i can't cross my eyes unless i point my finger to the bridge of my nose and try to stare at it...then my eyes do a bit of a cross...which just lasts but a moment =(
but a few years ago i remember my friend getting her eyes checked by the optometrist, and she said that he got her...
I always enjoy cross eyed action by my friends, but I cannot do it myself. I would love to entertain my friends doing that, but I hear it is not good for the eye. How nice it would be to be able to do that without straining the eye.
For some odd reason... When I try to cross my eyes... I look down or up. They never gravitate towards the CENTER of the eyes. They always roll up or down. Like not in the middle and down or the middle and up... But just like I'm looking straight down or straight up. It irks me.
