Augmented reality contact lenses feature prominently in the 2006 science fiction novel Rainbows End. The novel isn't really about the technical details of AR, but more about people living in a society in which they're able to construct mutually exclusive shared imaginary "realities", or belief circles. In some ways it predicts the divisions brought on by social networks. Also features artificial intelligence and other near future technologies. It's written by Vernor Vinge, who wrote A Fire Upon the Deep, and its prequel A Deepness in the Sky.
