Gravel shoots. Dirt flings. Sand flies. When youâ€™re out there in the world, your eyes are the target for a lot of incoming flak. Thatâ€™s why Oakley Polarized eyewear is the toughest in the business. The materials and geometry we use in our lenses and frames pass all American National Standards Institute impact testing requirements, which is the industrial standard for high-mass and high-velocity impact testing (ANSI Z87.1.)
High-Mass Impact Test
In the High-Mass Impact Test, the lens is struck by a 500 gram (1 pound, 1.6 oz.) metal spike dropped from 51.2 inches (4 feet, 3.2 inches). To pass the test, no frame parts or lens fragments may be ejected during impact.
For the High-Velocity Impact Test, a pneumatic cannon shoots a quarter-inch steel shot at 102 miles per hour (156 kmph) at the lens. The test is conducted from three different distances and seven different angles. To pass, the lens cannot flex enough to reach the eye, nor can any frame parts or lens fragments be ejected.
