Persona Camber lenses combine complex curves on both surfaces of the lens to provide excellent vision correction.

A decorative image

Each Persona 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 well-suited to its function.

This new front surface innovation provides benefits to wearers in both the distance and near zones. Wearers enjoy noticeably increased acuity in the periphery of the distance zone, as well as a reading area that is more comfortable and easier to find with the eye.

Benefits

  • Premium digital lens with high optical performance and expansive Rx range
  • Significantly improved reading zone
  • Extended peripheral vision
  • Better cosmetics (thinner) on some prescriptions
  • Advanced digital back surface

Compare front surfaces

Most digital progressive lenses are processed from a single vision lens blank, which has just one base curve from top to bottom.

In this case, the base curve in the reading area is not ideal, and oblique astigmatism results. The Persona Camber lens blank has a patented, continuously increasing base curve, ideal for the increasing power profile of digital progressive lenses.

A unique conbination of complex curves

When the unique front surface is combined with a sophisticated backside digital design, both surfaces work together to become the Persona Camber finished lens.

The design may be further enhanced by a complete set of individualization parameters to comprehensively customize the lens for each patient.
