“Care for vision and light up” — to prevent myopia, let children have more outdoor activities

Abstract: therefore, the volunteer service team of Zhongshan eye center of Sun Yat sen University came to Xiangyang primary school in Baiyun District of Guangzhou to carry out free vision examination by means of the activity of “learning from Lei Feng and building a new wind”.

children’s vision problem has attracted much attention, especially the proportion of students wearing glasses is increasing year by year. Zhongshan Eye Center has conducted a sampling survey on the vision status of children in Guangdong Province. It is found that 70% of children aged 5 ~ 15 have different degrees of myopia, and 95% of children’s vision defects are caused by ametropia. Although scientific glasses can safely and effectively correct myopia, the survey shows that only 1 / 3 of children with visual impairment wear formal prescription glasses, while the other 2 / 3 of children have never received optometry glasses service or wear wrong glasses.

to this end, the volunteer service team of Sun Yat Sen eye center of Sun Yat sen University came to Xiangyang primary school in Baiyun District of Guangzhou to carry out free vision examination through the activity of “learning from Lei Feng and building a new wind”. Chen Linxing, an expert of Sun Yat Sen eye center of Sun Yat sen University, said that since 98% of the primary school students in Xiangyang primary school are children of migrant workers, many students have never had vision examination, So this time I came to the school to help these children. Primary school students should pay attention to myopia, astigmatism and congenital eye diseases. “This activity is still very meaningful. When we checked just now, we found that a little girl with more than 300 degrees of myopia has never worn glasses or had her eyesight checked.” Dr. Chen said that this activity is mainly to help primary school students carry out vision examination, ocular surface examination, medical optometry, eye health consultation and give ophthalmic drugs, because most of the vision problems in primary school students are myopia, astigmatism and congenital eye diseases. Prevention of myopia should increase children’s outdoor activities. Thirty percent of the students in Grade 5 have myopia problems, and they reach the peak in Grade 6. More than half of the students have myopia problems. The reason why there is such a high proportion, Dr. Chen said, is closely related to the lack of outdoor activities in the sun. In the eyes of ophthalmologists, the increasing rate of students’ abnormal vision year by year is that the eyes of school-age children have been adaptive to long-term and close eye use. “If you watch closely for a long time, you will have fewer opportunities to see far, and myopia will worsen.” Chen Linxing believes that the lack of outdoor activities can not only hurt the body, but also the eyes. “We need outdoor observation in life, especially children who are in the stage of growth and development.” He introduced that generally, the diopter of the eyes under the age of 18 is still unstable, the chance of far vision is reduced, and the distance adjustment of the ocular axis is lack, which is easy to cause the growth of the ocular axis. The decrease of telephoto opportunity is more likely to cause the growth of ocular axis. It is reported that myopia will increase by 300 ° for every 1mm increase in the ocular axis. The principle of paying attention to the combination of work and rest is well known, but few people really practice it. Chen Linxing reminded that under the pressure of heavy schoolwork, school-age children need the guidance of their parents to help their children increase opportunities for outdoor activities and adjust their eye use. If parents blindly aspire to their children’s success and ignore the relaxation of children’s eyes for a long time, children are prone to vision problems. In addition, Dr. Chen mentioned that astigmatism is also common among primary and secondary school students, which often occurs at the same time as myopia. If parents do not pay attention to it, it will lead to double shadows in children’s images. For congenital eye diseases, Dr. Chen suggested that school-age children need visual examination before entering school. For some eye diseases, only early detection and early intervention can recover. Extended reading: Children’s visual care action is supported by Helen Keller foundation and Mike Susan Dale foundation, an international non-governmental public welfare organization, and initiated by Zhongshan eye center of Sun Yat sen University. As the problem of juvenile myopia is becoming more and more serious, it has aroused great concern from the government, education departments and all sectors of society. It is urgent to curb the increasing trend of myopia prevalence year by year. “Children’s vision care action”, also known as Guangzhou school-age children’s vision health care and glasses gift project, aims to provide free ophthalmic medical assistance for ametropic children from urban low-income families. Zhongshan eye center of Sun Yat sen University has formulated the project plan of “children’s visual care action”. The first phase of the project will be carried out for two years, first in Liwan District and Baiyun District of Guangzhou, targeting school students aged 7 to 15. We will provide scientific eye care education and services for parents, teachers and students, provide standardized medical optometry for 50000 school children, provide qualified prescription glasses for about 10000 children in need free of charge, and help schools train eye care teachers.
