Abstract

A process and an apparatus are used for making spectacle lenses from plastic material. The spectacle lenses are worked by working plastic material blanks as a function of data representing the surface of the finished spectacle lens as well as work process parameters. The plastic material blanks are worked in one of a plurality of de-centralized units. For individualized spectacle lenses the data are computed in a central unit as first data and are transmitted to the decentralized unit, and for non-individualized spectacle lenses the data are read out of a first memory in the decentralized unit.
