ABSTRACT:
A removable protective cover and blackout for a lens of a face and breathing mask. The device includes a flexible fabric sheet similar in size and shape to that of a transparent viewing lens of the mask and having an elastic band sewn to the perimeter of the sheet forming a gathered elastic hem sized to fit around the lens frame of the mask. When so positioned, the main central portion of the fabric sheet is against or immediately adjacent the outer surface of the viewing lens. The fabric material for the sheet may be either totally or partially light occlusive and may also include a central aperture in alignment with a connector in the viewing lens for connection to an air intake modulator.
