Dominant eye in vision

Ocular dominance, sometimes called eye dominance or eyedness, is the tendency to prefer visual input from one eye to the other.

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.

In normal binocular vision there is an effect of parallax, and therefore the dominant eye is the one that is primarily relied on for precise positional information.

This may be especially important in sports which require aim, such as archery, darts or shooting sports.
