Abstract
A device has been developed for protecting vehicle drivers against bli nding nighttime glare. The device activates at an illuminance level of 1.4-2 lux on the driver's eyes and reduces the light flux from the he adlights of oncoming traffic by a factor of 10-50. The technological f eatures of the light shutters based on the twist effect in nematic liq uid crystals are described, and the angular dependences of the device transmittance are given.
