The farsightedness or hyperopia occur when light focused behind the retina. The main reason of this type of abnormality is that because of the lens and cornea may not be able to bend the light rays to focus them on the retina. Hence the light rays focused behind the retina.

Due to this small size of the eyeball the light rays focused behind the retina.
