ABSTRACT:
A process and apparatus for polishing an optical surface of an ophthalmic lens is provided. The process of the invention comprises the steps of roughing an optical surface of a polycarbonate lens substantially without coolant and passing a polishing wheel of the present invention over the surface of the lens with the use of coolant and then passing the polishing wheel over the surface of the lens substantially without coolant for at least one pass over the portion of the lens edge to be polished. A single abrasive wheel is used for machine polishing of the optical surface of the lens. The wheel is an impregnated wheel of from about 2 to about 60 micron diamond hardness abrasive particles in a concentration of from about 10 to about 200 concentration.
