Depth of Field
... Depth of Field The distance range between the nearest and farthest objects that appear in acceptably sharp focus. Depth of field depends on the lens opening, the focal length of the lens, and the distance from the lens to the subject. ...

Refraction, Lenses, Aberrations
... A lens is a piece of glass (plastic) with two refracting surfaces, which are either curved (e.g., a segment of a sphere) or plain. Lenses are used to form images by refraction in optical instruments (microscopes, telescopes, cameras, etc.) ...
