Scientists working on smart contact lenses -

Although Google Glass has yet to hit retail and flop, scientists are already working on next generation wearable devices and they include smart contact lenses.

One of the main problems facing Google Glass is its sheer bulk. The device is still pretty big, yet despite its size it doesn’t offer a lot of battery life. Scientists in Korea and Switzerland believe smart contact lenses, built using a new generation of nanomaterials, are the way to go.

A team led by Jang-Ung Park at the Ulsan National Institute of Science and Technology managed to mount a light emitting diode on an off the shelf contact lens. The team came up with a special material of their own to make it possible - a stretchy mix of graphene and silver nanowires, reports Technology Review

They tested their contraption on rabbits. The fluffy test subjects didn’t seem to mind, and did not rub their eyes. 

Meanwhile a Swiss team at Sensimed is working on a smart lens for 24-hour monitoring of eye pressure in glaucoma patients. Like the bunnies, they don’t seem to mind, either. University of Washington professor and Google Glass project founder Babak Parviz has also dabbled in contact-lens displays, but they were built using rigid, non-transparent materials.
