What is the difference between the Field of View (FOV) and Apparent Field of View (AFOV)?

Field of view (FOV) is the degree of the angle of the visible field seen through binoculars. Although the FOV specifications may seem limited, it’s the apparent field of view (AFOV) that will dictate view perception, giving you a larger viewable angle. For example, a binocular with a field of view of 7 degrees may appear to have an apparent field of view of 50 degrees when you see the magnified image.
