ABSTRACT:
A device for facilitating the insertion and removal of a soft contact lens from a human eye, including a suction cup, a tunnel extension on one side of the suction cup, a vacuum source for applying vacuum through the suction cup to the lens and a collapsible member between the cup and the vacuum source. Upon placement of the suction cup over the lens such that the tunnel extension extends over the edge of the lens, the edge of the lens under the tunnel is caused to lift from the eye when vacuum is applied thereto and the suction created draws the entire lens against the suction cup. The collapsible member between the vacuum source and the suction cup collapses causing the suction cup holding the contact lens to move automatically away from the eye.
