DEMANDING. UNCOMPROMISING. These two words describe the wild we love and the way we work. Our search for all things new and undiscovered never ends, taking our technology to a new level every day. We test our gear in the same conditions you live and play in. We fish. We paddle. We explore. And most importantly, we learn. The result is lenses that let you see a school of reds on the flats, spot a sailfish 50 yards behind the boat ten feet under the surface, and sunglasses that feel comfortable from dawn to dusk. COSTA 580 TECHNOLOGY - High-tech. High-Performance. The ultimate lens. Yellow light is the enemy. It's hard for the eye to process and changes how you see the world. Not with a pair of 580s on. These patent-packed lenses raise the red, blue and green areas to amazing levels, while eliminating much of the yellow light. The result is purer vision, deeper colors and sharper contrast.
