Progressive lenses and single vision lenses
An optical lens that has only one luminosity on a single vision lens and does not have special functions.

A pair of glasses can be used. You can see far away, you can see close, and you can see objects in the middle distance.
Production technology of progressive lenses
In addition to the evolution in design, the production technology of progressive lenses is also constantly improving: the most representative one is the free-form technology. The emergence of free-form surface technology makes the production more flexible and rapid and can realize a more personalized design.
