I wear contacts. Don't own glasses, never have, never will.
My vision sucks ass. I'm like 20/40 now in one eye, and 20/80 in the next. Course, corrected I get 20/15.
Still, likely getting laser surgery by the end of the year.
Here's some doctor no-nos that I never listened to:
1) Replace contacts every 2 weeks. I did like every 4 months
2) Don't swim or shower in contacts
3) Don't sleep in contacts. Mwahahahaha!!! Think the longest time I ever had my contacts in without taking them out was 8 months
Now with no-rub I actually take them out at night. Before it was a pain, so I left them in. When one fell out, i'd replace it. Man, I'm such an idiot

Anyway, if you don't feel like taking them out one day, it won't kill you.
