Abstract
A transparent and polarizing vision element (2) divided into several areas. At least two of said areas are associated with a luminous polarization filter. The light flowing through the element is allocated differently for two the areas according to a direction of polarization of the light. At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element.
