Yeah, I'm myopic (short-sighted), and I have had to wear glasses since I was six. It's pretty bad, I guess, but I can still make my way around without them. I can't read stuff off a whiteboard or anything like that, though, so I need them for school.
I've considered switching to contacts a couple of times, but no. I don't need them. I'm comfortable about being a glasses-wearer, and it's not like they get in my way. Hell, I can even play badminton while wearing them, so what's the point? Coloured contacts would be neat, though; I wouldn't mind having purple eyes every now and again.
