Principle of binocular vision with horopter shown. In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and ...
However, most predators have both eyes looking forwards, allowing binocular depth perception and helping them to judge distances when they pounce or swoop down onto their prey. Animals that spend a lot of time in trees take advantage of binocular vision in order to accurately judge distances when rapidly moving from branch to branch.
The cheiroscope is used for diagnostic purposes to test binocular vision, to assess certain conditions of strabism in particular related to binocular stability and alignment, [2] cyclotropia, [3] and the presence and extent of suppression. [2] It can also be used in vision therapy to train amblyopic subjects in desuppression and eye–hand ...
MV is related to, though distinct from, computer vision. [8] 3. Three dimensional art Three-dimensional art is observed in terms of its height, width and depth. It is not flat like two-dimensional art, which consists of paintings, drawings and photographs. Pottery and sculpture are examples of three-dimensional art. Form is the three ...
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
Binocular vision has further advantages aside from stereopsis, in particular the enhancement of vision quality through binocular summation; persons with strabismus (even those who have no double vision) have lower scores of binocular summation, and this appears to incite persons with strabismus to close one eye in visually demanding situations.

Orthoptists are mainly involved with diagnosing and managing patients with binocular vision disorders which relate to amblyopia, eye movement disorders, extraocular muscle balance such as with version, refractive errors, vergence, accommodation imbalances, positive relative accommodation and negative relative accommodation. They work closely ...
