Astigmatism refers to the refractive error of the eye, which is closely related to the curvature of the human cornea. Astigmatism brings a lot of trouble to people. The most obvious feeling is the inability to see fast-moving objects. There are many reasons for astigmatism, including congenital reasons and acquired reasons. For example, if you have styes and don’t get good treatment, it may lead to acquired astigmatism. What causes flashing eyes? Regular astigmatism is mostly caused by congenital abnormal changes in the cornea, and some patients may also have lens astigmatism. There are also some astigmatism caused by acquired factors, such as styes or milia on the eyelids, and long-term poor eye posture (such as frequent squinting, rubbing eyes, reading while lying down, etc.). The pressure of the eyelids on the cornea will also change the curvature of the cornea, causing astigmatism and increasing the degree of astigmatism. In addition, certain eye surgeries, such as cataract and corneal surgery, may also change the degree and axis of astigmatism. Prevention of astigmatism 1. Observe carefully and take the patient to an eye hospital for examination if any problem is found. 2. Have regular eye examinations 1-2 times a year. 3. Guide young children to recognize dangerous games and toys to reduce eye injuries. 4. Guide young children to develop good hygiene habits and avoid touching their eyes with their hands or other items to avoid contracting eye diseases. If they are infected with eye diseases, try to reduce going out. 5. There should be sufficient light when reading, and it is best if the light comes from the left rear; the reading posture should be correct and the distance should be maintained between 30 cm and 40 cm. 6. Don’t read in a shaking car or while lying down. 7. When choosing reading materials, the font should be clear and not too small. 8. Place the TV slightly below eye level, and watch TV at a distance 5-7 times the diagonal of the TV screen. 9. Do not read continuously for more than one hour. Take a 5-minute break every 30 minutes. |
