“[Japan’s] National Institute of Informatics said it has developed eyeglasses that help users protect their privacy by disabling facial-recognition systems in cameras.
The Privacy Visor [ . . . ] uses unique angles and patterns on its lens that reflect or absorb light. This prevents the recognition systems in digital cameras and smartphones from spotting a human face in a shot and focusing on it.
Tests with cameras on smartphones showed that the eyeglasses were able to trick the facial-recognition system 90% of the time.
The Privacy Visor is scheduled to go on sale by June 2016 and is expected to cost about ¥30,000 ($240).”
