There are currently two basic mechanisms believed to cause<unk> : form deprivation (also known as pattern deprivation) and optical defocus. Form deprivation occurs when the image quality on the retina is reduced; optical defocus occurs when light focus in front of or behind the retina. Numerous experiments with animals have shown that<unk>  can be artificially generated by inducing either of these conditions. In animal models wearing negative spectacle lenses, axial<unk>  has been shown to occur as the eye elongates to compensate for optical defocus. The exact mechanism of this image-controlled elongation of the eye is still unknown. It has been suggested that accommodative lag leads to blur (i.e. optical defocus) which in turn stimulates axial elongation and<unk> .
