While it’s not easy keeping up with the newest lens designs regularly being introduced, here are the latest free-form offerings from the major manufacturers.
Impression FreeSign 3 progressive lenses come in four variations based on lifestyle: Active, for those with sporty lifestyles, provide high image stability at far and medium viewing distances; Allround, for those who participate in various activities, offer comfort for all visual zones; Expert, for patients who need smooth vision at all distances, especially medium distances; and Individual lenses, which are completely customized based on lifestyle using Rodenstock’s DNEye Scanner to accurately measure high and low order aberrations.
Varilux X Series lenses feature Xtend technology, a design calculation that extends the area of vision within arm’s reach, eliminating the need to tilt or angle the head to find “just the right spot,” according to Essilor. Nanoptix technology helps to reduce an “off balance” sensation, and Synchroneyes technology allows for a smoother transition between visual distances. Varilux X Series lenses also incorporate Wavefront Advanced Vision Enhancement (W.A.V.E.) Technology 2 for sharp vision even in low-light conditions.
HOYA’s iD MyStyle 2 lenses accommodate the total needs of a patient, from lifestyle to previous lenses worn. Lenses incorporate Binocular Harmonization Technology (BHT), which treats the right and left prescription as individual components to define the required binocular lens design. The necessary corridor length and progressive power distribution are then calculated, ensuring both eyes receive equal accommodative support. Every iD MyStyle 2 prescription is verified before the lenses are made with HOYA’s Binocular Eye Model and 3D visual acuity simulation.
Optimized for work environments, Unity Via OfficePro lenses automatically calculate near and intermediate distance zones and are available in two working distances — 5 feet and 10 feet — to accommodate all patients’ needs. With maximized near and intermediate zones, Unity Via OfficePro lenses aid in computer work, reading, writing and in meetings. According to VSP Optics, Unity Via OfficePro lenses help to alleviate eye strain, improve ergonomic comfort and provide clarity of digital displays. Unity Via OfficePro lenses are available in CR-39, polycarbonate, Trivex and high index 1.60, 1.67 and 1.74 materials.
The newest addition to Kodak’s Professional Series, Kodak Unique DRO progressive lenses incorporate a full backside progressive design, i-Sync technology to maximize clarity in the peripheral area of the lens and Vision First Design technology to increase prescription accuracy with a smooth gradation of power across the lens surface. Lenses are available in six corridor lengths and more than 60 materials. Dynamic Reading Optimization (DRO) technology maximizes the reading zone to provide comfort during prolonged digital device use. DRO technology also reduces oblique astigmatic errors in the reading area, allowing eyes to focus for longer periods of time.
To address the everyday needs of wearers, Shamir released Autograph II+ lenses that combine two digital technologies: Close-Up, which adjusts the reading zone inset of the lens to provide increased comfort for reading and intermediate viewing, and Natural Posture, a technology that controls the location of the near viewing zone as a function of a plus or minus prescription, which affects both head position and posture. Autograph II+ lenses offer wide viewing fields and a personalized prescription based on the selected frame with the company’s As-Worn Technology. Lenses are available in both variable and fixed designs, including 11mm, 13mm, 15mm and 18mm fitting heights. They are offered in 1.5 hard resin, DLC Trivex, 1.56, NXT, SuperLite 1.60, SuperLite 1.67 and SuperLite 1.74 materials.
Luminance Design technology provides better vision in low-light conditions in ZEISS DriveSafe lenses, available for both single vision and progressive lens wearers. DuraVision DriveSafe coating reduces glare by reflecting the most harmful wavelengths from LED and Xenon headlights, and progressive lenses incorporate optimized distance and intermediate viewing zones to reduce the need for horizontal head movement while driving.
