Julbo, the sport glasses specialist stands out of the crowd with its photochromic sunglasses whose shade changes automatically depending on the ambient light. And amongst the various models on the brochure, the Julbo Cameleon sunglasses might be the most outstanding and advanced ones. Indeed, the Cameleon Julbo are able to switch from a level 2 protection rating to a level 4 in mere seconds. The Cameleon glass is therefore perfectly suited for a use on glacier and high mountains, even more so on frames fitted with covering side protections: they are almost as effective as a ski mask. Finally, the Cameleon sunglasses are polarizing for an impeccable anti-blend effect and a better vision on frozen and snowy grounds. With the Julbo Cameleon glasses, high-mountain has never been so comfortable.
