How does someone who has lost an eye get over the initial loss of depth perception?

Answer 1

Although losing an eye can affect depth perception, we have a number of monocular cues that enable us to retain a degree of depth perception even with only one eye - after all, if you close one eye, the world does not suddenly become flat!

For example, if we see two similar objects, one large and one small, our brain assumes the smaller one is further away. Or if we see one object superimposed over another, we assume that it is closer to us.

"Tricks" like these have been used by artists for centuries to give their paintings an impression of depth, despite being entirely 2D.
