These are gorgeous, dark, and my bestie said they look like private security guard shades.  The image shown on the Amazon site looks more like green lenses, but I went by the description which said "polarized grey" and they were.  The frames are a nice matte black and the gray lenses look quite dark.  It's a challenge to see the person's eyes while they are wearing them.  I asked my 10 year old son to try them on, I've attached the pic.

I'm no expert on real/fake glasses, but I've owned enough "expensive" shades to be able to put them on and know when I have quality shades.  These were a very clear and sharp look, and very comfortable.  The world was bathed in a light grey.  There is a big "P" on there next to the Ray Ban logo, which I don't love, but I do love the price on these (it's a very good price for polarized shades, which makes me suspicious!).
