Have employees who need larger safety glasses to fit over their prescription lenses? This is the choice for you. The UVEX Astro OTG glass boasts a 145mm wide, single-piece, polycarbonate lens that adjusts to three positions and slips over most prescription glasses with ease. Molded-in sideshields and browguard add extra protection above and around eyes. Temples adjust to four different lengths and feature the UVEX-patented Duoflex feature for improved comfort behind the ears. Replacement lenses are available through your service representative.
