Why can my eyes smoothly follow an object in motion, but when there is no object to follow (like staring at a wall), my eyes skip focus from point to point?
We have evolved a specific tracking system for our eyes, [smooth pursuit](_URL_0_) for tracking moving objects. A component of smooth pursuit is feedback from the optical system to the brain, to allow it to predict the movement we are tracking. Without that feedback (that is to say, without the m…
The Short Answer
We have evolved a specific tracking system for our eyes, [smooth pursuit](_URL_0_) for tracking moving objects. A component of smooth pursuit is feedback from the optical system to the brain, to allow it to predict the movement we are tracking. Without that feedback (that is to say, without the moving object) most people cannot kick off smooth pursuit mode.
