How Do I Know if my Glasses Prescription is Wrong?

Okay, so you have that nagging feeling that something isn’t quite right with your new glasses. Your vision isn’t as clear as it should be, or things are appearing fuzzy and indistinct. You may be experiencing a sense of tunnel vision. Perhaps your depth perception is just a little bit off.

Is Your Glasses Prescription Wrong?

How Do I Know if My Glasses Prescription is Wrong?You know from experience or you’ve been told by your optometrist that some prescriptions, especially bifocals or trifocals, require an adjustment period during which you need to get used to the changes of a new prescription. This transition period can last (depending on the prescription and the individual) for days, weeks, even upwards of a month. So how can you tell if your vision inconstancies are related to this adjustment period or are instead a result of an incorrect prescription?

The answer typically lies in the symptoms you experience and their severity.

Errors made during an eye exam are not unusual. They can result from a typo on a computerized report or, more commonly, a misreading of a handwritten prescription. The misinterpretation of a single digit – or the omission of one – can wildly alter a prescription. Sometimes incorrect measurement readings are to blame and these are not always the fault of the optometrist. Perhaps, without realizing it, you’d scheduled your exam late in the day, maybe after work, and your eyes were tired and weak, skewing your results.

If your symptoms include the following, you may want to return to the optometrist for advice or at least a confirmation that no clerical error in your prescription was made:

  • Extreme blurriness or lack of focus.
  • Poor vision in only one eye when the other is closed.
  • Headaches or dizziness caused by excessive eye strain.
  • Extreme vertigo or nausea not related to any underlying medical condition.
  • Problems persist despite the fact that the lenses are properly centered in front of your eyes.
  • Problems persist despite waiting out the recommended adjustment period.

It’s true, however, that if your prescription has changed or you’ve switched to bifocal, trifocal, or progressive lenses, your eyes do need to adjust – particularly if the prescription strength in only one eye has changed. If your symptoms most closely follow the ones below, your problem may simply be caused by the change in prescription:

  • The blurriness or fuzziness you experience improves with time.
  • You haven’t been using your new glasses on a regular basis.
  • Headaches, dizziness, nausea, or vertigo lessen the longer you wear your glasses, or subside greatly after the first few days.
  • Vision is clear when each eye is isolated.
  • You haven’t yet completed the transition period suggested by your optometrist.

Shop Prescription Eyeglasses

Realize that you know yourself better than anyone else. You know how your eyes react to typical daily eye strain and what they feel like when you’re tired. If you can rule out these conditions, and you’ve been patient with any change in corrective lenses and given your symptoms the prerequisite amount of time to clear up, the fault may lie in your glasses and not in yourself. If you have any cause to suspect this is the case, a follow-up visit to your optometrist is certainly warranted and definitely recommended.

    Hi my name is Julia and I just got my glasses friday and put them on first thing in the morning on saturday. My prescription did change my right eye is worse than my left eye. When wearing them around the house things that appear to be far away like a digital clock are blurry and cannot read the numbers. I read online that it could take a couple of days to adjust called the adjustment period but could it also be wrong prescription? How long should i wait to go back to the eye doctors and wait for the adjustment period to take?

      Hi Julia,

      It is true that there is generally an adjustment period for new eyewear, especially if your prescription has changed significantly. It shouldn’t take more than a week to adjust. If it does, or if it doesn’t appear to be getting any better after a few days of wearing, it’s a good idea to make an appointment to see your eye doctor and have the prescription checked out. It’s definitely possible that the eye doctor made a mistake, and the lab could have made a mistake as well.

      Please let us know if you have more questions, and let us know how it worked out!

    Hi my name is Jade, I’ve wearing glasses for just over two years and at my last eye test I was told that I was not short sighted (which is the prescription I had been wearing) and I have been given reading glasses. I then started my driving lessons and I couldn’t see the licence plate of the car in front of me, my driving instructor warned me that if I can’t see it I will fail my test. So have I been given the wrong prescription? And is it possible for my eye sight to change like that in two years? Thank you.

      Hi Jade,

      It’s definitely possible that your eye doctor gave you the wrong prescription; it happens more often than you’d think. I’d suggest going back and explaining your problems to the eye doctor. It also is possible for your prescription to change that much, though it’s rare. See what your eye doctor has to say; I think it was a mistake on their end, or on the end of the glasses lab.

    Hey I got a higher prescription than usual,I guess the optician messed it up.I got used to it but after a while my eyes started to develop fine lines and they look hollow too.I’ve requested for new glasses but is the hollowness and fine lines really from the wrong prescription and how can I get rid of them?. (Ps: I don’t wear them as much as I should and I’m only 18 so I think its too early to have finelines and hollow eyes)

    • Kieran Hunt
      March 4, 2014 | 3:38 am

      Hi Teni,

      I’m not sure what the fine lines you’re experiencing could be. Are you sure there isn’t a scratch on the lenses of the eyewear? If you are experiencing abrupt changes in your vision and the appearance of your actual eyes, it’s a good idea to see a doctor as soon as possible just in case there is something more than simple corrective vision problems at work. Otherwise, I think it’s probably due to the different prescription in your glasses. Also, if you don’t need very strong corrective lenses, you may want to consider going with contacts if you don’t like wearing glasses.

    hi. i have chronic daily headaches/migraines.eye strain and sensitivity seem to happen on a dime. ive had trouble finding an eye doctor, even a nuero optomologist (he was very brief and seemed over booked) wasnt very helpful. i could tell my right eye had gotten was hard to tell with the left because my eyes always have some pain/strain going on.when i got an eye exam, the 24/7 migraine was getting worse about the time of my appointment. it led to a long grueling anxiety filled appointment. this first appointment was with a regular optomologist. with the exam,i couldnt decide on the right eye, nothing looked clear. i remember making a decision quickly on the left, it SEEMED very clear.according to the new prescription, the left eye had previously been over corrected. just a hair, but for me, a hair is…a horse tail of a difference lol.. i got new glasses today. felt a tiny twinge in left eye. im ignoring it, and i know the migraine i have now is not only because i dont have fl-41 orangish tint on that WILL go on as soon as i know glasses are correct, but no anti glare either so i think my eyes are freaking out a bit. ive had them on about 6 hours.

    i was told things would look blurry at first.
    my sister had reminded me prior to ordering the glasses that if eyes are over corrected with glasses, things will look blurry..

    this was a 4 month process with insurance getting to see the right docs and organizing how to get 2 pairs, one tinted one not (hard to see at night with tint or in doors sometimes).. so this is distressing. wouldnt know who to go see because the nuero optomologist i saw and appointment which took 3.5 HOURS(im trying to understand what even happened, not even 10 minutes was with the doctor) wrote the prescription i had previoiusly gotten before seeing him 2 months prior. i was referred to the expert because the regular eye doc hadnt heard of the tint i use.. insurance only pays for one eye exam,unless referred somewhere else. do i see the nuero guy that should have given me an eye exam(and was going to, not sure what happened there) before copying the other docs numbers and signing his name?( i would ask this to insurance but ive gotten the run around between docs and insurance for months and wrong answers 24-7, and obviously i will have to ask eventually. this is all very subtle differences that eye docs surprisingly are that aware of..not the people i met anyway.

    mostly i just want to know if its possible for my left eye that supposedly was SLIGHTLY over corrected for a year, to hurt or feel strained, almost more than the right eye(which is where MORE correction was put in the new lenses).. does the brain or eyes do the same adjusting when glasses are over adjusted, or, how is it different? yes everything is blurry and disorienting, but the left eye seems worse. was i just used to STRAINING my eye to see through an over corrected lens so long and the correct prescription is confusing it?

    id ask the docs, and will have to, but, considering eyes are such a huge part of migraines, im so surprised of the LACK of knowledge eye docs seem to have about the importance of A- making sure the prescription is right, B- understanding things like TINTS and anti glare and suggesting it for debilitating light sensitivity which 99% of migrainers have.. made a world of difference for me!(even tho it sucks having orangish sun glasses looking frames, but, doesnt matter if it relieves some pain-also good for anyone who works on computers a lot, whether they need glasses or not.)any suggestion would be great! no idea what site this is that google led me to, but thank you! and i do have an astigmatism.. not sure how that would affect things.. would THOSE numbers have anything to do with how my left eye feels if the astigmatism numbers are off? (i dont know if there ARE numbers, but i think so?)

      Hi Marina,

      I’m so sorry about all the trouble you’ve been having! It sounds like a very stressful ordeal, and I sympathize. I’ve been there.

      Your problems sound like they could stem from sensitivity to wrong prescriptions. Though it could be neurological, and I do think it’s a good idea to follow up with the neuro, I also believe that you have what eye practitioners call non-adaptive sensitivity. Basically, if that’s the case, your eyes are more sensitive to slight imperfections in your corrective lenses compared to the average glasses wearer.

      Did you know that there is a tolerance held by labs across the world which says how “off” your prescription can be for it to still be considered correct? That’s because the vase majority of people can’t notice small imperfections in the strength of their corrective lenses. If you are more sensitive to these imperfections than the average person, than even a prescription that is “correct” may still give you problems.

      Your best bet is to follow up with the neuro, and go back to the eye doctor and say, plain and simple, that the prescription you received doesn’t work for you. Most eye doctors will remake your glasses for you free of charge if they made a mistake. Additionally, you should mention that you believe you are more sensitive to slight imperfections in the strength of your glasses, and request that the lab make the glasses to a stringent tolerance (no allowance for imperfections).

      Please know that you are not the only one who suffers these problems, and there are solutions. You just need to find the right combination of corrective lenses and tints. If your problem is also neurological, there are other steps that need to be taken, but hopefully you’ll have more luck with the neuro the next time you see him. When you’re there, if he tries to rush you out, let him know, in no uncertain terms, that you’re not okay with leaving without some kind of answers, or at least a plan. This seems to work with most doctors.

      The last thing I want to let you know is that this “tolerance” thing with corrective lenses being approved even if they’re imperfect is not because eye labs do hack jobs. Eye doctors write prescriptions to very specific powers, and the creation of corrective lenses is incredibly precise and painstaking. The technology today continues to improve, but it’s very, very difficult to achieve perfection every time. The guidelines outlines by the American National Standards Institute gives labs suitable tolerances to ensure that corrective lenses that are “good enough” that the average human eye can’t detect the difference.

      Please let us know how this worked out for you and if you have any more questions!

    Hi was wondering if you could help.

    I got new glasses and straight away i was unable to read and stay on a computer for anywhere near as long as i used too. As with my new glasses and new prescription came blurred vision after a few hours of reading.
    I have been back to my optician on numerous occasions and have gotten a second opinion else where to check my prescription but all seems to be well there. I have now reverted back to my old glasses after 8 months of trying my new ones.

    What else could be wrong or what could be checked to make sure i have what I need in my glasses?


    • Kieran Hunt
      March 12, 2014 | 4:01 am

      Hi Michael,

      I’m surprised that you have gotten the same results even with a second opinion. Are you sure that you don’t need a bifocal? It sounds like you need a separate reading prescription from your standard distance prescription.

      This is a problem that occasionally happens with people who switch to progressive bifocals after not having used them before. If you are wearing progressive bifocals for the first time in your new glasses, it’s possible that you just can’t adapt to progressives and you need a lined bifocal.

      Can you contact your doctor and ask if you need bifocals? Also, if your doctor says that you have progressives in the new glasses, as him/her if this is the first time s/he has ever prescribed progressives to you. Then you can get back to us and let us know what happened!

    I have just picked up my new glasses and when I put them on I am seeing double images. Is this normal? They are multifocal lenses. I have already been wearing my old glasses today, would that make a difference, or could the script be wrong?

    • Kieran Hunt
      March 17, 2014 | 2:58 pm

      Hi Wendy,

      It’s possible that you need to wear your glasses as much as possible each day to adjust to your prescription, but if you are seeing double it’s unlikely that you are just adjusting to it. I think it’s possible that the lab or doctor made a mistake with your pupil distance measurement. My suggestion is to bring them back to the doctor to have them checked.

    Hey so my trouble is that every year that I’ve been going to the eye doctor they’ve said my eyes are the same in prescription. Last year both were 4.25. I recently went to a new optometrist and she gave me 4.25 on one eye and 4.0 on the other. Can one eye really just get better .25 randomly? I really think she just didn’t examine my eyes well. She focused more on one than the other. What should I do? I’m thinking of getting a second opinion but that’s going to cost me…

    • Kieran Hunt
      March 17, 2014 | 3:16 pm

      Hi Rose,

      It’s definitely possible for your eyes to get better. As counterintuitive as this is, it’s not uncommon. If the new prescription doesn’t feel right, however, you should be able to go back to the eye doctor for a replacement pair and new examination at their expense, since it was the optician’s mistake. I hope this works for you and helps you to avoid the extra cost of a second opinion.

    Hi my prescription recently changed. When I wear my new glasses the right eye is perfect but the left eye feels like it is pulling towards the center. It has that feeling like when you purposely try to cross your eyes. I get headaches and a sick feeling. My left eye also feels like it has something in it like an eyelash always there. When I wear my old glasses all that disappears and I am fine.

      Hi Jack,

      It sounds like your pupil distance may have been done incorrectly on the glasses. I suggest taking them back to the optician who made them and explain your problem. I don’t think it’s you; it’s probably a mistake on the glasses.

    I received new glasses yesterday and I am finding that the vision in my right eye is very blurry looking straight on or angled in towards my nose, whereas if I look through the outer edge everything is extremely clear and focused. Basically I keep turning my head to a slight left to see better. Is this normal? I was told by the optician to give myself a week to adjust but it just feels wrong. She told me my old rx was as follows:
    pl -4.50 x16
    -50 -4.00 x162

    My new rx is:
    -.075 -5.00 x020
    -.075 -4.00 x167

    Thank you.

      March 27, 2014 | 12:11 am

      Hi Andrea,

      It may be that you need to adjust for the week, so I suggest giving that a try. If, after the week is through, you still feel that the glasses aren’t right, bring them back to the optician. I suspect that they made a mistake with your pupil distance. Your change in prescription seems normal.

    I have a new pair of glasses with progressive lenses. I have always been very slightly near sighted, but have never been regular with wearing my glasses in the past. My vision is just blurry enough to be a nuisance, but not incapacitating. But now I need the reading magnification. My new glasses have a -.75 rx in each lens, and I see clearly out of each eye individually. The problem is they give me double vision when using both eyes, and my peripheral distance vision is blurry as if the lenses are smudged and need cleaning except in the very center. My old glasses never did this. Is it a normal result of the progressives?

    • Kieran Hunt
      April 21, 2014 | 8:57 pm

      Hi Jo,

      Progressives often take a while to get used to. If you are not used to them by now, it could be that the lab made a mistake on your pupil distance, or it could be that you are a progressive non-adapt. I suggest you contact the doctor’s office you got them from and let them know that you’re having this problem.

    Hi. I just bought a new pair of glasses for the first time. After more than a week of using it I feel like the right glass isn’t right as it is disturbing as if something is blocking. And it cause my right part of the head aches bec. of the fuzziness but I can still see clearly though with the 2 eyes open. If i would close the left eye It seemed blurry or okay I can’t explain.

    I suspected I may have a wrong prescription and afraid it may cause me again.

    Do you think it is just for the adjustment period?

    • Kieran Hunt
      April 21, 2014 | 8:59 pm

      Hi Mary,

      If you are still having this problem after a week of wearing the eyewear regularly, it could be more than the adjustment period. After a week, I suggest you contact the eye doctor if you’re still having problems.

    My doctor told me my right eye is dominated so he gave me stronger lens for right eye. But I had left eye stronger before by .5. After a week, I felt my left eye tried and stressed so I went back to doctor’s office. I found out that my left eye I can’t see the mid line and below. A week ago, I was in his office tested my eye and the left one can see the mid line. Do you think my left eye had been changed dramatically because doctor gave me too strong on my right eye and I used ? Does this happen to anyone else?

      April 24, 2014 | 2:26 pm

      Hi Susan,

      That is not something that I’ve heard of. Typically, a prescription does not change your eye after only a few weeks of use, and I don’t think it’s possible for a bad prescription in one eye to change the other eye. Sorry you’re having these troubles, it could just be a coincidence.

    HHi, I received new prescription glasses. They were perfect in the right eye but blurry in the left, the left also made me feel like my eye was pulling and gave me headaches. I brought them back, I got the glasses checked by the optician and then retested by the eye dr. He gave me a prescription closer to my old lenses but they are still blurry in the left eye. I have worn them for a week and a half and they are still the same. It is frustrating and I don’t know what to do. I have regular glasses and sunglasses and they feel the same way.

    Hello, Ive had the same -2.00 prescription for more than 5 years now. I went in for an eye exam and the doctor increased my prescription on one eye and now I also have a slight astigmatism. Right eye is -1.50 ~ -0.50
    Left is -1.75 ~ -0.50… I’ve never had an astigmatism before and the doctor didnt even talk to me about it before I left. I was just wondering when I get my new glasses will there be a big difference because of the astigmatism. How will I know if its wrong?

    • Kieran Hunt
      May 6, 2014 | 1:41 pm

      Hi Stacey,

      You’ll probably notice an improvement in clarity if you’ve developed an astigmatism and your new glasses correct for it. You probably have nothing to worry about – the glasses will feel clear and will probably take a day’s adjustment, like any new glasses. If you have problems with the prescription, however, I suggest you bring them back to the doctor to talk about it.

    Hi, I just got a new pair of glasses from a different eye doctor than my last glasses I got. With these new glasses I feel like am looking through a fish bowl. Its like everything is curved around me. The only difference is these new glasses has reflective coating stuff put on them, my old ones don’t. Do you think the reflective coating could be causing the fish bowl effect?

    • Kieran Hunt
      July 5, 2014 | 4:15 pm

      Hi Roy,

      It sounds like your doctor used a different base curve, which is the starting curvature of the front of the lens, to make your glasses. If you’re in a new frame and the frame is curved, it would make sense to use a more curved lens. If you’re in the same frame as before, it makes less sense but is not that uncommon.

      Anti-reflective coating would not cause the fishbowl effect.

      I suggest you go to the place you had your eyewear made and speak with them about your problem.

      Please let me know if you have any more questions.

    I just received my first pair of progressive lenses a few days ago, and I know there is supposed to be an adjustment period. I had a bad headache by the end of the first day wearing them but haven’t had one since and am now trying to figure out how to look out of them as I switch back and forth from distance (computer) to nearness (paperwork). I did order them online and now realize I probably should have gone in person to get this first pair. Anyway, I was wondering if the problems continue if took the glasses to an optician with my prescription if they’d be able to tell me if the lens are correct?

    • Kieran Hunt
      June 25, 2014 | 1:25 pm

      Hi Jen,

      Yes, if you took the glasses to an optician you’d be able to determine if the lenses are correct. However, it is common in the optical world for opticians to claim that a prescription is wrong when it’s actually fine, because they want you to come to them for your glasses. So, it’s important to find an honest optician.

      Also, it sounds to me like your segment height is off. This would impact how well you’d be able to switch from distance to near vision while wearing the glasses. Since this was your first pair, I agree that getting them done in person would have been better, but for now you should get them checked out to see what a local optical professional has to say.

    Just came upon this site while looking for answers to my glasses issues. I recently had a dramatic change in glasses RX- Old +2.00 (L) +1.25 (R) add of 1.25. The Doc said I was an early presbyope at 38. Now 2 years later new RX + 0.75 (L) 0.50 (R) and add of 1.25. However, after wearing the new RX for more than a month to ensure proper adjustment, the eye strain and neausea with and without them does not seem to be getting better. The strain is centered in my mid forehead area. I am thinking of getting a second opinion.

    Just came upon this site while looking for answers to my glasses issues.
    I received a new prescription this weekend from a new eye doctor and had glasses made.
    I have problems now reading my computer screen and vision is also blurry when reading.
    My old prescription in June 2013 was, OD -350, CYLINDER -50, AXIS 95; OS -325, CYLINDER -50, AXIS 32.
    My new script reads od -350, cylinder -50, axis 104, os -325, cylinder off, axis off.
    Could the new script be causing the blurriness in my reading, I called the doctor and he told me that I needed reading glasses.
    I tried to explain to him I could read fine with my old glasses why would my reading vision be worse with new script? He had no answer , also said my astigmatism was mild so didn’t need to be treated in left eye, I am confused.
    Thank for your help.

      Hi Jerry,

      Did you get bifocals on this prescription or your last prescription? Your prescription should probably have bifocals in order for you to be able to read.

    Hello, I got new glasses about a month back and they appeared to be fine, but in the last few days I have been experiencing ghost vision on my tv It only happens on a digital device or tv the writing will appear doubled and It gets worse at night is it my glasses ? My vision is fine when im not using my phone or watching tv but i also feel sime eye strain.

      Hi Rory,

      It sounds like your glasses need anti-reflective coating to help with this distortion. This double image is caused by many types of lenses, but this can be avoided with anti-reflective coating most of the time. Did you get them from us? If so, you can send them back to get A/R in most cases.

    I got ‘new’ glasses a couple months ago ( Around 3 months ago ) and I wore them for a couple of days and suddenly forgot to wear them until now. I just recently put them on and noticed that my left eye felt uncomfortable when I put it on. I closed one of my eyes and when I blinked, my left eye went a tiny bit blurry for a second and returned to normal. I can see perfectly fine though besides the tiny blurriness that lasts for a second. Did my prescription change or is it just my eye trying to get used to it?

    I’m a nearsighted and I received my new glasses two weeks ago, but I’m afraid I’ve got a wrong prescription. My left eye is weaker than the right one and when I wear my new glasses the right eye is stronger than the left so I have trouble when I take them off since its the opposite. I’m I putting pressure on my right or both eyes?

    I’m 18 and have been in and out of the eye doctor for the last two years for way more visits than I should have. I’ve found a new eye doctor and I got a prescription from him, which worked great for a few weeks and then I couldn’t see enough to feel safe driving at night. I got a new prescription, which was fine, and now everything has a bit of a glowy blurriness around it. Should I go back?

    • Kieran Hunt
      July 16, 2014 | 12:38 am

      Hi Emily,

      You should go back to the eye doctor immediately, as rapid changes in your vision can be a serious issue, and the eye doctor should look into what’s causing them.

    I feel my glasses are not right but am afraid to go back and tell them my problem as i’ve already been back twice and one of the manager’s make me feel like i’m just being a nuisance! My eyes are very uncomfortable and i just can’t deal with it any longer! What do i do?

    • Kieran Hunt
      July 16, 2014 | 12:40 am

      Hi Lorraine,

      It’s unfortunate that the manager made you feel that way. My personal opinion is that your vision is of paramount importance, and it’s the optician’s responsibility to do right by you and make you a usable pair of glasses so you can see. Go back, and if the manager gives you attitude, tell them you wouldn’t be coming back if they’d given you usable glasses.

    I have recently started wearing glasses again after a two year gap. I was told I have developed a significant stigma in my left eye. It seems now with the glasses on I am having an issue with my computer screens and the way they look. I am getting a keystone effect when I change the way my head is looking at the screen. right side of If I close one eye (either one) this effect disappears. It only looks that way through both lenses at the same time. Also getting headaches behind the left eye, but expected those for the change period.

    • Kieran Hunt
      July 16, 2014 | 12:41 am

      Hi Todd,

      All of that is normal for the change period. If they still feel wrong or give you problems after a week or two of wearing them regularly, I suggest going back to where you got them to have the prescription checked.

    Ok so today I got new glasses (I haven’t had new glasses in a few years) I’m also a contact wearer and I’ve only had contacts for about a year now. Well anyway so ya I got new glasses today and they make me have a slight headache and nausea when I wear them. They also make bright objects appear to have a yellow and blue line on the sides of the object. I think they might’ve messed up where my pupil was but I’m not entirely sure. They also make the screen of my iphone appear to tilt to the right of the screen. Please help!

      Sounds like something is not right it could be a bunch of different things causing your problems. Is this a new prescription from the doctor. If so make sure its correct. If the rx is correct go back to where you got your glasses and double check to see if they are correct.

      • Cathryne
        August 6, 2014 | 4:39 am

        Thank you for your answer but I think it’s just I get nauseas when ever I switch from glasses to contacts or the opposite,because of the depth perception difference makes me have a headache and nauseas (note if I atleast switch from glasses to contacts atleast pence a month it’s fine

    You probably didn’t see my question so I’ll ask again.
    I’m nearsighted and my left eye is weaker than my right and when I got my glasses the lens of my left eye is stronger than my right so it’s the opposite of my vision. I don’t know if both lenses should be the same. I’m I putting pressure on my eyes? Would my left eye get worse?
    Thank you.

    • Ryan Phillips
      July 21, 2014 | 6:36 pm

      You prescription can be different in both eye’s there could be something wrong with your Rx. I would suggest you going back to the eye doctor to check everything out.

    I received an eye exam and two new pairs of glasses (one pair of clears, one pair of sunglasses) about a year ago. The clear glasses I see perfectly out of, but the sunglasses I don’t. They are not as clear as my old prescription nor the new clear glasses I received. I have taken the glasses to two different places and they say the prescription is the same. If it is, then why don’t I see the same with both pairs of glasses? The prescription is as follows:

    Clear glasses
    Right SPH -1.25
    CYL -1.00
    AXS 103 degrees
    PD 29.5
    Left SPH +0.00
    CYL -.50
    AXS 65 degrees
    PD 30.5

    Right SPH -1.25
    CYL -1.00
    AXS 102 degrees
    PD 31.0
    Left SPH +0.00
    CYL -.50
    AXS 67 degrees
    PD 29.0

    Please help because everyone thinks I’m crazy, but I know my eyes and those sunglasses are not right. Thank you!

      Hi Kristi,

      It sounds like you’re having a problem with adjusting to a curved lens, which most sunglasses have.

      Are the sunglasses a wraparound style, or do they have curved lenses? If so, the curvature of the lenses could be the source of your problems. Some people’s eyes can’t adjust to curved lenses. This is because the eye performs differently when looking through curved prescription lenses compared to flat prescription lenses, even though the prescription may be the same. The curvature of the lens has an effect on how your eyes work because your eyes move, and whenever they do they need to refocus in a different way because they’re looking through the lens at a different angle.

      Some people’s eyes can adjust to this different perspective with no problem. Other people’s eyes simply cannot adjust, no matter how long they try to use the eyewear. If this is the case for you, it simply means that you can only use prescription sunglasses in flat frames, such as the classes “wayfarer” style that the Blues Brothers wore.

      Let me know if you have other questions, or if you believe that this is not the answer to your problem.

    I recently got 3 new Paris of glasses. One for normal activity one for work (safety glasses) and some sun glasses. All 3 are supposed to be the same prescription but the sun glasses are causing serious problem. Basically the vision I get from them is not even comparable to my other pairs of glasses. I’ve had three different frames now and 4 sets of lenses and the problem is still there. We’re all total baffled as to what’s causing this and it’s most annoying as I have to wear a really old pair of sunglasses that was at least two prescriptions different to this one. Any advice greatly appreciated.

    • Kieran Hunt
      August 7, 2014 | 2:09 am

      Hi Gavin,

      Are the sunglasses a wraparound style, with curved lenses? That could definitely be the source of your problems. Some people cannot adjust to curved lenses, as your eyes need to perform differently and respond in a different way when looking through a curved prescription. Some people’s eyes take to this with no problem, but others simply can’t adjust to it. You may be having this problem. If that’s the case, you’ll need to order your sunglasses in a flat frame like a wayfarer (Blues Brothers sunglasses).

    Just wondering. If you see better when you pull your prescription glasses slightly away from your eyes, does that mean the prescription is too weak or too strong? Thanks.

    • Kieran Hunt
      August 7, 2014 | 2:07 am

      Hi Pat,

      That generally means that the pupil distance is not correct on the glasses or that the optical center of the lenses are in the wrong places. You should take them back to the place you got them to have them evaluated for this.

    I am 42 years old ,I recently went to the eye doctor (for the first time in my life) because I have been having a hard time reading small print like newspapers and books and also I can’t read a thing with my right eye, it is very blurry but my left eye is not that bad and as long as I have both eyes open I can see fine for the most part except small print. The optometrist gave me a prescription of Right Eye +3.00 and Left Eye +1.00 and told me to wear my glasses full time.Do I really need to wear my glasses full time since my left I isn’t that bad?

    • Kieran Hunt
      August 25, 2014 | 2:17 am

      Hi Ray,

      Without knowing your full situation, I really can’t say whether you need to wear them full-time. I suggest following your eye doctor’s advice, as he/she probably told you to wear them that often for a specific reason.

      Please let us know if you have more questions!

    Hi there
    I’ve just got my first pair of perscription reading glasses after wearing cheap $20 Kmart ones…stupid I know !!! But I’m finding that I prefer the cheap ones-the clarity and size of the text is perfect (with the cheap ones ) where as the clarity of the perscrition ones is not as good,I’ve been back twice to the opticitions and feel like I should go to a different optician.The frames are quite big,so I’m not sure if this makes any difference. Is this just an adjustment period or should I go back again?? Thanks Nicky

    • Kieran Hunt
      August 25, 2014 | 2:27 am

      Hi Nicky,

      If you’re doing fine with the cheap readers, I don’t think you need to get prescription glasses. Plenty of people have this issue. If you have trouble reading for long periods or get headaches or eye pain from reading for a long time, you should probably just find a new eye doctor and try to get a prescription that works for you.

      Please let us know if you have more questions!

    I’ve had a huge problem getting glasses this time around. The people at the shop where I had my exam and bought new frames were certain that it was a lens problem, not a prescription problem. Three changes later (after changing lens material, then PD, then correcting an anti-reflective coating error), and the distance in my left eye still isn’t as sharp as it should be (even though those changes did help a bit). I can get by since my right eye is fine, but it feels like my left is straining.

    I don’t have the time or patience or trust at this point to go back to the same shop for yet another change, and if it IS a prescription error, I’m worried that I’d go through a few more pairs trying to get the lenses right!

    With my vision insurance plan, it would actually be cheaper to order a couple of glasses online with tweaked prescriptions than get reexamined at a different optician’s and pay for new frames / lenses there.

    So, my 2-year old prescription:

    OD -4, -1.5, 85

    OS -4, -0.5, 100

    My recent (and not quite right) prescription:

    OD -4, -1.25, 84

    OS -4.5, -.75, 114

    It’s this left eye I’m having a problem with, chiefly for distance (though titles on books about 5 feet away form me are a bit blurry, too). It’s not ideal, but I could order one or two pairs online with different prescriptions. Should I tweak the sphere a bit to -4.75? Are the changes in axis and cylinder really big enough to question their accuracy or the impact they’d have on sharpness of image? If so, should I order a pair that tweaks one or both of those numbers a bit?

    I know getting re-examined by an optician would be ideal, but I just don’t want to have to drive out to this eye doctor’s place for…the 9th time? Especially if they screw up the lenses on the new prescription 3 more times!

    • Kieran Hunt
      August 25, 2014 | 2:34 am

      Hi Jen,

      You can try to tweak your prescription, but it’s really a gamble as to whether you’re going to make it work. It could be the sphere, cylinder, or axis.

      You can at least test the axis. With your right eye closed, rotate the glasses while they’re on your face so that they tilt with your left eye as the center of the turn. Turn them slowly in both directions (lift them off your right ear while letting them press down on your left ear, then do the opposite) to see if that helps your clarity. If it doesn’t you can rule out axis as being the problem.

      Do you see more clearly out of your left with your old prescription? If so, you might want to consider averaging the two prescriptions, or just getting the old prescription in the left eye.

      You’re right, the ideal situation is to go to an optometrist and get it fixed by a doctor. I recommend that. However, if you really want to try to order glasses and risk it, try these things and let us know if it works!

I have been back and had the lens remade but am experiencing the same thing with the new lens. Just where do I go now??

      Hi Pam,

      Do you have progressive bifocals, and is it your first time getting them? If so, you may be having a hard time adapting to them.

      Otherwise, it could be that your frame is too curved, or you need a new optometrist :(

    My prescription has been changed and I have got a new glasses yesterday. But whatever I’m seeing with this spects, that the images are bit stretched. For ex. The Round shaped watch is looking bit oval shaped even a human faces. I’m so confused whether the prescription are wrong or the lense is less qualitied one or its nothing but just a new spects effect. Please help me to rectify the problem.

    And my power is -3.25 for on OD and -2.00 on OS both axis 105 sph for OD is -0.75 and OS is +0.00 and its a single vision.

    Hi Kieran,
    Please can you help?
    I had an eye test last September at my local Opticians and because the cost of varyfocal prescription was high it wasn’t until this June that I was able to afford them (£800).

    But instead of going back to the local Optician to make up the spectacles (they couldn’t get the right frames for me)I went into town and had them made up there.

    Since having these new specs I have been suffering from migraines and really horrendous headaches. A few days ago I closed my right eye and looked through the left finding my vision blurred. When I swapped eyes, the right eye is fine and clear.

    Today, I returned to the local Opticians and had my specs checked alongside the prescription and found that they don’t match. She said I see better through the lens of the prescription rather than through my specs, she says there is a little deterioration in the left eye but unsure at this moment as to why.

    I have been asked to go back in tomorrow to have another eye check, just to check for eye health, etc.

    The problem I face is what rights do I have to have to ask for the lens to be changed free of charge(at the in-town Optician) and as they need to be sent away to be changed I have no other specs to wear until they come back. I go back to work next week which will make things very tricky, to say the least.

    What kind of compensation can I ask for, if any?
    I would be extremely grateful for your advice.

    Did you buy them through us? If so call our customer service reps so they can assist you in correcting this error. If you bought them else where then I suggest you go back to the original place that made the glasses and see what they can do for you. Be sure to have your eyes examined yearly. Some places offer a warranty check with them.

    I recently got a new prescription in my glasses, and it’s great. However, I also got new sunglasses with the same prescription, and something is wrong with them. Specifically in my right eye, it’s blurry. The prescription was double checked to make sure that they’re the same, and they tried adjusting the lenses in the frames, but they’re still bothering me. What could this be?

    I recently got a new pair of glasses, I was using the same pair of lenses for seven years and never had the prescription updated. It was a narrow frame, with polycarbonate lenses…I recently got reexamined….and the left eye prescription stayed the same but the right eye prescription increased. Because of the new lenses I was advised to get high index lenses, I also selected a more modern, larger rectangular frame. The prob is I have been having issues returning to “normal” vision…sometimes I feel I’m having issues with depth perception… Especially up close…far off everything is fine. Also my right eye hurts and goes red. Are all these an adjustment side effect? And if not how long should I wait to adjust, its been about ten days…thankz

    So I received glasses after 2 years of contacts. I put them o and my left eye is Crystal clear where as my right eye sees worse with the glasses on. Not to mention the fact that things are distorted (warped if you will) through my right eye. I was told to wear them a week, but its so bad through my right eye that I believe there’s no way the lab got that lense right. What do I do?

    This is the third year in a row that I have gotten a bad pair of progressive lenses. Just last week, I picked up my new glasses. Horrible headache, eye strain, etc. I closed my left eye and the right eye looks great – distance, mid and reading. When I close the right eye, and look just through my left, distance and reading are ok but I actually have to turn my head slightly to the right to have clear mid-vision. What could be wrong? The prescription axis or cylindar adjustments or were the glasses measured wrong on my eye? Every year it’s a problem with the left eye. I just don’t understand why they can’t get it right. Please help. I’m going back to the store on Saturday to try to get the problem resolved. So frustrating. Thank you.

    Hello. I was wondering… I am a migraine sufferer. I recently got a pair of progressive lenses that I just could not handle. I had migraines every day. It took some convincing, but the eye care place finally believed me and suggested bifocals instead. I have tried the bifocals forma week now and have had horrible headaches or migraines every day. There are places in the lenses that I see double and I am not sure, but maybe the bifocal line is too high. I feel like I have to look up a lot. The line is very distracting. Can you tell me if I am just not giving it enough time, if maybe something needs to be fixed or if I just need to go back to regular glasses? I don’t think the difference in the prescription is very different right now. Thank you for your consideration.

    I just got my first pair of glasses yesterday. The Dr told me I am near sighted and have astigmatism. It’s a small prescription. He said my left eye is a little bit worse but to come back and we will adjust after I get my glasses. Well from the moment I put on my glasses I see crisp and clear in the left but my right eye is like it ant focus. When I close my right eye, my left is fine. And when I close my left eye, my right seems to be fine. But when both eyes are open my right is like there is something blocking my sight, it’s kind of fuzzy and just not focusing. It hurts and when I take them off it takes a long time for my right eye to feel and see normal again. Could my right be over prescribed or wrong prescription or wrong pupil distance? How long should I wait before I go back? Thanks.

    I’ve been wearing glasses/contacts for 10 years now. I recently went to the doctor for a routine exam. My prescription changes from -1.00 in left and 1.75 in right to -1.25 left and -1.50 in the right. My right eye has typically been the stronger of the two, but according to the recent exam I was surprised to see it’s no longer the case. After trying the new prescription contact lenses (acuvue oasys, same I’ve always used) I noticed that my left eye contact had a more crisp, clear focus. The right eye, however, felt much different. MY ability to focus on objects 10 feet away and 20 feet away was not as strong as I could with my old prescription. There were times with my left eye closed that my right eye almost felt as though I had a fish-eye lens on. Reason enough to have it rechecked?

    December 17, 2014 | 6:57 pm

    I got two pair of eyeglasses today (sunglasses and regular), and the sunglasses aren’t right at all. the store double checked the glasses and said they were identical prescriptions in both sets. (she used that little microscope-looking machine to check.) However one is definitely worse than the other. I have a bad astigmatism (4.75) and have worn glasses for over 30 years- this is the worst transition I’ve ever experienced. They want me to wait a week to see if it’s still bad, but the fact that one is OK and the other isn’t, is troubling.
    So, my question is- does the astigmatism make it difficult to check if prescriptions are the same? is there anything that could make them be the same prescription, but have such different results when I look out of them?

    thanks for any insight!

I just got my new prescription almost 2 weeks ago and I’m only having problems with seeing electronic devices clearly.

    Dist -0.25 +1.25 165

    The following is what my glasses were filled as. I questioned why the prescription was changed and they optician said it was filled correctly and the numbers were changed for reasons I would not understand unless I was in the optical profession.
    I had a plano sphere in the rt. eye and it was changed to a +1.50 and the left eye had a sphere of -0.25 and they changed it to +1.0 It looks like everything was changed. Please tell me if the prescription was filled correctly.

    This is the way the prescription was filled.

    Rx Spherical Cylindrical Axis
    Dist +1.50 -1.50 95
    Dist +1.0 -1.25 75
    Near +2.50
    Near +2.50

    Did you purchase the glasses from us?

    Hi! I wear mainly contacts but am trying to wear my glasses more. My contacts prescription hasn’t changed but my glasses prescription has. I’ve gone from 8 in my right eye to 8.25, and my left eye remains at 8. I’m wondering if my right eye will eventually become weaker from wearing the glasses causing my contact prescription to go up as well, which is now -7 in each eye.

    Thank you!

    This is my third glasses. I had wear glasses for about 13 years. For my first and second glasses, my myopia had stayed 1.00 for both eyes. I just got my new glasses two weeks ago.

    My latest prescription as below:
    Left: 0.00-0.25
    Right: 0.50-0.75

    Left: 0.50
    Right: 0.75

    My new glasses are (myopia, astigmatism):
    Left: 0.25, 0.50
    Right: 0.50, 0.75

    I realised that my new glasses are lack of focus, and I felt dizzy and headache after wearing the new glasses for a while, or when I turned my head.

    I see clearer with either eye (although I think my right eye’s vision is not clear enough, but my optician told me that I do not need to get the full power for my right eye), but with both eyes, the vision is blurry.

    I noticed that there are some difference between the focal points of my new and old glasses.
    New glasses (Left, Right):90,90
    Old glasses (Left, Right): 85,90

    My old glasses are as follow (Myopia, Astigmatism):
    Left: 1.00, 0.25
    Right: 1.00, 0.50

    Because recently my left eye was very uncomfortable when using the old glasses, that’s why I went to get a new glasses. The optician was very surprised when he noticed there is improvement to my myopia.

    Could you help to identify the problem of my new glasses?

    Many thanks.

    Personally, I am really not too familiar with Myopia. Make sure you have your prescription checked in your new glasses to make sure it matches your RX. Sometimes a small adjustment in the glasses or frame style can distort the prescription.
