These are a heck of a pair of sunglasses! I just wish they would have fit my face and I would not have returned them. Alas they did not fit and the "arms" over the ear rode too high over my ear thus leaving the glasses with too much of a gap for sunlight to "leak" in on the eyes. Other than that, they were a very nice pair of shades.
I’ve worn costa for over 25 years! Wouldn’t fish without them! The 580G glass has the most clarity and glare reduction of any sunglasses I’ve ever tried!
