Wireless contact lens to provide hands-free information

In today's high tech world, gadgets like smartphone, ipod, ipad,  tablets and any other Android Gadgets are common, which help us to access web information very easily. What if our contact lens show us emails? Na! i am not talking about James bond's movie!

Aalto University, Finland and the University of Washington have created a prototype contact lens that could provide hands-free information updates to the wearer.
a computerised contact lens have been constructed and demonstrated by researchers to make sure its safety by testing it on live eyes. and found no signs of adverse side effects.

For now, these contact lens device contains only 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.

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.

The contact lens consisted 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.

But human eye has focal distance of several centimetersand cannot resolve objects on a contact lens, this makes projected information blurry.To combat this, the researchers incorporated a set of Fresnel lenses into the device; these are much thinner and flatter than conventional bulky lenses, and were used here to focus the projected image on to the retina.


Its an example how technology is improving day by day. It is awesome idea by using contact lenses we can view the internet infront of our eyes.

It's great usage of contact lenses by technology.
