When the forecast calls for bright, sunny skies, be sure to grab your Costa sunglasses with gray lenses. They are dark enough to reduce eye fatigue and increase eye comfort under intense light conditions but not so dark that they impair vision when clouds obscure the sun. Since they don't change the value of color, they enable the wearer to view scenes in their most natural state. For deep-water fishing, wear gray lenses for maximum glare reduction.
