Definitions:

Retinal Disparity

The slight difference in the visual images that reach each eye, leading to perception of depth.

Stereoscopic Vision

The ability to perceive depth and three-dimensional structure from visual information derived from two slightly different perspectives provided by the two eyes.

Binocular Inversion

A visual phenomenon where the vision is flipped upside down due to the use of devices that invert the light paths reaching the eyes.

Binocular

Pertaining to or involving both eyes, especially in providing stereoscopic vision or depth perception.
