Back in 2009, we wrote about a contact lens in the works that displayed visual feedback right before your eyes, Terminator style. Well, two years and a few months later, Professor Babak Parviz has a working model. He has given the new lens to rabbits, and reports complete success.

The device's display has only one pixel, but serves as a working proof-of-concept for developing more complex information lenses. A useful device would need hundreds of pixels at least, to display a short email or text message.

The lens harvests energy from an external source using an antenna and has an integrated circuit to store the harvested power and transfer it to a transparent sapphire chip with a single blue LED. Unfortunately, while the range of the display was about one meter in free space, that range was reduced to about two centimeters when it was placed on the eye.

Another of the challenges facing the creation of a Terminator-style eye display is that the minimum focal distance of a human eye is only a few centimeters. This means that information displayed on a contact lens would appear blurry. To address this, the researchers used thin Fresnel lenses to magnify the display.

More research is needed before we'll be able to read text on our eyeballs though. "We need to improve the antenna design and the associated matching network and optimize the transmission frequency to achieve an overall improvement in the range of wireless transmission," said Parviz, co-author of the study. "Our next goal, however, is to incorporate some predetermined text in the contact lens."

New-Generation Contact Lenses Could Send Data from Internet Right to Your Eyes



Nearly everyday we can witness the appearance of new computers that are smaller in size than their predecessors. A lot of people around the world use their smartphones to surf the web, play games and use a myriad of applications, either for entertainment, business or both.

In case such trend continues to progress, in the future we could witness the appearance on the market of contact lenses that can project the user's emails right onto their eyeballs.

A group of researchers at Washington University has recently carried out tests of a new-gen contact lenses that can make it possible for their wearer to read emails and augment their vision with various data collected from the Internet.

The circuits inside the lenses are made of layers of metal that are just a few nanometers thick and include light-emitting diodes that are 1/3rd of a millimeter across.

But researchers still have to think about ways to supply power to these lenses. The lenses that have been tested work only in case there are several centimeters away from a wireless battery. There re also other issues that the team has to solve, like those linked with toxic chemicals.

The lead researcher, Prof. Babak Parviz, said that at the moment the team has the goal of incorporating "some predetermined text in the contact lens".

According to researchers, in future their lenses could show complex holographic imagery - price comparison data, for example - when the user will look at a particular product.

Such invention could be widely used in medical field and home entertainment.
