Abstract
An apparatus for processing edges of ophthalmic lenses with a gripping device for the ophthalmic lens. The gripping device grips the ophthalmic lens in such a manner that the edge to be processed in accessible, with a turning the gripping device with the gripped ophthalmic lens turns about an axis of rotation. A tool is held in a support and is brought into contact with an edge area of the ophthalmic lens to be processed for the processing procedure. The tool is a lathe tool, with the support being conveyed by a control unit in at least one direction during a rotation of the gripping device corresponding to a prescribed shape of the ophthalmic lens.
