Photochromic" lenses are lenses that automatically change from clear to dark in the presence of ultraviolet (UV) radiation. They adjust automatically to changing light conditions-going from clear indoors to as dark as sunglasses in bright, glaring
sunlight.
Transitions Optical, Inc. has developed the world's most advanced photochromic lens technology. Transitions? lenses are the #1 brand of photochromic lenses recommended by eyecare professionals worldwide.Transitions lenses change from clear indoors to sunglass-dark outdoors in proportion to the intensity of UV light. This enables them to enhance visual quality and comfort, plus provide convenient protection from the harmful effects of UV
radiation and glare.
Today's photochromic lenses with anti-reflective (A/R) coating reduce more kinds of glare than any other type of lens and can be worn both indoors and outdoors, day and night, making them the ideal lenses for everyday wear.While Transitions lenses meet the everyday needs of the majority of people, the truth is one pair of glasses can't do it all. For example, while driving, the windshield of a car blocks the majority of the UV radiation that causes photochromic lenses to darken. In this case, many wearers find it can be helpful to have a second pair of prescription polarized
sunglasses or prescription sunglasses.
These wearers can still benefit from Transitions? Photochromic Technology, with special-purpose lenses that carry the
Activated by Transitions? name.
Like Transitions lenses, lenses that are designated as Activated by Transitions provide 100 percent UV blockage. All products that carry the Activated by Transitions mark have been enhanced with superior and patented Transitions Photochromic Technology to automatically optimize visual performance in variable light conditions and to help protect eye health and well-being for the future
