What are the methods to prevent myopia

Myopia is a very common eye disease. It has a great impact on people's lives. In the eyes of myopic people, the world is blurry, unless they wear glasses. However, wearing glasses is very troublesome. They need to be pushed by hands from time to time, and it also affects the appearance. However, more and more people suffer from myopia nowadays. What is the reason? How can we not be troubled by myopia? What are the ways to prevent myopia?

Eye diseases like myopia must be prevented, and the prevention should start from childhood. Because the modern population suffering from myopia is getting younger and younger, if children do not pay attention to the correct reading posture or use their eyes unhealthily when they are young, they may develop myopia.

1. Do not use your eyes at close range for too long. Take a 10-15 minute break every 45-60 minutes. Look into the distance when you rest.

2. The light should be moderate when using your eyes at close range. Because in most cases, decreased vision is related to poor lighting, especially when the ambient light intensity is inappropriate in study, work and life where the eyes are used intensively. Sometimes the light is too dim, and sometimes it is too bright.

3. To prevent myopia, you should maintain the correct eye posture when using eyes at close range. Close eye posture is another factor that affects the incidence of myopia. When using your eyes at close range, the height ratio of the table and chair should be appropriate. Sit upright and place the book 30 cm away from your eyes. Bad eye habits such as reading in a car, reading in bed, or reading with the head tilted at a desk will increase the eye's accommodation burden and convergence frequency, and increase the pressure of the extraocular muscles on the eyeball. This is especially true for primary and secondary school students whose eyeballs are in the development stage and the wall of the eyeball is relatively stretchable. Long-term bad eye postures can easily cause abnormal development of the eyeball and lead to the formation of myopia.

4. There is high-energy short-wave blue light in the LED screens of computers, televisions, and 3D digital products. Blue light is a high-energy, highly penetrating visible light that can penetrate the lens directly to the retina, causing photochemical damage to humans. In daily life, in addition to flash lights, this blue light also exists in sunlight.

From the above introduction, we can see that there are many ways to prevent myopia, so everyone must pay attention to their posture when studying, keep a distance from the TV when watching TV and pay attention to the light not being too dim. If you unfortunately still suffer from myopia, you need to correct it in time and protect your eyes well to prevent the degree from increasing.
