THE DRIVEWEAR ENGINE |
Drivewear lenses feature a high efficiency polarizer never before found in such a high contrast, light color. This color was chosen and designed to maximize useful light reaching the eye in low light/ overcast conditions. This polarized film is active in every lighting condition to block blinding glare and improve visual acuity. |
 One of the most unique and special attributes of Drivewear is that it is the only photochromic lens to darken behind the windshield of a car. Exposed to visible light, the lens changes to a copper color, which many drivers find is the most comfortable color for driving. This is not surprising, as this Drivewear color was designed to both remove excess light and provide good traffic signal recognition. |
 Outdoors, Drivewear is activated by UV and visible light and deepens to a dark reddish-brown color. This color was designed for maximum filtration of excess light and to provide maximum protection from bright light and blinding glare. The brown color of the lens provides excellent color recognition with a special emphasis on highlighting greens. Because green is the most common color in the natural landscape, it’s a great visual experience to have these enhanced.

UNIQUE TRANSITIONS™ PHOTOCHROMIC TECHNOLOGY
Dynamic reaction to light, plus 100% blocking of UV A & B
In low lighting conditions, such as an overcast day, the photochromic molecules of a Transitions® Lens are in an uninitialized or “resting” state. In this state, the molecule allows all visible light to come through the lens. However, even in the resting state, Drivewear lenses block 100% UV A and UV B light. This is one advantage of being Activated by Transitions™.
When the photochromic molecule becomes exposed to an energy source (bright sunlight), a complex reaction occurs and changes chemical bonding and the shape of the molecule. What is unique about Drivewear is that this activation is initiated not only by ultra violet (UV) light, but also by visible light.
In the fully activated state, the photochromic molecules are folded into new configurations. These configurations absorb light more effectively than the resting state, and therefore, the lens looks dark. When the energy source is removed, the molecule will return to its original position and the lens lightens in color. With Transitions® Photochromic Technology, this process can repeat over and over for the lifetime of the lens. |

Caution: Drivewear lenses are optimized for sunlight response. They should not be used for night driving. Caution: Like all photochromic lenses, Drivewear lenses are somewhat temperature dependent. At cooler temperatures (below about 10°C or 50°F), these lenses may become very dark on sunny days and may be too dark for driving open air vehicles such as motorcycles, conver tibles or all terrain vehicles. At these colder temperatures par ticular care should be used when going from sunny to shady areas when, for example, skiing, snowboarding or driving snowmobiles.
