Abstract
A mirror (10) with a pair of vertical dazzle light attenuation zones (24 and 26). Each zone consists of stripes (24a, 24b, . . . 24n, 26a, 26b, . . . 26n) capable of dynamically adjusting the widths and the attenuation intensity of the attenuation zones (24 and 26). The mirror (10) has a multi-layered structure containing a liquid crystal (32). The positions and widths of the stripes are controlled manually via adjustment pushbuttons (20 and 22), or automatically, in response to the intensity of the incident light. When a driver sees during night driving the reflection of the dazzling light in the non-attenuated areas of the mirror, the driver's head is slightly moved, or the driver manually shifts by pushbuttons (20 and 22) the groups of the attenuated stripes (24 and 26) to the position where the dazzling light (L) will be covered by these stripes. The localized attenuation of the mirror's surface will not disturb the overall view observed by the driver through the rearview mirror (10).
