Abstract
A filtering vision element forming a windshield or rearview mirror of a road vehicle includes a lower region and an upper region. The filtering vision element is designed so that a difference in attenuation between two linear polarizations of an incident radiation has values that are of opposite signs in the lower and upper regions. The two linear polarizations may respectively be horizontal and contained in a vertical plane. Blinding of the driver caused by a spot of reflected light produced on a road by headlights of an external vehicle may thus be decreased or prevented.
