GUCCI sunglasses. They have prescription lenses installed, but the original non-prescription lenses are also included. I believe they are the gray lenses. Also included are brown non-prescription lenses of a similar style, but slightly different size. The prescription of the installed lenses is believed to be -5.50 for the left eye and -5.00 for the right eye, but this is not exact, so please use it as a reference. The sunglasses themselves are in good condition, but the case has some wear and tear from use and storage. Otherwise, I don't think there are any problems, but please check the images for details. The size is indicated as 51□16-140. *Due to the room's lighting being incandescent and my poor photography skills, the colors of the product may not be accurately represented. I apologize for any inconvenience.
