Abstract
A cover for use in connection with a mirror of a vehicle is provided. The cover is provided with a lens having an electrically activatable material. The lens is positioned in front of the vehicle mirror. The electrically activatable material prevents the reflectivity of visible light off the mirror of the vehicle when the electrically activatable material is set to a light inhibiting state. A coupling device electrically couples the electrically activatable material to an electrical power source. An actuation device is adapted to set the electrically activatable material of the lens to the light inhibiting state in response to user operation such that the lens prevents the reflectivity of visible light off the mirror to reduce the observability of the vehicle mirror.
