Farsightedness, also known as hyperopia, is a common vision problem affecting people of all ages. It is an eye condition that causes blurry vision when looking at things close up (like words in a book). You may also have headaches or eye strain.
In this comprehensive guide, we’ll cover everything you need to know about farsightedness, including its symptoms, causes, related refractive errors, and available treatment options.
What is Farsightedness (Hyperopia)?
Farsightedness, or hyperopia, is a refractive error that occurs when the eye focuses light behind the retina instead of directly on it. This results in difficulty seeing nearby objects clearly, while distant objects may still appear sharp.
Farsightedness is not an eye diease, it is an eye focusing disorder.
It can occur in one or both eyes and is usually genetic. It often runs in families, with some people being more prone to it than others. Some people may develop farsightedness over time due to age-related changes, such as presbyopia (the loss of elasticity in the eye lens).
How common is Farsightedness?
Farsightedness is relatively common, affecting an estimated 5 to 10 percent of the U.S. population. It can occur at any age, though it is more commonly diagnosed in people over the age of 40. According to a study conducted by the National Eye Institute (NEI), roughly 8.4 million people in the United States aged 40 and above have hyperopia. Please refer to this source for further information.
Global estimates suggest that roughly 1 billion people, or about 1 in 7 individuals worldwide, are affected by this condition.
What are the Symptoms of Farsightedness (Hyperopia)?
Individuals with farsightedness may experience several symptoms. These include:
- Difficulty focusing on nearby objects
- Blurry vision, particularly when reading, sewing, or working at a computer
- Squinting to see clearly
- Eye strain, discomfort or headache after close-up work
- Burning or aching eyes
- General discomfort or headache after prolonged periods of focusing on a task
- In children, there might be an issue with academic performance due to difficulty seeing the blackboard or reading materials.
Again, it’s important to note that these symptoms can vary from person to person. If you’re experiencing any of these symptoms, it is recommended to consult with an eye care professional for a comprehensive eye examination.
What causes farsightedness (Hyperopia)?
Farsightedness, or hyperopia, is primarily caused by a mismatch in the eye’s physical length and its optical length. This mismatch can happen due to the following:
- Short Eyeball: This is the most common cause of farsightedness. When the eyeball is shorter than normal, light rays focus beyond the retina, leading to blurry images of close objects.
- Flat Cornea: The cornea’s curvature plays a significant role in focusing light onto the retina. A flatter cornea is not able to effectively focus the light, causing hyperopia.
- Lens Issues: If the lens inside the eye is not as powerful as it needs to be, light can be focused beyond the retina, causing farsightedness.
- Ageing: As we age, the eye’s lens loses its flexibility, making it harder to focus light on the retina, leading to problems such as presbyopia, which is a form of farsightedness.
Again, it’s important to note that these factors can vary from person to person, and having one or more of these does not guarantee that one will develop hyperopia.
How the Farsightedness is Diagnosed?
Farsightedness (hyperopia) can be easily diagnosed with the help of a comprehensive eye exam. During the exam, your eye doctor will check your vision, measure your refractive error and examine the internal structure of your eyes.
Your eye doctor may also perform additional tests to confirm the diagnosis. These include using a retinoscope or lensometry, which measures the refraction (light bending) of your eyes.
Your doctor may also ask you to read an eye chart or look at pictures that contain different sized objects. He or she may use a slit-lamp microscope to examine the internal structure of your eye in detail.
Farsightedness (Hyperopia) as a Refractive Error: Other Refractive Errors
Farsightedness is one of several refractive errors that can affect vision. Other common refractive errors include:
1. Nearsightedness (myopia): Difficulty seeing distant objects clearly, while nearby objects appear sharp.
2. Astigmatism: Blurry or distorted vision at all distances due to an irregularly shaped cornea or lens.
3. Presbyopia: Age-related difficulty focusing on close objects, usually affecting individuals over the age of 40.
What are the Treatment Options for Farsightedness (Hyperopia)?
Several treatment options are available to correct farsightedness, including:
1. Eyeglasses: Prescription lenses can help focus light correctly on the retina, improving vision for close-up tasks.
2. Contact lenses: Contacts provide an alternative to glasses for correcting farsightedness and may offer better peripheral vision.
Frequently Asked Questions
Q: Is Farsightedness (Hyperopia) Contagious?
A: No, farsightedness is not contagious and cannot be spread from person to person. It is a refractive error that can occur in one or both eyes, usually as a result of genetic factors.
Q: Can farsightedness (hyperopia) be corrected without surgery?
A: Yes, farsightedness can usually be corrected with eyeglasses or contact lenses. Laser eye surgery procedures are also available for more severe cases of hyperopia, but they are typically only recommended if other treatments do not work.
Q: What lifestyle changes can I make to reduce the risk of developing farsightedness (hyperopia)?
A: Although the exact cause of farsightedness is not known, some lifestyle changes can help reduce the risk. These include eating a healthy diet rich in antioxidants, wearing sunglasses when outdoors to protect the eyes from ultraviolet radiation, and taking regular breaks while working or reading to reduce eye strain. Additionally, if you have a family history of farsightedness, it’s important to get your eyes checked regularly and follow your eye doctor’s advice.
Q: Are there any risks associated with laser eye surgery for farsightedness (hyperopia)?
A: Yes, as with any surgery, there are some risks associated with laser eye surgery. These include infection, dry eyes, undercorrection and over-correction of the vision, glare or halos around lights, double vision, and increased sensitivity to light. Thus, it’s important to discuss any potential benefits and risks with your eye doctor before deciding on a course of treatment.
Q: Is farsightedness (hyperopia) more common in men or women?
A: Farsightedness is equally common in both men and women, but it tends to become more pronounced with age for both genders. Additionally, certain ethnicities have been found to be more likely to develop hyperopia, such as Caucasians and Africans.
Q: Will my vision improve with age if I’m farsighted?
A: Unfortunately, the opposite is true for people who are naturally farsighted. Over time, the refractive error often worsens due to normal age-related changes in the eye’s structure. However, this can be corrected with eyeglasses or contact lenses, and in some cases, laser eye surgery.
