The invention relates to a polishing tool (100) for polishing a spectacle lens (L) in a surface machining process, which comprises a tool body (110) for being rotatably supported about a rotational axis (RA1). The tool body (110) comprises a polishing surface (130) being outwardly exposed at a first axial end (101) of the tool body (110). Therein, the polishing surface (130) is axially bulged convexly or concavely with respect to the rotational axis (RA1) for polishing an optical surface (L1, L2) of the spectacle lens (L). The tool body (110) further comprises a channel (140) that extends axially through the tool body (110) from an inlet (142) to an outlet (141) to supply the polishing surface (130) with a polishing agent. The inlet (142) is provided at a second axial end (102) being opposite to the first axial end (101) with respect to the rotational axis (RA1). The outlet (141) is provided at the first axial end (101). The polishing surface (130) comprises at least one groove (150) that extends radially away from the outlet (141) to the perimeter of the polishing surface (130) to distribute the polishing agent across the polishing surface (130). The invention also relates to a system (200) and a method for polishing a spectacle lens (L) in a surface machining process with said polishing tool (100).

A device for polishing an optical lens or an optical mirror, using a liquid polishing agent, has a workpiece carrier for establishing at least a first surface of the optical lens or of the optical mirror. The workpiece carrier has a porous and elastic lining for establishing the at least one first surface of the optical lens or of the optical mirror, and the lining is configured as a lining that is permeable for the polishing agent. Furthermore, a method polishes an optical lens or an optical mirror.
