ESS 5B Prescription Sunglasses give you style, durability, and full ballistic protection, on duty and off - and all that is combined with single-vision prescription lenses that let you see with unparallel clarity. Designed by an ESS-authorized optics lab, the lenses of your ESS 5B Rx Sunglasses meet the full ballistic and impact protection standards set by the original ESS 5B. ESS has designed these military sunglasses based on years of customer feedback. A full-wrap design and thick temples mean that that these ESS Sunglasses provide an extra measure of protection on all sides, while the flat, wide temple arms make them highly helmet - and comms compatible. With a comfortable universal-size fit, the ESS 5B Rx Sunglasses are everything a soldier or officer could want in prescription eyewear.
