Here is an advanced wearable device that allows the legally blind to actually see. eSight 3 uses a high-definition camera to capture everything users are looking at and display images on two OLED screens in front of their eyes. This hands-free device has almost zero latency. It allows users to make adjustments and auto-focus between short to medium to large range vision.
eSight simply allows legally blind people to get things done in a more independent fashion. What do you think? Are you impressed?
