Abstract: Periscope Swim Goggles are swimmer's goggles with a periscope situated above the water line that projects the view that is ahead of the swimmer through a fiber optic cable to a viewer located on the goggle's eyepiece. Generally, an open-water swimmer using the free style or crawl stroke must occasionally sight on a landmark to swim toward. Periscope Swim Goggles would enable the swimmer to continually swim directly along the desired path without lifting the head for sighting. Conventional swimming goggles are typically comprised of two eyepieces contoured and gasketed for an air-tight fit around each eye socket and an elastic strap that wraps around the head holding the eyepieces tight to the face. In one embodiment of the invention, the periscope is positioned and secured at the back of the head by the elastic strap of the goggles. The fiber optic cable leaves the periscope and follows the elastic strap to the viewer which is mounted to the front of the eyepiece.

Abstract: In a face mask for use in the practice of paint-ball games or other such activities requiring effective shielding of the face, a large unitary lens is applied to an aperture extending from the brow to the chin and from one temple to the other. The lens is secured by a pair of releasable clips that can be quickly manipulated for cleaning or replacement of the lens in a matter of seconds. A semi-conical breath deflector extends behind the lens from the nose bridge to the base of the lens channeling the breath away from the lens and towards ventilating slits in the base of the mask. The slant of the deflector avoids any obstruction of the field of vision such as created by the lens frame of conventional goggles and face masks.
