ABSTRACT:
In a method and apparatus for making a lens for a pair of prescription eyeglasses a lens blank is shaped and finished on one of its major surfaces through the use of a machine controlled by the prescription information and with a new expendable lap being made each time a new lens is wanted. A machine for cutting a lens blank and/or a lap blank is controlled in three axes by a set of point data related to and obtained in response to the input into the control system for the machine or prescription information.
