Field of view

The field of view (also field of vision, abbreviated FOV) is the extent of the observable world that is seen at any given moment. In case of optical instruments or sensors it is a solid angle through which a detector is sensitive to electromagnetic radiation.

Humans and animals

In the context of human vision, the term “field of view” is typically used in the sense of a restriction to what is visible by external apparatus, like spectacles or virtual reality goggles. Note that eye movements do not change the field of view.

If the analogy of the eye’s retina working as a sensor is drawn upon, the corresponding concept in human (and much of animal vision) is the visual field. It is defined as “the number of degrees of visual angle during stable fixation of the eyes”. Note that eye movements are excluded in the definition. Different animals have different visual fields, depending, among others, on the placement of the eyes. Humans have an almost 180-degree forward-facing horizontal diameter of their visual field, while some birds have a complete or nearly complete 360-degree visual field. The vertical range of the visual field in humans is typically around 135 degrees.
