New Version II - another bomb from our production for all sports activities.Frame made of ultra-light and extremely durable Grilamid TR 90, adjustable beam, maximum UV protection and, as the icing on the cake, HD visors.HD (High Definition Glass) 3F HD eyepieces are the result of a long-term development of optical glasses with an admixture of crystalline calcium fluoride, which have low color dispersion even at high refractive indices and enable better correction of optical aberrations for higher image performance.You will appreciate glasses with fluoride (HD) glasses in difficult lighting conditions - typically bright sunlight, on snow, or against the water surface. While with standard glasses, dark objects on an overlit background are surrounded by more or less colored edges, fluoride glasses significantly suppress this effect.so fine details and correct color rendering will stand out on a dark object.3F - New Version II - a new dimension of vision.
