A vehicle rearview mirror system includes an electro-optic reflective element, an ambient light sensor that is operable to sense ambient light, a glare light sensor that is operable to sense glare light and a circuit that is responsive to the ambient glare light sensors which establishes a reflectance level of the reflective element. The circuit produces an output that is a function of light sensed by glare and ambient light sensors. The circuit compares an output of a charge accumulation device with a reference, and the circuit selectively connects the glare sensor and the ambient light sensor with the charge accumulation device. The mirror system may include a display operable to project light through the reflective element and may control the intensity of the display as a function of the glare light and ambient light.
