Abstract: An application device is configured to clean grinding surfaces in a machine for grinding ophthalmic lenses, the application device including: a central portion having so as to mount the application device in the grinding machine; and a peripheral edge configured to receive an application surface to cooperate with the grinding surface of the grinding wheel so as to clean the grinding surface. It also relates to a cleaning kit including an application device and a cleaning solution, and to a method for cleaning grinding surfaces.

Abstract: An optical-grade surfacing tool (101) is provided with a resilient return element (115) including a plurality of resiliently flexible strips (118) that transversely project from a rigid central mounting (104), each strip (118) having a distal portion (144) that engages by bearing directly upon a petal (134) of a flexible flange (131) that surrounds the rigid mounting (104). The distal portion is curved along a round loop such that the end (145) of each the strip (118) is rotated toward the rigid mounting (104).

Abstract: Optical grade surfacing tool, including: a rigid support (60); an elastically compressible interface (12) attached to the rigid support (60); a flexible pad (13) adapted to be pressed against a surface (71) to be worked, attached to the interface (12) on the opposite side to the rigid support (60); and return spring elements (14) disposed between the rigid support (60) and a peripheral part (12b) of the interface (12); characterized in that the return spring elements (14) include a plurality of pairs of superposed elastically flexible blades (65, 66) that project transversely from the rigid support (60), respectively a first blade (65) having a distal portion cooperating in bearing engagement, through a first face, exclusively with the peripheral part (12b) of the interface (12), and a second blade (66) cooperating in bearing engagement with the first blade (65) via a second face opposite its first face.
