Abstract: The present invention is directed to a method and apparatus for assuring that dynamic glare-shielding devices are properly characterized for the optical arrangement of a particular user by using a plurality of calibration points, thereby assuring the maximum effectiveness of such devices.

Abstract: The invention may be embodied as a glare detection system or as a method of detecting glare. In a system according to the invention, there may be a light receiving surface, a first input channel, a second input channel, a glare signaling circuit and a glare reducing circuit. The first input channel may provide an indication of the amount of light impinging on a first portion of the light receiving surface. The second input channel may provide an indication of the amount of light impinging on a second portion of the light receiving surface. The glare signaling circuit (“GSC”) may have a first input port in communication with the first input channel, a second input port in communication with the second input channel, a logic-or gate capable of producing an output signal when the logic-or gate detects that the first input channel or the second input channel indicates glare on the light receiving surface.
