Abstract
A one-piece protective face shield intended primarily for use by health care professionals to reduce the transmission of infectious diseases carried by viral and bacterial emissions from the noses and throats of afflicted patients. The protective face shield comprises a generally flat semi-rigid transparent sheet which may be bent into a semi-cylindrical face-covering shape and suspended from the bows of the frames of the eyeglasses of the user. A pair of integral bow-engaging clips are provided adjacent to the top end edges of the transparent sheet. The transparent sheet clipped to the eyeglass bows is closely spaced from the user's face and forms a barrier to the transmission of disease causing organisms.
