DriveWear® lenses are the first and only photochromic lenses to darken behind the windshield of a vehicle, with the ability to react to visible light as well as UV light.

In the past, clear eyewear was enough. In bright light conditions, polarized sunwear was enough. This is no longer true. Today our lives are strongly influenced by the automobile, which has changed the way we experience the outdoors. We need a third category of lenses in our modern, automobile-centered world. Drivewear®. Drivewear® lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car. From bright sunlight accompanied by intense, blinding glare, to overcast inclement conditions, Drivewear® lenses provide the wearer with the appropriate visual solution. Drivewear® lenses provide glare protection through polarization and enhance and protect vision through photochromics which respond to both visible and UV light. By combining the strengths of two of the most important technologies in eyewear today we have developed the lens of tomorrow, Drivewear®.

By combining polarization with new photochromic technology, DriveWear lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car. From bright sunlight accompanied by intense, blinding glare, to overcast inclement conditions, DriveWear® lenses provide the wearer with the appropriate visual solution.

 

At low lighting conditions, Drivewear® lenses provide high transmission of light to maximize the total information to all the eye’s visual receptors. This results in maximum visual acuity at this low lighting level. The high contrast polarizer removes glare that would otherwise destroy vision in low light conditions. In this stage Drivewear® lenses are a high contrast green/yellow color. Simply, there is no better designed lens for either outdoors or while driving under low light, overcast conditions.

 

During bright light conditions behind the windshield of a car, Drivewear® lenses provides lower overall transmission to control light intensity for optimum visual acuity. Drivewear® lenses promote preferential activation of the eye’s red cones (and to a lesser extent, green cones) and result in the best possible vision at these higher light levels. Drivewear’s high contrast polarizer is absolutely essential behind the windshield of the car, because it blocks out blinding glare, one of the most dangerous of all driving hazards. Under these conditions, the Drivewear® lenses turn a copper color which many feel is the optimum color for a driving lens. This unique behind-the-windshield response protects against bright light and glare and provides better sensitivity to the “visual signal” that is vital for safe driving.
