i've worn contacts since i was 19 or so. i can't imagine why i didn't get them sooner. the best is being able to wear sunglasses and not look stupid and crash into stuff. also, snowboard goggles. also, you have perpherial vision.
i also sold some friends on them, they were like "they're expensive, i can't", and i was like "yo check out 1-800contacts.com"
