Where does a farsighted eye focus an image?
2 Answers
A far sighted eye focuses the image in front of the retina.
Explanation:
A far sight eye is elongated or longer than a normal eye. The lens then focuses the light where a normal eye would be that is in front of the retina.
In a near sighted eye that eye is shorter than the normal eye. This has the effect of the light being theoretical behind the retina.
Farsighted eye can not properly see near objects: because light from near objects tend to meet beyond retina.

Explanation:
Farsighted condition is called hyperopia or hypermetropia. The problem could be due to slightly smaller size of eyeball in young children, which naturally gets corrected as the eyeball grows in size with age.
People nearing 40 or above may also suffer from farsightedness but they are not able to focus image of near objects on retina due to a more stiffened condition of lens (i.e. elasticity of lens is lost as we undergo ageing). The condition is called presbyopia, a problem that develops due to insufficient accommodation of lens with ageing.
The condition could be corrected by using converging lens.
