Bradley C.wrote a review of Costa Harpoon Polarized Sunglasses - Costa 580 Glass Lens on September 24, 2009
By far the best sunglasses I have EVER worn. I have the Green Mirror 580 lenses and they are perfect. If it is super bright outside or overcast and gloomy these lenses give the perfect view. Anytime someone tries them on they are blown away by what they see. Do not hesitate to buy these!!
