Sony patents contact lens that Records With Blink Of An Eye

Sony patents contact lens that records what you see. It can be controlled by the user’s deliberate blinks, recording video on request.

Patent reads “Provided is a contact lens including: a lens unit configured to be worn on an eyeball. An image pickup unit configured to capture an image of a subject. The image pickup unit being provided in the lens unit. An image pickup control unit configured to control the image pickup unit.”

“It is known that a time period of usual blinking is usually 0.2 seconds to 0.4 seconds, and therefore it can be said that, in the case where the time period of blinking exceeds 0.5 seconds, the blinking is conscious blinking,” says the patent application.

The lenses would be fitted with miniscule piezoelectric sensors. It can measure changes in pressure, acceleration, temperature, or force by converting them to an electrical charge. These sensors would read the eye movements of the user, and turn the recording on.

Lens uses electromagnetic induction process to get enough power, to sustain the recording. A conductor is forced through a magnetic field to induce a modest electrical current. It can also adjust for the tilt of the wearer’s eye, and apply autofocus when things get blurry.

“Sony’s patent likewise describes a display showing additional controls that can be activated by a ’tilt sensor’,” Rhodi Lee reports for Tech Times. “The lens may even feature aperture control, autofocus, and image stabilisation to address the blur caused by the eyeball’s motion.”

Recently, Samsung has also filed a patent for, details a photo lens that also projects images onto the eye. Google is in the game as well. After the failure of Google Glass, Google is ready with contacts that would monitor diabetics’ blood sugar via their tears.

At this point, this technology cannot be comfortably embedded in a contact lens. So it’s only on paper for now.
