Synergy of front and back surfaces

CamberTM Technology combines complex surfaces on both sides of the lens to provide excellent vision correction. The unique variable base curve on the front surface of the specially designed lens blank allows expanded reading zones and improved peripheral vision. When combined with a back surface design using Digital Ray-Path®, both surfaces work together to accommodate an expanded Rx Range. These offer better cosmetics for many prescriptions, and yield user-preferred near vision and performance.

Camber™ is an innovative new lens technologythat combines complex curves on both sides ofthe lens to provide excellent vision correction.


Free-form personalized progressive addition lens

Digital Ray-Path® is the most advanced technology available to make digital lenses. The important difference appears when calculating the back surface of the lens. Instead of using a pure geometrical method, Digital Ray-Path® technology is based on an advanced three-dimensional calculation model that takes into account the actual position of the lens and the natural movements of the human eye. The result of this innovative calculation method is a progressive lens that is personalized and provides better vision in all zones of the lens.

Digital Ray-Path® takes into account the progressive design model. Lenses are personalized according to individual demands of each wearer.


Free-form basic progressive addition lens

Surface Power® is our entry-level digital surfacing technology. Progressive lenses made with this technology have the progressive surface on the back side of the lens, and a simple curve, typically a sphere, on the front side. The progressive surface is calculated using a pure geometrical method that produces lenses with similar optical performance as conventional progressive lenses, but with the advantages of the digital process, like flexible designs, variable corridor lengths and insets.

Surface Power® progressive designs transfer the progressive design to the back surface of the lens to allow free-form processing.


Smart Add technology allows the eyes to be relaxed when viewing screen displays

Smart Add technology improves the patient’s visual experience when using digital devices. This technology assists with changes in focus at different working distances in a more agile and accurate way when the patient is working or reading simultaneously with different screens.
