A method by which an eye care professional can convey edger information to a remotely located optician having a numerically controlled edger capable of shaping and beveling lenses in which the eye care professional removes the demonstration lenses from frames which the wearer has selected, places the demonstration lenses on a pattern scale and aligns the horizontal axis of the lenses, traces the outline of each of the demonstration lenses on the pattern scale, places the pattern scale into an optical scanning digital data transmitter wherein the patterns of the lenses are converted to digital information, transmitting the digital information to a computer, and generating an output signal by means of the computer to drive a numerically controlled edger to cause the edger to shape and bevel eyeglass lenses to clone the demonstration lenses.
