Experience a world of amazing color, contrast and clarity through a pair of Costa Del Mar sunglasses. The exclusive WAVE 580™ lenses are the most advanced glare-beating, polarized sun lenses. They eliminate much of the yellow light that can negatively affect vision. Your eyes will see more red, blue and green, resulting in purer vision, deeper colors and sharper contrast. Embedded UV protection in all lenses blocks 100% of the sun's harmful rays, and it will never wear off over time, unlike the coated protection found on some sunglasses. Exclusive lifetime warranty.
