I saw these in a music video, so I did some searching. They're Carrera 6630's, and I love everything about them. Metal hinges, white-to-clear gradient frames, silver-mirrored grey-to-clear gradient one-piece lens. I scored a pair for $100 on ebay, they retail for quite a bit. However, I just found these for under $60 with free shipping! If you want to step it up and get some real shit, these sunglasses are perfect for you.
Here's a pic of me holding a baby squirrel.
Here's a video of someone modeling them.
They have them in blue, pink, and purple as well, here's the blue, they cost $81 though.
