Patent attributes
A rearview mirror assembly for a vehicle includes a mirror casing and a mirror reflective element disposed at the mirror casing. The mirror reflective element includes at least a first glass substrate having a front surface and a rear surface. When the rearview mirror assembly is normally mounted in a vehicle, the front surface is closer than the rear surface to a driver that is normally operating the vehicle. The first glass substrate has a flat central region and a rounded perimeter edge, and the rounded perimeter is exposed to and is viewable by the driver of the vehicle. With the mirror reflective element disposed at the mirror casing, no portion of the mirror casing encompasses the rounded perimeter edge. The rounded perimeter edge has a glare-reducing surface finish.
