ImpactX® lenses are photochromic. This means they get dark from low to high light transmission within few seconds and reaching a custom color from an initial clear state. They enhance contrast, improve visual acuity and depth perception. 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.
