ABSTRACT:
An opaque plate is positioned in front of a patient undergoing color vision testing. A number of openings are formed in the plate. Behind each disk is a hollow sphere having colored light sources mounted therein. By selectively energizing the colored light sources in a sphere, a mixture of light is presented at the corresponding transparent disk at a selected intensity. A tester can select one or more spheres to be internally illuminated by color light sources so that the patient is presented with a pattern of selectable color mixtures which checks his color vision.
