A device for placing a contact lens in and recovering it from the human eye comprises an oval loop adapted to be placed against the eyelids and to hold them open against blinking. A handle is provided at one end to facilitate manipulating the loop. A resilient wire filament extends from one end of the loop to the center and it carries a knob or a suction cup offset outwardly from the plane of the loop. The knob is adapted with the aid of a wetting agent to support a lens to be placed in the eye. The suction cup is used when it is desired to recover a lens from the eye. Alternatively, the suction cup may be supported directly on the knob. In either case, the knob or suction cup is moved toward the eye with a finger against the resilient tension of the wire filament until either the lens contacts the eye ball or the suction cup contacts a lens in the eye, whereupon it is released leaving the lens in the eye or removing it from the eye as the case may be. When blinking is not a problem, a simplified form of the invention is the form of a bent rod having a handle at one end and a knob or suction cup at the other end.
