Abstract: A performance enhancement aid for sports activities and the like in which it is necessary to keep the eyes focused on a target. The aid may be an assembly which is mounted on the user's eyeglasses or the eye direction panels may be permanently fixed to a frame which is worn on the head in a manner similar to eyeglasses. A pair of opaque panels are supported on opposite sides of the user's eyes. Each panel has a forward portion which extends obliquely inwardly toward and aligned with the optical axis line of the adjacent eye when the user's eyes are focused on a target. Each oblique extension defines a desired sight line. The two defined sight lines converge at a line bisecting the angle formed by the optical axis lines of the user's eyes, thereby directing the user's eyes to the target.
