The automated Mei 641 employs a revolutionary technology that will forever change the way lenses are cut to be assembled into eyeglass frames. With Mei, we now utilize a series of different milling cutters to perfectly shape and bevel the lens edge and surfaces versus the old technology of grinding a lens to shape. Cherry Optical, Inc’s finishing process includes two (soon to be three) automated Mei641 CNC lens milling machines that allow us to handle everything from simple edging jobs to the complexities required of many sport and fashion frame designs. Every lens, no matter the price, gets the same advanced edging treatment at Cherry Optical, Inc.
