Chinanews.com, Shanghai, March 15 (Reporter Chen Jing) Currently, primary and secondary schools in Shanghai are carrying out online teaching. Adolescent myopia prevention and control has become a topic of concern for parents.
Yang Yong, director of the Optometry and Pediatric Ophthalmology Department of Shanghai Aier Eye Hospital, said on the 15th that children should be guaranteed 8 hours of adequate sleep, because lack of sleep may affect children’s health through endocrine, neurological, immune and other ways. Eye development; at the same time, daily “bathing” in the sun for two hours can effectively prevent myopia.
He proposed the “20-20-20” formula to the students in the online class, that is: after watching the online class for 20 minutes, look up and look at least 20 feet (6 meters away) away. Relax for more than 20 seconds (go to the kitchen, balcony, living room, etc. to look into the distance and relax). He advises children to arrange activities on the balcony or in their yard as much as possible during the midday hours.
In terms of diet, Yang Yong pointed out that sufficient and comprehensive nutrient intake can keep the eyes healthy. Vitamin A, Vitamin C, Vitamin E, omega-3 fatty acids, lutein, zeaxanthin, mineral zinc can protect children’s eyes. Children should eat more fruits and vegetables. Some children especially like to eat chocolate, candy, etc., parents must control.
Unreasonable eye habits and eye environment are the real culprits that lead to the deepening of myopia. In an interview, the expert emphasized the reasonable control of eye time to reduce eye discomfort. In addition to ensuring correct reading and writing posture, Yang Yong pointed out that qualified families can prefer devices with larger screens such as projectors or TVs, and the children’s viewing distance is not less than 4 times the diagonal of the screen. He said that large screen sizes such as projectors and TVs can better protect eyes for long-distance viewing. (End)
