Abstract
The peripheral edge of an ophthalmic lens is maintained in contact with a bevelling or grooving wheel while being rotated about an axis of the lens parallel to the axis of the bevelling wheel whereby a bevel or groove is formed in said peripheral edge. The ophthalmic lens is capable of relative axial displacement relative to said bevelling wheel. By way of a force or displacement sensor, the relative axial position of the ophthalmic lens with respect to the bevelling wheel can be made subject to the axial component of reaction forces generated between the lens and the bevelling wheel in their mutual contact zone.
