Ocular dominance, sometimes called eye preference or eyedness, [1] is the tendency to prefer visual input from one eye to the other. [2] It is somewhat analogous to the laterality of right- or left- handedness ; however, the side of the dominant eye and the dominant hand do not always match. [ 3 ]
Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans [1]) that respond preferentially to input from one eye or the other. [2] The columns span multiple cortical layers , and are laid out in a striped pattern across the surface of the striate cortex (V1).

To observe flash suppression, a small image is first presented to one eye for about a second while a blank field is presented to the other eye. Then a different, small image is abruptly shown, flashed, to the other, second eye at the location corresponding to the image to the first eye. The image to the first eye disappears, even though it is ...
The dominant eye is determined and vision tested to identify the level of correction required for distance and near on the dominant eye and non-dominant eye. The analysis of ocular dominance and patient specific interocular suppression and binocular rivalry [ 12 ] also allows for ensuring the eyes can work together to create the Laser Blended ...
If the brain never learns to see objects in detail, then there is a high chance of one eye becoming dominant. The result is that the brain will block the impulses of the non-dominant eye. In contrast, the child with myopia can see objects close to the eye in detail and does learn at an early age to see objects in detail. [medical citation needed]
The layers representing the deprived eye in the lateral geniculate nucleus of the thalamus are atrophied. In V1, ocular dominance columns representing the open eye are dramatically enlarged, at the expense of cortical surface area representing the sutured eye (Fig. 1 - Effect of monocular deprivation on ocular dominance columns. Light areas ...
Binocular rivalry was discovered by Porta. [6] Porta put one book in front of one eye, and another in front of the other. He reported that he could read from one book at a time and that changing from one to the other required withdrawing the "visual virtue" from one eye and moving it to the other.
