According to Isao Echizen, a professor at the National Institute of Information Research in Japan, the "privacy-protected" lens uses 11 LEDs in the near-infrared band. When the wearer is photographed, they will emit near-infrared rays that are invisible to the naked eye to the camera of the Google glasses, causing the camera to be unclear due to excessive light, and thus unable to recognize the face. 
He pointed out that wearing ordinary sunglasses does not prevent the face recognition function of Google glasses, because the facial features of the person include other parts such as eyebrows and nose, and only cover the eyes and escape the misfortune of the face recognition by smart devices such as Google glasses. .
