Inspired by Nature

DLS Camber Lens Series is a new family of lenses calculated by Camber technology, which combines complex curves on both surfaces of the lens to provide excellent vision correction.

The unique, continuously changing surface curvature of the specially designed lens blank provides an expanded reading zone with improved peripheral vision. When combined with a renovated state-of-the-art back surface digital design, both surfaces work together in perfect harmony to accommodate an expanded Rx range, offer better cosmetics (flatter) for many prescriptions, and yield wearer-preferred near vision performance.

THE ORIGIN OF CAMBER TECHNOLOGY

Camber technology was born from a simple question: How can we combine the best features of both conventional and digitally surfaced progressive lenses, and minimize each one’s limitations? Camber technology is the answer to this question, solving the challenge by unifying traditional optical principals with today’s digital possibilities.

THE CAMBER BLANK

The Camber lens blank has a unique front surface with a variable base curve, which means the power of the front surface increases continuously from top to bottom. This provides the ideal base curve for all visual areas while reducing oblique aberrations in the lens. Thanks to the unique function of its front surface, all DLS Camber finished lenses offer unbeatable vision quality at any distance, especially in the near zone.

DLS CAMBER IS PREFERRED

In a recent clinical trial, wearers compared lenses made from Camber lens blanks to lenses of the same digital design made from spherical lens blanks. The results of the trial show that 83% of wearers adapted more easily to lenses made from Camber blanks. In addition, all wearers found the near zone of the DLS Camber lenses to be equal to or easier to find than the standard lenses. Overall, wearers preferred the DLS Camber lenses 2 to 1.

UNBEATABLE NEAR VISION

The impact of the Camber blank is most significant in the near vision zone. The near visual field is wider and offers better visual acuity. Clinical trials have shown that progressive lenses made with Camber technology are superior to the same design produced with regular spherical blanks. Wearers reported better vision quality and improved levels of comfort while reading with DLS Camber lenses.

Optimized Optics

Better Cosmetics

Digital progressive lenses produced using spherical blanks not only have optical issues, but cosmetic issues as well. The diagram below compares the curvature profiles of two lenses with the same prescriptions: the left is processed using a spherical lens blank and the right is processed using a Camber lens blank. With Camber technology, it is possible to produce plus progressive lenses from flatter and better-looking base curves.

Flexible Options

Wide Availability: Camber blanks are available in a wide range of materials, coatings and base curves, allowing the ECP more prescribing options. Wide Product Range: the DLS Camber lens series provides many design options to make sure ECP’s and doctors can prescribe the right lens according to the unique wearer’s lifestyle

Optimized Optics For All Distances

It is well known that there is an ideal base curve for each power, one which minimizes oblique aberrations and maximizes visual acuity. Most digital lenses are made from a spherical or single vision lens blank, which offers only one base curve across the entire lens.

The Camber blank is different because the base curve on the front surface continually increases from top to bottom, providing a lens with the appropriate base curve for distance, intermediate, and near powers. Wearers enjoy noticeably increased visual acuity for all distances.
