    Abstract: The apparatus comprises a frame which is positioned over the eyes in front of the forehead so that a recessed portion of the frame fits over the bridge of the nose. An arm pivoted on the frame to swing selectively from in front of one eye to the other, with adjustable stop means to limit the extent of motion, has a slot in the end to receive an insertion device which comprises a slotted collar removably fitted into the end of the swinging arm and supporting a spring biased shaft having a small cup thereon which temporarily retains the soft contact lens by surface tension and not by suction. The removing device comprises a multi-pronged tweezer having arms of stainless steel tipped with a small ball of latex and the arms expand or retract in response to finger movement.To insert a soft contact lens, the spring loaded plunger is mounted in the groove of the swinging arm of the centering frame and the soft contact lens is placed on the rubber cup which is wet with a solution.
