Hyperopia (hypermetropia) is a visual impairment in which the focal point from the light rays of the considered the object is behind the retina. With this pathology, a person sees objects absolutely poorly at close range. When the object is removed, the visibility becomes clearer and more distinct, especially at a young age. However, with the gradual progression of the disease and with increasing age of the patient, the lens loses its elasticity, and, as before, cannot compensate for the shortcomings of the optical system. Therefore, often during the diagnostic examination, the so-called latent hypermetropia is detected, to which the patient became sensitive only after 45-50 years.
Hypermetropia, including age-related hypermetropia, is diagnosed quite often and is among the common pathologies of the organ of vision, along with astigmatism, strabismus, myopia, cataracts, keratoconus and glaucoma. If farsightedness is diagnosed at an early stage, then in most cases there is a high chance of restoring visual acuity. Clinic specialists recommend correcting the pathology for both children and adults, including age-related farsightedness. Surgical or hardware correction helps to improve the patient's quality of life.
The lack of timely treatment of high-grade farsightedness (hypermetropia) can cause a number of serious complications, including:
- Glaucoma
- Amblyopia (when one eye sees worse than the other).
- Inflammation of tissues in the eye.

Reasons
The main cause of farsightedness, as well as myopia, is a change in the anteroposterior size of the eyeball. But if in the second case this size increased, then with hypermetropia it decreases, that is, the eyeball becomes flattened along the longitudinal axis.
The next reason is the insufficient optical power of the cornea, with a normal size of the eyeball. In this case, the cornea does not sufficiently refract the rays coming from the object, and they are concentrated behind the retina.
The third reason for farsightedness is a dysfunction of the lens. It loses its elasticity, poorly refracts light rays and cannot focus them on the retina (weak accommodation). With age, the patient begins to notice not only poor near vision, but also deterioration of long-distance vision. Thus, latent hypermetropia is revealed after 45-50 years. And it comes as a surprise to the patient that he needs correction not only for reading, but also correction with plus glasses for the distance.
A separate point is the so-called senile farsightedness, or presbyopia, mistakenly called refractive pathology. It is the process of presbyopia that is a manifestation of the absolute norm after the age of 45-50 years. The need for reading glasses at this wonderful age appears in every person, not even suffering from myopia or hypermetropia.
The main manifestations of farsightedness
There are three degrees of hypermetropia:
- Weak - up to +2 D;
- Medium - +2.25 to +5 D;
- High - over +5.25 diopters.
At a young age, when the optical system of the eye functions well and the lens copes with accommodation, vision is practically not disturbed. However, indirect signs may indicate the presence of hypermetropia: rapid fatigue when reading (especially text with small print), discomfort in the eyes (pain, burning, feeling of pressure), headaches, dizziness, nausea after prolonged visual stress (reading, working at a computer) .
With age, visual impairment joins these symptoms, when close objects are poorly visible, and distant objects are clearly visible. With the progression of the disease, the ability to see into the distance worsens.
The modern ophthalmological equipment of the "K+31" center in Moscow allows diagnosing the disease at an early stage and choosing a treatment that prevents pathological changes and tissue degeneration. For this, it is important to timelygo for a preventive checkup. Leave a request using the form on the site.
