Costa Del Mar Sunglasses – Lenses

by Steven Neely


See Clearly. Catch More Fish. Polarized lenses are essential for anyone who spends time outdoors – especially out on the water. But not all polarized sunglasses are created equal. Your eyes are one of the most important tools in your toolbox, and the right pair of polarized sunglass lenses can make or break your days out on the water. It’s important to have the best-polarized lens technology available to reduce eye strain, squinting and to provide comfort by eliminating reflective glare. The harsh sunlight can reflect massive amounts of glare from the surface of the water back towards your eyes. Blocking glare not only helps protect your eyes when you’re spending hours on the water, but it allows you to see through the surface of the water more clearly to gain a competitive edge when fishing. Costa Del Mar makes only polarized sunglasses with UVA and UVB protection. Because the brand Costa Sunglasses believes blocking reflective glare is essential for anyone on the water or outdoors, the Costa utilizes the best performance technology on the planet for fishermen.

Choosing A Lens Colour

Light conditions are constantly changing. To get the most out of Costa Lenses, it’s important to choose the right colour. We offer seven lens colours that range from low light, like dawn, to extremely bright light with blinding glare.

For offshore, a blue mirror is the way to go. For freshwater and inshore, green mirror and copper are great options. For low light at dawn or dusk, the sunrise silver mirror is perfect. Gray lenses are the best choice for everyday activities. Of course, the best way for you to decide is to consider your environment.

Our mirrors are more than an aesthetic, they put Costa on the map. Made through a high-tech beam ion deposition process, these multilayered thin film coatings make for the most scratch-resistant mirrors out there. By bouncing reflected light away from the eye, they deliver superior contrast and colour while enhancing visual acuity. Our mirrors are available in blue, green, sunrise silver, gray silver and copper silver.

  • Encapsulated mirrors (between layers of glass) are scratch-proof
  • 20% thinner and 22% lighter than average polarized glass


  • Polycarbonate & are your lightest and most durable lens material options
  • C-WALL® is a molecular bond which is scratch-resistant

What Are Mirrored Lenses? 

Mirrored sunglasses have a reflective coating on the outside of the lenses that look like small mirrors. A pair of mirrored sunglasses will decrease the amount of light that passes through the lens and have lower light transmission to block more sun, cut glare, and protect you more. The outside colour of the mirror is independent of the colour of the lenses that you look through, meaning the base colour of the lens can be different on the inside. For example, a blue mirrored lens can have a gray tint lens base, and a green mirrored lens can have a copper tint lens base.

Beyond Polarized

Most polarized sunglass lenses eliminate glare by blocking reflective light. But Costa Sunglasses’ patented 580 lens technology goes a step further by blocking the perfect amount of harsh yellow light and potentially harmful blue light while enhancing reds, blues and greens. Essentially, Costa 580 lens technology keeps the bad light out and lets the good light in. The result: less haze, less blur, greater contrast and greater clarity. The best lenses on the planet mean the best sunglasses on the planet. And with technology that goes beyond normal polarization, you’ll get polarized lens technology that is the best for fishing and best on the water for other performance water sports like surfing, boating, paddle boarding, and kayaking. Available in the clearest scratch-resistant glass lenses (Costa 580G) and available in lightweight, impact-resistant polycarbonate plastic lenses (Costa 580P), it’s like seeing in high definition. See better so you can fish better.

The lens’ multi-patented technology manages light by:

Absorbing Harmful High-Energy Blue Light (HEV)

  • 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

Enhancing Reds, Greens, and Blues

  • Blocking harsh yellow light at 580 nm on the visible light spectrum boosts the amounts of red, greens and blues naturally, enhancing colors and contrast

Filtering Out Harsh Yellow

  • For enhanced color, sharper contrast and higher definition
