Vintage Cazal Frames

Lenses have a prescription. These are for the frames! Vintage approx 1980. Authentic. There are no visible stamps inside arms- don’t know if worn off or weren’t there with early styles. Frames have gold and red and silver. Some mild wear to red on arms. Only imprint I can find is inside center of brow- “57/15”. Great edgy frames! Will come in a case but maybe not one pictured.
