Columbus optical operates a state of the art CNC surfacing and finishing lab. Modern computer controlled machinery allows a relatively small staff of technicians to produce a large amount of very accurate work in a short time. The computer entry of Rx parameters lens blocking Going green (“wax” blocking medium instead of the old metal allows that contained heavy metals and were harmful to the environment. curve generation
A CNC machine cuts the rough curves of the lens, using instructions from the layout computer. The distance power, astigmatism correction, prism, and thickness of the lens is determined by this step Fine and polish smoothes the lens blank removing the rough finish from the last step and then polishes the surface to optical lens quality. The lens undergoes a surface quality inspection The lens then undergoes a thickness test The scratch
resistant coating is then applied the lens is again inspected for surface quality. The lens then goes to power inspection where all of the power and prism aspects of the Rx are measured by a laser lens inspection device. Lens that pass the power tests are then blocked for “edging”, this is the process that cuts the lens fit the frame chosen by the patient and the dispensing optician. the lens is then hand finished to insure an attractive fit in the frame and assembled The completed pair of eyeglasses then go back to the lens power inspection station for one more check to make sure all of the Rx parameters match the original order.
