VISUAL FIELD Meaning and
Definition
-
Visual field refers to the entirety of the area in the external world that an individual is able to perceive with their eyes when looking straight ahead, without moving their gaze. It encompasses everything that can be seen by both eyes simultaneously, including objects, shapes, colors, and motion.
The visual field is typically described as a two-dimensional space that extends horizontally and vertically, comprising the total range of vision available to an individual. It includes the central visual field, which refers to the area directly in front of the individual and within a fixed degree of fixation, and the peripheral visual field, which encompasses the outer edges of one's visual range.
The size and quality of an individual's visual field are influenced by several factors, including the health and functioning of the eyes, the optic nerve, and the brain's visual processing centers. Conditions such as glaucoma, retinal diseases, and brain injuries can result in visual field loss or impairment, characterized by the inability to see certain areas or a reduced perception of the visual environment.
Visual field testing is commonly performed by eye care professionals to assess the extent and quality of an individual's visual field. This evaluation is crucial for diagnosing and monitoring various eye conditions, evaluating the efficacy of treatments, and determining an individual's eligibility for activities such as driving or operating machinery.

Etymology of VISUAL FIELD
The word "visual" originates from the Late Latin term "visuālis", which means "sight" or "vision". This, in turn, is derived from the Latin "visus", meaning "sight" or "sense of sight". The word "field" comes from the Old English term "feld", which refers to an open piece of land or a plain. Therefore, the word "visual field" combines the concept of sight or vision with the notion of an extended area or space. In the context of ophthalmology and neuroscience, the term "visual field" specifically refers to the total area that an individual can perceive while fixed on a central point.
