Abstract: A method of making a mirror substrate for an interior rearview mirror assembly for a vehicle includes providing a glass substrate having a generally planar front surface, a generally planar rear surface and a circumferential perimeter edge about a periphery of said glass substrate and extending between the front and rear surfaces. A grinding wheel is moved around the periphery of a front perimeter portion of the glass substrate while rotating the grinding wheel to establish a ground generally rounded surface about and around the glass substrate periphery. A polishing wheel is moved around the glass substrate periphery while rotating the polishing wheel to establish a polished generally rounded surface about and around the glass substrate periphery. The polished generally rounded surface provides a smooth transition between the generally planar front surface of the glass substrate and a rear portion of the circumferential perimeter edge of the glass substrate.

Abstract: An interior rearview mirror assembly includes a mirror casing and a prismatic reflective element. The mirror casing is a unitarily molded mirror casing having at least one attachment surface. The prismatic reflective element includes a glass substrate having a front surface and a rear surface and a perimeter edge about a periphery of the glass substrate. A mirror reflector is established at the rear surface of the glass substrate. The perimeter edge of said glass substrate has a generally rounded surface disposed between the front surface and the mirror casing. The prismatic reflective element is attached at the attachment surface of the mirror casing. The perimeter edge of the glass substrate is exposed to and is viewable by the driver of the vehicle when the interior rearview mirror assembly is normally mounted in the vehicle.
