Photochromic lenses are lenses that are clear indoors and darken automatically to a sunglass tint when exposed to sunlight.  The term photochromic refers to this feature of changing color ("chroma") in response to light ("photo-"). 

Though photochromic is the proper generic term for all lenses that darken in sunlight, these lenses are often referred to by a specific brand name, such as Transitions(R) (made by Transitions Optical) or Sunsensors(R) (made by Corning).  Other terms used to describe photochromic lenses include variable tint lenses and lenses with sun-activated tints.

All photochromic lenses block 100 percent of the sun's harmful ultraviolet (UV) rays

Corning has recently introduced a lightweight, high index plastic photochromic lens called SunSensors(R).  This lens also has photochromic material uniformly distributed into the front surface of the lens, but has a penetration depth that is significantly thicker than the photochromic layer in Transitions lenses.  This extra-thick photochromatic layer enables SunSensors lenses to change faster and get darker than other photochromic lenses, according to the company.

We supply Grey SunSensor lenses with a hard coating to the Davida Goggle.

Please note that if using a full face helmet with a polycarbonate visor the photochromic lens won’t work as the visor bocks out UV light.
