Vintage Christian Dior Womens Sunglasses Twisting Frame JYIXQ made in Italy

I got these glasses as part of a larger collection of mostly 80s - 90s sunglasses from my late uncle. I don't know exactly how old they are, but seems like they might be from the 80s or 90s. If anyone can help me out please message me. Please let me know if you see anything in the photos that should be added to the description, this isn't my area of expertise so any help would be appreciated. The lenses have a lot of small scratches, but it seems like they are all shallow (see last photo). The glasses were in a big box of sunglasses for the past 12+ years and got scratched. I don't know if they need to be replaced completely or if it's possible to resurface them somehow. Priced accordingly and open to offers. It seems that in good condition these go for $200-300 online, asking $150 or best offer Feel free to message me with any additional questions. I've taken photos of all of the markings and sizes that I could find printed, but let me know if I missed anything.
