My optometrist was quite skeptical of that anyone can cure their myopia. Yet I’m doing exactly that with measured improvement.
Can’t make a football into a soccer ball without surgery.
What you're proposing is /theory/ with few actual studies, research, or practical applications beyond some few people 'trying' something new.
Again, you may be able to lessen the football shaping with various methods. But at the end of the day, the body wants it to be a football, and you want it to be a soccer ball. Guess which of those competitors wins?
