Myopia is a headache, bringing great inconvenience to people's work, study and life. Moreover, the number of modern people suffering from myopia is constantly increasing, and many children are already wearing glasses. This is actually closely related to their daily study habits and eye habits. If you don’t want to be troubled by myopia, you should pay attention to the following matters. Here I will introduce to you how to prevent myopia.

The most important thing about myopia is prevention, because once you have myopia, it is very difficult to cure it. Unless you undergo surgery, the world in your eyes will be blurry if you don’t wear glasses.

1. Pay attention to eye hygiene: do not read in bed, while walking, in a car, or under strong or dim light; keep a distance of one foot (35 cm) when reading or writing, and the light source should have an illumination of 75 meter candlelight, and should be placed in the left front; when watching TV, the distance between people and TV should be 2.5 to 3 meters, and the TV should be slightly below the horizon, usually not more than 1 hour; the time for playing video games should also be strictly limited, usually not more than half an hour.

2. Lack of calcium and chromium in the diet can induce myopia; a high-sugar diet can also cause the eye axis to lengthen. Therefore, it is recommended to eat more coarse rice and whole grains, eat less sweets, reduce fat intake (which can cause calcium deficiency), and reduce the excretion of chromium, which will help prevent myopia. How to prevent myopia? You need to pay attention to the following points:
