Eyewear products marked with Z87.1 or Z87+ have passed Test 5.2.1 drop Ball Impact Resistance, Test 6.2.2 High Mass Impact Test, Test 9.6 Drop Ball Test, and Test 9.11 High Mass Impact Test. ANSI Z87.1 is a requirement for many occupations and sometimes preferred for certain activities such as motorcycling.
