The actual mechanism might be something like that! Nearsightedness is often caused by the eyeball developing to be too long. It’s actually dramatically increased in some places in Asia, where 90% of schoolkids can be nearsighted. [1] There’s a lot of research pointing towards biological processes involving contrast (which is probably a decent proxy for focus) being involved in eye development, with maybe different visual stimuli (due to more time spent indoors) being a potential cause of the increased myopia rates because it doesn’t activate the specific mechanism in the right way.
