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).

In boxing and some other sports, a southpaw stance is a stance in which the boxer has the right hand and the right foot forward, leading with right jabs, and following with a left cross right hook.
Ocular dominance columns are also found in the striate cortex. These columns were found to prefer crossing iso-orientation lines perpendicularly. During microelectrode experiments, it is normal to see penetrations where eye dominance changes between the contralateral eye and ipsilateral eye but this does not interrupt the orientation sequence.

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.

These fish demonstrate an individual eye preference when examining their reflection in a mirror. Fish which show a right-eye preference in the mirror test prefer to be on the left side of the school. Conversely, fish that show a left-eye preference in the mirror test or were non-lateralised, prefer to be slightly to the right side of the school.
