Does our brain process the image our eyes see all at once, or does it start at one point and move from there (like starting in the centre and moving outwards, or from one side to the other)?

Idk if this is something that we have the technology to test, but I just wonder if this is a known thing or are there some working theories or something?

Also, knowing this could be used for things like marketing and creating illusions, right?

Primary processing of different areas of a visual field will happen simultaneously, as the cells doing the processing are actually topographically organized. However, because there is greater detail in the fovea (dead center) of your visual field, there's simply going to be more raw information to speed up downstream feature extraction.  This is pretty intuitive, as if we see a big brown fuzzy object somewhere in our visual field, we will recognize we are looking at a bear much quicker if we are staring at it than we would if it were on the periphery of our vision.
