Hyperopic defocus

Hyperopic defocus is the technical term used by research papers to describe the blur caused by having the image focused behind the retina. It would normally be resolved automatically by accommodation, but the lens is not strong enough to do so for objects closer than the near point, which moves outwards during a ciliary spasm.

Studies show that it is a stimulus which, over time, can cause axial elongation.
