From tons of articles, medical advices, etc. that insist that "you don't develop myopia from reading, monitor work, video games, etc".

They not not say that it's "purely genetic", but that's the impression one gets, that all those lifestyle params don't play any role...

Wikipedia says it's "a mix of genetic and environmnetal factors", and includes all of the above factors I've mentioned. But I've read many times in the past decades articles insisting that those other things don't matter (and presenting it as the medical consensus)...

As an adult, it would certainly be an outstanding discovery if this did matter. Which is why I'm skeptical about these supposed glasses. Sounds like snake oil, quacks like snake oil.

For children, teenagers and young adults: maybe. It's all about the eye shape, and children's bodies are still in development.

Why not? It's not about being "still in development".

All of our organs (heart, liver, knees, joints, ears) can deteriorate in various ways if we don't take care of them or abuse them in certain ways as adults (e.g. ears and loud music, especially on headphones, can lead to reduced hearing). Heart, well, we can have the heart of a 80 year old at 40 if we have the wrong lifestyle.

So why not eyes as well?

(Not to mention myopia usually rises over time in adults that have it - and they change glass perscriptions etc.), so it's clearly something that develops in adulthood too. Not to mention other things related to the eyes and their plasticity etc., like presbyopia, that strike at ~ 40-45 or so.
