1. Visual perception of depth which is a result partly of binocular vision and because the visual stimuli transmitted from each eye goes to both brain hemispheres.
2. The perception of depth, distance, and three dimensionality arising from binocular vision.
3. Vision in which the visual fields of the two eyes are unified.

Sensations from a common object received by the two eyes are superimposed, and as a result of the slight differences in the fields and the superimposition of the fields, the effects of depth and shape of the object are determined.
