yeah, i'm blind :( but you can swim, just keep your eyes closed, otherwise you'll lose them. I've had them for like 4 years and the only ones i had a problem with were the yearly ones, within the firs month i had ruined 2 pairs, now i have monthlys and have had no problems.
Eeeek!! My icon makes me look like my face is a big fat circle!
My theory on dogs:
If you can kick it across the room. It's not a dog!!
