I got these Oliver Peoples Blondell aviators at an OP warehouse sale in Soho for only $125. They retail for over $400 USD! The lenses are polarized and protect my eyes 100% from UVA/UVB rays. They are super light too. These are probably the best actually-functional designer sunglasses I have ever bought and possibly the cheapest! They definitely saved my eyes from snow blindness while we were in the Berkshires. I barely squinted.
