A "Certification Statement of Impact Resistance" is a written statement from the manufacturer guaranteeing that the lenses have been tested and are impact resistant. FDA may accept such a certification in lieu of test results, but a manufacturer must
make the results available, upon request, to the FDA as soon as practicable.
The regulation states,"In the impact test, a 5/8-inch steel ball weighing approximately 0.56 ounce is dropped from a height of 50 inches upon the horizontal upper surface of the lens. The ball shall strike within a 5/8 inch diameter circle located at
the geometric center of the lens. The ball may be guided but not restricted in its fall by being dropped through a tube extending to within approximately 4 inches of the lens. To pass the test, the lens must not fracture…."
To pass the “Drop Ball" or impact test, the lens must not fracture.
You may “drop ball” test laminated eyeglasses or sunglasses individually or on the same statistical basis as plastic lenses, unless they are of a type unsuitable for impact testing.
FDA has strict restrictions to ensure the effectiveness of the "falling ball" test and impact test.
