I'm a grandmother who happened to notice that her 16 year old granddaughter was oohing and aahing over these glasses on Amazon.  When she left the computer I took the opportunity to order them for her as a surprise. When they arrived she was VERY surprised and pleased.  I believe I'm now the most awesome of grandmothers EVER, all because of these sunglasses, which look very cool on her.  I may not have the most up-to-date lingo to describe them, but I would highly recommend their purchase!
