Electronic Contact Lens Displays Pixels On the Eye
An anonymous reader writes "The future of augmented-reality technology is here — as long as you're a rabbit. Bioengineers have placed the first contact lenses containing electronic displays into the eyes of rabbits as a first step on the way to proving they are safe for humans. The bunnies suffered no ill effects, the researchers say."
Read the article - contact lens is a fresnel lens
From TFA comment:
To focus the light on the rabbit's retina, the contact lens itself was fabricated as a Fresnel lens - in which a series of concentric annular sections is used to generate the ultrashort focal length needed.
A somewhat older but more detailed article.
First time my butt... http://www.sciencedaily.com/releases/2008/01/080117125636.htm 2008, with photo of an even more complex working lens, on a rabbit's eye. From Slashdot, http://science.slashdot.org/story/08/01/17/1921217/bionic-contact-lens-may-lead-to-overlay-displays and http://science.slashdot.org/story/09/09/01/1619248/augmented-reality-in-a-contact-lens from 2008 and 2009, respectively. Took a while to sort through all the google echos of this being the first time, to get to the older pages where it had already been done. Though it is comforting to know that even more people are working to help create our soon to be our Human-Rabit hybrid Cybernetic overlords, whom I, for one, will welcome.
Question reality.
