Engineered in partnership with Wiley X, a global leader in sports and military eyewear, the 5.11 Tactical Aileron Shield Ballistic Glasses combine adaptability, durability, strength, and style in one high-performance package. Aileron Eyewear includes three sets of polycarbonate high-impact-rated lenses (providing 100% UVA/UVB protection) that can be quickly mounted or removed from a high-strength nylon frame, enabling you to adjust your light-reduction preferences to match your surroundings. The lenses are fully prescription-ready, and arrive in three distinct tints to suit a wide range of environments: Clear, Smoke, and Ballistic Orange. Aileron Shield Ballistic Glasses meet ANSI Z87.1 2010 and EN166 (+F) High-Velocity Impact and Optical Safety Standards and exceed MIL-GL-PD-10-12 U.S. Military Combat Eye Protection Systems Standards for Impact and Optics.
