You could soon read emails on your contact lenses

The scientists are trying to convert this imagination into reality. An international team which claims to have developed a prototype lens that could potentially provide the wearer with hands-free information updates. This imagination is possible by futuristic technology.

The scientists from Washington University in the US and Aalto University in Finland have constructed a computerized contact lens and demonstrated its safety by testing it on live eyes, and there were no signs of any bad side effects.

At the moment, the contact lens device contains only a single pixel, but the team sees this as a "proof-of-concept" for producing lenses with multiple pixels which, could be used to display short emails and text messages right before one's eyes.

The contact lens created by the scientists consist of an antenna to harvest power sent out by an external source, as well as an integrated circuit to store this energy and then transfer it to a transparent sapphire chip containing a single blue LED, 'The Daily Telegraph' reported. 

One major problem the researchers had to overcome was the fact that the human eye, with its minimum focal distance of several centimetres, cannot resolve objects on a contact lens. Any information projected on to the lens would probably appear blurry.
