Bosch Sensortec has developed a system called “Light Drive” that can turn all kinds of glasses into smart glasses. Corrective glasses and contact lenses fitted with “Light Drive” can insert information that remains invisible on the outside. This includes navigation routes, chat messages, memos and appointment reminders. “Light Drive” is linked to a software program and integrates microelectromechanical mirrors, optical elements and sensors. It doesn't use a visual external display or a camera, and generates a high-resolution image on the surface of the retina, even in direct sunlight.
