Same features of the 15TH model but in this version with the best photochromic lenses of the world: those in NXT®. NXT® lenses improve contrast even in dark conditions, visual acuity and depth perception while providing unprecedented eye protection. They are produced in France by Essilor Sun Solution and are guaranteed unbreakable for life. Unlike most standard photochromic lenses, NXT® lenses are fused into the mass of the polymer itself in a very complex manufacturing process, making it more durable and clearly optically superior to most competitors. Their semi-rigid molecular properties guarantee unique light management and unparalleled eye protection from sunlight and the elements. But let’s see in detail the main technical characteristics of these amazing lenses guaranteed to be the best ever in the cycling scene. DURABILITY: They are indestructible. Unlike the polycarbonates used in all photochromic lenses which are rigid, NXT® lenses are a “resinous” and almost “rubbery” material that bends. Impossible to break them. Simply unlike all the others, these do not break. OPTICAL QUALITY: They have a much lower internal stress and chromatic dispersion compared to classic polycarbonates (chromatic aberration 1.5 times lower than polymers) and therefore sharper images and higher definition. The optical quality of NXT® lenses is close to that of mineral glass. Crystal clear images. Perfect vision. RESISTANCE TO SOLVENTS: NXT® resists the effect of Acetone. It is not attacked by chemicals or solvents such as methyl alcohol. VARIATION OF LIGHT TRANSMITTANCE: Photochromic lenses made of NXT® have the widest Light Transmittance Variation available today in the sport panorama. They range from Category 0 (Lt. 80%) to Category 3 (Lt. 17%) covering four categories of brightness. Impossible to do any better. The variation in the degree of darkening is therefore 63%. Very high. REACTION TIME: Very fast. At an average temperature of 23 °, NXT® lenses change color going from clear to totally smoked in less than 20 seconds. Very technical model particularly suitable for those who practice cycling at a very high level.
