Mario Prada began selling leather handbags, shoes, travel trunks, and waterproof garments in 1913. In 1979, Mario's granddaughter, Miuccia, assumed the business and expanded the company into the luxury segment. The Prada sunglasses collection is distinctive, not only for its high quality standards, but for its forward-thinking approach to style. If you're looking for a non-conventional interpretation of fashion that embraces technology while respecting tradition, then look no further than Prada's distinctive line of sunglasses. Due to manufacturer's restrictions, Prada products cannot be shipped to Australia.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.
