'''Z87:''' ANSI certified for regular impact. For safety eyewear to pass the basic Z87 standard, it must pass the ''Drop Ball Impact Test''. This test involves a steel ball (that is one inch in diameter and weighing roughly 2.4oz) dropped from a test height of 50 inches. For eyewear to pass, the lens and frames must remain intact. Eyewear rated at Z87+ are better, having passed the Drop Ball Impact Test as well as a High Mass Impact Test, High Velocity Impact Test, and a Penetration Test. | '''Z87:''' ANSI certified for regular impact.
