This technology, while producing light weight and inexpensive lenses, also produces lenses with very poor optical clarity. The distortion created during injection molding is a visible and pervasive artifact of all current performance sunglass lenses and also interferes with the ability to visualize contours and estimate distances. The graphic to the right shows a pair of our competitor's sunglasses bottom and PeakVision65533Sports Performance Eyewear through an optics viewer that displays optical distortion as a rainbow effect. To address the distortion in injection molded polycarbonate lenses, PeakVision65533Sports utilizes a new material called NXT65533 This new material provides clarity equivalent to optical glass at less than 40% of the weight, while offering scratch and shatter resistance far superior to traditional polycarbonate lenses. Additionally, NXT65533offers 100% UV400 protection! Dual Zone PeakVision Sports incorporates two different technologies into a noticeably unique and differentiated lens by integrating multiple color management filters into a sport lens made from a revolutionary new optical polymer. PeakVision Sports developed the patented Dual Zone filtration that utilizes different filters in two zones of a sunglass lens. In the upper zone, neutral density gray filtration eliminates overhead glare from the sun and enhances distance perception. Through precise color and light management technology, PeakVision65533Sport's u
