ImpactX™ lenses are guaranteed unbreakable for life.

Getting dark from low to high light transmission within a few seconds and reaching a custom color from an initial clear state, ImpactX™ unbreakable lenses 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.

* Luminous Transmittance: 8% – 48%
