I started wearing glasses last year, but I gladly changed to contact lenses.
I don't wear glasses because:
It causes red marks on my nose bridge.
I have to be really cautious while moving around so that I don't knock it off with something (it happened many times, I'm a cat)
I drink hot beverages a lot, so it always produce a fog on my glasses.
Sometimes while moving my eyes around, I see part of the glass, and part of non-glass - so I see a distorted view.
I noticed I get headache with it.
Wearing lenses is easier for me, I put it on when I wake up, and take it off when I go to bed. It was a hassle at first but it's quick and easy now. Plus, I don't feel it in my eyes.
