Vision combines output from both eyes {binocular vision}|. Cats, primates, and predatory birds have binocular vision. Binocular vision allows stereoscopic depth perception, increases light reception, and detects differences between camouflage and surface. During cortex-development sensitive period, what people see determines input pathways to binocular cells and orientation cells [Blakemore and Greenfield, 1987] [Cumming and Parker, 1997] [Cumming and Parker, 1999] [Cumming and Parker, 2000].
One stimulus can affect both eyes, and effects can add {binocular summation}.
Visual-cortex cells {disparity detector} can combine right and left eye outputs to detect relative position disparities. Disparity detectors receive input from same-orientation orientation cells at different retinal locations. Higher binocular-vision cells detect distance directly from relative disparities, without form or shape perception.
People using both eyes do not know which eye {eye-of-origin} saw something [Blake and Cormack, 1979] [Kolb and Braun, 1995] [Ono and Barbieto, 1985] [Pickersgill, 1961] [Porac and Coren, 1986] [Smith, 1945] [Helmholtz, 1856] [Helmholtz, 1860] [Helmholtz, 1867] [Helmholtz, 1962].
Adaptation can transfer from one eye to the other {interocular transfer}.
