The term visual field is sometimes used as a synonym to field of view, though they do not designate the same thing.
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 (threshold).
