Google just can’t get out of the optical biz. First Glass, which is slated for a relaunch in 2015. Next the collaboration for Smart Glucose Monitoring Contact lens in conjunction with Alcon The latest is the patent of Contact Lenses the use the iris as a biometric fingerprint.
Google wrote: “In one implementation, the contact lens can include: a transparent substrate formed to cover at least a portion of an iris of an eye and a circuit. The circuit can include: one or more light sensors disposed on or within the transparent substrate that detects light filtered through the iris and incident on the one or more light sensors; readout circuitry, operably coupled to the one or more light sensors, which outputs information indicative of the light filtered through the iris and incident on the one or more light sensors; and a power component that supplies power to the readout circuitry. In various implementations, the contact lens can be employed in systems and/or methods associated with authentication and identification.”
