As summer vacation approaches, major hospitals are experiencing a peak of medical attention, and there are also many "small patients" flocking to the ophthalmology clinics for treatment. According to data from the National Health Commission, the overall myopia rate among children and adolescents in China reached 52.7% in 2020, an increase of 2.5 percentage points compared to 2019. As the saying goes, the eyes are the window of the soul, and improper eye habits can lead to eye diseases such as myopia. Anxiety about a child's visual health may be a challenge that every parent encounters. So, what should parents do to overcome the dilemma of "myopia anxiety"? Due to factors such as electronic products, myopia continues to develop at a younger age. With the arrival of summer, many parents choose to take their children to the hospital's ophthalmology clinic to check their eye vision. According to a staff member from the outpatient department of Beijing Tongren Hospital, the number of outpatient patients in the hospital has increased significantly since the beginning of summer, and there is a clear trend towards younger patients. Eighty percent of the patients who come for treatment are true myopia. This also makes many parents confused, how can a child become nearsighted at such a young age? Experts said that at present, among the children with Refractive error in the outpatient clinic, children aged two or three years or even more than one year old have been diagnosed as myopia. This part of children is mainly affected by congenital heredity. Children aged three to six are mainly amblyopia, while those aged seven to 12 are mostly myopia. Among them, there are more and more children with myopia before the age of eight. Myopia is developing at a younger age, mainly because parents do not pay attention to the cultivation of children's eye habits Electronic products and other related factors lead to frequent eye contact at close range. Nowadays, children have less outdoor activities, coupled with less sleep when using electronic products and mobile phones at any time, which is increasingly affecting their vision. Lu Hai, Director of the Pediatric Fundus Department at Beijing Tongren Hospital: When our eyes are looking at objects or people, the light passing through the set of optical systems in front of us should clearly fall on our retina, or more accurately on the macula, in order to have a clear image, which is considered a clear object or a clear scene that our human eyes can see. Teenagers are more accommodative myopia, that is, after the light passes through our cornea and lens, and after our Ciliary muscle is over regulated, the image is imaged in front of our retina, and the image cannot be accurately focused on our retina and macula, causing the image we see to be blurred. Another situation is due to certain pathological factors, such as congenital genetic abnormalities in the child, or high myopia in the parents. This genetic factor causes the eye axis to become longer than that of a normal child, which can also cause us to see images falling in front of the retina. Medical staff emphasize that after the baby is born, it is recommended to avoid contact with electronic products within the age of 2. Regular child health care includes vision screening. Starting from the age of 3, parents can take their child to undergo systematic eye examinations and establish a vision development record. Research has found that exposure to sunlight is an effective measure to prevent myopia, and outdoor activities can help reduce the deepening of myopia. It is recommended that primary and secondary school students engage in outdoor activities for at least 2 hours a day and at least 14 hours a week, which can effectively prevent myopia. How to determine if a child needs dilated pupils for optometry? When a child's vision is found to be unsatisfactory or may be nearsighted, doctors sometimes suggest that the child dilate their pupils to confirm whether it is true myopia. So, how to judge the child
