The human eye does that naturally, and there’s not a lot you can do about it. …well, unless you have neurological damage. Then you might be able to stare straight ahead regardless of movement, but I don’t think it’s worth the tradeoff… For example: stand up, and stare straight ahead. Try to focus on nothing in particular. Easy, right? Now spin around in a circle. Your eyes will lock on repeatedly to things as they sweep past your field of view. It’s hardwired into your optical systems. This used to drive me nuts (for some reason) as a kid — I even tried to train myself to STOP focusing on things as they moved past & only stare straight ahead, but I just couldn’t overcome the hardwiring. No, really. I spent hours trying.
