ABSTRACT:
Improved eyeglasses for use by color blind individuals or viewers. The eyeglasses are constructed to have two lenses, one of which is clear and the other of which is colored. Each lens is formed to have a reflective or mirror surface as viewed from the front of the eyeglasses. When worn by a color blind viewer, the combination of lenses improves the color blind viewer's ability to discriminate between different colored objects while the reflective or mirror surfaces cause the lenses to appear to be identical to other persons or viewers.
