Rudy Project ImpactX lenses in different colors according to lighting conditions


Rudy Project ImpactX® lenses are made by photochromic particles which provide unique climatic management technology. These high-tech lenses adjust from an almost clear state to a tinted lens within seconds based on the moment's light transmission range.

ImpactX® lenses enhance contrast, even in darker conditions, they will improve visual acuity and depth perception while providing unparalleled eye protection. Unlike other photochromic lenses, ImpactX® lenses are fused in the mass of the polymer itself with a complex manufacturing process making them more resistant to the elements and optically superior.


ImpactX® lenses feature a molecular semi-rigid material to ensure unique light management and unparalleled eye protection from sun rays and atmospheric elements. ImpactX® is a family of patented polyurethane optical polymers originally developed for military and aerospace applications to provide a bulletproof, transparent, and lightweight material capable of superior protection and reliability.

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.


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.
