The Atlantis Multi Focal Sunglass is large lens modified cat eye style. This multi focal style has 100% UV protected lenses. The power you order is the reading portion at the bottom of the lens. This power lessens as it goes to the top. People that can adjust to multi focus lenses can save several hundred dollars on these. If you cannot adapt, we always accept returns.
