The increased use of digital devices has brought blue light to the forefront of people’s minds, but harmful blue light is actually present both indoors and especially outdoors. What most people don’t know is that the sun is the largest singular source of blue light, scattering it through the atmosphere and emitting over 100 times the intensity of electronic devices and screens.


Transitions® lenses help protect against harmful blue light everywhere you need it — both indoors and outdoors. Indoors, Transitions lenses help protect eyes against harmful blue light emitted by arti cial sources. Outdoors, they help provide extra protection from the sun by shielding eyes from glare, intense harmful blue light and UV rays. Transitions® XTRActive® lenses are most effective — they help protect against harmful blue light everywhere you need it by blocking at least 34%* of the harmful blue light indoors and 88% to 95% of harmful blue light outdoors. Anywhere they go, Transitions XTRActive lenses are always working to help protect patients’ eyes from the brightest sun and harsh artificial light. They provide extra protection from light outdoors, indoors and even in the car.

  • Outdoors: Uniquely designed for extra light protection, even in the brightest sun and hottest conditions.
  • Indoors: A hint of tint helps protect eyes from harsh indoor lighting, helping to reduce eye strain and fatigue.
  • In the car: Achieves up to category 2 darkness behind the windshield to protect eyes from sunlight while driving.

Most photochromic lenses react primarily to UV light. That’s why they change when you’re in the sun and remain clear indoors. Transitions XTRActive lenses feature a broad spectrum dye specially designed to react to both UV and visible light for extra darkness outdoors and in the car, which helps protect your eyes from fatigue and strain caused by UV light and bright glare.

These lenses are best for patients who spend more time outdoors and in the car, are light sensitive or especially concerned about eye health and are interested in products with increased functionality.
