Imagine catching up with your texts, social networking and perhaps the news without having to log on to a computer or even glance at a smartphone. Messages and images would simply appear in front of your eyes, generated by a computerised contact lens. But until now the concept of info-vision had belonged to the realms of science fiction.
However, scientists have developed a prototype lens that could one day provide the wearer with all kinds of hands-free information. The lenses, which would be inserted and removed like normal contacts, could also be handy if you are indeed enjoying the great outdoors, allowing you to zoom in on distant views.
