With astigmatism, a person sees objects distorted, blurred, both near and away. There are methods of correction of astigmatism, but it is possible to completely get rid of astigmatism using a surgical operation.

Astigmatism - what it is
Astigmatism is the pathology of the refraction of the eye at which the sphericality of the cornea is disturbed,.E. In different meridians, the different refractive force and the image of the subject when the light rays passes through such a cornea is not obtained in the form of a point, but in the form of a stretch. The person sees the items distorted, in which the lines are clear, others - blurred. Congenital astigmatism up to 0.5 diopters occurs in most people and belongs to «Functional», which practically does not affect visual sharpness. However, as practice shows, astigmatism is already in 1 diopter and more reduces eyesight and worsens visual comfort. Such a kind of pathology is detected in approximately 10% of the case among 25% of children with all kinds of amitropium. Such patients with astigmatism requires early vision correction with the help of cylindrical (spherocylindrical) glasses. This is the main prevention of amblyopia, squinting and visual discomfort.
Astigmatism - image of objects distorted, some lines are clear, other blurred.
Astigmatism - causes and timing
The reasons for the occurrence of astigmatism were not fully understood. In most cases, astigmatism is congenital and inherited, detected in childhood. However, the cause of astigmatism can be operations or eye injuries. Image of objects with astigmatism fuzzy, blurred places, straight lines look curved. In addition to the defects of visual perception, astigmatism is usually accompanied by a rapid fatigue, a decrease of vision, headaches.
It is important: If in the family there are patients with astigmatism - the child must be necessarily examined by an ophthalmologist. Astigmatism is detected only with full ophthalmological examination. Sick astigmatism feels only a decrease in visual acuity. To correctly determine the degree of astigmatism and, especially its axes, a thorough computer examination is necessary. Even small errors in diagnostics can lead to complete intolerance of points or lenses, as well as to impairment of sight.
Conservative treatment of astigmatism
Early diagnosis of astigmatism - Complete ophthalmological examination, including computer research of eye axes.
Proper vision correction - Using glasses with special cylindrical lenses or special contact lenses (toric lenses) selected by an ophthalmologist.
Music training - Responsible for the accommodation of the eye (laser stimulation, video compromising correction of vision, injection of drugs, special courses of eye gymnastics) - under the supervision of an ophthalmologist.
Structuring events - swimming, collar zone massage, contrasting shower and t.D. On the recommendation of the ophthalmologist.
Full nutrition - Balanced in protein, vitamins and microelements such as Zn, Mn, Cu, Cr and DR.
Modern methods of astigmatism correction
Currently, there are three recognized methods of correction of astigmatism, namely:
Glasses - the most common method of correction of astigmatism, especially in childhood. Under astigmatism, glasses are used with special cylindrical lenses - positive or negative - depending on the type of astigmatism. With all its advantages, glasses deliver to their owner a lot of inconvenience - constantly dumping, fogged, slide and fall, interfere with sports and any other active physical activity. Points do not provide 100% vision correction. Points significantly limit the lateral vision, disturb the stereoscopic effect and spatial perception, which is especially important for drivers. When accidental or drop, broken glass lenses may cause serious injury. In addition, incorrectly selected glasses can cause constant overwork of the eyes and progression of astigmatism. However, glasses today remain the easiest, cheap and safe method of correction of astigmatism.
Contact lenses - Contact lenses are used to correlate astigmatism, a small degree (up to 3 diopters). At astigmatism, special - theory lenses that the ophthalmologist must choose. Toric lenses are characterized by all limitations and inconveniences, as well as other types of contact lenses.
Laser correction of astigmatism - For adults (older than 18 years), with a stable form of astigmatism, modern ophthalmology offers the most progressive method of correction - laser correction of astigmatism. The best laser correction technology with astigmatism today is Lasik - an operation that guarantees patient with astigmatism normal vision, without any restrictions.
Prevention of astigmatism
Lighting mode - visual loads only with good lighting, using top light, table lamp 60-100 W, do not use daylight lamps.
Mode of visual and physical exertion - It is recommended to alternate visual stresses with active, rolling rest.
Gymnastics for eyes - After 20-30 minutes of classes, it is recommended to conduct gymnastics for the eyes.
