Ref: field of vision.
Origin of visual field:
visual field, field of vision, field of regard(noun)
all of the points of the physical environment that can be perceived by a stable eye at a given moment
The term visual field is sometimes used as a synonym to field of view, though they do not designate the same thing. The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments", while 'field of view' "refers to the physical objects and light sources in the external world that impinge the retina". In other words, field of view is everything that causes light to fall onto the retina. This input is processed by the visual system, which computes the visual field as the output. The term is often used in optometry and ophthalmology, where a visual field test is used to determine whether the visual field is affected by diseases that cause local scotoma or a more extensive loss of vision or a reduction in sensitivity.
