It sounds like nothing new to anyone who have ever noticed active focus happening after blink, but hey, now it’s scientifically proven Well, not active focus, because they did not measured visual acuity (with their setting it would be impossible I think), but rather eye movement. But I think it’s still relevant. I think there is a high chance that it’s the same trigger and maybe even same mechanism as what happens during AF.
Also they found some interesting visual cortex mechanism: when you move an object during blink, the eye moves accordingly, but the conscious mind does not acknowledge it. If you “simulate” blink and do the same movement, the conscious mind notices it.
Displacements of a visual target during eye blinks can go unnoticed
Eye movements nevertheless anticipate these unseen target displacements
Visual signals recalibrate eye gaze position across eye blinks
