Thinking about this makes my eyes hurt.
Researchers at the University of Washington and Finland's Aalto University have developed a prototype of a contact lens that would project digital images onto the retinas of its wearer. And, for the first time, they actually tested the lenses on live creatures - in this case, rabbits that underwent anesthesia.
That may seem like it's out of left field, but researchers for years have been working on the idea that we should somehow overlay digital information on top of the real world. Lots of smartphone apps, including Wikitude, Spyglass and Golfscape – as well as some prototypes for "Terminator" glasses - are trying to do this.
As these researchers noted this week in the Journal of Micromechanics and Microengineering, contact lenses that display digital information are the holy grail for this genre of reality-bending work. Eventually, projected displays from contact lenses could replace all the other screens we look at. You could end up reading your e-mail on your contacts. FULL POST
