In an age of rapid technological advancements, Camber Technology has arisen as a response to the next generation of digitally progressive lenses. Complex curves provide excellent vision correction, superior optics as well as cosmetic personalization.
What is Camber Technology?
Camber Technology combines complex curves on both surfaces of the lens. The unique, continuously changing surface curvature of the specially designed lens blank allows expanded reading zones with improved peripheral vision. When combined with a sophisticated back surface digital design, both surfaces work together to accommodate an expanded Rx range, offer better cosmetics (flatter) for many prescriptions, and yield user-preferred near vision performance.
What are Some of the Benefits?
Ideal Base Curve
When the power of a lens is paired with its ideal base curve, the wearer enjoys clearer vision, with minimal oblique astigmatism. For a progressive lens, the distance zone power calls for a flatter base curve, while the near zone power calls for a steeper base curve. However, most digitally surfaced progressive lenses are processed from a single vision lens blank. This means the various powers must share a single base curve, one that may not be ideal for the near zone.
Front Surfaces Innovation
The Camber lens offers an elegant solution that represents the next step in digital progressive lens technology. The Camber lens blank features a variable base curve — a new front surface innovation that provides the optically ideal base curve in all viewing zones.
Each Camber lens blank comes from a section of the “Elephant’s Trunk” curve, creating a unique variable base curve front surface that continually increases in diopter from top to bottom. This improved front surface profile gives each viewing zone a base curve that is optically optimised.
Merging Complex Curves
When the unique front surface is combined with a sophisticated backside digital design, both surfaces work together to become the patented Camber finished lens. The design may be further enhanced by a set of individualisation parameters, such as unique attributes of the frame and wearer preferences, to comprehensively customise the Camber lens for each individual wearer.
Compensation vs. Personalisation
Digital lens design gives optical designers a lot of power to create lenses that are customised to each patient. But when a progressive lens is made from a single vision lens blank, the uniform front curve creates optical problems that lens designers must digitally correct. Rather than focusing every design decision on achieving a fully personalized lens, some of the design power must go toward “compensation correction.”Camber’s new variable base curve technology reduces the need for compensation correction, allowing more digital design power to be used to refine and customize the design for each individual eye.
