I believe you're wrong about your belief. As a kid I already noticed that, when looking at a watch, there is a chance that the first second takes too long. And my vision always stays sharp during movement, no blurry tails around anything when moving the eyeballs. Even when "looking" for it and making wild eye movements. But I feel like things become a little bit more detailed (left from me is a window, so that might just be the pupils adjusting). That's not to say that you're lying about what you're seeing; but it is quite possible both perceptions are possible ;-)
