Binoculars

Binoculars are the world's most common and most used optical tool. Everyone should own a good pair of binoculars and once you own one, the more uses you will find for it. Binoculars are the primary tool for a wide range of activities.

Binoculars, field glasses or binocular telescopes are a pair of 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 sizes vary widely from opera glasses to large pedestal mounted military models. Many different abbreviations are used for binoculars, including glasses, nocs, noculars, binos and bins.

Unlike a?á (monocular) telescope, binoculars give users a three-dimensional image: for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a merged view with an impression of depth.
