Transitions® Premium™


Variable-tint lenses, a perfect balance

The technology Transitions® Premium™ is the leader of photochromic lenses. The Transitions Premium technology combines the benefits of prescription glasses and high performance sunglasses, all while blocking 100% of harmful UVA- and UVB-rays.

The lenses continuously adapt to changing light conditions, from 6% in the shade to 86% when exposed to full sunlight. The lenses also darken under indirect light and higher temperatures. This is possible thanks to the new Cromea7™ technology.


The new Transitions® Premium™ lenses are more reactive to direct and indirect sunlight. They darken under the sun, under all circumstances : with your back to the sun, when the light reflects, regardless what place you are at or what moment of the day it is. Back indoors, they brighten fast. Wherever you are, your visual performance will be perfect.

  • Perfectly clear at night, and indoors
  • Brighten fast
  • 100 % protection of harmful UVA and UVB-rays
  • Compatible with all prescriptions and styles of frames

Perfect for those who want variable-tint lenses, for active people who continuously go out and come back home at different times of the day (shopping, lunch...) and for people who do outdoors activity while spending a lot of time indoors.

Ordinary lenses, extraordinary technology

When Transitions® lenses are exposed to UV-rays, the structure of trillions of photochromic molecules, present in the lens, start to adapt. This reaction sets off the darkening process of the lenses.

This exclusive technology is the fruit of 20 years of research and innovation, and this patented formula is exclusively used by Transitions®. The technology is integrated in the coating of the lens. The molecules reorganise permanently without you even noticing. Your eyes receive the right amount of light under all circumstances, whether you are under an open or under a clouded sky, or inside.

Thanks to two exclusive methods, we are able to integrate the photochromic technology Cromea7™ in the lenses. Contrarily to other types of photochromic lenses, this technique allows to obtain an even tint on the entire surface of the lens, regardless of the thickness of the lens. Transitions Optical develops and adapts his techniques to optimize the photochromic performances, the durability of the lenses, as well to enhance the compatibility with other coatings, like for example the anti-reflective coating.
