An electrochromic antiglare mirror

摘要

An electrochromic antiglare mirror includes a surrounding light sensor (10) for detecting quantity of light surrounding a vehicle and a rear light sensor (12) for detecting quantity of light in the rear of the vehicle. An amount of coloration is changed in accordance with quantities of light detected by these light sensors. An optical filter (77,79) of a fixed light transmittance is provided in front of a light receiving surface of either one or both of these light sensors for decreasing quantity of light incident to said light sensor or sensors. <IMAGE>
