That’s utter nonsense. I could post many many videos of my cats focused on objects on my latop or tablet screen or perhaps a session where they follow a bug around from a few cm away for fun. But i don’t need to since you can google many such examples. There’s even tablet games for cats since they can see things so clearly

Cats can’t focus on objects closer than about 25 to 30 cm away. https://youtu.be/mdqBbvYX3MU?si=MWZgpLbW-9NSsIcw https://youtu.be/mdqBbvYX3MU?si=MWZgpLbW-9NSsIcw https://www.petmd.com/cat/general-health/cat-vision https://www.petmd.com/cat/general-health/cat-vision

Just because they react to these objects doesn't mean they can see them clearly. It's just physics based on the eye and lens dimensions. With human eyes that threshold is about 10 cm, and if you try seeing objects closer than that you can still very much track and identify them, but they are blurry nonetheless. Maybe cat brains are also better at compensating for it, that part we can't really know, but they are most adapted to be ambush predators that don't really need to see things up close once they lock on and pounce.

  It doesn't even pass the smell test. A bit like "dogs can't look up" which is ridiculous to anyone with a dog. Eg. https://imgur.com/a/GwwzIEh https://imgur.com/a/GwwzIEh for my cat playing with tiny objects on the screen. Take this behaviour 100x over each day and you'll wonder how anyone can think they can't see things up close.

    Not being able to focus clearly on something != Not being able to see something completely. Maybe my wording was a bit off there. They see something there, it's just very blurry to them. It's measurable directly from lens and eye dimensions, and from pupil reactions, the way opticians measure people for their prescription. I know you're arguing in bad faith at this point, but just do an experiment, put your face 5cm close to a monitor, wave the mouse around. That's what your cat sees at 15cm away.
