K3s PhotoChromic

The Special TAC 1.2 mm photochromic lens designed for our Siroko K3s is sensitive to distinct changes of light by adapting to each moment in an extremely efficient way. Ideal for cloudy and clear days, and also for environments in which sunny and shadowy areas alternate.

The K3s PhotoChromic lens controls the transmission of light independently, going from category 2 to category 3 in less than sixty seconds, optimizing contrast and favoring visibility (The percentages may vary slightly). The lens does also count on our DrySky ventilation system and anti-fog coating to guarantee excellent vision and avoid condensation.
