Defender Spare lenses Impactx 2 Laser Black Photochromic
- 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.
- Getting dark from low to high light transmission within 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.
