The latest data from the National Student Health Survey shows that the prevalence of myopia is 22.78% for elementary school students, 55.22% for secondary school students and 70.34% for high school students, with the above figures increasing year by year. What is more alarming is that a survey report says that more than 300,000 people in China have become blind due to high myopia. Myopia not only brings inconvenience to the blind, but also is closely related to employment, work and college entrance exams, so the prevention and treatment of myopia in children and adolescents is a growing concern for students, parents and society. Myopia is a common eye disease, and the causes of myopia are congenital and acquired. Congenital myopia is mainly high myopia of more than 600 degrees and is mostly related to genetic factors. How to prevent myopia? This requires you to pay attention to the following points: a. Do not let your child read and write in the dark or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within one meter; if a 60-watt light bulb is used, the distance between the book and the bulb should be between one meter and two meters. Cloudy days, dusk, weak light in the moonlight and strong light in the sun are not suitable for reading and writing. Second, pay attention to the time of eye use. Children’s eyes are not fully developed, the ability to work is low, every half hour to an hour of reading or writing, we should close the eyes to rest a while, or to look at the scene in the distance so that the regulation of vision ciliary muscle to get rest, early recovery from vision fatigue. Some children love to hide in a dark corner to read books, a look is more than half the time, which is very damaging to the eyes, very easy to occur myopia. Third, pay attention to the posture of the eyes. Excessive near reading is the main cause of myopia, so when reading and writing sitting posture should be correct, the height of the table and stool should be appropriate, the distance between the eyes and the book should be about a foot, and every hour or so to rest 10 to 15 minutes, outdoor activities or far away, in order to relieve eye regulation. Fourth, good eye exercises. At present, there are Zhejiang Province Lishui School of Health Li Meihong teacher invented the “Rishengjian eye exercise” effect is better. Five, life should be regular, every day to have enough sleep. Insufficient sleep is one of the causes of myopia, should develop the habit of early to bed and early to rise, 8-6-year-old children sleep 10-12 hours a day, 7-12-year-old children, sleep 9-10 hours a day, the summer noon to insist on a nap. Sixth, actively participate in physical exercise, eat more vegetables and fruits. Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes and make the eyes more resistant. Vegetables contain more vitamin A and D, which have a certain nutritional effect on the eyes. Seven, watch less television less play computer. Television is a direct light source, the stimulating effect on the eyes is greater. Children are not suitable for watching TV for a long time (not more than two hours) Teenagers found vision loss how to do? Many people casually go to optical stores to get glasses for convenience, not knowing that this will likely cause serious damage to the child’s eyes! We have found many cases of children with 300-400 degrees of glasses at the optician’s store, but at our hospital, there is no obvious degree of myopia or only 50 degrees of myopia, if they continue to wear the original glasses, the child will become true myopia, and the degree of myopia will rapidly increase! Because such glasses will make the child use more adjustment when looking close. Therefore, if you find that your child’s vision is declining, first go to the hospital for an examination to determine whether it is pseudomyopia or true myopia, do not be casual! In terms of treatment, if it is pseudomyopia, the child should pay attention to proper writing posture, proper rest (for the eyes) and relaxing eye drops (available in hospitals), but if it is true myopia, then glasses are the only option. So is there a way to alleviate myopia deepening? The National Eye Care Project recommends the Golden Sight Keda compound myopia prevention mirror is a good choice, its principle is to reduce the burden on the eyes when looking at the near, while taking into account the ratio of regulation – collection, with the RISO health eye exercises can better treat pseudomyopia and prevent the degree of deepening.
