What's New & Noteworthy in Spectacle Lenses

By Andrew Karp
Interest in lenses that filter blue light continues to rise, as more consumers become aware of the need to protect their eyes from high-energy visible light. Several companies are fielding new products in this category, including Signet Armorlite, which is introducing the Kodak Total Blue Lens a hybrid of lens material and AR lens coating that provides 100 percent direct UV protection and up to 80 percent filtering of HEV Blue Light while maintaining true color vision. It is available in a variety of Kodak Lens designs. Clear and polarized options accommodate various visual needs in all environments, both indoor and outdoor.
Vision Ease is debuting Clear Blue Filter FSV Lenses. These polycarbonate stock lenses are available in 65mm and 75mm diameter from +4.00 to -8.00 spheres out to -2.00 cylinder. Vision Ease Clear Blue Filter lenses provide 100 percent UV protection (400nm) and filter high-energy blue light in a crystal clear, everyday polycarbonate lens. Filtering properties are built into the lens, not a coating.
Recommended as an upgrade for the consumer looking to protect and maintain eye health, Clear Blue Filter lenses filter
over 3x more blue light than standard polycarbonate lenses at 420nm and 51 percent of high-energy light between 380 and 460nm. And because they’re especially vulnerable, often in-and-outdoors with just a single pair solution, children
can benefit most as 70 percent more high energy light reaches a child’s retina. Clear Blue Filter lenses are the only clear lens in the industry to carry the Skin Cancer Foundation Seal of Approval, which is recommended as an effective UV filter for the eyes and surrounding skin.
BluTech is introducing BluTech Ultra Lenses. Available in polycarbonate, BluTech Ultra offers industry-leading blue light protection in a lighter color that is constant in density regardless of prescription. BluTech Ultra will be available in plano and prescription lenses as well as in BluTech Eyewear, a complete frame and lens solution for adults and children sold exclusively by ClearVision Optical.
Zeiss is showcasing its DuraVision line of premium anti-reflective coatings, which offer superior clarity, durability and cleanability. DuraVision Platinum, DuraVision BlueProtect, and DuraVision Silver. DuraVision BlueProtect have the same
toughness and convenience as DuraVision Platinum, while also providing significant protection against high-energy
blue light exposure from digital devices and other artificial light sources. The goal is to help wearers more comfortably view the world—mitigating the effects of blue light to reduce digital eye strain as well as promote healthier sleep patterns.
In the wearable tech realm, Rochester Optical is offering
Smart GOLD lenses, which feature an anti-reflective coating designed to block harmful blue-violet light emitted by digital devices. Smartphones, tablets, TVs and even LED light bulbs are common sources of blue light, and Augmented Reality
and Virtual Reality smart glasses are the latest source. Close proximity to users’ eyes intensifies the impact, and too much blue light exposure can cause early-onset macular degeneration. Smart GOLD is the only prescription lens optimized for use with smart glasses. Using proprietary digital-free form lens technology, Smart GOLD virtually eliminates distortion, eye fatigue and strain, and provides the best visual acuity in viewing heads-up-displays.
Essilor is offering Smart Blue Filter, a lens treatment designed to help reduce at least 20 percent of harmful blue light from entering the eyes on an aesthetically clear lens. Knowing it can take a long time to introduce new products; Essilor has integrated the Smart Blue Filter feature into the blanks used in the production of select Transitions brand adaptive lenses, Varilux Digital (PAL) and Eyezen+ (enhanced SV) products at no additional cost.
Eyezen+ are the only lenses in the Eyezen brand portfolio to contain the Smart Blue Filter feature. The three Eyezen+ single vision lens designs are only available through independent eyecare professionals. The patient’s age determines which design is suggested for them: Eyezen+ 1 for patients age 18 to 34; Eyezen+ 2 for patients age 35 to 44; Eyezen+ 3 for patients age 45 to 50 (Essilor recommends considering progressive lenses for this group). All three designs help reduce digital eye strain and exposure to harmful blue light which help to meet the needs of patients’ modern lifestyles.

TREND: High Performance Single Vision

Lately, we’re seeing a growing number of high performance single vision lenses being introduced. A good example is Seiko’s Superior SV, an ultra-personalized lens that starts with three unique designs that are prioritized to match the patient’s lifestyle. Once the patient’s ideal visual needs are determined, ECPs can fine-tune the lenses to provide optimal visual correction in the as worn position. Superior SV’s optimized designs align the focal point so the eyes focus comfortably at the required distance. The patient’s Rx is also aligned to the position-of-wear using the pantoscopic tilt,
frame front angle and vertex distance.
These additional parameters properly align the lenses for maximum visual acuity while wearing the frame in a natural position. Advanced Aspheric Interest in lenses that filter blue light continues to rise, as more consumers
become aware of the need to protect their eyes from high-energy visible light.
Compensation further adjusts the freeform back surface power of the lens for optimum performance in the as-worn position, and virtually eliminates marginal astigmatism and power error caused by variations in eye rotation,pantoscopic tilt and vertex distance.
With Superior SV it is possible to create an almost infinite  number of optimized designs incorporating the patient’s unique data, according to Seiko. The result is precise and stable vision out to the periphery, and extraordinary optical
clarity even with high cylinders and prismatic corrections, the company said.
Hoya is fielding three new lens designs intended specially for new media use: Hoya iD Space, iD Screen, iD Zoom.
Hoya’s exclusive indoor solution is tailored to individual working and wearing conditions.
Rochester Optical is focusing on outdoor vision needs with its new PolyShade85 polycarbonate sun lenses, the darkest
finished and semi-finished single vision sun blanks on the market, according to Rochester Optical. The gray tint is embedded in the polycarbonate substrate and completely eliminates the hassle of tinting for an optical lab or eye care professional.
PolyShade85 lenses feature an average of 15 percent light transmission and provide the most practical single
vision sun lens solution. Available in +4.00D sphere with up to -3.00D cylinder and -6.00D sphere with up to
-4.00D cylinder, PolyShade85 covers a wide prescription range.
Zeiss DriveSafe lenses, as the name infers, are meant specifically for driving. They feature an optimized design plus a special AR coating that offer wearers a precision lens for everyday use with special features to enable
a better and safer driving experience. The benefits of DriveSafe include a more relaxed feeling in low-light or bad weather conditions, reduced discomfort glare for drivers who are frequently irritated by oncoming headlights and, for progressive lens wearers, optimum vision comfort when looking at the road, dashboard and the rear-view side mirrors.
Another new approach to progressive lenses is the Contour Lens with ADT (Adaptive Design Technology) from EGMA and Ocuco. Created with Ocuco’s premium lens design software, Contour lenses combine the latest digital freeform designs with advanced fitting technology to provide patients with excellent progressive lenses. Developed by the same team responsible for Innovations, the optical industry’s leading lab management system; Contour’s Adaptive Design Technology (ADT) provides an interface that assesses active patient feedback to determine their ideal lens design. The process takes less than three minutes and includes lens treatments, accessory and additional pair suggestions to support the eyecare professional’s recommendations.
OptiSource International is introducing plano polarized lenses with AR backside coating. Three different materials are available: TAC (Tri Acetate Cellulose), polycarbonate, standard plastic; nine different colors: G15, gray, brown, gradient-brown and gray, silver mirror-brown and gray, dark-copper and gray; three base curves: 4, 6 and 8.
A new entry in the photochromic lens category is Hoya Sensity. The lenses feature Stabilight Technology which ensures Sensity lenses perform consistently in all climates, all seasons and all circumstances. Not only do they darken to an attractive category 3 sun lens tint faster than ever before, they also quickly fade back to full clarity as soon as the ambient light intensity diminishes. During these rapid transitions, total UV protection remains in place. As a result, Sensity provides ultimate user convenience as well as the best protection, the company said.
