What does stereoscopic mean?
Stereoscopic is an adjective describing something that uses two slightly different views or images to create the impression of three-dimensional space. A stereoscopic photograph presents a separate image to each eye, and the visual system combines their differences into a single scene with depth. The term can also refer to the binocular perception of depth and to display systems designed to reproduce that effect. It is especially associated with optical devices, photography, film, and modern three-dimensional screens, though the underlying principle is older than digital imagery. Because it names a practical way of turning flat pictures into an illusion of solid form, stereoscopic also carries a subtle cultural association with Victorian viewing devices and early demonstrations of photographic depth. In contemporary usage, the adjective is mostly technical but remains readily understood whenever an image or display claims to convey realistic depth.

Where does stereoscopic come from?
Stereoscopic was formed from stereoscope with the suffix -ic. Its terminology comes through the nineteenth-century English word stereoscope, which was built from Greek stereos, meaning “solid,” and skopein, meaning “to look at” or “examine.” The same Greek and Latin-derived vocabulary underlies cognates such as stereoscopy and stereoscopist, while stereogram belongs to the broader family of words associated with stereo.
