The Wiley X Romer II Advanced is tailor made for U.S. military and law enforcement personnel, providing a high level of ballistic protection for the performance requirements of the most demanding mission-critical situations, all in a stylish and comfortable package. The Wiley X Romer II Advanced provides not just an impact and heat-resistant frame, but also three easily interchangeable lenses for the unmatched versatility. The design of the Wiley X Romer II Advanced makes it easy for those in law enforcement or the armed services to switch between precision Clear, Smoke or Light Rust lenses, finding the optimal choice for the given situation or shooting environment. These 8-base curvature lenses are manufactured from shatterproof 2.0mm Selenite polycarbonate, and treated with Wiley X’s T-Shell and Foil coatings for maximum scratch resistance and anti-fogging protection. The Wiley X Romer II Advanced is certified to ANSI Z87.1-2003 High Velocity Impact, VO Ballistic Impact Test MIL-PRF-31013, which requires that eyewear withstand the impact of a .15 caliber steel fragment fired at 640-660 feet per second, and CE EN 166 (F) Standards. Engineered to protect and enhance vision in potential life-and-death situations, these glasses naturally provide wearers with 100 percent UVA/UVB protection and distortion free vision under the most challenging conditions.
