Vintage Opera Glasses with Spectacle Frame and Olympic / Ray-Ban Charms

This item is a pair of vintage opera glasses designed to be worn like spectacles, featuring a unique combination with a neck cord adorned with decorative charms. The primary optical components consist of two black cylindrical lenses, each housed in a multi-part casing with knurled elements for what appears to be focus adjustment. These lens tubes are affixed to a flat, black metal bar that forms the bridge and upper frame of the 'spectacles.' Extending from this bar are two thin, black metal arms that curve to a right angle, suggesting they were designed to rest over the ears like conventional eyeglasses. The construction appears to be predominantly metal, painted or coated in black, with some brass or gold-toned accent pieces, particularly where the lenses attach to the frame and at the pivots for the temple arms. The overall finish has a worn appearance, with some scuffs, scratches, and loss of original coating, revealing the underlying metal in places, particularly on the temple arms and around the lens housings. There is also some oxidation or patina visible on the small gold-toned fittings. A black nylon or similar material cord is attached to the temple arms via small metal loops, seemingly designed to hang around the neck. This cord is decorated with two notable charms: one displaying the 'Ray-Ban' logo and the other featuring the iconic five-ring Olympic symbol. The presence of these charms suggests a potential association with promotional items or a specific event, possibly from the era of late 20th-century Olympics. The item appears to be from the mid to late 20th century, likely between the 1960s and 1980s, given the style and the apparent wear. The craftsmanship, while functional, shows signs of utilitarian manufacturing rather than high-end luxury, indicated by the visible wear and material choices. The unique 'spectacle' design, coupled with the decorative charms, sets this item apart from standard opera glasses.
