The apparatus includes a housing for occluding substantially all visual perception from an exterior environment for a non operative eye, the housing including a cover, with an internal surface that forms a plane approximately perpendicular to the non operative eye line of sight axis. Also included is a visually perceptible element adjacent to the internal surface being in visual communication with the non operative eye and structure for moving the visually perceptible element within the plane to any selected position, the apparatus is operational to help the non operative eye focus on a selected line of sight position upon the visually perceptible element with the result in assisting in the operative eye achieving a stable selected line of sight position.
