LED mounted in a contact lens for possible virtual / augmented reality displays

Every so often, internet news aggregator sites run a story about a research group that put an LED into a contact lens, then inserted it into a rabbit's eye.

I was hoping the lenses would stick to each other, but they did not, so I ended up fixing the edges together by pinching the plastic together with hot tweezers. This held well enough to capture a minute of video with the LED illuminated in my eye. For video purposes, I mounted the LED facing outward. An actual VR/AR display would have the LED facing inward.

Well, you wont catch me putting that thing in my Eye!:O But, he really knows his Electronics!:) I wonder how bright that LED Flashing was to him? He didn't mention that.
