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.
