photochromic lens technology

Select styles of the Lazer eyewear range offer photochromic lenses that change color automatically based on varying light conditions. As the sunlight becomes more intense the lenses change from a light color to a dark color. Total lens change occurs in 7 seconds. Alternatively the lenses return to a more translucent state within 1.5 min. from being removed from sunlight.
