I have been looking at the market for several years, and I have only found this one and one other in Japan (the domestic price was 250,000 yen). Based on the shape, I suspect that it was used as a headache relief eyeglass. The spring plate in the bridge flexes flexibly, and this spring plate also provides stability by holding the nose and temples. I was told by the previous owner that it was made of white gold solid, and although I have not taken it to a jewelry store to confirm it myself, if it were white gold solid, it would be worth owning as a collection just for that, given the recent rise in gold prices.
