the single perception of a slightly different image from each eye.

stereopsis

binocular vision

The visual perception of a fused single image from 2 eyes viewing the same object from slightly different vantages. Binocular vision results from the convergence of neural signals from the corresponding points on the 2 retinas on the same binocular cell in the primary visual cortex. If the images received from each eye differ widely in shape, orientation or luminant contrast, the images then rival each other rather than fuse.

ster·e·op·sis

(ster'ē-op'sis)
Depth perception (three-dimensional vision) provided by fusion of binocular images.
See also: depth perception
Synonym(s): three-dimensional vision.
[stereo- + G. opsis, vision]

The normal ability to perceive objects as being solid. Stereoscopic vision.
