A one-year-old baby was admitted to the eye clinic of a hospital in Huai 'an, Jiangsu. After the instrument inspection, parents were shocked when they got the inspection report. Their one-year-old child is already nearsighted 100 degrees. After communicating with the doctor, I found that it was because parents showed their children early education videos every day. Ophthalmologists also said that children before the age of two should not touch any electronic products, and any TV, mobile phone and computer belong to electronic products. After two years old, we should control the time of daily contact with electronic products. In life, many manufacturers will design toys with sound and light in order to attract children's love. Ophthalmologists also said that this kind of flash will also have an impact on children's eyes, and parents are advised not to buy this kind of toy. Don't show any electronic products until the child is two years old. After the child is two years old, it is necessary to limit the time that the child watches every day, usually within half an hour every day. According to the results of the eyesight survey from the Ministry of Education, the myopia rate of middle school students increased by 1 1.7% in the same period last year. The number of primary school students has also increased compared with last year, reaching 15%. According to the staff of Nanjing Medical University, due to the epidemic in 2020, many children have no time for outdoor activities and spend too much time using electronic products at home. Only in recent months, students' myopia has been particularly high, and serious children have even grown to 100 degrees. For parents, it is necessary to control their children's contact time with electronic products in life, and let their children be outdoors for more than 1 hour every day. It is recommended to use large-screen electronic products to watch more than three meters. Don't let children overuse their eyes, give them more time to rest and check their eyes regularly. Ophthalmologists say that in addition to controlling the time children spend using electronic products, they can also let their children stare at a place 20 feet away from them for 20 seconds after watching the video for 20 minutes. This method can effectively prevent children's myopia.
