There are a few characters in the franchise with only one Byakugan, such as Ao or (presumably) Boruto. I've recently been wondering what the difference in abilities is between a single Byakugan and a double Byakugan. For example, would you only be able to see a 180 degree field of vision with that Byakugan, or would you be able to see a nearly 360 degree field but with half the range? Has this ever been officially answered?
