Abstract
Apparatus for the positional control of the edge grinding of an ophthalmic lens to a desired peripheral shape is effected by a control computer which processes and stores data representative of a pattern which delineates the peripheral shape of the lens. The data is derived by rotating a linear image sensor about an axis passing through a support for a pattern which delineates the required shape. The sensor generates pixel data which is processed and stored by the control computer for use for selective control of a lens periphery grinder.
