stereopsis
Two-eyed depth perception
Stereopsis is the perception of depth that arises from having two eyes.
Because each eye views the world from a slightly different angle, the brain combines these two images to create a sense of three-dimensionality.
Without stereopsis, you can still judge distance through other cues—relative size, shadows, motion—but the direct sensation of objects occupying space is diminished or absent.
