Title: They actually work!
Review: I was very surprised that these glasses actually work. There's a mirror on each side, and they let you see behind your head. It's also hard to tell that they're spy glasses, because from the front, you can't tell any difference.The outer 40% of each side of the glasses has a mirror on it. I'm bald, so this worked very easily for me. I'm sure if you have really bushy hair, then it will get in the way.It takes a while to be able to retrain your brain to be able to actually do anything useful with these glasses. But it's probably a nice exercise.Pros:+You can actually see behind you+They look like regular sunglasses+Everyone should buy some of theseCons:-Not the most professional-looking glasses, but they are economical
