Healthy eyes and excellent eyesight is a dreameach person. But not everyone can boast of this. Practically every person has this or that disease of the eye. And in this article we will consider a disease such as astigmatism: what it is, how to treat and how to avoid it.
Astigmatism is one of the main causes of visual impairment. It can occur in combination with hyperopia and myopia.
From the Latin language, astigmatism can be translated as "the absence of a focal point."
In a healthy eye, the lens and cornea have an even surface of the sphere. When astigmatism occurs, their sphericity is disturbed. Curvature is formed in different directions.
Refractive force in the cornea in different placesdifferent, therefore, when the light rays pass through such a cornea, a distorted image is obtained. Part of the image can focus on the retina, part - before or behind it. The final image that a person sees becomes blurred, distorted.
To make it easier to imagine what it looks likeimage with astigmatism, you can look at your reflection in an oval spoon. This is how the distortion occurs. And how to treat astigmatism, we will consider later.
To learn how to treat astigmatism of the eye, the first thing you need to know is the causes of this disease.
So, the main reason for the occurrence of astigmatismIs the deformation of the lens or cornea. In this case, the cornea does not have the shape of a sphere, but looks like a melon, that is, slightly convex on one side. Light rays, passing through such a curved cornea, focus on the retina at several points (and should be in one). Therefore, the image becomes fuzzy.
In addition, astigmatism can occur against the background of myopia or hyperopia.
Before learning how to treat astigmatism in adults, it is important to know the signs of the disease so as not to make a mistake in choosing a cure.
Most often, astigmatism is inherited. Therefore, its signs can be identified even in childhood. Children can complain about eye fatigue, they can constantly blink, which indicates a decrease in vision, with a load of eyes blush. If parents notice these signs from their child, then it is necessary to urgently show it to the doctor to learn how to treat astigmatism in children.
In addition, children should bedoctor, if such a disease is at least one of the parents. If the child's astigmatism is left without treatment, then there is a risk of reducing vision, which can not be corrected, that is, the development of amblyopia. Therefore, it is extremely important to check the eyesight of the child in a timely manner from a doctor who, in case of disease detection, will give clear recommendations on how to treat astigmatism in children's eyes.
Among the other signs of the disease can be identified the following:
There are three periods of astigmatism - a weak,middle, high. In case of a weak period, eye damage occurs to no more than one diopter. In this case, vision is practically not deteriorated and treatment is not required. With an average and a high period, doctors' intervention is already necessary.
Myopia and hyperopia are the true companions of astigmatism. As a rule, along with astigmatism, there is one thing, but sometimes there are signs of both diseases.
Many people ask themselves: "How to treat astigmatism?" But the treatment is selected by a professional ophthalmologist individually for each patient, based on the type of disease. The disease is divided into species, based on the presence of myopia or farsightedness in one or two main meridians of the eye.
So, astigmatism is of the following types:
In order to know how to treat astigmatism,in addition to its type, it is necessary to determine the degree. For this purpose, in the ophthalmology, the Tabo scale (from 0 to 180 degrees) is used, with which the main axes of the disease are determined.
So, astigmatism is of three types:
And, finally, another important criterion to be considered before deciding how to treat astigmatism is the degree of the disease.
So, ophthalmologists distinguish three main degrees of astigmatism:
It becomes clear that the higher the degreedisease, the more deteriorated vision, and the more difficult it is to fix it. Many people want to learn how to treat astigmatism at home. Consider these and other methods of treatment a little lower.
Many people who notice firstsigns of astigmatism, do not rush to the doctor. And very vain. Absence of treatment can lead to frequent headaches and cuts in the eyes. Childish astigmatism is especially dangerous. Without qualitative treatment, a child may develop strabismus and sharply fall eyesight. Many parents are trying to learn how to treat astigmatism in children at home. There are some tips for treating this disease at home. But the benefit from them will be only if carried out in conjunction with quality medical treatment.
Of course, it is easier to prevent the disease than to treat it. But people forget or simply neglect all methods of preventing diseases until it touches them personally.
Prevention of astigmatism is very simple, it does not take much time and effort, but will preserve health for many years.
So, in order to avoid such a disease as astigmatism, it's enough to simply alternate work with a big load on the eyes with rest.
Very carefully choose the lightingworkplace. It is better to place the lamp in front or to the left of the person. Lighting in the room should be 100%, because when the view is transferred from the lighter part of the room to the darker one, the eyes get tired faster.
These simple tips will help keep your eyesight for many years to come.
For ocular correction of astigmatism, ophthalmologistsappoint special "difficult" glasses. They insert cylindrical lenses. If the patient has a high degree of disease, wearing such glasses can cause him discomfort (dizziness, pain in the eyes). To avoid this, it is important to conduct a thorough diagnosis in order to properly select the necessary glasses. Unfortunately, it often happens that patients have to change glasses several times to get rid of discomfort.
For a long time it was thought that treating astigmatismit is possible only with the use of rigid contact lenses. But they were very uncomfortable in the process of wearing and very badly affected the cornea. However, medicine and science do not stand still, and today more convenient and safe toric lenses are used to correct astigmatism.
So, how to treat astigmatism in adults at home? There are several simple recipes.
