ANSI Z87.1 tested means that the frame and lenses meet or exceed specific safety ratings set by the American National Standards Institute (ANSI), who has developed a certification system for safety eyewear in the US. As an American brand, we test our eyewear to pass a high velocity impact test and a high mass impact test, as dictated by ANSI.
The high velocity impact test demands that the frame and lenses must withstand the impact of a 6,35 mm steel ball fired at 164,6 km/h, while remaining intact. The high mass impact test demands that the frame and lenses must remain intact while withstanding a 500 grams pointed projectile that is dropped down on the eyewear from a height of 127 cm.
