The Domain is our best selling pair of sunglasses for every sport; loved for its stylish design, comfortable fit, light weight, and of course our amazing high definition lens.And, like almost every pair of 2017 Maxx HDSunglasses, the Domainis made from TR90 and includes our lifetime warranty against frame breakage.Available in black, blue, red, or white with HD polarized, or smoke polarized lenses. 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.
