Hyperopia: causes, symptoms and treatment

Published: Last Updated on

The hyperopia is an eye defect that causes a blurred vision when viewed up close. The person can see correctly from a distance, but as he gets closer or tries to observe an object up close, it is perceived as blurry. It is very common that, in the beginning, hyperopia does not present signs, as well as that it worsens, leading to blurred vision also from a distance with age. The main cause is hereditary and the most obvious symptom of this eye defect is blurred vision at short distances. In this FastlyHealarticle we will explain the causes, symptoms and treatments of hyperopia .

Functioning of the eye

We can compare the eye with a camera to understand how it works. Light penetrates through the cornea, passing through the lens, a kind of lens located just behind the eye, and reaches the retina, the back wall of the eye. The retina absorbs the light rays that are transmitted by the optic nerves until they reach the brain, where the process that allows images to be visualized takes place. The problem of farsightedness lies in a refractive error of the eye , whereby it does not bend the light it receives properly, so the images are not focused clearly and the image is blurred.

Causes of hyperopia

The main cause of hyperopia is hereditary . Many children are born with this eye problem and do not have any signs to indicate it. These have clear vision because the eye adapts by bending light rays and directing them to the retina. In the event that hyperopia continues to develop over time, this is when symptoms may appear; However, on many occasions, hyperopia ends up healing itself after a while, when the child develops sight.

We can differentiate between different causes of hyperopia :

  • The eye diameter is too small. It occurs because the eye is shorter than usual.
  • The optical power of the cornea or lens reduced.
  • Inherited hyperopia.

When farsightedness develops, it can lead to other visual disturbances such as lazy eye or strabismus.

Symptoms of hyperopia

As we explained previously, hyperopia can be asymptomatic initially, so the patient does not present any sign that can alert him to the presence of an ocular defect. When the disease begins to manifest its symptoms, it is common for the patient to experience the following signs:

  • Headache caused by overexertion of the eye.
  • Eye pain.
  • Fatigue.
  • Itchy eyes
  • Blurred vision from afar. In the case where hypermetropia develops. It is common for it to appear with age.
  • Appearance of other eye ailments such as strabismus or amblyopia.

It is common to confuse hyperopia with presbyopia or eyestrain. Presbyopia is a disease of the eye as a consequence of the aging of the lens and the cycliar muscle, responsible for the eye correctly focusing the light perceived through the cornea.

Diagnosis and treatment of hyperopia

At the beginning, detecting hyperopia can be very difficult due to the absence of symptoms, and the fact that the child does not complain about the difficulty of perceiving images. One of the signs that can indicate that the child suffers from hyperopia is that the child gets very close when writing, drawing or watching television. However, it is best to go to the ophthalmologist for a periodic review and detect any abnormalities. In addition, when the child develops eye muscles, changes may occur that generate some loss of vision that must be corrected to prevent it from becoming more serious and increasing.

The treatment of hyperopia can vary depending on the level of loss of visual acuity that the patient presents, as well as other symptoms that may present and that harm health. It is common to use glasses, contact lenses or even surgery to correct the root problem. Glasses are effective, however the prescription has to be changed as farsightedness increases. On the other hand, contact lenses or lenses require good hygiene and maintenance to avoid damage to the eyes, since otherwise it could cause eye infections or other discomfort. In the case of surgery, there are people who are afraid to undergo the intervention, although it is the definitive solution to end blurred vision.
