You are absolutely right, I tested in on myself over several years. I want to share my story so far. Since I got a prescription of -4 I was so mad that I didn't want to wear those glasses. Furthermore I really felt like they were too "strong" for me. So I kept wearing the previous one that was at -3. Since then my myopia never got worse. But I wanted to go further and try to reverse it in some way. I have read many studies, like the one you mentioned about the animals with glasses/contact lenses that after some time develops myopia. That is the real proof that "too strong" glasses causes myopia. But what does "too strong" mean? It actually means 2 cases: the glasses that are actually stronger that the one you need (like -4 if you have -3.75), or the glasses that are used when you don't need them (short distance). In both cases you are slowly increasing your myopia (like the animal study). So to stop the myopia you just need to use the "right" correction for the "right" time. For example at PC you don't need full correction (for low myopia you don't even need glasses at all), because full correction is only for driving and looking at infinite distance. So the first thing to do, if you work at PC, is to buy less strong glasses (even super cheap one you can find on Amazon). What less strong means? It depends on your myopia and your distance from the screen. But you can calculate it using a ruler that has the diopters written on it (just print it: https://endmyopia.org/wp-content/uploads/2014/08/myopia-rule...). For example I've -3.5 but at PC I wear -1.5 because my screen is 70cm far. As other mentioned already, the best correction you need to use is the one that blurs the text a little bit, where you are still able to read but is not crystal clear. You may notice that this gets even harder if you have different myopia per eye, because one eye may blur, but not the other or viceversa (I still don't know what happens here, if it's better to cover 1 eye or not, etc). Btw, if you combine: less strong glasses at PC, regular intervals looking way far, no glasses for reading/phone, you will surely stop the myopia, and maybe you even improve. After years I just improved from -4 to -3.25, but it's better than nothing (and I was not so constant)... I'd love to hear some other experiences here.
