Wireless display in a contact lens takes shape. The researchers from the University of Washington and Aalto University, Finland, have constructed a computerised contact lens and demonstrated its safety by testing it on live eyes.

Wireless display in a contact lens takes shape

At the moment, the contact lens device contains only a single pixel but the researchers see this as a "proof-of-concept" for producing lenses with multiple pixels which, in their hundreds, could be used to display short emails and text messages right into the eye. The contact lens consists of an antenna to harvest power sent out by an external source, as well as an integrated circuit to store the energy and transfer it to a transparent sapphire chip containing a single blue LED. The device could overlay computer-generated visual information on to the real world and be of use in gaming devices and navigation systems.

It could also be linked to biosensors in the user's body to provide up-to-date information on glucose or lactate levels. OptiTex. 3d Augmented Reality Solutions | Holition.
