The Pyramex safety goggles are certified to stringent military standards (MIL-PRF-32432 or ANZI.Z87.1+) and offer optimal ballistic protection. They also effectively protect your eyes against 99% of UV A/B/C rays. This is achieved through the use of two lens layers. The outer layer is coated with an H2X anti-fog coating, which reduces the risk of fogging. Furthermore, both layers are highly scratch-resistant and easy to clean. The goggles can also be completely disassembled for cleaning; the foam-padded frame can be separated from the temples and the safety strap.
