The completed contact lens system
The idea of having images and text streamed live across your contact lenses has been used in many a Hollywood film. Now an international team of researchers has developed the first working prototype for such a device – they have constructed and tested a prototype contact lens capable of streaming real-time information across the field of vision; potentially providing the wearer with information updates. The researchers claim that their device will have a variety of uses, such as a biosensor, augmented reality systems, gaming devices, navigation systems and even as an aid to the hearing impaired.
In a study published in the Journal of Micromechanics and Microengineering, the researchers from the University of Washington, Seattle, and Aalto University in Finland describe how they constructed a computerized single-pixel contact lens and then demonstrated its safety by testing it on live eyes that showed no adverse side effects.
