This visual impairment affects one in ten people in the world.

What is farsightedness

Farsightedness Farsightedness - Symptoms and causes - Mayo Clinic (or hyperopia) is a condition in which a person clearly sees distant objects in detail. But the closer the object, the more blurry it becomes. This is a common violation.

Most healthy children with Hyperopia are born with mild hyperopia, which decreases with age.

By one year, only 3 out of every 100 children suffer from hyperopia. But when a person gets older, hyperopia may return. By the age of 40, 10% of the world's population faces this problem, and between the ages of 45 and 65, hyperopia is even more common than its antagonist, myopia.

Why hyperopia is dangerous

This visual impairment reduces the quality of life. It is difficult for a farsighted person to read, work with a laptop or smartphone, knit, and perform small actions that require attention with their hands.

But in hyperopia, if it is not corrected, other, even more unpleasant consequences are possible Farsightedness - Symptoms and causes - Mayo Clinic.

• Strabismus. Infants with pronounced hyperopia may develop strabismus by the age of 4 years. Its risk is 13 times higher for Hyperopia than for other children.
• Headaches, early appearance of wrinkles around the eyes. These are the results of the strain that the eyes experience when a farsighted person tries to look at close objects.
• Decreased performance, learning difficulties.
• Decreased security level. Even slicing bread or cheese for a farsighted person can be a dangerous test: one inaccurate movement and a cut.

What are the causes of hyperopia

It's all about the form of Farsightedness: Causes of Hyperopia of the eye, due to which the so-called refractive error (the refractive power of the optical system) occurs.

In normal vision, light entering through the lens and the convex cornea that protects it is focused strictly on the retina. Thanks to this, we see a clear, bright picture.

But if the eye has a cornea that is too flat or its length (the distance between the lens and the retina) is too short, the light rays are focused behind the retina. And the retina only catches a defocused, blurry image.

A short eye is common in very young children. However, their lens can change shape, thicken in order to focus the image strictly on the retina. This ability is called accommodation. In addition, in infants, the eyes grow, become longer, and farsightedness most often disappears.

But with age, the cornea can flatten, and the lens loses its ability to accommodate. This is how hyperopia occurs.

How to recognize hyperopia

If the refractive error is small, the symptoms of hyperopia may be absent. But for more serious problems with the shape of the eye, you will notice Farsightedness - Symptoms and causes - Mayo Clinic is what.

• If you need to examine an object up close, you have to squint, strain your eyes.
• You regularly have headaches or extreme fatigue. Especially after you have been focusing on close objects for a long time, for example, reading, writing, sewing.
• You often encounter symptoms of eye strain: burning in the eyes, the desire to rub them.

If you have these symptoms, be sure to consult an ophthalmologist. The doctor will check your vision using a standard diagnostic chart, if necessary, carry out other tests and make an accurate diagnosis.

How to treat hyperopia

It is impossible to lengthen an eye that is too short. However, hyperopia is quite amenable to Farsightedness correction.

The easiest and fastest way is to choose the right glasses or contact lenses. These lenses have a convex shape that compensates for a too flat cornea and helps focus the image strictly on the retina.

In some cases, a surgical operation is prescribed, with the help of which the shape of the cornea is changed.

Which of the options will be more effective in your case, only a doctor will tell you.

Also, your doctor may advise you to do special eye exercises or take vitamins. But be warned: there is no Farsightedness. Treatment of sufficient scientific evidence that these methods will help restore vision.

How to prevent or slow down hyperopia

Farsightedness cannot be prevented. But you can protect the Farsightedness of the eye from damage that can affect the quality of vision.

• Protect your eyes from ultraviolet radiation. Be sure to wear sunglasses in bright sunlight.
• Protect your eyes from injury. Wear safety goggles if you plan on jogging on a dusty street or mowing the lawn. Or, let's say, you are going to paint a fence.
• Keep chronic illnesses under control. Certain disorders, such as hypertension or diabetes, can impair vision if left untreated.
• Avoid eye strain. Look away from your computer or book every 20 minutes to focus on distant (at least 6 m from you) objects. Consider them for at least 20 seconds.
• Stop smoking. Smoking is harmful to the body in general and to vision in particular.
• Get regular checkups with an ophthalmologist. Children must have an eye exam before the first grade and every two years during the school period. Check your eyes every 2–4 years between ages 40 and 54, every 1–3 years between ages 55 and 64, and every 1–2 years after age 65.
