  • Patent number: 4126345
    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.
