My eyes are not really "symmetric". For example when I'm trying to sleep and that itchy feeling starts in your eyes - it only feels in the right one! Also when crying, most tears come from the right eye. And when it's bright outside there's clearly a blueish tint when looking with one of the eyes only.
I may have confused right with left though. Does everyone have it this way or is it just me? Always wondered.:P:shock:
