. But he didn't take it too seriously. He just said that I should do eye check up every tine I feel that my glasses doesn't fit any longer.

Now, I can tolerate -6,75 and -7,00 glasses, even my real prescription is -4,00 and -4,25.

Chino 28 Jan 2016, 14:06

No results so far, and I don't think I'll get any from these lenses.

I was wrong in my assumptions about the S cone sensitivity and visible light transmittance for these lenses. I can clearly see blue light with these lenses. It's nowhere near as bright as it is without the lenses, but I'm sure that my ability to perceive it at all compromises my results. I'll keep using them until February 15, and then order my last pair with the ARG lenses.

Golf 25 Jan 2016, 05:20


it might be depands of the type of lens i thinks.. try to put a prescription now and see..

I have ordered two pairs of glasses from Zenni Optical with a 3 D cyl in them and there was no extra charge.

Cactus Jack 24 Jan 2016, 06:17


Tje 0.25 reduction in the Cylinder shouldn't cause a big problem. If you do notice it, you might go up to -5.00 in the Sphere and see if that helps.


Golf 24 Jan 2016, 05:29

Hi Cactus Jack,

Ofcourse i knew about the zenni site - and i swear to God i know orederd a pair as you suugested (change the CYL to -2.00 in order to avoid 12$ increase in rate :)

i'm from israel and work as Media Advisor.

thanks, i'll keep you updated.

Ben 24 Jan 2016, 02:42

Hello, I haven't posted here in awhile.

I did something stupid and forgot my high minus contacts/glasses back at school (which is a several hour drive from my home). So I only had the -2s for the entire vacation, which is a setback. I will not be making this mistake again.

However, when I was wearing my -2s during December, things in the distance were pretty blurry, and I struggled to read signs while driving at home.

I came back and started wearing the -6 contacts, sometimes experimenting with -4 and -2 glasses over the -6s, and that was too easy. No strain, no problems, clear vision. So I moved to wearing the -10 contacts full time that I purchased a month back. On the first day of wearing them, everything was blurry, distance and close up vision, but I could read everything on my computer screen clearly after wearing them for about 5 minutes, however, my distance vision took about an hour to clear up completely.

On day 2 of wearing the -10s (yesterday), things began to clear up even faster (about 2 minutes to see my computer screen clearly). It also took about 30 minutes for my distance vision to clear up, but after that everything was fairly clear.

A felt a little strain at first in the back of my eyes, but that quickly went away. I plan on continuing to wear the -10s from the moment I wake up to the time I go to sleep at night. I will try to update more often as well.

Cactus Jack 23 Jan 2016, 18:57


It is vey likely that you can Induce some False or Pseudo Myopia, but at your age, True or Axial Myopia is more problematic. Both have the same optical effect, but the difference is that Pseudo Myopia is considered to be temporary. If you stop wearing the stronger glasses, your vision will revert to your Axial Myopia level.

I suspect you could tolerate an approximate -2.00 diopter increase in your Sphere correction, but it depends on how much close focusing you do. If you know how, I would suggest ordering some very low cost glasses from an online retailer such as Zenni Optical with a frame that is as near like the one you are wearing, as possible.

Here is the prescription assuming the first line is for your Right Eye (O.D.)

-4.75 -2.25 005

-5.25 -1.75 180

The only other thing you need is your Pupillary Distance (PD). If you don't have it, it is very easy to measure.

You did not mention where you live. Here in the US, Zenni offers glasses for US$6.95 using their lowest cost frames. Their lowest cost Anti-Reflective coating is about US$4.95 and Shipping is about US$5.00. If you choose some low cost frames, you can try them and if you like them you can order nicer frames.

Generally, people do not notice the lenses only the frames. The AR coating will make the lenses even less noticeable.

May I ask your occupation and how much close work you do?


Golf 23 Jan 2016, 16:05


My exact prescription is :

-2.75 -2.25 005

-3.25 -1.75 180

I do want to induce some more myopia, I'm 24, how much raise do u think I can tolerate? I thought about -5D.


Chino 13 Jan 2016, 11:34

Quick update. Just got the new lenses today and am wearing them from now on. I'll give an update around mid-February.

Chino 12 Jan 2016, 17:05

Hi everyone!

Due to an unexpected turn of events, I am able to continue the experiment. As a plus, I've had some time to more thoroughly go through the selection of lenses, and I think I may have found an even better option than I was going to use before.

I'm using lens 505 from, in frame number 38W. I think this lens will give me better results than lens ARG that I had planned to use before.

With lens ARG, the optical density is 7+ up to 532 nm, which is well into the green wavelength. By the time the optical density drops below 1, you're well past 534 nm (the peak of m receptor sensitivity).

Lens 505 gets to almost 10% visible light transmission at 500 nm, and it goes up from there. I should have very good perception of green light. Perception of blue light should be minimal, as the threshold for blue light kicks in at 495 nm and below. By that point, visible light transmission is less than 10%, and dropping. By 500 nm, the S cone response is only about 10% of its peak response at 420 nm.

The combination of low visible light transmittance with low S cone response at these wavelengths should, hopefully, allow for a better experimental result.

As before, I'll give the lenses a month. If that doesn't work, I'll give lens ARG a try. If ARG doesn't work, I'm pretty confident that this mechanism won't work on adults. At that point, if there are any younger people who want to attempt the experiment, I'd be happy to send them my filter lenses.

Wish me luck.

Cactus Jack 27 Dec 2015, 08:28


I agree with the previous post. It is best not to try to cheat because there is no need to. Ideally, you want to get the most accurate prescription you can, particularly if you have any Astigmatism (corrected by Cylinder and Axis). I wrote a piece a while back called "How to Study for an Eye Exam.". I will post it in 2 or 3 parts on the Vision thread. You may find it useful.

Once you have an accurate prescription, even if it is very low, we can tell you how to order glasses with a low to moderate MINUS, if that is what you want. There are two types of Myopia. True or Axial Myopia (permanent) and False or Pseudo Myopia (temporary). They have two different causes, but produce the same result, a need for MINUS glasses.

At your age, it is very unlikely that you can Induce any Axial Myopia because your genes which control eyeball growth have probably turned that OFF. You may be able to still use your Ciliary Muscles and Crystalline Lenses to create some useful Pseudo Myopia for the next few years.

Please read"How to Study for an Eye Exam." It may be a few minutes before I have it all posted. After you read it, we can talk about Inducing Myopia. if you want to.


Soundmanpt 27 Dec 2015, 05:10


Never try and cheat because any doctor worth anything will quickly catch you. If your only wanting glasses all you need to do is be sure when you fill out the form before your exam to indicate that you are finding it difficult to see to drive after dark. Even mention it during the exam. This should get you at least a weak prescription of -.50 in both eyes and they will recommend that you get the AR coating (anti-reflective) which is helpful for cutting down on glare for oncoming car headlights. This is the one thing they are forced to take your word about.

Brian 27 Dec 2015, 04:48

Thanks Likelenses

Is there anything I can do during the actual test?

I am 27 and from the UK. Last time I had my eyes tested I was -0.25 in my left eye but the optometrist said its not worth getting glasses for such a low RX.

Likelenses 27 Dec 2015, 02:27


It all depends on many factors such as your age, your present visual acuity,time of day,and what visual condition you want,and a few others.

If you want to get minus glasses,and have normal vision,depending on your age you could try by scheduling an exam for late in the day.Do a lot of reading holding the book as close to your eyes as you can tolerate,for a few weeks prior to the exam,and especially the day of the exam,read for several hours,and even in the waiting room prior to the exam.Also get as little sleep as possible for those weeks.And stay away from activities requiring a lot of distant viewing.

Brian 27 Dec 2015, 01:10

Does anyone have tips on how to fail an eye test?

 26 Dec 2015, 16:08

I don't believe to much in all these stories about induced myopia. When I was younger than now, I always wanted to wear glasses. When I went to university I wore every minute -2,00 for both eyes, and sometimes up to -5,00. But -2,00 all the time, between 20 and 29 years (-2,00 was my maximum for reading distance). In yearly visits to eye practioners I never could convince one to prescribe me glasses.

When I was thirty, One of them found out about slight astigmatism. and he made a test with drops in the eyes.

And so my first prescription was, after nine years of full-time wearing -2,00 on both eyes:

Right eye: +2,50 sph / - 1,50 cyl Axis 90

Left eye: +2,50 sph / - 1,00 cyl Axis 100

So I was quite happy with my glasses then, and I could see much, much better then.

Now I am at

Right eye + 4,25 / - 2,75 cyl A 88

Left eye + 4,00 / - 2,25 cyl A 95

plus reading addition, sometimes using +8,00 CLs in both eyes for a nice, nice GOC.

I have a pair of -10 I wear occasionally, I have a true myopia of -3.50 (-0.75 to 90 °), you are young I think you get to see quite easily with. But be careful if you plan to wear them full time with age you no longer come to bear as well.

Ben 20 Nov 2015, 22:38

Cactus Jack,

It is no problem, I understand that one cannot remember everything.

Right now I have been considering purchasing a stronger pair of contacts, like -10, and work my way up with my -2 glasses, -4, and then -6. I want to make this large of a jump with my contacts because contacts are kind of expensive.

I will keep you updated as much as possible.

I apologize for not remembering your age and the other particulars you had posted earlier. At 78, I still have pretty good memory, but I just don't try to keep up with everyone. You have a lot of things going for you.

One 28 YO, very highly motivated member, who had about -4.50 Axial Myopia was able to work up to wearing -20.00 glasses while studying. If you translate that back to the Cornea using the formula of Vertex Distance effects and subtracting his Axial Myopia, he achieved a bit over +13 diopters of accommodation, but it did not happen overnight. When he had achieved his objective, his vision gradually reverted to about -5.50 which seems to be mostly Axial Myopia.

When you are wearing the -6.00 contacts and the -6.00 glasses, the effective power at the Cornea is about -11.50. With your Axial -2.25, you are accommodating about +9.25 for distance and about +11.75 for reading. When the -6.00 glasses get comfortable for reading and you don't really notice that you are having to expend any accommodative effort, consider -7.00 either in the contacts or the glasses.

Please keep up posted on your progress.

Cactus Jack,

I am 18 years old, and I am a university student studying computer science.

My -6 contacts are super easy to use now, no strain, and I forget that I even have them on. Also, my vision during the night with my -6 contacts is really good.

I have been wearing my -4 glasses over my contacts fairly often for several hours, and that is becoming easier and easier. I am trying to work myself up to -6 glasses over my -6 contacts for everyday use, but as you stated, depending on my level of fatigue, my vision and ability to accommodate changes.

Cactus Jack 20 Nov 2015, 08:49


Your ability to wear significant over correction is dependent on the strength and conditioning of your Ciliary Muscles and the flexibility of your Crystalline Lenses. It is normal for that to vary some based on fatigue levels. The Ciliary Muscles are like any other muscles, just very tiny. They respond to exercise and stress. Wearing over correction is not really much different than lifting weights at the gym. You don't start with the heaviest weights, you have to build up over time. Also, muscles can become fatigued and need rest to recover their full strength after exercise.

May I as your age?


Ben 19 Nov 2015, 14:28

Trying the -6 glasses over -6 contacts again today, I can read up close with ease now for some reason. So I can read up close with -10 over correction now. Strange.

Ben 19 Nov 2015, 14:28

Ben 19 Nov 2015, 07:15


Thank you! Yes, I can do close work with my over correction of -8! It took some time to work up to it, but eventually my eyes allowed it. At first over correcting of -4 was kind of blurry, but now it's super easy.

This morning I tried my actual prescription really quick after I got up, and things were blurry at a distance. I could no longer read things 10 ft across the room. I have been relying mostly on my -6 lately, however I have been experimenting with -8 and -10 as well.

til 19 Nov 2015, 05:42


Congrats on being able to cope that well with such a massive overcorrection. I would really like to be able to accommodate that much minus power as well but I don't seem to get there anymore. At 27 I'm quite a bit older than you and I don't require any correction yet. I do wear -3.5 every day and -6 in the evenings but the stronger prescription already gives me a hard time in the late evenings, especially with computer work. For some reason my girlfriend who actually is a low hyperope can cope a lot better with minus prescriptions which partly annoys me;-)

Are you really able to do close work with an overcorrection of almost -8?

Ben 18 Nov 2015, 22:31

I have mostly been wearing my -6 (contacts or glasses), but now I am starting to play around with wearing my-2 contacts under my negative -6 glasses, and wearing my -4 glasses over my -6 contacts. They work well, saying my -6 is so easy to wear now. As soon as I put them on everything is clear, no strain, no headaches.

The -6 glasses over my -2 contacts was not much of a jump really, it felt almost exactly the same as my -6. The -4 glasses over my -6 contacts is not bad, takes a second or two to get used to them, but after that it's fine.

I have briefly tried my -6 glasses over my -6 contacts, and that is a bit harder, and it takes a few minutes to see with those. I am sure overtime that I will be able to work myself up to that point.

I will keep you all updated with what is going on as it happens.

Ellie 03 Nov 2015, 18:14

Hi Ben!

I've been following your posts about inducing myopia. For some reason it is very exciting to hear that another college aged student is so interested in wearing high prescription glasses as well! It is not something that I really get to indulge or share with most people my age. Good luck on your journey! :)

Ben 02 Nov 2015, 12:12

The -6 contacts came in today. I put them in and after about 5 minutes the blur disappeared. I am feeling no strain at this point.

Ben 01 Nov 2015, 21:58


I have an older brother and he has been wearing contacts since he was about 13, but I have never seen him with glasses nor have I seen any of the boxes his contacts came in.

My parents originally thought I was lucky and somehow their genes skipped a generation but instead my eyes have changed through the last few years.

I will keep you updated as much as possible, right now it seems my eyes are adapting quite well to the -2 glasses over -2 contacts, and it feels as if all the tiny amount of strain I had from reading earlier went away, even as I pull my phone really close to my face like I am now. I plan to move up in strength as soon as the contacts and glasses I ordered get here. I'll try wearing my -6 contacts when they come in and see how that works out.

GreginColo 01 Nov 2015, 21:08

Ben good luck with your efforts to increase you level of myopia; it sounds like you are off to a good start and making some good progress. I am surprised you didn't end up with more myopia naturally, given your parents Rx's, each about triple yours. I would be curious if you have siblings and what their Rx's might be. Keep us informed of your progress. Thanks.

Ben 01 Nov 2015, 18:24

Cactus Jack,

Ah, I understand what the formula is now. Thank you for explaining it.

I took Physics my senior year of High School, but my teacher did not do a great job at explaining it, since we were near the end of the year and they were just trying to get topics finished.

We unfortunately did not talk that much about the eye during that topic of class.

I am starting to read the page that you linked me and I find this to be very informative, and quite interesting.

Cactus Jack 01 Nov 2015, 18:02


It is the most basic formula in Optics. It was discovered and codified around 1700 by Sir Isaac Newton of Gravity fame. Here is the formula or equation:

Focal Distance = 1 meter or 100 cm or 1000 mm or 39.37 inches divided by the Lens Power in Diopters.

You can also rearrange the equation like this:

Lens Power = 1 meter or 100 cm or 1000 mm or 39.37 inches divided by the Focal Distance.

Of course the units of measure for the distances have to be the same for the Constant 1 meter and the Focal Distance.

When you wear more MINUS than you need, you are moving the focal Plane behind your Retinas and depending on your Ciliary Muscles and Crystalline Lenses to add enough PLUS to neutralize the extra MINUS and move the focus distance up to your Retinas. Hopefully, this will stimulate the production of Eyeball Growth Hormone and your eyes will grow a bit to compensate.

You might find this link interesting:

Have you studied any Physics. Optics is usually part of that subject in school.


Ben 01 Nov 2015, 17:32

Cactus Jack,

I have heard of it from some of your previous posts but I am not 100% aware of what it is.

Cactus Jack 01 Nov 2015, 17:29


The text size probably does not matter unless you are having to get closer to the screen to read it. Are you familiar with the Sir Isaac Newtons formula that relates Focus Distance and Lens Power?


Ben 01 Nov 2015, 17:23

The slight strain is more when I read. I am pretty close to my computer screen and I set the text to be very tiny in my browser. The strain is very negligible, I don't really notice it unless I really think about it.

Cactus Jack 01 Nov 2015, 17:18


That is a good start. Are you noticing the slight strain when you read or at distance?

For Distance, your Ciliary Muscles and Crystalline Lenses are having to supply about +2.00 to compensate for the extra MINUS, but when you read with your glasses and contacts, they are having to supply +4.50 to +5.00 depending on how close you need to focus.

You also might find that some Lubricating Artificial Tears helpful if you are not blinking enough to keep your Corneas and Contacts moist and lubricated.


Ben 01 Nov 2015, 16:59

I have been wearing -2 glasses over my -2 contacts today and it's quite easy to handle. I can feel a small bit of strain in the back of my eyes after wearing them for 8 hours but it's barely noticeable.

Ben 01 Nov 2015, 10:22

Hello Cactus Jack,

Thank you for the fast response.

1. I am not sure about my grandparents prescription, but my parents prescription I know. My father has -6 contact lenses and my mother wears around -7 glasses.

2. As of right now, I live at school a few hours away from home, so if I was going to go to an ECP here, they would have no clue about who I am/my families history. If I were to go to an ECP, I would also probably just pay out of pocket for it, so that I don't need to rely on my parents or their insurance.

I believe my -6 contact lenses will be in the mail Monday or Tuesday, and my new glasses will be here in about a week. I also have my old -2 glasses that I could wear over contacts if needed.

Thank you again!

Cactus jack 01 Nov 2015, 03:05


You have many things going for you. Your age and your genetics are on you side and your visual environment will help.

You have the right idea with your glasses and contacts. The initial thing that will occur is your Ciliary Muscles and Crystalline Lenses will need to supply the compensating PLUS for the extra MINUS, which is Pseudo Myopia. However, at 18 your Ciliary Muscles and Crystalline Lenses are very flexible and they will quickly relax. Wearing as much additional MINUS as you can tolerate has the same effect on the Ciliary Muscles as weight lifting at the Gym does on your other muscles. The idea is that by keeping your Ciliary Muscles under stress, it will stimulate the production of an Eyeball Growth Hormone.

A measure of how effective that might be can be ascertained by reviewing how your Axial (True) Myopia has increased in your teen years as a result of normal academic stresses and overall growth during that period.

One of our highly motivated members, who was in his late 20s at the time, was able to increase his apparent myopia from around -4.00 to where he was wearing -20 glasses full time and even studying for advanced academic credentials. Vertex Distance effects at the -20 level reduced the effective Myopia at the Cornea to a bit over -15. When he read with his glasses his effective Myopia was -17.5 to -18. It took him about a year to get to the point where he could wear the -20 glasses, but he ultimately accomplished his objective and achieved about -5.50 diopters of Axial Myopia.

The key factor limiting how much Pseudo Myopia he could achieve was his age and the strength of his Ciliary Muscles. His genes ultimately limited how much Axial or True Myopia was possible. The point is that if you are serious, how much you wear your over correction seems to be more important than the actual amount of over correction. However, both are important and there are no guarantees of ultimate success. Just remember that when you get comfortable wearing say your -4 glasses full time, it is time to go to the -6. If you can, try for -1.00 increase per month. The trick for avoiding questions is to keep the same frame style. Whatever happens will not occur overnight or as quickly as you would like. The clue that you are making progress is when your distance vision is blurry, first thing in the morning, with your previous prescription.

Two more questions:

1. Do you know your parents and grandparents prescription (Approximate)?

2. Are there several ECPs that you can chose from for eye exams? You probably don't want to use a "family" ECP who knows your family's visual history.


Ben 01 Nov 2015, 02:19

Also just to note: I only purchased the -4.25s so I could wear them over contact lenses, so that when I get to the point where I will wear the -6.25s over contact lenses, not that many people will notice the difference in strength because I got two of the same frame. I plan to move past that as time goes on.

Ben 01 Nov 2015, 00:45


I have been looking to induce some myopia. I am 18 years old, a computer science major in university. My current prescription is R: -2.25, L: -2.5. I have purchased glasses with the strengths of:

R: -4, L: -4.25.

R: -6, L: -6.25.

I also have plenty of -2 contact lenses laying around and I have purchased -6 contact lenses. I was wondering if I can also induce by combining the powers of my glasses and contact lenses.

I understand that I must increase in the same power for each eye, and I understand that I must keep these on all day in order to induce, and I have no problem doing that since I wear glasses and contacts interchangeably already.

I am looking to get up into the -8 to -12 range, but any increase in prescription would be fantastic. Most of my family is myopic so it would seem that it runs in the family.

I used Zenni to purchase these glasses, and my finances are completely separated from my parents at this point, so they do not question a thing (also I live at school).

I was looking for any extra tips/recommendations I might need in order to induce.

Thank you very much.

Cactus Jack 25 Oct 2015, 05:32


You did not fully answer my questions, but I will offer suggestions based on what you wrote.

There are 3 important elements in a glasses prescription. By tradition, the first number is the Sphere correction, the second number us the Cylinder correction and the third number is the Axis or direction of the long axis of the Cylinder. Cylinder and Axis ALWAYS go together. You CAN NOT have Cylinder without also having the Axis.

Sphere corrects for a mis-match between total PLUS power of the eye's lens system and the size or the length of a person's eyeballs. The total PLUS power of the lenses in a "normal" eyeball is about +58 diopters and distance from the back of the lens system to the Retina is about 17 mm.

Cylinder corrects for Astigmatism which is typically caused by uneven curvature of the front surface of the Cornea. Ideally, the Cornea should be a very smooth, even shape like a section from the side of a small glass Sphere. Sometimes, the Cornea has the shape of a section from a small glass American Football where the curvature is greater in one direction than in the other and has more PLUS power in the short axis than it does in the long axis. By tradition, the Long Axis direction is the Axis of the Cylinder.

The Axis direction, by convention, is 0 degrees, horizontal. The numbers increase counter-clockwise (looking at the patient) to 90 degrees vertical and on around to 179 or 180 degrees which is the same as 0 degrees. Axis numbers are always between 0 and 180 degrees.

A typical glasses prescription looks like this:

OD (latin for Right Eye) or R Sphere, Cylinder, Axis

OS (latin for Left Eye) or L Sphere, Cylinder, Axis

Sphere and Cylinder either be a + or - number, Axis will just be a number without a + or - sign. If the Sphere is 0.00 it may be listed as Plano or 0.00, If the Cylinder is 0.00 it may be left blank or in English, N/A for Not Applicable. If no Cylinder correction is needed the Axis is also blank.

You listed your prescription as:

R -0.25

L Plano

without any Astigmatism correction.

There are a few simple rules for changing your prescription.

1. You ONLY adjust the Sphere correction. Never adjust the Cylinder or Axis, but include them exactly as prescribed.

2. You change the Sphere correction by the SAME amount in each eye.

3. If you don't change the frames, few people will notice that you did it.

You said that you would like to increase your prescription by -1.00. Using the rules above here is the result:

R -1.25

L -1.00

Assuming you do not need any correction for Astigmatism.

You should be able to wear the above prescription, but if you want to Induce some additional Myopia, you will probably need to work up to -3 or -4.

On thing that is working against you is your age. The primary controlling factor in needing vision correction is Genetics. the secondary factor is your visual environment. The fact that your vision without correction is quite good after years of study and close work is a good indication that you will have difficulty in Inducing Axial or True Myopia. However, you may be able to Induce some Pseudo or False Myopia. The two types have different causes, but the result is the same.

Axial or True Myopia is caused by excessive eyeball growth from Childhood. Most babies are born with Hyperopia because their head and eyeballs are small to pass through the birth canal. Fortunately, most babies also have excellent Accommodation and can learn to use their Ciliary Muscles and Crystalline Lenses to compensate. As you grow, your eyeballs grow and your Genetics stops the growth ideally when you have 0.00 refractive error. Axial Myopia is considered to be permanent.

Pseudo or False Myopia is caused by the Ciliary Muscles and Crystalline Lenses (your Auto-Focus mechanism). It is actually the same thing as Latent Hyperopia, but on the other side of 0.00. You may be able to develop some Pseudo Myopia, because it is related to your Visual Environment rather than Genetics. Pseudo Myopia can last for a long time, but it is not considered permanent.

The important thing is that if you really want to Induce some Myopia, you need to get started as soon as possible. Inducing either type is a slow process.

May I ask what you are studying?

Please let us know what you plan to do. We can also offer some tips on how to help your friends and family get used to your needing glasses. It is not hard, but it takes a little planning.


Bruce 24 Oct 2015, 21:39

Cactus Jack,

Hi. Im still a student w/ lots of reading/close work to do. Unfortunately, i not live in the US, but i think i found a way to get some prescription glasses. Do you think i can still induce true myopia w/ using -1.00 glasses for about 10hrs a day or i can use a higher one for faster results?My family and friends know that i do not need glasses for full time wear so i can just use it when im alone. I went for an eye exam bec i was having hard time driving at night. Thanks for your answers

Cactus Jack 24 Oct 2015, 20:48


At 22, it is extremely easy to wear -1.00 glasses and even a bit more if you wish. You should have plenty of accommodation range available to compensate for the extra MINUS.

All you have to do is order some glasses with the prescription you desire from an online retailer. In general, they will not verify your prescription.

Many of our members order glasses online from Zenni Optical. We can tell you how, it is easy and can be inexpensive if you order inexpensive frames and standard lenses. Here is what you typically need:

1. Your complete prescription. We will tell you how to modify it and what to order.

2. Your Pupillary Distance (PD). If you don't have it, we will tell you how to measure it.

3. A Credit Card.

Typical delivery in the US is about 2 weeks.

We can even tell you how to deal with your family and friends when you start wearing glasses and and how to change your glasses prescription without comments from your family and friends.

I recently ordered a trial pair from Zenni (as a test) for a friend and the total cost including Anti-Reflective coating and shipping was US$16.85. He likes them better than his $250 glasses from a local Eye Care Professional.

May I ask where you live and your occupation? What prompted you to get an eye exam? The answers affect our suggestions.


Bruce 24 Oct 2015, 19:15

Hi, im 22, current prescription is R -0.25 L plano. I would love to increase that to at least -1.0 for both eyes. What do you guys recommend?

Chino 24 Oct 2015, 11:05

Hi everyone. Sorry I've been away for so long. I've been taking care of a personal matter, and just haven't been able to carry on with the experiment.

Once my schedule clears up, I won't have anywhere near as much time to wear any new lenses I try, which will slow any results that may be achieved. I also don't have an estimate as to when I can resume the experiment.

If anyone else is interested in picking up where I left off, please let me know. I'd be more than happy to share additional information and resources to help with the experiment.

Cactus Jack 18 Oct 2015, 19:25


That is a good question, that may not be answerable. The problem is that everyone is different.

Pseudo Myopia is in many ways the same phenomenon as Latent Hyperopia, just on the other side of 0.00. There have been occasional reports of people in their 50s and 60s, who have been myopic for years, having a reduction in their MINUS Sphere correction. There is really no practical way to determine whether this reduction is caused by Presbyopia or the development of Cataracts. The development of Cataracts is often the cause of what is sometimes called 2nd Sight in older people, but it does not happen to everyone.

It is impossible to say how much longer you can enjoy over correction, for a couple of reasons. You did not mention your age, your prescription, or the amount of the Bifocal Add involved. Both Presbyopia and Myopic Over correction involve the Crystalline Lenses and the Ciliary Muscles. The amount of over correction you can wear depends on your available Accommodation Range and the strength of your Ciliary Muscles. Presbyopia actually starts in childhood, but usually does not become a problem until the late 30s or early 40s. Most children have the ability to effortlessly focus very close. However, that ability gradually fades as the Crystalline Lenses become gradually stiffer and your Accommodation Range is gradually reduced. When it drops below about +2.50 or +3.00, you begin to notice that your arms are too short.

Lets say that you like to wear -3.00 over correction for distance and that it requires your Ciliary Muscles and Crystalline Lenses to use all of the available +3.00 to compensate. In that situation, you would not be able to focus close at all without some external help (an ADD). How much ADD you need depends on the distances involved as calculated using Sir Isaac Newtons basic optics formula: Lens Power = 1 meter (100 cm, 1000 mm, or 39.37 inches) divided by the Focus Distance in the same units of measure. If you used up all your accommodation with over correction, you would likely need about +2.50 (or a little more) to read and about half that to use a computer. Trifocals anyone?

When you no longer have any Accommodation Range left, you would not be able to deal with any over correction. If you developed any Pseudo Myopia, it is possible that your Crystalline Lenses and Cillary Muscles might very slowly relax some, which would reduce your Pseudo Myopia. How much, no one knows, even if you had an identical twin. There may be a difference in the visual environment and that would affect what happens. My advice is to enjoy it while you can and be thinking about GOC if you want to wear higher MINUS glasses that you actually need.

Any other thoughts or comments would be appreciated.


Question 18 Oct 2015, 15:40

Hi all, just a question - when presbyopia sets in, does it eliminate pseudo myopia completely? Or just a little bit? Can bifocals be worn for the actual presbyopia and the over correcting myopia? Or is over correcting gone, or just reduced?

LXW 14 Oct 2015, 03:34

Hello Jo,

i am also very interested to do surgery with ICL for my eyes.

Hope there are some other people!


Jo 13 Oct 2015, 22:11

hi all,

i am based in china. And i'm a GOC myself and have been exploring the option of doing Icl for many years to no avail.previously have tried enquiring in Thailand, but made very little headway. Now that i'm in China and ICL is the rage for high myopes, i'm beginning to think there might be a chance that i can find someone who would be willing. Yet if it's me and me alone, i am doubtful that they will be enticed to do the operation where there's little to gain. On the other hand, if there's a group of us, I figured they might me keen since that means a great amount of earnings. So wondering, how many here are interested?

NJ 13 Oct 2015, 11:36

Jarred, yeah, close vision can be enhanced with high plus glasses by pulling them down a little. Also true for high minus. There is a limit though. If the glasses are too far down the angle looking through the lenses is too big and the image blurs. It's great for seeing items on the grocery shelf, but not to read the ingredients.

There are two difficulties with high plus glasses, the lack of peripheral vision, and the small bifocal part. The total area you can see out of a high plus bifocal is very small, so it's a constant battle to bob and turn my head to read a newspaper. I use SV lenses with my reading script for any extended reading.

The peripheral vision thing can be partially overcome by constantly turning my head, but if there are a lot of moving objects like people in a crowded store, it's hard to navigate.

It's not nearly as bad as most websites on cataract surgery would have you believe, though. Once you get used to the perspective and adapt, it's just not that hard to see.

Jarred 12 Oct 2015, 09:45

Hi NJ,

Thanks for sharing your story. I would love a decent level of myopia say around -14, but I have issues with prism which would mean it would be very tricky to deal with on top of the -14, I'm not sure I could ever have the guts to take the plunge myself. Which is a pity.

I have had some minor issues with my vision my entire life but sadly none that involve a decent level prescription.

Messing around with GOC over the years I have noticed that dealing with close vision is pretty easy if you are myopic and with the higher prescriptions whether it be + or - you can just slide the glasses down to fine tune focus, I recon its easier than bifocals or varifocals. I'm not sure I could convince my optician of the merits of high myopia though.


LEO in PERTH 10 Oct 2015, 05:24

Thanks NJ. I love doing GOC,but I told wearing contact full, is not a good idea , and that's the problem.

 09 Oct 2015, 17:10


Thank you a lot for sharing your experience and providing some links to start. Very appreciated.

In my case I just want to increase a little my current weak plus prescription. From +1 to +5 let's say. I'm wearing GOC most of the time to archive moderate hyperopia, which is pretty annoying sometimes.

So I think its possible to perform LASIK procedure for me, exactly the same as to correct myopia from -4 to zero. Just need to find friendly clinic.

NJ 09 Oct 2015, 10:43

Hi Jarred, happy to share a bit about my experiences.

I'm in my 50's and have been an OO since early childhood. In the first grade I deliberately failed a school eye test, got sent to the doc and was thrilled to find out I was actually farsighted. First glasses were 3-4D, guessing, and wore them intermittently but enjoyed them when I was in the mood. I have some family history of hyperopia.

Middle school and high school I didn't wear them a lot, mostly for social reasons. I could see fine without them for the most part. In college I found I really started to need them. Prescribed myself bifocals over the SV script I had and wore them all the time. In my senior year I first did GOC using -25D CLs under +20D glasses. Worked OK but did some fine tuning in the next few combinations.

I moved to another town for grad school and then med school, and took this opportunity to become known as a severe hyperope. Previously I was fairly secretive. In my new town people saw me with my high plus glasses regularly, but also often with my contacts. That's just how I was known. I also secretly tried high minus GOC combinations, which are generally much easier to wear but I was less interested in this.

So in most respects the surgery was no big deal. It just meant I didn't have to wear contacts anymore. The one surprise, which really shouldn't have been a surprise, is that life is different when your default goes from having decent, though not perfect, vision to having really poor vision. It's funny, but I probably wear my contacts as often as I do my glasses because it is easier to see. I wear contacts about half of the time, glasses the rest of the time. I also have a weak Rx for cyl and reading that I wear over my contacts, so I alternate between regular glasses and thick glasses. Some of my current work is difficult to do with the thick glasses, so I am thankful for contacts.

Surgery is a big decision, so I suggest you get very comfortable wearing GOC full time before you pull the trigger.

Jarred 09 Oct 2015, 10:21

Hi NJ,

Would you be prepared to tell us a little of your experiences since having the surgery? Have you managed to get back into your normal lifestyle, what prescription did you end up with? I have seen aphakic people driving etc. What sort of responses have you had to glasses. Do you have a 'day off' and switch to contacts?

I've messed about with GOC with both plus and minus glasses and in some cases being able to slide them down for reading is almost a benefit certainly needing a high minus can be handy. High plus on the other hand has some unique properties.

It would be interesting to hear your story.


NJ 09 Oct 2015, 09:30

CJ, I was merely offering a couple of places that would do surgery to worsen eyesight. I'm well aware of the optics involved and was not suggesting a simple clear lens extraction to increase myopia. That should have been evident from my closing comments.

...and I doubt most ECPs are aware of BIID as it pertains to this matter. There just aren't enough cases of it for your average ECP to ever have seen one.

Cactus Jack 09 Oct 2015, 08:49


If you had your Crystalline Lenses removed and no IOL installed, that is the same surgery as was performed prior to the development of Intra Ocular Lenses (IOLs). The result for most people is extreme Hyperopia, NOT Myopia, which then requires the use of very high PLUS glasses, which in turn, causes loss of peripheral vision, etc.

The only exception is those rare situations where a person has extreme Myopia. Removal of the Crystalline Lens, which is typically around +15, will reduce their Myopia and reduce their MINUS prescription.

Most people on this thread are seeking to INCREASE or as the name implies, Induce Myopia. To surgically Increase Myopia, you MUST have a PLUS ICL installed or the modern form of Cataract Surgery and have an IOL installed with HIGHER PLUS than your natural Crystalline Lens had. I believe the highest power IOLs are around +30 which would yield about a +15 increase and require about -20 glasses to correct for distance. To go beyond that would require a PLUS ICL (Internal Contact Lens) or regular PLUS Contact Lenses in addition to the IOLs.

One caution about having IOLs installed. If you change your mind about the power or type of the IOL, the only option is complete surgical removal of the IOL and the natural lens capsule or sack. The result is the same as having the old type of Cataract Surgery and the need for very high PLUS glasses.

As far as explanations go, I think most Eye Care Professionals these days are very aware of BIID in its various forms. While they may not be willing to consider performing the surgery, if it has already been performed, they will deal with a fait accompli or ask you to go elsewhere. Why you had the surgery performed is a Private matter. The only exception to that, is if a 3rd party payer is involved.

LEO, it was about $3200 for both eyes.

LEO in PERTH 09 Oct 2015, 06:54


Thanks NJ for that positive info, something to aim for! If I may ask, was it very costly?

NJ 07 Oct 2015, 10:09

This place was also willing to do the surgery.

NJ 07 Oct 2015, 10:05

LXW, I had the procedure done here:

There are lots of medical clinics in India and Mexico that will do this, though to be fair I didn't pursue my inquiries too far with most of them. I should think that if you are willing to pay them, they'll do it. In my situation, wanting to be a plus wearer, the procedure is very simple. I did have a cover story in case I needed one, but no one asked. I just came with my best guess Rx for correction post-op, and it was close enough. I did take a little explaining when I came back to the states to get my first real Rx, as the ECP recognized that the surgery was recent and wanted to know why I didn't get an IOL. That's when the cover story came in handy. I said that I have low vision and need the magnification. During the eye exam I had to limit myself to the 20/40 line with full magnification, just to be credible. Now I have an ECP who just does the refraction without asking questions.

I'd think that having an ICL in place to induce high myopia would present more of a problem explaining.

LXW 07 Oct 2015, 08:36


interesting to read your lines. Please tell me more about it, i haven´t found any solution until now. My biggest dream is to have ICLs with plus power installed in my eyes (to get myopic). But it´s very hard to find someone who will do it to my good eyes, for me impossible.

I have read a lot and also changed thoughts with members from here.

Thanks for answers,


NJ 07 Oct 2015, 06:03

With medical tourism, it's relatively easy to have eye surgery done that will give you whatever vision you want, within the bounds of possibility. I found any number of places that would do a clear lens extraction without IOL and the cost all in was less than I would have paid here in the US.

I don't think this is likely to become a recognized form of BIID given that so few people have this condition.

Can anyone tell me where I can buy contact lenses with a sph value higher than +20 dioptre? I currently wear -18.00 wiulglasses over contacts, but would love to go higher.

I don't think that it will ever happen in America,but if laws are enacted to allow it,other laws should be put into place that, that person should never be given any government paid for healthcare or public assistance related to the disability that they created.

astigmaphile 04 Oct 2015, 08:56

Cactus Jack,

While it may be possible to give people the vision that they want, you will never get it in America. You would have to travel to a foreign country. The U S is terrified of lawsuits. I have desires like this myself, but probably will never try to do anything about it. I have had a fascination with glasses since I was in grade school in the 1950s.

LEO in PERTH 04 Oct 2015, 08:00

Specks for ever

How you going ?

I think IOL (for wanna be myopics ) like myself , should be referred to as Cosmetic Surgery. All I ever wanted to do was wear high myopic glasses, for most of my life. Since the age of 10, 53 years ago.

specs4ever 04 Oct 2015, 07:48

I too noticed the news article about the woman using drain cleaner to blind herself. I thought that this was a bit too extreme and wondered if she could have had very high plus lenses inserted in her eyes to make her extrememly nearsighted if this might have been a better solution for her. At least by being extremely nearsighted she would then have had the option of wearing a pair of glasses if she had decided that being blind was not what she really wanted.

While it will never happen in my lifetime I suspect that within the next 15 to 20 years more people with BIID will come out of the woodwork and with the ability to choose your prescription will become an option for many. It really is no different than a gender change

If One could do GOC full time, it certainly will solve the Problem? A lense replacement would be great.


Cactus Jack 04 Oct 2015, 00:33


It took years before Cartlyn Jenner had the options she presently has. I believe that someday rather soon, the ability to reasonably select the uncorrected Vision you would like to have, will be possible.

When you get right down to it, there are two big issues for the Eye Surgeons

1. The Hippocratic Oath to do no harm. (In other words, make your vision worse so you have to wear more significant vision correction)

2. Liability issues should something go wrong or being later sued, should the patient change their mind.

Here in the US, I have noticed that some eye surgeons are advertising Elective Multi-Focal IOL surgery and an option to avoid the need for Bifocals or Trifocals. They mention that a side benefit is that it is the same Cataract Surgery and the procedure will eliminate the need for Cataract Surgery in the future.

Before the discovery that certain plastics could be inside the eye for years without problems, Cataract surgery was considered to be a very risky surgery because the entire lens capsule or sack and the clouded Crystalline lens was removed. This resulted in exposing the Retina to both the Vitreous Humor and the Aqueous Humor. Often the Retina became inflamed and blindness occurred. Often the patient was bed ridded for months with their head mobilized while the eyes healed. Today, Cataract Surgery with IOLs is close to a non-event and considered one of the safest surgeries.

You can thank the British fighter pilots in World War 2. A few years after the war, it was discovered that many former fighter pilots had slivers of Perspex Acrylic Plastic inside their eyes without any problems. The slivers had come from their aircraft canopy when it was hit by German bullets and some of the slivers entered their eyes.

I have been peripherally involved in a couple of cases. As a policy matter, I do not judge another person's needs or desires. However, I strongly suggest that they work their way up to very high prescription GOC and wear that full time, before committing to an irreversible surgery that they will have to deal with for the rest of their lives. This is particularly important where the person want to have their Crystalline Lenses and their capsules removed. Even wearing very high PLUS glasses, their peripheral vision loss is very hard to deal with.

Replacing the Crystalline Lens with the strongest PLUS IOL and installing a high PLUS ICL between the Cornea and the Iris can result in the need for very high MINUS glasses, but that is optically less dramatic than needing very high PLUS glasses.

One of our members has had both IOLs and ICLs installed because of a BIID desire to be very Myopic. He was satisfied for a few years, but is now wanting to be even more Myopic.


Mike 03 Oct 2015, 21:44

I think there should be more focus on BIID. People suffering should have treatment options and should not have to resort to these extremes. Look at Caitlyn Jenner she had options that didnt require drain cleaner or wanding into Mexico for options. WTF

hi loveglasses! you´re not the only one with glasses fetish, tell us how strong would you like to reach? how old are you? male or female?

Robert S 16 Sep 2015, 02:51


Hard to say probably a little of both. I tend to go bare eyed especially when I am doing close work so I am used to seeing everything blurry and can interpret blurry letters pretty decently. I do notice I cant read the text on shampoo bottles in my shower anymore and my comfy spot for reading stuff getting closer. I can put my -3's on and instantly see clear with them the -5s take a few seconds the -6's a bit more. As for the blur I do a test and look at the edge of the lens and compare the clear image through the lens and the blurry image outside the lens and it is more blurry than what I see bare eyed so my myopia isn't that severe. I took my -6s to work today and I was able to keep them on most of the day. I rode in on my bike with my -8s. I use the same frame for both but the -8s are much more noticeable Zenni got the order reversed and used 1.50 index on the -8's and 1.57 on the -6's which I don't mind. Right now I am spending time making a web site so it is a large amount of time reading smallish text and I managed to work most of the day using them when I get tired take my glasses off and I am usually 8-12 inches from the screens after a while my neck starts to hurt so I am back to using the glasses. I use my -3's when I had a long day and cant focus anymore with the -5's.

Loveglasses 15 Sep 2015, 22:23

@Robert...Are you just getting adjusted to new glasses or really vision is decreasing enough to make your eyes needing those prescription actually?

Robert S 14 Sep 2015, 22:30

My Rx was R -1.25 -.25 L -1.0 -.50 In March I went with a pair of R-3.50 -25 L 3.25 -.50 glasses. It took me about 3 weeks to get used to them where I could see far crystal clear and about 2 more weeks where I could read up close with them. I started just watching TV with them at night with no light for about a week. I commute on my bicycle and started to wear them on my commutes after that. 3 weeks in I was driving with them on. As of now I can read the smallest print on the near vision eye chart at 16in with them. I later bought a -5.0 -4.75, -6. -5.75, and a -8.0 -7.75 pair about 10 weeks later when zenni had a promotion. And did the same deal with those. It took a bit longer to read up close with them but its doable. I can kind of read with the -6 pair (getting better every week) and I can drive with the -8 in the day time. I take the -5 pair to work. I guess its working with out my glasses on text gets blurry at 8in or so which would put me in the -4ish range. I am almost 36 years old btw.

Hello all.

I am new here.

I was thinking only i have this glasses fetish till i see this website.

Is it really possible to induce myopia?

I already need -1.5 and -2 glasses.

If i start wearing a slightly increased prescription will my eyes will be adjusted to it? How many days will it take?

I am planning to add -0.5 extra to each eyes without changing other values in prescription card like cylinder,axis etc..

Will my eye will adjust to that soon?

Or will i get heavy eye pain?

Cactus Jack 14 Sep 2015, 10:11


Just a note to thank you for for your persistence and the quality of your research. Often, discovering what does not work can lead to a better understanding of a mysterious process. Theories abound, but there is little PROOF. The development of myopia is one of them.

Age and Genes seem to play a big role in the development of Axial Myopia and the fact that there are two types of Myopia, with apparently different causes, that yield the same optical results, makes it just that much more "Interesting" and Challenging. Your genes are in the "Drivers" seat and once a growth function turns OFF, we don't know how to turn it on again. The development of Vision in an individual seems to be an incredibly complex and dynamic process that is very close to the miracle of life itself.


Chino 14 Sep 2015, 09:13

Good news!

I received the information on the optical characteristics for lens filter 90 from Noir Medical. The lens I was thinking of replacing it with is ARG from NoIR Laser. I am happy to report that the optical characteristics between the lenses are different enough to warrant further experimentation.

Based on the %T characteristics of filter 90 and the relative spectral response of human M cones, that particular filter went above and beyond just blocking blue and green light. It almost totally prevented the M cones from responding at all to the light that I was seeing.

The new filter I will try, ARG, is pretty much ideal for this experiment. It really is damn near perfect.

I'm working off the assumption that stimulation of the cones is of primary importance, given that cones respond to light over a range of frequencies. I could be wrong about this. There is the very real possibility that simply blocking blue light is enough, even if the S cones are still being stimulated by longer wavelengths of light such as green.

If my experiment with filter ARG does not work, I will need to find a filter that blocks light at higher frequencies, allowing more green light to pass through. I'll cross that bridge if I get there.

Chino 12 Sep 2015, 10:12

Hi everyone,

Sorry it has taken me so long to get back to everyone. I have an update on the experiment. Unfortunately, it did not work at all.

I've been intensely going over this article, as I think it has the most useful information for this experiment:

As I had mentioned in a previous post, the research seems to indicate that both green and red light are needed for this to work...that previous experiments in which eyes were exposed to only red light had no effect on myopia.

From the researchers' hypothesis, I get the impression that it doesn't need to be perfect. As long as I'm stimulating the L and M cones and not stimulating the S cones, it should work. Given the emission spectrum and percentage of green light (10%) emitted by the red LED, I did some digging and think that I may have found an excellent lens material with the necessary optical characteristics.

I'm waiting to hear back from the company I bought my most recent filter lens through. I requested information on the optical characteristics of that lens including: optical density (OD) values and ranges for that lens, visible light transmission (VLT) and ranges, and a graph of both OD and VLT.

Hopefully, the optical characteristics of my current lens and the lens I found online are different enough to warrant experimentation. If their properties are too similar, I just don't see how trying the new lens would make a difference. I'll keep everyone posted as I learn more.

Soundmanpt 10 Sep 2015, 17:09


I tend to agree with "Cactus Jack" that what your wanting to do could lead to you looking for a new wife if she ever finds out.

But I doubt that your going to find an optometrist that would even consider writing her a prescription that is even a little bit more than she needs and certainly not by more than double her real prescription. If for any reason she were to go another optometrist shortly after getting her glasses and they were to examine her eyes and find that she is so much over prescribed it could lead to a mal practice suit against the first doctor and he or she would lose his or her license to practice.

I think if you really want her to wear stronger glasses than she needs the only way you can do it is by talking her into doing it. You might have a chance if you: a) pay for her glasses and b) don't go over board, her eyes are probably very capable of seeing just fine with -1.25 glasses which is a decent amount more than what she needs but she should be able to see very well with them. If you try and have her wear -1.75 glasses they are going to be too strong for her eyes and if her eyes aren't comfortable wearing the glasses then you failed. The key is very simple don't go too strong and let her pick out glasses on line that your welling to pay for and you both might be happy. Maybe even throw something else in to sweeten the deal with her like a new dress or new shoes or something she wants. I(n other wordds your better off bribing her than a doctor.

Cactus Jack 10 Sep 2015, 15:49


Three questions about your wife:

1. What is your wife's age?

2. How long have you been married?

3. How much longer do think you will be married to this woman if you do something like this?

four questions about you.

1. What is your age?

2. Do you presently wear glasses?

3. What is your prescription?

4. What would you think if your wife changed your prescription without consulting you?


plshelp 10 Sep 2015, 15:10

@soundmap...if i bribe a eye glasses sop guy from where eye test can be done. if we give additional -1(making it -1.75) will she adjust to that in a few days.. or will she find it?

Soundmanpt 10 Sep 2015, 11:38


The problem is if she already has glasses that are -.75 even increasing it to -1.00 she would notice the difference. Now if these are going to be her first glasses and she doesn't have any glasses now then you can probably get away with ordering her glasses on line and even going to as much as -1.25 without her knowing any better. However most optometrist send out reminder cards after about 11 months telling the patient that they are due to get their eyes examined the following month. The first thing they will do is take your wifes glasses and check the prescription and how will she be able to explain the difference between what her prescription was when she last had her eyes checked until now?

So maybe someone else has an idea but I can't see anyway you can do it without her knowledge.

plshelp 10 Sep 2015, 09:44

My wife needs -.75 glasses..can any one suggest me an idea to slowly increase her myopia atleast up to -3?

(without her knowledge ofcourse)

Soundmanpt 09 Sep 2015, 09:57


Yeah sadly I think your well past the age where you can induce any myopia. Once your past 20 it starts to get much harder to induce. But look at it this way your wearing glasses -1.50 stronger than your actual prescription and just slightly under the -4.00 level you would have been satisfied with. I'm not sure if your eyes can tolerate an additional -.50 to that or not? I guess you could always order some glasses on line and see how they work. That would put you at -4.25 / -4.00 not counting your astigmatisms. But just because your able to see the eye chart with weaker glasses, so what the main thing your wanting is the look of your glasses and they should look pretty strong even now.

Cactus Jack 08 Sep 2015, 20:51


Unfortunately, that is the way it works. It won't be very long until Presbyopia will start limiting your ability to wear over correction so enjoy it while you can. However, there is another option that works at any age, GOC.

If you can comfortably wear contacts, we can teach you how to be as myopic as you wish with the proper GOC combination. Comfortable and effective GOC requires careful planning and willingness to follow some simple rules that have beed developed by experience. If you are interested, post your most recent complete actual Glasses Prescription on the GOC thread and if you have one your complete Contact Lens brand and prescription.


luvspecs 08 Sep 2015, 13:52

Hi Guys

Thought I would share my experiences of trying to increase my myopia. I have wanted to need thicker glasses ever since the day I got my first pair at age 20. I had waiting far too long to get glasses as I remember struggling to read the boards at school at around 13/14. I was probably around 24/25 when i discovered this site, and after reading the many posts on the subject I decided to start wearing glasses with an extra -1.50 in each eye (RE -3.75, LE -3.25). Sadly for me my RX pretty much stayed the same so I gave myself another increase. I have been wearing glasses with an extra -2.50 in each eye for the last 4/5 years, still unsuccessful in increasing my true RX. I'm now 35 and don't think I will ever get the increase I would like(it would have been amazing to get -7 or higher but -4 or -5 would have been a great result). My real RX is still more or less the same (RE -2.50, -1.00 LE -2.25, -1.00) as it was at around 24. Good Luck to anyone who is currently trying.

Chino 03 Jul 2015, 15:12

Excellent news! The red filter lenses from NoIR arrived today and I must say, I am not all. The sales rep was not kidding. These really do block everything except red. I looked at my bright blue duffel bag, and it looks completely black. It really is monochromatic vision. Everything is shades of red.

Those red tinted lenses form optical4less did nothing for me. I did not notice any change in my eyesight. Today is the proper start of this experiment.

As I mentioned in my last post, green light may also be necessary for this experiment to work. I will use these filter lenses for the next two months. If I don't see any results, I'll purchase the multi-lens laser filter that I mentioned previously. Wish me luck!

Chino 23 Jun 2015, 20:06

I never heard back from Phillips Safety, but did receive a prompt response from NoIR Medical Technologies. They assured me that their red lenses will block everything except red light.

The salesperson made a couple lens recommendations and helped me pick a good fitover frame. She also told me that, if I wasn't satisfied with that particular lens, I could exchange mine for another pair with a different lens. Overall, I was very pleased with the experience.

I went ahead and ordered them this morning. Hopefully, those will do the trick. I ordered lens filter #90 with fitover frame #53. It wound up being cheaper than the goggles I bought from optical4less, and that was before the folks at NoIR Medical gave me a 20% discount on top of that :).

I really hope this does the trick. If I still see blue light, I may try lens #93. That one has very low visible light transmission, and would probably be very difficult to use indoors.

If these goggles do not induce myopia, I have one more option that I can try. The researchers in this journal article: have a hypothesis as to how myopia is induced. It looks like some green light may also be necessary to make this work. If this is the case, then I'll need a filter that will block blue light, but allow both green and red light to pass through. It may also work if yellow and orange light pass through as well. The red LED that they used also emitted light in the green, yellow, and orange wavelengths.

I have to keep in mind that, while this experiment may work if the eyes are exposed to yellow and orange light, there is the possiblity that these other wavelengths could slow myopia progression. In the experiment, the blue LED also emitted green light, but did not emit yellow or orange light. This might be the reason why hyperopia was induced at a faster rate than myopia.

If it becomes necessary to also allow green light to reach my eyes, I will need to purchase filter lenses from NoIR LaserShields instead. I would purchase filter lens ARG. This filter blocks all blue light and some green light, but still allows the longer green wavelengths to pass through. I would use this lens with frame #40 because it has a flip-down secondary filter. I would use filter DYE as the secondary filter. DYE provides good absorption for 70% of yellow wavelengths and 33% of orange wavelengths without blocking red light.

This setup would allow me to adjust the wavelengths that my eyes are exposed to. If even this setup doesn't induce myopia, then I would consider the experiment a failure.

I'll keep wearing my red goggles from optical4less until the new filters arrive. I'm almost a week into the experiment, and have not noticed any change in my eyesight. I'll post an update when I get those filters.

Likelenses 21 Jun 2015, 23:19


Interesting term used in this report,that I had not heard before,Myopic Creep.

Danbert 20 Jun 2015, 02:24

Anyone thought about or investigated anything along these lines?

According to one (limited) study the use of soft contact lenses may be correlated with myopic shift.

Chino 19 Jun 2015, 16:22

Hi everyone, thank you for the suggestions. The colored gel that Cactus Jack suggested could be a good low-cost option.

I've been doing some more digging and think that a specialty multi-spectrum filter lens may work. There's an eye condition called achromatopsia that's caused by having little to no cones in the retina. As a result, people with this condition see with their rods instead. They have little to no color vision, and are very photosensitive, frequently experiencing day blindness.

People with achromatopsia tend to do well with lenses that allow primarily red light through because, since the retina is least sensitive to red light, red light is less likely to saturate their rods.

I've found a couple places that might do the trick. One vendor specializes in low-vision eyewear for people with various eye conditions including achromatopsia. The other site specializes in eyewear for people who work with lasers or perform welding.

Here are the links:

I'm going to ask them some questions via email and see which of their products would work best for this experiment. I'll keep everyone posted.

In the meantime, I'll keep wearing the goggles and hoping for the best.

Cactus Jack 19 Jun 2015, 15:33


We need to talk about what prescription numbers mean from a vision point of view. The idea that you don't need to wear vision correction until your prescription reaches a certain point is ridiculous. If you apply the laws of optical physics, discovered and codified by Sir Isaac Newton over 300 years ago, even a prescription of -0.25 means that vision beyond 4 meters or 13 feet is fuzzy. -1.00 means things get blurry beyond 1 meter or a little over 3 feet. -2.00 means 0.5 meters or less than 20 inches. If any astigmatism is present, that just makes it worse.

No one, even an Eye Care Professional (ECP) actually knows how YOU see. That is why there are two parts to an eye exam. The Objective part where the ECP looks into your eyes with a machine or optical instruments to estimate your prescription. The Subjective part is where the ECP uses trial lenses and you tell him what YOU see. The Subjective part depends on your skill in describing what you see of accuracy.

You need to get it through your head that you do not wear glasses for the benefit of other people, except in one instance. Driving! You need to see well enough so you are not a danger to others on the road.

After that, how well you see and how comfortable your vision is strictly up to you. Think of glasses as simply tools to help you see better. Nothing more and nothing less. Carefully chosen frames can enhance your appearance. Poorly selected frames can degrade your appearance. Think of the very basic reason you wear clothes or shoes. Fundamentally, clothes provide protection from heat and cold. Everything else is secondary. You wear shoes to protect your feet from sharp stones. Everything else is secondary.

We can help you get the glasses you want, but there are some limitations. You mentioned close focusing problems with the -2.50/-3.00 glasses were causing problems. What is your age? It is important.

You did not mention your gender. That is important also.

Where you live is also important because of cultural differences.

As far as Excuses go, you really don't need one. The fact that YOU see better or more comfortably with your glasses than without, is all that is needed. Period!


Excuse 19 Jun 2015, 12:27

Sorry, should have said that I've posted here before. Was advised previously not start too strong above actual RX of -0.5/-1 (with some astigmatism) but I went ahead and got -2.5/-3. SO I should have taken that advice!

Anyway, nobody really knew I had glasses before - I barely wore them for 10 years because the optician said I didn't really need them and so whenever I put them on and people commented I'd get nervous that they would think they were not strong and ask why I was wearing them.

The -2.5/-3 was too strong. I did get used to them in a day or 2 and saw absolutely clearly (better than 20/20) but up close was a little difficult for very small text.

I want to go -1.5/-2 now as I want to get used to the first and try -2.5/-3 later. I am having such anxiety about people commenting. The whole fashion trend of glasses makes people (especially those with glasses) become suspicious of (even though anyone trying on the -3s was shocked at how strong they were).

Maybe it is just my personality but the comments about me "suddenly" wearing glasses really make me nervous. I have been "struggling" to see things sometimes but other times I have been forgetting. I am not planting the seeds very well.

"I usually wear contact lenses" will not be a good excuse as recently I have had a friend and a colleague have some medical emergencies with split contact lenses and contacts were a topic of discussion (and people know now I don't wear them). I have noticed on Facebook some people suddenly wearing glasses though that look quite weak but they did start wearing them Late 20s.

What are viable reasons? I'm guessing non OOs (even glasses wearers) are not that clued in. Can I give headaches? Police questioning lack of glasses when pulled over? Declining eyesight after years of getting away with never wearing my glasses - "it must be all the computer use at work"?

Cactus Jack 18 Jun 2015, 17:06


How about telling us a bit more about yourself. Things such as your actual prescription, the prescription you want to wear, where you live, your gender, and your occupation.

While most people discover that they need glasses in childhood or in their teens, it is not unusual for people to discover that they need glasses in their 20s or even 30s. Frankly, you don't really need an excuse to see well, but I think we can help. Many of us have been there and done that.

BTW, most people don't notice lens changes unless they are very different and obviously so. What they notice are the frames. If you keep the same or very similar frame styles, you can generally over correct to your hearts content, without comment.

If you don't know how, we can even help you order inexpensive glasses, in the prescription you want, on line.


Excuse 18 Jun 2015, 16:34

Hey, I am really struggling with the reactions of friends and family when trying to become full time (overcorrecting, late 20s, nobody knows I "need" them). And colleagues too. Any advice?

Cactus Jack 17 Jun 2015, 18:37


I really don't know. I have never worn heavily tinted glasses, other than green, brown, or gray sunglasses. Many years ago, it was common to wear Red lensed glasses to preserve night vision or low light vision. They were often worn by aviators who were to fly night missions during WW 2. In the 1960s, before image intensifiers were invented, Radiologists used them to condition their eyes for viewing a Fluoroscope screen for certain types of X-Ray exams. The lenses had Red colored glass. With the exception of Transition type lenses, most tinted lenses today are made of clear plastic which is then submerged in a dye solution that penetrates the plastic. I suspect that it is not very good at blocking all different colors. Here are a couple of suggestions:

1. Check out the highest percentage Red Tint Zenni will do and the cost. Consider getting a pair.

2. Consider getting some "Colored Gel" that is used for stage lighting. It is typically available in many different colors. It is pretty rugged and is designed to withstand high heat from strong incandescent lights. You should be able to figure out how to use the gel film on clear lens glasses or to cover room lights. You need to block ANY light reaching your eyes around the red lenses. You may be able to find Black "Temple Shields" that fit on your glasses temples.

3. Investigate RED LED lights. LEDs produce only one wave length of light is it monochromatic. If you pass it through a prism, it will produce only a narrow RED line with no other colors, apparent.

4. Check out stores or museums that have WW 2 Aviation Memorabilia. They might have some Red Aviators Goggles with glass lenses. England flew mostly night bombing missions during WW 2 because the bombsights you had were not very precise and night bombing raids were not intended to be very precise. With very rare exception, Europe was blacked out and targets were very hard to find using star light or moonlight. The Americans had a Top Secret, very precise, Norden Bombsight and did Daylight Precision Bombing and did not need to wear Red lensed goggles to prepare for a mission.


Chino 17 Jun 2015, 14:07

The experiment is active, but I am skeptical about the goggles.

I don't think the tinted lenses method is going to work. I've been walking around with the goggles on for a couple of hours now, and have noticed that I can still see other colors through the lenses. Even worse, I can still see blue light through the lenses.

I have a bright blue duffel bag, and I can see that it is very obviously blue...plain as day.

Cactus Jack, are lens tinting techniques pretty standard among vendors? Do you think it would be worth it to try some tinted glasses from zenni instead?

Chino 17 Jun 2015, 03:59


No problem there. I have a personal interest in finding a method that works. I have no desire to mislead people with an ineffective method. Having said that, we need to keep in mind that, even if it doesn't work for me, there is still the possibility that it may work for younger members whose eyes are still growing. If the experiment fails, it would be up to younger members to try the experiment and see if it works for them.

Just a quick update. The experiment begins later today. My red goggles arrived at my post office and will be out for delivery this morning. Wish me luck!

onihc 16 Jun 2015, 01:01


In this experiment, be sure to lay down the facts. Don't tell people that something works if it doesn't. This could be revolutionary for inducing myopia so be sure to keep it honest.

Chino 15 Jun 2015, 17:05

I received my red strobe today, and am using it as I type this. It pretty much does what I need it to do, but the electrical cord for it is very short, so it's a challenge to set it up comfortably. I'm going to need an extension cord for it.

The red goggles are still in transit from New Hampshire. It probably won't make it down to me until the end of the week.

Chino 11 Jun 2015, 15:31

I ordered a red strobe today, and it actually shipped earlier this afternoon. I estimate that I should receive my goggles and the strobe light around the same time, early next week.

I bought the red strobe to see if I could boost the effectiveness of the red goggles. According to one of the research papers I posted earlier, the guinea pigs exposed to flashing red light became more myopic by -11.29 diopters over the course of 8 weeks, or about -1.41 diopters per week. That's about -5.64 diopters per month, which is more than the -3 diopters induced by steady red light.

Chino 04 Jun 2015, 10:28

Just a quick update. They finished making my goggles sooner than I expected. They shipped the goggles today, so I should be able to start this experiment with the red lenses in about 10 days.

Cactus Jack 02 Jun 2015, 19:44


Yes, please.

I will try and take a picture with a prism in front of the camera lens. Have no idea what will happen, but it will be fun to try. I suspect the separation will be apparent. Camera lenses are designed to minimize chromatic aberration, but I think I have a loose 10 D prism that I can hold over the camera lens.

I'll keep you posted.


Chino 02 Jun 2015, 14:47

Cactus Jack,

Yes, I downloaded the whole article. Would you like me to email you a copy?

Man, that effect with the prism lenses and LED based signs is something else. I wonder if I can find a picture of that effect somewhere.

optix 02 Jun 2015, 10:58

the most extreme example in everydays life is this sign.

No parking, here in Europe.

See this one throgh prism lenses and you will know...

Cactus Jack 02 Jun 2015, 10:02


Did you download the whole article?

Lenses and Vision are fascinating. You can think of a lens as being an infinite number of very thin prisms arranged in a circle. Negative lenses have the apex of the prism in the center and the base at the edges. Plus lenses have the apex at the edge and the base in the center.

Chromatic abberation and its prevention is the basis of high quality multi-element photographic lenses. They use a combination of Negative and Positive lenses to combat it.

Chromatic separation of images is really interesting if you need to wear prism. I wear Base Out prism and if the lighting is right, I see color fringing with each eye individually, but with both eyes together, my brain seems to cancel it out. Another extremely interesting effect occurs with LED based signs. LEDs produce monochromatic light. Yellow is actually created by a RED and a GREEN LED, very close to each other. The eye normally perceives this as YELLOW. However, with the prism in my glasses, the prism separates and displaces the two colors by by different amounts and I see slightly separated RED and GREEN letters instead of one YELLOW. Light from incandescent or phosphors sources do not exhibit this phenomena.


Chino 02 Jun 2015, 08:11

Hi Cactus Jack,

I enjoyed reading your explanation on the chromatic aberration of the eye. Given how different wavelengths of light are refracted at different angles by the same lens, your explanation makes total sense to me. I got curious and started doing some digging.

I found research that addressed this very question. The researchers found that positive lenses did not suppress the effects of red light. Negative lenses did not suppress the effects of blue light.

Given what you told me, the lenses they used should have compensated for the chromatic aberration, so that the eye's lens would not have to. What they did should have prevented the changes in eye shape induced by the different colors of light used.

Since the lenses didn't work as they were supposed to, I'm starting to get the impression that we may be working with a different mechanism here. Optical4less is still crafting my goggles, so it'll probably be another three weeks before I get to experiment for myself.

Here is the article:

Cactus Jack

Thank you for the explanation, sounds like a valid reason for my girlfriend to explain what I'm doing;-)

Cactus Jack 26 May 2015, 19:08


Keeping your Ciliary Muscles strong can delay the practical onset of Presbyopia. As your Crystalline Lenses gradually become stiffer, they become harder for the Ciliary Muscles to squeeze to increase their PLUS power. When you wear the -4 contacts, your Ciliary Muscles have to create a compensating +4 for distance and between +6.50 to +7.25 to focus close. The will likely help you maintain your accommodation range.

You often see the opposite effect when people with low to moderate myopia don't wear glasses and their Ciliary Muscles don't get much exercise. In general, exercise is good for any muscle, but Presbyopia will ultimately win. Typically, when a person's arms get too short and the start wearing reading help. Ciliary Muscle de-conditioning will happen much faster than they expected until the Add reaches their preferred focal distance for reading. Usually, somewhere between +2.50 and +3.25.

An unexpected symptom of the onset of Presbyopia is a decrease in the relaxation rate for your Crystalline Lenses or Pseudo Myopia and you will start to notice blurry distance vision when you take the contacts out in the evening. You probably have quite a few years before that occurs.


til 26 May 2015, 00:34

Cactus Jack

I'm 27, m, live in Germany.

It is not my goal to induce pseudo myopia, I would only accept it. I cannot really explain my motivation for wearing overcorrection, I simply like to wear 'proper' glasses and like the look of concave lenses on others. So at the moment I am only trying to push my limits by wearing -4 contacts or -6 glasses.

Concerning the ciliary muscles I rather was wondering if that 'training' could prolong flexibility of the muscles and crystalline lenses. In order to push the point of needing correction for reading maybe?


Cactus Jack 25 May 2015, 13:48


I think the use of the red lenses to try to induce myopia is an effort to take advantage of the chromatic aberration of the eye. It is a variation, of sorts, on the Red-Green Test.

The Red-Green test is often used as a final test for sphere correction. The optics of the eye focus Green light slightly in front of the retina and Red light slightly behind the retina. In the Red-Green Test, if Red is clearer, -0.25 is added. If Green is clearer +0.25 is added. If both are equally clear, the Sphere correction is pretty close to optimal.

Why the use of red light might help induce some myopia needs some thinking about how the optics of the eye and glasses or contacts work. The key thing to remember is that glasses or contacts neutralize or cancel out refractive errors. If a person is myopic and needs to wear MINUS glasses, it is because their eyeballs have TOO MUCH PLUS. If the person needs PLUS glasses it is because their eyeballs don't have ENOUGH PLUS to focus images on the retina.

If you wear glasses with Red lenses, the image will be focused BEHIND the retina and your ciliary muscles and crystalline lenses will internally add some PLUS to move the image into focus on the retina. This is the same thing that occurs when you wear glasses with a bit too much MINUS.

If you do either of the above, it is possible that you will Induce some Pseudo Myopia, if your ciliary muscles and crystalline lenses can add the necessary PLUS for long enough. If you are young enough, you might be able to Induce some Axial Myopia.

The big question is which is faster or more effective. Red Lenses or more MINUS in your glasses than you actually need. We look forward to your report.


Cactus Jack 25 May 2015, 13:05


Genes are always in the driver's seat. People with low hyperopia frequently have experiences similar to yours. However, sometimes it is possible to induce some Pseudo Myopia. That is not always successful as we have seen where a person develops "buyer's remorse" after Lasik and wants to be myopic again.


The ciliary muscles are the strongest muscles in the body for their size and they respond to exercise and can temporarily adapt to over correction by being slow to relax. Pseudo Myopia and Latent Hyperopia are actually the same thing. The real difference is that even a hyperopic young person with extremely flexible crystalline lenses can develop Latent Hyperopia if their hyperopia is uncorrected. Their ciliary muscles become so used to maintaining the extra PLUS, every waking hour, for every visual task, that they are unable to fully relax their ciliary muscles. When they finally get some external PLUS correction, it can take a while for their ciliary muscles to finally start relaxing. When that happens, they will need more external PLUS until the ciliary muscles are fully relaxed. The teen age (now 17) son of a friend had to get some low PLUS glasses with a bit of cylinder, for full time wear, about a year ago because of headaches. I saw him about 3 months ago, and I noticed that he had a bit more PLUS in his glasses. I suspect he has a bit more PLUS in his future. Obviously, he had developed Hyperopia at a fairly early age, but it remained hidden until creeping Presbyopia and smartphone exposed the problem.

Age can be a factor in Pseudo Myopia. It is possible that wearing the -4 contacts may be counter productive in developing Pseudo Myopia by triggering a strong focus and relaxation response. The exercise keeps the ciliary muscles and crystalline lenses very flexible. If you want to Induce some Pseudo Myopia, you might actually do better with lower power contacts or possibly multi-focal glasses that pretty much let your ciliary muscles maintain a constant power level.

May I ask your age?


Chino 25 May 2015, 11:40

I'm 33 years old, and my starting prescription is -5.50D in both eyes, with -0.50D of astigmatism. The only difference between my eyes is the axis for my astigmatism correction.

I plan on doing this every day, for at least 14 hours per day.

 25 May 2015, 10:39

Chino, what is your age and starting prescription? Also how often do you plan on doing this? Like how many days and for how long each day?

til 25 May 2015, 09:24

Just a thought on ciliary muscles..

I did quite a bit of driving recently and sometimes wore -4 contacts. I don't require any correction and can tolerate them well. However I have to maintain focus actively and if I don't i will lose focus within a second. My thought now was if it is the same work for the ciliary muscles to maintain focus all the time or do I 'train' them better going from blur to sharp vision multiple times. Does anybody happen to be familiar with this?

Julian 25 May 2015, 08:34

I may have said this before: but I just don't understand this business of inducing myopia. As a kid and right through my teens I did all the things that are supposed to make you short-sighted - I read incessantly, often in a bad light, even by torchlight under the sheets. I got my first glasses when I was 18, and they were low plus with a a bit of cylinder. I reckon heredity rules.

Chino 25 May 2015, 05:57

I am now able to prepare for this red light experiment.

I ordered a pair of prescription sport goggles with red lenses. Hopefully, their design should prevent light from entering through the side of the goggles. This way, my eyes only get exposed to the red light entering through the lenses.

These are the goggles I ordered:

I tried zenni, but didn't find a design that satisfied me. Unfortunately, this means I'll need to wait about a month for my goggles to arrive.

I'll post an update when I receive my goggles and start the experiment.

svensont 18 May 2015, 13:41

Hey Stan, how are you doing? Are you using your +2D glasses?

Chino 15 May 2015, 06:34

You know, that's a great idea. I think that just might work. The red lenses would filter out the other wavelengths, letting only red light through. It's definitely worth a shot.

I don't know how necessary it is for the light to be flashing. I know one study used that, but others have not. Personally, the flashing light would annoy the hell out of me after a while.

 15 May 2015, 03:12

Would this denote wearing red tinted lenses to induce myopia? Or would it only include an actual red light? Id love to rig my room with a flashing red bulb to experiment but i just dont think its plausible.

Chino 12 May 2015, 03:49

Hi everyone,

I read some interesting articles online. It looks like red light can potentially be used to induce myopia.

I'm out of town right now on an extended vacation, and am not able to experiment with this. Would anyone be interested in trying this out and keeping us posted on your results? It would be interesting to see if this works on adults.

Here are the articles:

NJ 07 May 2015, 16:51

oops, post that last comment to the wrong thread.

NJ 07 May 2015, 16:49

CONCERNED, you should have no problems doing GOC after your surgery. I had to wait a couple of weeks before I could insert contact lenses, per the ophthalmologists recommendations. It felt exactly the same as before.

It's possible to alter your numbers to have the vision you want, but not many docs will intentionally give you worse vision. In fact, most will try to fully correct it using either the monovision technique or correct for distance only and you will need readers. I see Specs4ever managed to get his pre-surgical numbers, but he had a pretty good argument for doing so.

If you do find a doc to give you worse vision, please think long and hard about doing this. It's one thing to have bad vision when you want it, quite another to have to live with it all the time. GOC works great for most people here.

Cactus Jack 07 May 2015, 14:34

mo tard,

6 1/2 feet is pretty close to 2 meters. That means that your actual prescription has increased by about -0.50. It could be True or Axial Myopia, but it is more likely Pseudo Myopia. Either one will work, but only time will tell which it is. Keep working at it and pushing the envelope whenever you can.


mo tard 07 May 2015, 10:47


I pinned up the eyechart. Made my 20 ft line. Went back to my official rx glasses and I could not see the 20/20 line. I had to move up to 6 1/2 ft to see the 20/20 lin3

Cactus Jack 07 May 2015, 00:11

mo tard,

Wow! That works out to +6.50 of additional accommodation over that needed to make the -9.25 glasses work. Normal reading would use +2.50 to +3.00 of the +6.50 leaving as much a +3.50 of "free" accommodation that you could use for even stronger glasses. However, there is likely a bit of a snag in that you could probably not maintain that much accommodation for very long periods.

When you were focusing at 6", your eyes were turned inward (converged) the equivalent of approximately 20 prism diopters Base Out in each eye (total 40 diopters). Because of the interconnect between your eye positioning system and your focus control system, the convergence helped you maintain the +6.50. If you tried some -12 glasses, it is likely that you would get pretty tired, pretty fast, but you might be able to work up to 1 or 2 more diopters of MINUS in the glasses.

Also, this is one of those instances where Vertex Distance (VD) may be helping a little. Because of VD effects, -9.25 glasses are about -8.25 at the cornea, where the accommodation is occurring. If you went up to -12.00 VD effects would make it about -10.25 at the cornea, requiring +2.00 of additional accommodation instead of about +2.75 one would expect by just comparing the two glasses prescriptions.


mo tard 06 May 2015, 23:31


I just did that and measured . 6" is as close as I can get and still be able to read clear

Cactus Jack 06 May 2015, 13:12

mo tard,

One test you can do very easily, is to check your accommodation range. With the -9.25 glasses, all you have to do is move a book or newspaper closer to your eyes, until the small text just starts to get fuzzy and measure the distance.

You have used up some of your accommodation to be able to focus at distance (20 feet or 6 meters for practical purposes) with the -9.25 glasses. To focus closer, you need some plus from somewhere. Ideally, it can come from your ciliary muscles and crystalline lenses. Where the text just becomes fuzzy is pretty close to the limit of your accommodation. You can calculate the amount of PLUS required by dividing the distance into 100 cm or 39.37 inches, depending on the measurement you prefer.

Lets say that you measured about 28 cm or 11 inches, did the math above, and got +3.50. That would mean that you still had that much accommodation remaining. If you like to read at about 16 inches, you could probably tolerate about -10 in your glasses and still be able to focus to read with some effort.

However, don't expect that ability to last very long. Presbyopia never stops until your crystalline lenses get so stiff that your ciliary muscles can't squeeze them more. Wearing over correction may actually help keep your ciliary muscles strong, but that is ultimately of very limited value.


mo tard 06 May 2015, 02:55


I did try my original rx. I didn't pay particular attention to distances but do notice there is a definite blur at distance. The -9.25 glasses arrived Monday been wearing them right from the mail box. I did notice a defined increase in focus effort again. However it seams to be short lived as within the first day focusing came easier and now more natural with out thought. The lens edge is definitely thicker and nobody has noticed the extra or at least not questioned it if they did I'll see if I can come up with some more definite numbers on blur distance with original rx in next couple days.

Also on side note I can still see up close for reading with the -9.25.

I'm getting curious how far I can push up rx before maxing out my accommodation or getting called out on the lens thickness

Cactus Jack 30 Apr 2015, 07:19

mo tard,

Thanks for the refresher. I really appreciate that courtesy. There is just no way I can keep track of everyone and age, gender, and where you live, does help me compose answers that fit your situation.

I suspect that most of your results are related to Pseudo Myopia because of your age. The fact that you find yourself pushing the -8.00 glasses closer to your face to see clearly is particularly interesting, because Pseudo Myopia seems to require long term focusing stress to cause the Ciliary Muscles to increase the PLUS power of the Crystalline Lenses. Axial Myopia increases usually are caused by a growth process where age and genetics are a big factor. Age seems to play a role in Inducing Pseudo Myopia. This is because Presbyopia stiffens the Crystalline Lenses and makes them more difficult for the Ciliary Muscles to squeeze and increase their PLUS power. The stiffness also makes the Crystalline Lenses MUCH slower to relax.

An interesting test would be to try your original Rx just after waking from a good night's rest to get an idea of the distance where text just begins to get fuzzy with your glasses. That would give you an idea of what you could expect from an eye exam.

If you are really curious about your increase, you may want to consider an exam by a different ECP than the one where you got the -6.75 Rx. It is unfortunate that the ultra sound instruments that Ophthalmologists use to measure eye ball length are not more common. Making physical measurements over time are the best way to determine the source of prescription changes over time and differentiate between Axial Myopia and Pseudo Myopia. At your age, significant increases in Myopia in even a years time, is not very common unless it is Pseudo Myopia. Remember, Pseudo Myopia and Latent Hyperopia are the same thing, only the basic cause of the refractive error (eyeball length or total relaxed lens power) is different.


mo tard 30 Apr 2015, 04:13

Hey everyone. Been a while since I posted. I've been working on trying to increase my myopia. My last official rx (Aug 2014) is R -6.75 -2.00 20 / L -5.50 -2.00 170. I have been wearing zennis (since Oct 2014) in rx R -8.00 -2.00 20 / L-6.75 -2.00 170. At first I noticed awesome vision with increased effort to focus. Recently I have noticed I don't have to try to focus anymore and I find myself pushing them tighter on my face to see in distance. So a couple days ago I GOC with extra -2.00 in contacts with my glasses. The first few hours took some time and real effort to see clear. After a couple days it became easier to wear that combo. So I went and ordered identical frames I'm currently wearing in rx R -9.25 -2.00 20 / L -8.00 -2.00 170. I went with the -1.25 jump again because no one seamed to notice the first -1.25 jump on top of my official rx. Can't wait to get them and wear them for 3 or more months before next eye exam. For the exam I will swap back to the original rx just before going in the door and see if there is upward progression in my rx.

There is not much reason to frown on what you are doing many members have experimented with found contact lenses. Some with more success than others. We can help you be successful.

Disposable Soft Contact Lenses are very forgiving from a fitting standpoint because they are usually very thin. With your GOC experience, you probably know how to insert and remove contact lenses. Please exercise good hygiene and lens care for your own eye safety.

You seem to understand a bit about the optics of vision, but you probably need a bit of a refresher. I am guessing that you are older than 20 and younger than 40, but a guess does not help much in helping answering your questions. I need a bit more specific answers about the following to offer suggestions and guidance.

Here are the questions:

1. How old are you?

2. Where do you live? Country and region would be helpful

3. Your occupation appears to be in flat management. Is this correct?

4. What is the Brand and Model of the -3.00 lenses?

5. There should be more information on the box, such as Diameter, Base Curve, and wear information. Are they designed for Daily wear, Weekly wear, or monthly wear?

After you answer the above questions, I will probably have a few more.

Again, Welcome.


mark 23 Apr 2015, 03:45

I know it will be frowned upon by various users here as to what I'm currently doing, but there you go!

Someone moved out of one of my flats yesterday and whilst I was sorting it out to relet I found a pair of disposable -3.00 contact lenses behind the bedside cabinet. I don't wear correction, but have thought I have quite a tolerance to weakish minus prescriptions from previous experience or wearing glasses out and about, and doing a little GOCing years ago. So today I decided to wear these contact lenses to work and see what it would be like.

I'm amazed at how well my eyes have coped with it, with my vision being pretty much the same as it normally is, in terms of day to day viewing aside from reading text - like typing this, the words aren't as crystal clear as they normally are, but I was expecting to either see a dramatic difference, and everything to be more clear than it normally is and therefore think maybe I need glasses, or on the other hand think, why on earth am doing this!

I have experimented a little with the blurry text on the computer screen as I have an office to myself so no one seems me apart from when they walk past, so decided to do a little GOCing, and remove the glasses when people walk past. So I have a pair of plussie glasses that I bought on ebay - I like the frame, and thought the missus would look good in them (they're a unisex horn rimmed frame) - plus she wears +1.5 reading glasses, so they'll come in handy for that. I have found that wearing the contact lenses, the keys on the keyboard are clear, but the text on the screen is a little blurry, but when I put the glasses on, the opposite happens, where the text on the screen sharpens up a lot, but the keys on the keyboard are rather magnified

The only problem with this is that whenever I take the glasses off its takes my eyes a few moments / half a minute to refocus!! Interesting stuff when colleagues are coming into my office asking questions and I can barely focus on them!

I really was expecting a bit more of a blur with the lenses in, but it would seem my eyes want stronger contact lenses in order for this to happen. What would one of the more regulars advise to wear in for this to happen?

Stan 21 Apr 2015, 10:13

Maybe try some +0.5D on top, if you can see clearly the distance then you can order some progressives.

That would be more complicated as I would have to order them on line. When I looked in the distance with the +1.00's (weakest I could find) everything was pretty much a blur.

Did you notice any change in distance clarity when looking through +2D now and a month ago?

No, both are too blurry for distance, that is why I got the plano top bifocal...couldn't wear the readers because of the distance blur.


svensont 20 Apr 2015, 08:31

Stan 20 Apr 2015, 07:08

So I went to Walgreens here and tried some +2's and then bought them. The distance blur is much worse, but if I hold print a bit closer it is bigger and has more contrast than with the 1.50's. I HAD to go back and get another pair with the plano tops because I couldn't wear the readers for anything but reading. Seems I feel more strain with the + 2's After I wear them a bit and check my close without them there is certainly more blur than there was when I took off the 1.50's. I'll try these for a bit to see how well I adjust to them. Am I on the right path?

Thanks. There are actually 4 lenses in your eyes lens system. Three of the lenses are fixed power (Cornea) or semi-fixed power (the Humors) and one is variable focus (the Crystalline Lenses), which with your Ciliary Muscles, are the Auto-Focus system in your eyes. If have "normal" vision (0.00 refractive error) for distance, the total power of your 4 lenses is around +58 diopters that is needed to focus distant images on your retina which is about 17 mm from the back of your crystalline lenses.

To focus at closers distances, the laws of optical physics dictate that you will need some additional PLUS. The actual amount can be calculated by dividing 100 cm or 39.37 inches by the distance to what you eyes are trying focus on. For example, if you like to read at 40 cm or 16 inches you will need an additional +2.50 to focus at that distance. To focus closer, you will need more than the +2.50. To focus farther away you will need less than +2.50. The exact amount you need at any particular time is determined by your focus control center and it causes your Ciliary Muscles to squeeze the Crystalline Lenses and focus the close image.

It actually does not mater where the +2.50 you need to focus to read comes from. It can all or partially come from external lenses or from your internal Crystalline Lenses just so the total is +2.50. The +1.50 is ideal for focusing on computer displays at 66 cm or 26 inches, but if you want to read at say 33 cm or 13 inches your Crystalline Lenses will need to add the extra +1.50 for a total of +3.00.

The point of the above is that you may want to consider a bit more PLUS in the ADD for your glasses to be more effective or even consider ordering progressives from an online retailer such as Zenni.


Stan 16 Apr 2015, 07:41

Plane on top, +1.50 for reading.


Cactus Jack 15 Apr 2015, 06:51


You can't rush this process, so keep on wearing your glasses full time.. Based on what you wrote about noticing the improved contrast and easier text reading with your glasses, you are having to work harder to focus on small text, and find it better to move it farther away from you without your glasses, means that your efforts are having effect.

Could you provide the specifications for the ADD in the glasses?


Stan 15 Apr 2015, 00:50

An update on wearing my new glasses. I took a trip for about a week, and except for sleeping never took them off. Anything close was great and easy to read. I can still easily read without them, but print, like newspaper, is certainly not as bold and crisp. I have to concentrate a bit more and hold very small print a bit further away. Time yet for an exam?

Soundmanpt 14 Apr 2015, 07:42


If your eyes weren't already stable then wearing even just -2.00 or weaker would have induced myopia in just a few months of constant wear. It's not about the strength of your glasses that is going to create myopia but more about your age and being sure to wear your glasses every minute your eyes are open. Going stronger is fine but I fear all that is going to happen is that your eyes are going to be very uncomfortable.

Campesino 13 Apr 2015, 19:06

Good notice my friend, i will keep trying. Im Jump to -6,0 each eye right now. And wow it been hard to use 24h per day. Is there diference to use like -2,0 or -3,0 or -6,0 , or even -10,00 for example to try to induce.? These older people that have sucess usei to use low or highter minus power?


Soundmanpt 07 Apr 2015, 08:26


Yes there are probably quite a few that have managed to induce myopia even into their 30's but for most it becomes harder and harder once your in your 20's. The prescription your wearing is more than strong enough to induce myopia if your eyes were willing to be changed, but if you still have perfect vision after wearing those glasses for more than a year going stronger isn't going to do any good either.

You may just need to accept the idea of wearing your glasses as if you need them and be happy with that. Just remember that your the only one that knows you don't really need your glasses anyway.

BritishSpecs 07 Apr 2015, 08:16

Just received my stronger glasses this morning. Took about an hour to get used to focusing with them, but now I have no issues with close up or distant vision. Already wanting to go stronger, it's an addition!

Campesino 06 Apr 2015, 18:19

Thanks folks, im have 0 myopia. Actually Im will leo trying

Do you know anyone here able to induce any amount of myopia with 20's folks?

Soundmanpt 04 Apr 2015, 07:16


I agree with "Cactus Jack" because your 25 it very possible that your eyes have become stable and are refusing to be be changed. But as long as your eyes are able to tolerate -4.50 glasses and everyone by now must assume that you need your glasses than there really isn't any reason to change anything. Just continue wearing your glasses everyday and your the only one that knows you don't really need your glasses. There have been others with the same complaint and even considering finding a doctor to make their eyes myopic even though like you they were wearing fairly strong glasses with their perfect vision.

Cactus Jack 03 Apr 2015, 15:25


Sounds like your vision has stabilized and it will be difficult to Induce Myopia. However, If you are comfortable with wearing the -4.50 glasses, there is no reason you can't continue.

What is your actual prescription?


Campesino 03 Apr 2015, 14:11

Hey guys im trying inducing myopia for 1 year with glasses strong, -4,5 for example. Well no results at All! Shall I keep trying?

25 years btw, and using glasses 24h per day

Cactus Jack 23 Mar 2015, 09:02


Yes, a little too soon. I suggest planning 2 to 4 weeks. You may begin to notice some effects in two weeks and I will suggest some tests and additional steps, you might consider.

The fact that you forget you are wearing them and like what they are doing for you, is a good sign for achieving your goals.

Have you worn them around your friends and co-workers? Any comments?


Stan 23 Mar 2015, 07:56

Thanks gwgs. I got the clear to bifocals last week and really like them. When I look through the top everything is clear, and when I look down to read the print blackens and comes up a bit. So far I've been able to wear them all waking hours and forget I have them on. I'll try this for a that too soon to see any difference without them?

gwgs 23 Mar 2015, 03:33

Stan, you'll also find these type of bifocals on eBay, many sellers are offering them with no prescription in the top, and a reading add in/segment below.

gwgs 23 Mar 2015, 03:33

Stan, you'll also find these type of bifocals on eBay, many sellers are offering them with no prescription in the top, and a reading add in/segment below.

Stan 19 Mar 2015, 07:20

Thank you CJ. You all told me to use the readers as much as possible, which is hard to do with no distance clarity, so I did find what you suggested at Walgreens. They are much easier, as the clear distance on top is good and automatic shift to the reading portion when I look down is great. They don't even have a line. I will try them all day today.

Cactus Jack 17 Mar 2015, 20:27


What you described about your eyes having to re-focus, when you take off your +2.00 glasses is one of the reasons people start thinking of bifocals. When you wear your glasses, your Ciliary Muscles and Cryatalline Lenses are pretty much relaxed while you focus close and have no ability to do anything about the blur. When you take off your glasses, your Ciliary Muscles and Crystalline Lenses have to suddenly go back to work to focus at any distance that is closer than about 20 feet or 6 meters. Bifocals help this situation.

Bifocals have two "segments". The upper one has your distance prescription, if any, and the lower part would have the +2.00. It is normal to look down to read and look up for distance so you automatically switch glasses powers as you need them.

The ideal thing would be to order some glasses made to your specifications.

However, that may not be necessary. If you look around, you may find some Over-the-Counter (OTC) bifocals with 0.00 prescription in the top part and somewhere around +2.00 in the reading part. They are not as common as single vision readers, but they are made and sold in the same places you would find OTC reading glasses for people in your situation with good distance vision, but in need of convenient reading help. It is hard to beat the convenience of having your reading prescription just a glance away. Also, you don't often loose glasses if you are wearing them.


Cactus Jack 17 Mar 2015, 17:03


In most countries, Opticians cannot do surgery. You have to find an Ophthalmologist who will do that kind of surgery, but it is not easy.

It is very unlikely that you will easily find one, for legal and ethical reasons, but it depends on the country. A very few members have been able to have surgery to increase myopia or hyperopia in Mexico or India.

One thing to remember is that in general, refractive surgery IS NOT REVERSIBLE. The only type that is reversible involves inserting an Internal Contact Lens (ICL) between the Cornea and the Iris or between the Iris and the Crystalline Lens.


george 17 Mar 2015, 13:48

If you asked an optician to give you lens implants to increase your myopia would they agree to do it?

stan 17 Mar 2015, 09:41

Thanks for the comments and advice. I am trying the less expensive way, and got a pair of +2.00's. They make everything close biggest and clearer, but I have to hold reading material a bit closer. I think I feel my eyes straining a bit. Everything a bit out is a total blur, so driving certainly isn't a possibility...I can't even make out the calendar on the wall. My eyes have to re-focus when I take them off. Let's see how this goes for a few days. I do like the look.

Cactus Jack 17 Mar 2015, 08:31


I agree, +2.00 would be faster.

I did not introduce the possibility that you have some Latent (hidden) Hyperopia because it is a little hard to explain until you have a better understanding of how the optics of the eye work. Many people who think they have "perfect" vision actually have Latent Hyperopia.

Hyperopia or Far or Long sightedness is the only refractive error that you can correct internally using your Ciliary Muscles and Crystalline Lenses. Often, before Presbyopia takes it away, you can correct Hyperopia without your even being aware that you are doing it. If you do that long enough, sometimes years, your Ciliary Muscles will get used to adding the extra PLUS you need and have difficulty relaxing. That is why people with recently diagnosed and corrected Hyperopia will often need a couple of prescription increases over a period of months after they start wearing glasses. Their Ciliary Muscles and Crystalline Lenses gradually relax. The same thing can happen IF you have Latent Hyperopia and wear PLUS glasses for reading and close work, the distance blur will gradually clear up. However, IF you DO NOT have Latent Hyperopia, it will NOT gradually clear up.

BTW, long term, mild, Latent Hyperopia is very hard to detect during an typical eye exam. Even a dilated or wet exam, where drops are used to paralyze the Ciliary Muscles, will not always reveal it. The drops don't always work long enough for the Ciliary Muscles to begin relaxing.

The problem with wearing single vision PLUS glasses, that are too strong, full time, is that they will give you the visual effect for distance as being Myopic. That could affect your ability to drive safely or recognize people who are not close to you. That is why I suggested bifocals. We can help you with a prescription with a little PLUS in the distance segment and stronger PLUS in the reading segment. Glasses like that would allow you to function pretty much as you are now and give your Ciliary Muscles an opportunity to relax and not work as hard. In fact, glasses like this have a name, Functional Bifocals.

If you have some Latent Hyperopia and your Ciliary Muscles begin to relax, you will need a prescription increase in a few weeks or months. Which is another reason to learn how to order from and online retailer like Zenni. If you stay with the same frame, you can change your prescription without comment after the initial comment period after you start wearing glasses.


svensont 16 Mar 2015, 16:33


I think the more power the better, with +2D it will happen faster.

You should start noticing difference after wearing +2 glasses for let's say 2h. Then try to read very tiny print without them.

You can also do a simple test, wear +2D glasses for some time and measure the distance from your eyes to a newspaper when the text becomes blurry. If you have some latent hyperopia then blurry distance will become clear after days, weeks or months.

Stan 16 Mar 2015, 16:24

Are you suggesting I start with +1.50 or +2.00? Is there any way to know how long "deconditioning" takes? I presume that proof that it is working will be more difficulty in reading without them. Should I start with 1.50 and work up to 2.00 or just jump in?

Cactus Jack 16 Mar 2015, 13:01


People who are Myopic essentially have built in reading glasses and their distance vision is blurry. If you REALLY have good distance vision, reading glasses WILL make distant things blurry while they make close things appear a bit larger and small text, such as on cell phone and tables, easier to read.

I am going to use some numbers and talk about how the laws of optics work, so bear with me.

Again, assuming you have perfect distance vision (0.00 refractive error) (distance in this case being defined as farther away than 20 feet or 6 meters), you cannot focus or see closer objects clearly unless you have more PLUS in your eye's lens system. The amount of extra PLUS you need is determined by how close the object or text is. The formula is:

Lens Power = 1 meter or 39.37 inches / distance to the object (units of measure have to be the same. For example, a common reading distance is 40 cm or 16 inches. If you do the math, you get the amount of extra PLUS you need.

100 cm / 40 cm = +2.50 diopters or 39.37 / 16 = +2.46 or +2.50

The formula can be re-arranged to yield focus distance:

100 cm / 2.50 = 40 cm or 39.37 / 2.50 = approx. 16 inches.

If you move the object closer you need more than +2.50 or farther away less than +2.50. The point is that the additional PLUS is required and it must come from somewhere.

When you are young and your Crystalline Lenses are very flexible, your Ciliary Muscles can add the extra PLUS without your even being aware it is happening. However, as you get older your Crystalline Lenses get stiff (Presbyopia) and ultimately, your Ciliary Muscles cannot squeeze your Crystalline Lenses enough to provide the extra PLUS. You then need an external lens to provide some or all of the required PLUS.

When you wear the +1.00 readers, you are relieving your Ciliary Muscles of some of their workload. All muscles operate on the "use it or loose it" principle. If you don't exercise your Ciliary Muscles they will get weaker and before long you will need more than +1.00 to focus clearly at close distances. However the amount of PLUS you need will never exceed the power required by the formulas above.

The solution to the blurry distance vision with the readers is to get bifocal or progressive glasses with the upper part at 0.00 prescription and the lower part or reading segment at +1.00 or whatever you need or want. If you want to get to where you NEED reading help, you will need more than +1.00 ASAP. The more PLUS you get and the more you wear them, the faster your Ciliary Muscles will become de-conditioned. If you get used to wearing +2.00 or more, you may begin having trouble with intermediate distances such as computer screens and then Trifocals can solve that problem.

You can order bifocals or no-line bifocals (progressives) from online retailers, pretty inexpensively, if you want to try them. Many of us are very pleased with Zenni Optical. We can tell you how to order from any online retailer.

Hey I'm 20 and am a -4.75. I'm hoping to get to -8 at the least. I've tried overreaction (wore a -6) for a few months but my myopia only increased slightly. Any advice on this?

Stan 16 Mar 2015, 12:09

Are you suggesting that if I use the readers even tho I don't need them now I can get used to them anyways? I am 35 and do sales. Will that have an effect on distance vision, which is a blur with these readers? How long does deconditioning usually take? Why do you say bifocals will be in order?

Cactus Jack 16 Mar 2015, 09:59


I forgot to mention that you CAN cause Presbyopia to progress faster than it does naturally. Presbyopia is caused by gradual stiffening of the protein in your Crystalline Lenses. Finally, they get so stiff that the Ciliary Muscles cannot squeeze them to increase their power for focusing close. Wearing + glasses to help you focus close will relieve some of the Ciliary Muscles work load and like all muscles, they will become de-conditioned, weaker and less able to focus. There are bifocals or progressives in your future.


Cactus Jack 16 Mar 2015, 09:47


Bad news, you can't induce Hyperopia. You eyes just won't let that happen.

Here is a link

That explains how the optics of the eye works. The two key elements are the relationship are the Total PLUS power of the eye's lens system and the distance from the back of the crystalline lens to the retina. This relationship has to obey the laws of optical physics as discovered by Sir Isaac Newton, of gravity fame, around 1700.

The eye's lens system actually has 4 PLUS lenses, but we typically ignore the humors. The distance from the crystalline lens to the retina is about 17 mm and the total PLUS optical power of the eye's lens system is about +58 diopters. If there is a mismatch between the distance and the PLUS optical power, either Myopia or Hyperopia result. The most common thing that happens is that the eyeball grows either too long (Myopia) or not long enough (Hyperopia). The dominant control of the growth process is genetic, but visual environment can also play a role. The important thing to remember that growth is primarily a one way process that typically slows and stops in the late teens or early 20s, generally there is no reversal of this growth process. For you to become Hyperopic, either your eyeballs would have to shrink in size (length) or the total PLUS power of your eye's lens system would have to become less.

Of the 4 lenses in the eye, 3 are either fixed PLUS power or in the case of the Aqueous and Vitreous Humor, semi-fixed, because blood chemistry can sometimes affect the Index of Refraction of the Humors. The only variable focus element is the Crystalline Lens. In its relaxed state, for distance, it has somewhere between +12 and +18 diopters. For focusing close, your Ciliary Muscles can squeeze your Crystalline Lenses to increase their + power, but you have no ability to REDUCE their PLUS power below their fully relaxed power..

The point is that Inducing Hyperopia is impossible, period. Inducing any Axial or True Myopia is very unlikely at your age, but there are two other possibilities if you want to wear glasses. You have already tried one of them. By wearing the -1.00 glasses you temporarily Induced some Pseudo or False Myopia by using your Ciliary Muscles and Crystalline Lenses, but Presbyopia is creeping up on you, as it does for almost everyone, and you no longer have enough Accommodation Range to compensate for the -1.00 glasses and be able to focus close. The other possibility is GOC. We can help you be a happy - glasses wearer and deal with all the issues. Let us know what you want to do.

May I ask your Occupation, Education, and where you live. All that information will help us help you.



Stan 16 Mar 2015, 07:20

I was always interested in wearing glasses but have been blessed with perfect vision. I got a pair of -1.00's and wore them for about 6 weeks. They were ok, but had trouble reading with them. Went for an eye exam, and was told my vision is ok... don't need glasses. Saw this site and conclude that becuase of my age I won't really be able to become nearsighted. Next best would be to get some + glasses, which is much easier. I am 35. If I wear + readers can I "induce" farsightedness? I tried a pair that make close bigger but blur distance. What is the possibility that I can get dependent on them and get a "real prescription"? How long would that take...would that work?

Soundmanpt 12 Mar 2015, 15:12


Having this work so well for this one test patient is one thing but as you know your going to have to do the same test on other willing patients to verify the same results in others.

You surely realize that as interesting what you have already done, if you could somehow reverse myopia then you could become a very rich man in a big hurry. As it is I am sure just like your test patient there are many others that soon may in contact with you wanting you to do for them what you did for this young lady.

So now that this young lady really is pretty much unable to see much of anything anymore without her glasses, how is she answering friends and family that must be very curious how her eyesight could have deteriorated so rapidly to need such strong glasses now?

Daland 12 Mar 2015, 14:42

Soundmanpt, it is correct, that she stays at about -8 at this time. This is, because I stopped progression.

When I first started the experiment, I asked her, how much should we try to induce. Her wish was somewhere at -5.

We reached this goal andthe progression stopped, as I told it her before. It stopped "automatically".

After that, we BOTH wanted to check, if there is more possible. So we went on, without a limit.

There have been 2 problems, why I stopped the progression at -8.

1.) It seemed too dangerous for me to go further, because the chance to get a myopia-coupled illness in the eyes will grow with the prescruption - I read this.

2.) It became to expansive - I agreed to pay the glasses, until we finish the experiment.

If we can return to a "normal" vision? I dont know, it is one of my "open questions".

This would mean, you could heal myopia and induce hyperopia.

At the moment I only know, you could induce myopia, maybe you can heal hyperopia...

My suggestion is, that the induction has something to do with the proliferation of cells in the eye.

Maybe the brain can control growth-hormons more as we believe at the moment...

Then shortening of the eye would mean, to reduce the cells of the eye...

So I can not say anything about this, because I never tested it.

But you all can be sure, that she really wanted the experiment.

I asked her sub-conscious, how she describes herself.

The answer contained strong glasses.

Greetings from Germany


Soundmanpt 11 Mar 2015, 16:39


So how is your test subject doing today? Your last report about her was that her vision had worsened to -8.00. Has her eyes now stopped changing? It would seem one problem with it is that is somewhat hard to control because you actually had tried to freeze her vision once it reached -5.00. Is this young lady okay now that she has her wish to wear glasses, but how does she feel that her vision is now so poor without her glasses? Of course when she first started becoming myopic being -.50 i'm sure she probably wanted her glasses to be somewhat stronger. If she isn't happy being so myopic will you be able to reduce her need for glasses if she requests it?

Daland 11 Mar 2015, 15:50

Today I want to give you a quick update on self hypnosis techniques:

I managed to come to a more deep state by using recordings I spoke before.

So I was able to go to a moderate state and set a more efficient suggestion for "pseudo" myopia.

On the whole my eyes needed 3.5h until they suddenly "jumped" back to the normal vision. Until then I was not able to relax the eyes - this was impossible for my eyes according to my suggestion.

The point is that we are surrounded by suggestions (e.g. ads and drugs), that might "reprogram" our brain.

I started the "pseudo-myopia-program" - if now anything stops this program and relaunches the "normal-vision-program", the pseudo myopia is immediately removed.

So I am working on a solution for a longer period.

Concerning real myopia induction:

Nothing changed till now. I keep my opinion: It is a real change in the eyeball.

Cactus Jack 10 Mar 2015, 08:21


I suspect that you may have some Hyperopia, but I am not sure. The +0.75 will help with focusing close, but I have trouble with the statement that your vision will be corrected in 6 months. It generally does not work that way.

Hyperopia is the only refractive error that you can correct without the external help of glasses or contact lenses. Many people have Hyperopia without realizing it. Instead, they think they have exceptional vision because low hyperopia has the same visual effect as a person who has Myopia and is slightly over corrected. If a person self corrects Hyperopia long enough they can develop what is called Latent (hidden) Hyperopia. Latent Hyperopia occurs when the Ciliary Muscles and Crystalline Lenses become so used to supplying the extra PLUS to correct Hyperopia that they have difficulty relaxing back to normal.

The problem with self correcting Hyperopia is that you can't do it forever. The lurking problem that almost everyone has is the gradual onset of Presbyopia. Presbyopia, which is the gradual stiffening of the gelatin dessert like protein that makes up your Crystalline Lens, actually starts in childhood, but it typically does not become a problem until the late 30s or early 40s. In early childhood most people have exceptional accommodation range. That is why you see young children reading or coloring, effortlessly, with the book very close to their eyes. As you get older, your accommodation range gets less and less until you can no longer comfortably focus close. If you have Hyperopia, some of your available accommodation range will be used up in correcting that, which leaves very little for close focusing. This causes the phenomenon of people with Hyperopia needing reading help a an earlier age than is typical.

The stiffening of the Crystalline Lenses slows down their reaction times and after focusing close for a long period, they may be very slow to relax. Wearing low power PLUS glasses will relieve your Ciliary Muscles and Crystalline Lenses of some of their workload. If you actually have some Hyperopia, the low power PLUS glasses will help reveal it, which is a good thing, but it is likely that you will discover that you need more correction than +0.75 in your glasses within the 6 month period. The ARC coating is nice, but I would not spend a lot for it.

I suggest that you review the threads that discuss Hyperopia and it many confusing symptoms. I also suggest that you consider a getting a dialed or "wet" eye exam. Depending on where you live, you may have to see a doctor other than an Optician. A dilated exam will help your Ciliary Muscles relax and begin to reveal any Hyperopia you may have. However, be prepared for a recovery period of several hours where you cannot focus close and will need protection from bright lights.

Also, the prescription is +0.75 (Spherical). All other colums (cylindrical, axis) are blank.

roityadav 09 Mar 2015, 11:13

During past few months I was excessively using smartphone and laptops. This I feel have taken a toll on my eyes. Now I can't t look beyond 2hours on my phone screen nor I can study as I feel strain on my eyes.

I consulted an optician for the same and he told me to use +0.75 lens (ARC) and said my vision will be corrected in 6months time. Should I trust him? I am able to read clearly without lenses.

Thank you for the information. I have been to Italy on business trips. Many years ago (1970s) to Naples and about 5 years ago to Rome. Unfortunately, I did not learn much Italian because almost everyone I worked with wanted to speak English. I enjoyed my visits very much.

I am very curious about your distance vision with your Mother's glasses. Are signs and other distant things readable with your Mother's glasses in bright daylight and at night?

If you wear your Mother's glasses and read a book, is the text sharper and clearer with your Mother's glasses?

Hold the book at a distance of about 20 cm from your eyes and slowly move it away from you. Notice where the text begins to get a little fuzzy around the edges. Measure the distance from your eyes to the book. Try to do this 3 times and average the distance. Let me know the results. It is best to do this test in the morning when you are rested and have not been reading.


John 05 Mar 2015, 23:52

Thanks for your replay CJ,

Well Im 25 live in Italy, student of economics. No miopia, but always want to wear glasses. My bro precrip is minus 1,5 and mom, + 2,5.

One year on this boring mission of try to go to glasses. Unfortanetely no sucess because my vision is still Almost perfect, but for my surprise during in driving in the nighlight público tend to appear as a star now, and after wear my mothers glasses for astigmatism, long distamce Get better. Is this astigmatism have any relation with the process of force ciliary muscles? Or maybe I always have some astigmatism but didnt percept...?


Cactus Jack 05 Mar 2015, 19:40


It would be very helpful if you could tell me a little more about yourself, your brother's complete prescription and your mother's complete prescription.

The information about yourself that would be most helpful is your age and occupation.

May I also ask where you live?


John 05 Mar 2015, 15:12

Dear CJ,

It is possíble to develop any other aberration, but not myopia, while trying induce myopia with minus cls? Im trying hard for 1 year now, but no diference using mmy brother myopia glass,Im still 0.00. Big after try mother glass astigmatism, my vision increase much betterr. Is there any explanatione?


Cactus Jack 05 Mar 2015, 13:23


A person cannot have both Axial or True Myopia and Hyperopia at the same time. Both are caused by a mismatch between the total PLUS power of the eye's lens system and the size or length of the eyeball. In the case of Axial or True Myopia, the eyeball is too long and in the case of Hyperopia, the eyeball is too short.

A person can have both Axial or True Myopia and Presbyopia at the same time because they have two unrelated causes. I explained Axial or True Myopia above. Presbyopia is caused by the gradual stiffening of the Crystalline Lens or weakness of the Ciliary Muscles or both. It is not unusual for an older person with Myopia to also need Bifocals or Trifocals to focus close if they cannot use their Ciliary Muscles and Crystalline Lenses to add the necessary PLUS for the purpose.

A few very fortunate people, with Myopia in the -2.00 to -3.00 range and NO Astigmatism, can just remove their glasses and they are automatically focusing at 50 to 33 cm.


Alexander  05 Mar 2015, 05:58

Cactus Jack,

Hm... but I didn't say I want a hyperopia.

Well, could you answer in one more question: is it really that person having a myopia in old age have a hyperopia also? Or it's a myth?

Cactus Jack 04 Mar 2015, 10:02


Because of the way the optics of the eye work, you cannot Induce Hyperopia. You can CORRECT mild Hyperopia, internally, using your Ciliary Muscles and Crystalline lenses, but eventually, Presbyopia catches up with you and you loose that ability.

You might find this link educational.


Alexander 04 Mar 2015, 05:51

Oho. Somebody wants induce a myopia... wow. Are there people who want a hyperopia :-D Don't try: only 40+

John 04 Mar 2015, 00:05

Daland,thanks Very mich for the explanation

Are you trying to induce myopia in yourself? By self hypnosis or with the help of somebody else

 02 Mar 2015, 15:02

can anyone draw a visual about how they think this looks and works? I'm dying to try it.

Daland 02 Mar 2015, 14:14

I wrote a shote description of the first steps of self hypnosis which are completely harmless.

If you are possible to become totally relaxed in less than 5 minutes, its time for the next step.

Daland 02 Mar 2015, 14:12

A short explaination of self hypnosis:

1. lie down, hands beside the body, so that neither feet or legs nor hand touch each other.

2. close the eyes and think "sleep" - do not repeat it often, no, just think of it as a FACT.

3. Now imagine your feet and lower legs become very very heavy and sink down in the bed/couch.

it is possible not to think that your body parts become heavy. you can think that the body relaxes and that there are weights bonded to the body parts pulling them down.

4. repeat these thoughs until this happens to your feet. Then go on by relaxing your upper legs, hands, lower arms, upper arms, body and back, face, eyes and at last your neck.

5. now your are completely relaxed and feel very heavy.

6. now imagine, with every breath, you breathe out stress and tension and inhale relaxation. you will feel something like waves of deeper and deeper relaxation.

It is also possilbe to use the heartbeat (with very heartbeat) or music or every car driving in front of the house - there are no limits.

7. if you have enough think, that you can reach this relaxation more and more easy from now and ! if YOU want to relax AND LIE DOWN and you think the word "sleep", you will immediately go back to this state.

8. think that you will return to the awake state and pulse and blood pressure are optimal. OR just turn around and sleep normal.

9. repeat this as often as possible and notice that reaching relaxation is more and more easy.

John 02 Mar 2015, 11:43

Daland Nice explanation. I AM Very interested in the techinique of self hypnoteisis. Probably I would never found Antyone to this Around here

Daland 02 Mar 2015, 10:26

Another point to self hypnosis:

At the moment I am trying to increase the time, the pseudo myopia is "active" - if someone is interested to try this, write it here and I will write a short descripting of the technique.

The first thing is to learn self hypnosis -that after some weeks of training you can start with suggestions.

Daland 02 Mar 2015, 10:23

Thank you all for your responses!

The first thing is "Self Hypnosis" - this is a good thing to calm down and sleep very easy at night. If I use this, it takes less than 5 min to sleep.

The problem is, that the "normal" conscious controls our thoughts and forms the suggestions for the subconscious.

So this needs to be very active all the time and can't "relax" to let the subcon. "rule" everything.

The result is the lower level of hypnosis (Called in Germany "Somnolenz").

In this level, it is not possible to set any suggestions that should stay for longer, be active, when eyes are open and are not "good" for the body.

If you are good at hypnosis and know all the suggestions, you brain doesn't need to work that much and seldom you reach the second state (German: "Hypotaxie"). There I was able to get the pseudo myopia myself. But this was only 10-15min then my brain realized, that it's better to relax the ciliary muscle.

If you want to set a suggestion, that lasts as long as something changes it, you need the deepest state (German: "Somnambulismus"). To reach this, there needs to be a second person telling the suggestions.

What happened to the eyes of my proband?

I can't say, if the eyes really growed... My suggestion was, that the eyeball should grow till I stop it or it reaches (first) -3 and later some higher.

The brain takes EVERY suggestion word by word! If I say, someone touches a hot oven, there will be the reaction of the skin some minutes later (Blister).

The ophtalmologist said, he NEVER saw this before.

About me:

I am a show hypnotist and got all possible certificates for this classical hypnosis.

Cactus jack 01 Mar 2015, 19:38

John and others,

Inducing Axial or True Myopia where the eyeball physically grows longer in a few days or weeks using Hypnosis seems very unlikely to me. However, considering how Pseudo or False Myopia is caused and works, Inducing Myopia using Hypnosis might be possible, but it depends on what is possible with Hypnosis. From a results point of view, it does not matter what kind of Myopia it is, the symptoms and corrections are the same, minus lenses. The only difference between the two types of Myopia is the relative permanence and reversibility.

Axial or True Myopia usually involves the physical growth of the eyeball or the rare increase in lens power. Even in the worst cases of extreme progressive Myopia, the rate of increase of even 2 or 3 diopters per year is rare. Axial Myopia, as a result of eyeball growth, involves only about 0.3 mm per diopter of extra length and that does not happen very fast.

A possibility is back to my old favorite, Pseudo Myopia. That involves only the ciliary muscles and crystalline lenses and it can happen very quickly if you are young and your ciliary muscles are in good condition. Any time you focus very close, your ciliary muscles can increase the PLUS power of your crystalline lenses by 3 or 4 diopters in a fraction of a second and I know of people who have trained their ciliary muscles to add +10 or +12, but that takes some time for the muscles to get that strong and very flexible crystalline lenses.

I have always been curious about hypnosis, but don’t know much about it. It seems like I have heard of a theatrical hypnosis trick where the subject is told to raise their arm to a certain position and keep it there until the hypnotist tells them that they can lower it. If that is true, it may be possible, under hypnosis, for the hypnotist to instruct the subject to focus on something close and maintain that focus until released. If that occurred, the ciliary muscles would squeeze the crystalline lens and increase their plus power. If the ciliary muscles would maintain that condition, the subject would have a substantial increase in apparent myopia. I don’t believe that the source of the myopia could be identified without using an Ultra Sound device to measure the actual length of the eyeball, such as they use to determine the power of an IOL prior to cataract surgery.

The power of hypnotic suggestion is very great and there is such a thing as self hypnosis. Could that be a factor in Inducing Myopia? I don’t know, but would be very interested to learn if any of our members who want to be more myopic have considered trying it. If so, perhaps Daland’s Hypnotist would be willing to share the technique.


John 01 Mar 2015, 11:45

Holy Crap this ia f..... Amazing, sorry my Words. Probably no Body did this before. CJ what si tour opiniões about Daland experiment?

Likelenses 28 Feb 2015, 19:11


Are you a licensed hypnotist,or is it just a hobby of yours?

John 28 Feb 2015, 15:38

Do you intend to be induced into a hypnosis to Get myopia Daland?

Daland 28 Feb 2015, 14:06

(Part 1/2)

This is not "bull shit"!

This is the correct, but short description of what I observed and did.

It is the common opinion, that you can't do anything against the will of the hypnotized person, but this is absolutely wrong. Maybe it fits to some "indirect" techniques like ERICKSON, but not the real hypnosis.

The only thing is to give the brain a hallucination.


If there stands a person in front of my proband and my proband gets a water pistol in his hand, I just need to tell him, that when he opens his eyes, the person in front of him will be a hungry lion who is much faster than he. So his only possibility to survive is to shoot the lion. What will he do? Shoot.

Hypnosis is a mighty tool. My idea was to go apart from processes in the brain to macroscopic reactions at the body. And? Until now it seems to work!

You always need to be aware of things written in a book.

I once read a book of a Prof. Dr. who should know well about the things he writes...

He wrote: The brain cant understand the word "NO" or generally the negation.

Proof: (You can try this on your own!)

!! Now do not think of a purple elephant! !!

And? Now vou have this elephant in your brain, right?

It's proven that the brain cant understand negation.

Daland 28 Feb 2015, 14:00

(Part 2/2)


This information went to your conscious, but hypnosis uses the subconscious.

Most of the common known things about hypnosis are wrong and often copied from others - and no one thought about that, what he copies. It's like "Control C + Control V" without reading the text before.

So what I want to say is, that you can't say just "NO" it will not work.

This is why I did the experiment an seem to be successful.

Soundmanpt 28 Feb 2015, 10:04

I have always heard that it is impossible to have anyone do anything that is harmful to others or themselves while under hypnosis. Causing ones eyesight to be changed would be considered by most doctors as harmful because you would have impaired their vision.

 28 Feb 2015, 09:31

Bull shit

 28 Feb 2015, 09:31

Bull shit

John 28 Feb 2015, 01:09

OMG Danland are you serious ? !

Daland 27 Feb 2015, 16:34

Some month ago I asked about any knowledge about the influence of hypnosis to develop any kind of vision impairment.

Now it is time to write the first conclusion:

I had one friend who had the same wish as most people here in this forum: to be myopic oder hyperopic.

She agreed to try hypnosis. I gave the order that the eyes should lenghten and become myopic till -6 and stop then.

This was repeated on 2 following days.

At first nothing changed, but after 9 days the eye started to "grow".

One week later the optometrist had to prescribe -0.5.

Then it went very fast - during only 4 weeks she reached the -5 mark.

The optometrist did not believe, what he saw. Such a progression, he said, he had never seen before.

Then I did the hypnosis again to stop the development.

I had the question, if I really induced this process by only using words.

So using something like "atropin" the Dr. checked the eyes and came to the conclusion that this is real myopia!!!

It is no change of pressure in the eye or any change in the lens. The eye has grown again. This is fantastic, because she ist 25 and under normal conditions nothing will grow any more.

Today she got to -8 and we stopped the delvelopment because no one knows about any risks. - Maybe nobody did this before.

There are some more questions for me:

- Is it possible to do the reverse thing, to develop hyperopia by shorten the eyeball?

- Is it possible to cure myopia?

- Is it possible to cure or induce astigmatism?

- Is it possible to induce presbyopia by "deactivating" the ciliary muscle?

The technique behind this is NOT the "modern medical" hypnosis as ERICSON invented.

It is the old technique reactivated for hypnosis shows.

Maybe someone tried the same thing or used other techniques...?

John 27 Feb 2015, 12:14

Or maybe I develop any other aberration?..

John 27 Feb 2015, 10:45

Thanks Cactus! Wow that strange so.. I really haver no idea how my vision is not perfect. The explain for Star effect in the public light is there anyone? It is normal? And It os normal to see better using + glasses?

Sorry my english

Cactus Jack 27 Feb 2015, 07:10


The general answer to your question is No.


Cactus Jack 27 Feb 2015, 07:08


Myopia and Astigmatism are unrelated and have different causes. Astigmatism is typically caused by uneven curvature of the front surface of the cornea. It may be caused by uneven stress on the cornea, but if that is so, the cause of the stress is unknown.

You might be able to induce some temporary Astigmatism using rigid contact lenses if you could keep specially designed rigid contact lenses with cylinder. Rigid contact lenses can temporarily reduce Astigmatism by reshaping the front surface of the cornea. This phenomenon is known as spectacle blur. It occurs when a person, who has some astigmatism, wears sphere only contact lenses and then removes them at the end of the day and puts on their glasses with cylinder correction. The spectacle blur goes away in an hour or so as the cornea resumes it natural astigmatic shape that matches the cylinder and axis correction in the glasses.

Specially designed contact lenses, used only while sleeping, can temporarily reshape the cornea to correct some myopia and astigmatism, but it is not considered a permanent solution for either one. Temporary in this case is a relative term depending on the individual.

If anyone knows of successful correction using this method, I would appreciate hearing about it, along with the original prescription and the length of time that the reshaping remained effective.

It is possível to índice a astigmatism using minus cls?

John 26 Feb 2015, 14:44

Hi foks, tryning to índice myopia with strong minus cls for 1 year righ now. Im in -6,5 full time, and reading a LOT everyday. Probably no suecas in índice myopia, because Im trying my brother minus - 1,,75 glass and no much diference. But for curiosity I take my mons plus + 2,5 right now in the living room and WHOW my vision becomes really bettger even in the day light! In the night while driging the public light tend to appear ditorced as a star. I start to trink if I could be developed some astigmatism...or something else, But no what I really wanted, that si myopia. Ia this possible?! Im 25; tryning to índuce myopia since 24, thanks

til 26 Feb 2015, 13:53

Hello Cactus Jack

Thank you for your reply. I'm 27. My most recent eye exam showed -0.25 no cyl. for both eyes. That was 6 weeks ago and done by an optometrist. I have been told before though that I require +0.25 as well and an autorefractor once even diagnosed a small amount of astigmatism. So far I haven't experienced any visual problems at all apart from self inflicted ones.

Cactus Jack 25 Feb 2015, 22:37


People who have high myopia and those who do high prescription GOC seem to be able to switch between glasses and contacts with no difficulty after they have grown accustomed to the different image sizes. I experienced something similar with GOC, switching from a low regular prescription glasses to GOC in the -14 range. There was an initial adjustment to the GOC combination that took a few days of intermittent wear, but after that it was not much of a problem to switch between my regular glasses and GOC. The brain is extremely malleable and once it had figured out the correct "program" for dealing with the minified GOC images it was like my brain just loaded the appropriate program to turn the minified images delivered by my eyes into acceptable vision. Then, when I took out the contacts and put on my regular glasses, my brain just loaded the program for that input.

Wearing significant over correction involves programming the focus control system and conditioning/strengthening the ciliary muscles, which should take a bit longer than just getting used to changes in image sizes and apparent spatial relationships.

Hopefully, your crystalline lenses are still flexible enough to accommodate the additional PLUS for distance vision AND the Additional PLUS you need to focus close.

May I ask your age and your current prescription? You have probably posted that before, but I just don't try to remember everyone's age and prescription.


til 25 Feb 2015, 15:33

I meant to write on and off wear.

til 25 Feb 2015, 15:32

Hi, I just got some -6 glasses today which I've been wearing this afternoon. I don't require any correction. The prescription is bearable, only things closer than 40cm are challenging.

Going through older posts on eyescene I read that the brain can adapt to the minification caused by vertex distance if you wear minus correction constantly. The thing is I don't, at least not the -6 ones. Does anyone know if that adaption is still possible with this kind of and off wear? I wouldn't expect it to happen soon anyway I was just wondering what the chances may be. Maybe people who use both glasses and contacts can share some experience.

Cactus Jack 23 Feb 2015, 23:19


Unfortunately, no. Every few years, someone markets vision correction programs, that involve exercises to improve vision. The Bates Method and The See Clearly Method are two examples. In general they don't work.

There are legitimate vision training programs offered by Eye Care Professionals that can help with some vision problems. For example, using a patch on the good eye to strengthen vision in an eye that is being ignored by the brain can help very young children with Amblyopia, but it must be done usually before the age of 6 or 7. Eye Positioning Exercise Therapy can sometimes help with certain types of Strabismus where the eyes are misaligned. Unfortunately, Astigmatism and Myopia can only be corrected with external lenses, glasses or contacts. If a person is old enough for their vision to have stabilized, usually around the early 20s, Refractive Surgery, such as Lasik, is an option.


Alexander 23 Feb 2015, 02:19

Cactus Jack,

Thank you for the useful information. It's really interesting.

Well, can I restore my eyesight with the long time exercises?

Cactus Jack 22 Feb 2015, 17:12


One of the symptoms of uncorrected Astigmatism is seeing two images with the eye that needs correction. This occurs because that eye actually has two focus distances.


Cactus Jack 22 Feb 2015, 17:10


Thank you for the information about your favorite subjects. Many of the questions involving optics and vision require the use of mathematics to answer. Fortunately, the math involved is only slightly more complex than basic multiplication, division, and a tiny bit of algebra. The fundamentals of optics were discovered and formulated by Sir Isaac Newton around 1700. The fundamental formula defines the relationship between focal distance and lens power. It is

Focal Distance = 1 meter (100 cm or 1000 mm) / Lens Power.

an example would be that a +2.00 lens focuses at:

100 cm/2.00 = 50 cm.

Minus lenses are a bit harder to understand because their focus is actually imaginary, but we can still work with it. The key is understanding that glasses cancel out or neutralize actual refractive error. That means that a -0.75 in glasses or contact lenses cancels out a refractive error of +0.75 in your left eye. Without correction, you are actually "wearing" built in +0.75 lenses and the Focus Distance is 100 cm / 0.75 = 133 cm (1.33 meters). That means that everything beyond that distance is increasingly blurry.

Sphere refractive error is usually caused by a mismatch between the optical power of your eye's lens system and the length of your eye ball. The distance between the back of the eye's lens system and the retina is about 17 mm. That means that the total power of the eye's lens system is about +59 diopters spread over 4 lenses. and the excess length is about 0.3 mm per diopter or about 0.4 mm in your left eye.

Astigmatism is different. It is usually caused by uneven curvature of the front surface of the cornea. By convention, the axis is the long axis of the cylinder. 0 degrees is horizontal and the numbers increase in a counter clockwise direction, looking at the patient, through 90 degrees (vertical) to 179 degrees. In your case, the long axis of the cylinder is 170 degrees and the steepest curve direction is 90 degrees from that or 80 degrees. The cornea is a very strong PLUS lens and the slightly steeper curve results in a little more PLUS in the 80 degree direction and no change in the PLUS power in the 170 degree direction. The correction is a cylinder lens that has a long axis of 170 degrees and -0.75 in the 80 degree axis.

You probably should be wearing glasses full time with the latest recipe (prescription). If you decide to have some glasses made, you should wear them full time for 2 weeks and then make the decision about how much you want to wear them. That will give your brain time to become accustomed to working with the image from your Right eye and having a quality image from your Left eye.

If you are interested in how your eyes work, I can provide a link to a very good explanation.


Alexander 22 Feb 2015, 14:15


Cactus Jack,

Interesting information. One more question: I guess I have an astigmatic symtom of myopic eye. Because of bright objects, for example, lamps, are doubling.

But the device I wrote didn't show about.

Could it be an astigmatism untill -0.5 or illusion?

Alexander 22 Feb 2015, 13:25

Cactus Jack,

There is a fashion of wearing glasses in Russia. All of my classmates tried to wear them. But it doesn't occur so long: appearing of an "eyeache." So, I wear often, but not always. And I don't read and write with them.

The second question is difficult. I've thought and decided I like Russian, English and "Social science" ("obscestvoznanie").

Cactus Jack 22 Feb 2015, 12:58


You do not need to apologize for your English. It is very good with very few mistakes. English is not an easy language to learn. English has many what are called irregular verbs that do not follow rules for usage.

You probably need to do a lot of reading. Low and balanced myopia requiring minus sphere correction is a bit like having built in reading glasses, Astigmatism causes blurry vision at all distances and must be corrected externally by glasses, contact lenses, or surgery. Usually, if you have significant uncorrected astigmatism in one eye, the brain will not use the image from that eye very much, but will depend on the vision from the better eye.

Do you typically wear glasses or contact lenses?

May I also as about your favorite subjects in school?


 22 Feb 2015, 09:24

Cactus Jack,

Good evening. I don't use a translator. In other case the translation would be more awful, especially "Gogle Translator". Sorry for my mistakes: I have a little knowledge of this language.

I've 15 and I'm studying at school.

Well, thank you for the answer.

Cactus Jack 22 Feb 2015, 08:41


It is possible that your prescription of

OD Sph -0.50

OS Sph -0.50

was a compromise prescription, similar to what is occasionally prescribed for contact lenses to avoid the use of toxic contacts. The method is 1/2 of the Cylinder and add it to the Sphere.

It is certainly possible that your present for your Right (OD) eye is 0.00 or Plano (PL) and Cylinder -0.75 Axis 170 and your Left (OS) eye is Sphere -0.75 without any Cylinder. Your eyes do not necessarily track together and sometimes have very different prescriptions.

Two things to remember about vision.

1. Vision actually occurs in the brain, the eyes are merely biological cameras.

2. Your brain processes the two images and will always choose the best image as the primary data source and use the image from the other eye for supplementary data, if it is usable.

If you wear glasses that fully correct your refractive errors, you brain does not have to work as hard to provide you with what you perceive as good vision.

Glasses lenses with Sphere PL and Cylinder -0.75 Axis 170 are easily made. Toric Contact lenses with Sphere 0.00 and Cylinder -0.75 Axis 170 are expensive and difficult to fit satisfactorily. The problem is that Contact Lenses move around and often rotate some as you blink. If a Toric Contact Lens rotates out of correct Cylinder orientation, your vision in that eye is worse than it would be without contacts at all. You vision may alternate between very good and terrible as you blink. That won't happen with glasses.

By the way, this discussion would be better on the Vision thread unless your ultimate goal is to increase your myopia. Also, may I complement you on your English. Are you using a translation program or have you studied English. May I also ask your age?


Alexander 22 Feb 2015, 06:20

Cactus Jack,

I guess you didn't understand me. I was visiting a doctor before New Year and she examined with a special device. Doctor didn't declare the results but at first gave a recipe (at this moment she said I've an astigmatism an even tried the second glasses):

OD sph. conc. -0.5

OS sph. conc. -0.75

Dpp 64

And after when I began detect an astigmatism:

OD CYL -0.75 ax 170°

OS sph -0.75

Dpp 64

Comparing the recipes, I have an opinion that the right eye has a myopia too because the last recipe has a myopic lense.

So, I recently examined my eyesight with the special device, not situating at the clinic. Its results wrote by a person.

OD SPH PL cyl -0.75 ax 170°...

I didn't try spherocylindrical lense but I'd like to point out that I see through Cylindrical lense perfectly. It means I have no eyesight sphere -0.75 with the right eye. And I memorise myself I had last just sph -0.5. The during recipe hasn't sphere mean. It's strange...)

Don't be concerned. There have been worse corruptions of my ES name. The Cactus is from a friendly nickname I got when I was young. I fell or was caused to fall off a Shetland Pony that had a mean streak and into a Prickly Pear Cactus. Fortunately, no permanent damage other than my pride. I was about 11 years old and thought I was smarter than the pony. I was mistaken.

I am still a bit confused about the numbers you have provided. Could you provide your complete precription as provided by the Examiner? Also, the time interval from when you got the -0.50 prescription until the -0.75. Astigmatism can change, but it typically happens very slowly. Most cylinder and axis changes are the result of patient inexperience rather than actual changes. Determining the Axis Angle is the most subjective part of an eye exam. I have developed a technique for making sure the Axis is as accurate as possible, but it only works if you actually need cylinder correction for astigmatism.

It is also interesting that the Cylinder was listed without specifying an Axis. Cylinder without Axis is meaningless.


Cactus Jack 21 Feb 2015, 10:40


Usually, if there is no Sphere, it is listed as either 0.00 or NA (Not Applicable). An increase in Sphere from -0.50 to -0.75 would not be unusual.

It is possible that the examiner just made a mistake and entered the prescription in the wrong block. I suggest you verify the prescription with the examiner. If the examiner suspects that you plan to order glasses form a different retailer, they may have purposefully entered the wrong values. It is not ethical, but it happens.

You might consider another exam by a different ECP.

Good morning.

I have a problem with a recipe.

OD cyl -0.75

OS sph -0.75

The question about OD eyesight. Why hasn't OD a sphere? My last recipe of that eye was "OD sph -0.5". I am seeing through that glass well, but I don't know what myopic diopter has the eye.

Sorry for my English.

LXW 19 Feb 2015, 13:35


thanks for your posting. I have tried some adresses in germany, italy, france and austria. But the problem in europe is the doctors are not allowed to do it because of codex and so on. My wish is to get ICL with a plus power of about 10 or so.

Perhaps there is a clinic in Serbia, but i have to write to it. They do it for 1.000 EUR per eye, but only to people who have bad eyes, not good eyes :-(

hi bracesfan,my rx is -3.25/-3.50,have you any 15 base out for sale

bracesfan 19 Feb 2015, 01:40


The prism corrections I mentioned are for each eye individually, of course.

I think you hit the nail at the and of your contribution.

If some latent strabism is present it can be the starter for pushing the corrections up. If there is none you tend not to influence your muscles more and need objectively more prisms.

I know that in some cases when patient get used to prism correction during the examination the prism correction isn´t recommended and visual training is preferred.

I wouldn´t play games with vertical prisms - they are much more risky and dangerous for common life. But from my prism bar examination I guess I´ve got some 2 pD of vertical difference.

bracesfan 19 Feb 2015, 01:23

All, Ian, LEO:

I wouldn´t be afraid of wearing prisms that much.

I have been wearing them for some 5 years nonstop and maybe 15 years before it with some delays. No harm, no pushing to higher diopters.

The only reason for going up is not real need of it but the desire for higher prescriptions and strange looking glasses. I have never had real need of prisms like strabism or diplopia.

When I was beginning with it I just changed my myopia prescriptions incorporating prisms into it. Recently, with higher prisms, I just ask my friend optician to order them for me.

Remember, the best way is to find some friendly optician and be absolutely honest - just say that you like it and desire to wear such glasses. After all, it´s only about money.

Though I have some old idle prism glasses with weaker prisms I´m not sure you would favour them. And, of course, you must not forget the spherical prescription which is about -3 diopters in my case.

BTW, I´m 52 ...

ian, hi! Where do you live?

Cactus Jack 18 Feb 2015, 08:44


Are the prism values you listed total prism (both eyes added together) or for each eye individually?

I am not convinced that prism "addiction" is as common as generally believed, but it is more than a rumor. I think what happens is similar to latent hyperopia correction and sometimes myopia\ with this scenario: The examiner is reluctant to prescribe full correction of strabismus or refractive error because of tolerance issues. In the case of Esophoria (requiring BO prism) or Exophoria (requiring BI prism) there is actually more need there than is either exhibited or prescribed in the initial examination.

In the cases of Strabismus or Latent Hyperopia, after wearing the prescription for a few months, the muscles involved have relaxed some and another exam reveals the need for additional prism or additional PLUS in the prescription. In both instances, muscles are involved and while changes are expected in Latent Hyperopia as the ciliary muscles relax, changes in muscle state in the eye positioning muscles as those muscles are permitted to relax (or become accustomed to a particular state) is looked upon as "addiction" when it really is not.

BO is easier to tolerate because it has the same convergence effect as focusing close or reading. BI is harder to tolerate because there is never a requirement for the eyes to diverge beyond both eyes pointing straight ahead for distance. The eye position control system in your brain is programmed to allow your eyes to track together in all directions and converge for focusing close, but it has to be retrained to allow INTENTIONAL divergence. The eye positioning system works like an Open Loop Servo system where the control system does not know the actual position of the muscles (there is no feed back system). Instead, it moves the muscle pairs to match and fuse the two images. If, for any reason, the control system cannot match the two images, double vision occurs. The general term used is muscle imbalance, but the problem could be in the muscles, the nerves controlling them or the control system in your brain. If you don't have any "Latent Strabismus" you may be able to wear prism without any apparent consequence, but if you have some, wearing prism may reveal it.

Remember, my background is engineering and my analysis is based on control system design rather than medical understanding. If a person has double vision problems, the only solutions available are Optics, Vision Training, or Muscle Surgery even if the problem is in the nerves or in the brain.

I want to wear glasses with a prism. But i don't need it.

You wearing glasses with a prism right now?

bracesfan 18 Feb 2015, 00:21


I have been wearing prisms for more than 5 years. Of course I don´t need them, I just like to wear strange glasses and the way how prisms divert eyes. I got to 15 pD base in and 20 pd base out. Both are tolerable but comfortable only up to 10 BI and 15 BO.

So far I haven´t noticed any addiction or pushing up to higher corrections. Nor did I observe any distortion. Diplopia is present only when I maximally release my sight and a few moments after taking the glasses off.

The same feels my friend who wear similar prism correction.

I guess the prism thing is strongly individual and the claim about prism addiction is largely only rumour.

Cactus Jack 17 Feb 2015, 08:51


Yes. One of the main reasons ECPs are very reluctant to prescribe "first" prisms is that it is very easy to adapt to prism correction, particularly Base Out prism, because it causes your eyes to converge as if you were focusing close. Convergence is necessary for you to NOT see double when you look at something close, so it is a natural function.

Once you become accustomed to wearing prism correction, you may have difficulty fusing images without your glasses with prism.

Unlike Inducing Myopia, which is age dependent, you can adapt to prism at any age because it involves the eye positioning muscles and the position control system in your brain.

There is a big downside to needing significant prism in your glasses, making glasses with significant prism is almost a lost art as is fitting glasses with prism. Incorrectly made and fitted glasses with prism introduce distortion and often cause reduced visual acuity and remakes of the glasses.

Hello Excuse,

same at my side!

But unfortunately there is no doctor in europe who will cut my eyes for beeing an high myopic or put in ICLs (high plus) to be myopic for term.

But i don´t give up and save money for the time...


Excuse 08 Feb 2015, 10:09

Thanks everyone for the advice! I just re read my post and I can't get over the typos, sorry about that!

I used to be ashamed of wanting to wear glasses so badly but now I don't care. It's funny to think that people cut their eyes open to not have to wear glasses anymore whereas I desperately want them on me all the time. I can't help that my brain has got wired this way so I might as well embrace it.

Soundmanpt 07 Feb 2015, 10:05


The advice you have gotten from both "specs4ever" and "Cactus Jack" is totally right. Like specs4ever said about the glasses your planning on ordering. You don't want to have that much difference between your right and left lenses. Only keep the same -.50 difference. So more like -1.50 / -2.00 or 2.00 / -2.50 as well as your real astigmatism numbers (CYL and axis) I don't think it is a wise idea going too strong just in case your eyes can't tolerate the strength of your glasses then you will have a problem. Like Cactus Jack said going even weaker than I said to start with wouldn't be a bad idea, -1.00 / -1.50 or -1.25 / -1.75, might be better to start with. Also like Cactus Jack said very few people pay any attention to your lenses only the frame. Also most optometrist will actually recommend full time wear for someone with a rather weak astigmatism correction even so you could be wearing your current glasses and all you need to say if for any reason anyone would ask is that you have astigmatisms and need to wear your glasses to prevent headaches.

Cactus Jack 07 Feb 2015, 09:00


You really do not need to explain to anyone why you wear any kind of vision correction and you seriously need to get over that. No one, even an Eye Care Professional (ECP) knows what you actually see, with or without glasses or contact lenses. Frankly, it is no ones business why you wear glasses. Just make up your mind to do it, the questions (if any) will only last for a day or so and that will be the end of it.

Lets talk for a moment about what a prescription of -0.50 and -1.00 mean for your vision. Vision occurs in the brain and the eyes are merely biological cameras. IF there is a difference in image quality, your brain will ALWAYS select the best image for the situation and use that image as the basis for what you see. The -0.50 means that everything beyond 2 meters or about 6.5 feet is increasingly blurry and the -1.00 with astigmatism means that everything is a bit blurry, but it is more blurry beyond 1 meter or a bit over 3 feet. If it were not for the astigmatism, I would say that your brain uses the -0.50 eye for distance and the -1.00 eye for close, but it really does not mater. Your brain is perfectly capable of correcting what you see, IF it knows what something is supposed to look like. In fact, your brain can create images with out any input from your eyes - ever had a dream? - but correcting blurry images takes a lot of extra work.

At your age, there is nothing wrong with wearing glasses that are a bit stronger than you actually need If you like the extra sharp vision they provide. The only rule is that you increase the Sphere part of your prescription by the same amount in each eye and that you copy the cylinder and axis EXACTLY as it was in your original prescription. The other trick is, if you want to increase your prescription without others noticing, keep the same frame style in the new glasses. Very few people notice moderate lens power changes, but almost everyone notices if you change frame styles.

If you would feel better with an excuse, just say that you were having some vision problems and your eye doc said that you should wear your glasses full time for the most comfort. No one is going to ask you prove it or if they do, THEY are the one who needs help.

Please let us know how you get on with your glasses and please feel free to ask more questions if you want to. Welcome to the group.


specs4ever 07 Feb 2015, 08:37

For the best results Excuse I would suggest adding the same amount of over correction to each eye rather than doubling the original prescription. If you are -0.50 and -1.00D now, then you could go to -2.50 and -3.00D Also it is best if you use the correct amount of astigmatism from your last prescription.

You could likely wear your old glasses in to work for a few days and if anyone notices or says anything you can tell them that you ahve had glasses ever since you were 17 but you never wore them and now all of a sudden your eyes seem to ahve gotten worse and you are getting new glasses.

Cactus Jack 07 Feb 2015, 08:29


If possible, stay with the higher power CLs. In a pinch, you can wear low power Over-the-Counter (OTC) reading glasses in the +1.00 to +1.50 range to help you read, but try to use them as little as possible.


Excuse 07 Feb 2015, 06:08

Hi all,

I'm 27 and have had weak glasses since I was about 17 (the optician said I didn't need them they were -0.25 and -0.5 with 0.5 astigmatism). Later I got stronger but still not at all strong ones (-0.5 and -1).

Anyway nobody knows about the glasses because, although all I want to do is wear them full time, I'm too scared to wear the weak ones in case someone noticed how weak they are and comments (my dad actually dud this). Plus I want to wear a stronger prescription anyway.

So what I am doing is getting stronger lenses online for my latest pair which I love and then new strong ones.

I've started planted seeds with friends. I'm telling them how i have on very bad eye and one good eye and I went to an optician and was given out to for not wearing my glasses full time and that the optician said my good eye was compensating so much for my bad eye. I'm thinking of wearing -1.5 left and -3 right with keeping the astigmatism and other bits the same

But i have a problem. For work I was just going to show up wearing glasses and just say I wear contacts normally. However just recently someone was having contact lens issues and asked me if I wore contacts. I said no and now I'm not so sure what excuse to give when I show up wearing glasses. I might have to phase them in over a month. Like drop hunts about how bad my eyesight is and have everyone see me wear them on occasion.

I want to know what you guys think is -3 a strong jump from -1? I think I can handle it after I tried on a friends glasses. And what am I to do about going from a non glasses or contacts wearer to a full time one. I really want to be wearing glasses full time with a mild to strong prescription - I know you guys understand these quirk.

Cactus Jack 06 Feb 2015, 18:23


In my previous post I mentioned the progression of presbyopia without explaining it. Presbyopia actually starts in childhood, but usually does not become a problem until the mid 30s or early 40s. When you are very young, your crystalline lenses have the consistency of gelatin dessert and your ciliary muscles can easily increase their power by more than +15 diopters. That is why you occasionally see young children coloring or reading with their eyes just a few cm from the paper. They can effortlessly focus very close.

As we age, our crystalline lenses gradually become stiffer and it is harder for the ciliary muscles to increase their power to focus close and ultimately you need external focusing help.

Right now, your ciliary muscles and crystalline lenses can supply the +6.50 to neutralize the -6.50 contacts for distance. To read normal sized text at a distance of 40 cm requires an additional +2.50 and your ciliary muscles are not strong enough to be able to supply it. The larger text on the iPad and the internal light source helps you be able to read. Hopefully, as your ciliary muscles get stronger, you may be able to focus on the smaller text in a regular book. When that occurs, you may be able to increase the power of the contact lenses to -7.00 or -7.50.


Cactus Jack 06 Feb 2015, 17:47


You may be able to go higher than -6.50, but it depends on how far your presbyopia has progressed (it varies with a person's genetic makeup) and the strength of your ciliary muscles. For their size, the ciliary muscles are the strongest muscles in the body, but they are really tiny. You can improve the conditioning of ciliary muscles by wearing over correction, but like any muscle building program, it takes time. If you try to condition the ciliary muscles too fast, they will complain and let you know that you need to slow down a bit.

i couldn't agree with you more. And working with a weaker prescription is much easier on the eyes, and in your friends case I am sure she is even able to see better with her glasses on than she sees without them and that is important because if her eyes are comfortable wearing glasses and her vision is improved she is much more likely to wear her glasses full time. And like your friend has found she enjoys the "buzz" of wearing glasses and being able to see better than 20/20 really helps with that feeling. Now it will be up to her if she is satisfied with remaining at wearing her -1.00 glasses or if she wishes to push it up more by wearing stronger glasses. But at least she has started off on the right foot for sure.

If you follow "olive's" comments you will see she is already wearing -4.00 / -3.75 glasses without any problem. So there would be little point in her going back to -1.00 glasses now.

Michael 06 Feb 2015, 07:10


I think the best way to get myopic are short steps and a lot of time.

Get glasses with -1 diopters and wear them a few month. I think your eyes will change to a weak myopia. So you get the ball rolling...

Then put lenses with -2 diopters in them and wear them all the time and do so on.


Likelenses 05 Feb 2015, 19:15


Another thing that is very important.Put your glasses on as soon as you open your eyes in the morning,and do not take them off until you go to bed at night.Do not take any time off without glasses.

With the type of work that you do,I would say that even at your age that you should be able to induce some myopia if you strictly follow these recommendations.

Likelenses 05 Feb 2015, 19:05


Here is an Asian optical company that sells online,and has a " special making department"

If you click on the second pair of glasses shown here, you will see that they are very thick,have plano,or flat fronts,and are only a -2.00 prescription.

Do you think that you would like to wear something like these?

I was also wondering the same thing as Soundmanpt,as to why if you do not need correction,you have a different power for each eye.

Also,some tips to do, to perhaps actually become myopic.

When reading or doing any close work be sure to always wear glasses,and hold the work as close to your eyes,as you can tolerate.When looking at distant things,such as menu boards at restaurants,or at a sporting event,or even watching TV,squint. These are things that myopic people do,that actually causes there myopia to worsen.

Revolver 05 Feb 2015, 12:49

Olive: there are a few other tricks that will give a huge appearances of thickness. First, use as big a frame as you can, and of course, CR-39 lenses. Get a prescription made, one way or the other, for plano base curve which isn't all that unusual and which will put all of the minus power on the backside making them thick at the edges. Finally, have them made up in safety prescription which has to be thicker in CR-39 to meet standards. You'll be pleasantly surprised. Not myodiscs, of course, but look very strong.

Soundmanpt 05 Feb 2015, 10:09


I am just curious, you said that you have perfect uncorrected vision but your able to wear glasses that are -4.00 / -3.75 all day long without any problem. Why did you order glasses with a different prescription for each eye? Now more recently you did the same thing with your recent glasses that have proven to be too much of a challenge to your eyes so far. Your just being a bit too aggressive, that's too big of a jump at one time. I suggest that you should order a pair of glasses with -5.00 lenses If your eyes have been comfortable wearing your -4.00 / -3.75 glasses then they should not have much of a problem adjusting to an extra -1.00. Just be sure that your eyes are fully adjusted to them before you start wearing them to drive with. Then after your eyes have gotten comfortable wearing -5.00 glasses you can take the next step up to -6.00. If your eyes can continue to accept the stronger prescriptions the next step will be the glasses you recently bought.

But I have to tell you that if your eyes are still perfect and your wearing -4.00 / -3.75 glasses on a daily basis and on top of that your a scripwriter meaning your doing mostly close all day long chances are your not going to become myopic. You didn't say when you started wearing glasses trying to become myopic but if you had started a few years sooner by now i think you would be myopic. But hey, look at it this way your eyes are allowing you to wear glasses with a very nice moderate prescription and your the only one that knows you don't really need glasses. You just have to remember that whenever you take your glasses off in front of anyone that you need to pretend that you can't see.

Olive 05 Feb 2015, 09:00


What a great idea? It sound nice to try, but I doubt that opt will give me such a thick lenses with that low prescription. Is there any suggest to become a real high myopia? I almost frustated ... None in my family wear glasses, it means that I don't have genes to become a myopia ... I work as scriptwriter and mostly spend my time in front of PC, but my eyes exactly have a good vision. Even I wear glasses with -4.00/ -3.75 from the time I wake up till go to sleep, my eyes still can see everything clearly without any blur ...

Likelenses 05 Feb 2015, 01:38


Another thing that you could do is have your -4.00 / -3.75 prescription made up using very thick lense blanks.

Many optical labs exist in Asian countries,so I am sure you could find one to make them for you.

You could explain that you want them for a part that you are playing for the theater,as an extremely myopic person.

I have seen glasses made like this and one would swear that they are a double digit prescription.

astigmaphile 04 Feb 2015, 23:55

Cactus Jack,

Thank you for clearing up my confusion about the names.

Cactus Jack 04 Feb 2015, 22:49

Astigmaphile and NJ,

Golden Man was the first person I helped. I have helped several others in similar situations, but because of those situations and the obvious risks, they typically contact me privately. Diamond Man contacted me several months after Golden Man was able to get an exemption. Unfortunately, all the private posts from Diamond Man are lost, but we have become rather good long distance friends.

I still occasionally hear from Golden Man. He later developed some serious, potentially life threatening, health problems that would have disqualified him from service for reasons other than vision. He apparently trusted me and asked my advice. I encouraged him to seek medical help, immediately, and to not be reluctant to do so. Fortunately, the health problems were diagnosed and are now controlled by medications and I believe he is doing well.

Because of the circumstances, I keep identities, if I know them, in absolute confidence. I sincerely hope that I can someday meet all of them in person.


astigmaphile 04 Feb 2015, 22:04

I think the persons name was Golden Man. He was looking for a way out of military service, I think. The first post that I could finf is 24 Aug 2008

NJ 04 Feb 2015, 20:32

CJ, I found no poster by the name of Diamond Man on this thread, searching back to 2002

Cactus Jack 04 Feb 2015, 18:29


The story is true and most of it played out in posts on ES under the name Diamond Man on the Induced Myopia thread, several years ago. If you go back to those posts far enough, you will understand the motivation. I had difficulty believing that he was able to accomplish what he did, but I do believe he did it.

There were several occasions when he "sweated blood" because he was subjected to repeated surprise dilated exams using the most powerful dilating agents available to check his vision to make sure he was not eligible for being conscripted.


NJ 04 Feb 2015, 12:31

Cactus Jack, that story really surprises me. The range of accommodation steadily declines with age, it's just that we don't notice it until we have less that a couple of diopters to spare. By age 25-30 we don't have anywhere near +13D of accommodative reserve. If indeed this person was able to induce this much myopia, I doubt it was entirely through accommodation and pseudomyopia.

Cactus Jack 04 Feb 2015, 09:38


I know of at least one highly motivated individual, a bit older than you are, who was able to increase his myopia from about -4.50 glasses to being able to wear -20.00 glasses, which translates to -15.50 contacts while studying normal text books. (contacts in that power only come in 0.50 increments)

What he was doing was conditioning and strengthening his ciliary muscles. His Axial or True Myopia was about -4.50 so he was ultimately able to use his ciliary muscles to be able to read while wearing -20.00 glasses. To calculate the additional PLUS his ciliary muscles and crystalline lenses had to produce to do that, you have to consider vertex distance effects of MINUS glasses and translate that prescription to the optical equivalent of contact lenses.

The calculation is pretty straight forward. Square the glasses prescription. Divide by 1000. That gives the vertex distance effect per mm. Then multiply that number by the distance from the cornea to the back surface of the glasses, typically 10 to 12 mm. Then subtract that number from the glasses prescription.

20 x 20 = 400/1000 = 0.4 diopters per mm x 12 = 4.8 -20 = -15,2 at the cornea.

If he had -4.50 of axial myopia his ciliary muscles and crystalline lenses had to create about +10.7 more PLUS to neutralize the additional MINUS for distance and about +13.20 to read at 40 cm or 16 inches. As I said, he was highly motivated.

There is not way to tell in advance what you can accomplish, There are too many variables. When you become comfortable and able to read normal text in good lighting conditions, you may want to increase the power of the contacts by a diopter or so. Small increases for longer periods seems to work best and are more easily tolerated.

It would be very helpful if I knew more about what you wanted to do. I have a feeling that you would like to wear glasses, but are perhaps reluctant for your friends and family to see you wearing glasses. If that is correct, we can help develop a strategy. It is all a mater of laying the ground work before you start wearing the glasses.

hi my guy 04 Feb 2015, 07:59

I'm working on some false myopia now. Hopefully inducing some over next few months. Been in cl of -6 and -6.5 glasses for a long time. I complained a bit at last eye appt and got a -6.5 and glasses at -7.25 3 months ago. Now just ordered -7 cl and ordered in -8 glasses in same exact zenni frame I got 3 months ago. And in 3 months intervals ill keep bumping up till next appt I will leave glasses at home and go in with the hi contacts (cause they don't measure them). So will have to rely on auto refractor for the starting point. I almost never go to same eye Dr twice back to back. So there is no preconceived starting point or final rx

Cactus Jack 02 Feb 2015, 22:40


Pseudo or False Myopia is different from Axial or True Myopia because Pseudo Myopia is caused by the ciliary muscles in the eye having difficulty relaxing after a long period of maintaining accommodation. You may have heard of Latent Hyperopia, it is also caused by the ciliary muscles having difficulty relaxing, sometimes after years of correcting hyperopia, internally.

The ciliary muscles are like any other muscles in the body, If you had to hold your arm in one position for a long time you might have trouble moving it from that position.

If you can see clearly for both distance and reading with your -6.50 contact lenses, you are maintaining quite a bit of stress on your ciliary muscles. Your ciliary muscles are squeezing your crystalline lenses to cause them to add the necessary PLUS to compensate for the MINUS in the contact lenses. Within reason, you want as much stress on the ciliary muscles as possible for as long as possible. Are you having any difficulty reading with the -6.50 contacts?

How much time it will take for your ciliary muscles to have difficulty relaxing depends on how much over correction you wear, how long you wear it, and your accommodation range. Presbyopia can sometimes play a role, but it is likely that you are too young for it to be much of a factor.

There is no way to predict how long it will take for for the over correction to have any semi=permanent effect. Expect to have to wear as much over correction as you can tolerate for many more months.

May I ask what your long term desires are? Would you prefer to be wearing glasses rather than contacts? There may be other ways to accomplish your objectives. If you would like to contact me privately, use

Thanks a lot Mr Cactus. Is theft any common period of time to índuce pseudo myopia? A lot of hears?

We need to move this conversation to the Glasses over Contacts (GOC) thread.

Please check there for my response.


 02 Feb 2015, 10:08


Age is a big factor in Inducing Myopia. If you have NOT developed myopia by your late teens or early 20s, it is likely that your genes will not allow your eyeballs to grow and develop any axial or true myopia. You might be able to develop some Pseudo Myopia, but it is not easy. Wearing -6.50 contacts is a good way to try, but it will take a lot longer than 2 months,

Eye damage is unlikely if the lenses are fitted so that proper tear action takes place including tear circulation UNDER the lenses. The corneas have no blood supply and must obtain their oxygen from the air or tear film. Also, proper care and hygiene is very important so you don't introduce infections into your eyes.

The main thing you are doing is exercising your ciliary muscles and crystalline lenses, which is actually a good thing.


Jacopo 02 Feb 2015, 07:36

Interessanty, because I haver the saem age (25) of the lady, and using minus -6,5 contact lens for almost 2 months. But no diference in my eyes! Impossible do índice myopia ta this age probably. Is there any possibilita of in damaging my eyes using such strong minus cls for a person that have 0.00 myopia as I and the sweet lady here?

Olive 02 Feb 2015, 02:33

Cactus Jack,

Thanks a lot for your suggestion.

So sad to know that in my age is difficult to induce myopia.

GOC? I never experienced it before, but it sound nice to do.

So, what plus prescription of contact lenses I should wear, in order to wear -7/-6.75 minus glasses comfortly?

Cactus Jack 01 Feb 2015, 21:25


At 25 you probably have enough accommodation to correct for the -3.75/-4.00 glasses, but not enough to be able to wear the -6.75/-7.00 glasses. It is likely that you will NOT be able to Induce much myopia at your age.

You should consider GOC. Wearing PLUS contact lenses will allow you to wear almost any minus prescription glasses you want to. However, there are several things you need to do to be able to do GOC comfortably and safely.

Properly done, GOC will allow you to have full accommodation range and wear high minus glasses without using up your accommodation to compensate for the excess minus.

If you are interested in doing GOC, let us know and we will help you avoid costly and / or dangerous mistakes.


Olive 01 Feb 2015, 14:36

Hi everyone,

I feel obsessed to wear strong glasses. I don't know why, everytime I see the girls in glasses with thick lenses and multiple rings,I really want to be one of them. It'd be nice if I have a myopia with -10 dpt. I have no myopia (0.00) but I wear glasses with prescription -4/-3.75 all days long. Even I wear that glasses everytime, my eyes still have good vision. Its exactly makes me frustated. So, I decide to make a new pair of glasses with prescription -7.00/ -6.75, but I can't see anything clearly with it. Everything's blur. I wanna wear my new glasses fulltime, but I don't wanna take a risk to drive with it on my nose. I really love to wear thick glasses, but still don't have any idea how to become a real high myopic.

Sorry for my bad English (English is not my first language). I'm from Southeast Asia, 25yo, Female, scriptwriter.

Cactus Jack 31 Jan 2015, 13:23


If you are really slightly short sighted, it is unlikely that you will need plus glasses when you are older. The reason that many older people need plus glass is that they were hyperopic to start with,

Unlike myopia, mild to moderate hyperopia is the ONLY eye condition that can be corrected by using the internal capabilities of the eye. The eye's internal auto-focus mechanism, consisting of the crystalline lenses and ciliary muscles, can typically correct hyperopia by adding plus to correct the problem. Often, with out their being aware that it is happening. It is not uncommon for these people to extol the excellence of their vision to others, particularly to those who are myopic or near sighted. They usually experience a very rude shock when presbyopia not only eliminates their ability to focus close, but also eliminates their superior distance vision.

You are not doing yourself any favors by NOT wearing correction for your mild myopia and as Soundmanpt said, if you would like to wear a bit stronger glasses, you most likely can wear up to -1.50 additional in each eye and once you get used to that, increase it even more. The slightly stronger minus glasses will actually have the same optical effect as being a bit hyperopic. Your ciliary muscles and crystalline lenses should be able to correct that, easily.

If you will supply your most recent actual prescription, we can help you order some slightly stronger glasses from Zenni. The important thing is to ONLY increase the Sphere correction by the same amount in each eye and copy the cylinder and axis EXACTLY in the new glasses you order.


Soundmanpt 31 Jan 2015, 12:56


Your nearing the age where if your wanting to try making yourself short sighted (nearsighted) you need to not waste another day. Time is running out. Most people's eyes start to become stable in their early 22's so that doesn't work in your favor at all.

I think your going to find it much easier to get started by just going straight to glasses and maybe start with -1.25 or -1.50 as a prescription since you already have a slight prescription already. Your eyes should at least be able to tolerate either of those prescriptions. But even more important is once you get your glasses it is critical that you wear your glasses every waking minute of the day from the time you open your eyes in the morning until you close them at night.

You didn't say what type of work you do but if it clerical work with intense close work that will greatly help.

I recommend getting your glasses from Zenni. (

Good luck!

I'm 26 and I have good vision -0.25 -0.50 both eyes and don't need glasses. I see a lot of People wear plus lenses glasses all the time when they are older. I don't like plus lenses in glasses and would rather be short sighted. Should I get contacts online and make myself -1.00 -1.50 so I don't end up far sighted. I wouldnt mind being shortsighted how much could I get to in the next few years? Then I would go to the opticians for a real prescription.

On the following page that is well knwon here, there is a story from 2010 called 'Myopia Injection'.

Is this possibly a method to really create myopia or is this fiction of the author?

I agree with Soundmanpt. I doubt that could cause any vision problems. May I as your current prescription, age and occupation?

No that would not be possible. Any changes in your vision has happened naturally.

Cactus jack, soundmanpt,

I have a tempurpedic pillow that i sleep with at night. As you probably know, these pillows are thicker than normal pillows. I just got it recently. Ive noticed after a month or so my vision has become blurry. I usually sleep face down. Could this extra pressure on my eye be increasing my astigmatism or nearsightedness?

PS: Today driving my car using my sister -6,50 cls i almost crash the car, because my (ciliary?) muscles ws extremely tired after doing a lot of fisical exercires, so my eyes didn't' adapt to the minus power, and everything stary blurry! i had to took of the lens to see and throw tem away. During the Day Im not having any trouble, but in the night I shall buy cls with a lower minus power

Thanks for your advices about the hight minus power, unfortanately I didn't listen you in time...

I found this site only this year, because in russian net I couldn't find any relevante information, If I already know the possibility of induce myopia or. pseudo, Ive already be trying.

But pseudo myopia could be continous in the long term, when the contacts be not been using anymore? Or during only when the minus power stay in the eyes?

Vladimir Nabokov

NJ 16 Dec 2014, 09:07

til, your English is great! Most native English speakers don't know the difference between presbyopia and hyperopia.

I'm not sure the effects of wearing over-corrected minus lenses on the onset of presbyopia has been studied. I'd think that the risk of increasing myopia would be too great, as it appears that close work and accommodation does have some effect on making myopia worse.

Wearing high plus glasses is definitely harder than wearing high minus glasses. The biggest difficulty is the near total lack of peripheral vision, and the higher the Rx the closer the blind area comes to the central visual field. One can compensate somewhat by turning one's head, but this is only partially helpful. Our peripheral vision is especially good at sensing movement, so that something coming in to our peripheral vision is immediately noticed even if it's not clear. With high plus lenses I am always bumping into things and people because they are out of my visual fields.

Cactus Jack 15 Dec 2014, 21:45


It might be better from a comfort point of view to be less aggressive, but If you can tolerate that much MINUS, it could be effective. Pseudo Myopia is caused by the ciliary muscles and crystalline lenses having difficulty relaxing. At 25 your crystalline lenses should be very flexible and you should be able to build the strength of your ciliary muscles.

Do you have any special reason for wanting to Induce Myopia or are you just curious about myopia?


Nabokov 15 Dec 2014, 19:03

Can I try to induce myopia at age 25 with a -6,5 cls? That my first option as my sister use this Rx. I'm using now for 3 weeks, and I can read pretty fine.

Is there any problem i a person with 0 myopia as I, use such strong minus lens?

And pseudoo myopia can happen withou minus lens, or only when I been using the lens?

til 15 Dec 2014, 17:34


Thank you for your answer. I see that I probably meant presbyopia instead of hyperopia, English is not my first language and I'm rather uneducated in optics.

You mentioned the hardening of the crystalline lenses to be a major factor in developing presbyopia, as many posts in this thread do. Bearing just this in mind was what got me thinking about the development of presbyopia. The following is just a thought: any biological process needs a reason to take place and cellular processes are determined by certain factors. And these processes, however they develop, will to a certain degree influence what is going to happen to your crystalline lenses (and supporting muscles) and at what point. If one (me) was to challenge these factors by having them work harder to compensate for an artificial minus lens, might that not influence their development?

I'm not sure if I really understood what you meant concerning your glasses, surely that self-prescribed reading segment helped you distinguishing close up from seeing far away, but why did your ecp at the time not notice?

Out of interest, I know some of the effects of wearing minus glasses over plus contact lenses, I have no experience the other way round though. What is it like concerning field of vision, peripheral vision and magnifying effects?

I did my best writing this, had three beers;-)

NJ 15 Dec 2014, 12:58

Sorry for the multiple posts....dunno why this happens.

NJ 15 Dec 2014, 12:58

Til, wearing minus lenses when you don't need them will probably only have a very modest effect on when you'll need reading glasses. Presbyopia is mainly caused by hardening of the crystalline lens, and muscle strength only gets you so far. At age 26 you have a lot of accommodative reserve so you can get away with over-minused glasses.

That said, I wore low-medium plus glasses in college and grad school, with a bifocal add that I included without my doctor's knowledge. I found that by age 30 I noticed an actual difference in my near vision with the add. And certainly by 40 I was totally dependent on the bifocal segment. I also started doing GoC in my mid-20's with very high plus glasses over minus contacts. I found almost from the get go that I needed the reading add, that I couldn't really see up close without it. I don't know if I was destined to be an early presbyope, but certainly by my 30's I was getting an add prescribed by the doc every time I had a refraction, and I wasn't even trying to fake it.

So maybe there's an effect, but I can't imagine it is very large.

Following a discussion i had with my girlfriend this weekend I was wondering about a few things.

From previous posts in this thread one can read that there have been several people who wanted to induce myopia in order to prevent themselves from needing reading glasses at a later point in their life. Apparently that can work in some cases.

Now I was asking myself is the same effect can occur without inducing myopia but only training your 'accommodation skills'. I have been wearing minus glasses in different strengths over the past year and have not observed any change in my visual abilities. Last week I had a full exam and ended up without a prescription. I'm wearing -1.75 full time and sometimes -4. My accommodation with the stronger pair gets better constantly, I can read almost comfortably at 25 cm. May this actually help preventing hyperopia?

I'm 26, male, spend 25% of my day in front of computers.

Thanks for your input

Cactus Jack 12 Dec 2014, 22:37


It is not possible to induce hyperopia in any form. The optical system of the eye consist of 4 lenses. Three of the lenses are fixed or semi fixed focus and only the crystalline lens is variable focus under the control of the ciliary muscles. All the lenses are PLUS and the total is actually around +55 to +60 diopters. If you use the formula developed by Sir Isaac Newton about 300 years ago, that much PLUS is required to focus distant objects on the retina located about 17 mm behind the crystalline lens.

The crystalline lens has a relaxed power (for distance) of about +15 and the ciliary muscles can squeeze the crystalline lens to increase its PLUS power for focusing close. The amount of extra PLUS the ciliary muscles can produce depends on your age, genetic makeup, and the flexibility of your crystalline lenses. The flexibility of your crystalline lenses depends on how far Presbyopia has progressed. There is no way to reduce the PLUS power of the crystalline lenses beyond their fully relaxed minimum PLUS for distance.

Of the 4 common refractive errors of the eye: Myopia, Hyperopia, Astigmatism, and Presbyopia, only Hyperopia can be corrected internally using the crystalline lenses. In understanding refractive errors and their correction you have to consider that the corrective lenses neutralize or cancel out the actual refractive errors so the end result is a refractive error of 0.00. If a person has Myopia, it means that his eye’s lens system has too much total PLUS to focus distant images on the retina. The solution is an external MINUS lens to neutralize the excess PLUS because the crystalline lenses cannot relax beyond fully relaxed. If a person has Hyperopia, that means that he does not have enough PLUS to focus distant images on the retina, but in this one instance, he can use his ciliary muscles to supply additional PLUS internally to focus the images on the retina and in many instances, if Presbyopia has not advanced too much, can even add more PLUS internally to focus on close objects. Often, the fact that this is occurring is not even noticed.

Latent Hyperopia is a condition where a person has used his ciliary muscles to ADD the PLUS needed to focus for so long, that the ciliary muscles and crystalline lenses can no longer fully relax very quickly. That does not mean that they cannot eventually fully relax, but if a person has Latent or Hidden Hyperopia and starts wearing external PLUS glasses or contact, the relaxation process can take weeks or months to occur. While that is occurring, the amount of PLUS needed in glasses or contacts will gradually increase until the crystalline lenses reach their MINIMUM PLUS power.

Latent Hyperopia and Pseudo Myopia are actually the same thing. If a person wears MINUS over correction, the ciliary muscles and crystalline lenses can ADD PLUS power to neutralize the excess minus. If they do that long enough, the ciliary muscles and crystalline lenses will have difficulty relaxing back to MINIMUM PLUS power and minus external lenses will be required.

To induce Hyperopia, it would be necessary for the total PLUS power of the eye’s lens system to DECREASE or the distance from the back of the crystalline lens to the retina to DECREASE. Neither one is possible because the structures cannot shrink. Growth is a one way process.

To create Hyperopia, you must REDUCE the total PLUS power of the eye’s lens system. You can do that with MINUS contact lenses or refractive surgery of some sort. If you want to get really serious about wearing high PLUS glasses, you can consider having your crystalline lenses removed, as in cataract surgery, but not replaced by IOLs, as is typically done. Internal Contact Lenses are also a possibility. They have the advantage that they can be removed whereas crystalline lens removal is permanent.

Hope this helps

Jdug, I used to be a natural +2.5 or so and found that I could go up to about +3.75 on occasion, though no doc ever gave me this Rx. However, I was not able to maintain the higher Rx and found that much of the time it was too strong. The eye has some natural variation in focusing power, so at times I could stand a higher Rx but it never lasted. And when I did GOC with high plus glasses I found that my natural Rx became higher during the day, so much so at times that it was hard to see after I took out my CLs without looking through the bifocal segment in my regular glasses. But again, the effect was transient and not easily reproduced.

Is it possible to produce latent Hyperopia? I've been doing GoC for a while and have found that I really enjoy wearing plus lenses more than minus lenses (I have near perfect vision). When I wear my -2.5 contacts, I can see just fine, but that is not the case when wearing +2.5 contacts. There's not a way to train your eye to slowly increase a plus contact prescription is there?

Cactus Jack 12 Dec 2014, 07:20


At 30, you should have plenty of accommodation available to adapt to wearing sphere -2.25 over correction. Rather than wearing her glasses, which may or may not have the correction for astigmatism you need or don't need, it would be better to order an inexpensive pair of glasses from and online retailer such as Zenni. If you will provide your complete prescription Sphere, Cylinder, and Axis, we can help you put together an order. Depending on the frame and options, Zenni offers glasses from US$7.00 and the quality is very good. Everyone is different, but I suspect you can adapt to wearing the stronger glasses in a few weeks if you wear them full time. If you order very similar frames to the ones you are presently wearing, few people will notice that you have new glasses.

It is highly unlikely that you will induce any Axial or True Myopia, but Pseudo Myopia will have the same effect, it just is not permanent. Not permanent is a relative term that in this instance means forever. Pseudo Myopia is the same phenomenon as Latent Hyperopia it is just on the other side of 0.00. If you wear significant minus over correction long enough, it can take weeks or months of wearing a reduced prescription for your eyes to revert to their natural prescription. The degree of permanence is related to your age and the amount of over correction. Presbyopia can play a role in how permanent.


Frank 12 Dec 2014, 01:33

Actually my prescription is -0.75 dpt. I tried my girlfriend's glasses with -3.0 dpt. I would like to wear these glasses fulltime. How long did it take your eyes to adapt? P. S. I am 30

Likelenses 08 Dec 2014, 23:35


I would bump the Rx up to -.75 for each eye,and wear the glasses full time.

Put them on as soon as you open your eyes in the morning,and remove them only when you go to bed at night.

Do as much reading,and close work with the glasses on,and hold the work as close to your eyes as you can tolerate.

Even if you see things in the distance clearly,squint to try to see them better.Example would be TV,menu boards in fast food places,traffic and road signs when driving.

These are all of the habits that nearsighted people have,which actually contributes to their condition.

Alyssa 08 Dec 2014, 22:16

So I got an eye exam last week and I am very upset with results!!

Last December my script was:

Right. -.25sph -.75cyl (120°)

Left. -.25sph. -1cyl (70°)

Last weeks script:

Right. +.25 -.5cyl (120°)

Left. +.25 -1cyl (72°)

i was hoping for a minus increase! I wear my glasses for distance.

How could this be? and should I bump my old scoot to -.5 sph to try to reverse this??

The doctor kept saying it will help with close work, your in your 30s now. when I can see just fine upclose. I can hold my phone super close and no problems, I don't get it. Distance is the issue from the astigmatism. I've never had problems up close. Do you think he just wanted me to get new glasses, so bumped me to positives.

NJ 03 Dec 2014, 14:49

Your question reminded me of the time I tried to fake myopia at the optometrist when I was in my teens. I did OK claiming that I couldn't see the eye chart, and even when he started to ratchet up the minus power I could keep up. However, it got problematic when he started making small changes and I couldn't tell which way he was going with the power. Frustrated, he projected a slide show of photos and just asked me to look at them as he played around with the lens powers and simultaneously looked into my eye with an ophthalmoscope. After five minutes or so he stopped and told me that he was able to take my power down to no correction, and suggested I has pseudomyopia. He asked if I had a lot of stress in my life ( did), then suggested I come back in the morning to try again.

The next day he made up some psychological explanation for my pseudomyopia, tried the refraction again, then gave me a pair of lenses in a trail frame and asked me to walk around, look at things, and see how the vision was. They were fairly low minus and I told him I could see great. He then made me a pair that I picked up a week or two later.

Funny thing though. I tried wearing the glasses but they were quite annoying. I didn't realize at the time that I had a fair amount of latent hyperopia that made me struggle with the minus glasses. I found this out in college, when I really did struggle to see and got my first pair of real glasses with a +2.50 cyl correction. And just for fun, I added a bifocal segment before getting the Rx filled. Been in glasses ever since!

NJ 03 Dec 2014, 14:39

Kiki, I think the challenge is to keep your eyes focused at a constant focal length without a subject to focus on. The autorefractor won't take a reading until your focus is steady, which I'd think would be difficult to do unless you have something to actually focus on. Would be fun to try though!

Crystal Veil 03 Dec 2014, 14:25

Nice idea, Kiki. I will leave the answer to Eye Scene members who are more knowledgeable on this, but you just gave me an idea for a photo shoot. I don't have an autorefractor but I use a trial frame with trial lenses occasionally. It may be a theme that could be used in one of my next photo shoots. Thank you!

I thought of something recently... What if a person posed as a college student who was doing research on the accuracy of an auto refractor. It would be cool to be able to spend some time manipulating your eyes to see what the machine says! Does anyone know if it actually works to show myopia by blurring your vision?

Cactus Jack 21 Nov 2014, 08:47


Many countries add the sphere and cylinder powers together to determine eligibility for military service. The primary reason they put a limit on refractive error is because without vision correction you cannot function and do your job.

I have been able to help several people in your situation, but it takes a lot of work and effort on your part.

I may be able to offer some suggestions, but I need some additional information. The most important is your age and occupation. If you are a student, what you are studying. If you are reluctant to be specific about your occupation or studies, it would help if you could give me a general idea.

You may also contact me privately at if you wish.

Hello all,

I have force military service and I really do not wish to serve as I have a mother who is in need of care and my two other brothers have deserted us.

My country doesn't give a damn of course.

The only way I could evade this if I was found medically unfit for service, the only thing I could think of is my eyes..

My current eyes prescription (Right: Sphere = -0.5, Cylinder=-3.5 Angle=170) (Left: Sphere:-3.25, Cylinder:-2 Angle=5)

The current rule for being unfit is that one eye is more than -4 for nearsightedness.

The dr does the test by using a lens (I'm assuming its lso -4) and dropping a light in your eyes and see the reflection and then determine if you're more than -4 or whtever he's looking for.

My question is, is there anything I could do whether by overcorrection or undercorrection in order to fool this test and actually make him see what he is looking to see inorder to be considered unfit?

Thanks in advance

Also it is important to adopt the habits that a myopic person has. When reading hold the work as close as you can to your eyes,even if it is not comfortable.Also squint when looking at something in the distance. An example would be a menu board at a fast food restaurant.

Try to read a book or newspaper at close distance,with glasses on for at least an hour a day.Be sure the distance is less than 12 inches. The closer the better.Every few weeks pull it closer if you can.

And as Soundmanpt stated leave the glasses on.Wear them as though you could not see well without them,and eventually that will happen.

Soundmanpt 14 Nov 2014, 12:49


In order to induce myopia your eyes are going to need to be stressed at least a little. meaning it is normal that your eyes may be uncomfortable wearing your glasses at first. But with constant wear you will start to notice that your glasses will start to become more and more comfortable for your eyes. It is also normal that your close vision is going to be bothered more than your distance vision will be at first. But I agree with Cactus Jack that your being a bit too aggressive and really should order a pair of glasses in -1.00 to start with. In fact since you already have a pair from Zenni by ordering the exact same glasses but with the weaker prescription once your eyes adjust to the -1.00 glasses and your ready to take the next step then you can start wearing the ones you have now with no questions asked. Of course by reducing the prescription its going to make it much easier for you focus with them and still be enough stress on your eyes to make them work harder.

If you read back in this thread you will see that it is most important that as soon as you open your eyes each morning the first thing you do is pout on your glasses and aside from maybe a necessary cleaning of them once or twice during the day you keep them on until your closing your eyes to go to sleep each night.

Rega 14 Nov 2014, 00:06

Cactus Jack

I alredy have a few sets of glasses with sphere only from online shops.

I have problems to read comfortably with -1.5D and my eyes are tired after wearing them for couple of hours.

As I mentioned before I can not wear contacts and I would like to wear glasses with thick edges. Id would be perfect if except the prism I could add some minus sphere to it.

Soundmanpt 13 Nov 2014, 12:42


Yes because what if you were to develope cataracts? That is the procedure they would use in that case even after PRK

But good luck actually finding a doctor to preform it for you and when you do i'm sure you must know that no insurance would ever pay a dime on it.

But if your determined to spend that much money just so your able to once again wear glasses than go for it. You do understand that any of these types of things you do to your eyes is going to be noticed by your current ECP when you go for an eye exam. It's not going to fool him or her. So really any doctor is going to wonder what your doing when they are refracting your eyes for glasses. Because they will be able to see that you had PRK as well as a lens implant. How are you going to explain that when they ask?

Now of course if you know exactly what the plus you have inserted then of course you can always get your glasses on line in the exact same power except in a minus. But at some point in your life your likely to start needing help with seeing up close, So now you will be seeing a doctor while not only wearing glasses for distance, but also having clearly had PRK and wearing a lens implant. That should confuse the hell out of that poor doctor. lol

Lalau 13 Nov 2014, 12:12

A plus ICLS implant procedure can be done after PRK laser? Or is there any risk.?

Soundmanpt 13 Nov 2014, 10:54


There are some medicines on the market that even has "blurred vision" listed as a side effect, however side effects means it is possible for blurred vision or some other problem to happen but not a sure thing.

But before you go to another country and spend many thousands of dollars in your effort to blur your vision so you will once again need to wear glasses. The best way is already at hand since your eyes are having no problems at all wearing contacts that are -4.75 on a daily basis. It would be completely different if your eyes were unable to wear hardly any correction then of course you would need to find a way for your true eyesight to be compremised. But for anyone wanting to return to glasses after having lasik the ones side effect is that it is not at all uncommon for ones vision to once again become myopic after a short time. This is why they offer the "touch-up" program because it is an issue and there is no way to tell if this is going to happen or not. So no one would even question you if you were to start wearing glasses tomorrow. Almost everyone knows someone that has gone back to glasses after having surgery and some do get the "touch-up" but others don't bother with it since their new glasses are usually not nearly as strong as the ones they had before surgery. But of course you wouldn't want to start off wearing -4.75 glasses at first. But I think you would be quite happy being able to wear -1.50 and later on bump it up to -2.00 or something your comfortable with wearing.

Cactus Jack 13 Nov 2014, 05:45


Try the -2.00 glasses without any prism. Your ability to wear -2.00 with low hyperopia depends on your AGE and accommodation range. Your ciliary muscles and crystalline lenses will have to supply +2.50 to compensate for distance and +2.50 more to read at 40 cm or 16 inches with the -2.00 glasses.

Can you read comfortably now, with out your glasses?

I would consider ordering some low cost -1.00 glasses from Zenni and see how those work before trying anything more ambitious.

Would be much easier if any cientist discover a hormône or something that índuce a bad vision, a myopia or other alteration, maybe in the future? We will see

I was talking with Master Cactus by email, and he said that believes in hyopnoses can induce myopia, wow! How mistéry isthe Human brain

Lalau 10 Nov 2014, 20:44

Thanks, but The ICLS implant alterate anything in the córnea? Or just the cristaline? I talked with a eyesceners that put a very strong plus ICL to back to myopia after lasik laser procedure. He made in Índia

I should think a lot and find a ophtamolomologist in the future if I still decided to conclude these plans. Im really thinking in the long term.(10 years) until There Maybe appear a new way to adquire myopia... it sounds crazy but web neves know.

If not and I still decided to do, I will see if my córnea allow any alteration to aquire myopia. I definetely have no worry to back to glasses.

Soundmanpt 10 Nov 2014, 16:52


As it seems with the desire you have now to be back wearing glasses that you really need, its too bad you didn't get lens implants instead of lasik. That way they could just remove the lenses and you would have your old uncorrected vision back and even be able to wear your glasses from before as well.

I have seen a few in here that have claimed they had or found sources to get surgery to allow them to wear glasses. But most if not all of them were people that had perfect vision. But if your corneas are still very good then your eyes could probably be changed by surgery. However I assume you know the cost for that could be even more then you paid for your orginal surgery. I am not sure this is a good idea even if your able to find someone.

I am not sure why you feel like your vision needs to really blurry for you to be able to wear glasses? You already know your eyes are more than able to tolerate a prescription of -4.75 which is quite strong and you would be the only one that woul ever know that you really don't need your glasses because your eyes are still seeing perfect. This way your not doing any damage to your eeys and if later on you decide that you don't like wearing glasses anymore, like you must have decided before which is why you had lasik inthe forst place so you need glasses anymore, this way you only need to stop wearing them if didn't want to.

Lalau 08 Nov 2014, 12:40

I undestand, what causes pseudo myopia and who are more able to aquire? Sorry the stupid quastion

Soundmanpt, what is your opinion about ICLS's to back to glasses? Or even a refractive cirurgy? If a remake it is a possibility to correct any myopia for the those who already pass into laser, maybe it is a possibility to reinduce myopia, reshaping the córnea again. My córnea as extremely thick acording to my ophtalmologist. Many eyesceners already done a cirurgical procedire to go to glasses.

I will study All the possibilities.

Soundmanpt 07 Nov 2014, 18:02


That is fine to do if you wish however if you have been wearing either the -2.75 or -4.75 contacts everyday from the time you open your eyes each day for the past 9 months your eyes are not going to be changed by increasing to -6.00 contacts. Its good that your eyes are still able to tolerate even the -2.75 contacts so well let alone even stronger ones. And to be honest your very lucky that your eyes can accept that much over correction considering you have perfect vision now. Your family genes now means nothing because the PRK already fixed what your family genes did to your eyes. You had them to thank for your vision when it was -2.75 / -3.25.

It's fine if you want to try wearing -6.00 contacts for the next 3 months if your eyes are able to tolerate the power, but then you better have a good story ready so you can order glasses and start wearing them or just accept the fact that your eyes are past the point of being changed and are locked in where there at.

Lalau 07 Nov 2014, 14:43

Thanks soundmanpt, Just for conclude my test I will keep using the cls for 3 months to complet 1 year of experiment. After that period I will study what I can do to Back to glasses

Next shoot will be -6,00 lens, the stronger power would help me more than the lowest RX, or that doesn't make any sense? I'm using -2,75 at the momento, I used -4,75 for 5 months, and no problems at All.

I was not very excited with the possibility of aquire miopia, but I was a little bit confident that I was Able to induce some pseudo myopia. If anybody would awnser me why I failed I would be extremely gratefull.

Obs: Age: 24 years

Rx Before PRK: -2,75/-3,25

Familiar tendence to myopia: Almost All the family (mother, father, brothers, etc)


Soundmanpt 07 Nov 2014, 10:49


It is not uncommon at all for a good number that have had lasik surgery to once again become short sighted after just a few years. This occurs because the eyes weren't completely stable when they had the surgery. This is why most doctors won't do the surgery until your eyes have been stable for at least 18 months. However some will do it after just a year. For that reason many places give a warranty and will do what they call a "Touch-Up" meaning they will do the surgery again to bring your vision back to 20/20 yet again. But in many cases either people don't do as they were told by returning every year to have their eyes checked out or they don't want to have the surgery again. So your worrying far too much about what people might think that knows you had the surgery. Also very few places actually give you a copy of your prescription unless you ask for it so not having a written prescription slip to show people would be normal. But of course you can't go out and order -4.50 glasses and start wearing them right away because that someone might question how your eyes so bad so fast that you would need glasses that strong already. For that reason you would need to start off with a much weaker prescription than I know your eyes can tolerate. For that reason your first glasses shouldn't be any stronger than around -1.00.

If your eyes have not had any change in the 9 months you have been wearing pretty strong contacts then clearly your not going to induce any kind of myopia. So if you want to wear glasses its time you start wearing glasses and just insist that your vision changed. It does happen after all.

Rega 07 Nov 2014, 10:45

Hello. I would like to order online glasses with 5 BO prism each eye. It is easy to get this prescription and I like the thickness of outer edge. I am happy to wear them full time so prism dependency is not the problem for me.

I am wondering how much can I increase the sphere value in my prescription? I am slightly hyperopic +0.5D and I am 36 years old.

The second question is: If I reduce the pupil distance in prescription with prism is it going to be the same like using higher value prism?

BTW. I can not wearing contacts so GOC is not for me

thank you


Crystal Veil 06 Nov 2014, 17:57

sorry for pressing the wrong button.

Twenty years ago, I had a relation with a lady in Dublin with a glasses prescription of +7.50 for long distance. She was 36 at the time and I often noticed that she pushed her glasses a bit further down her nose when reading. When I asked her why she did this, her answer was that it made reading easier for her as she saw the text slightly magnified. Her optician had refused to give her bifocals because he thought that she was too young for that. When she came to stay with me in Holland for a couple of weeks, I took her to my own optician and she got a pair of bifocals in her own prescription with an add of +1.25. It took her a year to get used to the bifocals as she had to unlearn her habit of pushing the glasses up and down her nose.

Lalau 06 Nov 2014, 17:45

Thanks, actually I don't think so I can cheat, because I'm the case of Laser cirurgy posted a few months ago. If I back to glasses would strange and wouldn't explain the reason for that without a true myopia prescription.

I thought I would be able to induce some pseudo myopia, I heard cases of people in their 20's that develop myopia, someone of those helped by Cactus Jack. Is there anything that makes Pseudo myopia continues even when the glasses/contacts are out of eyes? Is there any strategy to realize that? I read Cactus saying anything like that some post before.

Crystal Veil 06 Nov 2014, 17:43

Soundmanpt 06 Nov 2014, 16:50


It could be that because your 24 your eyes have become very stable and you may not be able to induce any myopia.

But if your eyes aren't having any problem wearing contacts as strong as you have been wearing them then I think instead of fighting it any longer you probably should just order yourself some glasses in the -1.00 area and tell everyone that you recently found that your vision had become slightly blurry and you now need to wear glasses. You could even say that you also have some astigmatism and you were told that you need to wear your glasses full time. Then after a few months order new glasses closer to -2.00 and only tell anyone that asks that you were told that your eyes could still get a bit worse and they did. As you know right now your just wasting precious time that you could be already wearing glasses. You don't know how long your eyes will be able to tolerate glasses with that much over correction.

Lalau 06 Nov 2014, 16:40

Hi guys, I've been trying to induce myopia for 9 months or something. I've been using contact lens of -2,75 and -4,75 using All day along, and reading with those

No diference in my RX until now, I went to my ophtalmology last week, and he sad there is no myopia.

At this moment it should appear any pseudo myopia right?

I'm with 24 years and started to try induce with 24 too

Cactus Jack 05 Nov 2014, 14:47


Please don't make assumptions. They will lead you to the wrong conclusions. You CAN induce some Pseudo Myopia, but you cannot do it in a few minutes or a few days by wearing a very small overcorrection.

As you may recall, in previous posts I said Latent Hyperipia and Pseudo Myopia were actually the same phenomenon, just on a different side of 0.00 refractive error. Even young people, with uncorrected hyperopia, use their ciliary muscles and crystalline lenses to correct their hyperopia, often without being aware that they are doing it. If they do this long enough - sometimes for years - their ciliary muscles will become very used to maintaining pressure on their crystalline lenses that the muscles cannot easily relax. When they are finally fitted with external plus lenses to correct their hyperopia, it can take weeks or months for their ciliary muscles to relax and during this period, they will need more and more plus until their ciliary muscles and crystalline lenses fully relax.

To Induce Pseudo Myopia, you need to wear enough minus overcorrection for a long enough period so your ciliary muscles will get used to maintaining pressure on your crystalline lenses and forget how to relax. When you take the glasses or contacts off your ciliary muscles will only relax a little bit or preferably, not at all, so distant images will still be blurry when you wake up. It will not happen suddenly and the younger you are, the more aggressive you need to be if you want to Induce Pseudo Myopia. Casual efforts will not be effective.

Frankly, at this point, I don't think you are particularly motivated. You just want to talk about it.


Tino 04 Nov 2014, 06:48

@Cactus Jack

Many thank for your reply, I think you have answered my question sufficiently for my purpose anyway but, for completeness.

I'm looking through the bottom part of my old glasses which is +9.75

I had my crystaline lenses removed and replaced

My pre-surgery prescription was around -2

Since having the surgery my hyperopia has increased bu around +1.25 and the reading add has increased from +1.5 to +2.75.

I was under the impression that my prescription wouldn't change once my lenses had been replaced but, if it does, then I regard it as a bonus.

Any other input is gratefully received.

Thanks again

Todd 04 Nov 2014, 02:59

Cactus I will do this test

So pseudo myopia it happens only when I am using a glasses or contacts? Doesn't happen with free eyes? I would like to stay a blurry vision without glasses

Aprently this is impossible

cactus Jack 03 Nov 2014, 07:50


You did not mention if you are looking through the distance part of your glasses or through the reading part. I will assume, through the reading part.

Your absolute prescription in the reading part is +10.75. Vertex Distance (VD) effects for a +10.75 lens is approximately 0.12 diopters per mm. 3/4 inch is about 19 mm, so moving the +10.75 lens 19 mm away from your eye would have the effect of increasing the apparent power of the lens by +2.28 diopters. If you are looking through the +8.00 part of your lens the increase would only be +1.21.

I would suggest that you try some over the counter reading glasses to see what lens power you need to focus at your preferred reading distance.

A few questions:

1. How is your distance vision through the +8 part?

2. What was your prescription before surgery?

3. What procedure was done to make you hyperopic?

4. Were your crystalline lenses removed?


Tino 03 Nov 2014, 06:22

Sorry that last post was from me

 03 Nov 2014, 06:21

Apologies if this is the wrong thread but I've found recently that I need to move my glasses further from my eyes to magnify the print I'm trying to read. Is this simply a case of needing a stronger prescription for reading and intermediate use or something else? If it's a stronger prescription does anyone have an idea of what moving the lenses 3/4 inch further from my eyes equates to in terms of dioptres? I had surgery a year or so to give me around +8 for distance and already have an add of +2.75 for reading

Cactus Jack 02 Nov 2014, 17:00


If your Ciliary Muscles are capable of squeezing your Crystalline Lenses to increase their PLUS power from their relaxed state, You can Induce Pseudo Myopia. Pseudo Myopia is TEMPORARY, the only question is how long with the Pseudo Myopia persist.

Any time you wear MINUS glasses or contacts that have more MINUS than you need to correct you vision, you HAVE Induced Pseudo Myopia if your distance vision is clear and sharp. How much Pseudo Myopia you have induced depends on the amount of MINUS over correction in the glasses or contacts. If you are young and your crystalline lenses are flexible, when you take off the glasses with the over correction, your Ciliary Muscles will relax and your Crystalline Lenses will revert to their normal relaxed power in a fraction of a second, but while you were wearing the glasses with the excess MINUS, you had Induced Pseudo Myopia. The question then becomes "How do I make the Pseudo Myopia persist longer than a fraction of a second.

I would suggest that the first thing you need to do is check your accommodation range to get a base line reference. You can do this test with an ordinary book or newspaper with typical sized news print and a ruler.

Step 1. In reasonably bright light and in your case without any external correction, hold the book or newsprint about 50 cm from your eyes. You should be able to read the text easily.

Step 2. Move the text slowly toward your eyes until you simply cannot focus on the text. Don’t worry if you cannot keep the images fused. When the text gets fuzzy and you can no longer focus, measure the distance where you could no longer focus.

Step 3. Do this several times and average the distance.

Step 4. Divide the nearest distance into 100 cm and tell me the results of the test.

Could you get to the point where you could wear -20.00 glasses, I don’t know, but I doubt it. The problem is that after your refractive surgery, your distance vision is near 0 refractive error. To wear -20.00 glasses your Crystalline lenses would have to be able to supply approximately +15 extra diopters of PLUS power. Part of Inducing Pseudo Myopia is strengthening and conditioning your Ciliary Muscles - think of it as visual weight lifting. It may not be possible for your Ciliary Muscles to get strong enough. However, if you are willing to work hard, you might be able to achieve -14 or -15, but it will take time. -4 or -5 should be pretty easy to achieve in a short time, but it will take much longer for Pseudo Myopia to become persistent.

By the way, if you wish to contact me privately, use


Todd 02 Nov 2014, 13:23

Thank you Cactus.

Great explanations. The pseudo myopia will occur dependind of person or it happened in everyone, with no exceptions?

What's the limit there I should go for using minus lens? -20.00?


Cactus Jack 01 Nov 2014, 17:36


I find it interesting that several people who have had Lasik or other refractive surgery to correct myopia are now regretting the procedure. You have indicated a desire to induce some myopia. Perhaps I can help.

I have been able to coach some highly motivated people and help them develop significant Pseudo Myopia. In one instance the individual had Axial Myopia in the -4.50 range, but needed to increase his myopia significantly.

He was in his late 20s when we started and it took about a year to do it, but ultimately, he was wearing -20.00 glasses full time and was able to read with them for extended periods. The majority of his myopia was Pseudo Myopia, but he actually induced about 1 diopter of Axial Myopia.

Because of Vertex Distance Effects -20.00 glasses correct about -15.00 diopters of myopia at the cornea. Vertex Distance Effects are very small in glasses below about -4.50 and are often ignored so the total myopia he induced was about -11.50. The Pseudo Myopia he induced was not permanent, but it lasted long enough to accomplish his purpose. Once you have achieved Pseudo Myopia in the range you desire, you can likely maintain it by continuing to wear over correction.

You appear to have some understanding about what causes Myopia, but I will try to refresh your knowledge so you will understand the task ahead. Myopia is fundamentally a mismatch between the total power of your eye's lens system and the distance between the back of the crystalline lens and the retina. There are actually 4 lenses in your eye's lens system with a total power of around +56 diopters. Three of the lenses are fixed or semi-fixed power and One lens, the crystalline lens is variable power. This much optical power is needed to focus distant images on the Retina which is approximately 17 mm from the back of the crystalline lens. If the distance is more than 17 mm (eyeball has grown too long usually because of genetic factors) Axial Myopia results and distant images focus in front of the Retina. Minus lenses are used to move the image back to the retina. Another way to move the image back is to reduce the + power of the lens system. Because most body structures do not shrink once they have grown, Axial Myopia is considered permanent because the eyeballs generally do not shrink once they have achieved "optimum" size, unless genetic factors permit and specialized growth hormones (suspected to exist, but not proven) are produced that cause additional growth. It occurs, but it is very rare after around 20 years old.

Pseudo Myopia is actually the same optical phenomenon as Latent Hyperopia in that both involve the Crystalline Lens and the Ciliary Muscles. Pseudo Myopia can be induced at any age, up until Presbyopia makes the Crystalline Lens so stiff that the Ciliary Muscles can no longer alter the optical power of the Crystalline Lens.

Lets talk for a moment about how the Ciliary Muscles and Crystalline Lenses function. The eye is designed so the Crystalline Lens and Ciliary Muscles are fully relaxed for Distance Vision. Even when fully relaxed the Crystalline Lenses have significant + power, usually around +15 diopters. The Ciliary Muscles job is to squeeze the Crystalline Lens (which has a consistency of Gelatin Dessert) and increase its + Power for focusing close. Young children have extremely flexible Crystalline Lenses and typically have an accommodation range in excess of +10 diopters. That is why you see young children effortlessly focusing at distances of just a few cm. As you get older, the Crystalline Lenses become increasingly stiffer (Presbyopia actually starts in childhood) and finally, in your late 30s or 40s they become so stiff that the Ciliary Muscles can no longer focus them.

In the case of Hyperopia, many people are able to use their Ciliary Muscles and Crystalline Lenses to compensate by adding the extra + they need to focus clearly for distance and even the + need to focus for reading, internally. At some point Presbyopia catches up with them and they need external + correction. Unfortunately, a person with Myopia cannot relax their Crystalline Lenses beyond fully relaxed and they need - external correction or surgery.

The idea behind Inducing Pseudo Myopia is to wear substantially more - correction than you need to cause the Ciliary Muscles and Crystalline Lenses to compensate. If the over correction is high enough and you wear the glasses or contacts long enough, the Ciliary Muscles and Crystalline Lenses will have difficulty relaxing which is exactly what occurs naturally in Latent Hyperopia. If your Ciliary Muscles are stressed long enough, either from correcting Hyperopia or from Myopic Over Correction, they will have difficulty relaxing. It can often take weeks or months for a person with long term Latent Hyperopia to fully relax their Crystalline Lenses and be able to wear full correction in their glasses.

If you are serious about Inducing some Pseudo Myopia, I am willing to try to coach you, but I need some more information that you might not wish to share on ES. Please contact me privately at


Todd 31 Oct 2014, 22:53

My target it is back to my old -4.,0 myopia

But I think this this is not possible at all! Well, honestly.. If I induce half of that I would be very happy, because I could wear my original glasses without very many problems.

Todd 31 Oct 2014, 22:47

And that is the problem.. My Rx it is 0.0 probably.. I had -4,0 of myopia two years ago and dia a laser correction, but now I would like to back to glass. I read a similar case to mine, I thought I was the only person with that case.

So pseudo myopia will occur in everyone with 100% of certain? I just thinking this is too good to be true!


svensont 31 Oct 2014, 15:22


There is no rule when pseudo myopia will occur. It depends on many factors. It might take months, but you should start noticing difference soon, for example when you wake up and everything will be blurry.

Glasses and contacts are the same thing for inducing myopia.

What is your target RX?

Todd 31 Oct 2014, 14:47

Thanks my friend I started today the -0,75 contacts, no problem to see at all.

Todd 30 Oct 2014, 23:59

Thank you.

Well, so just let me see if I undestarnd 100% fine: In the 20's the chances of develop a true myopia it is very small, but a pseudo myopia it is possible right?

Everybody that uses a extra minus poder in their eyes will necessarily develop some pseudo myopia in the long term, independent of age?


Soundmanpt 30 Oct 2014, 17:13


The information given by Likelense is the same I would recommend to you. That is a very good starting point. If you also getting glasses you might want to get them in -1.00. That way as soon as your completely comfortable wearing the contacts you can start wearing the glasses. Then when you adjust to the glasses you can wear both the glasses and contacts together which would be equal to -1.75 and continue from there as long as your eyes are willing. Even if your unable to induce any true myopia your still young enough that you should be able to wear glasses in a decent prescription if you wish in complete comfort and no one will know that you can see perfectly without your glasses.

Todd 30 Oct 2014, 14:55

I have been reading some other posts, and I will start with -0,75, is there any limit there I should go for in contacts Rx? Like -5,00 -10,00 etc? Use minus contacts or glasses would be the same?

Can I develop axial/pseudo myopia without extremely close work? Just reading in normal distance(30cm + -). I suppose it is impossible to avoid astigmatism? My objetive it os aqcuire only myopia.

Thank you both

Likelenses 30 Oct 2014, 14:16


Start off with -.75 for each eye.

Put them on as soon as you wake up each morning,and leave them on all day,until you go to bed.

Do as much reading,and close work as you can,and hold the reading material closer than you normally do. About 8 to 10 inches away,same with the computer.

Squint if there is something that is not clear at near,or distance.

svensont 30 Oct 2014, 12:37


I have probably only some pseudo myopia, but I also "induced" astigmatism. My current prescription is L: -1.5 -1.25cyl, R: -2.0 -0.75cyl

My ymail is on yahoo, and it is (my nick)

Todd 30 Oct 2014, 12:12

Hi sventson, I'm from south america

Thanks for your explaination.Nice to hear that, so do you delevelop a pseudo or axial myopia? What tour actual Rx?

Maybe it should better talk with you by email, but I don't undestand.. It's a hotmail?

svensont 30 Oct 2014, 00:17


Where do you live and what is your occupation?

There are two types of myopia: axial and Pseudo. Axial is when your eyeballs are too long, so the optical power of the eyes is too much plus, and minus lenses are required to cancel that. Pseudo myopia is when ciliary muscles are unable to relax.

When you read something or look at something close your eyes are accommodating - increasing the plus power of the lens, and when you look at something in the distance they relax - decrease the power. At your age you should have about 8-10 dioptres of accommodation left. Now imagine that if your eyes are "locked" in the state when you look at something from the distance of 1m means that they increased the power of +1D and you will need to wear -1D to cancel that.

I started inducing myopia when I was 23 and now I need to wear glasses full time. I'm 26 now.

You can read older posts in this thread, especially from Cactus Jack to know more about the eyes, or contact me privately svensont(at)

Todd 29 Oct 2014, 23:05

I'm 0,0 right now, no myopia

Todd 29 Oct 2014, 23:04

Yes, my mother are -1,0 and father are -8,0

Sorry my ignorance, but what would be pseudo myopia?

svensont 29 Oct 2014, 10:32


The chances to induce true myopia are very low, but you can successfully induce some pseudo myopia. What is your current prescription? Is anyone in your family wearing glasses?

Todd 28 Oct 2014, 22:47

I'm 24 old guy, in that age it is still possible induce myopia? Maybe with a lot of close work dayly?

Btw I'm student


LXW 28 Sep 2014, 08:10


thanks you so much for your luck! I understand what you mean. Perhaps i will try to do it next year in may/june if i find a surgeon who will do this.

Brianwebber, i have sent you an mail. I am very interested to chat about your surgery!


brianwebber 24 Sep 2014, 01:22


Alex, I should have said, three and a half years ago I had the same elective surgery.


brianwebber 23 Sep 2014, 09:45


Alex if you are interested maybe we could chat about elective refractive surgery.

Cactus Jack 23 Sep 2014, 09:19


I wish you luck in finding a surgeon willing to do the procedure. One positive thing in your favor, the procedure is revisable by removing the lens, even though it involves a second surgery.

There is a joke here that the ONLY minor surgery is surgery on someone else. Even though the surgery is considered "minor", it is still surgery and you will be exposing your eyes to possible infections and complications. I suspect the surgeon will do one eye and then wait a few weeks to do the other, as they do with cataract surgery. Be sure and follow the pre and post operative requirements to the letter.

Please let us know how it works out.


LXW 23 Sep 2014, 08:45


thanks for your lines and the link, very interesting for me as i am a newbie... Also the -12dpt range sounds very good! But i go on reading everything i can get ;-)

I will do the procedure of inserting Visian ICL phakic lens into my eyes in europe. They write the following on their site: "The range of diopter that can be corrected with phakic lenses is from -20 to +10." And some lines below: "...there is also another type of phakic lens, VISIAN ICL, which goes behind the iris and in front of the natural lens, and that is the type of phakic lens that we use..." At the end of the article they write about the procedure and this: "The condition for the implantation of VISIAN phakic ICL lens is that the anterior chamber depth (distance from the posterior surface of the cornea to natural lens of the eye) is bigger than 2.8 mm."

Hope my chamber depth will be bigger and they do it to my eyes which have no refractive error. Please.


HighMyopic 16 Sep 2014, 10:54

Cactus Jack, I sent you a email about a question about a pair of -20 diopter glasses that I want to order for myself to wear.

Cactus Jack 11 Sep 2014, 05:08


If you could get a +10 ICL and your present refractive error was 0.00 that would give you approximately +10 diopters of refractive error at the cornea. With Vertex Distance effects, that would be corrected by glasses in the -12 range

I found an interesting article about ICLs on the Visan website about the two types of ICLs marketed in the US. The Visan ICLs are made by Starr Surgical.

In the article, near the end, the rage of corrections is listed as -3.00 to -20.00. However, that may apply ONLY to the US because the FDA will only allow that range of lenses to be implanted, here. I suspect the range of lenses that can be implanted between the Iris and the crystalline lens is limited by the maximum thickness of the lens. PLUS lenses are thicker in the center than MINUS lenses and there just is not much space available. A thicker (higher PLUS) ICL can be installed between the cornea and the iris.


 11 Sep 2014, 04:17


thanks a lot for your lines, i am happy to see that people want to help me! I understand all what you say and i know about PLUS or MINUS.

As i have written i have read a lot about IOL/ICL. And there is a site which writes exact the following about Visian ICL Phakic lenses: "The range of diopter that can be corrected with phakic lenses is from -20 to +10."

So my opinion was that i put the +10 ICL in both of my eyes and i am myopic from this point. I am wrong?

I want to be high myopic (for me it´s -10dpt or more) and i also want to keep the ability of accommodative in my eyes.

Any tipps are very welcome, thanks. Alex

Cactus Jack 10 Sep 2014, 09:28


Your idea of using theVisian ICL phakic lens is excellent except for one small detail. They are made only in MINUS powers for correcting myopia. To use them to surgically induce myopia would require PLUS power lenses.

Myopia can be described in many ways, but from a correction point of view, the myopic eye has too much PLUS in its lens system and a MINUS lens is required to reduce the excess PLUS power. To surgically induce Myopia, you need to increase the PLUS power of the eye's lens system. That can be done using a PLUS ICL between the cornea and the iris or by replacing the natural crystalline lens, which has a PLUS power of around +15 when relaxed with a stronger IOL with more PLUS power than your natural lens. Of course, when you replace the natural crystalline lens, you will loose any accommodative ability you have and will need either multi-focal IOLs (think hard about that choice), bifocals, trifocals, or progressives to see clearly at all distances.

Any Eye Care Professional will know that you have had any surgical correction because they know what to look for. The neat thing about IOLs is that you will never need cataract surgery, you have already had it. You may need to explain why you have high myopia after replacement of your crystalline lenses. Most people opt to have their myopia or hyperopia corrected when they have cataract surgery.


LXW 10 Sep 2014, 05:05


thanks for your words. I have read the following on a website regarding Phakic ICL/IOL: Q: Is the lens visible to others? A: No. The ICL is positioned behind the iris (the colored part of the eye), where it is invisible to both you and observers. Only your ophthalmologist will be able to tell that vision correction has taken place.

My thought was that only the doctor who put in the ICL can see it and no other... Perhaps i was wrong.

I don´t know much about "refractive surgery", but if it is an possibility i will do that instead of ICL. But is it reversible and are the costs like this from ICL?

Thanks. Alex

NJ 09 Sep 2014, 07:48

Choch, Sam is right. To become a high hyperope you just have your crystalline lenses removed. Of course, the optometrist will notice this too but it's easier to come up with a good story for why you don't have IOLs. It's have to explain having an ICL that induces -10D of myopia.

Varifocals 09 Sep 2014, 06:45

My wife has worn glasses since 11 full time as she is myopic, about -6 not too bad.

we married in glasses.

Anyway, she has had cataract surgery & is now long sighted.

At the moment I am a plussie, so as I have been told eventually I will have an operation too , wonder if I will end up myopic?

sam12744 09 Sep 2014, 04:59

I think he means you 'just' have your crystalline lenses removed a la cataract surgery.

choch 08 Sep 2014, 22:24


I must have missed something. how is hyperopia inducing easy?

NJ 08 Sep 2014, 16:29

Refractive surgery is also visible to an optometrist because the cornea is remodeled.

LXL have you considered to do a refractive cirurgy? it´s invisible for the others, I suppose.

NJ 08 Sep 2014, 12:36

LXW, an ICL or IOL is very visible to optometrists. There really is no way to become a high myope without something artificial in your eyes. Now if you wanted to be a high hyperope, that's easy.

LXW 08 Sep 2014, 11:33

Hello Cactus,

i also want implanted lenses to be high myopic. I want to use glasses or contacts after ICL is done. My gain ist to be shortsighted about -10dpt or higher.

But i have the same problem like other people: There is no clinic who will put Lenses in my eye. In germany (where i am from) there is no chance i think.

I have read a lot, and it´s not easy for me because it´s all in english.

There is something who sounds very interesting for me: "Visian ICL phakic lens". It´s a lens which is behind the Iris and in front of the natural lens. So it´s invisible for other people. And the procedure is reversible.

I think that sounds very good for me!

But my question is, are these lenses also invisible for optometrist? And who does this to my very good eyes??

Thanks a lot!


Cactus Jack 05 Sep 2014, 20:22


There are two possibilities for surgically increasing your myopia.

1. Implant an internal +7 "contact lens" between your cornea and the Iris of your eyes. This has the advantage of being alterable by removing and/or replacing the Internal "contact lens". This also has the advantage of retaining your crystalline lenses and whatever accommodation you have remaining at 35.

2. Get a clear lens replacement of your crystalline lens. This surgery is identical to cataract surgery and you have some options regarding the type of IOL that is implanted. This lens replaces your crystalline lens and is permanent for the rest of your life. This procedure has the advantage of never needing cataract surgery because it has already been done. However, it is possible that you will develop what are called by some as Secondary Cataracts.

Secondary Cataracts are not really cataracts, but are caused by the cells that make up the lens capsule or sack trying to regrow your crystalline lenses. Should this occur, all it takes to solve the problem is to use a special laser to burn away the center portion of the back membrane of the lens capsule or sack. The procedure is painless, takes about 10 minutes and that ends that problem for a life time.

It might be tempting to opt for multi-focal IOLs so you theoretically won't need bifocals or trifocals. However, multi-focal IOLs are not right for everyone. Single vision IOLs give the best vision, but you will probably need reading glasses, bifocals, trifocals, or progressives for close focusing.

If you decide on IOLs, you want to be sure the final prescription you select is what you want forever. There is no going back or changing it without major, very risky surgery to completely remover the lens capsule and IOL. After that, the only choice is very high plus glasses with all their limitations.

If you want to pursue IOLs, please contact me privately at and I will try to put you in contact with one of our members who recently had extreme myopic surgery.

Check with Dr. I Chopper in India.

vanq 05 Sep 2014, 18:47

Hello everyone !

I have been following this forum for a few years and even posted a few times anonymously in the past. Like quite a few here, I would like to become more myopic (-8 dpt) than I naturally am (-1). "Inducing myopia" by permanently wearing CLs or glasses that are stronger than necessary never really worked for me so far and given my age (>35) I do not think that I makes sense to try it any more. The only result are headaches if I try too much.

In the past couple of years, I have also been contacting quite a few clinics across Europe with a request to get IOLs with the equivalent of +7 implanted. I even managed to get invited for eye exams twice. In the end none of the clinics was however willing to perform the surgery for what they call "ethical reasons", despite the exams showing that surgery would technologically no problem at all.

It is really depressing. There seems to be no way to get what I want: being 24/7 dependent on glasses. If anyone is able to refer me to a clinic which would be able and willing to implant IOLs or laser me to at least beyond -3, I would really be thankful. (

Soundmanpt 04 Sep 2014, 10:55


What "John S" said is very true. You should consider getting an eye exam because even though you may feel like your vision is perfect an eye exam can sometimes prove otherwise. Exactly what John S is talking about is something the young lady that cuts my hair, what I have left anyway, found out not long ago when she went as part of being healthy. She went to her MD, her dentists and had her eyes examined. She was surprised to find that she actually has a prescription for reading glasses. The doctor told her that as long as her vision wasn't bothering her at this time she didn't need to get glasses, but at some point she will be needing reading glasses. She told me she does notice that if she is reading a book or magazine very long the words start to run together so she stops reading. She admitted that if she was working in an office type job where she was doing close work she would have to get glasses, but with cutting hair so far her eyes are fine for that.

John S 04 Sep 2014, 08:21


You cannot induce farsightedness. But many people are slightly farsighted and do not know it.

If you are farsighted, by constantly wearing plus lenses you might be able to cause the muscles in your eyes to relax and start to show the symptoms. The most effective way is to wear bifocals.

What is your age? Do you have any problems reading for long periods? Have you ever had an eye exam?

foureyes 04 Sep 2014, 03:35

hi i know this is a topic for inducing myopia but can you induce farsight as well as near sight and what method can be used to induce it,thanks

Lalau 29 Aug 2014, 18:53

Yes Sound, that I what I will going to say, actually I did it mut with my Brothers glasses.

Next week I will be back to post if is there any myopia, or this vision problem would be a other optic anomaly.

A nice weekend for everbody


Soundmanpt 29 Aug 2014, 16:22


When you go it will not hurt at all to comment that a friend recently got glasses and you tried them and found your vision to be slightly better with glasses.

I wear readers for fine print.

Lalau 29 Aug 2014, 12:32

Sound, thanks for you reinforced awnser.

I understand that is really almost impossible to say if my bad night vision is because of laser failure or a induced myopia. Maybe the first, and I didn´t notice ate the beginning.

Anyway if the doctors really can´t prove that I need a glass to night use, I will ask him to use one with low minus prescription. And to be honest, I will definetelly will not be lying to him.

I will continuous using minus cls for the next months, maybe 6 months or more. To complete 1 year of test of trying to induce myopia with minus extra power. Probably the final result could help us understand more about the eyes and possibility of indude myopia after 20´s, if in the end I could achieve any Rx increase. I will not create much expectations because of the small chances.. We will see.

Curious: Sound and Cactus: I suppose you both use glasses right?


Soundmanpt 29 Aug 2014, 12:03

Lalau and Cactus Jack

I can't say for sure about anything new, but I know in order to get a "touch-up" your vsion had to at least at -1.50. I think they use that number because that is about where many may begin to feel they need their glasses full time again. Anything less they assume as pert time wear.

Laalu is probably required to return every 12 months to get her eyes examined in order to keep up that warranty she likely got. Pretty much like buying a new car and having to take it in for annual check ups and to be sure you change the oil etc.

I am quite sure Lalau if you complain about problems seeing after dark you will be prescribed glasses for that without any problem. They simply can't test your eye under those conditions so they have to take your word for it. Thye will refract you at -.50 and have you read the eye chart and since your able to see with an even stronger rx than that you won't have any problem seeing with the -.50 lenses and that is what they will write you. Like Cactus said once you get a written script then it should be easy to increase the power by getting your glasses from Zenni.

Now of course all this is in case your vision is still perfect. But hard to say and maybe you have developed some myopia as a result of your actions with the contacts you have been wearing.

Lalau 29 Aug 2014, 08:51

Thanks for the explanation my friend

Next week I will go back to a ophtal. to make a exam and see if is there any myopia

Ill post the result here

PS: The reason that I want go back to glass is that I feel me better with them, and stetically I looks much better using it


Cactus Jack 29 Aug 2014, 01:06


It is just possible that you may have induced a tiny bit of myopia, that is only manifest under very dim lighting conditions, when you pupils are fully dilated. It is also possible that the "dim light" myopia is a bit of myopia that was not corrected by your surgery. You may need to go back to the ophthalmologist that did your surgery for a check up, but I would be surprised if you are given a prescription for glasses or contacts. You may get an offer for a touch up, but I suggest that you decline the offer. I hope the ophthalmologist who did your surgery is NOT a family member or family friend. That would be awkward.

I fully understand that you may be regretting having had refractive surgery. You are not the only person who has contacted me about wanting to induce some myopia after refractive surgery. Typically, ophthalmologists WILL NOT do refractive surgery until they are very sure that your prescription has stabilized and there will be very little risk of any natural increases in myopia. Increases which would require additional surgery or external correction. I usually don’t ask why a person wants to start wearing glasses again, because I believe it is none of my business. Perhaps it is a subject that should be explored under Psychology of Glasses.

I sense that you would like to have an OFFICIAL prescription for glasses from an Eye Care Professional for some reason, rather than just ordering some glasses from an on line retailer such as Zenni Optical, and start wearing them. If you want an OFFICIAL prescription for glasses from an Eye Care Professional, I think you would have better luck with an Optician or Optometrist. They may or may not recognize that you have had surgery, but that is not important. You need to complain that you are having trouble seeing clearly at night and you have tried your brother’s glasses and they help make everything at night clearer, particularly when driving. That may get you an OFFICIAL prescription and OFFICIAL permission to wear glasses when driving. Even if it is a very low prescription, you can then order glasses with that prescription or a stronger one if you want to, from an online retailer. As long as you keep the same frame style, no one will notice your prescription changes.

If nothing else, you may be able to get glasses prescribed for driving and once your friends and family get used to you wearing glasses again, part time, you can wear them more and more if you want to. If anyone asks about why you are wearing glasses again after your surgery, just say that there was a little residual myopia after your eyes healed that caused you trouble driving at night. The glasses solved that problem and you found that they gave you a bit sharper vision even in daylight and it was a nuisance to keep putting on the glasses to drive and taking them off when you were not driving. When you wear glasses all the time, you almost always know where they are. Full time wearers rarely misplace, loose, or damage their glasses by sitting on them.


Lalau 28 Aug 2014, 16:01

Thanks Sound and Cactus for the awnsers.

Well, I´ve researching fot others causes for my nocturne myopia, and yes I think is in fact a tiny myopia, that is percepltable only when my pupils are dilated in a very dark place. In adittion to this explanation, I found some that innacurace night vision, sometimes happened after refractive surgeries, because the córnea área that had been reshape was not the enought to cover the diameter of the dilated pupil of individual in a dark place (night, and that could explain the point of light appear as stars and envolved in a pale halo, and the bad contrast of objects too, that appear better when I put a -1,75 glasses (my brother prescrip.)

Well at the moment I think that the 2 possibilities. I honestly want that would be a inicial myopia as Cactus sad, because I working on this fot 6 months now, using minus cls, to induce some amount of myopia.

What you opinion Cactus, Sound, or anybody else, would be a laser problem or a sucessfull case of process of induced myopia?

PS: Soon I will back to a ophtamologist to see if there is any myopia

LEO in PERTH 28 Aug 2014, 04:50


How you going Mike ?

Any chance sending that email ?

My address same as posted on 29 th July.


Danbert 22 Aug 2014, 06:56

*All in all I would suggest...


Danbert 22 Aug 2014, 06:54


As a matter of fact, I tried that once. I think it minorly confounded the examiner as he had to repeat some tests multiple times before my eyes adjusted to the exam conditions. I'm not sure that the end result was affected in any way, and I think the slowness of my response was a direct result of the fact that alcohol is a depressant - my neurons were firing more slowly and things were just taking longer than normal.

It's an interesting scenario to consider though, actually - alcohol should in theory cause the pupils to constrict (the opposite of dilation) which probably isn't going to give you an accurate result - if anything, you'll measure slightly less myopic than you really are. However, during withdrawal the eyes will in fact dilate slightly as the effects of alcohol wear off. All in all I was suggest that whether or not you are under the influence you'll probably get more or less the same result in the end.

choch 22 Aug 2014, 03:05

I know none of you wanted to reply to my first post but I have another question. Regarding alcohol and the relaxation of eyes. Basically my thinking is alcohol helps the eyes relax to their full potential. Assuming you would be very careful and thorough with the comprehensive part of an eye exam (1 or 2), would this be helpful in getting an accurate prescription? Obviously not drunk or anything but with a social amount of drinks, 2-3 I feel like it could potentially be benefitial. Any thoughts, danbert, cactus, soundmanpt?

Danbert 21 Aug 2014, 08:03


From my own experience, I can say that my eyes feel more relaxed when focused relatively close, in spite of obviously having to accommodate more in that situation.

Last time I checked I was only very slightly myopic (-0.25D). However, when sufficiently tired I too find maintaining focus at distance increasingly difficult. Possibly accommodation is less of a problem for me than maintaining fusion at distance. Or perhaps my eyes are accustomed to near work in terms of fusion, yet haven't gone myopic. Just my possibly incorrect theorising.

choch 20 Aug 2014, 12:37

I wasnt sure where to post this but I have a question about my eyes at rest. I've noticed that when I completely relax my eyes (like trying to fall asleep or whatnot) my eyes turn slightly inward and focus really closely. i noticed the close focus one time when I was just messing around and pryed open both my eyes to see what kind of vision they gave like this and what my eyes looked like at complete rest. I can tell you it was not a pretty sight. my eyes in the picture I took looked almost like a literal blind persons eyes would. I've always understood that in order to get a proper glasses prescription, you need to relax your eyes completely. so does this mean im actually really nearsighted with a inward prism and im just unnaturally fixing it somehow? also would this prove that eye exercises do have some benefit in lowering your minus prescription depending on who you are? a hyperopic eye allows for accomodation on weaker prescriptions to where you might not notice you need the correction until way later on in life. so am I running into a similar concept right now with myopia? cactus? soundmanpt?

Cactus Jack 19 Aug 2014, 21:29


I suspect you may have developed some myopia and these are the early signs of it.

I don't know if you are familiar with the iris function and the meaning of the f stops on high end camera lenses, but they perform a similar function as the pupil in your eye. In bright light, your pupils close down to reduce the intensity of the light on your retinas. In low light conditions, your pupils open up (as if your eyes were dilated). There is a phenomenon associated with the iris on a camera lens and your pupils. It is called "Depth of Field" or range of useful focus. When the iris or your pupil is closed down, the range of useful focus is very broad. When the iris or your pupil is opened up, the range of useful focus is very narrow. What that means in practical terms, is that you may have sharp vision in bright light, but in dim light, you are really not seeing very well because your pupils are open and the images on your retinas are slightly out of focus. It is likely that you really need to wear some contracts or glasses for really good night vision.

Out of focus images are very troublesome at night because they cause two other problems. The first problem you described as the star or blurred halo around a point source of light. The other is that many point sources of light at night are very dim, such as stars in the sky, at if they are not properly focused, they can be impossible to see. The explanation is a bit technical so please bear with me.

Light is made up of photons and the intensity of the light is determined by how many photons strike the rods and cones of the retina. The number of photons that arrive at your retina from dim sources at night is very limited. If the image of the light source is small, dim and out of focus, image is spread out over a small area, the number of photons that strike a particular rod or cone may not be enough to cause it to react and send a signal to the brain. Even though there many be several hundred rods and cones being hit by the photons, the intensity may not be enough to trigger a response from any rod or cone. If that happens you may not be able to even tell that the light source is even there.

If the blurry image is properly focused, it may strike fewer rods and cones, but he intensity will be high enough to trigger a nerve imp use to be sent to the visual cortex and you "see" the image.

I don't know how well the above will translate into French or if it makes sense to you. I think you actually need to get some minus glasses or contacts. If you decide to get an eye exam. Let us know, because we need to tell you what kind of exam you need to get and what to say to the ECP.


Soundmanpt 19 Aug 2014, 19:54


I know in the past one side effect of PRK was that often times night vision wasn't as clear and perfect like day was. In many cases patients complained of lights haloing. In quite a few cases low minus glasses was prescribed for night use. But I honestly thought they had solved the problem some time ago. At any rate if you really can see noticeably better with your brothers glasses after dark you should make an eye appointment and bring your brothers glasses along. If your able to prove to your doctor that your able to see the eye chart perfect with your brothers glasses I am reasonably sure he / she would write you a prescription based on your night vision issues. Remember doctors have no way of disproving you have vision problems after dark. Now I can't promise you that they will write you the same prescription as your brother's glasses, but I am quite sure they will write you a prescription for glasses. Doing this is still a much better option than spending so much money to have your vision altered.

I really would like to wear glass with a true reason as Mike

In the night in a reall dark places my vision is not ok, so when I test my brother -1,75 glases the vision become better. And when I see for a point of light the light appear as star! again with the -1,75 stay perfect. This happens after PRK probably

Anybody familiar with this situation?


NJ 18 Aug 2014, 12:46

Nick, I wore soft CLs for GOC for many years, and no optometrist noticed.

Cactus Jack 17 Aug 2014, 20:41


Normally, soft contact lenses do not affect the corneas and there is no evidence of having worn them.


Nick 17 Aug 2014, 17:24

I've been wearing -2.25 contact lenses for around a month now trying to induce myopia. The reason I chose contacts was so I could wear them with friends with no questions asked. I want to have my test tested soon. Does anyone know if an Optometrist will be able to tell that I have been wearing contact lenses? (Obviously I will take them out for the exam)

Mike 16 Aug 2014, 09:39


In my experience you can cheat the auto refractor. I did and I have the slip it prints out to prove it. I was maybe very slightly myopic .25 at most I went to the eye dr. They put me at the auto refractor and I stared at the image with my eyes blurred out and held like that, it came out with minus 4.50 in one eye and 4.75 other side I forget the cyl. numbers.

I know everyone is telling you to not fake or you cant trick the eye dr. I did however fake an eye exam at two different eye drs. As a matter of fact, the first dr. Would not fill the rx I came up with he said it was too high for someone who never wore correction he wanted to knock off a couple diopters. I went to the next dr. They had no problem giving the full rx. Both rx were very similar.

I'm telling you this not discredit the advice you are receiving from the people here who a far more knowledgable than me. I know they are right it makes no sense to fake an exam. I did it due having the feel of truly being myopic and having a dr tell me that im myopic is part of my craving for myopia. I need to feel as much like a natural myope as possible to satisfy my needs.

antonio 16 Aug 2014, 05:29

yes, soundmanpt is right, Lalau,

and outside the house you could even wear a -1 pair for reading far or so you could tell, it happens people need them even after lasik, I´m sure.

Or do you do that already ?

best regards, antonio

Soundmanpt 15 Aug 2014, 21:12


Okay I now understand your situation by still living with your parents. No I don't see any real risk by doing ICL as long as your able to convince a doctor to do that. But won't you still have a problem by suddenly starting to wear glasses again with your parents? I'm sure they are going to insist that you go back to where you had the PRK done. You do understand that as soon as that doctor looks at your eyes he will see the lenses. Your right that it is nearly impossible to trick a doctor or fake an eye exam to get glasses. About the only thing you can do if you want is to complain to your doctor that your having trouble seeing at night to drive. This is the one thing a doctor can't really check and they have to take your word for. Doing this should get you a small prescription of -.50 with an AR coating. I know it isn't much but it's better than nothing and at least you will have glasses to wear. Again though don't try and fake the exam, just complain about seeing after dark. I wish I had a better answer for you as to how or what you could do, but your situation is very unique for you to again wear glasses.

antonio 15 Aug 2014, 17:55

hi Lalau,

wouldn´t it be easy for you to put some about +3 contact lenses in and some -3 glasses on your nose afterwards whenever you want to wear some -3 glasses outside ?

of course the exact strength of the + lenses should be calculated more carefully, but wouldn´t that be easy ?

you could even use your old -3 glasses then.

it´s called GOC.

best regards, antonio

Lalau 15 Aug 2014, 14:42

Thanks Sound, but in my case this would innaceptable because I still living with my family. My father paid my laser in that time, when I was 22, as we know any laser procedire is very expensive. In my family mind I really would like to rum away from glasses, and actually I was. Today, they would Never understand that I want to go back to glasses again, so if they see me usiing it., the first thing that they would ask me is: Are you beçame myopic again?!

And then convice me make an eye exam with my doctor that made my PRK, and this my friend, I wouldn't do, considerando the impossibility of cheating the auto refractor

The best alternativa to me right now is the ICLs, and I want reforce that this would vê a future solution, until there I will be always sharing my thoughts and doubts here.

Sound, do you see any risk in ICLs procedure? My goal is go Back to Rx -3,00 (old prescription before PRK)

Thanks everybody

Soundmanpt 15 Aug 2014, 14:11


As long as your eyes don't have any problem wearing contact lenses in some very decent prescriptions why don't you just stop worrying about working so hard trying to make your eyes myopic? Clearly you main goal is be wearing glasses once again because you now miss them. Why don't you just decide on a nice prescription and order glasses from Zenni and wear them as if you need them? Just because you'll still be able to take your glasses off and see perfect, your the only one that is going to know that you don't your glasses. In other words stop wasting time messing with contacts when its really glasses you want to wear. So just wear them. It would be different if your eyes were refusing to accommodate a prescription but you have been wearing some decent prescriptions already without any problem. The idea of trying to find someone to preform surgery on on your eyes to make you myopic is at best in this case risky.

Lalau 15 Aug 2014, 13:17

Ive been trying induce myopia by use of minus cls for exactly 6 months today, but my view remains perfect. PROBABLY in my case this strategy would not work anymore, because of my age (24) For mame sure I will keep trying for the rest of this year

For those who get sucessfull índuce myopia, how many months take to appear any result? Ive heard something about 1 or 1,5 year. If this is true thats the reason that I haven't saw any result.

Soundmanpt 13 Aug 2014, 15:07


When you get your eye exam ask the doctor when he finishes the exam if he/ she will measure your "P.D." for you? I think in most cases they will do that since they usually don't work for the optical store their working out of. Now the opticians may or may not provide that because the P.D. is a part of ordering glasses and not the eye exam. But still many will do it anyway even though they will know your planning on going on line to get your glasses.

Also "Cactus Jack" didn't give you the entire website to look at for glasses. It is: zennioptical,com

There is no way or reason to try and get a higher prescription when you go in 10 days to get your eye exam. Like "Cactus Jack" said get your actual prescription and then Cactus or myself can make suggestions on what prescription you should order for glasses. Remember Zenni doesn't require a doctor's prescription. So getting you into -1.50 glasses should really be quite easy if that is what you want to wear.

Lalau 13 Aug 2014, 14:38

Míke any news?

If our córnea don't allow laser our gol would be ICLs!

ICLS could be implanted a whole lide right?

Lalau 04 Aug 2014, 21:31

Cactus, any considerations about others refractive cirurgies able to induce myopia?

Cactus Jack 03 Aug 2014, 22:16


Do you have any contact lenses or other glasses with a minus prescription?

I it is very difficult to fake a prescription in an eye exam these days. One thing you can do that is very easy, is get the most accurate proscription you can. In other words, don't cheat. Get your complete prescription, but don't order glasses new glasses yet. Contact us and we will help you interpret your prescription. Then we will tell you how to increase the sphere - never change the cylinder or axis - and how to order inexpensive, high quality, glasses on line with any prescription you want.

Your PD (Pupillary Distance) may not be shown on your prescription, but we can tell you how to measure it yourself. You will need your PD to order glasses.

Many of us have had excellent result from Zenni Optical. If you can, look over the frame styles they offer.

May I ask where you live, your gender, and your occupation? With that information we can tell you a few things you can do or not to do for the exam. 10 days is not much time to have much effect, but lets explore what is possible.


Ilikespex 03 Aug 2014, 19:12

21, currently -0.50 in each eye. I have an eye exam in 10 days. Is there anything I can do to induce my myopia to -1.50 in each eye before this?

Thank you

choch 03 Aug 2014, 14:56

Anybody have any theories on what TDCS through the occipital or temporal lobe would do to the vision? (transcranial direct current stimulation).

Lalau 02 Aug 2014, 13:18

Mike, soon I will create an email to correspond with the eyesceners. Then I"ll pass to you.

Cactus, what others refractives cirurgies do you think make possible to índuce myopia, excluding PRK or Lasik

I've reassina that some laser cirurgy that eliminate presbiopia, works inducing some amount of myopia, to compensate the close view. This technology use a "wave front" laser, with a modern laser equipament form Germany.

Anybody knows more precisely informations about others laser cirurgy that índuce myopia?

Mike 02 Aug 2014, 08:23

Lalau, post your email I will respond.

Lalau 02 Aug 2014, 02:06

Mike, Can I ask you a personal email? If you doný mind, obviously.

Lalau 02 Aug 2014, 01:57


What procedure you have in mind, PRK or Lasik?

Lalau 02 Aug 2014, 01:54

Antônio, thanks for your informations. I found this article:

After read it, I THINK and understand that the limit of changes that a laser can do in a córnea depends of cornea thickness. If a cornea is still thick enought after the laser cirurgy also still remains enought corneal structure to abaulate the corneal surface to give the pre determinded Rx of myopia, I dont´t think there is any problem.

Obviosly we will only do a laser procedure if a COMPETENT doctor says that is totally safe, after a 1a PRK laser cururgy. And that all point: Where could we find a trully competente and secure place, that agree in do such procedure?

Maybe induce a hight level of myopia after a PRK laser is really impossible an dangerous, but a small or a médium Rx I THINK is still possible, obviously, depending of corneal thickness of the paciente.

If you or anybody else have more precisely informations about these question, would be ver useless.

Mike 01 Aug 2014, 08:34


I do not know if you are referring to me regarding your statement but rest assured I would never do the second eye til the first is fully recovered and well

Antonio 30 Jul 2014, 01:35

To Lalau and others. Please be very careful. A laser has already cut into your cornea a lens so you can see fine now. Your cornea isn.t as thick as before now. It has been weakened by laser ablation. You can.t do that cutting procedure often therefore. Furthermore if laser cutting is done badlyyou can, t see clearly any more afterwards and even any glasses wouldn, t help you any more. Glasses can only correct spherical and cylindrical i.e very easy optical faults. If a laser makes a mountainous reason out of your cornea you won.t see anything clearly your whole life again regardless of what glasses you wear. Then you are sort of blinded. Because of that risk in Europe one operates often only one eye at a time, not both. And if the person, s cornea has been damaged one tries to help constructing special contact lens for exactly that broken cornea to make something like a sphere out of the mountains but it costs thousands of euros and people don.t see good with it. Often they never can read a sign ora book again. So please don.t be stupid!!!! Such a situation is awful.

Lalau 29 Jul 2014, 22:29

I"M pretty sure that we will be sucessfull, but I will hold my exam for this cirurgy in the short future. As Im pretty decided to become myopic, there is no doubt or reflexion about regret later. I was myopic and know theory limitations, but the positive side for me is much more bigger. So I want to become again.

Don't worry about the cirurgy, I did PRK and is really OK, nothing radical as seems to be in a 1a view. But as Cactus sad, what laser cirurgy is possíble uns tour case (hight myopia -12 to 15 )? PRK or Lasik?

Mike 29 Jul 2014, 22:00

Not at this point, im not in big hurry I do need to figure out a plan in the next month.

Lalau 29 Jul 2014, 21:23


Any progress in tour research to find a place that can help you in México?

NJ 29 Jul 2014, 10:40

Revolver, while I agree with your general premise that the refractive surgery we're discussing lacks the medical oversight that gender reassignment surgery does, perhaps this is because it is not yet recognized as medically necessary.

The notion that medicine has a fixed and static set of diagnoses is common, but incorrect. We're constantly recognizing new conditions and inventing names for them. Just look at the evolution of the DSM over the decades. And with the advent of rapid genomic testing there are all sorts of new disorders and variants of normal being discovered.

Of course, less common disorders are much less likely to get picked up. It's a safe bet that anyone who really shares our obsession/fetish strongly enough to consider refractive surgery has probably already found their way to this site. So in the entire world there appear to be just a few who are considering surgery as an option. This is not likely to get noticed by the medical community.

I can't speak for others, but I spent 30 years doing GOC with high plus lenses. I know almost all one can possibly know about life with these glasses and so felt very prepared to make the transition. Unfortunately I did not have the benefit of a DSM list of criteria, nor an accepted pre-surgical checklist of psychological testing. Medicine has not gotten to this point and I was unwilling to wait.

In fact, on the list of life-changing surgical procedures one can do, this one is rather minor. Sure, there are inconveniences I have to deal with, and times I can't do certain things because I'm having a bad contact lens day. But overall, my life has not really changed in any meaningfully negative way.

Mike 29 Jul 2014, 10:32

Leo, I will shoot you an email later

LEO in PERTH 29 Jul 2014, 09:54


Do you mind corresponding with me ?

Mike 28 Jul 2014, 22:00

Thanks Greg,

Mine started young maybe 3rd or 4th grade but I didnt realize what it was. I always had a crush on girls with myopia. I could care less about plus girls and thats the same today, plus women are no different than bare eyed women to me. I still remember 2 specific girls from middle school vividly they were both considered kind of nerdy but they were beautiful to me. In my later teens curiosity about what its like to be dependant on minus glasses started I would try on my sisters glasses when no one was around she was moderately myopic then im sure it has gotten worse she only wore contacts. It just started getting more addicting. At that point I was way too embarrassed to consider wearing glasses, even to consider the notion. But time passed and the urge got stronger I became less interested in myopic women and more interested in me needing glasses im still only attracted to myopic women or extremely hot women who are out of my league anyway. My wifes a beautiful woman who wears minus 5 contacts sometimes I get lucky and she will wear her glasses all day but shes still self conscious of herself. Thats a brief story of how my obsession started.

I will drop you a line via email thanks again its nice to talk to people who think alike.

GreginColo 28 Jul 2014, 21:11

Mike, I think many of us have experienced issues where we have ingrained desires that cannot be met though "normal" channels and finally come to the realization that what is normal for others may not be for oneself. I have had a myopic fascination since 2nd grade, I can remember exactly when it started. I thought by having lasik surgery to correct my own myopia, that would also resolve the fascination issue so I could spend that time and energy on more productive tasks. So while my procedure to have surgery to improve my vision might be considered normal, my underlying reason for wanting it was not. In my case the vision improvement was gained, the the myopic fascination remains as strong as ever, hence the time I still spend on this site and related correspondence.

So while I can't advise you what to do, I do understand why you feel that need and how powerful it can be. It sounds like you have already persued a number of avenues for resolving this need/desire in more traditional ways. Sometimes that works, sometimes not, but I am glad you have explored those, and come to the conclusion that it is not a passing fancy, or something you can ignore as part of who you are.

It seems like your desired correction range is pretty reasonable, sufficient myopia to be dependent on full-time and significant correction, but at the same time the range you consider can allow you wear glasses that are quite thick looking or ones that are fairly normal looking, due to today's different lens technologies.

I have had off-line correspondence with the UK guy that I believe he and his very significant increase in his myopia to the upper extreme are quite legit. What I don't know is exactly what procedure he had done in Mexico to accomplish this. Unfortunately I haven't heard from him in a couple of months so don't know his current status, but it does raise concern within me.

This desire of your for increased myopia, is that something fairly recent or is that something of a much longer term?

You also mentioned a fairly short term window, is that coming up very soon? Sorry if you have already answered some of these, its been somewhat hard to follow your posts, and the related responses, on two different threads.

If you want to communicate in more detail you can email me at and I will respond with my regular email. Regards, Greg.

Mike 28 Jul 2014, 20:31


My comparison was to be taken very lightly, I am well aware of the significant differences between these procedures. My apologies for lack the of ability to thoroughly articulate my desires and needs. But simply put I'm sure years back at some point gender reassignment procedures were unheard of and it took many people to lobby for its approval and clinical trials and all the other fda bs that treatments go through for years before getting approval as a clinically recognized medical procedure. You said its far more invasive, but who would want to destroy perfectly good vision with minimally invasive eye surgery. Its a psychological situation in my opinion and at least there's a solution for people who can be proven to be in need of that type of procedure. I have been to the experts they couldnt do anything for me so the mechanics wont work on me.

Revolver 28 Jul 2014, 20:03

While this discourse is interesting, in no way can gender reassignment be compared to elective (and some would say, regressive)refractive surgery. The difference is that the gender procedure is not entered into that lightly, before anyone can be approved there has to be another medical procedure, that being extreme psychological testing. It has been recognized as a real medical condition and if diagnosed as such will be approved by the shrinks. The surgeons and therapist are only mechanics, if the shrinks approve their ethical concerns are fulfilled and the surgery will be performed. The common thread in this discourse is "I have no idea why I want it, I just want it, and will go to any means to get it". Big difference.

Mike 28 Jul 2014, 16:16

Point taken NJ,

Thank you

NJ 28 Jul 2014, 16:05

Mike, no judgement here. I've been (am) there. I've often thought of gender reassignment as a good comparison, which is a much more risky and invasive procedure.

Just want people to go into this eyes open so to speak.

Mike 28 Jul 2014, 15:54


Thank you for you're concern and voice of reason I have been round and round about this and see no other option and I am ready to assume all risks.

At this point I have to do this just like other people, to cure what ever deep desire they have may it be vision impairments, having gender reassignments I have even heard of people having limbs removed far be it for me to judge what drives people.

PLEASE do not assume im crazy I am thinking far more clearly than I have in a long time by just coming to terms with myself

I greatly appreciate you're concern

Thank you again

Mike 28 Jul 2014, 15:42

Cactus Jack,

I just responded to you're other post please excuse my absence I have been busy all day I will shoot you an email later this evening feel free to respond at you're own convenience

Thanks again


Cactus Jack 28 Jul 2014, 15:11


I think permanent significant myopia is possible, if that is what you want, with some surgery. I don't think Lasik or PRK is the answer. Both involve sculpting the cornea and I doubt seriously if your corneas are thick enough to make it possible to shape your cornea so that it has significantly more PLUS power than it does.

I suggest that it is very important for you to understand a bit about optics and how your eyes work. Simply stated, to create enough myopia so you will need glasses in the -12 to -15 range, you will likely need to increase the PLUS power of your eye's lens system by about +10 to +12 diopters. The calculations are similar to GOC, because of vertex distance issues and actual lens location within the eye. The laws of optical physics will be the limiting factor. But understanding what is involved will help you decide what you want to do.

I have asked a few questions on Refractive Surgery thread.


NJ 28 Jul 2014, 14:58

One more thought. Over the years I've been all over the map with GOC, from -40D to +28D. In my experience, high myopia is more easily corrected than high hyperopia. As a -30D myope I could function pretty well. I still occasionally do GOC after my surgeries, and I can say with +30D I am extremely visually impaired because I have so little visual fields.

Not trying to encouraging anyone, just relating my experiences

NJ 28 Jul 2014, 14:53

Greg and Mike, I have a couple of thoughts.

First off, I think it will be very hard to get that level of myopia via Lasik. Lasik is good at reducing myopia but not so great at making it worse. That's why people with more than a small amount of hyperopia are not good candidates for this procedure. Again, I'm no expert, but I think an ICL is the best option. An IOL is problematic above a certain level, where you need to have piggy back lenses. I know this from reading the literature on cataract surgery for people who are already hyperopic. The reports here of someone who got a -50D script through surgery are, if I may be so bold to say, pretty unbelievable. It's so far beyond what any existing technology can do. (This is a site where people routinely engage in fantasy, after all.)

Second, please think long and hard about having any procedure done that gives you terrible vision. I know many of us think we really want this, but once you have to face life day to day with super strong glasses and little vision without them, your life does really change and not all for the better. Basically you go from good vision being the default and having to work to get bad vision, to bad vision being the default and having to work really hard to see. Although I am doing reasonably well, there are certain things I cannot do without contracts and I can't always wear my contacts. Just please think about this before you do anything irreversible.

Mike 28 Jul 2014, 14:49

Leo, its good to know im not the only one hiding this from a significant other.

For me I have to have something done if I dont my quality of life will continue to suffer I can not believe something like this can have such a profound effect on my life and I have a family to support. I find myself daydreaming and fantasizing about having true high myopia and it literally makes me less productive in my day to day obligations. I have been to shrinks, psychic mediums, and hypnotherapists to try and deal with this without going in for a surgical procedure to alter my vision. I did use aliases when seeing the mentioned professionals so my secret is still safe.

However I need something done to ultimately satisfy my needs.


LEO in PERTH 28 Jul 2014, 11:06


I too would LOVE to be myopic.

I read your write up, its as if you knew me.I wear GOC,

-8 most times, as my "" normal "glasses ,and -17 at home.

My wife knows its a free lens from Zenni's , and understands why its thick ,but doesn't know about GOC.

The problem with GOC is the times I have to rest my eyes ,and wear my real glasses. that's why Iám thinking about wearing Prism glasses.

Mike 28 Jul 2014, 03:55

Thank you Lalau,

I bet youre right about about finding someone in south america. It should be possible.

I have to admit I would be a bit nervous travelling in mexico for this procedure. I have been to the tourist destination s down there like cancun and Puerto Vallarta however the thought of going into tijuana or mexico city makes me nervous but im sure its safe I just lack knowledge about these places. Given the opportunity I would possibly hire a medical escort to go with me.

lastly nothing would stop me from making the trip. It sounds like the guy from the uk went home safe.

Mike 28 Jul 2014, 03:41


Thank you for the info I believe the guy you're referring to was the one case that sounded promising as in a surgeon and clinic with an open mind to treating a patient in a way that will make their quality of life better even if the treatment goes against all normal treatments. The way I see it there are dr's out there willing to surgically change a humans gender, in my opinion the people having procedures like that are no different than someone like the guy from the UK with the -50 myopia or me just wanting marginally high myopia. I am speaking for myself only but I need this to make me feel complete for me this is about quality of life. I didnt choose to have this need for myopia I have tried to hide it avoid and forget about it, basically tried everything under the sun to get rid of this need for myopia.

Regarding youre other questions

The main things I want to be completely dependant on glasses to the point of not seeing anything and I mean anything. light and dark pure blur is all I want to see when I take off the glasses no shapes or anything what so ever

I would want to wear glasses 99% of the time and if feasable have the option of contacts only for a specific event were I risked breaking my glasses.

I do want to have thick lenses I just do not want to look akward to the point where it may make me stand out as unique. I know no one at this site would ever judge someone on their glasses how ever there unfortunately is still alot people who may not look at me the same as they would someone with unaided vision. I cant risk my lively hood on this and I have to deal with clients on a daily basis and they are used to me wearing glasses. I wear cr39 lenses now so if I came in one day wearing -15 in high index material im sure not many will notice.

The last reason is hard to put into words. It involves the dependancy, and the blur, the look of thick minus glasses to me thick polished lenses look better than diamonds all of that together is nirvana for me.

I pretty sure I would be happy around minus 15 with as long as it provides the blur and the lense thickness and cut in I want to see when I look in the mirror. I have no desire to be myopic to the 20 30 or even 50 range that is amazing they were able to achieve that for the guy from the UK I happy he got what he wanted.i wouldnt be upset if I somehow I ended up around minus 20 I just may wear part of the script in contacts occasionally and as long as I could see good enough to drive.

My wife knows nothing about my myopia obsession I am the only person on the planet who knows I managed to carry this with me privately all this time. I can thank her for me getting glasses initally her being a minus 5 herself and being a self proclaimed expert on everything (sarcasm) she felt I needed an eye exam and when I came out with a minus 4.75 sph and 1.25 cyl script she was running around telling everyone how she new I needed glasses and she was right just not exactly for the same reason. I dont know how she would handle the truth if I came clean I dont think it would ruin our relationship but it would be very akward for me and I dont need that because my myopia and glasses bring me so much joy I wouldnt want to feel ashamed about it she would never completely understand shes not in my body feeling this.

I did mention I have a window of opportunity when she will be gone for a couple weeks

I would prefer to remain anonymous in the open board but will give you an email address shortly

Thanks again Mike

GreginColo 27 Jul 2014, 23:23

Hi Mike; I don't have any specific recommendations at this time but perhaps some general words of encouragement. I had lasik surgery about 10 years ago to improve my myopia from a -6 range. I regret having the surgery as I miss being myopic so can kind of relate to your feelings of wanting to be more so. I keep hoping there will be some natural regression but that hasn't happened.

There was a guy from the UK who went to Mexico and had surgery to achieve his goal of being extremely myopic and I think he ended up around -50, certainly beyond anything I have ever seen or known of. He and I had kept in touch for a bit but lost touch as he and his partner traveled thru South America before returning to the UK, so I sure hope they are okay. If I hear from him again, I will ask him for more specifics of his surgery if he is willing to share.

It sounds like you have thought this thru well and have this as an important personal goal. If you don't mind me asking what are some of your reason(s) for wanting to increase your myopia; is to wear thicker lenses glasses, to increase your dependence on correction, or other reasons.

I am guessing you are not wanting to do this just to wear contacts most of the time. I also wonder if you get to the desired -12 to -15 range if you think you would then like to increase that even more.

I presume you have discussed this with your wife and she is at least accepting of this desire of yours. I am sure that would be a question an opthomologist might have.

If I talk with the guy from the UK and get more specific info do you want it posted here or sent to a personal email.

Good luck and best wishes, Greg

lalau 27 Jul 2014, 23:02

This noticie really give more holpe Mike. I will start my reasearch to find someone soon. I believe in my country is definetely more easy to find someone, obviously with the right amount of cash ($$$). Btw Im in South America.

Mike, do you any amount of miopia?

Mike 27 Jul 2014, 21:41


There was someone here a few years ago that was able to find a surgeon to do laser work on him to give him myopia he never mentioned where or who. If I remember correctly he was lasered to the -6 range I dont recall seeing any posts from him recently

Thanks Soundmanpt, you gave me great ideas, to save some money. I"ll think in bus 2 glasses to intercalate with cls.

Mike, keep us imformed about your effort to find a ophtamologist, obsvioly it's wall be really hard to find anyone in US imaediatilly. But Im pretty sure you can find ir you really want. I will pronably go for the saem way ( laser cirurgy, if my cornea allow)

Anybody here knows anybody that find a doctor that as able to do a laser for induce myopia? Please if anybody knows or have a tip, help us!

Mike 27 Jul 2014, 17:29

Sorry about the double post

Mike 27 Jul 2014, 17:28

Hello all,

(I will also be posting this in the induced myopia thread as well, there seems to be more activity on this topic over there lately however I feel this would be the correct thread)

For the longest time I deeply desire to be significantly myopic 12 to 15d range. I am willing to take whatever means necessary to make this happen.

I wish to have the procedure done via laser surgery so there would be no chance of reversal as in the case implants however my main questions is:

Would any for of laser procedures be possible if I found a surgeon willing to perform what I want (I am in the united states and willing to travel into mexico where I understand others have been successful in finding dr"s willing to implant lens for the same reason) (btw I would be willing to pay for assistance from other members of this site whom have already done the legwork of finding a willing surgeon)

A bit of background info:

33 yrs male

Been wearing -6d glasses since 2009

I was able to obtain the presription legitimate ly from a lenscrafter optomitrist and have not been back since I was able to convince the auto refractor I was 4.50 and final refraction of 4.75 and 1.25 cyl this script was good but I also had my frames made with 6.00 even in both eyes which worked a bit better. I did this by relaxing my eyes to blur out my vision when I first started wearing this script I could not read very well or blur my vision however after a year I could read well and blur my vision again....continued

Mike 27 Jul 2014, 17:27

Continued from previous.

So I can now blur my vision to the level I could before the first exam so I may try my luck again to see if I can get a bit higher (I understand that its not an accurate refraction however it is part of my thrill).

Back to the main question can I achieve what I want with any laser procedures I have no idea of my corneal thickness I dont have dry eyes and my internal pressure is normal But could this physically be done in a perfect world with out limitations? Or do I need to drop it as a potential possibility and consider an implant.

Lastly I have a window of opportunity in the next few months my wife will be gone for 2 weeks when I could dissappear to have this done. Money is no issue and obviously I would only have one eye done first and if alls well do the second eye. This is the risk im willing to take to ultimately make my quality of life better so please no negative comments they are my eyes I was born with this desire and this is ultimately what I need to do

Thank you in advance

Okay so if your able to wear -4.75 contacts without much problem except for late in the evening. So why not start wearing glasses with say -1.50 lenses along with your -4.75 contacts. Do that instead of getting stronger contacts. This way you will be re introducing yourself as a glasses wearer again. It is not uncommon for someone's eyes to slowly change back after having surgery. So you would only have to tell people that you started noticing that distance was blurry and you found out you again need glasses.

If the combination of -6.25 is too strong then simply order some contacts a little bit weaker. That way you keep the same glasses. This way every so often you can stay with the same contacts and just increase the power of your glasses from time to time.

lalau 25 Jul 2014, 17:24

Hi buddy, I'm using right now a -4,75 cls (2 months with this power) without much problem,I only have some dificult to read in the very end of the night. Honestly I'm thinking in increasing the poder to -6,00 soon. Cactus sad that some of tour clients get able to induce some amount of myopia, increasing the Rx power slowly and achieve the power of -20.00 for read! Those clients had the same age that I have now, 20 something. That the reason that keep me trying with this strategy.

I can buy weak and strong glass/cls anytime I want because all my family are myopic, so it. just take theory prescription and go to shopping.

About GOC or use glasses beeing emetrope would be really weird, because everybody know that I did laser cirurgy, and I wouldn't fale to everybody.

Really good to know I'm not the 1a person in would that regret of PRK and the try to to back to glass! ;D

Soundmanpt 25 Jul 2014, 13:32


Your not the first person to get lasik and then decide that they really missed wearing glasses. Because your 24 chances are your just past the age where you could induce myopia, but then again maybe not? If you haven't tried it might be worth it to give it a try. But really even if your not able to induce any myopia anymore your eyes should still be quite able to wear glasses with some prescription to them. Can you get to -3.00? I doubt it, but you should be able to get to -1.50 or maybe even more. I would suggest that you go on line and order glasses in -1.00 to test the water. Your eyes should have no trouble tolerating that much.

This would be far cheaper than any surgeries your talking about.

lalau 25 Jul 2014, 13:21

NJ, I find this

Maybe a "re treatment" with a laser cirurgy still be possible, as you sad, the all question is the córneal thickness. Considerang that my doctor sad that I had a very thick cornea before PRK and my miopia was low to médium (-2.75/-3.25), maybe my córnea still alow a second laser intervetion, I will study the possibility for me in the next years if the cls strategy failed

lalau 25 Jul 2014, 12:35

Hhahahah, well GOC just don't seem to be a good choice, like everybody else I would like to use the glass witth a "true" reason. About the doctor Im pretty secure I could find anybody with a sérios research, the question is to offer the right amount of money, maybe.

For me the best solution is the refractive cirurgy to índuce miopia, but in my case it can be not possiby anymore, because the double-PRK could be risky.

NJ the ICLs are visible to naked eyes for the others? In a hight light ambient

NJ 25 Jul 2014, 10:04

Male, 57. nothing special. don't get excited.

 25 Jul 2014, 09:35

NJ are you male or female?

NJ 25 Jul 2014, 09:33

Lalau, you can certainly get that prescription using an ICL, though I'm not sure an ophthalmologist would recommend it. You can much more easily do this using simple contact lenses and glasses over them. It is my understanding that ICLs are more commonly used for high prescriptions, where it is not possible to correct with other surgeries like Lasik. Same for IOL placement for non-cataract uses.

lalau 24 Jul 2014, 11:06

NJ, Thanks for your explanation.

I did the PRK (+/- 1,5 years ago) to correct my vision, but I regreted to do the cirurgy, because I percepeted that I look much beter with glasses and not without it.. To try to go Back to glasses, in the last 5 months Im trying to induce any amount of myopia, using minús Cls all day along, increasing the Rx power of Cls progressivily, as Cactus adivised me in the beginning of my effort. But the chances are against me, in reason of my age (24). I don't if helps very much to índuce myopia, bus Im doing close work with my vision in the most part of my day (studies)

Actually, Im considering the ICLs opertation only if the next years if I had no sucess in the Minus Cls estrategy, lets se watt happened. My gol is to back to my last prescription, that as around -3.00. This Rx can be achivied without problem with the ICLs?

PS: I know It sound crazy, to do a refractive cirurgy and the try to go Back to glass, but I Never liked to use glass when I needed it, and always used Cls. I realize that I look beter with glass, just when I have done the PRK, haha

NJ 23 Jul 2014, 17:57

Lalau, I am curious why you had PRK done before. What it to improve your vision? If so, why do you now want to become more myopic?

An ICL is placed either in front of or behind the iris, not directly by the cornea. My uneducated guess is you could have one implanted. Just a guess.

I think the bigger problem will be finding a surgeon who will do a procedure to make your vision worse without some obvious benefit to you. Our community understands, but most eye care professionals don't.

And though an ICL can be removed, please think very hard about changing your vision so drastically. Even if you think you want such bad vision and will enjoy the glasses, you'll find that it changes your life in ways you may not like.

lalau 23 Jul 2014, 15:03

Thanks Cactus and NJ. After a refractive cirurgy is well known that the cornea stay less thicker (sorry the wrong term). I honestly don't know the level that my córnea had been modified, so NJ or Cactus, do you would know awnser me if after a refractive cirurgy it still possible to do a procedure that envolve the cornea? Like ICL

NJ 23 Jul 2014, 10:51

lalau, I think it is usually is possible to place an ICL after other refractive surgeries. There are some requirements for ICLs that concern corneal thickness and structures around the iris and anterior chamber, so no guarantees. Also keep in mind that surgeries can get more complicated the more you have, due to scarring. However, I'm not an ophthalmologist and am no expert in these matters.

Cactus Jack 23 Jul 2014, 10:21


Should be possible. Insertion of the ICL involves a very small incision at the side of the cornea. To increase myopia a PLUS lens would be required.


lalau 23 Jul 2014, 10:15

NJ or. anybody else, know ir is it. possible to do a ICL procedure after a PRK laser in the eyes?

Jake 23 Jul 2014, 02:56


I hope you still remember me! I owe you an apology for my month-long absence; I'm finally back home now for some time, so I won't be as neglectful in replying!

Your explanation of latent hyperopia/pseudo myopia is very illuminating - I think I'm beginning to understand, although I also understand that there is a lot more to it. As for the thought experiment (will my ECP become suspicious at a sudden big increase?), this is actually something I've given some thought to in the past. First, I think most opticians would find it difficult to imagine that someone actually wants his myopia to deteriorate. I also think that if my real myopia is somewhat stabilizing (although I still harbor the hope that it actually isn't), I don't believe that my increases will be bigger than what I've had before (-2.00, for instance). If the increase is somewhere around -1 or -1.25, which would be ideal, I think my optician would really have no choice but to write me a new prescription.

I've also had another question that I've kept to myself for some time: are there any things I could do on a daily basis(apart from GOC or overcorrection treatment) that have a chance of making an appreciable impact on my myopia? I'm thinking of something like sitting close to the computer or reading in the dark - I know this is quite primitive, but I wonder if there's any point in doing that. At present, I'm trying to wear my -3.25 glasses (which are now quite small for my face, but still wearable) over my -5.75 contacts - this still gives me decent sight, and hopefully it's a step in the right direction as far as inducing latent hyperopia is concerned.

Once again, sorry for the lack of reply - I'm still here! :)

P.S. I'm also contemplating posting some of my school memories elsewhere on eyescene - as I mentioned, I graduated recently, and more than half of my class was myopic. I have some really nice myopia-related memories, and I'm wondering if you think its worth sharing with eyesceners.


NJ 22 Jul 2014, 15:34

LXW, I don't know if it is possible to wear contact lenses with ICLs.

LXW 22 Jul 2014, 14:41

Ok, i will think about it, thanks. But please let me know, is it possible to wear contacts with ICL or only glasses?

NJ 22 Jul 2014, 13:06

LXW, I can't think of any good story for why you would want to such high myopia, other than saying you do a lot of close work. In my case, the natural magnification of my glasses can be used to help with moderate low vision. There's even some references in the older literature for doing GOC using minus CLs and plus glasses to magnify the image and help with acuity. Unfortunately minus glasses reduce the image size so this won't work.

LXW 22 Jul 2014, 12:11

NJ, thanks for your infos, i am happy to see that somebody would help me! Yes, i think ICL is the right solution for me. GOC is nice, but i want it the other way... Yes, you are right, i need a very good story for the optometrist here in germany. Any ideas are welcome :-)

NJ 22 Jul 2014, 09:30

LXW, I think the best way to get -10D of myopia, if you don't want to keep doing GOC, is with an implantable contact lens (ICL). You can easily get this level of myopia and you can have the ICLs removed if you change your mind. I think to achieve even that level of myopia with an IOL might be a challenge. The only downside to either is that the optometrist will notice the artificial lenses and might ask why you have such bad myopia with these lenses.

NJ 22 Jul 2014, 09:24

JB, I was able to get the amount of hyperopia I wanted without the IOL, in the +18D range. I could have gotten an IOL make that even bigger but in my experience once you get above +20D the choice of available lenses goes was down and the lack of peripheral vision gets pretty severe and limiting. I was actually surprised that I needed even a +18 correction. I had a couple of diopters of hyperopia before the surgery, so I was thinking I'd need about +15D I was surprised.

JB 21 Jul 2014, 21:30

NJ Afetr read better tour text I undsrtanf your pont.

But why did you didn't decide for IOL?

JN 21 Jul 2014, 18:41

NJ definettly I'm not familiar with those procedure, and that explain why Im not understand your point

Im 24 and treying to índuce myopia for 5 months right now, with minus contact lens. I increasing the minúscula RX slowly. But considering that my chances are pretty small to gain any myopia. im considering that in the future to to any cirúrgical procedure to implant any internal cls

Excluding the refratáveis laser to reshape córnea, watt the others procederes that you could advise?


NJ 21 Jul 2014, 17:59

JB, certainly when you go to an optometrist she'll see the ICL or IOL. It might be a bit awkward to explain why you have high myopia plus an ICL or IOL. I don't have that problem. I just say they were unable to place the IOL because of internal structures.

JB 21 Jul 2014, 17:44

The implant of internal cls or contact lens extration, it is visible for other people when they te looking directly for us? I believe that with the right amount of money any clínic would do any procedure right?

NJ 21 Jul 2014, 12:06

LXW, I'm probably the person you refer to about the clear lens extraction, which I had done here:

Obviously such a procedure left me quite farsighted, which is what I wanted. Myopia is a little more problematic to induce, but it could be done I think with the appropriate IOL placed in the eye. I don't know if this place would do it, but they didn't ask a lot of questions when I went there. Perhaps you'll get lucky. I did have a cover story that was plausible, that I have low vision and need the magnification to see, and that I'd been wearing minus CLs under strong plus glasses for years but can't tolerate the CLs anymore, which is true. Anyway, they had no problem doing the procedure.

Ed 21 Jul 2014, 10:51

Leo. You have similar aspirations to me. I really wanted to be short sighted from around the age of 9 ish. When I was 10 I had my eyes tested at school, and I was desperately trying to work out what to say I could see to get a prescription. I gave up as I was not sure. today I know, but I am too old for my eyes to change. The women in my life have all been myopic ranging from -2 to -9.75. The higher the script the better the sexual side of the relationship. I would like the courage to do GOC at -12.

LEO in PERTH 21 Jul 2014, 06:54

I always wanted to wear glasses from the age of 12yrs!When I discovered the EYESCENE, I thought my prayers were answered, doing GOC. I soon learnt that GOC is temporary ,not full time.

Iám 62 soon,the "want" is stronger ,IOL or lense implants are almost impossible ,unless one has extra cash.

I 've been considering wearing prism glasses ,because I don't really have much choice.

I would love to wear -12 glasses for the rest of my life.

JB 20 Jul 2014, 19:09

Well, the other to aquire a ´real``myopia, excluding the refractive cirurgy, is the use of minus internal contact lens. I do~´t think so this technique is very agressive for the eyes. Does anyone know that anybody in the fórum tried use glasses by this way?

Roy 20 Jul 2014, 15:48


I can only tell you what happened to me. I would not recommend it to anyone else. You only get one pair of eyes and I would not suggest anything that could damage them.

There are a few other points I could mention regarding my experience.

I actually had some double-vision around the age of 15 or 16 and was prescribed 2 base up & 3 base down to cure this. It worked perfectly and this vertical prism is still part of my prescription.

When I first wore glasses with 4 base out I actually found the vision with these glasses less strained than the same prescription but without the base out prism so I think this correction may have been needed anyway.

I have had some eye tests where the prism correction prescribed has been higher than I was wearing.

All these points make me think that my need for the base out prism may have been real and not induced.

LXW 20 Jul 2014, 11:49

Yes, i have read all the postings and found it, thanks. But i think he had done a Clear-Lens-Extraction. I only want to be nearsighted by about 10 Diopters or so. A CLE ist to much for me i think... Would be happy if anybody knows a way or a methode for it. Thanks

Soundmanpt 19 Jul 2014, 19:41

If you look back in this thread someone a while ago claimed they found such a doctor to do what your wanting. I am not sure where this doctor was located, but if your that determined I am sure you would make the trip.

 19 Jul 2014, 16:00


yes, i know - i am to old to induce myopia :-( My next idea is to search somebody (doc / clinic) who will "modificate" my eyes so that i have to wear glasses / contacts with about -10dpt´s. But it´s hard to find... Or i will do the same like Roy with his prism glasses.


Nick 19 Jul 2014, 14:04

Does anyone know if it's possible to induce myopia through GOC?

JB 18 Jul 2014, 18:11

Does anyone heard any case of people that decides to induce miopia by laser cirurgiy?

Soundmanpt 17 Jul 2014, 14:58


I'm afraid your dreams of becoming myopic to the point of needing -10.00 glasses is not going to happen. The fact that your 39 makes changing your actual vision nearly impossible. Inducing myopia can work well for someone 18, 19 or 20 but after that it becomes more and more difficult.

If your eyes are able to tolerate -1.00 and even -2.00 glasses now you probably can't go much more than that. Going any higher is up to you but because your job involves a good deal of close work your eyes may not be able to see clearly enough to do your work.

I don't wish to get involved with your desire to include prisms into your glasses. I will only say that Zenni does do prisms and I believe the cost is about $9.00 additional.

LXW 17 Jul 2014, 12:29


Thanks for your message and sorry for my fail. I am male and 39 years old, i am selfemployed and have a lot to do with computers. I do service (repair, setup and so on) for computer machines and i do CAD drawings. Very much time on the PC monitor.


thanks for your explanation! So you think the right way is to start wearing prism glasses all over the day? And increase the prisms from time to time.


Roy 17 Jul 2014, 10:44


I am in my mid sixties and have been wearing glasses with prism correction full time since my mid thirties. I started with 4 base-out right eye only and increased it steadily to reach 10 base out in both eyes (i.e. 20 shared)by the time I was about 50. I can't remember how long it was before I started getting double vision without glasses but probably around 2 years after starting to wear the prism correction. Over the next few years the double vision increased to approximately match the prism prescription of the glasses I wear.

Cactus Jack 16 Jul 2014, 18:40


Between Soundmanpt and myself, I think we can guide you. One important thing, that I don't think you have mentioned, is your age. Also, your occupation would be helpful.


LXW 16 Jul 2014, 15:52


Thanks for your info!

And sorry for my english (i am from germany), i can´t really explain what i want...

My eyes are working perfect and i need no glasses. But i often wear glasses with less diopters (like -1 or -2) because i like it very much. I also do GOC with plus contacts and minus glasses.

My dream is to become nearsighted in reality, but there is no doctor who wants to operate my eyes because they are perfect :-( I like to be dependent on glasses like -10 or maybe more.

Alternatively i want to wear high prism glasses all the time. Without prism glasses i would see everything double, but how to train my eyes??

Thanks very much,


Soundmanpt 16 Jul 2014, 09:49

LXW (Alex)

You don't need the help of a doctor to push your eyes if that is what you want to do. There are many on line retailers that you can order glasses in whatever prescription you choose to wear that don't require a doctor's prescription slip. Even better the glasses are not expensive at all.

I highly recommend that you look at Zenni ( for your glasses.

You didn't say if you currently wear glasses or if your starting off with perfect vision? If your vision is perfect or near perfect you should probably start off with a prescription that your eyes can adjust to. Something like -1.00 is good for starters and is still enough to make a difference in your vision and allow you to get used to wearing glasses full time.

Once your eeys have adjusted to those glasses then of course you may want to increase the power of the glasses to make yourself more dependent on your glasses.

Good luck!

LXW 15 Jul 2014, 15:52

Hi Roy,

i am also interested to get prism glasses forever.

How long and often did you "train" your eyes with prism glasses?

The other side is to get myopic, but i don´t know a way for this :-( I don´t know any doctor who will push my own eyes to maybe -10 or more...

Thanks for all,


Dimitry 15 Jul 2014, 15:38

That's what I meant. Roy is right. hbk, if you want to change up your optical experience, why don't you order some bifocals or progressives? That way, you'll be able to read better with the stronger minus lenses.

Roy 15 Jul 2014, 11:02


I tried increasing my myopia in my thirties but had no success. It stayed at around -3.5 right eye and -6 left eye. I also tried a 4 base out prism in my right lens to increase the outer edge thickness to match the thickness of the stronger left lens. Over a period of time wearing this prism did cause double vision and I started increasing it. I now wear, and need, 10 base-out in each eye. I am happy with this but be warned if you take this path. Double vision cannot be corrected with contact lenses or lasik so you would have to wear glasses all the time.

hbk 15 Jul 2014, 08:15

If I relax my eyes while looking at something close I see double but that is it.

nnn 15 Jul 2014, 01:09


What do you mean damagin eyes? His vision with glasses is going to be worst than someones with high myopia?

I was going to try prism press on prism once but I haven't yet.

I am courios about the results.

Cactus jack 14 Jul 2014, 21:22


5 BO in each eye causes about the same amount of convergence as reading at about 1 meter. Actual turn-in is about 0.57 angular degrees per prism diopter. 10 BO in each eye is about like reading at 1/2 meter. Can you become used to wearing prism and get to where you prefer it, Yes. However, like Inducing Myopia, it helps if your eyes want to turn inward anyway. Because your eyes are converged like you are reading, you need to adjust your PD inward about 0.27 mm per diopter for the same reason near PDs are less than distance PDs.

Have you had any problems with double vision?


hbk 14 Jul 2014, 17:17

Dmitry- yes that happens to be it.

Now for others who have done the same thing I am curious what all you have experienced. Thanks

Dmitry 14 Jul 2014, 16:56


If you wear prism when you don't need it, you will be doing a lot more than inducing myopia. You will be damaging your eye muscles.

Come on!! Is that what you really want?

hbk 14 Jul 2014, 10:12

I have decided that I want to order glass with prism after not having a lot of luck inducing myopia. Last official RX was L +.75 R +.25. I wear full time L -4.00 R-4.50, was wearing -3.25 and -3.75 for about 9 years before that and this new rx for the last year. Currently 30 years old now. I can still read fine with my right eye and have to try a little more trouble with my left when using one eye at time and experimenting. I was thinking of starting out with 5 BO each eye. I think from past post I have read I saw CJ post something about not starting with more than that. Debating if I am going to up the rx a little thinking probably so.

I am curious those of you that have ordered glasses with prism what did you start with and what what point did you notice them?

Cactus Jack 13 Jul 2014, 00:36


I am not sure if you are aware, but Progressive Myopia can be an extremely dangerous condition if the eyeball grows too long. As the eyeball grows beyond a certain amount, retinal detachment become a very great risk. If that occurs, blindness can result unless the retina can be quickly re-attached. It seems to be pretty rare, but severe Progressive Myopia can affect even pre-teens. I know of a boy in a rural village in Northeast Brazil, who requires glasses in the -30 range. He will be 14 soon, but had retinal detachment that left him with little vision about 2 years ago. Fortunately, it was discovered early and the boy was flown to Sao Paulo. where a laser was used to reattach his retinas.

Think of the benefit to mankind if Hypnosis could STOP Progressive Myopia. It is certainly worth investigating.


Cactus Jack 13 Jul 2014, 00:17


With exceptions, about the only myopia that can be induced after the age of about 20 - 25 is Pseudo Myopia.

The brain is an incredibly powerful organ, but I am having difficulty understanding how Hypnosis can directly affect biochemical processes in the Pancreas and the production of Insulin by the Islets of Langerhans in people with Type 1 diabetes. Admittedly, Type 1 diabetes is believed to be an autoimmune disease where the immune system attacks and destroys the Islets, a discovery that this process can be stopped or reversed by Hypnosis warrants a formal double blind study,

Also, the revelation that Hypnosis can cause production of the, as yet unidentified, eyeball growth hormone is also very significant deserving of a carefully controlled study that includes ultrasound measurement of eyeball length. There is some evidence that Nanothalmia and Extreme Hyperopia is caused by the eyeball failing to grow properly as the head grows. Hypnosis could be the cure fot those conditions. If Hypnosis can cause the eyeball to grow, perhaps it could also STOP eyeball growth in people with Progressive Myopia.

You did not mention your age or where you live, but I would suggest that you organize a research program to study, develop, and prove that Hypnosis can do these things in at least some of the people. I am certain that there are members of this forum who would be willing to help fund this research if it offered positive results.

I can think of a way that you might be able to use Hypnosis to induce Pseudo Myopia, would you be willing to volunteer to be a test subject? It would involve an eye exam before the Hypnosis and perhaps several exams afterward to gauge the permanence?


Daland 12 Jul 2014, 18:15

I belive, that Hypnosis CAN make the eye grow.

As I was able to make the "Blood-Sugar-Level" sink at an Diabetes Type I, without any Insulin-Production.

Doing Hypnosis, everything is possible!

I was already able, to stop accomodation in my eyes.

I needed reading glasses!!!

Normally I have "Eagle Vision"!

This is the way to induce Pseudo Myopia.

Cactus Jack 11 Jul 2014, 16:47


I have often wondered myself if hypnosis could be helpful in Inducing Myopia. I don't think it would help for Axial myopia because that seems to be a biochemical process closely related to genetic factors. However, it might be possible to use it to help with Pseudo Myopia.

I seem to recall that it is possible to use Hypnosis to "freeze" certain muscles that are under conscious control. Some of the involuntary interconnections in the brain between the focus control system and the eye positioning system might bet in the way and cause undesired consequences, such as strabismus, but it would be an interesting experiment. Hopefully, Deland will find someone to help him and he can report the results.


lalau 11 Jul 2014, 16:30

Cactus, actually I could consider me on of your clientes, your already gave great advices via email. Im posting here to try help anyone in a similar situatuon

Danland is there any cientific prove that hyponoeses really workks to make an eye grow more?!

Daland 04 Jul 2014, 08:28

This is, what I thought already, because it is 2 years ago an nobody speaks about it today...

As I am doing Hypnosis (as a Show), I was able to learn, what out body in combination with our Brain can do.

I belive, that it is possible to make the eye grow, by giving this advice in deep trance/hypnosis.

I am unable to do this myself, because you can only archieve a medium trance level yourself.

Maybe I can find a "colleague" who might do this.

Cactus Jack 04 Jul 2014, 04:16


I am not certain, but I don't recall any posts that said this "technique" was successful. It may have been a hoax or a scam.

There have been some successes using traditional techniques, but they depend on your Age, Genetic Makeup and your diligence to have any hope of success. If you want to explore Inducing Myopia, we might be able to help, but there are no guarantees.


Daland 04 Jul 2014, 02:26

Hello Everybody!

About 2 years ago, someone posted, he had invented a turning wheel, which may produce myopia by watching it.

Two questions:

1) Is this true? Can you induce myopia with this?

2) Where can you download the video from the wheel. The original link is no more existent.

Thank you

So now it all began to make sense. She finally admitted to me that she really missed wearing glasses and didn't find wearing "plano" glasses appealing. So she had been considering what kind of prescription her eyes could handle because she knew it might be tricky because her vision was so good. And when I came in with those antique glasses and she tried them on she was thrilled that even though they were still a little strong for her eyes she could see pretty well with them and she knew that doctors really only can go by what a patient says when it claims to driving at night. She said her store doctor wasn't very happy to see her wearing them full time but there was nothing he could do. Also because of the warranty she had with "TLC" she had to go to them every year to get her eyes checked to keep the warranty in place. She insisted she didn't want her eyes to get anywhere near as bad as they were before lasik. At her re exam her eyes had changed slightly, but she didn't really need glasses. When she went for her exam at TLC her eyes were 20/30. Not long after that she left town with her bf and was gone for about 2 years. I heard from someone that she had returned to town and was again managing an optical shop. I went to see her and she was happy to see me as well. We went to a nearby coffee shop so we could talk. Of course she was wearing glasses still but different ones than she had of course. She must have known I was curious because she said that I would be happy to know that eyes had not gotten any worse and that her glasses are still just -.50 which she is fine with and that she had intention of her eyes getting any worse.

Soundmanpt 03 Jul 2014, 12:07


She even took the glasses over to read what the prescription was, When she sat back down she again out the glasses on and was testing her eyes even more before returning them to me. It was about a month before I went to visit with her again. When i saw her she was wearing glasses. I was a bit surprised because even though she had several pairs of "plano" glasses in her drawer she never ever wore them. I told her I liked her glasses and said "plano"? She said no that they had a prescription for night driving. I asked her what the prescription was and she said -.50 and again insisting she only needs them for driving at night. She told me she had gotten them a few days before so didn't ask anymore questions thinking maybe she was just wanting to get used to them. But 2 weeks later when I went to visit her she was wearing the glasses still. Now I couldn't keep from commenting. I teased her by asking her if she was getting ready to drive somewhere since she had her night glasses on? She smiled and just siad that she was wearing them because it would look good if since she worked in optical for her to be wearing glasses and insisted she only wears them at work. Another month or so went by and she was showing me pictures of her going back home for a visit. But I couldn't help but notice that in every picture she was wearing her glasses. I would sometimes bring in some olf the sample glasses i had from Zenni to show her and get her opinion on. One of those glasses she really liked. i told her I would be happy to order her a pair for her. She thanked me but refused. Anyway since it was very close to Christmas and also her birthday had just pasted I decided it would be nice to get her those glasses as a gift since they were only about $18.00. But I remembered her saying that she had an astigmatism of -.25 in one eye. So I happened to know her asst very well. So I called the asst on a night when I knew my friend wasn't working. I know it against all the rules for someone to give out some else's prescription, but I asked anyway and told her what I was wanting it for. She thought that was really nice and pulled out her bosses file. When she pulled it she found something she didn't even know. The doctor notes indicated that her eyes were still 20/10 and he didn't recommend glasses to her, he wrote her a prescription "for driving at night only" and she was to be re examined in 3 months. So she said maybe i should hold off until after the 3 month were up to see what the results might be then. At this time it was already very close to her being examined again anyway.


Soundmanpt 03 Jul 2014, 11:34

Cactus jack

It's interesting because as much as so some claim they can't wait to get lasik because they have been wearing glasses for so long, that not that long after having the surgery and coming away with perfect vision and in some cases even better than perfect vision they soon make the decision to go back to wearing glasses. I actually know 3 different ones that did exactly that. All 3 were in optics and as far as I know they still are. The first one was a young lady that I was friends with and she her prescription was in the -5.50 area with some astigmatism. Because she had abused contacts when she was younger she could no longer wear contacts. Someone from "TLC" came to where she was working and gave her a card that entitled her to have lasik for $1,000.00. She got it done was thrilled with the results. her vision was 20/10 and was holding at around that 2 years later. I would visit her every 2 weeks or so in the evening after the doctors hours. On one visit I brought with me an antique pair of glasses from about 1920 or so. When I showed her the glasses she examined them and even put them on. The prescription of the glasses was just a -.50. The vision center was in the back of a rather big dept store. Her view from the optical center was looking out into the store. She claimed she could read signs in the store better with those glasses on which I found interesting for someone with better than average vision.


Cactus Jack 03 Jul 2014, 00:05


That is very interesting. You are my second recent "client" who has had PRK and is now regretting it and is trying to induce some myopia. You are very near the same age and had about the same prescription before PRK and wearing - contacts for the same reason.


lalau 02 Jul 2014, 23:22

Cactus I cannot wear glass until induce a mtopia again, because would be strange my Family see me with glass and view still being fine. So I will have to try a gol with cls

I was around -3,00 before PRK, and I made the cirurgy around 1 year and a half ago. I jsut hope that with my age (24) still be possible to induce some amount of myopia, pseudo or axial there us really no diference for me. I jsut would like to go back to glass wth a trully reason for that.

Cactus Jack 02 Jul 2014, 09:22


I have seen the article, but have not read it completely. It appears to be a paper written to fulfill an academic need rather than to provide useful information to an audience who has limited knowledge of optics and optical physics.

Are you familiar with the expression "Too many cooks spoil the broth"?

Have you had PRK? When? What was your prescription before the surgery?

I am curious why you can't wear glasses?


lalau 01 Jul 2014, 23:09

Cactus have you ever read this article?

lalau 01 Jul 2014, 23:06

Yhanks, the last post was really mine. I tied to find some information about induzing myopia, but everything I found is in this fórum.I suppose this is a tabu area, it is so hard to find enought information to learn the basics of inducing myopia and the eyes Works in that cases. That the reascon that I so dumb in this field Cactus.

I will keep trying with this stratefy all over of this year. I will make a eye exam soon, probably when I complete 5 months with minus lens. I will post the result here, obviouslt U cannot use glasses after my PRK, so my gol will continue with cls.

Cactus Jack 01 Jul 2014, 21:08


I assume the last post was from you.

If you can recover that quickly from wearing the -4.75 contacts, it is very unlikely that you have developed any myopia of any type.

You could have some astigmatism or even a little hyperopia, but they would probably not have been caused by wearing the CLs.

Astigmatism is generally caused by uneven curvature of the front surface of the cornea. Hyperopia is caused by the eyeball not growing enough. Younger people can easily correct hyperopia if it is not too great by using their ciliary muscles and crystalline lens in exactly the same way as a person who is wearing stronger minus contacts or glasses. It just reduces the total accommodation range that is available to focus close for reading or other tasks.

I strongly urge you to read some books on vision and how the eyes work to help you understand how all this works.


 01 Jul 2014, 20:21

Cactus, I was thinking in increasing the Rx for -5,75, this power looks good for a emetrope (probbaly my case)to you?.

I really don´t know what is my actual prescrip. because I don´t go to a ophtalmologist since I start the effort of induce myopia. My view apparently is still fine with no cls, for distant and close distances.

When I take it off my cls, it´s just take about 2 seconds or even less to my view recover the natural focus 100%.

Soon I intend to make a eye exam in a ophtomologist, to verify if I had any increase in myopia.

Cactus, can I develop any astigmatismo or a hypermetropia using minus in the eyes? I never thought about that!

lalau 01 Jul 2014, 20:10

Antônio, I feel perfectly fine, it´s just take some days to your eyes get adapted to the minus power. But I alreay used cls for 8 years, I had myopia but I made PRK lase, but now I just percepted that I look mych better using glasses, haha.

I see everything perfect after 2 or 3 seconds when I put the cls in my eyes.

But my estrategy to get a fine adaptation is incresing the Rx slowly, I based that in the Cactus advices. First I used a -1.75 for one month, then a -2,75 cls for another month months and now I using a -4,75 cls for 2 months and a half. Everything indicates that very soon, maybe after 3 months, I will have to increase the minus power of cls, to make my ciliary muscles work harded to increse the possibility of the beginning of a pseudo or even a axial myopia. Let´s se.

PS: When I get back to cls after the PRK laser, I was emetrope, my vision was totally fine, right now, I cannot say 100% that I develop any amount of myopia, because I didn´t back to eyes exams, but I can say that I can see everything perfect without minus lens, so porbably no sucess yet.

Cactus Jack 01 Jul 2014, 18:47


Wearing your -4.75 CLs for close work is probably slightly less important than wearing them all the time, but constant wear is important, when ever you are awake. Wearing contacts when you are asleep is of no benefit and may not be safe. It depends on the contacts.

If the -4.75 contacts have become comfortable when focusing close, you might consider increasing them to -5.00 or -5.25. May I ask your actual prescription. You may have mentioned it, but I have forgotten.

Antonio's question is a good one. How is your distant vision after you take out the -4.75 contacts after having worn them all day. If it is a bit blurry, how long does it take for your distance vision to clear up after you take out your contacts?

antonio 01 Jul 2014, 18:25


how do you feel if you put these lenses out of your eyes ?

what can you see then ? Does your vision get back to clear view at all ?

best regards


lalau 01 Jul 2014, 17:13

I understand Cactus, is increadible how medicine is still misterious in a lot of things

I would like to know f close work, using minus lens, during some hours everyday could be considered a primordial estrtategy to induce myopia (axial or pseudo)? Or this is a secundar thing, what really matter is the personal body reaction of each person?

I asking because I doing close work with minus lens for 4 months now, increasing the minus Rx of the cls constantily, but right now (4 months with this strategy) my is still fine.

PS:Right now Im with -4,75 cls, and my eyes are almost 100% adapt to that power, for close and distant view

Cactus Jack 30 Jun 2014, 20:23


We don't know enough about the actual genetic mechanism to know exactly where genetics no longer plays a role in Myopia, however it is doubtful that genetics plays much of a role in Pseudo Myopia.

Pseudo Myopia can easily continue after 40 if you continue to wear glasses with minus overcorrection for distance and bifocals or trifocals to help you focus to read. It is helpful if you start wearing over correction and get used to it before presbyopia really sets in. By wearing over correction, your crystalline lenses will be very reluctant and very slow to revert back to their relaxed state after your crystalline lenses become very stiff.


lalau 30 Jun 2014, 19:48

Thanks, so if I understood your point, genetics factor dont´t have any influence in Pseudo Myopia induced aritificially, like a Axial Myopia? The only fator that matter in this cases is the personal reaction of cristaline and ciliary muscles in each person?

So it is impossible to continue with a pseudo myopia after 40´s because of the presbyopia right?

Cactus Jack 30 Jun 2014, 18:04


It depends on several factors. The younger you are, the more likely that you might induce some Axial or True Myopia. For Pseudo or False Myopia, the situation is reversed where being older is better because an important factor is the stiffness of the crystalline lens (presbyopia) and how slowly the ciliary muscle relaxes. If you have little or no presbyopia, you crystalline lenses are not very stiff and will usually relax very quickly so there will be no apparent Pseudo Myopia.

One 30 year old "client" was able to achieve enough Pseudo Myopia to be able to fail an army vision exam after being given a very strong dilating agent, but it was a very touchy situation. Inducing Myopia is ALWAYS a very "iffy" situation and there are no guarantees.


lalau 30 Jun 2014, 17:39

Hi Cactus, thanks for your explanation, it is Always very helpfull.

Let me ask you one more thing. Everybody develops false myopia when they trying induce myopia with minus lens? If not, the majority or minority could develop a false myopia?

Cactus Jack 30 Jun 2014, 00:33


Il existe deux types de myopie, axial ou vraie myopie et pseudo ou faux myopie. Ils ont deux causes différentes, mais qui ont le même effet et la même correction. Vrai myopie est provoquée par la croissance du globe oculaire trop longue et est considéré comme permanent. Le globe oculaire pousse naturellement depuis l'enfance jusqu'à environ 20 ans. L'âge réel où la croissance du globe oculaire s'arrête varie selon l'individu. Si le globe oculaire devient trop longue, True myopie est le résultat. Pseudo ou Faux myopie est causée par les muscles ciliaires et le cristallin de détente pas entièrement. La plupart myopie qui se développe plus tard dans la vie est vraiment fausse myopie et beaucoup myopie induite chez les personnes âgées de 20 est vraiment fausse myopie. Il n'a vraiment pas d'importance ce genre de myopie que vous avez, vous avez besoin - des lentilles pour corriger.

Il est possible de développer encore myopie après PRK ou Lasik, plusieurs années après l'intervention chirurgicale. Il est probable qu'ils ont effectivement développé Faux myopie.

Il est très rare pour une personne de développer plus vrai myopie après leurs 20 ans à une exception près. Souvent, les femmes qui ont développé vraie myopie importante quand ils sont jeunes deviennent souvent plus myope si elles tombent enceintes. Apparemment, la grossesse provoque la production de l'hormone qui contrôle la croissance du globe oculaire. Il existe certaines preuves que cette hormone existe, mais à ma connaissance, personne n'a été en mesure de l'isoler. On croit que l'hormone est produite par la rétine, mais personne n'est vraiment sûr que ce soit.

Cactus Jack 30 Jun 2014, 00:32


There are two kinds of myopia, Axial or True Myopia and Pseudo or False Myopia. They have two different causes, but have the same effect and the same correction. True myopia is caused by the eyeball growing too long and is considered permanent. The eyeball grows naturally from childhood until around age 20. The actual age where eyeball growth stops varies with the individual. If the eyeball grows too long, True Myopia is the result. Pseudo or False Myopia is caused by the ciliary muscles and crystalline lenses not relaxing fully. Most myopia that develops later in life is really False Myopia and much Induced Myopia in people older than 20 is really False Myopia. It really does not matter what kind of myopia you have, you need - lenses to correct it.

It is possible to develop Myopia again after PRK or Lasik, several years after the surgical procedure. It is likely that they have actually developed False Myopia.

It is very unusual for a person to develop more True Myopia after their 20s with ONE EXCEPTION. Often, women who have developed significant True Myopia when they are younger will often become more myopic if they get pregnant. Apparently, pregnancy will cause the production of the hormone that controls eyeball growth. There is some evidence that such a hormone exists, but to my knowledge, no one has been able to isolate it. It is believed that the hormone is produced by the retina, but no one is really sure about that either.


lalau 29 Jun 2014, 22:46

Yhanks Cactus and Soundmapt for the explanations. I made some confusion around what I ve been reading of you both, maybe beacuse I am not a english native.

I´ve heard some cases of persons that made PRK or Laskik cirurgy to correct myopia with their 20´s, and they develop a recident amount of myopia again when they were around 30´s. Is this possible?

This cases don´t make sense with the cientific explanation that a eye´s person cannot grow afetr their 20´s right?

Cactus Jack 29 Jun 2014, 17:14


Just to confirm, It is VERY rare for Soundmanpt and I to disagree on any vision topic. In fact, I can't remember anytime we did. I tend to be a little bit more aggressive, but not by very much.

After your genetics say "no more Axial Myopia or eyeball growth", all that is left is the possibility of Inducing Pseudo Myopia. That is a slow process and you need to wear as much over correction as you an comfortably handle every waking hour. You need to understand that Pseudo Myopia IS NOT PERMANENT and that you will revert to your natural prescription or very close to it when you stop The speed of the reversion depends on your ciliary muscles relaxation and your progress toward presbyopia.


lalau 28 Jun 2014, 23:01

Thanks my friend. I understand your point, I really made some confusion beetwen your explanations. Like Cactus Jack you are Always very prestative.

Have a good Sunday.


Soundmanpt 28 Jun 2014, 20:21


Cactus Jack and myself are not giving different advice at all, in fact we are very similar in our opinions. I am saying that it can be too taxing on the eyes if you over correct by going so strong that the glasses, or contacts are uncomfortable to your eyes. And I know Cactus Jack and myself totally agree about the importance of constant wear. Meaning that as soon as you open your eyes in the morning you put your glasses or contacts on right away. Then you don't remove them until your closing your eyes for bed that night.

Once you feel your eyes are ready for more increase of course you should do that as well.

Age does seem to be a factor and it is hard to say at what age is where you reach the point where your eyes simply can't be changed anymore. But it has been determined that be under 20 is very helpful in inducing myopia.

lalau 28 Jun 2014, 15:57

I heard 2 versions about the funcionality of Rx power in inuce myopia. Soundmanpt theory say that is not the power that helps to induce, but the constant use to force ciliary muscles as much as possible, to start the progress of myopia, is the conitions permit that.

The other is form Cactus Jack, he told me, that is interesting to force the eye as much as possible, is a person is in the limit age to try induce myopia.

I really don´t what is more valid of the 2 alternatives, but I will keep increasing the Rx of my cls after some period of time, even I alreadye been using a hight Rx (-4,75)presbiope like me.

What is opinion about that Soundmanpt? Thanks

HighMyopic 28 Jun 2014, 12:00

Will wearing my -29 diopter biconcave myodiscs for 2 or 3 hours in the car induce more myopia for me? Or should I wear my weaker -22 diopter myodiscs for 3 hours?

Soundmanpt 28 Jun 2014, 11:19

I am sure that there was at least a link or two posted here in this thread. So if you have the time and go back about 2 years, just to be sure you go back far enough since I don't recall exactly when that first came about, you should be able to find it.

But I don't recall if anyone ever claimed that the rotating disk did in fact create some "induced myopia" or not.

lalau 28 Jun 2014, 10:39

Sorry Alex, but for privacity I prefer not to say my country. Anything that you would like to know about buy cls or other information?

I don´t about rotation disks. That thing could really work for induce myopia?

 28 Jun 2014, 07:33

Hey, I'm a long-time reader, first-time poster around here, but I just wanted to ask, does anyone around here have access to that rotating disc video that was mentioned some time ago and is supposed to help induce myopia? I'd really like to try it out.

I'm a 23 year old with a very low minus prescription, and I'd love to be able to increase it.

Thanks, Dean.

Hi Antônio,

I am trying induce with -4,75 lens, I´m have a perfect view right now, but I´m trying induce just for 4 months. I have no problem with blurry vision even to read. But I´m 24 years, so it is not a garantee. My genetics helps me, because everybody in my Family are myopic.

Thanks everyboy for the cares and necessity of take it off lens everyday. I will take more care about that.

antonio 26 Jun 2014, 13:31


what do you wear now as correction in front of your eyes ?

best regards, antonio

Aubrac 26 Jun 2014, 06:25

Sam12744 is quite right you must never wear contacts all day unless they are extended wear lenses designed for this.

The blood vessels start growing towards the iris and at first are too small to be visible other than by ophthalmic examination.

Once the blood vessels have started growing they will never go away and the result can be some loss of vision. I know because this happened to a friend who wore her contacts 24/7 and had no discomfort but at her next eye test was told she should no longer wear contacts.

sam12744 25 Jun 2014, 09:13


If you were wearing the right type of contact lenses for extended wear, then of course you didn't suffer any detrimental effect. If you wear lenses that are intended to be removed overnight,and do not do so, then you are asking for trouble. If the lenses do not allow oxygen through them, you will see tiny red blood vessels growing towards the iris, as the body tries to supply oxygen where it is needed. This is not a good thing.

HighMyopic 24 Jun 2014, 23:09


I wear -5.50 and -4.50 glasses and would love to wear some myodiscs in my Rx. I want to get my eyes used to wearing stronger glasses like -7 or -8 diopters. I have been for the meanwhile, wearing a 2 dollar thrift store pair of glasses that seem to have a stronger pair of lenses to try to get my eyes more myopic. I am 22 years old. I have always loved thick eyeglasses, wearing very thick glasses and currently collect them.

You can email me at

Lalau 24 Jun 2014, 22:56


I used cls for 8 years without any atention of take it off of my eyes all days. Sometimes only one time per week. I suppose that I have some good luck. Do you would know if is there any possibility of the eye get larger, with the wrong size of lens for the type of eye? With the long term and constant use.

 24 Jun 2014, 22:53

Hi Highly, how long are you trying to induce? Have any increase during this effort? What is your age? Tkss

HighMyopic 24 Jun 2014, 22:25

I am not sure. I should have a -29 diopter pair of biconcave myodisc glasses that are coming in the mail for me to wear to try to get my eyes more myopic. I love to wear very strong glasses. My Rx is currently -5.50 and -4.50. I want to get my left eye to a -7 or greater and my right eye to a -6 or greater. I hope that these -29 glasses will help get my eyes to that Rx.

 24 Jun 2014, 20:07

Thanks, does anybody knows if is it possible to have any myopia increase when the eyes get completely grow?I´m 24 years, and trying to induce myopia for 4 months. But eyes still 50-50. I´m using -4,75 lens

sam12744 24 Jun 2014, 09:40

Anonymous poster,

Yes; blindness. The contacts you have been wearing must be extended wear ( breathable ) ones, intended to be worn for a month. While that type is safe if you follow the instructions, even they will clog up over time and reduce the amount of oxygen getting to the eye. At the very least you should take them out after a month and give your eyes a rest before replacing them with new ones. You might get away with soaking them in cleaning solution to extend their useful life, but ultimately the oxygen supply will diminish, risking your eyesight and I cannot recommend that course of action.

 21 Jun 2014, 16:12

Is there any radical consequence of eyes hipoxy? I used to use cls for 3 monthas without take them off! I dont if my eyes suffered in any way for that.

 21 Jun 2014, 16:09

Thank you Sam, but I never find soft cls that aren´t one sized. I use JJ.

sam12744 20 Jun 2014, 07:22

In my experiance, they can still pinch if too small, and a good fit is essential for optimum oxygen supply. If too big, they will just float about, go out of position and come out altogether.

Lalau 20 Jun 2014, 01:34

I Thiyght this necessity of base curve was inly for the rigid cls. The soft one need this too?

sam12744 18 Jun 2014, 06:48


You should get a proper measurement for the base curve before buying contact lenses. If you don't know your base curve, I strongly suggest you go to an eyecare professional and get it measured. This is best done in these circumstances, by telling them you want coloured cls for whatever excuse you care to dream up. They will test your suitability for wearing cls and teach you how to handle them, put them in and out etc. and prescribe the right diameter and base curve for coloured cls with plano RX.

Thus, you will know exactly what to order, when you go online, leaving the diameter and base curve exactly as the ecp suggested and adding the RX to your requirements.

It is dangerous to wear cls which are of the wrong base curve, especially if it is too small for you. Too large may be less dangerous, but they won't sit right and will probably flip out at the most inopportune moment.

HighMyopic 17 Jun 2014, 23:05

Will the soft -20 diopter contacts still fit to my eye when I buy them? Should I get the larger Base-curve or the smaller Base-curve?

 17 Jun 2014, 22:57



HighMyopic 17 Jun 2014, 21:14

Can you buy soft rx contacts online from without getting your eyes measured first? I would like to get some soft monthly -20 diopter contacts to use if I can buy some very strong lentictular glasses first.

Cactus Jack 16 Jun 2014, 11:01


The reason I asked the last 3 questions is to get a better idea of your present level of knowledge. It is actually quite good, but maybe I can enhance your understanding of the optical principles involved. The fundamental mathematics of optics were discovered and codified by Sir Isaac Newton, of gravity fame, around 300 years ago. He defined and named the units of measure of optical lens power and prism power, the diopter and the prism diopter. He also described the difference in the optical characteristics of + lenses and - lenses.

Paraphrasing a bit, a diopter (+1) is that amount of lens focusing power that will concentrate (focus) parallel rays of light from a distant object (the sun for instance) to a point at a distance of 1 meter. A prism diopter is that amount of prism that will deflect a ray of light 1 cm at a distance of 1 meter. Minus lenses are a bit harder to understand because they diverge light rather than concentrate it and their focal point is imaginary and for mathematical purposes located in front of the lens. Fortunately, for understanding how vision works in nature, there are NO minus lenses involved. More about that later.

Newton also codified the most fundamental law of optics about the relationship between lens power and focal distance: Lens Power = 1 meter / Focal Distance or its rearrangement: Focal Distance = 1 meter / Lens Power (i.e., If you know one value, you can easily calculate the other). Also, 1 meter = 100 cm = 1000 mm.

The "normal" (emmetropic) human eye is a complex structure approximately 25 mm in diameter. The eye has a lens system that consists of 4 PLUS lenses. Three of the lenses are fixed power or semi-sided power and one of the lenses is variable focus. They are from front to back, the Cornea (F), the Aqueous Humor (SF), the Crystalline Lens (VF), and the Vitreous Humor. The total power of all the lenses is about +58 diopters. The lens system is inset in the orb of the eye so that the effective distance from the back of the Crystalline Lens to the Retina is about 17 mm.

Hyperopia and Myopia are both caused by a mismatch between the total power of the eye's lens system and the length of the eyeball. If the eyeball is too short, hyperopia results because distant images focus behind the retina. If the eyeball is too long, myopia results because distant images focus in front of the retina.

Whew! Now to answer my questions.

1. The two types of myopia are: Axial or true Myopia and Pseudo or false Myopia. Axial Myopia (considered permanent) is caused by the eyeball growing too long. Pseudo Myopia (temporary) is caused by the Crystalline Lens failing to fully relax. Both can be present in the same eye and their effects are identical, are additive, and have the same correction, a MINUS lens.

2. Latent Hyperopia and Pseudo Myopia are the SAME phenomenon. Which name is used depends on the underlying condition, Axial Hyperopia or Myopia (i.e., the length of the eyeball). The Variable Focus system in the eye consists of two structures. The Ciliary Muscles and the Crystalline Lens. For distance vision they are or should be fully relaxed. Even fully relaxed for distance, the Crystalline Lens still has significant + power, about +15. To focus close, the Ciliary Muscle squeezes the Crystalline Lens, increasing its power. The amount of the increase depend on the distance to the close object. The actual amount needed is calculated used Newton's formula above.

Under the "right" conditions the Ciliary Muscles and Crystalline Lenses can be VERY slow to relax after adding extra PLUS for a long time. When that happens, Pseudo Myopia or Latent Hyperopia is the result. Any wheels turning?

3. Yes, you are correct. Dilation does two things. It paralyzes the muscles that control the Iris causing it to open fully to allow the examiner to check the retina and it paralyzes the Ciliary Muscles so you cannot squeeze your Crystalline Lenses and alter their focus. The most accurate distance refraction occurs with the Crystalline Lenses fully relaxed and ideally, that occurs with dilation. However, most modern dilating agents are designed to have very short active life so the patient recovers as quickly as possible. If the Pseudo Myopia or Latent Hyperopia is well developed, it may take quite a long time for the ciliary muscles to relax and short term dilation will not affect it very much.

Thought Experiment Questions: What do you think your regular ECPs reaction will be if you turn up with a "sudden" increase in your prescription after it had apparently stabilized? How would you deal with that? How could you mitigate that?


Jake 16 Jun 2014, 04:43

Hi Cactus,

Writing has indeed been one of my passions since I got a notebook and pen for my sixth birthday, so I'll continually be able to compensate for my ignorance in optometry with decent writing :)

To answer the further questions:

1. I looked up pseudo/false myopia after I saw a few references to it on eyescene. From what I understand, it is either myopia caused by a separate condition (like diabetes) or some kind of defect in the crystalline lens. This is merely what I read on the internet, so I'm sure that there is much more to it.

2. I had not heard of latent hyperopia before you mentioned it, but I looked it up and read about the basics - that there's a certain amount of hyperopia that might be undetectable with a regular refraction.

3. I believe that I have a dilated eye exam as part of my regular annual eye exam - my eyes are dilated and their health is checked toward the exam (I think that this is what you are referring to, but I'm not sure).

As for the credit card/gift card, I think that's doable. I'm out of town for a month, but when I get back home for some time (this will be toward the end of summer), we can discuss the logistics further.


Cactus Jack 15 Jun 2014, 10:25


Thanks. You are most fortunate to have wide ranging interests and love of learning, You also seem to have exceptional ability to express yourself in writing.

I wish my English writing skills were as precise as yours seem to be. When I was in school, I really did not care much for English composition. I hated trying to write about things that did not interest me and particularly did not like writing about things that did interest me - to be read by people who vaguely understood what I was talking about. I now understand that my dislike of English composition assignments was because I just had nothing to say on the subject.

These days, I do quite a bit of writing on technical and business subjects. I find it a stimulating challenge to be able to convey complex information in easily understood and easily assimilated form, to an interested target audience.

I would like to offer a couple of things to consider regarding ordering glasses or contacts, confidentially. Consider a pre-paid credit card or well known brand of gift card. They are available in many places such as Wal-Mart, Walgreens, or CVS. For receiving items, consider a Post Office Box or Private Mail Box that may be available in some speciality shipping stores.

In the Inducing Myopia department. I am concerned about he fact that you had no increase in you prescription between this prescription and your last one. It is possible that your myopia has stabilized. That means that it is unlikely that you will be able to increase your Axial or True Myopia. However, Pseudo or False Myopia is still possible. Both can exist simultaneously and often do.

More questions,

1. Do you understand the difference between the two types of Myopia, their causes, and the similarity of their results?

2. Are you familiar with Latent Hyperopia and its similarity to Pseudo Myopia?

3. Have you ever had a dilated eye exam? When?


Jake 15 Jun 2014, 05:20

Hi Cactus,

First, to answer the questions about myself (I'd be happy to use email by the way - for now, I'm not revealing anything I wouldn't want to share with other eyesceners, but if you prefer email, please let me know and we can switch): Jake is indeed a pseudonym, which has nothing to do with my real name (except for the gender). I know that there have been at least a few fraudulent/false accounts on eyescene (i.e. people who fake their prescriptions, age, etc.); while I might be vague at times, I assure you that I am not one of them :)

8. I went to a competitive private high school, but I can't see that I particularly focused on math/science (more about this below). I took Calculus AB in 12th grade, and Chemistry, Physics, and Astronomy. Of course, I've also read quite a bit about optometry on my own, so my knowledge is still at a minimum, I think that I'm reasonably well-versed in the basics.

9. I do indeed plan to continue my education. I am taking a gap year next year to pursue a certain interest, but I will be attending college the year after that.

10. I can't say for sure what I would like to major/minor in, but throughout high school I've been quite interested in the humanities, especially European history (but English as well - as you can see, I have pretty wide-ranging interests :), and foreign languages as well (I am fluent in three). The only connection to my love of optometry is that many of my school friends who enjoy history/english are the high myopes of the class, and I love references to myopia/"myopic moments" in literature and film (I might share some of those on eyescene when I have the time, since I think there are many people haven't noted).

11. To be totally honest, this might indeed present a problem. I have a fair amount of independence and a good relationship with my parents, but they are understandably involved in my medical expenses, and I'm not sure how I would be able to sneak in an order of contact lenses that are the wrong prescription and from a foreign location; I could try, but I'm not sure I want to risk it - my parents are not aware of my fetish, by the way.

I'm not sure if someone can go around this - perhaps if I can worsen my vision -.5 diopters or so, I could schedule another eye exam and fake a greater increase. Also, I should make clear that I don't want to go beyond a point where my vision is correctable to 20/20; I certainly want to be able to drive and see well with correction (so, as I said, something like -11.50 would be ideal). Furthermore, I completely understand if, with my limitations, its impossible to induce any significant myopia - regardless of the result, I really appreciate your help. Of course, this will not have any real impact on my life one way or another. With that said, I will have a fair amount of time next year, so I could, for instance, wear old glasses over contacts for a fair period of time most days (I don't know how long one should do this every day for results, since I actually want to be able to see as well :). But I was also wondering if there are alternatives to the GOC/overcorrection.

Despite my lack of specialization in science, I love learning and reading, so I'd certainly be ready to tackle challenging concepts.

In any case, I want to keep my posts to a reasonable length - once again, please don't hesitate to ask for clarification on any of the points above.


Cactus Jack 13 Jun 2014, 10:56


Here is something to think about. You could try wearing some -1.00 contacts under your glasses or just some -6.75 contacts in the same brand with the same base curve and diameter. If you can deal comfortably with that power, you can then increase it as you wish. You can order contacts from a place in Vancouver, Canada without a prescription.


Cactus Jack 13 Jun 2014, 10:46


I understand, whenever it is convent.

If you wish to contact me privately use


Jake 13 Jun 2014, 08:44


I greatly appreciate your willingness to help me! I'm currently traveling, so I might not have steady Internet/a lot of time for a day or two - but I'll get back to you as soon I can :)

Cactus Jack 11 Jun 2014, 03:48


Excellent information. I think that is enough to get started.

First of all, I understand your desire to stay anonymous. You might want to consider using a pseudonym. Obviously, my name is not Cactus Jack. Some of our long time members know my name and where I live, Houston, TX. If Jake is in any way related to your real name, I urge you to adopt a pseudonym. You are among friends here and most of us understand your interest in wearing stronger or stronger appearing glasses.

A little about me. I have a reputation on ES of being a pretty good explainer about optics and vision. However, I am NOT an Eye Care Professional (ECP) and I never allow anyone to think that I am. My background is Electronics and Computers. I am 76 and have 4 years of college on a 5 year program for an EE degree. Over the years, I have had many vision problem and I was not satisfied with some of the answers I was getting from ECPs. Some answers did not square with the Optical Physics I had studied or even with common sense. My fundamental nature is that of a problem solver and I started researching and learning as much as I could about Optics, Vision, and using Optics to correct Vision problems.

I have had a number of “clients” here on ES that I have helped as a “Coach” over many years. I have been able to help some people Induce Myopia, but sometimes it is just not possible. Two of my “clients” were extremely motivated to become significantly more myopic. They wanted to be disqualified from mandatory military service in a country that is noted for the brutality of some branches of their military. With a lot of work and effort one was able to increase is “myopia” from around -4.00 to wearing -20.00 glasses full time and still had enough accommodation to be able to read with them. Most of it was Pseudo Myopia, but enough Axial Myopia developed to allow him to squeak by and he flunked the physical.

I will warn you that I tend to be a bit long winded because am used to teaching high tech subjects, in an industrial environment, to motivated students. My goal is to help you UNDERSTAND the principles, not just learn to follow a recipe in a Cook Book. Now to your answers.

1. 18 and a half may be somewhat problematic as evidenced by your answers to question 6. I is very likely that your myopia is genetic and it is very likely to be mostly Axial or True Myopia. You may have a little Pseudo or False Myopia, but probably not much. I’ll explain the difference later, but mention that they can add together, have an additive effect and affect your total sphere correction.

2. There are 3 main elements in a complete prescription. The first number is your Sphere correction, the second number is you Cylinder correction, and the third number is the Axis (orientation) of your cylinder correction. These are followed by Prism and Add if required. Cylinder and Axis are specified ONLY it you have some astigmatism. You are very fortunate that you do not have any astigmatism and that simplifies your objective. At this point, we are only concerned with your glasses prescription which is the same or very close to the prescription your ECP read from the Phoroptor or Trial Lenses. Contact lens prescriptions are derived by a math procedure using the Vertex Distance of the Phorptor or your glasses. Vertex Distance is the distance from the front surface of you corneas to the back surface of the lenses of your glasses or the first lens in the Phroptor. Vertex Distance calculations are based on the optics formulas developed by Sir Iassc Newton, of gravity fame, back around 1700. We may discuss them later.

3. I understand your concerns. The fact that you live in a highly populated part of the US is all I need to know at this time. That helps me know what suggestions to make on sources of glasses or contact lenses without an official prescriptions. It varies considerably from country to country and sometimes, in the US, from state to state.

4. Dealing with your aunt’s shop is not clever under the circumstances you described. However, that may be surmountable with the right complaint about the high index lenses in your glasses. Most high index lenses do not have a very good optical characteristic called "Abbe Value". Abbe means aberration. CR-39 lenses have the lowest Index of Refraction (1.498) and the best Abbe Value ((58) of all plastic lenses. Higher Index plastics have a much lower Abbe Value and tend to separate spectrum colors based on their wave length. Chromatic Aberration usually noticeable as color fringing around bright objects. It is more pronounced at the edges of the lenses. Sometimes you can see a very strange phenomenon if you look at a Yellow LED. LEDs are very pure single wave length light sources and what we see as Yellow is actually a Red LED and a Green LED very close together. Under the right conditions lenses with extreme chromatic aberration will cause you to see two LEDs, one Red and the other Green if you are not looking exactly thru the optical center of your glasses. I urge you to look up Abbe Value of Opthalmic Lenses in your browser.

5. OK

6. See 1 above

7. See 1 above

Another question or two.

8. What math or science courses did you take in school?

9, Do you plan to continue your education?

10. Have you decided what you would like to study?

The above will help me answer your questions in terms that are understandable.

11. I may want to suggest ordering some glasses or contact lenses on line. Most require a credit card and you will need an address where they can be mailed. Does any of this present a serious problem? If so, I may have a suggestion or two. (Several clients have had similar concerns).


Jake 11 Jun 2014, 00:04

Thank you for the prompt reply, Cactus:

1. I am 18 and a half.

2. I am not exactly sure what you mean by complete prescription; all it says on my prescription is -6.25 for both eyes, with no astigmatism or another conditions (I could take a closer look at my prescription if there's something specific you're looking for, but I assume its just if I have astigmatism or any other eye conditions, which I don't).

3. I live in the US - I am a little paranoid about Internet Safety so I don't want to reveal anything more specific, but I do live in a highly populated area next to a big city, with plenty of access to anything optically-related that I might need.

4. Good question. My aunt owns an optical shop and at the time I was ordering my current glasses (this was two years ago), I wasn't as fully optically-aware as I am now, so I didn't realize that high index would eliminate so much thickness. Also, I was (and still am) kind of shy about my fetish, so I figured it would be kind of weird to ask my aunt for lower index, especially since she gave me a discount on the hi-index lenses.

5. Time interval is exactly a year, my annual exam has always been around June 1.

6. My previous prescription was also -6.25 (one year ago), and two years ago, my prescription was -4.25 both eyes (glasses), -3.75 contacts. Yes, I had a 2 diopter jump and then a 0 diopter jump :)

7. My mom is the only real myope in my immediate family; I think she reached -7.5 before she got LASIK (not sure about the exact number); none of my grandparents on either side are myopic, my dad is slightly presbyopic, and my brother is slightly myopic but it is probably from near work, not genetic (he developed it recently).

I hope these answers are thorough enough, and I'd be happy to provide any additional info as long as I can stay relatively anonymous :)

Cactus Jack 10 Jun 2014, 23:10


You have come to the right place. 7 quick questions:

1. What is your age?

2. What is your complete glasses prescription?

3. Where do you live (country and region if applicable)?

4. Why did you order hi index glasses?

5. Time interval between your current glasses prescription and the two previous prescriptions?

6. What were they if you still have them or as best you remember them?

7. Are any of your parents or grandparents myopic?

Expect more questions after you answer these. If you want some help, these are not trivial questions because they affect what we suggest.


Jake 10 Jun 2014, 20:22

This is my first eyescene post, so I better make it worthwhile :)

My prescription is -6.25 (glasses) and -5.75 (contacts); I recently graduated from high school so I'm obviously still at the stage when vision can change. Since my first prescription (-1, I believe, in second grade), my vision has gotten worse at an epic rate, but I had my annual exam two weeks ago and unfortunately my prescriptions didn't change. Argh! I have a long-running fascination for strong glasses/myopia (double digits or more), and part of the reason I mostly wear contacts is because my glasses aren't thick/strong enough (I have a full-rimmed frame with high index lenses, so my glasses really don't look/feel very strong at all). I know this sounds absurd, but I would only switch to glasses full time if they were, let's say, at least -9. I'm pretty busy and I don't have the time or money for any type of GOC, so I'm wondering if there are any other methods that I can use to make sure that my myopia deteriorates, as I'm afraid that I might be stabilizing early (sit close to the TV/Computer? Read in the dark? I don't know). Once again, I know this sounds strange (I want my strong myopia to get even worse...?), but hopefully this thread is the place to express such fantasies :) Thanks in advance.

Cactus Jack 08 Jun 2014, 07:15


In general, you are correct, contacts can potentially cause more accommodative stress than glasses of the same power. However,because of the SQUARE function involved the difference in effectiveness for creating accommodative stress between glasses and contacts ranges from trivial in glasses with prescriptions below -4.00 to very significant at say -20.00.

You used 1 diopter over correction in statement. As an interesting exercise, calculate the equivalent Contact Lens prescription for -1.00 glasses prescription and -2.00 (a -1.00 over correction. Then do the same for -20.00 and -21.00. The difference between the glasses and equivalent contact power is about -5.00 diopters at -21.00. The amount of accommodation the ciliary muscles and crystalline lenses would have to produce, assuming an eye with 0.00 refractive error is about +16.00. If the eye had some myopia, that would give it a head start on the +16.00.

There are lots of opportunities for significant errors to creep into calculating Vertex Distance effects at high powers. The accuracy of the calculations are less important when dealing with over correction for inducing myopia if there is enough accommodation range available to compensate for the errors. The potential for error in calculating for GOC applications is more important because you want any, hopefully small, error to be on the direction that allows the ciliary muscles and crystalline lenses to be able to add a small bit of plus to correct the error. Typically, GOC combos allow the ciliary muscles and crystalline lenses to be fully relaxed for distance. If the error needs LESS plus than fully relaxed, in the crystalline lenses, they can't fix the problem because they have no way to reduce their inherent PLUS power beyond fully relaxed.


Andrew 07 Jun 2014, 16:48

Surely, a 1 diopter over-correction in minus contact lenses will cause a little more accommodative stress than a 1 diopter over-correction in glasses because of the vertex distance?

Cactus Jack, 07 Jun 2014, 11:38


There is no difference in the accommodative stress caused by over correction with glasses or contact lenses.


Soundmanpt 07 Jun 2014, 11:37


Of course you can do it by wearing contacts and in some ways they are even better than wearing glasses because you are much more likely once you put them on to keep them on the entire day which is what you need to do to actually induce myopia.

Is there a reason your asking about contacts other than if it will work? If your going to be on the shy side about wearing glasses then you maybe shouldn't consider inducing myopia.

Kevin 07 Jun 2014, 08:23

If you're trying to induce myopia is wearing glasses the only way to do it or can you wear contacts too?

Cactus Jack 05 Jun 2014, 19:13


Wearing glasses with cylinder and axis (astigmatism correction) that do not match your astigmatism correction will just provide poor vision, discomfort, and probably headaches if the cylinder is substantially different from what you need and if the axis is incorrect, it just makes it worse. Astigmatism is usually caused by uneven curvature in the front surface of the cornea and you, nor anyone else, has any way to compensate except by wearing the correct cylinder and axis. You may have noticed that we always say to copy the cylinder and axis EXACTLY when ordering GOC glasses or in purchasing glasses to Induce Myopia. However, the price is right and that if very important. Why don't you try wearing them full time for a couple of days and tell us how they work. It would be very helpful if you could find out the complete prescription.


HighMyopic 05 Jun 2014, 16:09

I should have a much stronger pair of eyeglasses being given to me from a friend that wears something like -9 diopters left eye and like -8 diopters right eye. She has a lot of astigmatism. I will want to wear those glasses when out and about. My Rx is -5.50 and -4.50. Will that give me astigmatism if I wear her pair of much stronger glasses for a few hours at the time?

Cactus Jack 02 Jun 2014, 09:34

cataract idea,

Some prescription drugs may increase the likelihood of cataracts developing, but you don't want to be taking ANY medications you don't need. ALL drugs have side effects. Some of which don't show up until years later. That is one of the reasons you do not want to self medicate.

In some situations, where you do a lot of close work, AND you need crystalline lens replacement because of cataract or other condition, it is reasonable to ask that the power of your single vision IOLs be selected to make it easier to do the close work at the sacrifice of your distance vision. Typically, the selected power would be about +2.50 to +3.00 diopters over that needed to give you 0.00 refractive error (think of it as a permanent add).

Depending on where you live, there are some eye surgeons offering crystalline lens replacement with multi-focal IOLs for people who absolutely don't want to wear bifocal or trifocal glasses because of onset of presbyopia. It is not an inexpensive procedure (think $$$), but it is interesting that it is becoming an elective surgery. The snag there for you is that the purpose of elective replacement of crystalline lenses with multi-focal IOLs is to ELIMINATE the need for glasses.

Consider this. You are not too old to induce some Pseudo Myopia. In fact, increasing age, with presbyopia on the horizon, may tend to make Pseudo Myopia a bit more "permanent", but not really permanent like Axial Myopia.

Pseudo Myopia has the same optical effect as Axial Myopia. Interested?


cataract idea 02 Jun 2014, 00:27


Is thre any way to induce cataract.I thought it may be possible to ask for the new lenes strong ebough to see ok near and need single myopic glasses full time.

I am 31years old and dont need any glasses so it is to late for me to induce myopia by wearing minus lenses.

Cactus Jack 01 Jun 2014, 12:41


There are many regulatory systems in the body that seek to maintain internal body temperatures and also internal eye pressure in a narrow range. As far as is known, there is no direct relationship between air temperature and internal eye pressure. To my knowledge, there are no warnings about Saunas being a risk to vision, but my knowledge is very limited. Theoretically, raising the temperature of the surroundings for a short period of time may have some health benefits by destroying viruses. Viruses are very fragile and temperatures just a few degrees above the "normal" body temperature of 98.6 F or 37 C can kill them. It is believed that fever is one of the body's defense mechanisms. However, excessive internal temperatures (fever) can cause brain damage. Typically, a very warm Sauna or hot tub is not an issue because you will not stay in it to the point of extreme discomfort.

Failure of the eye pressure regulating system is considered to be something to be concerned about. Higher than normal eye pressures are often related to Glaucoma and excessive pressures can severely damage eye structures including the retina, leading to blindness. That is one of the reasons that periodic eye exams where the internal pressure is checked by either a puff of air (which requires no anesthesia) or a "gold standard" check using a calibrated device that applies gentle pressure to the cornea and measures the deflection that results from the pressure. Those tests require the administration of anesthetizing drops because the cornea is extremely sensitive to foreign objects touching it.


HighMyopic 31 May 2014, 14:58

I have been wearing a slightly stronger pair of thrift store glasses when out with my physician and when at bowling with my special needs group. My latest rx is -5.50 and -4.50. I was at MacDonald's yesterday and noticed that the menu was slightly blurry. I would like to wear a -6.50L lense and a -5.50R lense. I have a couple of pairs of glasses coming in the mail from a close friend. I hope that they are very strong and I can wear them and get my eyes used to them. I am 22 years old.

choch 29 May 2014, 11:40

when tires heat up the the pressure goes up. i figured it would be similar with an eye. and normally when the pressure goes up in an eye even temporarily the body responds by elongating it. so i was thinking more along the lines of not dehydrating yourself drastically

Cactus Jack 29 May 2014, 09:15


I have never heard of anything like that. I guess it might, if you did it long enough to get severely dehydrated to the point where it affected tear production or the water content of the components of the eye. I think it would have more serious effects on other parts of the body before that happened.


choch 29 May 2014, 00:07


Do you think that prolonged sauna use could have an effect on refraction needs?

svensont 27 May 2014, 18:51


I have never been caught doing it, so nobody knows what I'm doing. I come back home always in contacts and they even don't suspect anything. It's time to tell them

svensont 27 May 2014, 18:49


Do you notice a "morning blurriness"? I used to have it when I was wearing the glasses before going to bed, even for a short time.

When I was not wearing glasses, I was trying to keep the blur as long as I could, sometimes even for a full day. That helps a lot, because then your eyes are not relaxing.

What are your plans for next prescription?

til 27 May 2014, 18:44


And the thing about inducing myopia, I'm not really sure about. I enjoy wearing glasses, even more with a 'decent' prescription but I don't like the thought of depending on them. As far as I can think now I'll be most happy if I can comfortably accommodate glasses about -5 but I'd leave it then.

How did your family/friends/girlfriend react to you with glasses or didn't they ever see you wearing them?

til 27 May 2014, 18:37


Actually it only takes me a second or so to get things into focus both ways. My family isn't very aware of me wearing glasses as they don't live nearby. Some of them know I "need" glasses because I forged my first prescription at the age of fourteen. And I doubt any of them can tell the difference between say -1 and -3 or even +1 and -3. Btw I think hardly anybody can apart from ECPs and OOs. The only tricky thing is friends, especially girls, when they try my glasses on and react like "last time I could see a lot better in your glasses, do your eyes worsen that quickly?". I haven't really found a good story about that yet.

svensont 27 May 2014, 17:41


I started inducing myopia when I was 23, at first with -0.5D, then -1.5, and finally -3.5 glasses. I was wearing them only part time (when nobody sees me). About 8 months later I went for eye exam and got a prescription of -0.5D -0.25cyl both eyes. Then I ordered -4D and -5.5D glasses, was wearing them part time too. I was also experimenting with contacts, the strongest were -4.25D and I could see perfectly in them, the same in glasses -5.5D, I could read very small print in them comfortably. Now I am 26, in February I had another eye tests, the results were L: -0.25D -0.5cyl, R: -0.25D -0.5cyl (another optician: L: -0.5D -0.5cyl, R: -0.75D -0.5cyl). In my case I "induced" astigmatism and a little bit of myopia, as I had perfect eyesight before. Now I'm wearing glasses -0.75D -0.5cyl left and -1D -0.5cyl right and contacts L: -0.5D -0.75cyl, R: -0.75D -0.75cyl.

I think you can induce some myopia. When you take glasses/contacts off, how long does it take your vision to return back to normal? What was the reaction of your relatives when you appeared in so strong glasses?

I have been wearing the -3 glasses on and off since last october I think. In december I bought -3.5 contacts and ever since then i either wore glasses or contacts. About a month ago I got contacts of -4.5.

There hasn't been any noticeable change yet but I didn't expect anything really. The only thing I notice is that when I first got the -3s I could just about see in them. If I understand Cactus Jack's vertex distance calculations right it would mean that I could accommodate just under 3 diopters. Now I'm fine with 4.5 diopters difference.

I don't expect to be able to induce myopia though, I'm 26 and there is no history of myopia in my family.

How long and how often have you been wearing your glasses? Have your eyes changed a bit?

I see the reasons for the bifocal/progressive suggestion but she wouldn't like going down that road, and to be honest me neither.

Any thoughts on the headache or blurry vision mentioned below?

Cactus Jack, Soundmanpt

She is 25, and wearing these glasses to work is out of the question at the moment, she hardly ever wears her own glasses.

The reason for the uneven change in prescription was actually down to her. She went to an optitian she knows personally, not an eyedoctor though, to see what she could cope with. I think the reason behind this is that she doesn't like the difference between her eyes although it's hardly visible.

If your gf is able to see distance with the minus prescription reasonably well but not surprising that her close vision could be a problem for her if she is intending on wearing while doing her job. The solution is simple, just order her a pair of bifocals or progressives that way allowing her to see close up without a problem. Like Cactus Jack said my guess is she is probably past the age to actually induce ny reap myopia but she may still be able to wear a minus prescription without a problem for her distance.

You effectively reduced her plus prescription through 0.00 to -1.00/-1.50 a change of -2.75/-2.50. She just has to accommodate to focus close by using her ciliary muscles and crystalline lenses to add the necessary plus internally to compensate..

You didn't mention her age, but accommodation to focus close may be an issue for her and I suspect that she may be beyond the age where she can accommodate for the reduced plus easily or comfortably. I suspect she may be too old to induce and axial or true myopia or significantly reduce her hyperopia. She may be able to induce a bit of Pseudo or false myopia, but it will take some work.

May I ask why you did not reduce the sphere in her glasses by the same amount in each eye? If she would like to try to reduce her hyperopia, I would suggest a smaller change to help her to condition her ciliary muscles before attempting very much of a change. It is typically very counterproductive to change a prescription enough that it affects a persons ability to do their job easily and comfortably.

I just received two pairs of glasses, one for me and one for my girlfriend. She's a natural +1.75/+1.00 plus astigmatism and I don't need any correction but have been challenging my accommodation lately. I already have a pair of -3 and just got this one with -4 lenses. Seeing me wearing the -3s comfortably made her curious and she'd be happy ( but not too eager ) to reduce her prescription or even get myopic if that should be possible. I ordered her a pair of -1/-1.5 and astigmatism correction and she seems comfortable apart from reading.

Today she asked if there could be any side effects to this like having blurry vision the next day or headaches. I told her I don't know and she should find out slowly (she works in a lab). Is there anything to expect when you actually have a plus prescription?

What is the point of trying to cheat the auto refractor. These days, it is better to get the most accurate prescription you can from the ECP and order the prescription you want, online. Your actual prescription, particularly the cylinder and axis, in addition to the sphere is the starting point. Just remember that what you want to change is the sphere and never the cylinder and axis.

Hi, anyone tried to cheat the autoref. As i said?

Cactus Jack 19 May 2014, 01:27


It is both theoretically and practically true that a person’s myopia can be increased by refractive surgery. All that is necessary is to increase the total PLUS power of the eye’s lens system. There are several ways to do this:

1. Laser Cirugy (Surgery) - Laser Surgery can be used to sculpture the shape of the cornea and increase its PLUS power. Normally this procedure would be used to correct a person’s Hyperopia, but there is no reason why it could not be used to increase Myopia. There are practical limits to the amount of increase that is possible depending on the thickness of the cornea. The big problem would be finding an eye surgeon who would perform the procedure.

2. Internal “Contact Lenses” - Internal contact lenses would be a much better choice. These lenses are inserted in the eye between the cornea and the iris through a tiny slit in the side of the cornea. These lenses can be removed and replaced. They are available in a wide range of powers.

3. Intra Ocular Lenses (IOLs) - Normally, IOLs are used as crystalline lens replacements for natural lenses clouded by cataract, but more recently, with the development of high performance multi-focal IOLs people are electing to have them installed in non-cataract situations to avoid wearing bifocals or trifocals. This procedure has the side benefits of never having to worry about cataract surgery because it has already been done. IOLs are permanent and cannot be easily changed.

In all instances, the problem is finding an eye surgeon who will do the procedure.

If I am not mistaken, you have been posting for quite some time about wanting to increase your myopia, apparently without success. If that is correct, could you please provide your age, current complete prescription, and the prescription you would like to have.

Thank you; yes it does make sense!

For me it is possible to induce myopia by wearing glasses in my case it was glasses for farsightedness that I wear, but I did that not enough young I was 14 and about I had my first myopic glasses at the age of 15 and a half years -1.50

Lalau 18 May 2014, 05:35

Is there any known case of a person really persistant to be myopic, that realize a laser cirurgy to become myopic? Anybody in this site know any case like these? In teory, it´s possible right?

I manage to upload the instructions, at this link:

Tell me if it's comprehensible or not.

I think we'd all like to hear how to trick the autorefractor!

Hi, it's not difficult to cheat The autoref...tell me your email address and i'll explain what you have to do.

gogogo 16 May 2014, 01:12

The only possibility in my knowledge, is to say to that you are diabetic, and have some transiente myopia, but in this case, he would probably still ask you to do a diabetes exam... In this case again, is impossible to trick the blood exam. =p

You make a big mistake by telling your HR person that you have bad eyesight. Your company understands that if their employees have any issues with seeing properly the quality of work will suffer. So in the end your company benefits by supplying an eye exam as well as glasses when there needed. A small investment for having employees seeing more accurately.

Now your in a bad spot because there is no way to trick the exam and coming away with enough of a prescription to make any difference.

Now you need to start thinking what your going to say to that HR person when they see the results of your eye exam and see that your eyes barely have a prescription.

is it somehow possible to trick auto refractometer?

I have my work eye check coming in next week and I am bit in a trouble.

Actually it is not important am I near or farsighted. I have obsession for glasses and I told to my HR manager that I see quite bad. What I actually don't and now they made me optometrist appointment and as I see in my pay-cheque gave compensation for glasses. In return they said that they need my prescription for the records. I talked about ordering online and asked if invoice is good for them but it is not because they need my rx to see next time has it changed and if it is they need to pay new compensation.

My current prescription from auto refractometer is left -0,25 +0,25 and some degrees. Right 00 -0,25 and some degrees.

I actually tried to wear my wife glasses what are around -3 for some time and have an eye test then but still did pass it. I don't know refractometer measurements but optometrist tried 4-5 times some lenses and then he understand somehow that I was cheating and said that I don't need glasses.

I live in a quite small down and we have about 6 optical shops who can do eye exam. I have been in two of them already. And 2 I can not go because my sisters friends are working there. So I probably could go for one test run in another store and then I have this place where I should go from work.

Please give me some advice

Eyestien, I was outside all the talk me as child, im currently -6.50/-5.25 with astigmatism, so not sure if I buy into that.

Eyestein 08 May 2014, 06:48

Does anyone have a comment about this article? It's sort of related to the current discussion.

Apparently sunlight can counteract whatever hormonal or biochemical stimulus induces myopia - at least at an early age.

Long before the internet,and the popularity of yogurt, there was some rumor going around that the consumption of large amounts of yogurt was a cause on moderate myopia.The rumor centered around a satellite country o
