What Our Gearhead(R) Experts Are Saying:"I fished a full day on open water with the Heron Ocean Sunglasses and the difference the leather side shields make is real. The polarized lens killed the glare completely and I could actually see into the water, and at 25 grams they never once became a distraction through a long day on the boat."Out on open water, glare is relentless and unforgiving, and the Vallon Heron Ocean Sunglasses were built to handle exactly that. The Cat. 3 polarized polycarbonate lens cuts through reflected light off the surface with 100% UV400 protection, letting you read the water clearly whether you are scanning for fish, tracking a sail line, or navigating a kayak through chop. An anti-fog coating keeps vision sharp when conditions shift, and select colorways add a mirror coating for the brightest days on the water. Genuine leather side shields eliminate the peripheral glare and wind exposure that standard sunglasses leave unaddressed, wrapping the eye area completely for full protection from every angle. The TR90 Grilamid frame comes in at just 25 grams with fully adjustable stay-on temples that hold their position through active days on the water without needing constant adjustment. The detachable centrepiece and side shields let you configure the setup to match the conditions, and every pair supports one kilogram of plastic cleanup from the very environment you are out there exploring.
