These are prescription lenses. They are left in to prevent the frames from losing their shape, but please be sure to replace the lenses before use. *The prescription strength is unknown and cannot be provided. Simple cleaning completed. Due to being a vintage item, there is some yellowing and scuffing on the end pieces due to aging. As these items are inspected by eye, there may be some oversights. Please be sure to check the condition in the photos. We have many other eyeglasses for sale, so please feel free to browse our profile.
