Spend time in or around the water? The Costa Del Mar sunglasses with the classy Hammerhead frames are perfect for the aqua enthusiast. The polarized lenses of the Costa Del Mar prevent scattered light rays from passing through which translates to no glare for you! If you’ve ever tried to navigate into the sunset or fish in those dawn hours you know how brutal the glare off the water can be. Increase contrast and clarity while reducing strain on your eyes due to squinting against the low angle reflections either on the water or the road.
