ABSTRACT:
A tool for the precision processing of the optical surfaces of lenses has an elastic membrane (10), connected to a rigid holder (20), which incorporates a processing segment (11) and a bellows-type segment (12). Together, the membrane (10) and the holder (20) delimit a cavity (15), which is filled with a material (16) that becomes ductile under specific conditions, and which can be induced, at will, to form a flexible or rigid supporting layer for the membrane (10). When the material (16) is in its ductile state and the processing segment (11) contacts the optical surface, the bellows-type segment (12) exerts forces on the ductile material (16) which cause it to press the processing segment (11) against the optical surface, so that the tool retains its shape after the ductile material (16) has become rigid. As this tool can be used to shape any type of optical surface, it is particularly well-suited for the processing of prescription lens eyewear.
