The eyes are the most important human organ that helps us to see and know the world around us. Unfortunately, in our time, almost everyone sooner or later faces vision problems. This is due to the way of life, technological progress and environmental issues. Consider how the image focuses in the myopic eye. Symptoms, causes and methods of correcting myopia.
What is myopia
Myopia (or myopia) is a disease of the organs of vision, in which objects located at a great distance seem blurred, while close objects look clearly. This is due to the fact that in the myopic eye, the image is focused in front of the retina, and not on it. Nowadays, this is the most common pathology of vision.
The eyes of a person are created to distinguish objects from a long distance. In our age of technological boom, man, on the contrary, constantly strains his eyes by examining objects at close range. In this regard, it is believed that one third of the world's population suffers from myopia. Myopia appears due to an elongation of the eyeball or an increase in the refractive power of the cornea.
How do myopic people see? Objects that are in the distance seem blurry, when approaching, they gain clarity. In this case, rapid eye fatigue, headache, pain and pain in the eyes are possible.
Causes of myopia
Heredity is one of the main causes of myopia. Only 8 percent of children whose parents suffer from myopia have no vision problems. Another significant reason is excessive visual stress. Constant observation of close objects, insufficient lighting, improper posture - all these are the causes of myopia. This problem has become particularly acute in recent years with the introduction of all kinds of mobile gadgets. Other causes of myopia can be: incorrectly selected glasses or lenses, eye injuries , age-related changes in the lens, transformation of the cornea.
Prevention and treatment of myopia
It is noted that the more often a person is in the fresh air, the less likely he is to get ill with myopia. When working in the office for a long time, you should periodically do visual exercises in front of the computer, focusing your attention on distant or near objects. If the first symptoms occur, consult a specialist as soon as possible. It should be remembered that the treatment of diseases that are in the initial stages is most effective.
The following methods are used to correct myopia:
- selection of suitable points;
- contact lenses;
- night lenses;
- intraocular lenses;
- laser vision correction;
- lens replacement.
Thus, myopia is a common visual pathology. Usually, over time, vision only worsens, therefore, at the first manifestations of myopia, it is urgent to consult an ophthalmologist.
