Sunglasses are an essential piece of gear in the subtropical sun. Polarized sunglasses cut the glare from the sun reflecting on the waves, and help you spot fish and manatees below the surface of the water. Polarized lenses make it hard to read digital displays, though - so if you're focused on your fish finder, choose a pair of non-polarized sunglasses. Whether you're going out fishing, diving, or just sunning yourself on the beach, take a pair of sunglasses. You'll be sad if you don't.
