Opera glasses, also known as lorgnettes, are a type of eyewear that were popular in the 19th century. They consist of a handle and two lenses, and were used to magnify the stage during opera performances. The lenses were usually made of glass or crystal, and the handle was often decorated with jewels or other ornamental materials. Opera glasses were a fashionable accessory for wealthy theatergoers, and were often used as a status symbol.
