Transitions® Lenses
Perfect everyday lenses: ultra-responsive to light, spectacular colour palette, HD vision at the speed of your life.
Photochromic lens molecules make light, dark and every shade in between possible.
How do Transitions® lenses work?
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® technology lies in 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.
An Extraordinary Technology
The Transitions® photochromic technology becomes an integral part of the lens through one of two specialised processes.
- Imbibing: 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.
- Trans-Bonding™: A number of lens materials do not imbibe readily. In these cases 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.
Both methods provide the same uniform tint color, regardless of lens thickness differences caused by lens prescriptions.
