How the eye sees color

Last week i broke my glasses while i was in the mountains and had to use scotch tape to keep one of the lenses from falling out. Today i was supposed to superglue them back together, but since that means not having my glasses on for an hour or so, i have procrastinated. Instead i spent the afternoon spelunking on the internet and reading about things like why colorblindness is more prevalent among men and how the eye sees color.
