These will put a computerised layer over the real world.

A company in the USA called Mojo is developing augmented reality (AR) contact lenses. Although there is no concrete news about exactly how these will work, it is safe to say that the idea of these AR devices is that they will add a computerised layer over reality. This can help to identify objects in front of you. It might also be able to display notifications in a type of heads up display. Many companies, like HP and LG have already invested in this startup.
