"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a assistant professor of electrical engineering, University of Washington in Seattle. This simply means that you would possibly see anything that is projected on to the display of your contact lenses along with the natural objects that we see on the world outside..such as in science fictions. Surprising..isnt it?
Well…UW engineers have already developed a prototype of this amazing device and have already tested on rabbits for any adverse-effects. The results were truly encouraging —no adverse effects were produced by the rabbits after testing for up to 20 minutes.
The lens comprises of an electric circuit as well as red light-emitting diodes for a display. As this still a prototype the display does not light up yet. “A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational ‘fairly quickly’ ” according to Parviz.
In order to develop a safer devise with no adverse effects for eyes, engineers have used flexible organic materials to build up its electronic circuits. A method called microfabrication technique known as self-assembly has been used to set its tiny electronic components in the correct positions within the circuit. Designers of the devise say that these components will not affect the lens-wearers vision as they entirely occupy the positions outside the transparent region of the eye.
Still, researchers are continuously working on the devise in order to place further improvements to enable wireless communication, and to power up the lens using radio-frequency power and solar cells.
