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.
