The only time I have seen them I also heard a woman say "are those camera glasses, don't film my kid"

"they're not on" He muttered. He looked so annoyed and full of contempt. But, no one seemed to take his side. The train just stared at him waiting to see what would happen. The guy took them off. He sighed dramatically. It was very funny.

This was on the 4 train almost two months ago.
