Yesterday I was up in the high altitude mountains, and today, I've noticed that a small part of my eye is a little bit red. I think it is sunburn.
1. It doesn't hurt. Scale of pain from 1 to 10 = 0.5 (slight sting)
2. I can still see perfectly fine.
3. This is the first time I've ever been sunburnt in the eye.
I don't know if it's critical, but I've just been a bit worried.
