What your asking is very difficult to answer. Getting glasses is actually very easy to do and you don't need a prescription to order a pair, but just saying you want "strong glasses" makes it hard to suggest what prescription you should order. If you have perfect eyesight and your mainly just interested in wearing glasses that's fine. But you need to order glasses that your eyes will adjust to. Also going from no glasses to suddenly wearing strong glasses will get you lots of unwanted questions from your friends and co workers as well as family. You would be best to start off with very average glasses and as your eyes adjust slowly increase to stronger glasses. As for where to get your glasses I always recommend "zennioptical.com" but "eyebuydirect.com" is also very good and both have a nice large selection of glasses for under $13.00. Zenni actually has a decent selection for under $7.00. For first glasses if you have perfect eyesight I would sya either order -.50 or -.75 for both eyes in the SPH section and leave everything else open. You don't want to fill anything in the CYL or axis areas. You might want to consider getting the optional AR coating which cuts down on glare and reflections and will make wearing glasses even easier for you. I also suggest thatg you answer Cactus Jack's questions because the things he is asking you are important as well.

Oh and you're in the GOC thread is that what you're really wanting to do? If so there is a lot more to it because of needing contacts as well.


Cactus Jack 02 Mar 2017, 08:47

Leah,

An "Official" prescription is one issued by an Eye Care Professional, typically after an examination.

Glasses are custom made. The people who make glasses need a prescription to know how to make them. Most online retailers of glasses do not require that you provide an "Official" prescription, but they need information from you as to the various elements that make up the prescription. They are for each eye:

Sphere Power, Cylinder Power, Cylinder Axis, Prism Amount, Prism Base Direction, and Add plus special instructions such as the type of bifocal or trifocal.

The also need your Pupillary Distance, which is the distance in mm between the centers of your two pupils.

Not all prescriptions have all elements, but they are typically listed in the above order.

You can t just order "Strong Glasses". The most important thing is that the glasses you order be wearable and comfortable. Otherwise, they are a waste of money and can be very unpleasant to wear.

Leah 02 Mar 2017, 06:36

What does that mean (it doesn't have to be an "official" one)?


Cactus Jack 01 Mar 2017, 23:11

Leah,

You can get them online with a "prescription", but it does not have to be an official one.

You should not attempt GOC without a plan and some coaching. It is tempting to go to a high glasses prescription, but that generally does not work out very well. Your brain has to learn to "see" with strong glasses and that can be somewhat traumatic, unless you approach it right.

If you want some help, you need to tell us more about yourself:

1. Do you presently wear vision correction? (Glasses or Contacts - which)

2. What is your prescription?

3. Where do you live.

4. What is your age and gender?

5. What is your GOC goal? (Approximate glasses prescription)

6. What is your occupation?

I posted about this way back in 2013, but you might enjoy hearing about it. It really started back in 2012. I used to visit my sister that was living in a different city. Whenever I visited her I also visited the local shopping mall. In the mall there was an optical store. I would usually plan my visits so i could visit on the days when they didn't have a doctor. That meant there was only one optician working and she usually wasn't busy at all. In 2012 they hired a new optician. Very cute young lady and she was hired because she was about to enter optometry school to be an optometrist. Anyway she very nice and very friendly and we talked quite a bit. I noticed that she wasn't wearing glasses and I asked her if she wore glasses and she said her eyesight was perfect. She told me that her dad was a dentist and her older sister was a pharmacist and that they both wear glasses full time, but her eyesight was perfect. She told me that when she decided that she wanted to be an optometrist she knew nothing about glasses but was very curious to know. While her sister was away at college she even went in her room and found several pairs of her old glasses and tried to wear them just to see what it was like to wear glasses. But even the weakest ones she could only wear for very short time before she felt a headache coming on and she had to take them off. That caused me to remember what I had read in this thread about GOC. I work with a non profit vision group and because of that I happened to have a good number of sample glasses that I keep in my car that I use to fit people with glasses that can't afford them. At the time I knew i had a very nice pair with just a -1.25 prescription in them. I told her to go and pull out a pair of trial contact lenses in +1.25 and that I would be right back in. When I came back in she was sitting at a table and she had 2 contact lens packets in her hands. She thought that I wanted them for myself so she was really shocked when I asked her to put them on. She got them both on rather quickly and I as soon s she looked away from the mirror in front of her I could see that she wasn't able to focus. She was smiling and squinting as she was trying hard to see things away from her. I asked her if she was able to read a sign across the room from where we were sitting and she could only make out the bigger letters and she said they were even blurry. I took the glasses out and said "here let's see if these help you" as i put the glasses on her. As soon as I did that she couldn't believe that now she was once again able to see everything perfectly. As you can imagine she was then doing a lot of her own testing of her eyes with and without glasses. But the whole time she had the biggest smile on her face. After several minutes of both looking through the glasses and over the top of them she finally pushed the glasses up in place and said she loved it. She said several times how cool it was to be wearing glasses. We continued talking and she never did take the glasses off she was totally enjoying wearing glasses. After a while a customer came in and needed the nose pads on his glasses replaced. This was going ot be a nice test for for her trying to replace nose pads that have very tiny screws wearing glasses for the first time. I watched her to see if she was going to have any problem and I did notice her move her head a bit as if she was having trouble focusing. But after a few minuted she had both nose pads replaced and he thanked her and left. When she came i asked her if she had any problem doing that and she said that when she first looked down her eyes were seeing the bottom of the glasses so she had to adjust for that. I didn't plan on leaving my sample glasses with her but she was having so much fun so i asked her if she wanted to borrow them until my next visit and she jumped at the chance to wear the glasses more. As it turned out I didn't get back until a month later. She told me that the doctor and her co workers were shocked to see her come into work wearing glasses. She told them about me loaning her the glasses and how she was wearing the opposite contacts to make it work. The doctor was very interested and had never heard of such a thing as GOC and she insisted on testing her eyes with and with her wearing GOC just to be sure that she wasn't doing any harm to her eyes but she proved that with the contacts and glasses her eyesight was perfect as well as without the contacts and glasses. The doctor even said that she was going to have to remember that because she was going to try it for herself. I still keep in touch with her last year she graduated and she is now officially a doctor of optometry. She decided to move out of state for some reason but she told me not long ago that she still enjoys doing GOC just for fun and has shown a good number of people as well.

The other one was a young lady working at a big box store that has an optical center. She also didn't need glasses. In box stores like that they often hire you for one thing and then put you in something else. That was the case here. She had no experience with vision or glasses at all. But once she got trained she really enjoyed her kob. One day when I was in there shopping I stopped and chatted with her a bit. She was at the frame board trying on frames. As soon as she saw me she wanted my opinion as to which ones looked best on her. After a bit i decided on the one I thought looked best and she said that was her 2nd choice but was happy I picked it. She told me that her year was nearly up and that meant she could get a free pair of glasses. I asked her if she needed glasses and she said she wasn't sure but even if she didn't she still wanted a pair of glasses just to wear for fun and at the store as well. She was getting her eyes checked later that week. The next tie I was at her store i saw her working but she wasn't wearing glasses. I asked her if she had gotten her glasses yet and she told me she wasn't very happy. She said that her eyesight was perfect so she didn't really need glasses. But when she went order her glasses she was told that because she didn't have an actual prescription she couldn't get a free pair. Bingo! Remembering how I helped my other friend with perfect vision I still had the very same -1.25 glasses so I told her how she could get glasse sif she wanted and I let her borrow my sample pair to try away from works so she could see that it wouldn't dod any harm to her eyes. She was able to get the glasses she wanted that way and she couldn't stop thanking me.

Sorry for the long post.

I'm really glad that you're enjoying doing GOC so much. Actually you were a perfect candidate for doing GOC because you were already an experienced contact lens wearer as well as glasses wearer and you clearly like how your husband's glasses look. So with Cactus Jack's help in prescribing you a perfect combination for both contacts and glasses you seem to be enjoying perfect clarity now after a normal adjusting period. One thing you didn't mention which I have a feeling you also enjoy is seeing how much more blurry everything is when you take off your -9.00 glasses compared to your own glasses? It's possible that your eyes might be very slightly over corrected but that's not a bad thing because it's worse to be under corrected. The lenses in your glasses are most likely CR-39 which is what they consider regular lenses, so with -9.00 prescription lenses i'm sure they look nice and thick. I'm not surprised that you are planning if not already making GOC your everyday look now and not just something fun to do on the weekend.

So it seems that your friend is wanting to as you say "join the GOC" club now. It helps that she already wears glasses. Does she wear her glasses full time or part time? And I have a feeling since her prescription isn't very strong I doubt that she has ever wore contacts? So for her the first step she need to do is make an appointment to get contacts. Probably not a bad idea depending when she got her current glasses. When she goes she should be sure to get a copy of her glasses prescription as well as the contact prescription and fitting. The fitting is the main thing and tell her not to bother ordering any contacts in her real prescription unless she really wants contacts in her actual prescription. Once she has the base curve and diameter for her contacts she will be ready to start looking for the glasses she wants to wear and you can help her order the correct contacts to go along with her glasses. Is she wanting her glasses to be as strong as yours?


juliette 01 Mar 2017, 02:57

Hello Soundman

Your posting really confirms what I feel with these new glasses, I feel much more self assured, self confidence, & more over feel I look much more sophisticated with this GOC combination. But besides this the clarity of my vision is amazing, & I really couldn't imagine it could be so good doing GOC as its called. As you said the lenses I assume are CR 30 something, low index, & have flat fronts & on the outer edges they must be around 10mm thick, & look stunning.

It was a typing error on the power, & I did use 10.50 Biofinity XR for the exercise. The first couple of days I felt a little bit dizzy but that's gone. The whole experience is great, & I intend doing it daily, & hope I can work up to -12.00/-14.00.

Yes my friend does wear glasses, I think her prescription is around -1.5, but she intends to join the 'Club' as someone said.

Thanks to everyone for support & advice..its great


Cactus Jack 27 Feb 2017, 13:01

Brit,

Here are the calculations assuming a Vertex Distance of 12 mm.

20^2 = 400 /1000 = 0.4 diopters per mm x 12 mm = 4.8

OOPS!.

I made a mistake. I should have added the 4.8 to the +20 for PLUS glasses VD effect. I do so many calculations for MINUS glasses that I inadvertently subtracted. The CLs for +20 glasses should be -25.00. Theoretically, it should be about -24.8 assuming a VD of 12 mm. The VD is a SWAG and with +/-20 glasses it is a major factor. If a person is not too old, I suggest a little more MINUS or a little less PLUS that I think you will need because your Ciliary Muscles and Crystalline Lenses should be able to add a little PLUS to compensate.

Thanks for calling this to my attention.

plusglasslov,

Please note the change in the suggested GOC combination. Please DO NOT buy any glasses or contacts until we discuss this further.

C.


Brit 27 Feb 2017, 12:21

Cactus are you sure about the previous posting?


Cactus Jack 27 Feb 2017, 10:57

plusglasslov,

To answer your specific question, you need approximately -15 contact lenses to go with +20 glasses, assuming you have perfect uncorrected vision and have enough accommodation range to compensate slightly for any errors. If you don't know why there is a difference between the power of the Glasses and the Contact Lenses, you probably need some serious coaching.

If you want to do successful GOC we need to start with answers to these questions:

1. How old are you?

2. Where do you live?

3. What is your latest glasses prescription?

4. Have you ever worn Contact Lenses?

You need to approach high prescription GOC slowly, carefully and with planning.

Based on the answers to the above questions, there will probably be more questions.

C.

hello.

can any one suggest me what would be an ideal pair of contact lens power ,if i want to wear +20 glasses


Soundmanpt 26 Feb 2017, 10:51

Hasan

Okay now I get what you did and why. So she avoided even wearing her own prescription glasses because her eyes appear slightly smaller under her glasses. And her prescription is only a -1.50 which to most people would hardly be noticeable. So you first needed to get her started wearing glasses and you were able to convince her by getting her emerald green minus colored contacts which she must have liked because they enhanced the color of her eyes and then had her pick out glasses that suited her with plus lenses to match up with her contacts. And of course she likes seeing her nice big green eyes so she has been more than willing to wear her glasses and has found out that doing GOC hasn't done any harm to her eyes. But your real goal is to get her wearing stronger minus glasses for GOC. But for whatever reason finding plus colored contacts is much harder to find in plus than minus prescriptions. So that is one problem. But even if you do find them I think your wife would be disappointed as soon as she put on the -5.00 glasses over her eyes. The green contacts would hardly be noticeable to her under her glasses. There would be a huge difference for her seeing her eyes wearing +4.00 glasses and then seeing her eyes wearing -5.00 glasses. Maybe have her pick out glasses if she already hasn't that she likes and just find clear +3.50 contacts to see if it is worth looking any harder for the green color. As you know the glasses won't be very expensive and if you can order just one box of lenses they shouldn't be much either. And maybe she won't be happy at first but if she likes the glasses enough she might decide to give it a try after a while. Other wise you still have the option of seeing her wearing the combination she has now and she seems to enjoy wearing. Also if she wears the GOC often enough she will find that she needs to wear her own prescription glasses when she isn't doing GOC.


Hasan 26 Feb 2017, 05:03

Soundmanpt,

Plus glasses was the first step in my plan. The only way not to make her eyes look smaller with glasses was GOC. We`ve made it using emerald green colour lences - big green eyes was necessary requirement. Now when she had understood that there is nothing harmful in GOC and she got used to it with "her" combination", I`m gonna convince her to try "my" combination with minus glasses. The only problem - I didn`t found colour plus lences yet.


Soundmanpt 25 Feb 2017, 10:38

Hasan

Sorry about that. It's just that it is a bit unusual for someone already a bit nearsighted to want to want plus glasses. But it makes sense if she didn't want her eyes to look smaller under her glasses. But now it seems that she is going to try wearing minus glasses if she is wanting to get +3.50 lenses and -5.00 glasses. Is she now okay with her eyes appearing slightly smaller under her glasses?


Soundmanpt 25 Feb 2017, 10:28

juliette

Since your husband wears -14.00 glasses i'm not at all surprised that he is loves seeing you wearing glasses nearly as strong as his glasses and of course supports you fully. I'm sure that your glasses look really nice in that frame you chose as well as your nice thick lenses. So i'm sure you must really enjoy wearing them every chance you get. It's always interesting how wearing glasses effects some women. Certainly for many wearing glasses seems to change their whole additude and they way thye see themselves. And for some like yourself it is more like an empowerment and provides you even more self confidence. I can only assume it's because you have wanted stronger glasses for so long and now that you have them you feel like you could conquer the world. Did you go with the combination that Cactus Jack suggested to you? I did notice that he was suggesting you order +10.50 SPH only contacts to go with -9.00 glasses but then you asking where you might be able to order +10.25 contacts? Not that much difference if that is what you actually ordered. Where were you able to get your contacts from? It has gotten more difficult recently to order contacts without a doctor's approval. Your friend seemed impressed enough at your glasses that after trying your glasses is wanting to try it herself. Of course i'm sure you would help her in getting a combination that will work for her. Does she currently wear glasses or would this be her first time wearing glasses? If so she probably needs to start off much weaker.


Hasan 25 Feb 2017, 03:14

Soundmanpt, I`m really excited, but there is no mistake - now she wears -4.0 lences with +2.5 glasses. All this story started long time ago. My wife always was little bit nearsighted and even she had glasses, she never used them. Sometimes I succeded to convince her to put them on for me but she always said that she don`t like her eyes look smaller in glasses. GOC become a good idea in this situation. Plus glasses makes her eyes look bigger and we both like that.


antonio 24 Feb 2017, 14:41

Hi Juliette,

just curious, what Kombination do you war now?

Thanks and Best regards, antonio


juliette 24 Feb 2017, 11:05

Rafa , thanks for your post. My partner supports it, & is pleased to see me in these stronger glasses. I chose a roundish frame in a tortoiseshell finish. I find I look great in them, & somehow feel more self assured, but maybe that's because, I have wanted thicker, stronger looking glasses for some time now. Friends, also find I look good in them, & one of them is going to give GOC a try, as she had the same good feeling when she tried my glasses. I will when the time is right try to go up to a higher level. In the meantime I will continue to enjoy the experience as it appears so many other here do!


Soundmanpt 24 Feb 2017, 08:54

Hason

I think that you were so excited seeing your wife wearing stronger glasses that you made an error about her current combination? You said that she is now wearing -4.00 lenses with +2.50 glasses. I think what you meant to say was that she is wearing +2.50 lenses with -4.00 glasses? It's clear that you appreciate her looks wearing stronger glasses and I would assume since she didn't go overly strong her eyesight should be very good with her -4.00 glasses and +2.50 contacts. The one thing she need to be careful with is changing from one glasses frame to a different frame in a short time could lead to extra unwanted questions about her glasses, not the lenses. so if she is considering going stronger anytime soon she should try and order the exact same frame as her -4.00 glasses.


Hasan 24 Feb 2017, 04:16

Finally it happaned! My wife started wearing GOC. Her real prescribtion is -1.5 on both eyes. She sometimes wears -4 lences and +2.5 glasses. In this glasses she looks really great! Now we are thinking about combination of +3.5 lences and -5 glasses.


rafa 24 Feb 2017, 02:36

Juliette

Welcome to the club! I'm glad GOC is working good for you.

I myself started GOC'ing around june last year, and after a few dizzing problems in the beginning, I've adapted really well. I started with -9 glasses and have now worked my way up to -20. So I'm sure you too will adapt well to stronger lenses soon.

Tell us more about your experience. How's the feeling of seeing youself in those thick lenses? What sort of frames did you choose? And how is your husband reacting to it? Does he like it? Has anybody aside your husband seen you and noticed something different?


juliette 24 Feb 2017, 02:01

In the later part of last year, I came across this site, & the section 'Glasses over contacts'. As I explained, I didn't know at the time this was possible. With the feedback I received, it was a chance for me to get stronger, thicker more powerful glasses that I had wanted for a long time. I have now been doing GOC for around 6 weeks. The first few days it felt a little strange, but with perseverance, I can now wear the combination all day with comfort..it really works well. I now feel & look as though I need glasses, & I feel great in them. I intend to persist with them which at present is not a problem, & before the holidays try to increase to somewhat stronger lenses if possible. It is really a nice experience & I can now fully understand those who like & want these stronger thicker glasses.


NNVisitor 19 Feb 2017, 22:13

You are best off just wearing your own prescription. I've had really bad eyesight and wore strong glasses. If people took notice of that fact they rarely showed it. I wore thick glasses before there was the thin option. I hated wearing them and was selfconsious. I did get some comments about them and my eyesight but not very often. I did get contact lenses which I've mostly worn for many years.

The reality is that many people wear glasses and that some people wear strong glasses. As most people are concerned about their own problems it's really no big deal if they see others wearing strong glasses. I doubt that if you wore -4 or -6.50 that people would take special notice. So why go through all the effort? You are best off wearing the prescription you need.


gwgs 18 Feb 2017, 03:44

You could also try Firmoo- they do regular 1.5 index lenses which are the thickest option available to you, I don't know how they compare on price though but they often have offers available especially for new customers


Soundmanpt 14 Feb 2017, 11:11

Diana

Okay now that you have made it clear what your wanting for glasses that is a big help. So if you want the cheapest and thickest lenses possible I think you want Zenni. You will find a good number of glasses for $6.95 and that is including prescription lenses. It will ask you "Prescription type" and where it says "Select" you will be given a choice of single vision, bifocal, progressive, non-prescription, and frame only. Of course you want to click on "Single Vision" Then if you want -4.00 glasses you simply click on the -4.00 in the SPH column for both eyes and the next step it will show you various lens options. The first being 1.50 which they call a standard single vision lens and is no additional charge. Then you see a 1.57 lens which they call mid index single vision and it si also no additional charge and then there are other lenses as well. Zenni is suggesting for best looks and thing lenses that you get the 1.61 high index lens which is an additional charge. But you don't have to got that and you simply click on the first option of 1.50 and that should be a rather thick lens. The reason they offer both a 1.50 and 1.57 lens is because for someone getting glasses with just a a -.50 prescription a rimless frame would be extremely thin if they only offered the 1.57 lens. So I don't think you are going to find any glasses cheaper than $6.95 and shipping is only $5.00. So that adds up to $12.00.

But once again I am reminding you that to do this right and so you're happy once you get your glasses and contacts you really do need to get your exact current prescription. I'm sure Cactus Jack will agree with me and he will also tell you that you need to get a fitting done for contacts. By the way it has gotten much more difficult buying contacts anymore without a real prescription. Have you done any research on getting the contacts you're going to need?


Cactus Jack 14 Feb 2017, 10:27

Diana,

Check out Optical4less. I don't know their current policy, but they used to have a special makings department. They would make glasses of any reasonable thickness with almost any prescription. They are not cheap, but their quality is excellent.

Also, check out what Zenni will do. They may suggest a thinner lens, but you may be able to select a lower index lens material.

C.


Diana 14 Feb 2017, 10:04

I want the thickest, cheapest glasses possible. Preferably without losing my natural vision.

I was planning on purchasing a -6.75 prescription from Swift Eyewear but they forced me to pay for thin lenses. I don't want to do that. That's why I decided to get the -4s with a 1.49 index lens. I was hoping that they'd still be very thick because I want to look like I'm wearing cokebottles.


gwgs 14 Feb 2017, 02:20

Amy, -4 won't be anywhere near coke bottle status, but an easy way / general rule I've found is that for ever dioptre, i.e. every -1, the lenses will be about 1mm thick. The bigger the frame the thicker the lenses at the outside edge, but generally you won't be looking at anymore than a maximum I would've thought of about 3mm thick at the edge.

The following website is a good way of working out how thick lenses will be, but it can vary slightly. As you will see, you will need to know the measurements of the frame to work this out and your pupillary distance which if you don't have it / haven't had it measured is on average between 60 and 62mm.

http://64.50.176.246/tools/thickness.php

Hope this helps.


Soundmanpt 13 Feb 2017, 15:28

Diana

What exactly are you wanting to wear stronger glasses for? My first thought was that you just want your glasses to look more necessary than they are. So if anything you would be happier if your lenses did look thick and strong. But you actually would be happier to wear even stronger glasses as long as the lenses aren't too thick. And you don't seem to want to cause your own natural eyesight to get any worse but want people to think your eyesight is poor.

Where are you planning on getting your glasses from and what style of glasses do you plan on getting? Many in here use Zenni (zennioptical.com) for their glasses to induce myopia with or for doing GOC. They do offer two lens thicknesses at no additional cost 1.50 and 1.57 the 1.57 is a slightly thinner lens which is what you're asking about. They do offer several options for hi index lenses as well they are 1.61 for an additional $19.00 and a 1.67 which is a $34.00 option.

So how did you come up with your SPH equivalent being -2.50? It almost sounds like you did some type of on line vision test? So if that is accurate then the contacts would be +1.50. That isn't all that much more to get to -4.00. Have you given any thought to just buying -4.00 glasses or even maybe -3.50 glasses and wearing them without the contacts? Your eyes should be able to tolerate wearing -3.50 glasses pretty well


Diana 13 Feb 2017, 14:22

Found out that my spherical equivalent is actually -2.50

Wanted to go higher than -4.00 but don't want to have to pay for the thin lenses. They don't give you the option of buying higher prescriptions in CR39. Would -4 in CR39 be cokebottles?


Soundmanpt 12 Feb 2017, 11:28

Diana

In order to provide you with an accurate answer for the contact lens power that you would need to go along with -4.00 glasses you really need to be exact with what your current glasses are. Based on your glasses being between -1.75 and -2.25 it could be any of these.

If your glasses are -1.75 then you would need +2.25 contacts

if your glasses are -2.00 then you would need +2.00 contacts

if your glasses are -2.25 then you would need +1.75 contacts

Now if you decide to guess that your glasses are -1.75 and order +2.25 contacts and your glasses are actually -2.25 then your eyes are going to be over corrected wearing the -4.00 glasses. Not the worst thing that could happen because your eyes would probably adjust okay to wearing the stronger over all prescription. But it could be a bigger problem for you if your glasses are -2.25 and you order the +1.75 contacts and then find out that your glasses are only -1.75. Now wearing your -4.00 glasses your eyes would be under corrected and that would mean that your distance vision would be somewhat blurry and you probably couldn't wear your -4.00 glasses for driving. So I really recommend that you first find out what prescription you're currently wearing before buying anything. If you have had your eyes checked in the past 12 months or so then if you go back to where you either had your eyes examined or where you got your current glasses from they will gladly provie you with a copy of your prescription. If it has been much longer since you had your eyes examined then you probably need to get your eyes examined anyway because it's possible your eyes have changed a bit since your last exam. Its even possible that you might have a small astigmatism and don't know it. All this information will make it very easy to then suggest what you need for contacts so you can wear -4.00 glasses in comfort and be able to see perfectly as well. I have feeling since your not trying to go to extremes you are only wanting your glasses to look more necessary and plan on wearing them quite often once you get the right combination of glasses and contacts.

Current prescription: between -1.75 and -2.25

Want to wear: -4.00

What contacts should I get?

hi there. I'm getting some plus contacts in the power of -8 and -25 online. They require a prescription to be sent over by email. How do I fake a convincing prescription with no cylinder? Can someone help?

Ps... I'm a seasoned GOC user. Have done with contacts of -5 up to -22 so do not worry about my experience with GOC. It's just that so far I managed to get contacts without a need for prescription.

Once again I stand corrected. I now see that he was also planning on having the cylinder put into her glasses and not her contacts. As always i am blaming it on old age.

Soundmanpt,

Absolutely! Good point. Til was asking about GOC with +5.00 contacts and the proposed GOC glasses had the Cylinder and Axis part of the prescription in them.

If you are going to do GOC there is no point in messing with Toric contacts.

Shouldn't she get her cylinder put into her glasses rather than deal with the more expensive and less comfortable toric lenses? I also agree with both of you that at least for her first attempt at GOC going with -3.00 glasses would not only look very nice for her glasses but probably easier for her to adjust to for frequent wearing. I assume she is considering making these her everyday glasses?


Cactus Jack 03 Feb 2017, 07:55

til,

That sounds about right for GOC contacts and -3 glasses. If the glasses are less than - 4 to - 4.5, they will have almost no Vertex Distance effects. You can just algebraically add the GOC CL prescription to their GOC glasses prescription. Just remember that corrective lens prescriptions are the reverse of the actual refractive error.

The nice thing about a good GOC combo is that little or no accommodative effort is needed, If she goes for a GOC combo with glasses above -4.50 in Sphere, you will need to consider VD effects of the glasses. Just remember that VD INCREASES the effective power of MINUS glasses at the Cornea so you need LESS power in the contacts and DECREASES at the effective power of PLUS glasses at the Cornea so you need MORE power in the contacts.

Sounds confusing? Yes it is, and that is why those of us who understand it make the BIG MONEY and/or get nice Birthday presents. Enjoy!

Toric contacts are notoriously hard to get right so they don't rotate on the Cornea and make Astigmatism effects worse than not having any Cylinder correction.

I had the most exiting been birthday present by my girlfriend this year. She is a hyperope and knows I very much like the look of minus lenses so she is gonna go for GOC now:)

She has a glasses prescription a little less than a year old

L +1,50 -0,5 148

R +2,00 -1,0 54

She is currently getting fitted for contacts (takes quite a few appointments for a hyperope who only occasionally wears glasses and refuses dilation). It looks like her contacts prescription is gonna be

L +2,0 -0,75 150

R +2,75 -1,25 60

The sphere may go up by another 0,25. She's getting fitted for toric lenses as she obviously couldn't tell her ecp of GOC.

She wants to go for different glasses prescriptions for different occasions, not too high as friends and coworkers would notice. Let's say -3, -4.5 and -6 range.

Am I right aiming for (-3 range):

Contacts

+5,00 both eyes

Glasses

L -3,25 -0,75 150

R -2,50 -1,25 60

She is 28, and can easyly accommodate 3 diopters. She already has a variety of low to moderate minus glasses based on her old astigmatism values.

Happy to hear your thoughts.

Hi,

I recently got a prescription for glasses

OD -0.25 -0.50x005 and os -0.25. Do you think id be able to get contacts with this, or would i need to make up a story and what could i say?


Cactus Jack 30 Jan 2017, 12:03

Sparky,

I suggest getting some +12.00 Contact Lenses. With them, your uncorrected Sphere "eye power" at your Corneas would be:

OD Right Eye +8.75

OS Left Eye +8.25

Assuming a Vertex Distance of 12 mm, your calculated glasses prescription would be:

OD Right Eye -10.00, -0.25 x 30 Add +1.25

OS Left Eye -9.25, -0.25 x 30 Add +1.25

Please remember that there is no guarantee of accuracy. You might want to consider ordering some very low cost, single vision glasses, from an online retailer such as Zenni, with NO options, If your distance vision with this combo is satisfactory, then order some bifocals or progressives with the frames and options you desire. It may be necessary to adjust the Sphere prescription in each eye slightly (+/- 0.25), but you may get lucky.

I've recently ordered 4 pairs of glasses, in 2 separate orders.

Had no issues with shipping and customs, there was even a customs check registered on the tracking.


sparky 30 Jan 2017, 07:30

Crystal Veil,

I think we should be safe for now in Europe. I am currently wearing my new -19.50 D combination which I just picked up two days ago. If anything I was having the impression that it took less time for the Zenni glasses to arrive than last time I ordered from them.

Shuron still makes the same old frames in the USA which is great for those of us who like vintage frames:

I think it depends whether this new approach is EU-wide or just UK customs. My guess (I do not know) would be that it is just UK customs acting alone. It would be typical of our current awful government which claims to govern 'for the many, not the few' to do just the opposite and protect the interests of big business.

If it was a new EU-wide policy might we not have heard about it?

Anyway, I hope you don't have problem with your delivery and look forward to seeing the results of your next shoot in due course.

gwgs,

this is alarming news indeed. It makes me wonder if my latest order from Zenni (Jan. 11th) will arrive in time for the purpose I had in mind. They always send a message within a couple of days that the glasses are ready and sent on the post. So far, no such message. I live in the Netherlands and perhaps they start to apply the same policy on my country as well. It would be a blow to my photography project if the supply would come to a halt.
