What to Look for in Lens Colors for Flats Fishing

When selecting a lens color for your flats fishing sunglasses, there are a few main factors to consider. Let's review the criteria required by our Sports Opticians when curating the best polarized lens colors for fishing the flats.


No matter where you fish, polarization is a must. Anglers and opticians alike boast the game-changing effects of polarization when out on the water. It reduces glare, increases clarity, and allows you to see through the surface of the water more clearly.

Since flats fishing focuses your attention on the surface of the water, it's crucial to have contrast-enhancing lenses that help to separate colors and make details like moving fish 'pop'. All of the lenses in today's lineup feature contrast-enhancing lens technology or specific lens color bases to boost contrast.

Hydrophobic Coating

Don't let water droplets on your lenses block your view of that suspicious ripple. Hydrophobic coatings can make the world of difference for keeping your lenses crystal clear. These coatings repel water and sweat, so your vision remains unobstructed.

Best Polarized Lens Colors for Flats Fishing

Let's reel in the lenses!

Costa Green Mirror

It comes as no surprise that we've got a Costa lens to kick off our lineup. A fishing favorite, the Costa Green Mirror is one of the most popular lenses for anglers. A copper base creates a warm amber wash of color that boosts contrast in a variety of lighting conditions. On overcast days, the copper base excels at making details pop and for bright days, the green mirror delivers the sun protection you need. With a 10% visible light transmission, these lenses provide excellent coverage and, like all Costa 580 lenses, 100% UV protection.

Maui Jim HCL Bronze

Island-based Maui Jim only offers polarized lenses because they believe it's crucial to getting the best view and experience of nature. And for fishing the flats, we couldn't agree more.

The HCL Bronze lens is part of their patented PolarizedPlus2® lens technology. The HCL stands for a "High Contrast Lens," and the bronze color provides a warming effect that enhances color and contrast. Another standout feature of this unique lens is the bi-gradient mirror. The top and bottom of the lens have a subtle mirror to mimic how your eyes work when squinting. The HCL Bronze lenses do the work for you, so you get the extra glare reduction and protection needed to stay squint-free.
