Named after the small, chilled-out town in the Sea of Cortez, the Costa Loreto sunglasses are full frame and adventure friendly. Whether it's hanging on the coastal cliffs for which these Costa men's or women's sunglasses get their name or on any adventure on land or sea, these durable, versatile, polarized sunglasses can handle their own for any explorer.Costa 580G Lenses
Beyond Polarized - Costa 580 lenses were designed by in-house light spectrum experts to enhance colors because standard sunglass lenses fell short. The lens' multipatented technology manages light by absorbing harmful high-energy blue light (HEV) to cut haze and blur for greater clarity. In addition to 100% protection from UV light, 580 technology also absorbs HEV light known to cause mascular degeneration, pterygium, cataracts, and other eye diseases. Enhances reds, greens, and blues by blocking harsh yellow light at 580nm on the visible light spectrum boosts the amounts of red, greens, and blues naturally, enhancing colors and contrast. Filtering out harsh yellow for enhanced color, sharper contrast, and higher definition.Choosing A Lens Material
From day one, our lenses have set us apart. All Costa lenses have 100% UV blockage for maximum protection and 100% polarization to kill reflected glare. Our 580 technology goes beyond polarization to produce the clearest lenses on the planet. It selectively filters out the harsh yellow and harmful high-energy ultraviolet blue light, making colors brighter and objects appear more defined. So no matter what you are doing under the sun, you'll see it in stunning detail.
Glass lenses are best for situations that require ultimate clarity, and our plastic lenses are more cost effective while being more durable for more demanding applications without sacrificing clarity.Choosing A Lens Color
Light conditions are constantly changing. To get the most out of Costa Lenses, it's important to choose the right color. We offer seven lens colors that range from low-light like dawn to extremely bright light with blinding glare.
For offshore, blue mirror is the way to go. For freshwater and inshore, green mirror and copper are great options. For low light at dawn or dusk, sunrise is perfect. Gray lenses are the best choice for everyday activities. Of course, the best way for you to decide is to consider your environment.Frame Qualities and Options

About Costa Del Mar
1983: Born on the WaterWe build the clearest sunglasses on the planet for those who live to be on the water. Born on the water and we're still inspired by it. We want to be on 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 globe and battling extreme elements came to realize that the sunglasses they were relying on weren't as hardcore as their adventures. Seeing the world in absolute clarity and protecting their eyes was a must. So when they couldn't find worthy sunglasses, they decide 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. And the patented technology like those found only in Costa lenses and frames are proof that we're succeeding.Backed For Life:We stand behind our craftsmanship with a rock solid Limited Lifetime Warranty against manufacturer's defects.
