OPHTHALMIC LENSES

Digitally designed and surfaced free-form lenses continue to proliferate as evidenced by several new arrivals. Hoyalux iD MyStyle from Hoya Vision Care builds further on the success of the company’s iD Free-Form family, the progressive lenses that integrate the unique qualities of front and back surfaces into a single new progressive design. iHoyalux iD MyStyle incorporates all the benefits provided by iD Free-Form Design Technology, such as natural and focused 3D binocular vision at all distances and in all directions, stable image perception in all circumstances, wide, deformation-free field of vision and smooth and natural interaction. Hoya’s iDEA design (Intelligent Design by Extensive Analysis) principle adds a new dimension to the optical correction of presbyopia. In practice, this comprehensive approach and correction optimization guarantee perfect spatial vision in the most literal sense and total support during any activity. The width of its range—millions of different design variants—ensures that Hoyalux iD MyStyle will provide significantly more personalization than any other progressive lens in the Hoyalux iD family, according to Hoya.

Bristol C&D has a new free-form aspheric progressive lens on the market. “With less distortion and sway, and a larger field of vision, optical performance will be greatly enhanced with the Vertex lens,” said Alex Bristol, president of Bristol C&D. Vertex is based on a high quality free-form design and process with an aspheric surface on the back side of the lens. Vertex offers four corridors, 9, 11, 13 and 16mm with a power range from -8.00 to +8.00. Available from 1.499 to 1.74 in hard coat to super-hydrophobic HMC coating plus polycarbonate, polarized, photochromic and Transitions —all in four styles: Active, Standard, Cubicle and Executive.

Pro Fit Optix is debuting “identity” Swiss-design free-form lenses. Identity is a backside optimized progressive design, offering optimal sight in all distances. According to Pro Fit, the design guarantees the highest optical performance with outstanding cosmetics. The company reports that 98 percent of participants in the user acceptance test adapted to the lenses very easily, even first time presbyopes. Identity is available in three corridor lengths and three lifestyle designs: standard, office and outdoor. Pro Fit Optix is also launching OptixCalc lens calculation software that enables labs to manufacture the identity, Upgrade (SV), and Sports (SV Wrap) designs.

Signet Armorlite continues the expansion of Signetek, its Southern California optical lab where the latest computer technologies and processing equipment are used to produce the digitally-created Kodak Unique backside progressive lens. Now, Signetek is expanding into a full-service lab with the addition of finishing services that include edging, mounting and tinting. Look for more finishing services to be introduced as Signetek capabilities increase.

Also new in the PAL arena is Optima’s high-index HyperPro PAL in a thinner, lighter 1.74 material. As one of only several 1.74 PALs currently on the market, HyperPro 1.74 is offered in both regular and short corridor to accommodate all frame styles. According to Optima, its superior aspheric soft design provides an easier transition from distance-intermediate-reading areas, making it the perfect choice for both first time wearers and current progressive patients. The lens is available in bases of 1.50, 2.50, 3.80, 4.80, 6.40, and 8.00 with adds from +0.75 to +3.50 in +0.25 steps.

New from Younger Optics, the Adage progressive lens offers one of the largest combined functional areas of any short progressive. The near zone is wider than in other leading short corridor progressive designs, which wearers will appreciate while reading. This, in addition to the ultra-wide distance region makes this progressive a significant advancement in the field of short progressive lenses. A minimum fitting height of 13mm will allow new progressive wearers to keep using their favorite frames without losing optical performance.

New technology is also being applied to single vision lenses. For example, Seiko Optical Products of America is releasing finished 1.74 MX SuperClean and semi-finished 1.74 MX Hardcoat single-vision lenses. Seiko is positioning the lenses as “a high-performance, affordable alternative to other, more expensive 1.74 lenses.” The lenses feature Seiko’s patented and proven MX aspheric design, which includes a spherical fitting button in the center, and features a factory applied anti-reflective coating with SuperClean, a super-hydrophobic topcoat that protects the lens and makes them easier to keep clean.

The 1.74 semi-finished lenses feature Seiko’s new high-index HDC4 hardcoat, which includes a shock absorbing primer and extra-thick hardcoat. It has an extra-large range that is sufficient for the majority of prescriptions, letting more people than ever experience the benefits of super thin 1.74 lenses.”

Seiko’s full line of 1.74 single-vision lenses also includes 1.74 FSV with Transitions lenses, giving patients a variety of choices in 1.74 product.

The finished 1.74 MX AR lens is available in plus spheres from +2.00 to +6.00 (out to -2.00 cylinder.), and in minus spheres from -2.00 to -10.00, (out to -3.00 cylinder), and in half-diopter steps from -10.50 to -15.00. The semi-finished range is from +10.00 to -15.00, out to a -4.00 cylinder (total power -15.00D).

PHOTOCHROMICS

A couple of lens makers are fielding new photochromics this fall. Augen Optics introduces Augen Parasol Photochromic Lenses, a unique combination of premium Augen High Definition lens design technology and the most advanced photochromic material available today. Made with 1.50 hard resin photochromic material, Augen Parasol lenses get dark exceptionally fast outdoors—comparable to leading photochromics. They provide 100 percent UVA/UVB protection on both front and back lens surfaces. The extra-dark tint rivals the light protection from sun lenses. Plus, Augen Parasol lenses fade more quickly to a barely noticeable tint indoors, the company says.

Transitions Optical is expanding its family of products with the availability of Transitions XTRActive lenses in 1.50. Transitions XTRActive lenses are a new choice for patients looking for an everyday, adaptive lens that offers superior darkness outdoors in all temperatures. Transitions Optical is also partnering with Seiko Optical to launch a new Transitions SOLFX sun lens.

X-Cel Optical together with Transitions Optical is launching a new lens in the sunwear product line with Autumn Gold Transitions SOLFX, a photochromic sun lens specifically designed to enhance contrast and improve clarity of images in cloudy, foggy or very bright outdoor environments. Specifically recommended for hunters, target and skeet shooters and archers, Autumn Gold Transitions SOLFX will help improve visual performance.

Younger Optics is also introducing a new sun lens, NuPolar Trilogy—Visual Armor. The new sun lens provides unparalleled protection and visual acuity by use of NuPolar polarization technology and Trilogy (Trivex) material properties, according to Younger Optics. This patented new development brings together great optics and impact resistance with protection from blinding glare and UV, all in a thin and lightweight lens. NuPolar Trilogy is the ultimate in Rx sunwear. Rx Range: -7.00 to +7.50. Base Curves: 2.25, 4.25, 6.25, 8.25. Colors: True Gray and True Brown.

AR LENSES

Anti-reflective lens technology continues to advance with products such as Essilor’s new Crizal Sapphire lenses with Scotchgard Protector. This latest generation of Crizal offers no-glare performance, scratch resistance and cleanability that surpasses Crizal Avancé lenses with Scotchgard Protector. Essilor’s exclusive Enhanced Light Transmission (ELT) System maximizes light transmission through the lens by further reducing glare and visible reflections. Essilor’s SR Booster layer provides superior scratch resistance and Essilor’s proprietary High Surface Density (HSD) process increases cleanability with a contact angle of 116 degrees.

iCoat has created a new anti-reflective lens treatment called Aura using a proprietary DHC hard coating process and Aura Maximum Transmission (AMT) technology to maximize light transmission and increase visible light to the eyes. Aura ultra premium AR lenses offer advanced visual performance with superior anti-scratch, anti-static and anti-glare properties. Aura lenses virtually eliminate annoying backside reflection, discomforting eyestrain and repel water, oils, dust and smudges. Features include: extreme Bayer hardness for unmatched scratch resistance; super oleophobic properties repel fingerprint smudges, dirt and water; exceptionally impact resistant due to proprietary deposition binding; guaranteed against cracking, crazing, peeling and scratching; ultimate AR protection eliminates glare and eyestrain; and exponentially enhanced visual clarity.
