There was a short film I saw that predicted the use of #PervertGlasses. It's about a guy seducing a girl on date, and he makes all the right decisions because he's hooked his glasses into her social media (mainly Facebook). We see it from his point-of-view, and how the glasses provide him with all the info. It's very creepy.

It was made about 15 years ago, and was pulled a few weeks after I saw it. People found it too creepy...

And yet, here we are.
