Why? Because I cried on Monday. Does this happen to anyone else? If I cry with my contacts in, they're like /torture/ for weeks after. Even with a super-duper weekly cleaning, even with daily scrubbing, they feel seriously dry and they're cloudy to look through. Very uncomfortable, they make my eyes very tired and hurting.
I'm guessing that the extra tears put more oils? or something? on them, and so gas and liquids can't get through them like they should, but that's just a guess. I've worn contacts for 15 years now, and it's always been like this no matter what brand I get. (Always soft contacts though.)
