Costa Blackfin Blue Mirror 580G

Light conditions are constantly changing. To get the most out of Costa del Mar lenses, it's important to choose the right color. We offer six Lens Colors ranging from low light like dawn to extremely bright light with blinding glare. From day one, our lenses have set us apart. All Costa del Mar lenses have 100% UV block for maximum protection and 100% polarization to make reflected glare disappear. Our 580 technology goes beyond polarization to produce the clearest lenses on the planet. Selectively filters out harsh yellow and harmful high-energy ultraviolet blue light, making colors brighter and objects appear sharper. So no matter what you're doing in the sun, you'll see it in amazing detail. Glass lenses are best for situations that require maximum clarity, and our plastic lenses are more cost effective and are more durable for more demanding applications without sacrificing clarity. We build the clearest sunglasses on the planet for those who live to be on the water. We were born on the water and we still get inspired. We want to be in it, we want to protect it, and we want to inspire others to do the same. In 1983, a group of hardcore fishermen who spent their days exploring the world and battling extreme elements realized that the sunglasses they trusted weren't nearly as intense as their adventures. Seeing the world with absolute clarity and protecting his eyes was a must. So when they couldn't find decent sunglasses, they decided to build their own. And Costa was born. After all these years and all these adventures, our mission has never wavered: to create the clearest sunglasses on the planet for life's great adventures.
