[[Hyperopic defocus]], excessive [[myopic defocus]], form deprivation, and [[accommodation]] strain can all cause [[axial elongation]]. In particular, using distances glasses for close-up is a very common cause of it. | [[Hyperopic defocus]], excessive [[myopic defocus]], form deprivation, and [[accommodation]] strain can all cause [[axial elongation]].

Hyperopes tend not to report back with any progress toward 20/20 vision. An implication is that EndMyopia techniques may not work for far-sighted people. This may indicate that we aren't changing axial length with EndMyopia techniques. Another theory is that EndMyopia might work by flattening the lens. It's easier to flatten a lens than to squeeze it, so this would explain why EndMyopia doesn't seem to attract people with hyperopic vision. Probably related, see also [[Dr. Carr]]. | |||
