If our standard Photochromic lenses are wizard-like, the Super Photochromic is the Archmage of lens transition. Super Photochromic lenses get way darker than before by going from a mildly tinted 40% to an ultra-dark 10% VLT. From rummaging through your toolbox or taking a direct hit of retina-roasting rays, you get the perfect level of shade. The Rayth is a welcome addition to the performance line. They feature an ultra-bold shape with sharp lines and a premium fit. The Rayth is a standard-width frame, made compact top to bottom and uses a flat profile lens which results in a sledgehammer tough look. The details on the Rayth are second to none and it is sure to become your new go-to power adder when it comes to eyewear. Other Rayth features include a modified arm with rubber inserts to prevent wear and hair snags. Furthermore, the Rayth features increased surface area in the rubber nose for more grip on the face. Standard Performance line features include 2mm thick lenses that meet ANSI Z.87 mass impact requirements plus a specific arm, with beveled emblems with Rubberized Hytrel® inserts in the arms and nose. The Quick-Latch side-shield system provides lateral protection from debris and unwanted side light meeting ANSI Z87+ standards with side shields installed.
