Myopia and hyperopia: what is it? Causes, prevention, correction

Sight is probably one of the main feelings.human, because thanks to the eyes people get the most information. In order to see the world with a clear, sharp look, a very complex process takes place in the human body, connected with the eyes and the brain. If the slightest failure occurs in this system, then the vision fails and leads to myopia and hyperopia.

Myopia

Медицинская статистика говорит о том, что каждый The fourth person has problems with myopia. This disease is characterized by the fact that visual acuity decreases and objects that are far away are poorly perceived. This process is associated with large refraction in the optical system of the eye, which does not correspond to the length of its axis. Myopia can develop as a disease and leads to a gradual deterioration in vision. Or it progresses at a certain point, and the vision is constantly in poor condition and does not change over the course of many years.

Hyperopia

This eye disease can be calledopposite to myopia, since the problem of farsightedness is associated with the perception of objects at close range. But, if there is an in-depth problem of farsightedness, then the perception of objects in the far distance is disturbed. This problem occurs because of a short eyeball or a flat cornea. This state does not give the rays of light that enter the eye to refract to the extent that would be sufficient for the focus on the retina. Therefore, the image does not focus on the retina, but behind it. Usually, this disease is characteristic of people over 40 years old, and this problem is also often found in newborns.

myopia and hyperopia what is it

The difference between myopia and farsightedness

In order for a person to be able to normallysee the picture at any distance, the optical axis must have the right direction, and it should focus on the retina. Light rays provide information about an image that is transmitted through the cornea and lens. Further this information is sent to the retina to transform into a nerve impulse. In the brain, which is responsible for the visual apparatus, the beam enters through the optic nerve. In cases where the process of refraction of rays occurs outside the retina, then visual acuity deteriorates, and at the same time it has a different distance.

It should be clearly distinguished between myopia andfarsightedness. What is it already described above in the article, but in simple words we can say that these two symptoms differ in how far you can see.

The causes of myopia and hyperopia

Eye disease in itself does not occur, all of this has its own reasons. In order not to have problems with vision, you need to know how short-sightedness and farsightedness arise.

Causes of myopia:

  1. Heredity. If one of the parents suffers from a similar problem, then there is a high probability that children will also inherit this pathology.
  2. Work at close range.This mainly concerns those people who work a lot with a computer. Schoolchildren who have not yet fully developed an organism are considered the most vulnerable to this problem.
  3. Weakened body This factor includes various health problems: birth injuries, poor immunity, infectious diseases, fatigue and so on.
  4. The shape of the eyeball.
  5. Bad conditions for visual work.

Causes of farsightedness:

  1. Reducing the size of the eyeballs on the front and rear axles.
  2. Age reasonInfants are almost always born with hyperopia problems. In addition, people over 25 years old may already begin to feel blurred vision, but only by the age of 45 this problem becomes pronounced.

Basically, as has been said, the causes of myopia and hyperopia occur throughout life, since many people are exposed to modern environmental conditions.
