Digital Progressive Lenses
What are the advantages
of digital surfacing?
Digital surfacing technology has been a real revolution in the optical industry. This lens production technology allows the optical lab to generate and polish a complex surface on the back side that is specifically designed for each lens. With this new production method, the lens is processed from a molded blank that has a spherical front surface. The progressive design, combined with the prescription, is processed on the back surface of the lens.
The main advantage offered by this technology is the ability to produce personalized lenses. The lens design becomes unique, according to the prescription, material, frame and even the visual preferences selected by each wearer.
What makes some
digital lenses better?
The term “digital lens” applies to any lens made with digital surfacing technology. But in order to achieve optical performance superior to that of conventional progressives, the lens has to be calculated using an advanced lens design technology. The digital surface has to be computed in a way that uses the wearer’s individual information to provide better vision, on every point of the lens, for that specific person. And this is exactly what
Digital Ray-Path® does.
