Abstract
An optical glare limiter uses an electrical power source, typically of a motor vehicle. It includes a light sensor component and a light source. The light from the glare limiter light source falling on a reflecting surface depends on the intensity of the light falling on the light sensor component from an external blinding source and can be regulated electronically so that the light in the driver's field of vision has a contrast that is almost homogeneous and widespread with the effect of reducing the blinding effect.
