Our RWX by NXT® winter technology lens produced by Essilor has got both high-tech and fashion features. Powered by the state-of-the-art photochromic technology, it provides the right level of protection as it adapts to the light environment protecting your eyes from 100% of the UV rays. The innovative winter technology ensures optimal vision on the snow in all weather conditions, solving the typical problem of photochromic lenses which darken at low temperatures even in low light conditions. The RWX by NXT® lens includes fast kinetics such as activation and fading speed: from category S1, when not activated, in environments and weather conditions with low light and less bright snow condition, to category S3, when activated, in bright conditions. In addition to its technical features, the RWX by NXT® lens will also magnify your look! From subtle gloss, while non activated, to intense blue aspect in bright conditions, it brings colour differentiation. Note that this mirror coating contributes to protect from glare and reduce eye fatigue. The oleophobic front-side coating prevents scratches, smudges, fingerprints, dust and water on the external surface of the lens. At last, to keep the lens gloss and neat, it also minimises the risk to damage the colour coating as cleaning is facilitated.
