Abstract: The lighting of a person via incident light radiation is controlled to address dazzling. The light radiation originates from a source of light and passes through a medium of variable and controllable opacity. The position of the source of light relative to the person can vary. A zone of the eyes of the person and a position of the zone of the eyes relative to the medium is detected. A incidence of dazzling of the zone of the eyes is detected. In response to the detection, the direction of incidence of the light radiation is determined. From this determination, from the position of the zone of the eyes, a region of said medium is identified that has a projection on the face of the person which includes said zone of the eyes. The opacity of the region of the medium is then modified in a controlled manner to preclude dazzling.
