lenses contain photochromic molecules that react to UV rays. The brighter the light, the lens the lens . In full shade, they return to their clear state. The transition is gradual and automatic—you don’t have to do a thing.

From light to dark: about 20 to 30 seconds in direct sunlight. From dark to light: about 60 to 90 seconds in the shade. Fast enough to handle sudden changes in conditions during intense activity.

Partially. Modern windshields block some UV rays, which slows down the photochromic reaction. For driving, standard lenses are better suited. For outdoor sports, EVO+™ lenses are ideal.
