Recognized Astigmatism
Astigmatism is a common eye disease that causes a person to lose the ability to see clearly. Translated from Latin, the term means “the absence of a focal point”. If left untreated, it can lead to strabismus and a sharp drop in vision.

Fortunately, astigmatism is quite easy to detect. This can be done even at home. In order to detect the defect in time and preserve vision, "Site" He asks you to take three simple tests.
Correction of astigmatism Astigmatism occurs due to the irregular (not spherical) shape of the cornea (less often - the lens). In normal condition, the cornea and lens of a healthy eye have a flat spherical surface. With astigmatism, their sphericality is disturbed. It has different curvature in different directions.

Astigmatism is often diagnosed in early school or preschool age. Children with astigmatism may confuse similar numbers and letters, change them in words in places. The child has complaints of fuzzyness, distortion of vision. The presence of astigmatism may also indicate other symptoms.
Astigmatism symptoms
Without correction, astigmatism will progress and lead to serious complications. The following methods of correction of this violation are most often used.
What helps with astigmatism
There are some of the most popular tests for astigmatism. They will help you know if you have the disease or not. And when it is detected, it is necessary to start treatment in a timely manner.
Take this issue seriously, take each test several times to make sure the results are for sure.
Divergent ray test
An important factor when passing this test is bright daylight.
Siemens star
This test is considered one of the most accurate and correct. The image of the so-called Siemens star has lines equal to each other in all respects. They are also moving in the same direction.
If a person with one hundred percent vision considers the above picture from five meters, then the rays begin to merge exactly at half of their length, that is, when 2.5 cm remains to the center (with a full beam length of 5.0 cm).
Look at the rays of the Siemens star alternately with each eye. If there are no violations, your eyes will see the following.
Astigmatism testing using these tests is approximate and can not accurately indicate the presence of the disease. But it can make it clear that you should consult an ophthalmologist who, after a clinical examination, will make an accurate diagnosis.
Frequent headaches, fatigue, fatigue, burning in the eyes are symptoms that are familiar to almost all people. You may be surprised, but often to get rid of these troubles, you just need to go to the ophthalmologist.
Today's edition. "Site" He will tell you why even people with 100% vision should wear anti-reflective glasses, and occasionally visit an optometrist and measure eye pressure.
To restore vision without surgery will help gymnastics for vision according to Norbekov. Thanks to this method, thousands of people have forgotten about glasses forever.

Astigmatism symptoms
- The feeling of “sand” and burning in the eyes.
- Eye redness.
DepositPhotos - Duplication and distortion of visual images.
- Inability to focus your eyes.
- Difficulties with orientation in space, determining the distance to objects.
- Fast eye fatigue with such visual work as reading, watching TV, working at the computer.
DepositPhotos - Pain in the area of the eyebrow arches, frequent headaches.
Without correction, astigmatism will progress and lead to serious complications. The following methods of correction of this violation are most often used.
What helps with astigmatism
- Points.
The most common method of correction. With astigmatism, glasses are selected individually with a combination of spherical and cylindrical lenses.
DepositPhotos - Contact lenses
Very convenient to use, because they form a single optical system with the eye and do not cause distortion.
DepositPhotos - Laser correction
The safest and most effective method Low and medium. Laser correction improves vision and eliminates the need to wear glasses and contact lenses.
- Surgical intervention
If the correction of astigmatism by optical means is impossible, an operation - keratotomy can be shown. Then the eyes of the eye are turned to the surface of the cornea, which then grow. The ancestor of the method was in the thirties of the last century, the Japanese ophthalmologist Tsumotu-Sato. New life in this method was breathed by the famous Soviet ophthalmic surgeon Svyatoslav Fedorov. He used new diamond tools and microscopes to take operations to a new level.

Divergent ray test
- Close one eye, step 3-5 steps away from the monitor and look at the circle.
- Notice if some of the lines get darker than others.
- If so, you may have astigmatism.
An important factor when passing this test is bright daylight.
- Close one eye and then the other.
- If you see all the lines equally black, you probably don’t have astigmatism.
- If you don’t see all the lines in the squares in the same black, if one or more squares look gray, then you have astigmatism.

Look at the rays of the Siemens star alternately with each eye. If there are no violations, your eyes will see the following.
- The vagueness of clear lines.
- The background will become gray in the center of this star.
- The central lines will gradually merge into a circle.
