3 Product Description 3 The EPS-21 (Eye Protective System for the 21st Century) is an advanced sun, wind, and dust goggle for the military user. The goggle has been successfully tested in accordance with ANSI Z The modular concept consists of a basic goggle, made of advanced materials, with a 4mm thick ballistic lens, which has a scratch resistant, anti-fog coating. Outsert lenses provide sunshade protection. Reduced eye-to-lens clearance yields improved interface with optical sighting equipment. The goggle retention strap, available in a standard version or a ski version, may be configured for use with or without helmets. A soft case holds all components on the belt or other user-selected attachment location. The goggle accepts a prescription snap-in frame for users who require corrective eyewear.

The carrier is held in place by the two plugs which catch on a bracket inside the goggle. To remove, grasp one end of the carrier and pulling it away from the bracket until it pops out.
