Google really likes your eyes. It pioneered smart glasses with Google Glass and smart contacts with glucose-monitoring lenses. Now the California firm is taking things one step further by developing technology that actually goes inside your eyeball.

The tech giant recently filed a patent for an intra-ocular device that can connect to wireless devices, take photos, and automatically adjust the eye's focus. The one drawback is that it requires surgery to be implanted.

The patent, approved by the U.S. Patent and Trademark Office last week, describes "an electronic lens that can be controlled to control the overall optical power of the device."

The procedure to install it involves removing the natural lens, sucking up any fragments from the lens capsule—the clear membrane that surrounds the lens—and then injecting fluid into the capsule to accommodate the electronic lens.

Google claims the lens could be used to help people with vision problems like myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism (distortion of the cornea or lens), while an inbuilt antenna would allow the device to be charged wirelessly through specialized eyeglasses.

The antenna would also be used to send and receive information about the lens, allowing someone to calibrate it without the need for further surgery.

In the patent, Google acknowledges privacy concerns about how the device communicates with its surroundings, but the company says all communications would be encrypted.

Google was not immediately available for comment on whether it plans to develop the patent further.
