<p>The invention relates to a lens retaining device for retaining a raw lens in a processing machine. Said processing machine has a tool mount for immobilizing the lens retaining device in a processing tool, and a workpiece mount for receiving a raw lens to be processed. The workpiece mount has a curved surface and is connected to the tool mount. An air channel extends from the tool mount to the curved surface of the workpiece mount. Furthermore, the workpiece mount has an adhesion element which at least to some extent forms the curved surface, wherein the adhesion element has adhesive properties on the curved surface. Furthermore, the invention relates to a method for processing raw lenses with such a retaining device, wherein at least one processing step is executed by retaining the raw lens on the retaining device by means of the adhesion element and by generating a vacuum, and at least one processing step is executed by retaining the raw lens solely by means of the adhesion element.</p> |
