Transmission: approx. 91% Yellow Offers good vision and contrast under poor lighting conditions. Protection against mechanical hazards. Transmission: approx. 88% AR – anti-reflective For optimum vision when working with light-coloured reflective components without tiring the eyes. Protection against mechanical hazards. Transmission: approx. 96.5%. I/O – Indoor / outdoor Ideal for use under fluctuating lighting conditions (indoors and outdoors). Reflects sunlight without attenuating it excessively. Protection against mechanical hazards. Transmission: approx. 55% CBR – Contrast, Blue light reduction, Relax The tinting has the effect of increasing the contrast, reducing the blue light and promotes relaxed vision. Protection against mechanical hazards. Transmission: approx. 65% Grey Suitable for working outdoors, where harsh sunlight quickly tires the eyes. Satisfies the requirements of road traffic safety. Protection against mechanical hazards. Transmission: approx. 22% Blue reflective Ideal for use when working outdoors. Eliminates dazzle cause by reflection of light from surfaces. Protection against mechanical hazards. Transmission: approx. 13%. Polarisation Additional protection symbols For activities where there are distracting reflections of light from surfaces. Protection against horizontal glare and mechanical hazards. 8 Protection against electric arcs Transmission: approx. 14% 9 Protection against molten metal and hot solid bodies IR K Scratch resistance Suitable for welding work. Protection against UV and IR radiation, N Anti-fogging protection and also against mechanical hazards. R P rotection against amplified radiation Protection levels: due to IR 1.7 or W 1.7 = welding assistant 3 or W3 = soldering, cutting 5 or W5 = gas welding, soldering, transmission according to protection level: approx. 54%, 15%, 2% 29
