One of the uses discussed in Google's patent is giving a sense back to blind people. While a blind person couldn't gain sight from the contact lens, the camera could, for example, detect approaching traffic and then wirelessly communicate with another device the blind person was carrying. When paired with facial recognition software, the contact lens could identify a nearby person and transmit that information to an earpiece.
Right now, the patent is to secure future innovation and is not yet linked to a marketable product.
This isn't the first time Google has talked about putting a computer on an eyeball. Earlier this year, it announced development of a contact lens that checks tears for blood sugar levels and communicates with insulin pumps. These are just two of Google's contact lens patents; there are at least five more in the works.
