Costa Del Mar Gannet GNT 120 Shiny Tortoise Fade Sunglasses

These sunglasses are available with polarized lenses on certain colors. Polarized lenses have a filter within the lens that blocks the wavelengths of light that cause glare. They can greatly enhance contrast and allow for greater depth of vision, especially in water. They are ideal for any situation where glare reduction is necessary, like driving or playing sports. For serious outdoor adventures, you need polarized sunglasses that will stand up to the elements.
