Eye Dominance
When each eye has its own image of objects, it becomes impossible to align images outside of Panum's fusional area with an image inside the area. This happens when one has to point to a distant object with one's finger. When one looks at one's fingertip, it is single but there are two images of the distant object. When one looks at the distant object it is single but there are two images of one's fingertip. To point successfully, one of the double images has to take precedence and one be ignored or suppressed (eye dominance). The eye of the image that takes precedence is called the dominant eye.

Famous quotes containing the words eye and/or dominance:
“There are a thousand unnoticed openings ... which let a penetrating eye at once into a man’s soul; and I maintain ... that a man of sense does not lay down his hat in coming into a room,—or take it up in going out of it, but something escapes, which discovers him.”
—Laurence Sterne (1713–1768)
“It is better for a woman to compete impersonally in society, as men do, than to compete for dominance in her own home with her husband, compete with her neighbors for empty status, and so smother her son that he cannot compete at all.”
—Betty Friedan (b. 1921)
