Certification: EN 166, EN170, EAC, ANSI CSA Z94.3. Bolle's technical safety glasses for work provide a very comprehensive level of protection against mechanical and chemical risks. Clear Platinum-coated lenses are suitable for indoor use. The glasses can be worn as a headband or with the included headband. Removable foam frame. When worn as a headband, they protect the eyes from UV rays without interfering with color vision, and from low-energy mechanical hazards (6 mm 0.86 g metal ball 45 m/s), even in extreme temperatures. Additionally, when equipped with a headband and foam frame attached, they protect against chemical droplets, coarse dust (>4 microns) and medium-energy mechanical hazards (6 mm 0.86 g metal ball 120 m/s). Anti-fog and anti-scratch coated lenses that significantly exceed the requirements of Class N and Class K test methods. Optical Class 1 for polycarbonate lenses: Designed for long-term continuous use.
