Your optic systems (eyes plus visual processing bits of your brain) are so good at lying to the rest of your brain that you time travel all the time. You can see while your eye is sitting still, but when your eyes move (it's called a saccade) it's like a video feed with a pause button - you get the last image from before the movement, then the camera moves, then once everything is squared away the feed continues. If the new video frame is too far out of sync with the last frame your optic system kinda says "eh... it was probably moving" and just does it so the rest of your brain just gets the smooth fill-in-the-blank version.
To be fair we'd be seeing a blur anyways so if your brain didn't lie to you, you'd just see a useless blur half the time. It'd be like, okay so you're not blind now but now you just see a useless blur instead of nothing.
There's nothing here!
