Rudy Project ImpactX lenses in different colors according to lighting conditions


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 several different colors and with the Laser mirrored coating. 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.

ImpactX® lenses are guaranteed unbreakable for life. Their molecular semi-rigid properties ensure unique light management and unparalleled eye protection from sun rays and atmospheric elements. ImpactX® is a family of patented polyurethane optical polymers, transparent and unbreakable, originally developed for military and aerospace requirements to provide bulletproof, transparent, and lightweight material capable of providing superior protection, reliability and longer lasting performance than polycarbonate.

ImpactX® lenses are 16% lighter than CR-39 and 10% lighter than polycarbonate; they have lower internal stress and chromatic dispersion than polycarbonate, resulting in sharper images, higher definition, reduces "rainbowing', and more visual comfort. The program offers cutting-edge photochromic and polarized technology for unparalleled weather management.


In addition to faster activation, the innovative photochromic pigments specifically developed for the new ImpactX® lenses, incorporated an advanced filter function which scientifically modulates the wavelength of light passing through the lens: by eliminating a portion not perceived by our eyes and optimizing its spectrum, the HDR technology provides extraordinary visual performance. While maximizing the chromatic range, perceived benefits include superior perception, sharper image and unparalleled enhanced contrast definition.
