Abstract: A light control device for a vehicle, includes a distance detector and at least one controllable polarizer. The distance detector detects the distance between a first vehicle in which the distance detector is located and an interference light source. The at least one controllable polarizer is configured to perform a polarization process on light to weaken the intensity of the light when the distance between the interference light source and the first vehicle is within a predetermined range; otherwise stop the polarization process on the light.
