Sony is now developing contact lenses that can record videos and play it back. It was controlled by deliberate blinks by the user. Sony wants to look outwards rather than in. A new patent, awarded to the company in April. Sensors embedded in the lens are able to detect the difference between voluntary and involuntary blinks. The image capture and storage technology would all be embedded in the lens around the iris, and piezoelectric sensors would convert the movements of the eye into energy to power the lens. It also features autofocus and zooming capabilities. It also has inbuilt storage that allows you to access the recorded images and videos within the lens. The lens could also feature night vision and thermal imaging. Other smart contact lenses are focused on improving vision or providing an augmented reality HUD, but Sony wants to look outwards rather than in. The patent claims that“It is known that a time period of usual blinking is usually 0.2 seconds to 0.4 seconds, and so it can be said that in the case where the time period of blinking exceeds 0.5 seconds, the blinking is conscious blinking,”  Further, users can select deliberate eye movements for actions like playing a video.
