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 580TM 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. Costa 580 lenses are available in gray, copper, blue and green mirrors, making them the perfect choice for any conditions.
COSTA 400TM Lenses.
Designed for adventure. Built to perform. 100% polarization. 100% UV protection. Unmatched clarity, contrast and definition. This is what you'll see through every pair of Costa 400 lenses. We built our reputation and our business on this lens, and it's made for anyone who lives on the water.
SOME SECRETS ARE WORTH PROTECTING.
When you've got cutting-edge tech like we do, you want to keep it safe. U.S. Patents 6,334,680 and 6,604,824 belong to us. Feel free to read them, but don't even think about trying to imitate this stuff. And don't bother looking for this stuff in anyone else's sunglasses either.
Lenses
The best lenses out there.
Only one thing should come between your eyes and adventures: the best lenses. Ours deliver amazing color, contrast and clarity, so you can see your world purely. Here's what we use to make them.
Glass:
The most optically correct lens material offering the purest vision. Our LightWAVETM glass lenses are 20% thinner and 22% lighter, and still exceed federal standards for impact resistance.
CR-39:
exceptional resolution in the most optically correct, lightweight and scratch-resistant plastic lens material out there.
Polycarbonate:
when we can't use CR-39 (like our frameless and interchangeable lens styles) we use this stuff. Ours is cast and hard-coated to make it as tough as possible.
580:
Vision redefined.Yellow light is the enemy, on the water and on land. Costa 580 lenses use patented technology to cut down on the yellow light, allowing the eye to see more red, blue and green. Simply put, they're the most advanced glare-beating polarized sun lenses on the planet, and they'll change the way you see, period. Performance is in the details, and here are the goods on 580:
The yellow light near 580 nanometers is particularly difficult for the eye to process - so we block it
they offer sharper contrast, better definition and enhanced colors in any environment
backed by U.S. Patents 6,334,680 and 6,604,824, so the other guys don't have it and can't touch it
available in gray, copper, blue mirror and green mirror.
