Claim 0:
1. An optical apparatus that simulates visual scotomas for basic and clinical research, and for diagnostic, prognostic, therapeutic, and commercial purposes, comprising:
a. at least one spectacle lens that plane polarizes light and demarcates the directionality of polarization;
b. a spectacle frame that allows said spectacle lens to rotate, wherein the degree that said spectacle lens is rotated from the vertical meridian is known and the plane of light polarization is also known by comparing the directionality of polarization demarcated on said spectacle lens with the degree of rotation indicated on said frame; and
c. at least one contact lens, each with a plurality of areas that each polarize light in a different plane, wherein light that passes through said spectacle lens and subsequently through said contact lens is restricted from reaching specific areas of one or both retinas of a user, depending upon the angle differences between the planes of polarization of said spectacle lens and each plane of polarization within said contact lens.
