Field of view or FOV is defined as the distance one can see from left to right in a binocular. FOV is measured in one of two ways linear and angular. Linear is the most common form of measuring FOV and is measured at 1000 yards. For example the Galileo C-735WA has an FOV of 500 feet, meaning that when you look through the binocular you can see 500 feet from left to right at 1000 yards. Alternatively the angular FOV is a measurement of a binoculars FOV in degrees.
