Category 1 to 3 photochromic lenses: filter varying from 15% to 55% of the light at 23°C. In cold weather (under 10C°) the variation in the tint is greatly diminished. Standard: ISO 12312-1. Full UV protection filter Material: impact-resistant polycarbonate. Full coverage for optimum protection from the elements (mud, dust, insects, etc.).

Photochromatic lenses adjust automatically to ambient light levels. Lenses darken in approximately 30 seconds (takes 45 seconds to lighten). The perceived brightness does not change much even when the outside brightness level changes. For example, when cycling, the change in tint is almost imperceptible. The tint adjusts gradually, and the eye adjusts to it. The lenses tint faster in cold temperatures.
