Digital FreeForm surfacing equipment has dramatically improved the quality of each lens produced. This applies to conventional front molded progressives, Flat-Tops and Single Visions as well as back-sided Free Form progressives.

A conventional lab has somewhere in the neighborhood of 2,000 laps representing each and every power ground on the back side of a lens. These laps have a tolerance of a tenth of a diopter so one could easily err a typical Rx to 0.2 diopters.

Digital FreeForm equipment has no need for these laps or the labor required to properly pick them or the care to make sure they do not have imperfections that will be transmitted to the Rx. Digital FreeForm generators can cut curves to one one hundredth of a diopter. There are no more laps to pick. The inherent rejects and the labor costs are gone.
