Eye Problems Hyperopia

Hyperopia, also known as hypermetropia and farsightedness, is a vision defect caused when a person’s eyeball is too short or when a person’s lens is not round enough. Hyperopia causes incoming light rays to reach the eye’s retina before they become a focused image. This creates blurred vision.

People who are affected by hyperopia can typically see objects that are far away but not objects that are very close. The condition is present in about 1/4 of the population.

Signs of hyperopia include:

  • blurry vision
  • eye strain
  • fatigue
  • headaches
  • squinting.

Causes of Hyperopia

Hyperopia in children is quite common, and the majority of people who have this condition are born with it. While some children will outgrow hyperopia over time, as their eyeballs will lengthen as they mature, others continue to suffer from this condition through adolescence and adulthood. There is no known way to prevent hyperopia from occurring.

In addition to age, an individual’s genetic makeup is also known to contribute to hyperopia. People who have a family history of hyperopia are more at risk of developing the condition than those who do not.

Hyperopia of the Eye

Hyperopia Diagnosis

To diagnose hyperopia, an eye doctor will need to perform a routine eye exam. During the exam, the doctor will ask about your medical history and your family medical history, will perform a vision test and will use special instruments to look inside your eye.

To make a hyperopia diagnosis, he might also need to use cycloplegic drops. These drops dilate the eye and prevent the lens from changing shape, allowing the doctor to determine whether or not you are farsighted.

The drops will make your vision blurry, especially when you are reading or driving, for several hours. Therefore, you shouldn’t drive yourself home from your eye exam.

In some cases, hyperopia has been shown to increase a person’s probability of experiencing chronic glaucoma. Although vision loss associated with glaucoma is preventable, those who suffer from hyperopia should be aware of this side effect and discuss treatment options with their eye care professionals.

Hyperopia Treatment

Hyperopia is most commonly treated with prescription glasses or contact lenses. Many people who are treated for hyperopia need to wear prescription glasses or contact lenses only when they are driving, working or reading.

While some minor instances of hyperopia can remain untreated without side effects, many people seek care or treatment to lessen the symptoms of hyperopia.

Other Treatment Options: Hyperopia Surgery

Eye care professionals may recommend refractive surgery, such as LASIK or CK (conductive keratoplasty) for hyperopia. In one relatively new hyperopia eye surgery, a corrective contact lens is implanted behind the iris of the patient’s eye. This effectively focuses the light before it reaches the retina, helping alleviate hyperopia.

Hyperopia eye surgery can sometimes correct the condition altogether but will, at the very least, noticeably decrease the symptoms of hyperopia.

Many different methods of surgery for hyperopia are currently being studied, and people who have low to moderate hyperopia can achieve fully corrected vision in some cases.
