Yay, I have a chemical burn on my right eye.
It would seem that when I bought what I THOUGHT was my usual contact cleaning solution (same extact box, same extact location in the store), it was not the multi-purpose solution that can go near your eyes. 16 years of wearing contacts and I've never heard of such a thing. I don't know why they make it, except that the doctor said some people are allergic to the usual daily solution. You'd think a product that's used on stuff that goes in your eyes would advertise more clearly that it shouldn't make contact WITH your eyes, even in very tiny amounts.
The good news is according to the doctor, I acted quickly enough, clawing the contact out of my eye and rising, rising, rising, that there doesn't seem to be any serious damage. I can't wear contacts for 3 days and I have to treat it with some stuff, but hey, eyesight still in tact!
(PS: if you've ever wondered what even a small amount of hydrogen peroxide feels like in your eye....don't.)
