1. A reduced ultraviolet radiation transmitting, electro-optic rearview mirror assembly comprising:

  • first and second spaced, optically transparent elements mounted in a mirror case, said elements each having front and rear surfaces and defining a space between the rear surface of said first element and the front surface of said second element;

    an electro-optic medium confined in said space whose light transmittance is variable upon the application of an electric field thereto;

    means for applying an electric field to said electro-optic medium to cause variation in the light transmittance of said medium;

    a reflective coating on one surface of said second element adapted to reflect light incident thereon through said first element and said electro-optic medium; and

    ultraviolet radiation reducing means incorporated in said assembly for reducing ultraviolet radiation degradation of said electro-optic medium in said assembly; and

    spectrally selective absorbing means for absorbing more light in those regions of the visible spectrum from about 560 nanometers to about 780 nanometers than is absorbed in those regions of the visible spectrum from about 400 nanometers to about 560 nanometers.
