1. A sun visor assembly for a vehicle, said sun visor assembly comprising:

  • a front transparent glass substrate having first and second surfaces;

    a rear transparent glass substrate having third and fourth surfaces;

    wherein, when said sun visor assembly is disposed in a vehicle and in a use position, said front transparent glass substrate is closer to a driver of the vehicle than said rear transparent glass substrate;

    an electro-optic medium sandwiched between said second surface of said front glass substrate and said third surface of said rear glass substrate, wherein light transmission through said electro-optic medium is electrically variable;

    a partially light-reflective and partially light-transmissive mirror reflector established at a vanity mirror region of one of (i) said first surface of said front glass substrate and (ii) said second surface of said front glass substrate;

    wherein said front glass substrate comprises an exposed rounded perimeter edge, and wherein said front glass substrate extends beyond said rear glass substrate so as to provide an overhang region about the periphery of said rear glass substrate;

    wherein, when not electrically powered, said electro-optic medium is substantially transparent, and when electrically powered, said electro-optic medium is darkened so as to have reduced light transmission; and

    wherein, when said electro-optic medium behind said mirror reflector is darkened and when said sun visor assembly is in said use position, said mirror reflector at said vanity mirror region is usable as a vanity mirror by a user of said sun visor assembly.
