1. A reduced first surface reflectivity electrochromic/electrochemichromic 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 electrochromic/electrochemichromic 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 electrochromic/electrochemichromic 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 electrochromic/electrochemichromic medium; and

    anti-reflective layer means on said front surface of said element for substantially reducing reflection from said front surface of said first element whereby said assembly provides lower total reflectivity and reduced double imaging.
