A DEVICE FOR MINIMISING GLARE

摘要

Spectacles (1) for use by a driver of a vehicle for minimisign glare from the headlights of an oncoming vehicle comprises a frame (2) with lenses (4) which are formed by panels (5) having an electro-optical medium (20) laminated therein. The panels (5) of the lenses (4) define respective bands (32) of pixels (26) which are selectively operable in a hight transmitting mode and a light attenuating mode. A CMOS camera (40) monitors the brightness of light in the field of view of a subject, and on the brightness in any region of the field of view exceeding a predetermined level the pixel or pixels (26) in the respective bands (32) corresponding to the region in which the brightness of the light exceeds the predetermined level are operated for attenuating the light in that location for in turn minimising glare from the light source.
