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 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.
