PHOTOCHROMIC MOLECULES CONTINUOUSLY ADJUST TO LIGHT

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.

Only Transitions lenses use exclusive technology, from patented formulas that are the result of more than 20 years of research and innovation. 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.


FROM ORDINARY LENSES TO EXTRAORDINARY TECHNOLOGY

Transitions Optical’s photochromic technology becomes an integral part of the lens through one of two proprietary processes.

One process is called imbibing. Derived from the Latin word imbibere meaning, to drink in, this method uses heat to draw the photochromic dye into the lens itself. After the imbibing is complete, a scratch-resistant coating is applied to the surface of the lens.

A number of lens materials do not imbibe readily. In these cases, another method called Trans-Bonding™is used. Where imbibing places the photochromic technology below the lens surface, the patented Trans-Bonding puts the photochromic technology on the lens surface.

Unlike the method used by some other type of photochromic lenses, both imbibing and Trans-Bonding methods provide the same uniform tint colour across the surface of the lens, regardless of lens thickness differences caused by lens prescriptions. At Transitions Optical we develop and adapt our processes for optimum photochromic performance, lens durability and compatibility with other lens treatments such as anti-reflective coating.

Transitions Optical is the only optical company that has its proprietary photochromic technology. That’s why we are a trusted worldwide leader: one Transitions lens is sold every second around the world.


BEHIND THE WINDSHIELD

Most photochromic lenses react primarily to UV light. That’s why they change when you’re in the sun yet remain clear indoors.

In the car, the glass in car windshields blocks most UV light. That’s why most photochromic lenses do not provide sufficient darkening in the car. But the special photochromic molecules in Transitions XTRActive lenses responds to both UV light and natural (visible, clear or white) light, so they are able to darken in the car – something no clear lens can do!.

We also recommend a pair of prescription sunglasses. Transitions® Drivewear® adaptive lenses enhance the driving experience by combining two of the most advanced technologies in the eyeglass industry. NuPolar® Polarization eliminates glare off the road and car hood. Transitions photochromic technology adjusts the color and tint of the lenses as light conditions change.
