What are the Causes of Hyperopia?
Hyperopia is caused if a personís eyeball is too short or when the cornea is too flat when compared to the normal eye.
In a normal eye, the light enters the eye through the transparent anterior part called the cornea. It then passes through the lens and gets focused on a point in the retina (the innermost lining of the retina that is light sensitive). Signals are then carried through the optic nerve to the brain, where vision is perceived.
Causes of farsightedness
- Farsightedness may be caused if the eyeball is too short or the cornea has too little curvature. It is often present from birth.
- Family history also contributes to long-sightedness.
Thus in hyperopia, the image from close objects is formed behind the retina rather than on it. This results in blurring of vision while trying to focus on close objects.
