Sony patents contact lens that can take photos and video

Sony has filed a patent that could put Google’s Glass to shame. Its patent is for smart contact lenses that could be capable of capturing photos and video.

When the wearer blinks, the lens snaps a photo, which is then sent to a device such as a smartphone, tablet, or computer. But it won’t capture an image when it detects any old blink; it has to be a more purposeful blink than normal.

The patent application reads, “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.”
