Review on Costa Del Mar Blackfin Sunglasses Men's Accessories by Mike Barnes

NO Glass Lenses. Numerous reviews say so, but they are poly/plastic. Point. There is no built-in spring mechanism for the earbuds. For the money you should get this. BUT water and air sports optics are second to none. Put them on and go surfing, boating or flying, and you'll be sure no ambient light gets around the corners, and the perfectly polarized, non-reflective lenses let you see everything in detail. They're expensive, but worth it. . Recommended and wish they had real glass lenses, but they're damn good sunnies that don't necessarily need a leash to keep them upside down in the water (although one is recommended if you really go surfing or swimming).
