Hypermetropia

We see well at any distance when our eyes focus images on the retina, when they don't, we will have a visual defect that we will correct with glasses or contact lenses.

What is hyperopia?

Hypermetropia is a change in sight that affects the vision closely. This happens when the eyes focus the images behind the retina, rather than exactly on it.

Symptoms of hypermetropia

Blurred vision closely with difficulty in focusing.

Feeling of eye fatigue.

If hypermetropia is high or low accommodative capacity, blurred vision from a distance.

Headache.

Red eyes.

How is hyperopia developed?

Most children are born with hyperopia, which is corrected by growth until it disappears. It is important to check whether the child keeps hypermetropia, as it can sometimes be difficult to detect it, to avoid other disorders such as amblyopia (lazy eye) or strabismus.

How DO I CORREGATE hypermetropia?

It is corrected by the use of single-phase glasses, spherical lenses or the combination of both. In the specialist's recipe, a sign (+) is identified in front of the sphere's value.

Hypermetropia: What it is and how to treat it

Hypermetropia is one of the most common conditions and, although it tends to be associated with the next vision, its impact on global visual performance is significant. To effectively correct hypermetropia, it is essential to understand its physiological origin and how it affects the accommodative system.

What is hyperopia?

To understand what hypermetropia is, we must analyze the ocular anatomy. This is a refraction error in which light rays that affect the eye focus on a plane after the retina. This phenomenon is usually due to two main factors:

Short antieroposterior axis: The eyeball is shorter than usual.
Insufficient power to power: The cornea or lens do not have the curvature required to convert light correctly.

Unlike myopia, the hypermetrope eye tries to compensate for this deficit by accommodation, a constant effort of the ciliary muscle to vary the shape of the lens and re-focus the image.

How do people who have hyperopia see?

The visual experience of a hypermetrote patient varies according to their age and the magnitude of the defect. There is usually a difficulty in focusing on nearby objects, such as reading or using digital devices.

However, in cases of high hypermetropia or over the years (when the accommodation capacity decreases), vision at distant distances can also be compromised, generating an unstable or fluctuating vision.

Symptoms of hyperopia: Identification and warning signals

Symptoms of hyperopia are not always manifested as a clear blurred vision, due to the ability to compensate the eye. However, continued effort usually triggers:

Astenoplia (Ocular Fatigue): Feeling tired after performing tasks closely.
Front walls: Recurring headaches, especially at the end of the day.
Difficulty approach: Especially when changing the look from a distant plane to a nearby one.
Conjunctival hyperemia (red Eyes): Caused by visual stress and reduced flashing during the effort.
Trabbra or amblyopia in children: If it is not processed in time, excessive effort can cause eye deviations.

How is hyperopia developed? Evolution and diagnosis

It is important to note that most children are born with a degree of "physiological hyperopia" that tends to be reduced during the emetropisation process (eye growth). However, if this defect persists or is excessive, it can interfere with the binocular development.

Professional diagnosis is crucial, as in young patients the visual system can "mask" actual graduation by accommodating, requiring specific refraction tests to determine the exact value of the correction required.

Treatments for hyperopia: Solutions for a clear vision

There are various ways to correct hyperopia and restore visual comfort. The main objective is to move the focus of the image forward, placing it exactly on the retina.

The main treatments for hyperopia include:

Ophthalmic lenses (Goggles): Convergent lenses are used (with positive power, indicated with the sign + in the prescription). These lenses compensate for the lack of eye power, eliminating the need for constant accommodative effort.
Contact lenses: Globe contact lenses offer a complete visual field and a more natural perception, an excellent choice for users with an active life.
Customised Solutions: Depending on the lifestyle, lenses with advanced anti-reflective treatments can be prescribed to reduce fatigue in digital environments.

Frequently Asked Questions on Hyperopia

We then resolve the most common doubts using clinical criteria to help you understand what hyperopia is and how to manage it in your day-to-day life.

What is the technical difference between myopia and hypermetropia?

The main difference lies in the focus point of the image. While in myopia the eye is "too long" and focuses before the retina, in hypermetropia the eyeball is usually shorter or the power of the insufficient cornea, projecting the image behind the retina. This causes hypermetropia to make a constant muscle strain (accommodation) to try to see clearly, even from a distance.

Is it possible to have hypermetropia and presbyopia at the same time?

Yes, and it is a very frequent clinical situation from the age of 40. Presbyopia (tired sight) is the gradual loss of lens elasticity, while hyperopia is a structural refractive error. When both converge, the visual system completely loses its ability to compensate, making symptoms of hypermetropia worse and the need to correct it with progressive lenses is indispensable to maintain comfort.

Are the treatments for hyperopia permanent?

Hypermetropia treatments using optical solutions (glasses and contact lenses) compensate for the defect immediately while they are used, but do not modify the anatomy of the eye. For patients looking for a definitive solution, there are surgical options such as laser (LASIK) or intraocular lenses, although the viability depends on a prior study of the cornea and the stability of the graduation.

Why can hypermetropia cause visual fatigue if "I see well"?

This is one of the most misleading symptoms of hyperopia. Many young hypermetroes have a visual acuity of 100% because their muscle ciliary compensates the defect by a sustained effort. However, this metabolic "overexertion" is what triggers headache and ocular burning.
Therefore, correcting hypermetropia with suitable optical help is essential to relax the visual system, even if the patient feels that their vision is clear.

How does non-corrected hyperopia affect school performance?

The importance of visual health in children is critical. A child with undetected hypermetropia will have difficulty maintaining attention in reading tasks, as the focus effort is quickly exhausted. This can result in school failure or problems with binocular development such as amblyopia. Regular check-ups are the best of the children's visual health tips.
