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. Due to the vintage nature of the item, there are areas where the coating and paint have worn off. The nose pads and temple tips (ear pads) have been replaced with new ones. Please check the condition in the photos. We have many other eyeglasses for sale, so please feel free to browse our profile.
