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.
