Hello everyone,

I recently bought the EyeQue miniscope that has been introduced here some time ago.

It appears to work well, at least for me. Doing the test bareeyed I came out with +/- 0 both eyes and after putting some +3.50 contact lenses in it showed -3.75 both eyes with no astigmatism. So there seems to be some precision in the measurement.

My girlfriend (natural hyperope) though was determined well underneath her most recent ECP prescription but with the correct sphere difference between her eyes. Her astigmatism was correct and just a few degrees off.

That led me to thinking that her accommodation at age 29 is confusing the results. This again got me thinking about overcorrecting her with contacts (making her myopic) and have her doo the test again. The difference between her resulting prescription and the sphere of the contacts should result in a more accurate real prescription.

Does that make sense?

Your question is a very interesting one. It's true in many cases -.50 glasses can be considered as "beginers glasses" because you can end needing stronger and stronger glasses every year. But to be honest I think that only happens if your eyes are in the early stages of changing. So its very possible that you could have skipped getting glasses and gone for the next 2 years without glasses only to be tested and given a -1.00 or stronger prescription later on. I can tell you that just because you are given a -.50 prescription doesn't always mean that your eyesight is going to worsen. My best friend's wife about 4 years ago was complaining about her difficulty with seeing when driving at night. At my suggestion she went for an eye exam and see told the optometrist about her issues with driving at night. She passed the vision test without any problem and had no problem seeing the 20/20 line. But at the end of her exam she was given a prescription for glasses.It read -.50 with glasses with AR coating. She was told to wear her glasses when driving at night and any other time she felt the need for her glasses. Since then she has been back several times to get her eyes checked and she still has perfect vision without glasses. But she always wears her glasses when she drives at night. So wearing glasses hasn't had any effect on her eyesight as far as making it worse.

Your co worker probably got her first glasses just as her eyes were beginning to change which is very normal. So even if she hadn't gotten glasses when she did her eyes were still going to slowly continue to worsen each year. I bet by now her eyes have reached the stable point and she doesn't still get yearly increases. She may may get new glasses every year or so just to stay stylish but I doubt that her prescription has changed recently. Same way as your wife. You didn't say what your age or your wife's ages are but when did your wife get her last increase? Do you remember how old your wife was when she got her first -1.00 glasses? If she was under twenty then she probably had smal increases each year of about -.50 which is about normal and her eyes should be near or at the point where she shouldn't need anymore increases in her glasses.

My wife dragged me with her to her eye exam, because she had also booked one for me. I had my first exam in years. The Dr said I am borderline for distance and after a short discussion suggested I get some glasses for distance and try them. Said if I wear them for a while then I can decide if I should continue wearing them or just come back in two years for another exam. I got them and wore them to work. One of my co-workers was surprised to see me wearing them, and I told her what the Dr said. She says there is no such thing as "trying" glasses. She says that once you start wearing them and get used to them you get hooked, and NEED to wear all the time. After she got hers, they were made stronger at each exam. I have never seen her not wearing. These are only -.50 in each eye. Not sure what I should do. Distance letters are clearer at night, not so much better during the day. (Wife started at about -1.00 and is now -2.75 and wears all the time.)

One more suggestion:

When you go for an eye exam, make a list of ALL your symptoms and concerns and take them with you. It will help your ECP understand your concerns and give him/her some clues what to look for.

Remember, your ECP can do what is called the Objective part of the the exam using their instruments. However, is another part of the exam, called the Subjective part. There is no way for them to experience what you are actually seeing. You have to tell them your symptoms and what you SEE. I think "How to Study . . . " will help you with that part.

Not that you need this information, but if you live near London, Moorfields is one of the best eye hospitals in the world.

I have some more questions, but I don't want you to think that I am an Eye Care Professional (ECP). My background is Electronic Engineering and Computers. I am 80 now and have been dealing with eye problems since childhood. I live in Houston, Texas. I became very interested in Vision when I could not get satisfactory answers from my ECPs. I learned the principles of Optics in Physics.

One of the things I have learned over the years, is to investigate any health things that don't seem quite right, without delay. The key is to detect health conditions in their early stages when they are most easily managed. Curiously, a very thorough eye exam often finds other problems such as high blood pressure or even diabetes in their earliest stages. The reason is that the eyes are windows into the body and a dilated exam allows the ECP to see the Retina very clearly to check for problems.

I am concerned about the sensitivity to light and the halos or "cloud" around lights at night. That could be something as easily fixed as a vitamin deficiency or the early symptoms of glaucoma (excessive pressure inside the eyeball) or even Cataracts. More about that later.

I am NOT concerned about your glasses helping more at night. That is normal. The explanation of that gets back to the principles of Optics. I mentioned that the eyes are biological cameras and there are lots of similarities to high end cameras. Both have the ability to control the amount of light that reaches the Retina or Film. In a camera it is called the Iris, in the eye it is the pupil. The opening of the Iris in dim light condition and closing down of the Iris has a secondary effect that photographers call "Depth of Field" or range of useful focus. Then the Iris is closed down in bright light, every thing in the picture over a broad range of distances will be in good focus. In dim light, the Iris is opened wide and the range of focus in the picture will be very narrow. The same thing happens in your eyes. You can experience the same thing by looking through a button hole.

The problems at intermediate distances could be related to the early manifesting of the symptoms of Presbyopia. The idea that a person does not need focusing help until their 40 is a Myth. Presbyopia, itself, is caused by the gradual stiffening of the protein that makes up your Crystalline Lenses. It actually starts in childhood but typically does not become a nuisance until the late 30s or early 40s. A secondary cause of the symptoms of Presbyopia is weakness in the Ciliary Muscles. The Ciliary Muscles and the Crystalline Lenses are the Active part of your Auto-Focus system. For their size (very tiny) the Ciliary Muscles are the strongest muscles in the body, their job is to squeeze the Crystalline Lenses to increase their PLUS power for focusing close. I they become weak or out of condition from not being used much they have trouble squeezing the Crystalline Lenses. That is what happened to me. I mentioned earlier that my first prescription was -1.50 in one eye and 0.00 in the other. Needing a low MINUS prescription is like having built in reading glasses. I was reading with the -1.50 eye and using the 0.00 eye for distance. My eyes did not work as a team. There were other symptoms, but in the 1940s and 50s, no one "connected the dots" and I did not know any better. The most predominant symptom was that I could not play ball sports, Baseball here and perhaps Cricket there. I had very poor depth perception and by the time is figured out where the ball was, it was in the catcher's mitt. Because my eyes did not work well together, I wound up needing bifocals when I was about 20 and trifocals in my 30s to function comfortably.

I am a little concerned about seeing double, but it could be related to focusing difficulties. There is an interconnection in your brain between the Focus Control System and the Eye Position Control System. The interconnection causes your eyes to automatically converge when you try to focus close. Sometimes the convergence signal is too strong or too weak and you see double. That can often be fixed with some close focusing help or perhaps some Prism correction in your glasses.

The halos and clouding could be a symptom of Cataracts. There are several types of Cataracts, but he most common one is clouding of the Crystalline Lenses (mentioned above). It can happen at any age, including being born with Cataracts.

Years ago, surgery for Cataracts was extremely serious and required long recovery and wearing very high PLUS glasses. Today, as a result of discoveries made in the UK after World War II, Cataract surgery is very safe and is typically done on an Outpatient basis. The discovery was that some pilots had had slivers of the Perspex (acrylic plastic) in their eyes for years after WW II, without any problems.

That discovery meant that the clouded Crystalline Lens could be removed and replaced with a plastic Intra Ocular Lens (IOL) and the high PLUS glasses would NOT be required.

I had Cataract surgery in both eyes in 2001. It was the nearest thing to a non-event I had experienced. Today it is even better, should that be the problem with the clouding. Naturally, I was pretty scared for the first surgery. It only took about 10 minutes for the actual surgery and the vision improvement was so dramatic that my first question was "when can we do the other eye". The doctor replied, 2 weeks. I still wear glasses when I need to see very well, better than 20/20 or 6/6, but I can actually function without them. I'll tell you more about that if it turns out to be the problem.

I suggest that you do a few things.

1. Get a pair of +1.00 or +1.25 Over-the-Counter reading glasses. They are not expensive. Wear them over your regular glasses for reading or using the computer and see if they help.

2. Read the piece I wroth on "How to Study for an Eye Exam". I have posted it several time on ES and also on the Vision and Spex site. If you are unable to find it, I will post it again.

3. Make an appointment for an exam by an Ophthalmologist. You need to find out what is going on as soon as you can. Please DO NOT avoid this. It is better to know than not know and early detection of problems pays BIG dividends.

4. Please let me know what you plan to do and the results of the exam.

5. Feel free to ask more questions.

Thanks, I am 30, UK, work in an office.

I googled "dilated" and no never.

Prescription says R sphre -1.00 cyl -0.25 and L sphre -0.25 cyl -0.50

Cactus Jack 10 Dec 2017, 00:58


Vision actually occurs in the brain. Your eyes are merely biological cameras. If there is a difference in the clarity of the images in any visual situation, your brain will select the best image and use that as its primary source.

I suspect you are using your -1 eye for reading and your other eye for distance. I know how that works from personal experience. When it was discovered that I needed glasses, my prescription was -1.50 with Astigmatism in my Left Eye and Plano (0.00) in my right.

The results of that was that I would get severe headaches when I read very long with my glasses. I really needed bifocals, but because of my age (20), it was hard to find an optometrist that would prescribe them.

May I asl a few questions?

1. Your age?

2. Your complete prescription?

3. Your occupation?

4. Have you ever had a dilated exam by and Ophthalmologist?

5. Where do you live? (Country)

Hi, just found this site on Google and I have a question. No eye problems before now except -1 in one eye and glasses help with night time driving but other than that I can see fine (just blurry when only looking out one eye).

However, in last year I have started losing focus when reading. Things go double involuntary. Its like im crosding my eyes. Vision is not blurry up close but i just lose control involuntary.

At a middle distance I get terrible strains, tears or burning. One person wearing a stripy shirt completely messed with me, I can't describe how hard it was to focus on him.

My other problem is glare off lights, headlights and street lamps. This is a "halo" according to Google but its more like a cloud? Glasses at night make it worse but I really can't see road signs then without them. Some lights burn abd give me a headache.

I am going to an optician, but what could be going on? Its like my eyes can't focus and are also light averse but the vision is much the same

I was just at a local sports bar and I was chatting with a server that got her first glasses from me back in July. She was telling me about falling asleep wearing them and waking up without them and she was scared she would find them broken. But she was happy to find that they were fine. But she wants me to order her another pair just in case something were to happen to her glasses. She wears her glasses full time even though her prescription really isn't very strong. But that made me think about you and your girlfriend. We last chatted in Sept. and apparently your girlfriends glasses were still providing her with perfect or near perfect vision if she was able to see the hockey puck so well. Something i'm sure she wasn't able to do before she got glasses. But she has had her glasses for around 7 months now and considering what her prescription was for her first glasses she really should be needing an increase in her prescription anytime now. In fact I honestly thought she would be needing an increase at around 6 months. Have you noticed her having any problems with seeing anything recently? I think you and her sister won't need increases until around the 12 month point which would be around early June.

What else is happening with you and other things? I'm still hoping the Cardinals can work out a deal to get Stanton from the Marlins.

Weirdeyes 04 Dec 2017, 23:36

Has anyone else here done a DNA test? I did one and I tried this app that predicted my glasses prescription based on my DNA results. It guessed that I'm around -2.75. That's kind of close to my dad's prescription, but nowehere near mine. I do think my current prescription does average out to close to +2.75 though.

Hi again

Re. My post of 20 Nov 2017, 05:34, I've realised that I've ascertained what is going on myself via constructing my post on the Hyperopia and Presbyopia Progression thread regarding Carrie's friend Danielle.

I'll be 44 next month, and I don't yet have a reading add. I feel that my close up vision is starting to go a bit, but that my ciliary muscle is still sufficiently strong for me to accommodate over this, and what is happening is that on days when I do a lot of close work, my ciliary muscle is working hard, causing the burning I feel, then not fully relaxing later in the day.

I had this issue before I started wearing my distance prescription full-time owing to a lot of eye burning and eye strain, and it has now resolved on days that I don't do a lot of close work. I suppose that wearing my distance prescription full-time is preventing the eye strain that causes this issue, but that since my close vision is starting to go, that I am still experiencing eye strain even with my distance prescription, on days that I am doing a lot of close work.

Since I had the option of only a 0.25 add last time and I am not due an eye test until June 2019, I've decided to further enlarge the text on my lap top and smart phone and try to increase the viewing distance for now, to see whether this helps.

All the best


Cactus Jack 21 Nov 2017, 07:59


What you described It is common for people who have had Lasik to correct long existing nearsightedness (Myopia), farsightedness (Hyperopia), or uncorrected mild Hyperopia as they get older. Come to think of it, It can also happen to people who never had any type of refractive surgery and those with perfect vision.

There are two culprits at work, Presbyopia and Pseudo Myopia/Latent Hyperopia.

How these two things work to cause what you described has been explained many times on this and on the Vision and Spex web site. I suggest you look back on this thread and others for a full explanation.


Weirdeyes 21 Nov 2017, 04:14

Is it normal to NOT notice an image size difference when I wear my glasses which have a 3D difference? I actually notice things look smaller through my left eye when I wear contacts.

@Ross 20 Nov 2017, 21:03

Hello, I'd like some help in understanding what could have happened to the eyes of someone who has had laser vision correction in the past.

My wife and I were visiting my older sister and her family. I hadn't seen her for over a year, and I must say I was surprised to see her wearing glasses again, apparently full time. I could tell that her eyes were now slightly magnified, indicating she is farsighted.

She's 46 and had the surgery probably around 1999 or 2000. I'm ten years younger so my recollection is vague and quite limited. I do know she was nearsighted enough to need full-time correction and frequently complained about her contacts bothering her.

As we entered their home my wife quickly commented on her glasses and raved about her frame choice. My sister thanked her and explained that she had had reading glasses but now needed correction for distance as well, that she was having headaches, etc. She left out the surgery part. I didn't see the need to press the topic, particularly in front of her family.

True, she's had reading glasses for a few years, I think; I've seen her wearing them a few times while we were visiting one another. I didn't think much of it, though, because by then she was in her early 40s and was always an avid reader. It was a given that the surgery would not forestall presbyopia.

I am however confused as to how she could have developed the need for distance correction, and that, too, farsightedness. Any ideas?


Lou 20 Nov 2017, 05:34


I just thought I'd share a gripe of mine. During the summer, I was having two issues with my right eye/right eye prescription. The first was eye strain and burning without my glasses, the second was my right eye prescription sometimes seeming too strong, especially if worn for the first time later in the evening. Wearing my glasses full-time has largely solved both issues, but I have had a re-occurrence of my right eye prescription becoming too strong in the evening, probably owing to tiredness.

What basically happens is that after wearing my glasses all day without any issues, I've been sitting down to watch telly pretty late in the evening, admittedly with my eyes feeling very tired, owing to having done a lot of close work during the day for the past couple of weeks, only for the digital clock on my telly to look slightly blurred. When I cover each eye, I see that it is the right eye which is blurred. Without my glasses, my right eye is still blurred, but blurred differently. I've found that when this happens, that if I turn my glasses upside down (My prescription is R: +0.50 Sph -0.50 Cyl Axis 92, L: +0.25 Sph -0.25 Cyl Axis 85) and look through my +0.25 Sph -0.25 Cyl left lens with my right eye (which works since my axis is around 90 with each eye), it comes into focus.

Since I was worried that my right eye prescription could have changed since June, on two separate days, I have tested my vision during the day with a snellen chart pdf (following the instructions carefully). On both occasions, I found that my right eye was perfectly clear with my +0.50 Sph -0.50 Cyl Axis 92 prescription, and that when I tried my glasses on upside down, I saw a reduced same direction version blur of my vision without glasses, or to put it more simply, with the snellen chart, my right eye is blurred without my glasses, perfectly clear with my glasses, and probably as can be expected, with my glasses on upside down, is half way between no glasses and glasses. I'm therefore sure that my right eye prescription is overall correct.

I have a very good optician, who I trust, and I changed my

glasses owing to a small change in my left eye (my right eye stayed the same) prescription in February 2017. I visited her in June regarding this issue, scheduling my appointment for as late in the day as possible, and both my subjective findings and her objective retinoscopy both found +0.50 Sph -0.50 Cyl to be right for my right eye.

I've confirmed the same thing twice at home during the last week.

Why oh why then does my prescription reduce in this eye when I am very tired later in the day, so that I can then see better with +0.25 Sph -0.25 Cyl?

Which part reduces to 0.25, the sphere, the cylinder or both?

This post (see below)from another thread (I hope the poster won't mind me re-posting it here) also mentions needing less plus later in the day.

Do we all need slightly less plus/slightly more minus later in the day?

All the best


Mike 08 Nov 2017, 07:39


I find this Red Green chart to be easy to tell if you need more or less + or - Just need to open it on a big enough screen that you can view from 10 feet away or more.

I messed around with a few pairs of old glasses, and I could tell the difference right away. With +0.5 the green was a little sharper, with +1.0 they are the same in the morning and the red is a little sharper when I tested at the end of the day.

SoCal 10 Nov 2017, 11:25


You're right, no contacts for me until I find out what this is all about. It's not terribly bothersome but it definitely is something to take a look at. I could see now how something like that could be masked by wearing contacts so much (from morning to night and sometimes morning to morning . . . eek). So glasses it is until further notice will be something I will have to adjust to. Thankfully I've been able to fix my favorite pair that my children so lovingly decided to bend so as to test their craftsmanship. I wonder what the annual exam will turn up. As long as it's not a decrease in rx I will be happy. I love where I am at right now but a little more sharpness won't hurt anyone. I love that HD feeling!

Soundmanpt 10 Nov 2017, 10:24


It wouldn't heal if you have been wearing contacts lenses for those past 6 months. In fact that would only irritate it more. Also as you probably know with your contacts on your eyes don't as much oxygen as they should so that would also not help with the healing process. But i'm glad that you're going to get it checked out. One thing I am quite certain of is that you won't be be wearing contacts for a while.

SoCal 09 Nov 2017, 15:53

I don't think it's any sort of abrasion, since the discomfort has been around for about 6 months. Surely something like that would have healed by now. I don't have any other symptoms, such as redness or tearing, only a dull ache and intermittent itching when the lens or cold air come into contact with my eye. I would think that an abrasion or an infection would present with other symptoms. I guess we shall all find out on Monday.

Thank you all for your quick responses!!

NNVisitor 09 Nov 2017, 15:41


A corneal abrasion (scratched cornea) could have been caused while inserting the contact lens. It hurts especially when subsequently inserting a contact lens during subsequent days. These are warning signs. The major concern is such an abrasion getting infected. That is a serious issue which is potentially sight threatening.

Soundmanpt 09 Nov 2017, 15:06


I betting you have a scratched cornea. Probably some meds and time will take care of the problem but you will be wearing glasses for a while until it completely heals.

SoCal 09 Nov 2017, 14:01

-Cactus Jack

Just made an appointment for this coming Monday. I suppose I shall find out soon enough what the mystery eye problem is. I guess this has been the cause of some minor headaches. I just hope it's something that can be fixed quickly. In the meantime, it's spec, specs, specs!

Cactus Jack 09 Nov 2017, 10:41


See your ECP as soon as you can. Something has made that Cornea more sensitive than is normal. Possibly some kind of infection, though dry eye is possible. Another possibility is that you have inadvertently scratched your Cornea.

There is nothing to be gained by delay. It will probably not bet better on its own.

Please let us know what your ECP says is the cause.


SoCal 09 Nov 2017, 09:29

So, this has been an ongoing problem for the past 6 months or so. I wear contacts a lot, like more than any one person should wear non extended wear contacts. About 6 months ago, I was putting in my right lens and I felt something that I have never felt before. It happens every time I put the lens in without fail. The only thing I can equate the sensation to is a sensitive tooth. You know when you have a sensitive tooth and you eat something too cold or too warm, you get this instant ache in your tooth and the surrounding area. Well that same feeling happens when I put in my right lens. There is this dull ache when the lens goes in and then it kind of disappears. I don't know if this is something I should be concerned about or not. I also did notice that cold air makes my eye have the same sensation. It's like my eye has become sensitive to cold things. Is this making any sense? I'm wondering if it is just a dry eye, something that will go away on its own or maybe something that will eventually lead to something slightly more serious. I have consulted google and haven't turned up many results. Thanks!!

minus5wholuvsgwgs 09 Nov 2017, 00:49

My GF is a glasses wearer and has never gone for contacts thank goodness She has just 0.25 astigmatism interestingly when she first got glasses aged 7 she was able to go bare eyed so presumably a low prescription

NNVisitor 08 Nov 2017, 19:56

Re:Vertex distance

Re:Contact lenses vs. glasses

I remember an opthalmologist telling me to press as close as I could right against the lens he was showing me in order to read the letters he was showing me. With high myopia the vertex distance is very important. With eyeglasses for high myopia the images are smaller and the best possible vision is obtained when looking through the center of the lens. By habit many of us will look left, right, up, down and with strong minus glasses what we see is no longer so clear as by looking only through the center of the lens. With contact lenses the minification for me was gone. Everything looked natural without the distortion that strong glasses create and I have great peripheral vision. Of course some people have problems with, can't wear or don't want to wear contact lenses. For these people who wear glasses only their best vision is what they see wearing their glasses. Depending on their situation it may be very good or not so good.

Cactus Jack 08 Nov 2017, 07:53


Visual Acuity (VA) depends on many factors. The obvious one is the accuracy of the corrective prescription and its completeness. Cylinder and Axis correction for Astigmatism can be very important, if not completely corrected, along with the Sphere correction.

The non-obvious factor in VA, when correcting HIGH Myopia with glasses, is Vertex Distance (VD) effect. In your GF's case, minification of the image on the Retina. A "normal" Human Retina, typically has about 120 million Rods and Cones, which are similar to Pixels in a digital camera. That is a huge number, but there are only about 1 million fibers in the optic nerve. That means that the signals from those 120 Rods and Cones need to be compressed on to those 1 million nerve fibers. If the image (picture) elements are extremely minified by VD effects, some of the image detail (very small text) may get lost in the compression process. Same thing happens in your digital camera if the image sensor does not have enough pixels and 4K TV shows better detail than 1080 P HD TV which is better than Analog TV which is only about 450 lines.

One solution, if she can wear them, is contact lenses. They have 0 VD and only a little bit of image minification. If she has Retinal problems, she may not be able be fully corrected.

BTW, VD effects are the mathematical SQUARE of the glasses prescription. VD effects for -5.00 glasses are small which is why Contacts for -5.00 glasses are about -4.75 and contacts for -16.00 glasses would be about -13.00.


minus5wholuvsgwgs 08 Nov 2017, 06:10

my high minus GF -16.25 and -15.00 with a reading add of 1.5 I noticed cannot read signs too well Apparently she was not prescribed full distance correction apparently if they did she would need a separate reading pair Odd because she wears varifocals does anyone have any suggestions why this might be ? She does not drive

NNVisitor 30 Oct 2017, 17:38


People go into debt to get Lasik. Not something I would ever do even if I was able to get it. I don't want a laser to permanently change my cornea. I'd still probably need reading glasses after Lasik so I may as well wear contacts or glasses as I do now. Plus the money I won't spend on the procedures I can spend on other things.

Nat 29 Oct 2017, 15:52

I dont to have lasik have never thought about it until they asked. I have no problem wearing glasses or contacts. I read that nearly half the population is nearsighted so it's normal. All I asked was is it common for people to get lasik in America? Or is it for rich people that don't want to be seen wearing glasses. So you think they will get nearsighted again? If you need glasses then would need to wear them all the time anyway how much prescription you have

Soundmanpt 29 Oct 2017, 12:46


If those young ladies were around 27 years of age then most likely their eyes had become stable so at -5.00 and -4.00 is about perfect for having lasik. They both had probably ore glasses from when they were pretty young so they were tired of wearing glasses. So who knows how long they will be able to go until they need glasses again. But even if it is only 4 or 5 years they should be happy with the break they had from wearing glasses and most likely their eyesight won't get anywhere near as bad as it was before. So wearing much weaker glasses won't be so bad by then.

NNVisitor 28 Oct 2017, 10:39


You are happy wearing glasses and your myopia has increased while in your twenties. It may still increase. With Lasik there are risks and the cost. The risks are that you may still require glasses and have to pay the full cost for the surgeries. The Lasik surgery will change the shapes of your corneas permanently possibly to the extent that you will not be able to wear properly fitted contact lenses should you want to in the future. As a person who is happy wearing glasses I see no need to get Lasik.

Weirdeyes 28 Oct 2017, 09:00


I think I'll wait until my prescription feels more stable and comfortable. My mom got lasik for farsightedness, but she's still wearing glasses and getting fluctuating vision. I really hate fluctuating vision. I know it's partially due to presbyopia and latent hyperopia, but I think it's also regression. Her glasses were around +4.00, but they determined she's actually closer to +5.00.

I'm 28 and been wearing glasses about 10 years all the time as I'm shortsighted -5.00. They were both 27 one of them was also near -5.00 and the other -4.00. Is if common for people to get lasik there? I dont want the operation is ok with glasses and contacts. My optician has never said about lasik is normal to wear glasses and lenses here

I think it's good to be skeptical. Perhaps the most important question is whether you perceive any problems being farsighted and having to wear glasses? If you are happy with your vision wearing glasses as you are, perhaps there is no real need to undergo surgery.

Most likely they would only do your left eye. I don't believe, but I am not sure if your right eye is considered bad enough for them to work with. But maybe because of your astigmatism they might be able to do that eye as well. I think they would be able to correct your left eye to at least 20/20 if not slightly better. Most doctor do an evaluation at no charge if your thinking about getting it done. Remember if you only get your left eye done the cost will only be half as much. You may be better off going that way and just wearing weak glasses to correct your right eye.

Speaking of lasik my parents think I should get lasik. I'm pretty skeptical about it. I don't even know how it would work. Will they only do lasik on my left eye or will both my eyes get it done? If only my left eye gets lasik how often will I wear glasses? My current prescription is R +0.75 -0.75 L +4.25 -1.50. I'm pretty sure I have quite a bit of latent hyperopia as well. I wouldn't be surprised if they say my left eye is around +5.00 and too bad for lasik.

Just curious when you say "girls" do you mean young girls say under 20 years old? I ask that because if the already have gotten lasik I wonder if their eyes really had become stable? Generally it is best to wait until your at least 20 years old and even better to wait until maybe closer to being 25 to get lasik. If these were teen girls chances are they will be back wearing glasses in then next year or so and I don't mean reading glasses. I mean they will be nearsighted again. Now depending where they had their lasik done they may have a warranty which would allow them to come back in and have a "touch-up" done which means having lasik done again as long as their corneas are still thick enough. But they will have to wait for their eyes to get to at least -1.50 before they can have a touch up done. Until then they will be wearing glasses. If their eyes don't get as bad as -1.50 they will be wearing glasses from then on. You're probably the smarter one by continuing to wear your glasses at least for now anyway. Later on after your eyes have completely stopped changing then if you want lasik you're likely to have better and longer lasting results.

I was talking to some American girls I made friends with while on holiday and they both have had lasik and was surprised I wasn't interested in getting it done. Is it really that popular to get lasik in America? I don't have a problem wearing glasses and I can always wear contacts. I don't want to pay for a operation and need reading glasses after

You have mentioned about Danielle going in twice recently to get her eyes checked. I'm a bit surprised that Vickie didn't want to go along to get her eyes checked as well. She has had her current glasses for well over a year now and knowing how much she enjoys wearing her glasses I would think she would be hoping to get an increase as well as new glasses by now. Next time a glasses conversation comes up with Danielle and Vickie is around you should ask Vickie when she is due to get her eyes checked again.

Everyone is different, so it is possible. She could also have some allergies to things such as pollen and glasses may help minimize how many allergens get in her eyes. No way to really tell the cause of the bloodshot eyes without a complete examination and tests.


JC 19 Oct 2017, 07:53

Has anyone heard of red bloodshot eyes simply from not wearing needed glasses? I saw a video of a nearsighted girl who didn't wear glasses for about 15 minutes. I noticed red eyes and she said that happens when she doesn't wear glasses for chunks of time. I'd estimate her prescription in the -6 to -8 range, and she also mentioned astigmatism. She never wears contacts. My only guess is eyestrain from the astigmatism -- I'm nearsighted and have gone much longer stretches then that and never get red eyes from it.

I don't have enough information or knowledge to make any more suggestions. There is no way I can experience what you are seeing. My suggestion is to try to write down what you had been doing for 10 to 15 minutes prior to the event and collect enough data to see if there is anything in common that leads up to the event. Also, try to discover if there is anything that seems to cause your vision to go back to normal.

Discovering the source of a problem is like being a detective. You have to look for clues that may lead you to solving the problem.

Good Luck!

The old glasses thing has never been mentioned. Also no subject really involves close work, I just do homeowrk at a usual distance. I am not much of a reader.

Cactus Jack 13 Oct 2017, 14:49


You are right. It is weird. The only things in your vision system that can change rapidly are your Ciliary Muscles and Crystalline Lenses. They are the optically active part of your Eye's Lens system that allows you to focus, similar to the auto-focus system on a camera.

There are two types of Myopia. Axial or True Myopia, which is caused by a mismatch between the total optical power of your eye's lens system and the length of your eyeballs The other type is Pseudo or False Myopia, which is caused by the Ciliary Muscles having difficulty fully relaxing for distance. Both types can be present and their effects add together. It is the Ciliary Muscles and Crystalline Lenses that compensate for Minus over correction that is the first step in Inducing Myopia.

The reason I asked about dilation is that one of the effects the dilating agent has is to temporarily paralyze your Ciliary Muscles so they cannot affect the results during an exam. However, the agents that are typically used are not very strong so they will wear off in just a few hours. If a person has been wearing much more minus than that need for full correction, the dilating agent may not have time to fully relax the Ciliary Muscles.

Where I am going with this is that if your Ciliary Muscles are under constant stress they can occasionally spasm or involuntarily relax. That might cause an effect similar to a zoom lens on a camera.

You mentioned that you were 18. I assume that you are in school and likely do a lot of studying and close work. Has your ECP ever suggested that you use an older, weaker pair of glasses for close work or any form of reading glasses to reduce your focusing stress? May I ask the subjects that involve a lot of close work?


WeirdVision 13 Oct 2017, 09:29

I live in America, and yes I have a had a dialated exam. I am not sure what my first prescription was at all. Sorry.

Cactus Jack 12 Oct 2017, 21:29


I keep thinking of questions.

You said that you started wearing glasses 4 or 5 years ago, to you remember what your first prescription was? Exact would be nice, but close would be helpful.

BTW, You need to understand that I am not an Eye Care Professional (ECP). I am an Amateur in the original sense of one who studies a subject out of love. In my case it was somewhat out of necessity. My background is Electronic and Computer Engineering (IOW "Problem Solving"). I just turned 80 and have been dealing with vision problems since my early teens. I was not satisfied with the answers ECPs gave me to explain my vision problem and I started studying about it.

These days, the word Amateur has a bad connotation. Many of the scientific principles we use today, were discovered by "Amateurs" such as Sir Isaac Newton, Voltaire, etc. I am far from being in that class, but I have earned a reputation as being a pretty good explainer.
