Abstract

The invention relates to an installation for the machining of the edges of spectacle lenses, comprising at least one CNC-controlled processing machine (1) for machining a spectacle lens, at least one device (3, 4) for determining the optical values, the optical focus, the axis position of a cylindrical or prismatic polish, the position of the near portion and/or the position of a progression channel of a spectacle lens (6) that is configured as a continuous vision lens. The installation also comprises at least one handling device (9) for removing blanks (6) from a conveyer device (8), for inserting a blank into the device, for removing said blank from said device, for introducing a blank into a respective processing machine, for removing a finished machined spectacle lens from the respective processing machine (1) and for replacing said lens on the conveyer device (8).
