Protecting your eyes from the sun's rays can be a real challenge, especially on the water. Costa® polarized sunglasses have been purpose-built to excel in such conditions. Costa makes men's polarized sunglasses and women's polarized sunglasses because they understand that inshore and offshore anglers have to combat the reflective and refractive properties of water. And it takes premium fishing sunglasses to win that fight. Patented 580 technology enhances colors by blocking harsh yellow light and eliminates haze and blur by blocking blue light. 100% polarization kills reflected glare and reduces eyestrain, while 100% UV blockage provides max protection. Costa sunglasses feature stylish yet sturdy frames with lenses in 6 colors to help you see clearly in all light conditions. And whether you choose plastic (lightweight, impact-resistant, high clarity) or glass lenses (highest technology, scratch-resistant, highest clarity), you'll love the performance…and the view. Don't forget to check out Costa clothing for men and ladies, too! With their iconic "C" logos and a wide variety of colors and styles, Costa t-shirts and fishing hats are a great way to let other outdoor enthusiasts know you prefer Costa.
