According to optometry science, eyeballs can become enlongated from front to back, or horizontally, which results in myopia (nearsightedness) or hyperopia (farsightedness).
If so, what exactly is it that changes the shape of the eyeball before the lens hardens or changes curvative? Even children have vision changes - so anyone or ODs know the answer?

The eyeball itself can change shape in any of four ways, namely:
-pressure changes of the vitreous fluid
-action of the musculature that connects to the eyeball
-growth of the orbital bones that exert pressure on the eyeball and change its shape
-pressure on the eye, usually from behind, by growths or masses (tumors)..

Genetics.
Faulty genes and modifications in genetic expression (how actively the information stored in a gene is transformed into a protein) is considered to be the leading cause of myopia and has an inheritance pattern which confirms a genetics etiology (cause).
