Google takes several years devising new models of smart contact lenses that allow us to use augmented reality without glasses, but the new patent extends beyond with lenses with iris scanner.
In the past Google agreed with Novartis to create a patent quite futuristic of camera lenses; instead the patent granted to Google, it goes in another direction, to allow authenticate with your eyes. As you know, fingerprints are not the only method of biometrics, to identify ourselves with our body; iris scanner can be more accurate and safe (although there are other interesting developments using our brain waves that have more potential).
However, authenticated by the iris can become complicated and depends on the quality of the cameras; if you really want to become a popular method you need a way we can use our iris almost without us noticing. This is where this patent comes on contact lenses with light sensors on its surface that capture the light reflected in the iris; the image obtained is compared with the stored on the computer system where we want to authenticate, and if it fits perfectly then we gain access.
The patent has few specifics on how these lenses would work, and that's where the challenge is, because they not only have to get the image of our iris but also transmit wirelessly to the system. One can imagine that this patent has been applied for the safe side for future developments, although as we know not all patents become products.
