Why Don’t My Eyeglasses Work Anymore?

Why Don’t My Eyeglasses Work Anymore

As an eye doctor, seeing patients each day, people ask me this all the time.  “My glasses worked fine when I got them but now, I don’t see as well with them.”  Everyone tries cleaning them, but that doesn’t fix their problem.

Eyeglasses Correct Focus – So What Changed?

You know that eyeglasses only help your eye to get focused.  So, if your vision is not in focus there are only two issues to consider.   If the eyeglasses focused well when you got them, then the prescription is probably correct, though you can have your eye doctor remeasure this to be certain.

How Your Eyes Focus: The Cornea and the Lens

The second thing to consider is that the problem is that something has changed with your eyes.  There are two parts of your eye that deal with focus: your cornea (the front clear wall of your eye) and your lens (located inside your eye behind the colored iris).

Dry Eye Disease: The Most Common Culprit

The most common problem with the cornea is Dry Eye Disease. This is likely the problem if your glasses don’t work well when you are tired, or doing intense visual activities like working at the computer or staring at the TV.  It can be a problem on certain days when there is dust or smoke around your eyes, but it can also be caused by aging, hormonal problems, nutritional problems, allergies, medication side effects, and lots of other things.

You can check for this by putting an artificial tear eyedrop in your eye, blink a few times and see if the glasses work better.  If that helps, it may indicate what your problem is.  You can certainly use these eyedrops as needed to help your eyes see better, but that doesn’t solve the problem.  Just like a wig doesn’t fix bald spots, the eye drops just cover up the problem.

Dry Eye Disease can get worse over time and even cause serious problems for your eyes if it is not evaluated to find the cause and correct it.  The Dry Eye Institute has specialists with the skill and experience to find the cause of the problem and recommend the most effective way to correct it and keep your eyes healthy and seeing clearly with your glasses.

Cataracts: Clouding the Natural Lens of the Eye

The natural lens in your eye also works to give you good focus, but with age and some disease and even as a side effect of some medications, it becomes cloudy.  That is what is called a cataract.  A quick eye exam can determine if a cataract is developing to make your eyeglasses no longer work correctly.

Diabetes and Vision Changes Throughout the Day

Diabetes is a condition where your blood sugar can vary during the day, and that will also change the way your eye focuses. Even if you are on medication to control diabetes, your blood sugar can rise during the day and change the way your eye focuses.  It can happen after meals or snacks and change your vision before the medication brings it back into control.

That is a common reason why eyeglasses don’t seem to work correctly sometimes, and not other times.  A specialist can check you for diabetic eye disease and help your doctor work with you to regulate your blood sugar levels to avoid this problem.

Why a Basic Vision Test Might Not Be Enough

Routine eye exams that just measure you for new glasses don’t always find these problems. So, you need to have your eye doctor do a full health examination to catch them and correct them.
