COUNTER-DAZZLING GLASSES Russian patent published in 2006 - IPC G02C7/10 A61F9/04 G02F1/135 

FIELD: optical engineering, in particular, engineering of counter-dazzling means, possible use for screening eyes of driver from dazzling light, in particular from cars moving in opposite direction.

SUBSTANCE: counter-dazzling glasses have frame with glasses, protective screen with cells and a matrix of light-sensitive elements, electrically connected to protective screen, additionally included is infrared eye pupil position indicator, generating signal under effect from infrared radiation from pupil, gate matrix with normally darkened cells and slit formed in it imitating eye pupil position, adjusting assemblies. Gate matrix is electrically connected to infrared pupil position indicator through adjustment assemblies, is mounted with possible letting of dazzling radiation through slit formed in it onto matrix of light-sensitive elements and following transmission of signal to it for darkening of protective screen cells for protecting pupil from dazzling radiation.

EFFECT: possible alteration of light-protective layer of glasses with consideration of diameter and mobility of driver eye pupil.
