The present invention is directed to a therapeutic device that enables the user to effectively treat cortical visual impairment. The therapeutic device comprises a base； a light source within the base capable of generating light in a variety of colors； a light diffusing layer positioned above the light source such that the light diffusing layer is substantially uniform in color when illuminated by the light source； a substantially opaque grid located above the light diffusing layer； an upper light source located above the substantially opaque grid at a sufficient distance to allow physical items to be placed on top of the opaque grip； and the upper light source further positioned such that the upper light source illuminates the upper surface of the substantially opaque grid.
