Binoculars

Binoculars or field glasses are two telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes when viewing distant objects. Most are sized to be held using both hands.
Unlike a (monocular) telescope, binoculars give users a three-dimensional (3D) 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.
