Abstract
The present invention is directed to a method of controlling an edger device, and a machine programmed to edge a lens blank. A lens blank and an edger are provided. The edger device is capable of forming a groove in a peripheral edge of the lens, and forming at least one hole extending from a first major surface of the lens to a second major surface. A CPU is provided, which is operably associated with the edger device for controlling operation of the edger device. Processing instructions are transmitted from the central processing unit to the edger device. The processing instructions comprise: forming a groove in a peripheral edge of a lens blank; and forming at least one hole in the lens blank extending from the first major surface to the second major surface.
