visual field

This term is primarily used in clinical, ophthalmological, and neurological contexts to describe the spatial extent of vision. It refers to the total area visible to the eye from a fixed point, encompassing both the central focus and the peripheral vision.

In medical reports, a restricted or narrowed visual field is often described as "tunnel vision," whereas the loss of specific sections of the field is referred to as "scotoma." It is distinct from the "field of view," which is a more general term used in photography or optics to describe the extent of the observable world seen at any given moment.
