What Is Hyperopia?

Hyperopia, commonly known as long-sightedness or farsightedness, is a refractive condition in which the eye needs additional focusing effort to obtain clear vision, particularly at near distances.

People with hyperopia may experience difficulty with reading, mobile phones, computer work or other close visual tasks.

However, hyperopia does not always mean that near vision is blurry.

Younger people can often compensate for some degree of hyperopia by using the eye's natural focusing system, known as accommodation. This means their vision may appear clear even though their eyes are working harder to maintain that clarity.

Depending on the degree of hyperopia, age and individual focusing ability, symptoms can range from no noticeable difficulty to blurred vision, headaches and visual fatigue.

At Eye Zen Optical in Singapore, we provide personalised vision assessments and spectacle solutions based on your prescription, symptoms and everyday visual requirements.

​

What Causes Hyperopia?

For clear vision, light entering the eye needs to be focused appropriately on the retina at the back of the eye.

In an unaccommodated hyperopic eye, the optical system would focus light behind the retina rather than directly on it.

This commonly occurs because the eye is shorter relative to its optical focusing power, although the shape and focusing power of the cornea and lens can also contribute.

The eye's natural focusing system may compensate for some or all of this refractive error, particularly in younger individuals.

This is why hyperopia can sometimes exist even when a person appears to have clear vision.

​

What Does Hyperopia Look Like?

Hyperopia affects people differently.

A person with mild hyperopia and strong accommodation may be able to see clearly at both distance and near.

Someone with a higher degree of hyperopia may experience greater difficulty maintaining clear vision.

Symptoms may also become more noticeable during prolonged near work or as the ability to accommodate decreases with age.

Therefore, hyperopia should not simply be described as:

“Distance clear, near blurry.”

The actual visual experience depends on the interaction between:

hyperopia + accommodation + age + visual demand

​

Common Signs and Symptoms of Hyperopia

Depending on the individual, hyperopia may be associated with:

• Blurred near vision

• Blurred distance vision in higher prescriptions

• Eye strain

• Visual fatigue

• Headaches after reading or computer work

• Difficulty concentrating during prolonged near tasks

• Tired or uncomfortable eyes

• Difficulty maintaining clear vision

• A tendency to move reading material farther away

• Increased discomfort towards the end of the day

Some people with hyperopia may have few or no symptoms, particularly when they are young and have sufficient focusing ability to compensate.

Symptoms such as headaches and eye strain can have many different causes and should not automatically be attributed to hyperopia.

​

Hyperopia and Accommodation

Accommodation is the eye's natural ability to change focus for different viewing distances.

When looking at a near object, the crystalline lens inside the eye changes its optical power to help maintain a clear image.

A person with hyperopia may need to use some accommodation even when looking into the distance.

When they look at something close, additional accommodation is required.

For a younger person with mild hyperopia, this extra focusing effort may happen without obvious difficulty.

However, prolonged visual demand can sometimes contribute to symptoms such as:

• Eye strain

• Headaches

• Tired eyes

• Difficulty concentrating

• Fluctuating clarity

Understanding this relationship is important when assessing hyperopia.

​

Why Can Hyperopia Go Unnoticed?

Hyperopia can sometimes remain unnoticed because the eye's focusing system compensates for it.

Someone may therefore be able to read an eye chart clearly and still have uncorrected hyperopia.

This is particularly relevant in younger people who generally have greater accommodative ability.

As focusing ability changes with age, previously unnoticed hyperopia may become more apparent.

This is one reason why vision should be considered in relation to symptoms and visual demands, rather than relying only on how many letters someone can read on an eye chart.

​

How Is Hyperopia Measured?

Hyperopia is measured during refraction and is normally expressed in dioptres (D).

A hyperopic prescription is generally represented by a plus value.

In general, a larger plus value represents a greater degree of hyperopia.

However, the prescription number alone does not describe the complete visual situation.

Age, accommodation, astigmatism, binocular vision, differences between the two eyes and everyday visual requirements can all influence spectacle prescribing and visual comfort.

​

Can Hyperopia Be Different Between the Two Eyes?

Yes.

One eye can have a different degree of hyperopia from the other.

When there is a significant difference in refractive prescription between the two eyes, this is known as anisometropia.

Significant differences between the eyes may affect visual development in children and can sometimes make binocular vision or spectacle adaptation more challenging.

In these situations, it can be important to consider how the two eyes work together rather than simply correcting each eye independently.

​

Hyperopia and Astigmatism

Hyperopia and astigmatism are different refractive conditions, although they commonly occur together.

Hyperopia relates to the overall focusing relationship between the eye's optical power and its length.

Astigmatism occurs when the optical system has different focusing powers in different meridians.

A spectacle prescription can therefore contain correction for both hyperopia and astigmatism.

Accurate assessment of both components is important when determining an appropriate spectacle prescription.

​

Hyperopia and Binocular Vision

Because people with hyperopia may need to use additional accommodation to maintain clear vision, hyperopia can sometimes interact with the way the two eyes coordinate.

Accommodation and convergence — the inward movement of the eyes when viewing near objects — are neurologically linked.

For this reason, the relationship between refractive correction, accommodation and binocular vision may be relevant in some individuals.

This does not mean that everyone with hyperopia has a binocular vision problem.

However, when someone continues to experience headaches, eye strain, double vision or visual discomfort despite apparently clear eyesight, looking beyond visual acuity alone may be important.

​

Hyperopia in Children

Children can have hyperopia without complaining of blurred vision.

Because young eyes generally have strong accommodative ability, a child may compensate for some degree of hyperopia.

However, significant hyperopia can be important during visual development.

Depending on the child and degree of hyperopia, it may be associated with visual difficulties and, in some cases, conditions such as strabismus or amblyopia.

Children with suspected refractive errors, eye turns, reduced vision or other visual concerns should receive an appropriate professional eye examination.

​

Hyperopia and Esotropia

In some children, significant hyperopia can be associated with an inward eye turn known as esotropia.

Because accommodation and convergence are linked, the additional focusing effort required to compensate for hyperopia can sometimes be accompanied by excessive inward movement of the eyes.

This relationship is not present in everyone with hyperopia.

Children with an eye turn should be appropriately assessed by a qualified eye-care professional rather than assuming that spectacles alone will resolve the problem.

​

How Are Spectacles Used to Correct Hyperopia?

Hyperopia is commonly corrected using plus-powered spectacle lenses.

These lenses alter the path of incoming light so that less accommodative effort is required to obtain clear vision.

The appropriate correction depends on factors such as:

• Degree of hyperopia

• Age

• Symptoms

• Accommodation

• Distance and near requirements

• Astigmatism

• Differences between the two eyes

• Binocular vision

• Previous spectacle experience

For this reason, spectacle prescribing for hyperopia is not always simply a matter of inserting the measured plus power into a pair of glasses.

​

Why Can New Hyperopic Glasses Feel Different?

Someone wearing plus-powered lenses for the first time may notice that their vision feels different.

This is particularly possible when there has been a significant change in prescription or when someone has spent many years compensating for uncorrected hyperopia.

Factors affecting adaptation may include:

• Amount of prescription change

• Age

• Previous spectacle prescription

• Accommodation

• Differences between the two eyes

• Lens design

• Optical centration

• Frame positioning

• Individual visual adaptation

Some adaptation may be expected with a new prescription, but persistent or significant discomfort should be reviewed.

 

Hyperopia and Presbyopia — Are They the Same?

No.

Hyperopia and presbyopia can both make near vision more difficult, but they are different conditions.

​

Hyperopia

Hyperopia is a refractive condition related to the optical characteristics and length of the eye.

It can occur at any age.

​

Presbyopia

Presbyopia is an age-related reduction in the eye's ability to accommodate effectively for near vision.

It generally becomes noticeable during adulthood as near focusing ability gradually decreases.

A person can have:

• Hyperopia without presbyopia

• Presbyopia without hyperopia

• Both hyperopia and presbyopia

When both are present, the spectacle prescription needs to account for the individual's distance and near visual requirements.

How Eye Zen Optical Approaches Hyperopic Spectacle Prescriptions

At Eye Zen Optical, we consider more than whether you can read the smallest line on an eye chart.

Our aim is to understand how comfortably you are seeing and how your prescription relates to your everyday visual requirements.

Depending on your situation, we may consider:

​

Your Symptoms

Do you experience headaches after reading?

Do your eyes feel tired after computer work?

Does your vision become less comfortable towards the end of the day?

Understanding your symptoms can provide important context.

​

Your Prescription

We assess the refractive correction required and consider astigmatism or differences between the two eyes where relevant.

​

Your Previous Spectacles

Previous prescriptions and your experience wearing them can be particularly useful when determining why a new pair of spectacles feels different.

​

Your Distance and Near Requirements

Reading, mobile phones, computer work, driving and general everyday activities place different demands on the visual system.

​

Your Lens Design

The appropriate lens solution depends on your prescription, age and visual requirements.

​

Frequently Asked Questions

Is hyperopia the same as long-sightedness?

Yes.

Hyperopia is commonly known as long-sightedness or farsightedness.

​

Does hyperopia mean distance vision is always clear?

No.

This is a common oversimplification.

People with mild hyperopia may maintain clear distance and near vision using accommodation, while higher levels of hyperopia may cause blur at both distance and near.

​

Can hyperopia cause headaches?

Hyperopia can be associated with headaches or eye strain in some individuals because additional focusing effort may be required.

However, headaches have many possible causes and should not automatically be attributed to refractive error.

​

Can children have hyperopia?

Yes.

Some degree of hyperopia can occur in children, and younger eyes may compensate for it using accommodation.

Significant hyperopia or associated visual problems should be professionally assessed.

​

Can hyperopia cause an eye turn?

Significant hyperopia can be associated with certain forms of inward eye turn, particularly in children.

An eye turn should be professionally assessed.

​

Is hyperopia the same as presbyopia?

No.

Hyperopia is a refractive condition that can occur at any age.

Presbyopia is the age-related reduction in near focusing ability.

​

Can you have hyperopia and astigmatism together?

Yes.

A spectacle prescription can contain both hyperopic and astigmatic correction.

​

Why did I not notice my hyperopia when I was younger?

Younger eyes generally have greater accommodative ability and may compensate for some hyperopia.

As focusing ability changes with age, the hyperopia may become more noticeable.

​

Can glasses correct hyperopia?

Spectacles are commonly used to correct the refractive error associated with hyperopia.

The appropriate prescription depends on the individual's age, symptoms, accommodation and visual requirements.
