Costa Del Mar sunglasses are incredible! They are available with polycarbonate or glass lenses.  Both are polarized and provide awesome visibility….especially while on the water or fishing. Look at the water without Costa sunglasses on and then look at the same water with the sunglasses on. This should immediately show the value of Costa sunglasses. It’s very apparent in the Caribbean and similar environments, where there are different colors in the water. These sunglasses make the multiple colors of the water more visible and more sharp in my opinion.
