Lenses that change automatically to lighting conditions.
How do Transition® Lenses work?
When photochromic molecules of a Transitions® Lens are in their resting state they allow all visible light to come through the lens. Even in the resting state lenses block 100% UV A and UV B light. When the photochromic molecule becomes exposed to an energy source (bright sunlight), a complex molecular reaction occurs and changes chemical bonding and, thus, the shape of the molecules in the lens. In the fully activated state, the photochromic molecules are folded into completely new configurations. These configurations absorb light more effectively than the resting state and make the lens look dark. When the energy source is removed the molecules will always return to their original position and the lens lightens to its original color.
Spend a significant amount of time driving?
Drivewear® lenses have the ability to sense various light conditions and automatically adjust for those conditions, even from behind the windshield of a car. Photochromatic properties of this lens respond to both visible and UV light to protect your eyes from the sun and reduce glare.
