Contact vs. Glasses Problem
jacif posted:
I recently broke my glasses and had to get a new pair. I went to the optometrist, he gave me a prescription, and I got it filled at a local chain. However, I can't see through my glasses - I've been back to the glasses store 5 times and they have supposedly "fixed" the glasses 3 times; I've gone back to the Dr. to have him check the prescription, and it seems fine there. The biggest problem is switching between my glasses and contacts. My contacts are perfect - I have no vision problems whatsoever. When I remove them at night and switch to my glasses, everything is so blurry I may as well not have them. Oddly enough, I can see just fine when I turn them over...
I'm looking for an educated opinion on what may be the problem. Is it the prescription, or the glasses manufacturer? Help!
Alan M Kozarsky, MD responded:
Lots of possibilities why vision provided with contacts may seem much better than glasses.

Especially with very strong prescriptions, contact lens vision has less magnification or minification than glasses with much more natural vision.

An eyeglass prescription may be correct but the lenses may not be centered in the frames for the position of your eyes. Checking lens centration is frequently missed.

Sometimes the busiest places making glasses attracting customers by deals and discounts are not the most accurate in filling prescriptions. Keep this in mind especially with strong prescriptions and for progressive bifocals. Solving subtle or complex eyeglass issues may not be part of their expertise or business model.

Vision may be somewhat blurred immediately after removing contact lenses and putting on glasses.

That's really interesting, Dr. Kozarsky. I have the exact opposite problem where I see better with my glasses than I do with my contacts.

When I get home in the evenings after work, take out my contacts, and put my glasses on, I feel like I see things far clearer & crisper. Any ideas why that may be? I got my glasses & contacts at the same time so I don't think it's a Rx issue. I guess it could be.

Alan M Kozarsky, MD replied to ElizabethTracy's response:
Yes, some people do see better with glasses than with their contact lenses. An example of why this might happen is someone with astigmatism which is corrected by their glasses but not by their conventional (non-toric, not astigmatism correcting) contact lenses.

Couple things it could be is the material itself, not to frequently but sometimes people can be sensitive to the material the lens is made from. Going from plastic to polycarbonate or even if you have worn verilux lenses in the past. Also, did your old glasses have an anti glare coating on them? if they did not and you used that coating in the past, that could be causing issues too. When you say you can see them fine when you turn them over, do you mean having the right eye look out of the left lens? When you went back to your eye doctor, did he give you another exam? or did he just simply read the Rx of the glasses? Your eyes could have changed slightly, but not enough to be effected by your contacts, but enough to throw you glasses out of whack.
