Costa Del Mar Blackfin Matte Gray Frame Performance Polarised Glass Lens Sunglasses Costa Factory Store

You might have gallons of brine in your face and 600 pounds on your hook, but these sunglasses still won’t slip. 

The Hydrolite™ co-injected lining takes care of that, and the flexible frame means serious comfort. Blackfin pushes the edge in sunglass performance–so you can push it everywhere else.

Costa 580 lenses were designed by in-house light spectrum experts to enhance colours because standard sunglass lenses fell short. The lens’ multi-patented technology manages light by Absorbing Harmful High-Energy Blue Light (HEV) and cuts haze and blur for greater clarity.

In addition to 100% protection from UV light, 580 technology also absorbs HEV light known to cause macular degeneration, pterygium, cataracts and other eye diseases.
