  • Patent number: 4955394
    Abstract: A full-face shield having spectacle openings which mate with the rims of eyeglass spectacles is disclosed. The shield is a continuous lightweight plastic shield which has two eye socket openings which form a press fit about the external rim of the spectacles. The shield is thus held in place by its fit upon the spectacles which are then worn by a person desiring to use the shield. The shield is generally disposable when contaminated but can be sterilized and is readily removed from the spectacles, which are usually cleaned before having another fresh shield attached to them.
