Human stereoscopy is only good out to a few meters (and presumably people aren't going out with giant WWII stereoscopic rangefinders to generate training data). So it wouldn't help them for things like fireworks or trees.
Found out I couldn’t see in stereo.
Got prism glasses. Completely blew my mind to seen ”depth” for the 1st time. Had no idea I couldn’t. Never had any trouble.
Apparently without prism glasses my vision just switches from one eye to the next every 30 seconds. Completely seamlessly.
No. They are for double vision. Had a series of small strokes. Caused high cranial pressure which caused six nerve palsy. I take a pill now and it fixes double vision. I lose stereo that way. But prism glasses are very distracting to wear.
