binoculars definitions

WordNet (r) 3.0 (2005)

n
1: an optical instrument designed for simultaneous use by both eyes [syn: binoculars, field glasses, opera glasses]

Britannica Concise

Optical instrument for providing a magnified view of distant objects, consisting of two similar telescopes, one for each eye, mounted on a single frame. In most binoculars, each telescope has two prisms, which reinvert the inverted image provided by the eyepiece of each telescope. Light rays travel along a folded path inside the telescopes, so the instrument has a shorter overall length. The prisms also provide better depth perception at greater distances, by allowing the two objectives (object lenses) to be set farther apart than the eyepieces. Binocular eyepieces are often fitted to microscopes or other optical instruments.

Oxford Reference Dictionary

n.pl. an optical instrument with a lens for each eye, for viewing distant objects.

Collin's Cobuild Dictionary

Binoculars consist of two small telescopes joined together side by side, which you look through in order to look at things that are a long way away. N-PLURAL: also a pair of N
