Fishing sunglasses don’t just shield your eyes from the sun. They also reduce the amount of glare on the water’s surface, enabling you to see what’s beneath it. That’s crucial not just for sight fishing to saltwater flats species like bonefish and permit, but also for seeing trout feeding on insects just beneath the water’s surface. You can see cruising schools of baitfish, spot rocks and downed trees that might hold fish, and discern whether a bottom is gravel or mud. All those little clues can add up, and the more intel you have, the better your chances of catching fish. But a good pair of fishing sunglasses should have more features than just quality lenses.
