A cover plate, gasket, filter plate and retaining spring are held in a cartridge, which is adapted to be inserted into a goggle body. A plurality of ventilating holes on the top and bottom of both the goggle body and the cartridge combine with a plurality of tabs on the cartridge to provide an air flow path which provides improved ventilation for the inside surface of the filter plate and yet prevent objectionable light from entering the interior of the goggle.
