Stereopsis and stereoblindness is actually a fascinating topic. Some humans don’t have it, and still manage to drive, ride bicycles, or fly planes.
The Mind's Eye by Oliver Sacks has an interesting chapter on a woman who managed to develop stereovision in her late 40s through vision therapy.

- fudged71 9y agoSome VR users (and IMAX 3D customers) have reported 'learning' stereovision. I'm pretty sure I'm stereoblind. I think my brain is too lazy to combine images into 3D. Pot seemed to kick my brain into overdrive and process that signal. My friend laughs at me for "seeing in 3D for the first time" and doesn't believe me.
