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