NEW DCHROM Photochromic lenses are lenses that, when exposed to UV radiation or sunlight in general, start a reversible chemical reaction and darken. Once the light irradiation disappears, the lenses gradually return to the initial state of transparency. They are made of top-quality polycarbonate. This material has 2 very important technical aspects: it considerably reduces the weight of the lens compared to conventional materials, it also represents safety in case of impact as it does not generate any kind 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.
The new 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 in the maximum work phase.
In addition to the remarkable speed of clear dark change, they will surprise you for the remarkable sense of relaxation that they can provide to your eyes, even on days with very strong solar radiation.
The ultra-light and elastic material of the frame is the TR90, a special composition made of Carbon Fiber and Nylon, which effectively increases its resistance to accidental impacts. There is also a significant increase in durability over time. But the most important factor of the TR90 is the weight, it gives 20% more lightness than conventional materials, bringing the total weight to about 50 grams.
The internal view clip with a wide visual range in base 6, is also in TR90, to obtain a consistent duration over time, and to prevent breakages from vibrations and stresses. A clip in base 6 consistently increases the range of powers applicable by your trusted optician.
The measurements of the Clip are: Lens Height: 29mm; Lens length: 44mm; Base Lens: 4.
It is possible to install lenses with gradations in your own optical specialist: maximum spheres +/- 8.00 and cylinder (astigmatism) +/- 2.00.
The nose pads in soft hypoallergenic rubber are adjustable thanks to an internal aluminum core. The fit is excellent for every face appearance.
The temples are equipped with a grip system, in anti-allergy non-slip rubber that allows the elimination of those micro glides on the front, determined by the vibration of the Mountain Bike practice, or by the long stride of those who practice Running.
