Comment Re:I HAVE NO DEPTH PERCEPTION!!! (Score 5, Interesting) 94

You're far from being alone.

Many people (about 10%) lack *stereopsis*, the ability to fuse to slightly different images from the two eyes so that the brain perceives depth.

But stereopsis is really just the icing on the cake of depth perception, and just as you say, people use all kinds of other visual cues to perceive depth, with the brain doing the processing subconsciously to a great extent.

Lack of stereopsis is so little a handicap that most people lacking it are unaware of the fact; orthoptists (the paramedical professionals who measure squints and treat amblyopia) have special tests to pick it up.

My favourite is the Wirt Fly:

I've known perfectly capable eye surgeons who lacked stereopsis.
