When I bring the screen closer to my face, the area where I can detect the movement becomes larger. Far away from my face, I can see only a few spinning. If this area corresponds to my fovea, wouldn't I expect the opposite? Perhaps larger spinners can be detected father away from the fovea?

If you move too far, the movement becomes too hard to detect even by the fovea.
