Are All Costa Sunglasses Polarized? Complete Guide

When it comes to premium eyewear for outdoor activities, Costa sunglasses are a top choice among anglers, boaters, and outdoor enthusiasts. One of the most common questions prospective buyers ask is: Are all Costa sunglasses polarized? The answer is clear yes, all Costa sunglasses are 100% polarized, providing superior glare reduction, full UV protection from the sun’s harmful rays, and ultimate clarity in a variety of light conditions.

Polarized lenses work by filtering out reflected glare from surfaces such as water, pavement, and snow, which can distort vision and lead to eye strain. Costa’s unwavering commitment to polarization means every pair they produce, whether it’s intended for fishing, driving, or everyday wear, delivers maximum protection without sacrificing visual quality. In this guide, we’ll explore Costa’s advanced polarized lens technology, explain what sets it apart from other brands, review the different lens options available, and help you choose the perfect pair for your needs.

What Are Polarized Sunglasses and How Do They Work?

Polarized sunglasses use a special filter to block horizontal light waves, which are the main cause of reflected glare. This type of glare can be distracting and even dangerous when driving or navigating bright, reflective environments. By filtering out these waves, polarized lenses help you see with higher contrast and more accurate colors.

Costa polarized lenses also offer 100% UV protection, safeguarding your eyes from harmful UVA and UVB rays. This is critical for outdoor enthusiasts who spend extended periods under the sun. The brand’s lens technology is specifically engineered to deliver superior performance in extremely bright light, making them a popular choice for fishing, boating, and other water-based activities.

Are All Costa Sunglasses Polarized?

Yes, all Costa sunglasses are polarized, regardless of the lens color, material, or frame style you choose. Unlike some eyewear brands that offer both polarized and non-polarized options, Costa Del Mar is fully committed to polarization as a standard feature across its entire lineup.

This decision stems from Costa’s roots in designing eyewear for anglers and outdoor professionals, who require ultimate clarity and glare reduction to perform effectively. The brand believes that every customer, whether they’re casting lines inshore, hiking through constantly changing light conditions, or driving on sun-soaked highways, deserves the benefits of polarization.

Key benefits of Costa polarized lenses include:

• 100% UV protection against the sun’s harmful rays.
• Glare reduction for improved visibility in bright or reflective environments.
• Enhanced color and contrast for a more vivid view.
• Reduced eye strain, allowing for longer periods outdoors without discomfort.

Because polarization is a core part of Costa’s design philosophy, you can be confident that any authentic pair of Costa sunglasses will kill reflected glare and provide the protection your eyes need.

What Makes Costa Polarized Lenses Different?

Costa’s polarized lenses stand out because of their proprietary 580 lens technology, which filters out specific parts of the light spectrum that cause visual discomfort. These lenses block harsh yellow light and HEV (high-energy visible) blue light, which can wash out colors and contribute to eye strain. By eliminating these unwanted wavelengths, Costa lenses enhance colors naturally and increase definition, giving you sharper contrast than average polarized glass lenses.

Lens Materials: Glass, Polycarbonate, and Trivex

Costa offers their lenses in three different materials, each with its unique advantages:

• Glass Lenses: Provide the highest level of optical clarity and scratch resistance. Ideal for those who prioritize ultimate clarity and durability.
• Polycarbonate Lenses: Lightweight and impact-resistant, making them a good choice for active lifestyles.
• Trivex Lenses: Offer a balance between clarity and impact resistance, lighter than glass but more durable than standard plastic lenses.

No matter which lens material you choose, polarization is always included.

Costa Lens Colors and Best Uses

Costa polarized lenses come in several colors and mirror finishes, each designed to optimize vision in different lighting conditions. Choosing the right lens color is just as important as picking the right frame style, especially if you use your sunglasses for specific activities.

Popular Costa lens colors include:

• Blue Mirror: Perfect for open-water and offshore fishing in bright light.
• Green Mirror: Versatile option for inshore fishing and sight fishing where light conditions vary.
• Copper or Copper-Silver Mirror: Great for driving and dawn-to-dusk use thanks to enhanced contrast in low light.
• Gray: All-purpose lens color that provides natural contrast and is comfortable in full sun.

By selecting the appropriate lens color, you can maximize clarity and contrast based on the environments where you’ll use your Costa sunglasses most often.

Are Polarized Prescription Costa Sunglasses Available?

Yes, Costa also offers polarized prescription sunglasses. This means you can get the same 100% polarized protection and clarity tailored to your vision correction needs. Prescription options are available in all lens colors and materials, allowing you to build a pair that matches your lifestyle.

Costa’s prescription lenses incorporate the same 580 technology, ensuring you don’t sacrifice clarity or glare reduction for vision correction. If you already own Costa frames, you may also be able to order replacement prescription lenses, making the process cost-effective and convenient.

How to Tell If Your Sunglasses Are Polarized

Because Costa sunglasses are all polarized, any authentic pair you purchase will feature this technology. However, if you want to confirm polarization, there are a few ways to test:

1. Look for the Etching: Costa polarized lenses are marked with “580” or “580P” for polycarbonate or “580G” for glass lenses.
2. Screen Test: Hold the sunglasses in front of a reflective screen or LCD monitor. Rotate them slowly; polarized lenses will cause the screen’s brightness to change or darken at certain angles.
3. Reflective Surface Test: When looking at water or another reflective surface, polarized lenses will reduce glare dramatically compared to non-polarized glasses.

These tests will give you confidence that you’re getting the maximum protection and glare reduction that Costa is known for.

Care and Maintenance Tips

Polarized lenses require special care to maintain their clarity and scratch resistance. Here’s how you can keep your Costa sunglasses in great condition:

• Clean Properly: Use a microfiber cloth and lens-safe cleaner. Avoid paper towels or harsh chemicals.
• Store Safely: Keep your sunglasses in a protective case when not in use to prevent scratches.
• Avoid Extreme Conditions: Prolonged exposure to high heat can damage lens coatings.

Costa lenses also feature a C-Wall coating, which repels water and oil, making them easier to clean and more resistant to scratches.
