ABSTRACT:
A diving mask comprising a supporting member for sealing engagement with the face of the user, a lens mounted in the supporting member near the eyes of the user to provide a low volume mask, a major portion of the lens being curved so that apparent magnification of images underwater is less than that observed through a conventional flat lens plate, certain portions of the lens being further curved to eliminate or mitigate pincushion-type distortion.
