Hyperopia, or farsightedness, is a disorder where distant objects are usually seen clearly, but close ones do not come into proper focus and are blurred.

 Astigmatism, Farsightedness, Nearsightedness, Presbyopia
In normal vision, light rays from an object entering the eye are focused by the lens (transparent tissue that changes shape to help focus incoming light) on the retina (the membrane at the back of the eye that transmits images of external objects to the optic nerve).
Farsightedness is present at birth and tends to run in families.
The condition usually is not severe in young children, and mild cases sometimes correct naturally-as these children grow, eye muscles adjust the distortion of the lens until light rays from near objects focus correctly on the retina, resulting in sharp vision.

Hyperopia, or farsightedness, occurs when images are formed behind the retina, resulting in a blurred image.
This is due to an eye that is relatively too short, or the refractive powers of the cornea and lens of the eye are relatively too weak.
Depending on the degree of farsightedness and the age of the individual, some farsighted people may see clearly at both distance and near through the process of accommodation, or focusing of the lens in the eye.
