(Wikipedia excerpt (amended): …” A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple types consists of a single piece of transparent material, while a compound type consists of several simple types (elements), usually arranged along a common axis. Commonly made from materials such as glass or plastic and are ground, polished, or molded to the required shape

A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called “lenses”, such as microwave, electron, acoustic, or explosive types…

Lenses are used in various imaging devices such as telescopes, binoculars, and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia… The word lens comes from lēns, the Latin name of the lentil (a seed of a lentil plant), because a double-convex lens is lentil-shaped. The lentil also gives its name to a geometric figure…”)
