These KATE SPADE eyeglasses are made of sustainable eco-acetate for a positive vision of the future that's kind to the planet. The hinges are flexible, for optimal comfort. The silhouette? Versatile, and anything but boring. The lightweight frames come in the season’s hues, including a color gradient version. The SO HAPPY TO SEE YOU inscription appears on the inside of the temples, and the small metal logo brightens the look.
