I wear glasses for driving (reading street signs etc), but I hate wearing them otherwise. I went to a concert last night and couldn't see the first band very well - all I could tell was that there were 3 people, 1 girl and 2 guys, the girl was blonde and she was wearing a purple t-shirt, and one of the guys had long hair and wore an orange t-shirt. Luckily there was a break between that first band and the person I was there to see, so I was able to get my glasses from the car and I could actually make out her eyes, nose and mouth.

I've had the same lenses for 9 years though, so I'm well overdue for a checkup. I wouldn't be surprised if I needed a different prescription lens. I can see pretty well without glasses though. I am short sighted (myopic).
