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.

Abstract: The invention relates to the field of management of an active lens and more particularly to a management system comprising an active lens (1), a first sensor (2) arranged to measure data relating to an incident light on the active lens, a control unit (4) designed for controlling the active lens according to data measured by the first sensor, wherein the management system further comprises a second sensor (3) arranged to measure data relating to a light transmitted from the incident light through the active lens, the control unit being further designed to adjust, according to said data measured by the second sensor, the control already performed according to said data measured by the first sensor. Thus the management system allows taking into account data relating to the light passing through the active lens as a feedback in order to finely control the active lens.

Abstract: The invention relates to a transparent electrochromic system (100) which includes two pairs of transparent supply electrodes (1-4), which are intended for being electrically connected to variable power sources (20, 21). The electrodes of the two pairs are supported by separate outer walls (10, 11) of the system, on either side of a closed volume which contains electroactive substances. The electrochromic system has superior dynamics and switching rate. Various embodiments of the invention correspond to various modes for connecting the electrodes to the power sources, and to various partitions of the closed volume into separate cells (13).
