Photochromatic technology
Photochromic lenses automatically adjust to light intensity. 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.
Product Reviews


Brought these because of them being photochromic property and they haven't disappointed. I don't notice them change, but they do. None of my rides have sudden changers of light that these glasses can't cope with. They fit nicely, prevent wind in the eyes and don't bag on my helmet for the price excellent buy.
Excellent pair of cycling glasses. Fits perfect and look good too. Very well priced too.
Fantastic glasses. I use them for both MTB and road cycling. Darken as expected.
