Costa are universally recognised as the best polarized fishing and watersport sunglasses available. Most polarized sunglass lenses eliminate glare by blocking reflective light, but Costa sunglasses’ patented 580 lens technology goes a step further by blocking the perfect amount of harsh yellow light and harmful blue light while enhancing reds, blues and greens: the result is less haze, less blur, greater contrast and greater clarity. Probably the best polarized lenses ever created.
