Binocular Vision

Also found in: Dictionary, Thesaurus, Medical, Financial, Acronyms, Wikipedia.


The combined vision of two eyes (binocular vision). Stereopsis is one of the ways depth is perceived by the human brain. Other methods include the larger size of close objects and smaller size of distant objects even with one eye (monocular vision). The term comes from "stereo," which means "solid" and "3-dimensional" plus "opsis," meaning sight. See 3D visualization and stereoscopic 3D.

Binocular Vision


vision with two eyes. In binocular vision, the visual axes of the eyes are arranged in such a manner that the images of the object viewed strike the identical portions of the retinas of both eyes. This produces a single stereoscopic image—a view of the world in relief. Binocular vision also makes it possible to determine visually the relative location of objects in space and to judge their distance from each other. When looking with one eye—that is, with monocular vision—the distance of objects can likewise be judged, but not as accurately as with binocular vision.

It seems clear, that binocular visual information supports the performance of skills such as grasping (Coull et al., 2000), catching (Olivier et al., 1998) and locomotion (Patla et al., 2002), but it is unknown whether binocular vision is needed to be effective in the performance of a more complex skill, involving a whole body rotation, like the handspring on vault.

Patients with divergent squints most commonly present between the ages of 1 and 4 years; the condition nearly always remains intermittent and is therefore associated with good binocular vision. Vertical ocular deviations occur in children, in isolation or associated with horizontal strabismus, but are much less common and are not discussed here (Donahue 2007).
