Contact lenses when connected to the Internet could help read emails and text messages, claim scientists.

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 before your eyes.
Till now such technology has only been seen in science fiction like 'The Terminator' films and in 'Dr Who' spin-off 'Torchwood'.
The researchers said that 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 the user's body to provide up-to-date information on glucose or lactate levels, which could prove medically important, the Telegraph reported.
The contact lens created by the university researchers consists of an antenna to harvest power sent out by an external source, as well as an integrated circuit to store this energy and transfer it to a transparent sapphire chip containing a single blue LED.

To combat this, the researchers incorporated a set of Fresnel lenses into the device, which were much thinner and flatter than conventional bulky lenses, and were used to focus the projected image onto the retina.
