PeakVision is known for its patented Dual-Zone Lens Technology. The PeakVision lenses were designed by J-Paul Moore to eliminate distortion within sports optics. It took him over four years to prototype and design the PeakVision dual-zone lens, which he dubbed to be the perfect lens for golf, tennis, biking, and many other sports. AV1 sunglasses are equipped with PeakVision's proprietary Zero-Distortion optics featuring patented Dual-Zone lens technology to deliver the clearest, sharpest vision in both lighting extremes; the bright sky versus the darker turf and terrain below the horizon. AV1 features two zones: - 20 percent neutral-gray upper zone tuned to manage the bright glare from the sun and sky. It combats UV400 rays, enhances long-distance vision, and lessens eye fatigue over your duration of usage. - 60 percent amber lower zone brightens up the contrast of the putting surface. It provides 3X view to the naked eye, for an impeccable read of greens and course. RA Filters Our AV1 sunglasses are equipped with RA filters on the front and backside of the lens, to combat against glare from all angles. It enhances your vision and gives a clearer view.
