DAZZLING PROTECTION METHOD AND APPARATUS Russian patent published in 2002 - IPC

FIELD: medical equipment, in particular, dazzling light protection facilities. SUBSTANCE: method involves changing intensity of light flux directed to human eye by turning polarizers one with respect to another around optical axes. One polarizer is positioned in contact lens fixed on eye and other polarizer is set on light source. Polarization planes of both polarizers are mutually perpendicular or arranged at an angle of about 90 deg one with respect to another. Polarizers fixed in contact lenses for left and right eyes are oriented so that their polarization planes are extending in mutually parallel planes. Apparatus has combined contact lens of soft optically transparent material with central body formed as disk located inside transparent material in axially aligned relation with respect to optical part of contact lens. Central body is made from material possessing polarizing properties. Lens is provided with mark indicating identical orientation of central body polarization plane. Method and apparatus are used for protecting actor's eyes from dazzling effect of projectors in theater, circus, during shooting etc. EFFECT: increased efficiency in eliminating dazzling effect of light sources located in certain directions. 6 cl, 3 dwg
