Abstract: A device for handling soft contact lenses comprises a pair of resilient pincer arms, each arm having one end mutually interconnected and a free end spaced apart from the other free end. A lens cup is attached to the interconnected arm ends and is shaped for receiving and holding a sfot contact lens therein. The free end of each pincer arm includes a soft tip connected therewith, which extends outwardly therefrom, is constructed of a resilient, flexible material, and has a terminal surface shaped for frictionally engaging an outer surface of a soft contact lens. The arms are interconnected for positioning the tips on opposing sides of the lens when the soft contact lens is positioned in the eye of a wearer, whereby convergence of the arms folds the lens between the tips for removal of the lens from the eye.

Abstract: A kicking shoe is disclosed which comprises wedging means in the toe box for maintaining the toes of a wearer in an upwardly flexed position. The resulting forward flexure of the toes facilitates "locking" of the wearer's ankle, and causes kicking force to be transmitted to a ball through the heads of the metatarsal bones of the foot rather than through the toes. Accordingly, the accuracy and distance of kicking are significantly improved by use of the shoe.
