Abstract: at present, the most common “myopia” problem of children has not been paid attention to by parents. Improper prevention in the early stage will make children’s “myopia” more serious. Teenagers are in a period of physical growth and development, and their eyeballs are also growing and developing. Therefore, paying attention to developing good eye habits from childhood can effectively prevent the occurrence of myopia., “The eye is the window of the soul”, but if the line of sight becomes blurred, the beautiful world will also become eclipsed. In recent years, the prevalence of myopia in adolescents has increased, and with the increase of grade, the prevalence of myopia is also increasing., Juvenile myopia generally starts from pseudomyopia. At present, the most common “myopia” problem of children has not been paid attention to by parents. Improper prevention in the early stage will make children’s “myopia” more serious. It is understood that the incidence rate of juvenile myopia in China is as high as 50% to 60%. The rising rate of myopia has become an important factor affecting the health of adolescents. Experts pointed out that a large number of children are not true myopia, but only pseudomyopia. If they do not pay attention to eye health care, they may change from pseudomyopia to true myopia., Juvenile myopia generally starts from pseudomyopia. Pseudomyopia is due to long-term close use of the eye, excessive tension of the ciliary muscle, resulting in ciliary muscle spasm, lens thickening and convex. Even when looking at distant objects, it continues to maintain tension regulation, the lens cannot restore its original thickness, and even the object image is blurred. Therefore, teenagers should learn to control eye time and adhere to eye exercises. In addition, parents should always pay attention to the changes of their children’s vision, be alert to the occurrence of pseudomyopia, and seek medical treatment in time once it occurs., Myopia without glasses has “degree”, and

Pseudomyopia is due to long-term close use of the eye, excessive tension of the ciliary muscle, resulting in ciliary muscle spasm, lens thickening and convex.

myopia without glasses is a “degree”. The

and “small glasses” are increasing. Some parents feel that their children are small and do not need to be corrected in a hurry. They can wear them when they grow up. But experts point out that myopia without glasses is actually “degree”. If it exceeds a critical boundary, it will have a lifelong impact on children. Experts say that from the perspective of eye hygiene, it is generally unnecessary to wear glasses for mild myopia below 100 degrees, but the premise is that the eyes are not tired when looking at the blackboard. Mild myopia below 300 degrees can not wear glasses to see near objects. Glasses should be worn when watching blackboard and TV. Glasses should be worn when myopia reaches a certain degree.
some students and parents worry that wearing glasses will make the degree deeper and deeper, while others are afraid that once they wear glasses, they will not be able to take them off. In fact, this concern is groundless. Wearing frame glasses is the most effective way to correct ametropia.
in addition, some students like to wear contact lenses, but experts say that wearing contact lenses for a long time will make the cornea in a state of hypoxia, cause neovascularization in surrounding tissues, and easily cause corneal abrasion and infection. Therefore, it is suggested that contact lenses should not be worn or less, and the wearing time should not exceed 10 hours a day.
good eye habits can prevent myopia.
good living habits and reasonable eye use can prevent juvenile myopia. Experts suggest:
reasonable diet. In terms of physical health, what is needed is nutrition, what is lacking is in urgent need of supplement, and what is surplus is harmful. Therefore, don’t let children be picky and partial eaters. The types of food should be as rich as possible. Eat meat and vegetables together. Don’t let the physiological development of the eyes “in short supply”. The material form of the food itself should be natural.
moderate exercise. After a long time of sitting still with your eyes, your eyes will be tired and feel sour and painful. At this time, it is most necessary to get up and exercise, preferably outdoor aerobic exercise, to promote systemic blood circulation and accelerate the decomposition of fatigue metabolites. Primary and secondary school students can protect their eyesight and health by doing sports activities for 10 ~ 30 minutes after finishing their homework in the evening.
keep a good mental state. Many children’s myopia occurs in the tense stage of learning, while parents often mistakenly think that they have “used” their eyes after reading for a long time. In fact, the negative impact of mental stress on vision is much more than the impact of eye time. When people are nervous, their muscles are stiff, aggravating the degree of fatigue, which is not conducive to the decomposition of fatigue metabolites, resulting in a high incidence of myopia. Timely intersperse rest activities to eliminate mental tension. Visual fatigue can be recovered.
avoid using eyes under strong light for a long time. Many parents feel that strong light is good for their eyes, and even install a 100 watt bulb on the table lamp, which will aggravate eye fatigue. Because the light intensity has a direct impact on pupil dilation, too strong light will increase the eye adjustment intensity and aggravate the labor intensity of the eyes. It is easy to cause myopia after a long time. Generally, the desk lamp should be less than 40 watts.
