Range of view refers to the extent or area over which one can visually perceive or observe objects, scenery, or events. It relates to the comprehensive field of vision available to an individual or the viewing angle encompassed by a particular device or location.
In the context of human vision, the range of view represents the maximum horizontal and vertical angles that the eyes can detect objects or details without moving. It is determined by the capacity of the peripheral vision and the central vision. The range of view may vary among individuals, influenced by factors such as age, visual acuity, and eye health. Some people may have a wider range of view, allowing them to see objects or events occurring in a larger area, while others may have a narrower range of view, causing limitations in their field of vision.
When referring to devices or instruments, such as cameras, binoculars, or telescopes, the range of view represents the span of the scene or area that can be captured or observed. It is described in terms of the horizontal or vertical angles or the width/height of the field of view. A wider range of view allows for a larger portion of the surroundings to be captured or observed, while a narrower range of view limits the area being seen.
Overall, the range of view encompasses the spatial scope of visual perception, either in terms of human vision or the capabilities of viewing devices, to comprehend the extent and breadth of the visual field.
