Antique Shuron Round Lense Silvertone Reading Glasses Wire Frame Early 1900s

Based on my research, I date these glasses to the early 1900s But I''m not an expert by any means of the word. Due to the straight temple, where the lens sits (close to the eye), nose pads are there but brittle, shape of lenses is round, etc. I cannot tell what type of metal. They are Silvertone. Maybe they are children''s glasses (??) Totally unsure?? They are marked Shuron. Please see all pics and measurements.
