Night-vision contact lenses developed

Scientists have invented a working night-vision device that is small enough to fit inside a contact lens.
Previous attempts to produce working night-vision functionality on a tiny scale using traditional methods had proven ineffective because the technology could only absorb a small percentage of the light. To get around this problem, scientists at the University of Michigan went back to the drawing board and developed a whole new way to detect light.

"The challenge for the current generation of graphene-based detectors is that their sensitivity is typically very poor," said Professor Zhaihui Zhong. "It's a hundred to a thousand times lower than what a commercial device would require."

The new and improved version of the detector uses two layers of graphene with an insulating barrier layer between them. By running a current through the bottom layer the device is able to realistically compete with the sensitivity of existing night-vision devices but on a much smaller scale.

"If we integrate it with a contact lens or other wearable electronics, it expands your vision," said Zhong. "It provides you another way of interacting with your environment."

Thieves and poachers are gonna have a field day (or night in this case) if this becomes publicly available.

I can see a lot of applications for this. It would be cool if they figure how to make it switch modes from light to dark so they can be worn in multiple environments.

Short of a perfect solution, but strong light problem can overcome by wearing a single lens.

I wouldn't bother them. That sounds like a environmentally friendly solution!

It's just the fact that they make such a damn mess.
