Binoculars – (also known as field glasses) are two identical or mirror-symmetrical telescopes mounted side-by-side and aligned to point accurately in the same direction, allowing the viewer to use both eyes ( binocular vision) when viewing distant objects. Most are sized to be held using both hands, although there are much larger types. A binocular gives users a three-dimensional image: the two views, presented from slightly different viewpoints to each of the viewer’s eyes, produce a merged view with depth perception.
