COUPLE OF REPLACEMENT PHOTOCHROMIC DCHROM CAT. 1-3 LENSES 832 MODEL
DCHROM Photochromic lenses are lenses which, exposed to UV radiation or sunlight in general, initiate a reversible chemical reaction and darken. Once the irradiation of light disappears, the lenses gradually return to the initial state of transparency. They are made of first quality polycarbonate. This material has 2 very important technical aspects: it significantly reduces the weight of the lens compared to conventional materials, it also represents a safety in case of impact as it will not generate any type of fragments that could damage the eye. These high-tech filters also protect against UV rays, confirming a certainty in the field of protection as well as from the point of view of comfort.
DCHROM lenses are the evolution of the photochromic lens, they start from a slightly darker base than the other photochromic lenses to reach category 3 during maximum work.
