I n normal vision the eye is constantly in motion. Small involuntary move­ ments persist even when the eye .is "fixed" on a stationary object. As a result the image of the object on the retina of the eye is kept in constant motion. One movement of the eyeball makes the im­ age drift slowly away from the center of the fovea, the region of maximum visual acuity in which the cone receptor cells are most densely concentrated. The drifting motion terminates in a flick that brings the image back… Expand
