The device would be controlled by consciously blinking in a certain way, prompting it to start or stop recording. Since the wearer blinks normally, effectively covering the lens for 0.2 to 0.4 seconds each time, the lens could automatically delete dark frames for better playback, Sony's patent explained.
An antenna in the lens allows for transmitting the captured images wirelessly, according to the patent. Those who need prescription lenses would wear a corrective lens in one eye and the recording lens in another. Sounds like another compelling point in favor of laser eye surgery.
Contact Lenses Could Send Texts to Your Eyes
As CNET noted, this is all theoretical right now, though. Sony's patent doesn't guarantee a comfortable contact lens that actually records. Many steps would need to happen first.
However, the regular contact lenses for corrective vision have been improving rapidly over the past few years, my ophthalmologist told me recently. Real recording ones might just arrive in the deliberate blink of an eye.
