Google files patent for eyeball device that uses 'energy harvesting antenna'

Google has been known to work on a smart contact lens to assist people with diabetes by measuring glucose levels, but now, based on a patent filing, it appears to be working on a device that would be inserted into the eye to improve vision.

Spotted by Forbes, the patent filing shows how an electronic lens would assist in the process of focusing light onto the eye's retina. The planned device injected into the eye contains a number of tiny components: storage, sensors, radio, battery and an electronic lens, according to the publication. The eyeball device gets power wirelessly from an "energy harvesting antenna." 

The patent describes what looks like an external device to interface with the eyeball computer, and the two would communicate through a radio. No word on when it'll be ready for prime time. Article
