It’s hard not to jump to sci-fi imagery of bionic eyes that let someone scan objects and see several miles away—but the reality of bionic glasses is actually much cooler than all that. According to scientists at Oxford University, bionic glasses will help the visually impaired “see” better. Using technology normally found in smart phones and video game accessories, these high-tech specs make use of cameras, face tracking software and sensors. Video cameras mounted to the frames will capture everything in front of the person wearing them, while the lenses display tiny lights. Different colors could represent different things, such as people or objects, while brightness could convey proximity. The glasses could also provide audio feedback played through an earpiece. Expect the glasses to cost around $800, which is significantly cheaper than training a seeing eye dog.
