Clear lenses provide high mechanical protection as well as high UV protection by filtering the harmful UV rays. The lenses provide unimpaired colour perception and comply with EN 170.

Amber lenses comply as UV filters with EN 170 and offer high mechanical protection. The spectral characteristics of the filter show absorption of the blue light in the visible range, providing contrast enhancement.

Brown lenses type SCT 400 (Spectrum Control Technology) are sunglare filters according to EN 172, providing UV and glare protection. The lenses show strong linear absorption in the blue range of the visible light and additional partial absorption in the infrared, providing enhanced protection. The lenses offer high mechanical protection.

Grey lenses comply with EN 172 and are sunglare filters. They filter harmful UV rays as well as visible light, offering UV and glare protection. They provide good recognition of signal lights as well as high mechanical protection.

Green lenses as UV filters according to EN 170 filter harmful UV rays as well as visible light, providing UV protection and glare protection. They provide high mechanical protection.

Green infradur PLUS lenses comply with EN 169 welding filters and absorb the rays caused by gas welding processes: UV rays, IR rays as well as glare. They provide higher levels of mechanical protection than glass filters.
