Abstract
A lens cleaning and polishing method utilizes a stretcher frame mounting a soft pliable lens cleaning and polishing cloth. A hand held suction handle is used to hold one side of a contact lens against the cloth. When the concave side is held against the cloth, the cloth is tented with the finger of the user or a similar shaped object to have the cloth conform to the concave surface. When the convex surface is to be polished, it is placed directly against the cloth and pressure applied. In each case, the cloth covers a substantial portion of the curved surface. The cloth is wetted with a polishing cleaning material and the lens is rubbed with respect to the cloth in order to polish and clean the lens rapidly and efficiently in a hand operation.
Claims4
A method of cleaning and/or polishing a contact lens having a convex surface and a concave surface, said method comprising,
- holding said convex surface of said lens with a suction gripping holder,
- tenting a soft, yieldable cloth stretched substantially flat in a frame by applying point pressure to one side thereof to provide a convex polishing surface for polishing said lens,
- and rubbing said concave lens surface with respect to said convex polishing surface after first applying a polishing material and thereby polishing said concave lens surface.
A method of cleaning and polishing a contact lens having a convex surface and an opposed concave surface comprising,
- holding said concave surface of said lens with a suction gripping holder,
- tenting a soft, yieldable cloth stretched substantially flat in a frame by moving said convex surface of said lens into said cloth to tent said cloth,
- and rubbing said tented cloth with respect to said convex surface to clean and/or polish said surface.
