Answer: 2. Inflammation of cornea due to high dose of UV-B radiation

Snow-blindness is inflammation of the cornea caused by a high dose of UV-B radiation.

In polar regions snow reflects a lot of UV-B, and the thinner ozone layer lets more of it through, so the cornea gets damaged. It is not due to freezing, mere brightness, or infra-red damage to the retina.
