A question about my eyes...

Duh. You have your own pair of glasses. Wear them.

yes if there normal sunglasses, no but if there reading glasses or ones that are required for people with eyesite thats a bit worse that yours, yes using other peoples galsses not specified for you strains your eyes and over time it can damage them leading to permnanent vision damage so everything will be blury try not to do it because theres no need to do it anyway

I won’t, because like I said… I didn’t like them anyway. I only had them on to see what Iooked like in the mirror. They didn’t fit well with my face… I thought I looked like an old lady lol

Well no not really, not unless you had them on for a long period of time :)

if you wear someones elses glasses? yes you can make your sight more worse and damage your eyes. so I would think you shouldnt wear them again
