With their curved polycarbonate lenses, these Arco Halo KNT safety glasses provide excellent wraparound eye protection without the visual distraction of side shields, while the lenses also feature special anti-fog and anti-scratch coatings. They're fully adjustable too to ensure a great fit to the wearer's face. Meanwhile, the soft browguard across the top of these safety specs helps to shield the eyes from any dirt ingress.
