Snowblindness is cool, but how damaging? I was at school, during an offclass the other day. We were bored, so we figured we'd go out and play soccer on the back field. Everything's covered with snow still. We go back inside for lunch, about an hour later. At first, I can't see anything, its all dark. Lightens to shades of green and blue. About a minute later I can make out some colors. But everything white & grey appears like it would under a black light. My friends called it snow-blindness, I wasn't aware that's what it actually was, but anyway. What kind of damaging effects, if any, would this have? I've never worn sunglasses, and it didnt seem *blinding* while I was on the field... Any thoughts?
