Ocular dominance, sometimes called eye dominance, is the tendency to prefer visual input from one eye to the other. 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.
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. That's correct because I am left eye dominant but ambidextrous (the ability to use both my hands and feet with equal ease or facility).
Take the test here.
