> A few years ago I found a technique on youtube to help myopia by wearing slightly lower prescription glasses.
That is not physically possible.
Maybe (and that's a big concession, I'm very skeptical) it could work with kids, with still-developing eyes. No amount of glasses trickery will reshape your cornea in adulthood.
Other than the physical world constraints, if this hypothesis was true, people's myopia would never progress, as you would, by definition, be wearing lower prescription glasses if this happened, so it would self-correct.

The only thing this will get you is a headache.
