Electro-optic window assembly

A unitary electro-optic window assembly comprising:

• a window element comprising:
• a first substantially transparent substrate defining a first surface, a second surface, and a first peripheral edge;
• a second substantially transparent substrate defining a third surface, a fourth surface, and a second peripheral edge, wherein the first and second substantially transparent substrates define a cavity therebetween, and wherein the first substantially transparent substrate is vehicle inward relative to the second substantially transparent substrate;
• an electro-optic medium at least partially filling the cavity and configured to reduce light transmissivity of the window element;
• a controller adjacent to the window element and in electrical communication therewith, the controller configured to change a voltage applied to the electro-optic medium to change the light transmissivity of the window element;
• an interface in electrical communication with the controller;
• and
• a transparent dust cover positioned over the first surface of the window element, the controller, and the interface.
