Equipped with a patented interchangeable lens system that's ideal for the running trail, golf course, or bike trail, the Threshold Slider sunglass is lightweight and versatile. The lenses are easy to swap thanks to the slider system, which lets you remove each lens with a quick upward motion. The polarized 9-base carbonic Tapered Lens Technology (TLT) design, meanwhile, blocks 99.9 percent of reflective glare while minimizing peripheral exposure to sun, wind, and glare. And wearers will love the Grilamid TR-90 frame, which includes Megol nose and temple pads to ensure a comfortable nonslip performance. Available in a medium/large fit with 16 replacement tints to choose from, the Threshold Slider is backed by Smith's legendary lifetime warranty.
About Smith Optics
Based in Sun Valley, Idaho, Smith Optics, Inc. was founded in 1965 with the creation of the first-ever goggle featuring a sealed thermal lens and breathable vent foam. In the early years, founder Dr. Bob Smith, an orthodontist by trade, made goggles by hand using dental tools, foam, and glue. Before he struck a deal for manufacturing of Smith goggles in the late 60s, Smith would often trade his creations for lift tickets. These early prototypes were usually manufactured by Smith and friends around the kitchen table.
Building on that goggle heritage and extending its expertise, Smith Sport Optics has gone on to set the standard for high-performance eyewear and goggles. Innovations over the years include the Fog-X anti-fog coating, PMT Perforated Membrane Technology lens ventilation system, patented Turbo C.A.M. Constant Air Management system, patented Regulator adjustable lens ventilation system, patented Roll Off's film advance system for motocross, patented ODS (Ocular Docking System) prescription insert, and patented Slider series sunglasses, the most innovative interchangeable lens sunglass available.
Today, Smith Optics has become synonymous with innovative, durable, top-quality products in the eyewear and goggle market. The company is also recognized for its unparalleled team roster, which boasts some of the top names in biking, motocross, skiing, snowboarding, surfing, skateboarding, and wakeboarding. Like many other companies, Smith utilizes team input as a key element of new product introductions. In addition, Smith athletes are actively involved in the development process for performance testing and coloration selection.
