Abstract
A device for controlling the thickness of a contact lens produced on an automatic and computerized numerically controlled (CNC) lathe is disclosed. A sensor control device is incorporated on a lens lathing machine for engaging the front surface of a lens button upon which the convex surface of the contact lens is to be machine lathed. Immediately upon contact between the sensor and the front surface, the sensor provides for breaking an electrical circuit in the lathe controller providing for automatic position registration of the lens button front surface relative to the cutting tool and its pivot point, and a lens of desired center thickness and power curve radius is subsequently generated. Close tolerances and high repeatability are domonstrated in contact lenses lathed generated by these principles.
