Theatre binoculars

Opera glasses, also known as theatre binoculars or Galilean binoculars, are compact, low-power optical magnifying devices typically used at performance events, whose name derives from the traditional use of binoculars at opera performances. Magnification power of less than 5× is usually desired in these circumstances to minimise image flicker and maintain a sufficiently large field of view. Normally, a magnification power of 3× is recommended. The design of many modern, ornamental opera glasses is based on the popular 19th century lorgnettes.

In addition to the more stereotypical binocular type, folding opera glasses were another common design. These were made mainly of metal and glass, with a faux leather coating for grip and colour. Although folding glasses have been around in one form or another since the 1890s, they were perhaps most popular in the mid-20th century, and many from this era are marked "Made in Japan" or, more rarely, "Made in Occupied Japan". The model can still be purchased new, although most common contemporary models are now almost entirely plastic.
