Yikes, do we really want this, would this not be very intrusive.And next — the contact lens that lets e-mail really get in your face

The days of picking up a mobile phone to read a text message are numbered. In the future, all you’ll have to do is stare intently at a projected image in front of your eyes.

Researchers at the University of Washington have developed a contact lens with the potential to project a telephone display directly on to the retina.

The technology could allow any high-resolution image to be displayed in front of the eye. Eventually, games, documents and music collections could all be displayed in a user’s field of vision.

“We realised that we could make really tiny functional devices that can be incorporated into a contact lens to do a lot more than just improve vision,” Babak Parviz, Professor of Electrical Engineering at the University of Washington, told The Times. “Our goal is to integrate a display which can do everything that an iPhone or computer does now – but in front of your eye. A user could manipulate the document by blinking or by using his voice.”

By incorporating metal circuitry and light-emitting diodes into a polymer-based lens, the researchers created a functional circuit that is biologically compatible with the eye. Ultra-thin antennas, a few nanometres thick, are used to transmit information wirelessly to the outside world.

The lens, which is as thin and as comfortable to wear as an ordinary hard contact lens, was created with two purposes in mind, its creator said. cont...
