I find this statement confusing, as field of view is angular. and an eight degree field of view is still an eight degree field of view, whether across a room or at the stars at (optical) infinity.

Can you explain your idea in a different way?

I believe you explained it exactly. Angle of view expressed in degrees, affects maximum FOV that is expressed in Feet/Meters at a 1000yards or 1000 meters. The angular expression affects the dimension of the actual field you see at different distances, which constantly increases the further away you are looking. On the other hand, the angle of view stays the same, regardless of the distance.

Think of it this way:

With respect to understanding angular view, and how it affects FOV at any given distance, envision yourself, holding your binocular and being the apex of a triangle, an apex angle being either wide or narrow.. Imagine, then, two angular lines extending outward from where you stand, that complete a triangle with a line that connects these sides while passing horizontally through the subject matter you are viewing. The width of that connecting line in front of you is the FOV at that subject distance. Its size depends not just on the angle at the apex, but on the size of the triangle that is formed. If the angle of the apex is wide, the FOV line, increases rapidly in width as you look at subjects further out, as you form a broader, larger triangle. But if the angle of the apex is narrow, the FOV increases less rapidly as you look out further. It becomes a larger but skinnier triangle. In either case, when you are closer to the apex, there isn't as much difference in the size of the line {FOV) in actual feet between the sides when the triangles are smaller. So a maximum FOV of 399 yards vs one of 330 yards, will only be 69 feet more at 1000 yards. It may be only a few feet different when looking 10 yards away.

All this means means is that we can best appreciate a wider FOV when viewing subjects further away from us, than we can with subjects that are close up. Angle of view, on the other hand, never changes with distance. By itself, without taking distance into account, angle of view doesn't tell the whole story, at least in a practical way. FOV which it affects is more important. Confusion comes when you try to equate angle of view with FOV.

I hope this now makes some sense.
