You're eyes do have a 'frame rate' as it were. That's why you can't see fluro strip lights flickering. They do it at such a frequency that your eyes don't notice. As others have mentioned, ever watched a car wheel while it's spinning? Or even a mtb tyre as you prin it in front of you? You will get the same effect as seen on a camera but at a different speed.
