PERIPHERAL FIELD Meaning and
Definition
-
The term "peripheral field" refers to the outer part or edge of a person's visual field, which encompasses everything that can be seen without directly looking at it. It is the area that lies beyond the focus of attention, yet still contributes to a person's overall visual perception.
In the context of ophthalmology and optometry, the peripheral field often describes the part of a person's visual field that extends beyond their central vision. It includes all the visual information that is detected by the peripheral vision or the "side vision." This region is essential for detecting movement, changes in light, and objects or events happening outside of our direct line of sight.
Moreover, the peripheral field is crucial for situational awareness and environmental perception. It helps individuals maintain spatial orientation and respond to potential threats or stimuli in their surroundings. For example, when driving a car, the peripheral field allows drivers to be aware of other vehicles, pedestrians, and potential hazards at the sides and rear without needing to turn their heads constantly.
Understanding and studying the peripheral field is significant in various scientific disciplines, such as vision research, human-computer interaction, and sports psychology. Researchers investigate how peripheral vision can affect performance, attention, and awareness in different tasks and activities, ultimately contributing to a comprehensive understanding of human visual perception.

Etymology of PERIPHERAL FIELD
The word "peripheral" derives from the Greek word "periphereia", which is a combination of "peri" meaning "around" and "pherein" meaning "to carry or bear". In English, "peripheral" is used to describe something that is situated on the outer boundary or periphery of something else.
The word "field" has multiple origins. In this context, it derives from the Old English word "feld", which is related to the Gothic word "faïhu", the Old High German word "feld", and the Old Norse word "fold". These various forms of the word all refer to an open, flat area of land that is not wooded or cultivated.
When combined, "peripheral field" refers to the outer region or edge of a wider field of vision or scope.
