My eyes had begun to fossilize by the time I was in 4th grade. I still remember taking the eye test - There were various sizes of the letter "E" and you had to point which direction they were facing, I could see the top, largest one, after that everything was a gigantic blur! At least I knew why I was so crappy at baseball and shooting marbles!
I'm close to being legally blind and don't see very well at night, the LEDS are cool and I'm thinking a little that a set of those might be fun on one of my 'Birds. - Cool stuff!
