Hyperopia
Unlike short-sightedness, with long-sightedness the eye has to constantly „work” to bring the image into focus — which is why the symptoms are often linked to eye strain, rather than simply blurred vision.
What is hyperopia?
Hyperopia is a refractive error in which the eye focuses light rays behind the retina, rather than directly on it. As a result, the image is not focused correctly.
Contrary to popular belief, hyperopia does not simply mean difficulty with close reading. In fact, it can affect both near and distance vision — particularly when the refractive error is larger or the eyes are already tired.
A person with hyperopia can often function without glasses for a long time, as the young eye is able to compensate through intensive accommodation. Over time, however, this mechanism is no longer sufficient. It is worth distinguishing between hyperopia and presbyopia. Hyperopia is due to the structure of the eye, while presbyopia is the natural ageing process of the lens.
How does hyperopia affect your daily life?
At first you may not even notice it. However, as time passes, you may experience a sense of constant visual effort. Reading, working at a computer or using a smartphone begin to require more concentration.
An eye that has to constantly adjust its focus works harder than it should. This leads to fatigue, headaches and reduced visual comfort — even if distance vision still appears good. Long-term accommodative overload can cause chronic headaches, reduced productivity at work and a persistent feeling of fatigue, even when the refractive error is not severe.
Symptoms of hyperopia
How do you recognise it?
The primary symptom is deterioration of near vision. However, the range of complaints can be wider.
In some patients, hyperopia only becomes apparent when the ability to accommodate begins to decline, which is sometimes mistakenly interpreted as a „sudden deterioration in vision”.
Blurred image when reading
Particularly in fine print or low light conditions
Forehead pain
Associated with prolonged tension of the eye muscles
Eye fatigue (asthenopia)
Burning, tearing, feeling of „heavy eyelids”
Reduced screen comfort
Need for frequent breaks and difficulty maintaining focus
Causes of hyperopia
What causes the eye to become hyperopic?
The development of hyperopia is mainly due to the anatomy of the eye. In most cases, it has a genetic basis.
Influence of genes and eye structure
If there is a family history of hyperopia, the risk of developing it is higher. The eyeball may be shorter than average or the corneal curvature insufficient to focus light correctly.
Age-related changes
As the years go by, the lens of the eye loses its elasticity. The ability to accommodate diminishes, and a previously compensated refractive error starts to become noticeable.
Co-existing conditions
In some cases, hyperopia may occur alongside other conditions, such as strabismus or accommodation disorders.
The role of accommodation
At a young age, the lens of the eye is very flexible and can adjust focus even with an existing refractive error. However, this mechanism works at the expense of constant tension in the eye muscles.
With time, accommodation weakens and the symptoms of hyperopia become more pronounced. This is why many people only begin to experience discomfort in their 30s or 40s.
Types of hyperopia
Several types are distinguished in clinical practice:
Axial hyperopia
It results from a shortened length of the eyeball. It is the most common form of hyperopia.
Curvilinear hyperopia
Associated with insufficient curvature of the cornea or lens. May be congenital in nature.
Latent hyperopia
Masked by strong accommodation, it often only becomes apparent with age.
Degrees of refractive error
Low refractive error
Usually does not exceed +2.0 D. It often goes unnoticed for a long time because the young eye compensates through accommodation.
Moderate refractive error
Ranges from approximately +2.0 to +5.0 D and usually causes noticeable discomfort during close work and more rapid eye fatigue.
High refractive error
Exceeding +5.0 D, it can significantly affect the quality of both near and distance vision and requires ongoing ophthalmological follow-up.
How is hyperopia treated?
Treatment begins with a thorough diagnosis. We assess not only the degree of refractive error in dioptres, but also the condition of the cornea, lens and retina and the stability of the refractive error.
Possible approaches include:
- spectacle or lens correction,
- supportive treatment for coexisting accommodative disorders,
- laser vision correction for adults with stable vision problems.
Laser correction of hyperopia involves reshaping the cornea so that light is correctly focused on the retina.
We select the treatment method individually, taking into account the patient's age, eye parameters and lifestyle.
Hyperopia diagnosis
- determines the type and degree of refractive error
- assesses accommodative capacity,
- analyses the structure of the cornea and the length of the eyeball,
- identifies the safest method of correction
Regular eye tests enable the early detection of vision problems and help prevent their consequences.
Frequently asked questions
We will answer all your concerns.
From what degree of refractive error can laser correction of hyperopia be considered?
The procedure is considered in adults with a stable refractive error. Eligibility depends not only on the number of dioptres, but also on the corneal structure, the patient's age and the general condition of the eye. The most important step is a thorough examination.
Can hyperopia be corrected permanently?
In adults with a stable refractive error, permanent correction of hyperopia with laser vision correction is possible — provided the parameters of the eye allow the procedure to be performed safely. The decision is always preceded by a detailed consultation.
Is hyperopia the same as astigmatism?
No. Hyperopia results from an abnormal focus of light behind the retina, while astigmatism is the result of an irregular corneal shape. Both defects can occur simultaneously and require individual correction.
What lenses are used for hyperopia?
Positive power ("+") lenses are used to correct hyperopia, which help to focus light correctly on the retina. The correct power is always determined by an ophthalmologist — self-selecting "plus" lenses can worsen eye fatigue.
Can hyperopia cause headaches?
Yes. Constant tension on the eye muscles as they try to sharpen images can lead to headaches — particularly in the forehead area. Symptoms are worse after working at a computer, reading or focusing at close range for extended periods.
Does hyperopia get worse over time?
The structure of the eye itself does not usually change rapidly. However, the ability to accommodate decreases with age, so a previously compensated refractive error starts to become noticeable. Patients often interpret this as a worsening of the condition, although in fact it is the flexibility of the lens that decreases.
Regular eye examinations help to keep things under control.
How do people with hyperopia see?
With slight hyperopia, distance vision can be good because the young eye is able to compensate. Problems most commonly arise when reading or working up close — the image becomes less clear and the eyes tire more quickly. With a larger refractive error, the deterioration can also affect distance vision.
