Google Glass, a wearable headset that projects a computer interface over a user's field of vision, has been hailed by techies and civilians alike as a potentially revolutionary invention. But the "augmented reality" that the device creates may soon be outdone by an even more amazing technological feat: electronic contact lenses.

According to MIT Technology Review, a group of researchers have been testing electronic lenses that outfit the user's cornea by mounting light-emitting diode on a normal, everyday contact lens. The researchers used graphene and silver nanowires to create the technology.

First tested on rabbits (who apparently have eyes similar in size to humans), the contact lenses did not have any adverse effects, even after five hours. The Review reports that the rabbits didn't experience irritation and that the electrodes on the contact remained electronically conductive, proving that they could possibly be used in flexible, wearable lenses for humans.

"Our goal is to make a wearable contact-lens display that can do all the things Google Glass can do," said Jang-Ung Park, lead researcher on the project. The team has been working with researchers at Samsung to test the electronic lens display, in hopes of coming up with a wearable product in the coming years.

As of right now, there are electronic lens displays on the market that monitor the eye pressure of glaucoma patients for 24 hours. And even Google Glass project founder Babak Parviz has built a contact lens display. But neither of those inventions have used soft, transparent materials in its production.

While electronic contact lenses are still in their beginning stages, Google Glass could be released as early as this year. Glass is capable of searching things on Google, recording videos, taking photos, and showing reminders. The technology will transform the way its users interact with the world around them and may even offer some health benefits.

Google Glass could enhance surgery by allowing surgeons to operate with simultaneous access to imaging and patient data. It can also track your diet, find healthy recipes, and tell you how many calories are in the food you're eating. And it can even store important prescription medicine information and give users medical feedback from specialists.

If researchers are right, the revolutionary nature of Google Glass will soon pale in comparison to electronic contact lenses. Only time will tell.
