I have a prescription (glasses), but I rarely ever wear them. My eyesight isn't that great for long-distance viewing (terrible maybe?), but it's good enough for 99% of my intents and purposes. Except for staring at cute girls. I wear them when I go out usually just so I can see the cute girls more clearly. My eyesight was perfect when I was younger, don't know what happened. Maybe it's from sitting in front of computers for too many years.
