Because of exotropia[0], I have extremely limited binocular vision. I have had several surgeries to keep my eyes from drifting off to the side but essentially all of my distance vision comes from size and context clues. Driving at night is difficult because it's hard to compare the sizes of headlights.

I (obviously) don't watch 3D movies too often. When the technology first came out, it was really bad and gave me not-quite-headaches, not-quite-nausea when wearing glasses. It's better now but I don't get nearly the effect that the movie makers are going for and some of the more blatant effects (like things jumping out of the screen) end up looking weird and off-putting -- like getting half an image and stuff.
