Costa Del Mar Blackfin 580P Polarized Sunglasses
The Blackfin from Costa Del Mar brings together the brand's most capable polarized lens technology with a frame engineered to stay put during any on-water or outdoor pursuit. Built by an American manufacturer with decades of focus on performance eyewear, the Blackfin is a no-compromise option for anglers, surfers, and anyone who demands optical clarity in bright, reflective conditions.
580P Polycarbonate Lens Technology
The 580P designation identifies Costa's polycarbonate lens platform, the foundation of the Blackfin's optical performance. The 580 lens filters yellow light at the 580-nanometer wavelength, which sharpens contrast and reduces glare on the water while enhancing the blues, greens, and reds that matter most outdoors. The result is a cleaner, more defined view in harsh sun.
Polycarbonate construction keeps the lens lightweight and impact-resistant without sacrificing clarity. 580P lenses meet ANSI Z87.1 impact standards, making them well-suited for active use where weight and durability both matter. The mirror coating on the outer lens surface provides an additional layer of glare reduction in the brightest conditions.
Global Fit Frame
Costa's Global Fit geometry is designed for a broader range of face shapes, particularly those with a lower nose bridge or higher cheekbones. The wider nose pads sit flatter and more securely, preventing the frame from sliding and keeping the lens correctly positioned in front of the eye. If standard sunglass frames tend to rest on your cheeks or sit at an angle, the Global Fit frame solves that fit problem without requiring adjustments.
The Blackfin frame is built from TR-90 nylon, a lightweight thermoplastic that holds its shape in heat and resists warping when exposed to saltwater and sunscreen. The co-injected rubber on the temple tips and nose pads locks the frame in place during active use.
Polarized Protection
All Costa 580P lenses are 100% polarized and block 100% of UVA, UVB, and UVC rays. The polarization layer is fused within the lens rather than applied as a surface coating, so it does not peel or degrade with normal use. This construction keeps glare elimination consistent over the life of the lens.

Frequently Asked Questions
- Are Costa Del Mar Blackfin sunglasses polarized?
- Yes. All Costa 580P lenses are fully polarized. The polarization filter is fused into the lens construction, not applied as a surface coating, so it provides consistent glare elimination and does not peel or wear off with normal use.
- What does 580P mean on Costa sunglasses?
- 580P identifies Costa's polycarbonate lens platform. The 580 refers to the lens filtering yellow light at 580 nanometers, which sharpens contrast and enhances color definition outdoors. The P stands for polycarbonate, meaning the lens is lightweight and impact-resistant. Costa also makes a glass version (580G) for those who prefer glass optics.
- What is the Costa Global Fit frame?
- Global Fit is Costa's frame geometry designed for faces with a lower nose bridge or higher cheekbones. The wider, flatter nose pads provide a more secure, level fit for people whose face shape causes standard frames to slide or tilt. If typical sunglasses rest on your cheeks rather than your nose, a Global Fit frame is worth trying.

- How do I care for Costa Del Mar 580P lenses?
- Rinse the lenses with fresh water after saltwater or sunscreen exposure. Use a microfiber cloth to clean the lens surface -- avoid paper products or clothing, which can cause micro-scratches over time. Store in the included case when not in use to protect the mirror coating.
