ABSTRACT
The article examines whether direct surfacing of ophthalmic lenses is better than conventional processing. The steps in conventional processing of lenses include generating through the rough geometry using a milling technique, then fine grinding the surface to final form and readying the surface roughness for polishing and then polishing the surface. Since direct surfacing replaced the fine grinding step in lens processing, it was able to avoid the statistical deviation that occurs during grinding.
