The Ralph Lauren brand has been creating sophisticated and timeless styles since its inception in 1970. Ralph Lauren designs celebrate the refined luxury and understated elegance that is at the heart of American fashion. Ralph Lauren makes sunglasses that are attractive, elegant, and bold, and Ralph Lauren's distinctive luxury is reflected in every frame and lens. Ralph Lauren's contemporary styles and homage to vintage designs contribute to each frame's clean lines, subtle glamour, and uncomplicated class. Due to manufacturer's restrictions, Ralph Lauren products cannot be shipped to Australia.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.The sunglasses are available on certain colors with gradient tinted lenses - Gradient tints are tints that start off at a darker color at the top of a lens and then gradually lighten towards the bottom of the lenses. These tints are great for fashion and for reading outside on sunny days. Gradient coatings work by allowing an appropriate amount of light to filter through in certain areas and less in places where protection is most necessary.
