Younger Optics has done it. It's a new product called DriveWear and it's available in S.V. only for the time being. It features NuPolar technology and Transitions lenses that work while inside the car. Here is what Younger says about this product. "Drivewear is the only lens developed to specifically address the Driving Task. Polarized at all times and designed to shift between a lighter and darker color as visual conditions change, it is the ultimate driving eyewear." You can learn more about this product at Vision Expo, or wait until it is released next month.
