Binocular vision

Also referred to as stereoscopic vision, it is an ability restricted to animals with eyes on the front of the head, and involves a combination and comparison of the information received from the eyes, used in the stereoscopic aspect of depth perception, but also in a number of other ways.  Binocular vision contributes to depth perception at close distances (within 18-20 feet), but beyond that, the brain relies on less precise cues, such as shadows, and in particular the relative motion of objects at different distances to generate depth information.
