As one of the most common vision conditions, farsightedness gives headaches to millions of people around the world.
Clinically known as hyperopia, it causes people to have difficulty seeing objects up close, but generally have clearer vision at a distance.
Here, we explore all about farsightedness, covering:
- Detailed explanation of farsightedness
- Typical symptoms, causes, and diagnosis
- Treatment options for farsightedness
along with all the frequently asked questions and their answers to help you better understand all the details of farsightedness (hyperopia).
Farsightedness (Hyperopia) Explained
Farsightedness, also known as hyperopia, is a common vision condition where distant objects can be seen more clearly than those that are close up.
This happens because of the way light enters the eye, focusing behind the retina instead of directly on it.
Imagine the eye as a camera. For a clear picture, the camera must focus light directly onto the film. In the eye, the retina acts like this film.
With hyperopia, your eye shape causes light to focus behind this "film," making nearby objects seem blurry.
The shape of the eye plays a crucial role in farsightedness or hyperopia, as the eye should be perfectly round ideally.
However, if the eye is too short from front to back, or if the cornea (the clear front cover of the eye) is too flat, light doesn't bend (refract) properly.
The result is a focus point behind the retina, which leads to blurry vision for close objects. It is often present from birth, but many people may not notice any issues until they are adults.
If you have hyperopia, you may experience difficulties in close-up tasks like reading as it becomes challenging without corrective measures.
Understanding farsightedness is the first step towards managing it effectively.
With proper diagnosis and treatment through eyeglasses, contact lenses for farsightedness, or surgery, you can see clearly at all distances.
Symptoms of Farsightedness
The primary symptom of farsightedness is blurred vision that's more noticeable when looking at close objects.
This can make everyday tasks such as reading, using a smartphone, or detailed craftwork quite challenging.
In such cases, you might notice that you need to hold books, smartphones or other objects further away to see clearly.
In addition to blurred near vision, other common symptoms include:
- Aching or burning eyes
- Eye strain, especially after activities involving close focus
- Headaches following extended periods of doing close tasks
These symptoms may not be constant and can vary depending on your level of focusing effort and the distance of the objects you are viewing.
Causes of Farsightedness
Farsightedness is typically due to the eye’s shape affecting how light is focused. There are two main anatomical causes:
- Short Eyeball: If the eyeball is shorter than normal, it causes the lens of the eye to focus images behind the retina instead of directly on it.
- Flat Cornea: The curvature of the cornea can also influence light focus. A flatter cornea results in light being focused further back, beyond the retina.
Farsightedness is often genetic, meaning it can be passed down through families.
Additionally, environmental factors and health conditions like diabetes can influence the shape of the eyeball or the flexibility of the lens.
Another aspect of vision that can impact people with hyperopia is difficulty in switching focus between distances.
For example, you may find it particularly difficult to shift your gaze from something close to a distant object quickly, which can be essential in activities like driving.
By understanding the symptoms and underlying causes of farsightedness, you can seek timely medical advice and appropriate treatments to manage the condition effectively.
Diagnosis of Farsightedness
Here is a sample process for diagnosing farsightedness:
Recognizing the Need for an Eye Exam for Hyperopia
If you suspect you might be farsighted, the first step is to schedule a comprehensive eye exam.
During this exam, you’ll undergo several tests that help your eye care professional determine not just how well you see, but also the specific characteristics of your vision challenges.
What Happens During an Eye Exam for Farsightedness?
- Vision Tests: You’ll be asked to read letters from a chart positioned at a distance to measure your visual acuity. This helps determine how well you can see at various distances.
-
Refraction Assessment: This test is crucial for identifying farsightedness. Using a device called a phoropter, your eye doctor will place various lenses in front of your eyes.
You’ll give feedback on which ones make the vision chart appear clearest. The lens power that provides the best clarity will help determine the degree of your hyperopia. - Eye Health Evaluation: Your eye doctor will examine the internal and external health of your eyes. This may involve dilating your pupils to get a better view of your eye's structures, including the retina and optic nerve.
Understanding the Diagnosis of Hyeropia
Based on these tests, your eye doctor will be able to tell you if you are farsighted and to what degree.
They’ll discuss your options for correcting your vision, whether through glasses, contact lenses, or possibly surgery.
Getting a proper diagnosis is key to ensuring you receive the right treatment, allowing you to enjoy clearer vision and a better quality of life.
The Best Options for Farsightedness (Hyperopia) Treatment
Treating farsightedness is essential not only for clear vision but also for overall eye health and comfort.
When it comes to farsightedness treatment, there are several effective options available, each tailored to different needs and lifestyle preferences:
Contact Lenses and Glasses for Farsightedness
Prescription contact lenses and eyeglasses are the most common methods for correcting farsightedness. They work by adjusting how light rays enter the eye, ensuring they focus directly on the retina.
- Eyeglasses: With specialized lenses, eyeglasses can correct vision effectively. However, this may not be the best option if you prioritize comfort and convenience.
- Contact Lenses: These provide more natural vision and do not affect appearance. They can be more suitable if you have an active lifestyle. They come in various types, including disposable, extended-wear, and multifocal options.

Surgery for Hyperopia (Farsightedness)
Surgery is just another option, especially if you are looking to correct farsightedness permanently. The choice of procedure often depends on the degree of hyperopia and the specific vision needs.
For example, the LASIK eye surgery is ideal if you have lower degrees of hyperopia. It uses a precision laser to reshape the cornea, allowing light to focus correctly on the retina.
The procedure is quick, and most patients experience rapid improvement in vision.
Similar to LASIK but without creating a flap in the cornea, PRK (Photorefractive Keratectomy) is often recommended for patients with thinner corneas.
Both surgical options aim to enhance vision clarity and reduce dependency on glasses or contact lenses.
If you consider surgery, you should discuss your options with an eye care professional to determine the best approach based on your unique conditions and lifestyle.
Frequently Asked Questions about Farsightedness (Hyperopia)
Here are some of the most common questions about farsightedness:
What is farsightedness (hyperopia)?
Farsightedness (hyperopia) is a common refractive error in the eye that causes distant objects to be seen more clearly than nearby objects. This occurs when the cornea or lens doesn't bend light properly to focus images directly on the retina.
What is the difference between farsightedness and astigmatism?
Farsightedness occurs when your eyeball is too short relative to the focusing power of your cornea and lens, causing light to focus behind your retina. This results in difficulty seeing objects up close.
Astigmatism, on the other hand, is caused by an irregular curvature of the cornea or lens, which leads to distorted or blurred vision at all distances because light rays don’t meet at a common focus.
What are the symptoms of farsightedness?
The symptoms of farsightedness may include difficulty seeing up close, eyestrain, headaches, and blurred vision when looking at objects up close.
How can farsightedness be treated?
Farsightedness can be corrected with eyeglasses or contact lenses, and in some cases, refractive surgery such as LASIK may be an option to improve vision.
Does farsightedness get worse with age?
Farsightedness can change as you age. Many people find that their ability to focus on close objects declines over time, especially after the age of 40.
This change is due to presbyopia, an age-related condition that affects everyone to some degree and involves the hardening of the lens inside the eye.
As the lens becomes less flexible, it can no longer change shape as easily to focus on near objects. If you're already farsighted, presbyopia can exacerbate your difficulties with near vision, making it seem as though your farsightedness is getting worse.
It's important to have regular eye exams to monitor these changes in your vision so that adjustments can be made to your vision correction as needed.

How often should I get their eyes checked if I have farsightedness?
It’s recommended that adults with farsightedness have a comprehensive eye exam every one to two years.
However, if you notice significant changes in your vision or experience discomfort, you should schedule an appointment sooner.
For children, regular eye exams are crucial as their eyes are still developing, and undiagnosed vision problems can affect learning and development.
What causes farsightedness?
Farsightedness is usually caused by the cornea or lens having a flatter curve than normal, which results in light entering the eye focusing behind the retina instead of directly on it.
At what age does farsightedness typically occur?
Farsightedness may develop at any age, but it is more common in individuals over age 40 and can worsen with age.
What are the signs and symptoms of severe farsightedness?
Severe farsightedness may lead to significant blurry vision at all distances, eye strain, and headaches.
Can children also have farsightedness?
Yes, children can also have farsightedness, which may affect their ability to see objects up close
