Polarised lenses
Polarised lenses are optical elements that block the light radiation depending on its polarisation. They eliminate distracting
reflections. Made from super-tough polycarbonate complying with requirements of EN166 and EN172. Reinforce colour
saturation and visual contrast.
Reduce eye strain, protect against harmful UV radiation.
