How to prevent worsening astigmatism

Nowadays, many people have increasingly serious myopia problems due to incorrect eye habits and frequent use of electronic products. One of these problems is astigmatism. The main reason is that the retina of the eye is bent, so the light that makes up the image cannot be focused inside the eye, resulting in the problem of double vision. This is astigmatism. Astigmatism not only makes it difficult for people to see clearly, but it also causes great harm to the human body.

What are the dangers of astigmatism?

1. Reduced vision

Astigmatism causes decreased vision because light cannot be focused on the retina. The degree of visual impairment is related to factors such as the nature, degree and direction of astigmatism. Higher degrees of astigmatism (over 200 degrees) can even cause amblyopia in children.

2. Visual fatigue

In order to improve their vision, patients with astigmatism often use accommodation to correct themselves, but continuous accommodative tension can easily cause visual fatigue. People with high astigmatism give up on accommodation because their subjective efforts cannot improve their vision, and the symptoms of visual fatigue are not obvious. When the eyes are in a state of continuous fatigue, it is easy to cause eye diseases such as conjunctivitis, eyelid inflammation (sty, blepharitis) and chalazion.

3. Tilting the head and squinting the eyes when looking at things

Because of astigmatism in both eyes, in order to see more clearly, patients with astigmatism often adjust their head position by tilting it, which can usually be restored after wearing glasses for correction. Squinting can improve vision to a certain extent through the pinhole effect and slit effect in physics. Therefore, patients with astigmatism often squint when looking far away. Wearing glasses can correct this bad habit. It should be noted that squinting is not an inherent manifestation of astigmatism, it can also occur in myopic patients.

How to avoid worsening astigmatism

1. Avoid long-term continuous computer operation. Nowadays, many people need to use computers for a long time. Sometimes they use computers to get off work overtime or play games after work. So in life we ​​should pay attention to keeping our eyes rested and avoid irritation to the eyes caused by long-term use of computers. It is best not to use computers after get off work. There should be sufficient light when reading, preferably from the left rear; the reading posture should be correct and the distance should be maintained between 30-40 cm to prevent astigmatism.

2. Adjust the screen spacing position. The recommended distance is 50-70 cm, and the screen should be slightly lower than the eye level by 10-20 cm, with a downward viewing angle of 15-20 degrees. Because the viewpoint and distance can reduce the need for refraction and reduce the chance of eye fatigue.

3. Supplement the nutrients needed by the eyes. In particular, eat more fruits and vegetables, which can protect your eyesight.

4. Don’t use the air conditioner for too long. Prevent air flow from blowing over the seats and place tea near the seats to increase the surrounding humidity.

5. Remember to drink plenty of water. Because water is an important component of the eyes, replenishing water can avoid dry eyes and is also helpful in preventing astigmatism problems from worsening.
