My Eyes Are Different Sizes and It's Noticeable in Pictures Can This Be Fixed by Cosmetic Surgery?

This is usually due to one eyelid being droopy or in a different position.  An oculoplastic surgeon can evaluate the eyelids and eye sockets to assess why you have the asymmetry and give you options, which may include doing nothing. Cost depends on if it is a functional problem or cosmetic and can range from several hundred dollars if you are paying along with your insurance up to several thousand dollars if it is purely cosmetic and paid for out-of-pocket.

Without a picture this question cannot really be addressed. Either resubmit this question with photos or see a surgeon for evaluation. You have to be over 18 or be accompanied by a parent or guardian to be evaluated and have surgery or possibly neuromodulator treatments. Costs cannot be determined without having some idea of what needs to be done.
