1. Traditionally, riders deal with changing light conditions by carrying two shields (one clear, one tinted) with them at all times. Photochromic adaptive shields not only eliminate the need to carry multiple shields, they actually enhance vision by seamlessly adjusting to optimized darkness levels with the changing light.

2. Photochromic shields work the way they do because the molecules that are responsible for the darkening of the shields are activated by the ultraviolet radiation in sunlight. UV rays can penetrate clouds, which is why photochromic shields are capable of darkening on cloudy days. Direct sunlight is not required for them to work.

3. How quickly do they change?

Well, photochromic shields are known to darken more quickly than they lighten and the speed it takes is slightly temperature dependent too. But, if it’s a really bright and sunny day, they’ll typically reach max darkness in about 20s – or about the time it takes to get on your bike, put your helmet on and set off.

4. Photochromic performance is influenced by temperature, UV exposure and riding posture.
