The Costa Del Mar Blackfin 9014 polarized sunglasses have earned their reputation as a trusted tool for serious anglers and outdoor enthusiasts. Whether you're fighting marlin offshore, sight-fishing the flats, or simply spending long days on the water, the Blackfin delivers the clarity and all-day comfort that Costa built its name on.
Costa 580 Lens Technology: See What Others Miss
At the heart of the Blackfin is Costa's patented 580 lens technology. The "580" refers to a specific wavelength—580 nanometers—where yellow light creates visual noise and eye fatigue. Costa's lenses filter out this harsh yellow light while enhancing reds, greens, and blues, giving you sharper contrast and truer color in any condition. All lenses provide 100% UV protection and 100% polarization to kill reflected glare.
You can choose between two lens materials. The 580G glass lenses offer the best optical clarity available—20% thinner and 22% lighter than typical polarized glass, with scratch-resistant mirrors encapsulated between layers of glass. The 580P polycarbonate lenses are the most impact-resistant and lightweight option, ideal for active use. Both deliver the same color-enhancing 580 technology that helps you spot fish, read water, and stay out longer without eye strain.
Built for Performance, Designed to Stay Put
The Blackfin's full-rim bio-resin frame is flexible yet durable, and the Hydrolite co-injected lining is the secret to its no-slip grip. Hydrolite actually gets tackier when wet, so sweat and spray won't budge these frames. The wide temples provide side coverage that blocks peripheral light—a feature anglers appreciate when trying to see into the water. The integrated nose bridge and wraparound design offer maximum coverage and a secure fit for medium to large faces.
This frame is prescription-ready, so you can add your Rx and get the same performance optics tailored to your vision. The Blackfin comes with a hard case and is backed by Costa's limited lifetime warranty.
From the boat to the beach, the Costa Blackfin 9014 pushes the edge in sunglass performance—so you can push it everywhere else.

I am very satisifed with the sunglasses.
Costa makes the best glass lenses, and the Blackfin frame looks great. I like using the green lenses for outdoor activities like fishing, and they also function well when driving. Glad I ordered a pair of these, no regrets. I highly recommend getting a set of Costas from Designer Optics!
Nice glasses. Thought they were Glass lens not plastic. But still a fair price

Frequently Asked Questions
Are the Costa Blackfin 9014 sunglasses prescription-ready?
Yes, the Costa Blackfin 9014 is prescription-ready. You can have prescription lenses installed in this frame. Note that prescription limitations typically apply: combined SPH and CYL should not exceed +3.00 to -5.00, and CYL should not exceed -3.00 for this frame style.
What's the difference between Costa 580G and 580P lenses?
Costa 580G lenses are made of glass and offer the best optical clarity with scratch-resistant mirrors encapsulated between glass layers. They're 20% thinner and 22% lighter than typical polarized glass. Costa 580P lenses are made of polycarbonate, making them the most impact-resistant and lightweight option. Both filter yellow light at 580nm and provide 100% UV protection and polarization.
What size face do the Costa Blackfin sunglasses fit?
The Costa Blackfin features a large lens front designed to fit those with an average to large-sized head. The frame offers maximum coverage with a wraparound design that helps reduce light leak. Multiple reviewers note the Blackfin fits medium to large faces comfortably and provides excellent side coverage.
Do Costa Blackfin sunglasses stay in place during active use?
Yes, the Blackfin features Hydrolite co-injected lining that provides a no-slip grip, even when wet. The Hydrolite material actually gets tackier as you sweat, ensuring the sunglasses stay locked in place during fishing, boating, or other active outdoor activities. The flexible bio-resin frame also contributes to a secure, comfortable fit.
What makes the Costa Blackfin good for fishing?
The Blackfin is designed specifically for anglers. The wide temples act as side shields to block peripheral light, making it easier to see into the water. The 580 lens technology filters yellow light and enhances contrast, helping you spot fish in shallow water. The polarized lenses eliminate glare from the water's surface, and the no-slip Hydrolite grip keeps them secure on your face.
Are Costa Blackfin sunglasses worth the price?
Reviewers consistently praise the Blackfin's optical clarity, build quality, and all-day comfort. The 580 lens technology delivers superior color enhancement and glare reduction compared to standard polarized lenses. Many long-term users report their Blackfins lasting for years with proper care. The combination of performance features, prescription-ready capability, and Costa's warranty make them a solid investment for serious outdoor use.

Costa Blackfin 9014 vs. Other Costa Fishing Sunglasses
The Costa Blackfin 9014 sits at the heart of Costa's fishing sunglass lineup, but how does it compare to other popular models in our catalog?
Blackfin vs. Brine
Both the Blackfin and the Costa Brine 9017 offer full-rim construction, 580 lens technology, and prescription-ready frames at similar price points. The key difference is frame shape and coverage. The Blackfin's wide temples provide exceptional side light blocking—a feature anglers value when sight-fishing or reading water. The Brine offers a different aesthetic and may fit certain face shapes more comfortably. If maximum side coverage is your priority, the Blackfin has the edge.
Blackfin vs. Tuna Alley
The Costa Tuna Alley 9009 is another core fishing frame with large wraparound coverage. Both models offer similar lens options and performance features. The Tuna Alley has a more angular, aggressive look compared to the Blackfin's rounded design. The Tuna Alley Pro version includes front lens vents for additional airflow, while the standard Blackfin relies on its co-injected frame design for comfort. Choose the Blackfin if you prefer a classic, rounded shape with proven wide-temple coverage.
Blackfin vs. Fathom
If the Blackfin feels too large, consider the Costa Fathom 9058. The Fathom is Costa's smaller-fit alternative, designed for small to medium faces. It shares the same 580 lens technology, Hydrolite grip, and prescription-ready capability, but in a more compact package. The trade-off is less lens coverage and narrower temples, which means less peripheral light blocking. For medium to large faces or anglers who want maximum coverage, the Blackfin remains the better choice.
Why Choose the Blackfin?
The Blackfin has earned its place as one of Costa's most popular frames for good reason. The wide temple design blocks side light better than most competitors, the medium-to-large fit works for a broad range of faces, and the combination of 580 lens technology with Hydrolite grip delivers all-day performance. If you're serious about fishing or spend long hours on the water, the Blackfin's proven design and exceptional optics make it a smart investment.
