Abstract

The invention refers to a polishing tool for optical lenses with at least one polishing pad adaptable at least partially to the shape of a lens surface of said lenses and drivable by means of a drive shaft, said polishing pad having a membrane, wherein said polishing pad can transmit a bearing force of said membrane at least in an orthogonal direction relative to a lens surface. Moreover, the polishing tool comprises a reinforcing member connectable to said membrane, said reinforcing member being dimensionally stable in a parallel direction relative to a surface of said membrane and being flexible and/or pliable in an orthogonal direction relative to the surface of said membrane, wherein at least one pressure pad with a pressure membrane is arranged within said polishing pad, wherein said pressure membrane can be made to bear and/or can be prestressed against said membrane or said reinforcing member in an indirect or in a direct manner.
