My New Glasses Feel Too Strong

By rxsafety

The symptoms are unmistakable, and occur from the moment you put on your new pair of glasses; objects seem either too close or farther away than they should, or move at a bit of a blur.

Are My New Glasses Too Strong?

Your vision seems super-sensitive, hyperactive. Sometimes people describe the effect as “tunnel vision.” It could be any or all of the above.

However the condition manifests itself in your case, you’ll know it when it happens. Your brand new glasses simply feel too strong. What happened? Was a mistake made in cutting the prescription, creating lenses that are a diopter or two off from your required vision correction setting? Did the optical exam you recently underwent miss something, or misdiagnose your prescription?

It’s possible. Mistakes like that do happen. Your prescription can be slightly off even if no error is made at the eye exam; if, for example, your eyes are tired after a long day when you had the exam performed. (It’s recommended that you try to schedule an optical examination when your eyes are “fresh,” such as in the early morning or during days when you won’t be spending several hours at a computer monitor.) Sometimes mistakes of the old-school variety at to blame – poor handwriting on a prescription form, miscalibrated machinery, etc.

These problems, however, are relatively few and far between. What’s more likely is that you simply need time to adjust to your new lenses. If you’ve had any change in prescription strength, for either eye, your eyes need an adjustment period to become acclimated to those changes. Light is now being directed through your eyes’ lenses just a little bit differently than it used to; the muscles that position the eye and the photoreceptors that process the information need to compensate for these developments.

Even if your prescription stays exactly the same, new glasses can seem strong and somewhat “off” for a period of time. Lenses change with age – minute scratches, fading, and gradual yellowing alter them very slightly over the years, and your brand new lenses are crisp and clear. The difference might not be obvious, but it’s there. Vision is also altered by other factors, such as additional tints or coatings on your new lenses that weren’t present on your old pair of glasses. Even different frames or lens shapes can alter the way your eye process visual information, requiring an adjustment period for you to get accustomed to new glasses.

Regardless of the reason, the feeling that your glasses are too strong should gradually dissipate, and by two or three days of constant use, your eyes should completely adjust to the new lenses. If they do not, a revisit to your optometrist may be in order to confirm your prescription or determine if the lenses are at fault. Just be sure to wear the new glasses throughout the adjustment period. It’s tempting to switch back to your old familiar pair, but doing will reset your eyes’ new training period.

    I had 2 retinal detachments in same eye Aug and Oct 2019 in which the macula detached as well. A cataract was also removed at same time so I now have -9 in unaffected eye and -3 in affected eye. There is a slight distortion remaining. I feel that the new prescription for the affected eye is slightly too strong but the optometrist says is correct based on reading the eye chart etc. Would it not have been better to base the script on looking at both eyes as a whole given that vision in the affected eye causes distortion the smaller the letters and therefore can give a false reading?

      Hi Ginnie,

      When you get your eyes examined, the doctor should have tested each eye separately (whether you cover one eye or they use their machine to cover an eye) and then they test your eyes together. Distortion could be from the style frame you are wearing, if there is any type of curve to the lens. The material could be playing a part. If you are using a high index material for a thinner lens in the -9, that can cause distortion. I would present some of these questions to your eye dr and I’m sure they can make recommendations to get it all sorted out for you.

      Hi there,

      It takes about a week to get adjusted to new prescription eyeglasses. If you are still facing those symptoms after a week, I would suggest you go to your eye doctor and get your eyes checked again an your prescription reevaluated.

    I just got new glasses and it felt like it was lower than usual. Changed the lenses but I’m not still so satisfied. I think my glasses as a myopic patient should enable me see tiny and very tiny writings from afar. Right?

    I just got new glasses and the prescription seems REALLY strong. My eyes have become a little worst and havent changed my glasses/prescription in them for 2 years. I got some today and now I have a really bad headache, I feel like whenever I see out of them everything is somewhat rounded on the edges which is weird. Is this normal?

    • jsiddiqui says:

      Hi, it typically takes about 2 weeks to adjust to new glasses. If you are experiencing difficulties even after that you should go for an eye exam again and have your prescription reevaluated.

    I recently had my contacts updated to a stronger prescription, which is great. So i decided to use the same optometrist and get a pair of glasses since my old ones are not the correct prescription. They’re single vision glasses , I am near sighted. But these new glasses seem off, when i take my contacts out and switch to glasses it’s as if things look thinner and longer in only one of my eyes. I have different powers for my left and right eye. I am trying to let my eyes adjust but it is frustrating that my contacts are correct yet my glasses don’t deliver the same and they are brand new.. I’ve had them for three days and am wondering whether I need to wait longer before going back to the optometrist

    • jsiddiqui says:

      Hi Meghan, you should typically wait for about a week to see if you are able to adjust to your new glasses. If things are still distorted after a week, go back to your optometrist and have your eyesight rechecked and your prescription reevaluated.

    I just started to wear glasses and got two classes one was for free since I was
    A new customer at my eye place and the glasses I picked feel different one feels fine when used and the other kinda is blurry and kinda not and my eyes feel like they got to focus more and I called to ask why I felt this way with the one and he said it could be for reading but it’s like I don’t read so they will lay around so now I ain’t sure what to do it don’t feel right when wearing them and want to use for only reading:/

    • jsiddiqui says:

      Hi Jennifer,
      I recommend that you to your eye doctor and have your prescription revaluated, and your glasses checked.

    My new glasses make things look smaller at an angle and I went back to the optometrist and he said I just need to wear them all the time which I didn’t. I’m hoping it all works out because I like my eyes and I don’t want them to get worse
