Wonderful World of Lenses

By Andy Karp

 

Each year, we do a round-up of the new fall lineup of lenses that debuted at Vision Expo West in Las Vegas. This fall, two major trends are evident in spectacle lenses. One is lenses that incorporate increasing degrees of personalization based upon the wearer’s prescription and position of wear and frame style. The other is lenses that are designed for specific activities ranging from viewing mobile devices to driving a car to playing golf.

 

ADLENS

A new lens technology that surfaced at Expo is being used in Hemisphere adjustable prescription sunglasses and computer glasses from Adlens. Hemisphere allows dispensers to “dial, set and seal” the wearer’s prescription by adjusting fluid filled lenses in each eye. The instant prescription eyewear can be customized for different activities—prescription suns for outdoor use, clear lenses for intermediate computer vision. Fluid-filled lens technology was originally developed to provide vision correction in less developed countries. In keeping with its philanthropic heritage, Adlens will donate a pair of glasses to someone in the developing world for every pair purchased. The Buy One Give One Program will be coordinated through Vision For a Nation in Rwanda.

 

ESSILOR OF AMERICA

Essilor’s Varilux S Series lenses—a digital portfolio comprised of three unique lens designs: Varilux S Design, Varilux S Fit and Varilux S 4D are backed by Essilor’s proprietary Nanoptix Technology and SynchronEyes Technology. Varilux S 4D lenses include a third technology: 4D Technology.

Nanoptix Technology, with four new pending patents, re-engineers the fundamental structure of the lens during the calculation process to deliver a lens that not only virtually eliminates swim effect but also offers increased stability in motion.

For the first time in progressive design, SynchronEyes Technology uses the prescription from both the left and right eyes to simultaneously calculate the lenses as a pair to ensure the design is built around both eyes working together as one visual system. This allows for better retinal image matching and improved spatial perception. Patients experience expansive vision and edge-to-edge clarity.

The most sophisticated level of advancement in the Varilux S Series is the Varilux S 4D lens exclusively available through ECPs with the Visioffice System. Just as people are right handed or left handed, they also have a leading dominant eye – the eye that reaches the object being viewed first when we change gaze direction. Only 4D Technology factors in the leading dominant eye and other personalized measurements to deliver faster visual reaction time.

 

CARL ZEISS VISION

The Zeiss Progressive Individual 2 is the company’s most advanced customized lens. Zeiss Progressive Individual 2 features new, proprietary EyeFit and CORE technologies that improve visual performance and allow independent eye care professionals to meet the needs of patients more precisely than ever before. EyeFit technology can personalize Zeiss Progressive Individual 2 based on the patient’s visual activity profile, enhancing the near or intermediate/dynamic performance of the lens as needed based on the patient’s visual priorities, while maintaining outstanding all-distance vision performance.  Based on new Zeiss research, CORE (Center of Rotation Evaluation) technology customizes Zeiss Progressive Individual 2 for the patient’s center-of-rotation distance. Based on extensive Zeiss research, CORE technology calculates each wearer’s center of rotation to within 1mm for 99 percent of wearers. Zeiss Progressive Individual 2 also employs the proven personalization approach of the original ZEISS Individual progressive.

 

HOYA
Hoya’s new Sync lens is for patients that use computers, tablets, smartphones and games. If you think about the strains that are put on our eyes at those different developmental stages, there are a lot of unmet patient needs. Hoya now has a solution for ECPs looking for a lens to fit patients looking for a lens to fit their digital lifestyle.

 




ICE-TECH
Thin-Ice is a patented thinning technology, producing a lens that fits the curve of the frame, eliminating cut-out issues and reducing weight by up to a 50 percent. With Thin-Ice, opticians can feel just as confident dispensing to a low powered myope as they can with an 8-base high powered presbyope.

OPTIMA
Optima is expanding its extensive 1.74 high index product line with the addition of a patented product that achieves a sunglass density of 90 percent gray in 30 minutes, compared to the competitor’s 20 percent gray tint. Using new hybrid monomer technology, Optima has created the thinnest, lightest tintable lens on the market. Optima’s extensive base curve availability enables the Tintable 1.74 Spherical SF SV for Free-form to meet patients’ single vision and progressive needs. Base curves range from 1.50 to 10.25.

 

SHAMIR
Shamir introduced a new Freeform lens designed for handheld digital device users, the Shamir InTouch. With an optimized intermediate zone, the tablet or smartphone user is able to properly focus on the device in their hand. Unlike a standard progressive, Shamir InTouch features enhanced visual comfort from 15 to 27 inches, the distance at which digital devices are primarily held. There is also a quicker transition of ADD power in the intermediate zone. This everyday PAL is available in both 15 and 18 mm fitting heights and in CR-39, SuperLite 1.60, SuperLite 1.67, SuperLite 1.74, polycarbonate, and DLC Trivex.

 





TRANSITIONS OPTICAL

Transitions Vantage lenses, the everyday adaptive lenses designed to both darken and polarize upon UV exposure, deliver noticeably crisper, sharper vision, even in the brightest outdoor glare. These lenses not only adapt to changing light but also increase polarization as they darken, optimizing the angle at which light reaches the eyes to help control glare and light scatter. Learn how Transitions Vantage lenses give eyecare professionals the opportunity to offer a new, unique proposition—a product with both variable tint and variable polarization.

 








SIGNET ARMORLITE

PhotoViews photochromic lenses from Signet Armorlite offer fast fade time and full direct UV protection. They are a great photochromic solution for price-conscious patients who want a quality photochromic lens, but cannot afford a premium brand. PhotoViews’ performance is a significant upgrade to previous generation photochromic lenses that are similarly positioned.  Available initially in gray and brown Standard Resin and in finished and semi-finished single vision, flat-top, trifocal and various progressive lens designs including Kodak Progressive Lenses.

 



VISION-EASE LENS

The Thindex line is expanding with the addition of Thindex 1.70 SRC coated SFSV and A SFSV lenses. In addition to advantages over other high-index materials, including comfort, higher ABBE value and durability, the coated lenses now provide convenience and compatibility for backside spin-coat processing. Thindex 1.70 lenses provide a thin, light and durable option for those with mid to stronger prescriptions, giving patients more choice in frame options and a more visually appealing lens. In addition to the 1.70 SRC Coated SFSV and A SFSV lens options, Thindex lenses are also available as 1.70 Uncoated SFSV and A SFSV, Thindex 1.70 A FSVAR and Novella Thindex 1.70 Uncoated PAL.
