  • “The machines have done just what we needed. We have done all kinds of jobs, single vision, flat top bifocals, progressive, rimless, CR-39, polycarbonate, and even lenses with AR coats. We have done everything except for wrap sunglasses, and the Excelon is very accurate, especially with size. Coburn’s Excelon system is a good value as well. Even with the lower priced machines I chose, the features are there for the money. You can get everything you need for a good price.”
