These exact sunglasses were the first to go to the moon with the crew aboard the Apollo 11, and have long been spec for U.S. Air Force pilots. Designed specifically to fit under a helmet or headset, and engineered to rigid military specifications, they offer maximum protection, optical performance and comfort. The neutral grey, scratch- and shatter-resistant glass lenses absorb 99% of UVA and UVB rays, and allow for sharper detail and evenness of color. The rugged, high-quality frames are made of polished steel and the earpieces are designed for maximum comfort no matter how long they’re worn. These timeless masterpieces have been issued to millions of soldiers, sailors, marines and airmen since 1958, and have never gone out of style.
