Neither staring at monitors nor print is actually expected to actually cause worsening eyesight. The idea that nerds need glasses because they stare at small print is a myth. On the other hand poking yourself in the eye and ignoring discomfort caused by the pressure could easily see you do some local damage. I would not advise anyone to actually follow your eye care regimen.

Close work may result in higher rates of nearsightedness, especially in children. Studies don’t all point in the same direction, but some definitely indicate this: https://www.theatlantic.com/magazine/archive/2022/10/kids-glasses-vision-increased-nearsightedness-myopia/671244/ https://www.theatlantic.com/magazine/archive/2022/10/kids-gl...

  But it tends to not be about the "closeness" AFIK. But about most "close work" being work which requires your eyes to focus on details, which in turn reduce the amount you blink, which in turn dries out your eyes which in turn can negatively affects it over a long time in various ways. In children there is also the additional factor that part of their organs are potentially still developing and various external factors might nudge such development in bad directions. Through idk if that applies here. Lastly some degree of sightedness is your brains ability to process the signals it gets, that part can sometimes, especially in children, make exact diagnosis surprisingly harder. You can sometimes observe this yourself if you have glasses, look with glasses at a text which without glasses you are barely not able to read. Then take of glasses and observe that while you initially are barely not able to read it after some time your brain tends to adapt and make it barely readable. So there is some chance that children brains might just have learned less to process far away signals, without their physical eye sight being change. Through I don't have time to find/read the study implicitly linked through the newspaper to check there methodology to check if it could have affected the study or if it couldn't have.

    > But it tends to not be about the "closeness" AFIK. I've seen studies explaining their findings as the muscles getting used to only focusing near, as a sort of range of motion thing. One study grouped kids based on the amount of time spent outdoors vs indoors (as a rough proxy of focusing on distant vs only on near things) and showed a statistical difference in myopia rates between the groups.

The real issue is being inside and not exposed to high intensity natural sunlight. That's how south Korea got 90% myopia in a single generation.
