With the development of society and economy, people’s awareness of health care is gradually strengthening, and eye care is also gaining attention. However, in the children’s group, due to the young age, eye symptoms are not easy to express and often ignored, and parents are too busy to understand their children’s eye condition, resulting in the “glasses family” gradually younger and younger, a considerable part of kindergarten children also wear glasses. According to the relevant reports, the incidence of myopia among elementary school students is 22.78%, 55.22% for secondary school students, 70.34% for high school students, and the myopia rate of the elementary school graduation class with vision below 1.0 is as high as 40% to 50%; and the incidence of myopia is on the rise (urban incidence is higher than rural incidence). For the concept of amblyopia, people often have a vague understanding, thinking that amblyopia is myopia or farsightedness, but in fact, the medical definition of amblyopia is: where there is no organic lesion of the eye, functional factors caused by the main farsightedness ≤ 0.8, and can not be corrected for amblyopia. According to statistics, the prevalence of amblyopia in children in China is 3% to 4%, and according to 300 million children in China, there are more than 9 million children suffering from amblyopia. Amblyopia, strabismus, ocular trauma and other eye diseases affect the normal development of children’s eyes, which can bring physical and psychological trauma to growing children and also cause irreparable damage to families and society. Therefore, children’s eye health care should attract the attention of health departments at all levels, maternal and child health institutions, education departments, parents, families and the whole society. So how to do a good job of children’s eye care? (1) The earlier eye care for children, the better. (1) Strictly speaking, children’s eye health care starts from the mother’s pregnancy, because the formation of the eye begins in the third week of pregnancy, such as intrauterine infection, hypertension or vitamin A deficiency, rubella and poor living habits of pregnant women can affect the formation and development of the fetal eye, causing abnormal fetal eye development. ②Giving appropriate light stimulation during the neonatal period is beneficial to newborn vision development. 2 months give the child the opportunity to track vision, such as: teasing the child with red objects. 4 to 5 months give multi-color stimulation to enhance the coordinated movement of both eyes. 7 to 9 months children look at the action requires visual participation, so give the child more than 2 objects to play with in order to promote visual development. ③ At 1.5 years old, children can read books and recognize simple shapes such as squares and triangles; at about 3 years old, they can recognize ellipses and rhombuses. If the child has obvious visual backwardness, he/she should be examined in time. (2) Pay attention to the balanced intake of nutrients for children, especially those closely related to the eyes: ① Vitamin A: Vitamin A can promote and maintain the growth and normal function of the epithelial tissues of the body, and in the eye, vitamin A can ensure the normal structure of the cornea and participate in the synthesis of retinal retinal rod cell-like substances. Vitamin A deficiency in children can cause corneal dryness, softening and even ulcers. There are two food sources of the vitamin: one is retinol in animal foods, the main foods are: liver, cream, egg yolk, etc.; the second is carotene in plant foods, the main vegetables are: broccoli, carrots, celery leaves, spinach, golden needles, leeks, cantaloupe, pumpkin, etc. Vitamin B 1: Vitamin B 1 deficiency can lead to dry eyes, blurred vision, corneal congestion or increased myopia. Foods containing vitamin B 1 mainly include: cereals (mainly coarse grains), beans, animal liver, etc. Vitamin B 2: When vitamin B 2 is deficient, the eyes may become photophobic, teary, and have a burning sensation, and may cause conjunctivitis. Foods containing vitamin B 2 include: milk, egg yolk, liver, soybeans, dark green plant foods, etc. Calcium: The important role of calcium for bone development has long been recognized, but its effect on eye development is often overlooked. In fact, when children are deficient in calcium, the elasticity of the eye wall is reduced and the pressure inside the eye elongates the eye axis, especially when reading books and watching TV at close range, and excessive eye use will contribute to the occurrence of myopia, which is also one of the causes of myopia in children at present. The main foods rich in calcium are: shrimp, sea rice, egg yolk, dried tofu, nori, kelp, tofu, milk, etc. It is important to note that the absorption of calcium requires the participation of vitamin D. Therefore, attention should be paid to the supplementation of vitamin D while supplementing calcium. (3) Families, schools and child care institutions together pay attention to children’s eye examinations: At present, schools and child care institutions have a routine physical examination once a year, including eye examinations, but some families, schools or kindergartens do not pay enough attention to the examination results and do not go for further review, confirmation and correction of the problems found, so that some children’s eye disorders miss the best time for treatment. Therefore, in order to do a good job in children’s eye care, so that children’s visual abnormalities can be corrected during the sensitive period or the best period, parents and educational institutions need to work together and pay joint attention. (4) Maternal and child health care institutions and the general maternal and child health care personnel should increase their publicity efforts to popularize general knowledge of eye health care. (1) Adopt a variety of popular forms to disseminate scientific knowledge, so that people know about eye care and take the initiative to pay attention to children’s eyes. ②Educate children to know how to care for their eyes. For example, they should not watch TV for more than half an hour at a time, they should not read books lying down, they should not read books in bright light; they should read and write in a correct posture, i.e., one foot (eyes one foot from the book), one fist (chest one fist from the table), one inch (index finger one inch from the pen tip). ③Schools and kindergartens should be equipped with standard tables and chairs, and classrooms should be appropriately lit, supplemented by artificial lighting on rainy days. (4) Strengthen outdoor activities and carry out eye exercises. (5) Health departments at all levels, maternal and child health institutions, education departments, and parents of children to achieve early detection and treatment. (1) Although the child’s eye symptoms are not easy to detect, especially those with poor vision in one eye, parents just need to pay attention to see if the child has been rubbing his eyes a lot lately, if he likes to squint when looking at things, if he says his eyes are foggy, etc. These can indicate the child’s eye problems. ②School and kindergarten teachers should pay attention to whether the child often misspells words, becomes quiet, and looks at the blackboard with a tilted head, etc. These can also indicate eye problems in children. Eye problems found should be reviewed, diagnosed and corrected as early as possible, because different visual problems require different methods to solve, such as the correction of myopia and farsightedness is completely different. The best time to correct children’s vision is from 3 to 5 years old, so it is equally important to achieve early detection and early treatment, and not to let our sloppiness leave lifelong pain and regret for our children. In conclusion, in the face of the colorful world and the challenges of high technology, it is of great importance to do a good job in children’s eye care. It needs the high attention of health departments at all levels, maternal and child health institutions, education departments, parents of children, families and the whole society.
