Our photochromic lens 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.

Improve your performance
Get your sport sunglasses ready for any sporting event thanks to our interchangeable lenses which are sold separately. Designed with specific top-notch tech specs to offer you the definition and contrast you need for any occasion. The hardshell case included with your sport sunglasses offers you the needed space for the storage of additional lenses.
Forget about the sun, clouds or annoying reflections that may interrupt your activity. The photohromic lenses adapt to the continuous changes of light luminescence and become the best option for sports such as MTB, Triathlon or Running.
Thanks to its production with photochromic materials instead of being made out of one simply-added layer; the interchangeable K3s PhotoChromic lenses change from one category to another in only a few seconds (these categories may vary slightly depending on the type of photochromic lens you have chosen). They also count on an additional polarized layer and full UV400 protection, which provides you with a bigger degree of protection against glares and reflexes.
For low light conditions where you still need some extra protection against wind gusts and little impacts: K3s Clear.
And if you need high contrast to fight foggy weather: K3s ClearFog.
