Meet the eSight: a pair of electronic glasses that enable legally-blind folks to see. It combines a camera, display technology, and advanced computing to deliver a real-time video, allowing people with vision loss to see. Users can magnify and adjust the image for their eyes. The system consists of a headset with high-definition camera, OLED screens, and technologies to capture and display a real-time video feed. The processing unit which does most of the hard work is portable and light.
The above videos show how these glasses work. You can find out more information here.
