The Astrospec 3000 safety glasses from Uvex have a single-piece, scratch-resistant polycarbonate lens. The frame adjusts to three positions for optimal fit and comfort. The 135mm lens features molded-in side shields and brow guard for extra protection. The lenses block over 99% UVB and 99% UVA radiation up to 385nm. The 4C+ coating minimizes fogging, scratching, static and provides additional UV protection. The Astrospec 3001 safety glasses are the same as the Astrospec 3000 described above only designed to fit over prescription eyewear.
