ESS Crossbow (RX Capable) The ESS Crossbow protective spectacle consists of a plastic frame (one size) with interchangeable polycarbonate lenses. The frame and lens assembly weighs 1.2 ounces. All lenses have been treated with a hard-coat on the exterior surface to reduce scratching and an anti-fog coating on the interior surface to reduce fogging. The ESS Crossbow provides ballistic-fragmentation protection, and meets all ANSI optical and safety requirements. The lens material blocks 99.9% of all UVA and UVB light. An optional prescription lens carrier is available for those who require corrective lenses. More informatoin at
