Abstract: An eye dominant training device comprising a track sewn into the front brim of a sun visor that accepts a wrap around clear plastic material, referred to as a graphic display shield. The shield slides in and out of the track for easy replacement. The shield when placed in the track covers the eyes completely but does not go down beyond the bottom of the nose or below the bottom of the ears at the wrapped position. The shield has a clear generally rectangular window for the placement of master and testing graphic displays which may be in the form of decals. The testing graphic displays are sued for determining present eye dominance if any. The utilization graphics display includes one circle in front of either eye for the sole purpose of viewing a target through the circle with a line matrix including one tilted horizontal line with several vertical lines placed next to the circle. The circle is used as an object focusing device for the eye being trained.
