I found research supporting what @what-if-i-just-did and @foone said. The University of Rochester's science communicator Lindsey Valich reported several recent studies on the topic, like on 2023-02-23:

Our eyes are never at rest. Instead, they remain in motion, even between our voluntary gaze shifts, through fixational eye movements—small, continuous movements of the eye that we are not aware of making…

In a paper published in Nature Communications…the research shows the visual system continually monitors motor activity, even when people believe they are maintaining a steady gaze.

She reported another on 2021-11-19:

Fixational eye movements are tiny movements of the eye—so small we humans aren’t even aware of them. Yet they play a large role in our ability to see letters, numbers, and objects at a distance.

In a new paper published in Proceedings of the National Academy of Sciences, researchers…[were] studying how a type of fixational eye movement called a microsaccade affects the foveola, a small region at the center of the retina…

The researchers focused on microsaccades, tiny rapid gaze shifts that frequently occur when we’re examining fine details. It’s long been known that vision is transiently impaired during larger gaze shifts, such as those we are aware of making, for instance looking back and forth between two computer screens. This phenomenon of transiently impaired vision is known as saccadic suppression. Until now, however, it was unknown whether a suppression also occurs during microsaccades…

“We observed that microsaccades are accompanied by brief periods of visual suppression during which we are essentially blind…This brief loss of vision likely occurs so that we do not see the image of the world shifting around whenever we move our eyes. By suppressing perception during saccades, our visual system is able to create a stable percept.”

“Human Time Perception And Its Illusions” (David Eagleman, 2008-08-08) reviews many time-related optical illusions:

Here is a do-it-yourself demonstration to set the stage: look at your own eyes in a mirror and move your point of focus back and forth so that you're looking at your right eye, then at your left eye, and back again…

[B]ut here's the mystery: you never see your own eyes move. What happens to the gaps in time while your eyes are moving? Why doesn't your brain care about the small absences of visual input?

Eagleman (2008) specifically describes potential explanations of the “stopped clock” second hand illusion @foone mentioned:

In recent years, several groups looked at time perception around eye movements more carefully. This began with an examination of the ‘stopped clock’ illusion: upon first glance, the second hand of a clock sometimes seems to be stopped in place momentarily before it continues to tick at a normal pace.

Yarrow et al (2001) proposed that the scene the eyes land upon fills the time gap retrospectively [7], such that the eye movement is an integral part of the sense of time. Morrone and her colleagues then discovered that duration judgments were compressed during saccades [8]: when subjects were asked to judge an interval between two flashes near in time to a saccade (by comparison to two more targets well after the saccade), durations were underestimated by about a factor of two (Figure 1a).

More recently, Terao et al (2008) suggested a possible explanation for the saccade results, showing more generally that stimuli with reduced visibility (as stimuli are during a saccade) lead to the same sort of duration compressions [9]. While the data are clear, the mechanisms are still a subject of debate [10].

An intriguing explanatory mechanism for visual subjective time distortion is neuronal repetition suppression:

When a stimulus is shown repeatedly, the first appearance is judged to have a longer duration than successive stimuli [19-22]. Similarly, an ‘oddball’ stimulus in a repeated series will also be judged to have lasted longer than others of equal physical duration…

[N]euronal firing rates in higher cortical areas quickly become suppressed after repeated presentations of a stimulus [26-28], an effect generally known as repetition suppression…We have previously speculated that…a suppressed neural response corresponds to a shorter perceived duration [19].

Note that the duration distortions also occur with higher-level predictability. For example, if the series 1-1-1-1-1 is presented, the first stimulus appears longer…critically, the same illusion also occurs for the sequence 1-2-3-4-5 [19], presumably because the successive stimuli are predictable, even while their low-level shapes differ. This finding indicates that the predictability of successive stimuli involves higher cortical areas than the primary visual cortex, and that repetition suppression may be a special case of prediction suppression.

So, something I learnt the other day. So, you know how dinosaurs supposedly can't see you if you stand still? Well that myth is based on real-life lizards/etc and how eyes in general work. So, once my dad starts infodumping, here comes some other cool information. We, humans, can in fact, also not see something unless it's moving. We fixed this by having our eyes constantly shake. And then our brain compensates for us, so we don't have to have shaky vision.

What if aliens don't have this? Like. What if they find out when one of us was looking at something in the distance, and they walk around this thing that's in front of them, and the alien is confused so they bob their head and oh, there's a thing there, but how did the human know that, and then we explain and they're like, horrified.

Humans are apex predators. They can hunt in packs. They can hunt in pairs. They can hunt on their own. They're persistance predators, which is unheard of. They get stronger when they're mad or scared. They have this thing called 'body language' which acts like a type of hivemind, even if they'll claim it isn't. And. They can see you. When you're not moving. They can still see you. If you ever find yourself in a fight against a human, for whatever reason? Run. Run as fast as you can. And hope, pray if you have a religion, that they won't follow.

Weirdcore pretty pls…

Slytherin boys room. One has dirty clothes on the floor and a cake up his luggage and the other,even tough blind,clothes neatly put on a chair. Papa Gaunt privileage = their own dorm.

that's hilarious. I've read this story, and yeah, people die, it's pretty fucked up, and there sure is a cymbal monkey that looks Like That. I don't know how they're gonna stretch this into a whole movie. I hope they don't ever explain WHY the cymbal monkey kills people, it just needs to be a totally pointless and creepy toy

have you all seen that movie poster thats like "People die, and that's fucked up. THE MONKEY"
