I bought these a few years ago at a little shop nearby. They're one of my favourites from my collection.
The case and the glasses themselves are unmarked, except for a sticker that is too worn to read. So, the age is based on my own searches for similarly shaped ones (ear hoopies, contoured nose bar, general shape, case style), which pointed me to something c1910-1920's. I'm always erring on conservative with dating unmarked things...
They're very delicate and wobbly, so unfortunately they're not very wearable anymore!
