Field of View is the size of your scene. It's usually specified in distance of the lateral size of your scene, though sometimes it's specified by angle in degrees. For example your retina image might have a field of view of 12 millimeters wide by 8 millimeters high. See this: http://www.nikon.com/products/sportoptics/how_to/guide/binoculars/basic/basic_08.htm
