eyeball226: If you don't mind me asking, is it because of monocular vision or is there another reason you don't have depth perception?
Hell if i know, it's a gene thing inherited from my father, one eye wants to, the other eye doesn't care. I used to have something with "lazy eye" thing, which was fixed with a few lasers, prisms and some annoying thing using light [they use a tool to flash light in Your eye, then let You watch colorful spots on the walls. In the end, i've regained a sh..load of vision in my right eye [basically one eye sees all on Snellen chart, the other sometimes sees most, sometimes up to 5 rows;P]. So i have hyperopia and myopia, depending on the eye. Kinda cool. ;P
I don't use glasses for almost 10 years, but i still don't see 3d. When i'm tired my eye likes to jump a bit. And in those annoying 3d glasses i see a purple screen with a green blur somewhere in the middle. Meh.;>
[edit:] Playing volleyball and basketball sucks ass with this. Soccer is fine, because the ball is usually on the ground.
