Contact lenses of today predominantly
serve two purposes. They sharpen your vision, correcting long or short sightedness or they change the appearance of your eyes turning them into cats eyes, different colours or even smiley faces. Think that’s pretty cool? Then you will love the contact lenses of the future. With a technology called “wearable computing” users will be able to see an overlay of computer generated visual information through the contact lenses. Being reminiscent of the Terminator movies, wearable computing contact lenses may be able to send and receive data from other platforms such as mobile phones, GPS units or gaming units. They could also potentially inform the user of current events and real time notifications plus provide health alerts and even help the user navigate through a city.
The research is being driven by Professor Babak Parviz of the University of Washington and his pupils (sorry bad pun) in conjunction with scientists from the University of Aalto in Finland. Their research was recently published in the journal of Micromechanics and Microengineering.
At present the researchers have
successfully managed to create and test a single pixel contact lens on live rabbits eyes. The unit is powered wirelessly encompassing an antenna, radio circuit, transparent sapphire chip and micro light emitting diodes of which all are integrated onto a single contact lens. This single pixel contact lens can be used to perform simple operations. Before we are able to read emails using this technology, hundreds of pixel resolutions need to be incorporated which may be many years away.
A number of challenges and obstacles faced the team in the development of the Android contact lenses. Some of these were finding ways to power the wireless device, making it biocompatible and integrating all of the components onto such a small surface. Tests so far have been limited to the eyes of live rabbits. At present the unit can be powered from a maximum distance of 1 metre away and only 2cm away when it is being worn.
The wearable technology created by the team demonstrates that Android contact lenses can be produced in the future to serve a number of purposes. Perhaps in the coming decades, many of us will be looking through android contact lenses much like Arnold Schwarzenegger in the Terminator movies…Hasta La Vista Baby!

computers and tablets of the future may all be powered and cooled with liquid metal allowing processors to become many times more powerful than they are already.

like gestures as well as bending and twisting to control the handset. Perhaps some of the coolest features are the electro-tactile feedback which lets you feel images and the mood recognition software which can change the lighting backdrop on the interface when using video calls to represent emotion.
