When did Zingraff Paris opera glasses become popular?

Zingraff Paris opera glasses rose in popularity during the second half of the 19th century, especially between the 1860s and 1900. This period saw a strong interest in theatre and opera across Europe, with Paris acting as a cultural centre. The opening of grand venues such as the Palais Garnier in 1875 increased demand for accessories linked with theatre attendance. Opera glasses became a standard item among middle and upper classes, and makers such as Zingraff supplied pieces that matched current fashion. Records from the 1880s show that opera glasses were sold in department stores and specialist shops, with prices ranging from 10 to 50 French francs. That range placed them within reach of many urban households. By the early 20th century, production methods improved, allowing for more consistent quality. Zingraff examples from around 1890 often feature engraved metalwork and refined lenses. Popularity began to fade after the 1920s as cinema grew and social habits shifted.
