There’s a rare disease that turns peoples faces into demon faces called prosopometamorphopsia that can be partially relieved by observing things under different colored light.

One thing I find very interesting about how brains process reality is that there’s a disease that makes your eyes have blind spots. However people with that disease don’t see those blind spots because the brain fills the gaps with the information it knows to be there. So you could see a door closed just as it was when you last looked at it directly, but in the meantime someone opened the door and you’re still seeing the door closed until you look at it directly.

We all have blind spots because there’s a hole in the retina in the back of the eye for the optical nerve. The spots are located on the outer top side of our field of view and you can become aware of them with some visual tests online.

Another fun thing you can do is look at the sky (not the sun!) on a sunny day and start seeing your blood circulation and blind spot.

It sounds like Op is describing motion blindness.
I do not know how those people function.

The top commenter is correct. It’s why when you glance at a clock with a second hand, it can seem like it takes too long for it to move for the next second. It moved as you moved your eyes, and your brain didn’t make up the movement.
