Hyperopia is also known as farsightedness. It is a general vision difficulty, affecting almost most of the people. In Hyperopia the eyeball is short from front to back as compared to the normal eyeball, in other words a person can see distant objects very well, but have difficulty seeing objects that are up close.
Exactly why eyeball shape varies is not known, but the tendency for farsightedness is inherited. Other factors may be involved too, but to a lesser degree than heredity.
Hyperopia Symptoms and Signs –
Sometimes Farsighted people have headaches or eyestrain and can strain to see or feel tired when performing work at close range. If you get these symptoms whereas wearing your glasses or contact lenses, you may need an eye exam and a new recommendation.
What Causes Hyperopia?
This vision difficulty occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than usual.
Many children are born with hyperopia, and some of them “outgrow” it as the eyeball lengthens with normal growth.
Sometimes people confuse hyperopia with presbyopia, which also is a difficulty in seeing up close, but have a different cause. If you can see objects at a distance clearly but have trouble focusing well on objects close up, you may be farsighted.
Your eye care practitioner may refer to farsightedness as long sightedness, or by its medical names, hypermetropia or hyperopia. Hyperopia causes the eyes to exert extra effort to see close up. After viewing nearby objects for an extended period, you may experience blurred vision, headaches and eyestrain. Children who are farsighted may find reading difficult.
Hypermetropia is not an infection, nor does it mean that you have “bad eyes.” It just means that you have a variation in the shape of your eyeball. The degree of variation will decide whether or not you will need corrective lenses.
Hyperopia Treatment –
Farsightedness can be cured with glasses or contact lenses to change the way light rays bend into the eyes. If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are farsighted.
You may need to wear your glasses or contacts the entire the time or only when reading, working on a computer or doing other close-up work.
Refractive surgery, such as LASIK or CK, is another option for correcting hyperopia. It might decrease or remove your need to wear glasses or contact lenses
