'''Axial elongation''' is an increase in the length of the eyeball. | '''Axial elongation''' is an increase in the [[axial length]] of the eyeball. In young, far-sighted people, this shifts them from [[hyperopia]] towards [[emmetropia]]. In adults, this results in a higher degree of myopia, which is exactly what we're trying to avoid! | ||
Axial elongation in a [[lens-induced myopia]] context is primarily caused by [[hyperopic defocus]], typically [[close-up]] activity while wearing glasses that are too powerful for the distance in question. | Axial elongation in a [[lens-induced myopia]] context is primarily caused by [[hyperopic defocus]], typically [[close-up]] activity while wearing glasses that are too powerful for the distance in question. | ||
It can also be induced by using a lot of [[accommodation]] for a large fraction of the time, excessive [[myopic defocus]] (don't reduce too much!), or form deprivation from things like diffusers. | |||
