Contrary
to other eye problems hyperopia or farsightedness starts at early ages. Farsightedness, also known as hyperopia, is a common type of
refractive error where distant objects may be seen more clearly than objects
that are near. However, people experience farsightedness differently. Some people may not notice any
problems with their vision, especially when they are young. It can be caused due to many reasons, but
heredity is the most common cause. It occurs when light
entering the eye is focused behind the retina
instead of directly on it.
This is caused by an eye that is too short, whose cornea is not curved enough, or whose lens sits
farther back in the eye than normal. In this, the far away objects appear clear
and the nearby objects appear blurry.
Some people might confuse hyperopia with presbyopia but presbyopia develops over time while farsighted vision is often hereditary.
Presbyopia is the result of the aging process, when the lens inside the eye gradually loses its flexibility, making it harder to focus on objects up close. It is noticeable around the age of 40.
Whereas in hyperopia, the eyeball of a person is shorter than normal which leads to blurry vision when light rays entering the eye focus behind the retina rather than directly on it. People with hyperopia or farsighted vision have to work overtime to keep things in focus.
Symptoms
of farsightedness can include:
- Blurred vision, especially at night.
- Trouble seeing objects up close. For example, you can't see well enough to read newspaper print.
- Aching eyes, eyestrain, and headaches.
Children
with this problem may have no symptoms. But a child with more severe
farsightedness may:
- Have headaches.
- Rub his or her eyes often.
- Have trouble reading or show little interest in reading.
It can be corrected by using appropriate contact lenses and eye glasses. Apart from that surgical options are also available
