ContributorCommunity HistoryDescriptionBrass and leather opera glasses/binoculars. Theatre binoculars or Galilean binoculars, are compact low power optical magnification devices, usually used at performance events. The name is derived from traditional use of binoculars at opera performances. Magnification power below 5x is usually desired in those circumstances, in order to minimize image shake and maintain a large enough field of view.
