Costa Del Mar Trades Polarized Sunglasses
The Costa Del Mar Trades are built for the kind of life that happens at the edge of the water. Wide wraparound coverage, a bold rectangular silhouette, and Costa's legendary 580G glass lens technology combine into a sunglass that looks sharp enough for everyday wear and performs hard enough for serious time on the water.
580G Glass Lens Technology
The "G" in 580G stands for glass, and it matters. Costa's 580G lenses are ground from optical-quality glass rather than polished plastic, delivering a level of clarity, scratch resistance, and color fidelity that polycarbonate lenses cannot match. The 580 spectrum refers to Costa's approach to light filtration: the lens blocks high-energy yellow light at 580nm, which is the range most responsible for visual noise on the water, while enhancing the reds, greens, and blues that define contrast and depth perception in bright coastal environments.
Every 580G lens is polarized to eliminate surface glare from water, sand, and pavement. Polarization is a structural property of the lens itself, not a coating, so it does not wear off over time.
Frame Construction and Fit
The Trades frame takes a wide, squared-off wrap shape that maximizes peripheral coverage without crossing into sport-goggle territory. The profile sits close to the face to block stray light from the top and sides, which is the configuration that performs best in high-glare conditions on open water, at the beach, or behind the wheel.
Costa builds its frames to be durable. The material resists impact, flexes without cracking, and holds its shape through repeated exposure to salt, sweat, and sunscreen. Nose pads and temple tips are designed to grip even when wet, so the fit stays secure whether you are rigging a line, carrying a board, or just spending the day outside.
Why Costa Del Mar
Costa Del Mar is an American sunglass brand founded with a single focus: optics for people who spend serious time on and around the water. Every lens the company makes is polarized. The 580G platform represents the top of Costa's lens lineup, prioritizing optical glass and long-term durability for buyers who want a sunglass that performs as well in five years as it does on day one.
The Trades are available at Island Water Sports in store and online in South Florida.

Frequently Asked Questions
- Are the Costa Del Mar Trades sunglasses polarized?
- Yes. All Costa Del Mar Trades sunglasses use polarized lenses. Polarization is built into the lens structure itself, not applied as a surface coating, so it does not degrade with use.
- What is the difference between Costa 580G and 580P lenses?
- 580G lenses are made from optical glass, which offers superior scratch resistance, clarity, and color accuracy compared to polycarbonate. 580P lenses use polycarbonate, which is lighter and more impact-resistant but less scratch-resistant than glass. The Trades in this listing use 580G glass lenses.
- Why are Costa Del Mar sunglasses so expensive?
- Costa Del Mar sunglasses are priced to reflect the use of optical-quality glass lenses (in 580G models), structural polarization that does not wear off, durable frame materials tested for salt and UV exposure, and the brand's focus on purpose-built water optics rather than fashion eyewear. The Trades 580G represent Costa's premium glass lens tier.
- What is Costa Del Mar's return policy?
- Return policy details are available on the Island Water Sports website or by contacting the store directly at 954-427-4929. Costa Del Mar also offers a manufacturer's warranty on defects in materials and workmanship.
- Are Costa Trades sunglasses good for fishing and watersports?
- Yes. The wide wraparound frame limits stray light from the periphery, and the 580G polarized glass lens eliminates surface glare from the water while boosting contrast. This combination is well-suited to fishing, surfing, paddling, and other activities in bright coastal environments.
- How do I care for Costa 580G glass lenses?
- Clean 580G glass lenses with a microfiber cloth and lens-safe solution. Avoid paper products and shirt fabric, which can leave fine scratches even on glass. Store the sunglasses in their protective case when not in use to prevent contact scratches and frame distortion.
- Where can I buy Costa Del Mar Trades sunglasses in South Florida?
