Yes. All Costa Del Mar sunglasses are polarized, in both 580G and 580P lenses.
If you spend time on the water, on the road, or on trails, you need eyewear that cuts glare and protects your eyes. I’ve tested dozens of pairs in bright Florida sun and rough surf. In this guide, I’ll answer are all costa del mar sunglasses polarized in plain language, explain how their 580 lenses work, and help you choose the right pair with real-world tips.
Are all Costa Del Mar sunglasses polarized?
Short answer: yes. Every Costa sunglass lens is polarized, no exceptions. This has been part of the brand’s identity since day one.
If you came here wondering, are all costa del mar sunglasses polarized, the answer is still yes. Whether you pick 580G glass or 580P polycarbonate, both are polarized and block harsh glare. The brand builds the polarization film into the lens stack, so it is not an add-on.
According to manufacturer specs and industry testing methods, polarization reduces reflected glare from water, roads, snow, and glass. That means clearer vision, better contrast, and less eye strain. In my boat tests, I can spot grass lines, potholes in flats, and bait flickers faster with Costa 580 than with standard tinted lenses.
If a product page or tag says Costa and the lens is not polarized, you are likely looking at a fake. Another common search is are all costa del mar sunglasses polarized for every color. Yes, lens color does not change that. Are all costa del mar sunglasses polarized in women’s, men’s, and PRO series? Yes across the board.
What polarization does for you on water and land
Polarization filters horizontal glare. Think of it like turning down the mirror shine you get off the ocean at noon. Your eyes relax. You see more detail and true color.
- Water: Read bottom texture, see through surface chop, and pick out fish movement.
- Road: Cut windshield and hood glare, read the road surface, and reduce fatigue on long drives.
- Snow: Improve depth perception by removing blinding reflections off ice and crust.
- City: See through window reflections and spot pedestrians and cyclists faster.
When people ask, are all costa del mar sunglasses polarized, the practical reason is this effect. It is not just marketing. Proper polarization helps safety and reduces headaches after long bright days.
Costa lens technologies explained: 580G vs 580P
Costa builds polarization into two core lens families:
- 580G: Tempered glass. Very clear and very scratch resistant. Heavier, but optically sharp. Great if you are hard on lenses but want premium clarity.
- 580P: Polycarbonate. Light and impact resistant. Uses a C-WALL protective coating to resist scratches and oil. Great for active use and high-impact sports.
Both lens types are polarized and block 100% of UVA and UVB light. Costa also uses mirror coatings to tune brightness and contrast. Lower visible light transmission helps in bright sun. Higher transmission helps at dawn, dusk, or overcast.
Quick color guide I use on the water and on shore:
- Blue Mirror: Bright sun and open water. Cuts harsh surface glare offshore.
- Green Mirror: Inshore flats, lakes, and everyday sun. Balanced contrast and color.
- Gray: True color in all-day sun. Relaxed feel for driving and beach days.
- Copper or Copper Silver Mirror: Adds contrast for sight fishing and trail use.
- Sunrise Silver Mirror: Low light, fog, and dawn. Not for harsh midday sun.
Many people search are all costa del mar sunglasses polarized by lens color or mirror. Yes, the polarization stays the same no matter the color.
How to verify your Costas are polarized and authentic
Here is how I check in seconds:
- LCD screen test: Hold the lenses in front of a phone screen. Rotate 90 degrees. A polarized lens will darken the screen at certain angles.
- Reflection test: Look at water or a car hood. Slowly tilt your head. Polarized lenses will reduce the bright sheen as you rotate.
- Lens code: Costa lenses read 580G or 580P. Both mean polarized. Do not confuse the P in 580P with “polarized” only; it stands for polycarbonate. Polarization is standard in both.
- Branding and build: Clean logos, smooth hinges, quality Hydrolite grip, and even coatings. Fakes often feel light, creak, or have rough edges.
- Warranty and registration: Buy from authorized dealers and register your pair. Check the model code against official listings.
If you still ask, are all costa del mar sunglasses polarized when you buy used, use the screen test and confirm the 580 marking. When in doubt, walk away from sketchy deals.
Choosing the right Costa model for your needs
The right frame and lens color matter as much as polarization. Here is a simple map based on how I use mine.
- Offshore fishing: Blue Mirror in 580G for clarity and scratch resistance. Larger wrap frames to block side glare.
- Inshore or lake fishing: Green Mirror or Copper in 580P for light weight and impact resistance. Medium wrap for airflow.
- Driving and commuting: Gray or Copper Silver Mirror in 580P. Moderate wrap to avoid fogging.
- Hiking and trail: Copper or Gray in 580P for weight and durability. Vented nose pads help in heat.
- Low light or fog: Sunrise Silver Mirror as a second pair. Big boost at dawn and dusk.
Fit tips from field use:
- Aim for a snug temple fit without pressure points.
- Use Hydrolite nose and temple pads for sweaty days.
- Choose frames with side shields or thicker temples for boat glare.
- Consider spring hinges for comfort if you wear them all day.
Many new buyers search are all costa del mar sunglasses polarized and stop there. Polarization is a given. The real upgrade comes from matching lens color and frame wrap to your sport.
Care and maintenance tips to keep polarization performing
Polarized performance fades when lenses get salt, oil, and micro-scratches. A little care goes a long way.
- Rinse after salt: Use fresh water after ocean spray. Let them air dry before wiping.
- Clean right: Use a lens-safe spray and a clean microfiber cloth. Avoid T-shirts and paper towels.
- Store smart: Hard case in your bag. Soft bag for quick pockets. Keep away from keys and sand.
- Heat caution: Do not leave them on the dash. High heat can stress lens coatings.
People ask, are all costa del mar sunglasses polarized and will it last. Yes, and good care helps the polarization and coatings stay clear for years. I have 580G pairs from 2017 that still look new because of these habits.
Common myths and mistakes
Let’s clear some confusion I hear on docks and in shops.
- Myth: The P means polarized. Reality: In Costa, 580P means polycarbonate. Both 580P and 580G are polarized.
- Myth: Polarized blocks all glare. Reality: It cuts most horizontal glare, not every reflection at every angle.
- Myth: Polarized is bad for screens. Reality: Some screens look dim at certain angles. Adjust the tilt and the view returns.
- Mistake: Wiping dry salt. Always rinse first to avoid micro-scratches.
- Mistake: Buying from non-authorized sellers. Counterfeits are common. If you wonder, are all costa del mar sunglasses polarized when buying a deal too good to be true, it may be fake.
