We take for granted that our senses are there to help us navigate the world. If you're lucky, your hearing works well; you can taste when food goes bad or smell when the garbage has to go out, and you can see and read signs to navigate the world around you. People who are visually impaired don't always have that ability. OrCam has a pretty amazing solution with the OrCam MyEye, and they're teaming up with soccer star Lionel Messi to help promote it.
