Its unique front surface has a continuous curvature variation. It is specially designed to increase the reading areas and achieve better optical quality.
Front surface innovation
A single progressive lens has many powers; hence it has many ideal base curves, increasing in diopters from top to bottom. The distance zone power calls for a flatter base curve, while the near zone power calls for a steeper base curve. When a free-form progressive lens is processed from a spherical lens blank, the various powers must share a single base curve, one that may not be ideal for the near zone.
The Camber lens blank features a variable base curve, a front surface innovation that provides the optically ideal base curve in all viewing zones.
Three components in synergy
The innovative lens blank is only the beginning. When the unique front surface is combined with a sophisticated back-side digital design, both surfaces work together to become the Camber finished lens.
Camber lenses have three essential components:
The Camber blank
With variable base curve by Younger Optics, the Camber lens blank improves on the spherical lens blank, by offering a continuously increasing base curve that is better suited for progressive prescriptions.
The Camber Rx design computation by IOT
Created with IOT Digital Ray-Path 2 Technology and Steady Plus Methodology, Camber lens designs are mathematically compensated for peripheral aberrations and include the intelligent use of the wearer’s accommodation to drastically reduced aberrations across the entire field of vision. They also incorporate strict control of mean power to practically eliminate spherical error in lateral areas of the lenses, resulting in improved lateral vision and superior image stability.
The Rx design computation is further enhanced, when desired, by a complete set of individualization parameters that take into consideration the unique attributes of the frame and the preferences of the wearer. The result is a finished lens that is comprehensively customized for each individual patient.
No lens is more advanced
Camber Steady Plus Progressive lenses provide the wearer with an unbeatable visual experience: wide reading zones, improved peripheral vision, extended power range, more aesthetically pleasing lenses, and unbeatable near vision performance.
NEAR ZONE EASIER TO FIND WITH CAMBER LENSES
NEAR VISION QUALITY EQUAL OR BETTER WITH CAMBER LENSES
EASIER ADAPTATION WITH CAMBER LENSES
In a double-blind study, test wearers compared the same progressive design, one of them engineered with Camber technology and the other one without it.
• Test wearers wore each pair of glasses for the duration of one week but were not aware of which lenses they were wearing for the entirety of the study.
• Both pairs of lenses were of identical material and base curve and mounted in the same frame.
• Wearers were surveyed about their experience with the lenses after testing them both.
- Better vision in all zones (compared to spherical lenses).
- Improved reading area. More spacious, easier to find.
- Easier adaptation. Studies show faster adaptation for most wearers.
Variable base curve
Due to the variation of the base curve, the lens is built from the start with a more ideal surface. It provides excellent optical quality at any distance, especially in near vision.
Camber Technology allows the laboratory to select flatter base curves while still giving the patient the curve they need for maximizing their near vision zone.
Personalized free-form progressive lens designed with Camber Technology
IOT Digital Ray-Path 2
Oblique aberrations are minimized more effectively than ever by incorporating the intelligent use of wearers’ accommodation into traditional calculations.
This methodology, patented by IOT, is a technological breakthrough in digital lenses. It provides a strict control of average power in the far distance vision zone and virtually eliminates peripheral spherical power error.
Steady Plus Methodology
Steady Plus allows for more sophisticated control of the medium power distribution to improve performance for midrange and near vision. to achieve a perfectly symmetrical and smooth power distribution.
