> But, actually, I wear glasses when I'm in front of a computer for any extended period of time. I'm what they call (in Norwegian, I don't know what it's called in English) "over-longsighted", a term I don't really understand, since it doesn't mean what you'd think it means. I don't have trouble seeing things close up (like "normal" longsightedness), but I can see things far away better than most people I know. It's fun being able to read signs much farther away than my friends. :-)

I read something like this... Apparently some western Australian Aborigines have 80/20 vision, so they can recognise landmarks in the desert (which believe me, has very few landmarks)...
