Augmented Reality Coming to Your Contact Lenses?

Researchers at the University of Washington and Aalto University in Finland have created a new type of contact lens that can contain electronic displays with augmented reality capabilities. The creators of the technology hope that it will one day be used in realer-than-real video games.
Crazy, right? Well, so far the tech has only been used on rabbits. But the scientists believe these lenses will soon be safe for humans as well.
How do they work? The contacts feature a tiny antenna that will pick up power from an external source and then relay information to each lens.
For now, though, the power source must be impractically close to the lenses. (Can you say 2 cm?) And there's still work to do on the thinness of the lenses. After all, augmented reality images on each lens would be viewed (obviously) at an extremely close distance. How will the researchers compensate for such a shallow depth of field?
With these challenges, it seems that your contact lenses may remain relatively low-tech for quite a while. But it's certainly a fascinating thought. Want to delve into the topic further? Read more here.
