According to an exemplary embodiment of the present invention, the vehicle window mirror rearview assembly may include an electrochromic mirror device having a variable reflectance (110, 920), a glare sensor (160, 234) for detecting a level of light from the rear of the vehicle toward the front device, A second ambient light sensor 232 for sensing the level of ambient light, a display located behind the partially transmissive and partially reflecting portion of the reflector for displaying information, and the control circuits 230, 900 connected to the display ). The control circuitry determines whether the day and night conditions exist as coefficients of the ambient light level sensed by the glare sensor to control the contrast ratio of the light reflected from the partially diffused and partially reflected region of the parasitic light from the display and the reflector.
