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. They are clean with no noticeable scratches or stains. Since they are inspected by human eyes, there may be oversights. Please be sure to check the condition in the photos. We have many other eyeglasses for sale, so please take a look at our profile if you'd like.
