Product overview
  
  Premium Polarized 580 Lenses*
Filtering reflective glare is essential for anyone on the water or outdoors. We sell only polarized sunglasses.
100% UV Protection
Your Costas absorb 100% of UV light, providing you the best in light management and protection.
Scratch Resistant and Durable
The C-Wall coating provides extra scratch-resistance and a barrier that repels water, oil and sweat for easy cleaning.
Inspired by the form and function of nature’s beauty, it’s no coincidence the Aleta sunglasses get their name from the Spanish word for “fin.” Offering water-ready performance in a stylish yet functional design, Aleta uses lightweight Bio-Resin and double-injected Hydrolite™ for a better grip. And with micro shields and hooding, excess light stays out while fog stays down with vented nose pads. Wearing Aleta, you’ll see the smooth shape and refined lines that don’t just stop at style. They’re best enjoyed when on, in and near the water.

How to choose lens material
From day one, our lenses have set us apart.
All Costa lenses have 100% UV blockage for maximum protection and 100% polarization to kill reflected glare.
                            Our 580 technology goes beyond polarization to produce the best lenses on the planet. It selectively filters out the harsh yellow and harmful high-energy ultraviolet blue light, making colors brighter and objects appear more defined.
So no matter what you are doing under the sun, you’ll see it in stunning detail. Glass lenses are best for situations that require ultimate clarity, and our plastic lenses are more cost effective while being more durable for more demanding applications without sacrificing clarity.
