I can't wear contacts anymore (suddenly). Anyone else have this problem?

About a year ago, my contacts suddenly started irritating my eyes and within a few days of the symptoms starting, I could no longer wear them at all. I’d been wearing contacts for about five years prior to that with no problem. I went to the eye doctors when the symptoms first started, and when I left his office, I could no longer stand contacts at all. My eyes burn, dry out, get red, water, etc. A few months later, I could wear them for a few hours to work out or go out. Now, I can’t wear them at all and my eyes are super sensitive even when I don’t wear them. I’ve been to two opthamologists (multiple visits) and none of them can seem to fix the problem. They said that I am just allergic to the material… and none of their solutions or prescriptions or new contacts have alleviated the problem at all.

I hate the idea of having to wear glasses forever, or until I can get Lasik. I’m only twenty and in otherwise perfect health. Anyone have similar problems? Any solutions?
