Visual angle refers to the angle formed at the eye by the lines of sight to the edges of an object. It is a measure of how large an object appears to the observer, depending on its size and distance from the observer. The visual angle is usually expressed in degrees, minutes, or seconds. In practical terms, as the distance from the observer to the object decreases, the visual angle increases, making the object appear larger.
