Sunglasses for Sailing and Regattas: A Technical Guide
In a regatta you spend hours with the sun reflecting straight off the water, with no shade and no break. Regular sunglasses fall short: they don't filter that glare, they can't handle salt water or constant wind, and if they go overboard, they're gone for good. Here's what actually matters before buying sunglasses for sailing.
Why regular sunglasses can't handle a regatta
On board, the glare doesn't just come from the sun — it comes from the water's surface too, hour after hour, tiring your eyes faster than you'd think and making you miss real detail in the wind and water. Add salt, constant spray, and apparent wind, and any frame not built for this loosens up fast. And in a quick tack, sunglasses without a secure fit go overboard as easily as a cap.
What actually matters in sunglasses for sailing
1. Real UV protection, not just a dark lens
At sea, UV exposure is higher than on land because of the water's reflection — a simply dark lens doesn't protect you the way a lens with a certified UV400 filter does. That's the baseline before you look at anything else.
2. A mirrored REVO lens against glare off the water
A mirrored REVO lens cuts the reflected light bouncing off the surface and gives you back real contrast to read gusts, other boats, and buoys at a distance — exactly what you need on a long day out.
3. Keeping them from going overboard
In a tack or a strong gust, sunglasses without a secure fit fall off — and once they're in the water, you're not getting them back. That's why on long or windy sessions it's worth using a safety floating leash: if they fall, they float instead of sinking.
4. A frame that handles salt and sun without warping
Dried salt and repeated sun exposure warp a cheap frame after just a few outings. A flexible TR90 frame handles that constant use without losing its shape or fit.
Our athlete's choice: Zac Blomeley and the Falcon
Zac Blomeley, professional sailor and Olympic hopeful — captain of Team Oceana Vivo, aiming to qualify for the 2028 Olympics — sails certified in the Falcon: open field of view, REVO lens, and a TR90 frame built for water sports, compatible with the floating leash. In his own words: “Precision, control, and vision. With my Falcon, I'm always one step ahead.”
Other KOH models for hours on the water
The rest of the water sports sunglasses collection shares the same technical base that matters for sailing: UV400 protection, a hydrophobic lens, an adjustable TR90 frame, and anti-fog coating — the difference between models comes down to frame style, not whether they hold up on a long day out.
Frequently asked questions
Are polarized lenses better for sailing?
They're not "better," they solve different things. REVO manages light intensity and gives you real comfort and contrast sailing under strong sun — and the same lens works just as well for kitesurfing, windsurfing, or any other outdoor sport, without tying you to a single use. Polarization works differently: it specifically filters the glare bouncing off flat surfaces. At KOH, that combination lives in the MK Sapphire line, built for a different use. For sailing, REVO gives you the protection and visual comfort you need — and the same sunglasses go with you across the rest of your sports.
What sunglasses does Zac Blomeley wear?
For sailing, the Falcon — his certified model for water sports within the KOH athlete program. (He also wears the MK Sapphire, but that line isn't built for water sports.)
How do I avoid losing my sunglasses if they fall in the water?
With a safety floating leash — if they come loose, they float on the surface instead of sinking, so you can recover them before they drift away from the boat.
Do the same sunglasses work for light sailing and offshore regattas?
Yes, the technical demands are the same — glare off the water, salt, wind, and the risk of losing them overboard don't change based on the type of boat.
If you're spending hours of regatta racing under glare off the water, just any sunglasses won't cut it. Discover the Falcon that Zac Blomeley wears, or explore the rest of the water sports collection.
