Thanks, Chuck. Every pair of new eyeglasses frame has the filler lenses. Lab workers need to put this "Filler lens" as the model in the lens edging machine, and then put the real lens in the machine. The machine will just work and "copy" the shape and size of the filler lens, then you got the exact lens for fit into your frame. Of course the lab worker need to make sure the right angle is placed to ensure the optical center of the lens.
Different machine has different speed and accuracy. Essilor edging maching is very good alternative. Normally, fitting one pair of eyeglasses, including the grinding and fitting, takes from 10-20 minites at most. If using Essilor machine, it is 10 minutes only, with accuracy.
