Binoculars typically come in either standard or wide angle designs. Wide angle designs provide a wider field of view than standard designs. Field of view is simply the area which you can see at a certain distance. The image viewed is usually measured in the number of feet you can see across at a distance of 1000 yards. A binocular showing a field of view of 430' at 1000 yds. means you can see a horizontal distance of 430 feet when looking out to a distance of 1000 yards.
