Photochromic solutions that fit your lifestyle and visual needs:
When Transitions® lenses are exposed to UV light, trillions of photochromic molecules in the lens begin to change structure. This reaction is what causes the lenses to darken.
All lenses that adapt to light use photochromic molecules; the superiority of Transitions brand technology lies in our exclusive, patented formulas. Each formula is integrated into the surface of the lens. These molecules constantly and smoothly recalibrate so the optimal amount of light reaches your eyes whether you’re in bright sunlight, under cloud cover or indoors.
This exclusive, patented formulation consists of unique dyes that are integrated into the surface of the lens. The dyes are made up of molecules that constantly and smoothly recalibrate as the light around you changes. They darken and lighten to just the right degree so the optimal amount of light reaches your eyes.
More reactive to indirect light
Chromea7 technology was designed to be even more reactive to indirect light. Indirect light can come from many sources such as light bouncing off buildings, cars, or other surfaces or light filtering through trees or clouds. The lenses can sense this light, even when you’re facing away from it, and adjust to the appropriate shade for your situation.
More responsive in hotter climates
Temperature influences the molecules in photochromic lenses; they don’t get as dark in hot climates as they would in colder weather because of how heat interacts with the molecules. The molecules in Chromea7 technology were structured to be more independent of temperature, which means they get darker in hotter climates.
Just the right shade, just the right colour
In other photochromic lenses, wearers have noticed color variations as the lenses tint and react to different types of light. The dyes in Transitions® lenses and in Chromea7 technology work together to provide an even colour at all levels of tint, in both grey and brown options.
Revolutionary testing for a revolutionary product
People wear their lenses all day, every day, in a variety of locations, temperatures and weather conditions. They experience sunny conditions, cloudy conditions and everything in between. Their position in relation to the sun also changes quite a bit. We took all of these factors into account when we tested Chromea7 technology in over 200 real life conditions representing over 1,000 scenarios that wearers experience around the world. We call it Life360™.
