The sunglasses are Bausch & Lomb brand {while the nearly matching clear glasses (in the 4th photo) are by American Optical and are listed on a different ad}.

Note the ornate engraved pattern on the metal.

Measuring from the hinge to the farthest end of ear hook, the temple length of the sunglasses is about 95 mm.

The nosepads are translucent pearly, look original, and are probably bakelite (see https://shadetreevintage.org/NosePads.html).

Stamped inside the nose bridge pieces is B&L, 1/10 12 KGF, a 'P' with a square around it.

The ear hook coverings are pretty intact.
