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.
