A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired 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 lenses, electron lenses, acoustic lenses, or explosive lenses.

Optometry is a health care profession that involves examining the eyes and applicable visual systems for defects or abnormalities as well as the correction of refractive error with glasses or contact lenses and treatment of eye diseases. Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles. Modern-day optometry, however, has evolved through time so that the educational curriculum additionally includes significant training in the diagnosis and management of ocular disease, in most of the countries of the world, where the profession is established and regulated. Optometrists (also known as doctors of optometry in the United States and Canada, by a higher degree in the United Kingdom and worldwide for those holding the O.D. degree) are health care professionals who usually provide primary eye care through comprehensive eye examinations. They diagnose and manage various vision abnormalities including refractive errors as well as various eye diseases.
