Admittedly the technology isn’t quite new: Uvex introduced Variotronic-technology to ski-goggles last year. Now however the Fürth based company is bringing the tech to bike glasses in a new, sleek framed model. The Variotronic-glasses are equipped with a laminate of liquid crystals which can electro-chromatically adapt to light conditions either automatically by means of a light sensor or manually by pressing a button. The required battery is integrated in the frame and has a run time of 50 hrs in the tinted mode. It is charged via a USB-port. The new glasses are available either in a Sports Shield or a full framed version in two colours (orange/white or black) for € 299.95.
