ImpactX lenses are made by photochromic particles which provide unique climatic management technology. Getting dark from low to high light transmission within few seconds and tailored to reach a custom color from an initial clear state, ImpactX® lenses are available in 3 different colors and with the Laser mirrored coating ( Black and Laser Black , Red and Laser Red, Laser Brown). ImpactX® lenses enhance contrast , even in darker conditions, they will improve visual acuity and depth perception while providing unparalleled eye protection. Unlike most photochromic standard lenses, ImpactX® lenses are fused in the mass of the polymer itself with a complex manufacturing process, making it more resistant and clearly optically superior to most competitors.
