Axial length of the eyeball is the distance from the lens to the retina. Elongation is the scientifically accurate reason why anyone has myopia.
Biology
It would require precision engineering to be able to grow an eye that was perfectly emmetropic at birth. Instead, it is of approximate dimensions, and feedback during postnatal development tunes the axial length to match the focusing system. [1]
How it can be reduced
Myopic defocus, as well as conscious accommodation of the ciliary muscle during active focus. Finally, good distance vision practices.
