Abstract

The problems of road visibility hold a special position in road safety. On the average, up to 15% of all accidents take place in conditions of limited visual range. One of the main reasons for road accidents is that the upper beam of head lamps of the opposite-direction vehicles dazzles a drive. The driver experiences a painful sensation at a distance of 200 meters or less. After termination of the dazzling effect the eyes' relaxation comes tens of seconds later; it means that some 400 meters the car moves without guidance. In this paper an anti-dazzling device, preventing the upper beam of head lamps of opposite-direction vehicles to dazzle a driver, is described. The device consists of 2 electrooptical liquid crystalline shutters, the goggles casing and of electronic control circuit, allowing to vary the light transmission of the shutters, as the illuminance of the photodetector varies.
