The Maxx Major provides you with a matte finish frame with inlaid rubber ear and nose pieces make these no-slip frames great for all sorts of activities. And, like almost every pair of Maxx HD Sunglasses, the Maxx Major is made from TR90. Style and function all in one! High Definition lenses enhance contrast by reducing the scattered blue light that causes objects to appear “flat” against backgrounds. Contrast is improved so objects appear more sharply defined. Colors are bright and vibrant. Glare is virtually eliminated, allowing your eyes to relax and see everything remarkably crisp and clear. The HD lens cuts through haze and glare for optimum visual clarity, even at a distance. Sharpens contrast while maintaining a natural, no-distorted color balance. Includes a lifetime warranty from the manufacturer Maxx Eyewear against frame breakage.
