Always pushing boundaries, Transitions Optical challenged its research team to develop a light intelligent photochromic lens that was darker outdoors, clear indoors, with improved reaction and fade back speeds, all without compromising on protection and quality.
The result of years of research and in-depth scientific studies, Transitions Signature GEN 8 is the first light intelligent photochromic lens with a revolutionary nano-composite technology that pushes photochromic performance. It also offers optimum vision, comfort and protection all day long.
Transitions Signature GEN 8 is suited to people that:
Please note: Not all lens colours are available in each material or design
Clear indoors, Transitions XTRActive new generation quickly becomes extra dark outdoors. It is the only photochromic lens to achieve category 3 lens darkness at 35°C and category 2 lens darkness in the car.
XTRA DARKNESS WITH XTRA LIGHT PROTECTION*
The only photochromic lens to achieve category 3 lens darkness at 35°C*
The only photochromic lens to achieve category 2 lens darkness in the car
Compared with previous Transitions XTRActive generation
Transitions XTRActive new generation filters up to 45% of blue-violet light indoors and up to 86% of blue-violet light outdoors³
Helps reduce glare from harsh artificial lighting, digital devices and screens
Everyday eyecare blocking UV outdoors
Transitions XTRActive new generation lenses have been tested by wearers in their daily life with impressive results and an overall satisfaction rating of 98%⁹.
The protection offered by Transitions XTRActive new generation lenses – especially in bright sunlight outdoors – is often the first thing wearers appreciate about the lenses.
Transitions XTRActive is suited to people that:

* Darkness compared to previous Transitions XTRActive generation. Light protection from glare and UV, plus increased blue-violet filter.
¹ Clear to extra dark photochromic category. Tests across polycarbonate and 1.5 grey lenses using Transitions Optical’s standard testing method. Outdoors at 35°C achieves <18%T. Behind the windscreen at 23°C achieves between 18%T and 43%T.
² Compared to the previous Transitions XTRActive generation across materials tested on grey lenses fading back to 70% transmission at 23°C.
³ Tests performed on grey CR39 & polycarbonate lenses with a premium anti reflective coating. Blue-violet light is between 400 and 455nm (ISO TR 20772:2018)
⁹ Transitions Optical, Quality of Vision and Vision Experience Test In Real Life situations (Life Wearer Testing), France, Eurosyn, Q3 2020, N=148 – Top4Boxes *Based on wearers who preferred XTRActive II lenses (32% of total wearers). Caution: small base size (n=46 wearers who preferred XTRActive II lenses).
Transitions XTRActive Polarized is extra dark outdoors, even in hot temperatures. The darker it gets, the more it becomes polarized to reduce glare outdoors and provide a better vision experience. Transitions XTRActive Polarized darkens in the car.
THE ONLY DYNAMIC POLARIZED PHOTOCHROMIC LENS.
Achieves up to category 3 sunglass darkness
Darkens in the car for light protection on the road
For sharper vision, a larger field of view and vivid colours outdoors
Filters up to 45% of blue-violet light indoors and up to 90% of blue-violet light outdoors⁷

Transitions XTRActive Polarized is suited to people that:
⁴ Based on tests on polycarbonate grey lenses; up to 10% darker than Transitions Vantage @ 23°C and up to 5% darker @ 35°C.
⁵ Based on tests across materials on grey lenses, achieving transmission below 45% @ 23°C behind a standard windscreen. The lens achieves a polarisation efficiency of up to 30% behind the windscreen.
⁶ Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard.
⁷ Filters up to 45% of blue-violet light indoors. Tests performed on grey Transitions XTRActive Polarized and clear lenses, CR 39 and polycarbonate, with a premium anti reflective coating. Blue-violet light is between 400 and 455 nm (ISO TR 20772 2018).
⁸ Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard tests across materials on grey lenses @ 23°C.
