polishing 

The final stage in the surfacing process in which the lens is made smooth and provides regular (instead of random) transmission and specular (instead of diffuse) reflection. It is accomplished by rubbing the lens to and fro over a tool covered with felt cloth or plastic sheet or with pitch (which produces the best results) sprayed with water containing finely powdered cerium oxide or rouge. The curvatures of the lens remain unaltered in this procedure. Polishing of spectacle frames is referred to as buffing or mop polishing or barreling (if the polishing is done using a drum). See cerium oxide; rouge; smoothing; surfacing.
