ABSTRACT:
A light passing, contact lens inserting tube having an annular lens holder is inserted through a plunger tube in an extended position and into a friction collar freely slidable in a tubular handle mounted fixedly on the plunger tube which is spring urged to a retracted position relative to an eye cup. Then a contact lens is lightly adhered to the holder by wetting fluid, the plunger tube is released to move the lens back into the eye cup, with the tool extending upwardly, and the plunger tube is extended from its retracted position to allow the inserting tube and lens to move by gravity toward the eye to place the lens very gently on the eye. A steady rest on the eye cup engages the cheek to insure that the tool is perpendicular to the eye. The lens inserting tube may be removed and replaced with a lens removing tube with a suction cup flexibly mounted thereon to remove the contact lens from the eye.
In an alternate lens handling tool, a plunger tube is spring urged to a retracted position relative to an eye cup and an annular lens holder is carried by a tubular carrier freely slidable in a cap fitting on one end of the plunger tube. Another alternate lens handling tool has a carrier tube slidable relative to an eye cup and carries an annular lens holder by a tubular bellows.
