Eye Dominance *
Ocular dominance, sometimes called eye preference 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. To test this if you are unsure, make a circle with your thumb and first finger. With both eyes open look at an object on the wall or in the distance, and center it inside the circle. Now close one eye, and then the other. If the object seemed to move when you closed your left eye, then you have left eye dominance. If the object moved more when your right eye was closed, then your right eye is the dominant one.
