Digital Lens Surfacing Technologies
Digital Surface Technology
“Digital Surface” technology is the level of digital lens manufacturing that only considers a fixed, non-tilted lens and tangential rays – a pure geometric conception of the lens. This technology brings together advanced optical developments and the simplicity of traditional progressive lenses. Manufacturing lenses with this technology does not take into account any special parameter measurements. As a result, the final lens is not optimized for each wearer. The progressive surface is cut digitally on the back of the lens, rather than the front side.
Digital Ray Technology
“Digital Ray” technology incorporates revolutionary “Eye-Lens” imaging models. Lenses are considered in their full complexity and can be virtually at any position with respect to the eyes – they can have prism, pantoscopic tilt, wrapping angel, any shape contour, and can be located at any distance from the eyes. The final image quality is computed by means of this imaging model taking into consideration eye and lens position characteristics. The precision achieved by this technology is so high that the final lens design provides customized power to each eye in every gaze direction. “Digital Ray” technology provides fully optimized and personalized designs for each user, making lenses manufactured with this method the highest quality available on the market.
