HellFire Transitional Light to Dark UV Lenses

 

 

The science behind what makes a photochromic lens transition from light to dark is quite simple. There is a chemical reaction that occurs when a photochromic lens comes into direct or inadvertent contact with UV rays. The stronger the UV rays are, the darker the lens will transition. If there is limited exposure to the sun's rays, then the lens will not fully transition. Instances when this will occur will be inside a vehicle or behind a full face helmet that has a UV filtering laminate. The temperature and elevation can affect the way that the photochromic lens changes as well.
