Abstract
Abstract A device for placing and removing of a soft contact lens from the eye utilizing a tip for presenting one side of a soft contact lens in a shape configuration to allow placement on the eye. The tip holds the soft contact lens against the pull of gravity, but releases the lens when the other side of the lens contacts the eye, producing a surface tension. A handle connects to the tip permitting the hand to manipulate the tip and the lens thereupon.
