Around the 1960s Vintage [American Optical] glasses. The worlds oldest eyeglass maker, commonly known as AO, is the worlds oldest eyeglass maker. Today, fashion frames are not produced and are very popular. Safety glasses used in factories at that time are fashionable Wellington type and easy to wear, and this is a more utility item because there is no windshield to make goggles and there is no installation. After being produced until around the 1980s, another company bought the mold and made it, so nowadays, the one of this age is a rare one. It features a grayish clear frame that is familiar to the face and has a feeling of intimidation. We have newly added clear UV lenses that have been maintained at the eyeglass store. The size of the wire (nawate) can be adjusted. (At your local optician) I dont know if you wear it, but when you hold it over the sun, you can see the color change of the frame. Also, this is also difficult to understand when wearing, but under the same conditions, cracks can be seen inside the base of the left temple. Please check the photo. We have scrutinized the condition, but since it is a vintage item, there are threads and scratches. Please purchase after understanding the characteristics of vintage and antique.
