they are creep glasses with hidden cameras that record people in public and can use AI to identify people and find their social medias and shit at a glance.
supposed to have an LED that indicates when the cameras on, but there is a big underground industry of disabling the LED without disabling the camera so creepers can record without people knowing.
also facebook gets a copy of everything you see and do, which is especially problematic in bathrooms, in doctors offices, etc.
Big creepy pervert stalker stuff.
