protects against short circuit electric arcs with its RELPSI version featuring a 1 mm polycarbonate anti-fog lens. Chemical protection against liquid droplets or splashes. The anti-fog coating allows you to work in optimal conditions by removing the effect of condensation that occurs when there are large temperature differences or when wearing non-ventilated frames. The anti-scratch coating acts as a shield that improves the resistance of lenses and reduces the formation of scratches.
