Three years ago my eye sight pretty much dropped from perfect to shit. A year ago I started wearing my glasses full time, I don't take them off until the end of the day when I go to bed. I usually forget they're there. But considering I wear them all the time, I shelled out on a really nice frame. :P
I do have and wear glasses. At first I didn't need them that much, but now I wear them most of the time. The only time I take them of is if I am at home.
