These gorgeous vintage glasses were made by Swan Optical U.S.A. in the late 1970s/early 1980s. They are NOS (new old stock) and have never been used. We have installed new mauve fashion lenses, but they can accommodate the prescription or non-prescription lenses of your choice. The frames are pale pink, with some orange and violet marbling. With striking drop temples and classic 70s shape, they will make a groovy addition to your eyewear collection!
