The glasses are very lightweight, meaning they are not overly sturdy.  What do you expect at this price?  They really are polarized, and look pretty good... but the piece over the bridge of the nose is short. VERY narrow. If I'd tried these on in the store, I would not have bought them. I love big glasses and have a pretty big head admittedly, but I do have a lot of designer sunglasses and none of them have a bridge this small.  Just be warned.
