WLC
Nova Sports lenses from WLC are said to offer vision correction for outdoor activities with superior clarity, high contrast vision, and glare protection. Available in both single vision and progressive lens varieties, the lenses are designed to fit most of the branded sunglasses. Available in base curves of six and eight, the lenses allow frames to retain their intended shape and wrap around the face to give a significantly improved fit. This also allows improved visual comfort as the lens protects the eye from light from more angles in the peripheral zone.
WLC says the advanced sports design ensures optimal precision, comfort and frame balance for sunglasses. The optimised calculations are used to create customised lenses for each wearer to fit a high number of popular sports frames. The compensation power calculations are done by taking into account the frame parameters and the wearer’s individual features as per the facial anatomy. Prescription lenses are possible for both single vision and progressive lenses with different base curves.
Norville
Norville’s Sportor-SV lenses, which can be mounted in high-curve frames, are said to offer high optical performance. These lenses can incorporate changes in the back vertex distance, dihedral angle and pantoscopic tilt, while accommodating many sports frame styles. The same high-definition optics of the single-vision, digital ray path design can be calculated into a plus 8-base wrap, creating a compensated Rx at the central axis of view.
The company says that because the Sportor-SV is available in a large selection of tints, Transitions, polarised and with Norville’s anti-fog coating, the product opens a new field of sports and lifestyle dispensing opportunities. With its waterproof anti-fog performance, increased polycarbonate light transmissions, scratch resistance and excellent impact resistance, Norville’s anti-fog coating is said to be an increasingly popular option for sports activities. Anti-fog is certified with CE EN 168 ‘N’ European optical standards mark for resistance against fog and CE EN 166 ‘K’ mark for resistance against fine particles.
Waterside Laboratories
Waterside Laboratories says the manufacturing process for its UltraThin lenses incorporates software and techniques that allow six and eight base sports lenses to be produced in prescription powers – a modern enhancement offered in the market. With an extended prescription range from +8.00 to -10.00. The lenses are said to increase prescription sun dispensing opportunities and wearers can enjoy performance and thinner lenses in premium sport frames.
Lenstec
According to Lenstec, I-Play Sports Extreme Digital SV and Progressive lenses match the most challenging of sporting demands with a high base curve range to fit wrapped frame styles and digital enhancements to give maximum optical performance over the largest possible area. I-Play lenses are available in a wide range of materials offering impact resistance and have polarised and photochromic options for light management.
The I-Play progressive is said to give a large, extra-wide distance zone for dynamic active vision, a full intermediate and a smaller reading area ideal for referencing maps, scorecards or your wearable tech and digital devices. Lenstec recommends providing face fit parameters to ensure optimal performance. The company adds that its specialist sport glazing lab has the experience and technology to ensure the best possible fit to every frame and can even add vented cut outs to keep sporting patients cool.
Optimum Coatings
Optimum Coatings says dynamic vision is the key to success in outdoor environments and its Optiform Sport lens has been specially optimised for sports and outdoor activities. Optiform Sport is said to provide an extensive distance vision field with a minimum amount of oblique aberration in the periphery.
According to Optimum, this integration offers users a high visual acuity in all gaze directions, providing enjoyable and natural vision. The lens is also said to offer adjusted near vision for a clear view of equipment, such as heart rate monitors, watches or maps, courtesy of a power distribution that has adequate vision for both near and intermediate fields. The lens benefits from Digital Ray-Path technology, which is said to compensate for and minimises oblique aberrations.
Essilor
The SunMax lens from Essilor has been specifically developed to deliver visual performance in a wrap-around frame. Essilor says, lens technology enables aberrations and distortion in high base curves to be eliminated, leaving the wearer with optimal visual performance right to the corners of the lens. The lens combines prismatic compensation to avoid eye strain due to gaze deviation on wrap frames, with optical compensation to eliminate peripheral distortion and power errors.
Tim Precious, managing director at Essilor UK, said: ‘For any athletic or active person, having a pair of snug sunglasses that offers a wide field of vision and stays in place is crucial for their visual and sporting performance. Wrap-around sunglasses with SunMax lenses are a popular choice for playing golf, running, rowing or cycling.’
