They provide optimal visibility for indoor and outdoor use, weather conditions, and other situations. They are also recommended for nighttime wear. Polarized lenses: These lenses eliminate diffused light reflections and allow only natural light to pass through, providing clear vision. They also reduce glare from the ocean, rivers, and grass, as well as from harsh concrete and the glass of cars and buildings. They're recommended for outdoor sports like fishing, golf, driving, and skiing.
