3 Vintage Eyeglasses (1 Pinch Frameless Eyeglasses) And 3 Eyeglass Cases

1st photo top eyeglass is free of cracks and chips and condition is good. nose bridge is a 12 karat gold. 1st photo second from top has some minor scratches on the left lens these are bifocals no other issues noted 1st photo bottom glasses appear to be the oldest but have no side temples. the hinged aluminum case holder does not close all the way as seen in the photo i am not sure that these are the original cases as this has been in our collection for over 45 years and do not recall any specifics.
