Vintage glasses, 80s 90s, - Gem。Vintage Hudson glasses frames. Made in Korea, Z-87, 56 – 16, 140. Gold tone metal frames with red arms and red on the front of the frames. My grandfather owned an eyeglasses shop in the 1980s/1990s, and these were leftover from then. Most of what he had left were demo frames and likely never worn, but I’m not 100% sure on these as they don’t have demo lenses or any stickers/tags on them. They are in overall good condition, but there is some corrosion or something on the inside gold tone section of one arm, but the area isn’t. Otherwise, there aren’t any obvious issues and they still look great.
