Your view of vision is entirely inaccurate, because the way vision _actually works_ sounds very, very wrong or at least scientifically inaccurate. Your eyes are not cameras and you don’t actually see the light that hits them - your brain constructs its impression of the world, uses the light perceived by your eyes to error correct, and that’s your phenomenological sense of vision. Saccades are real - your brain blocks out input for microseconds and backfills what it thinks you would have seen, manipulating your sense of time, too. Your visual processing takes longer than your auditory processing; synchronous perception too is an illusion your brain pulls to show a coherent world (and is likely part of why optical illusions work - your brain is “projecting” where it thinks the world is a couple microseconds ahead so it matches what you’re hearing). Selective attention is a real thing - check the video someone linked above for a solid example. The peripheral blindness mentioned is real, and occurs for similar reasons to your blind spot (your actual blind spot, the spot in your retinas where your optic nerve passes through your optic dish and you have no photoreceptors, so your brain just.. makes up what should be there).
Vision is not a process by which your camera eyes capture an image and your brain reports it, it is a process where your brain makes a guess about the world and tries to truth check it with external stimuli. It is not a faithful process, and where it renders reality, it does so because it’s expected to be sufficiently advantageous for your survival to be worth the effort.
