> The article does not claim that the glasses prevent face detection.
Their first image seems to be showing the difference between detecting and not detecting a face ("Facebook detects a face" and "No face detected").
Comments like this, too:
"They claim to break face detection when the lights are on."
So I assumed they were claiming it breaks face detection.
Face detection - determine the location of a face or faces in an image.
Face recognition - given a location of a face in an image, correctly predict who's face it is.
