What is hyperopia?
Farsightedness, or hyperopia, is an eye condition where far away objects are easier to see than near objects.
Why does hyperopia occur?
If the length of your eyeball is too short or the cornea isn’t rounded enough, close objects need more focusing effort to be brought into clear focus on the retina. Hyperopia may be passed on from parents or it may result from environmental factors.
How does hyperopia affect vision?
If you are farsighted, it takes extra effort for the eyes to see far away objects clearly and even greater effort to see objects up close. This extra effort can cause fatigue, tension, discomfort and headaches. If the lens of the eye cannot bring the object into focus, blurred vision occurs.
How common is hyperopia?
Many people have some degree of hyperopia without knowing it! The condition may only become a problem if it significantly affects your ability to see. However, symptoms can be avoided by seeing your doctor of optometry regularly to assess your eyes and prescribe glasses if you need them.
It is estimated that over half the people who wear glasses are wearing them because of a focusing problem due to hyperopia or presbyopia, a natural decrease in focusing ability that occurs with age.
What are the signs/symptoms of hyperopia?
Common signs and symptoms of hyperopia include:
- difficulty concentrating and maintaining a clear focus on near objects,
- blurred vision,
- eye strain, fatigue and/or headaches after close work,
- aching or burning eyes,
- poor reading ability, and
- general tension.
How is hyperopia detected?
Farsightedness can be effectively diagnosed during a comprehensive optometric examination.
Sight testing and common vision screenings, often done in schools, are generally ineffective in detecting people with hyperopia. This is because these individuals can identify the letters on an eye chart in the distance with little difficulty.
How is hyperopia treated?
In mild cases, your eyes may be able to compensate without the need for corrective lenses for distance, although glasses for reading and computer use may be helpful.
In more severe cases, your doctor of optometry may recommend glasses or contact lenses for full-time wear. Some people may be eligible to consider laser surgery.
How will hyperopia affect my lifestyle?
If glasses or contact lenses are prescribed, it may take a few days to adjust to them. After that, farsightedness will probably not significantly affect your lifestyle.
