I think my vision is like 20/40 or 20/50 without glasses, so it's not perfect, but it's not so bad that I'm blind without my glasses. (I have a friend who is like 20/200 without glasses). I often forget to wear them. I need them if I want to see smaller text, (like in class). I would need them if I wanted to drive, but I can't drive for other medical reasons anyway so that comes out with the wash.
I remember I just avoided wearing my glasses for a long time. I got them in middle school, but I never wore them really until 11th grade. Even then, I wore them for aesthetic purposes mostly, because I thought it would make me look older. (I was a late bloomer so when I was 17 I looked like I was 11 lol). They did actually help me see the board a little better, but I remember at the time I considered that a bonus.
As for which eye is better, I think my left eye is better. I do remember my right eye started getting blurry first because when I was around 11, when I covered my left eye, things would look slightly blurrier. I think my left eye is still a bit better than my right.
As for contacts, absolutely 100% NOT! I can't handle anything near my eyes at all. I remember when I was a teenager I had to get eye drops and I lost my mind. Like, full on freaking out, hyperventilating, panic attack, the whole shebang. Wasn't fun at all. I'm also terrified of surgery so no laser anything okay bye lol.
