Opera glasses

Mother of pearl opera glasses and leather case.

Opera glasses, also known as theater binoculars or Galilean binoculars, are compact, low-power optical magnification devices, usually used at performance events, whose name is derived from traditional use at lorgnettes of the 19th century.

The London Opera Glass Company was founded in 1913 and provides opera glasses in many of London's West End theatres.[1][2]
