Frequently Asked Questions

• What is Costa’s 580 Lens Technology and why does it matter for water sports?

  580 Lens Technology is Costa’s polarizing system that delivers about 99.99% polarizing efficiency, filters HEV blue light and harsh yellow light, and enhances reds, greens and blues for improved contrast and color definition on the water. That combination reduces glare and helps you spot structure, baitfish, and changes in water texture more easily.
• How do Costa frame materials and construction hold up in saltwater and active use?

  Costa frames use TR-90 nylon fused with Hydrolite to resist slipping and maintain optical alignment when wet, while stainless-steel hardware and hinge options (integral hinge, optical spring, and 5-barrel optical hinge) minimize corrosion. Many models also include vents and rubber nose pads or temple guards for a secure, breathable fit during active water sports.
• How do Lightwave glass lenses compare to polycarbonate or Trivex lenses in Costa sunglasses?

  Lightwave glass offers superior optical clarity and scratch resistance, ideal if maximum visual fidelity is your priority, though it is typically heavier than polymer options. Polycarbonate and Trivex lenses are lighter and more impact resistant for high-movement activities; all three lens types are available with Costa’s 580 treatment for glare reduction.
• Which Costa lens colors and models are best for different fishing or boating conditions?

  Choose from Costa’s seven lens color options based on light: the Dawn tint is tailored for low-light dawn/dusk conditions, while the darkest-tint/bright-condition options are meant for intense sun and open-ocean glare. Pair lens choice with a frame suited to your activity—lightweight models like the Ballast (about 16 grams) for long-duration wear or larger-wrap frames for maximum coverage in rough seas.
• What fit and security features should I look for when buying Costa sunglasses for watersports?

  Look for Hydrolite-infused TR-90 frames, rubber nose pads and temple grips, and vented frame designs to prevent fogging and slipping during activity. Also consider hinge type—optical spring or 5-barrel hinges add durability and alignment for heavy use—plus lightweight models if you wear sunglasses all day on the water.
