ABSTRACT The invention provides an improved double lens electric face shield for use in combination with a helmet. The invention also provides for goggles having a double lens arrangement therein. In the case of both the goggles and the shield, there is imprinted, on the inner surface of one lens, an electrical circuit in a pattern of generally parallel, horizontal lines, said pattern printed with con- ductive ink capable of generating sufficient heat to ef- fectively de-ice or de-fog the exterior surface of the other lens when the electrical circuit has electrical power running therethrough.
