The Smoke Black: 22 percent Light Transmission are truly dark and perfect for summer or really bright days. And like the other Rydon spare lenses, they are easy to change out if the light or weather changes.

The transparent (92 percent Light Transmission) spare lenses are a must-have for riding in the fall and winter months when there isn't as much sun.
They're also great on mixed weather days when the sun is out, but the chance of rain is high. The lenses are small enough to carry with you in the included cloth holder and can be swapped out should the need arise. What's more, objects appear super clear through these lenses.

Just bought a set of ImpactX-2 Photochromic Clear to Black lenses for my Rydons. Great lens for early morning rides. Starts clear and darkens nicely as the sun comes out. This lens complements the brown, racing red and clear lenses, and I now have all conditions covered.
