(Fighting against New Coronary Pneumonia) Ophthalmologist: It is not necessary to install anti-blue light equipment for electronic products produced by regular manufacturers

  China News Agency, Beijing, May 10 (Reporter Li Yanan) Wei Wenbin, director and chief physician of the Department of Ophthalmology, Beijing Tongren Hospital, said in Beijing on the 10th that in daily life, using electronic products produced by regular manufacturers, there is no need to install anti-blue light equipment. Reducing the use of eyes at close range, paying attention to the posture of the eyes, and increasing outdoor sports are the most important methods for preventing and controlling myopia.

  The joint defense mechanism of the State Council of China held a press conference on the same day, and invited relevant experts to answer media questions on scientific eye use and prevention of myopia.

  "There is currently an over-interpretation of the hazards of blue light in society. Anti-blue light and visual fatigue are not directly related to myopia prevention and control." Wei Wenbin said that blue light is divided into long-wave blue light and short-wave blue light. Only short-wave blue light will affect eye health. However, this requires long-term, high-intensity, uninterrupted irradiation. The electronic products that pass the quality inspection have filtered harmful short-wave blue light, so in daily life, using electronic products produced by regular manufacturers, there is no need to install anti-blue light equipment.

  Wei Wenbin said that the selection of video tools should adhere to the principle of "Never be big but not small". The selection order is projection, TV, computer, tablet, and mobile phone. The use of electronic products should follow the "20-20-20" mantra: after looking at the screen for 20 minutes, look up at a distance of 20 feet (6 meters) for more than 20 seconds. In addition, the ambient light should be suitable. When using electronic products at night, you need to turn on the light and dim the screen brightness to 30%. You can set a green background screensaver wallpaper to relieve eye fatigue.

  Wei Wenbin pointed out that during the epidemic, some "eye-browing" and "eye-twisting" and various eye-movement exercises with eye movements mainly occurred. This kind of exercise is actually the exercise of the extraocular muscles. It is helpful to some children who need to train binocular vision and strabismus. However, they cannot relieve the fatigue of the intraocular muscles, so they cannot slow down the development of myopia and visual fatigue. .

  In terms of drug treatment, Wei Wenbin said that at present, there is no promotion of drugs to improve vision and control the development of myopia in China.

  "In recent years, studies have indeed found that low concentrations of atropine, that is, 0.01% of atropine, can delay the development of children's myopia. However, low concentration of atropine eye drops is not a magic drug." Wei Wenbin said that some children ordered low concentrations The atropine will be afraid of light, unclear things at close range, and allergic reactions to atropine. There are also some children who order 0.01% atropine eye drops, which cannot effectively control the progress of myopia.

  "Reducing the use of eyes at close range, paying attention to the posture of the eyes, and increasing outdoor sports are the most important methods for preventing and controlling myopia." Wei Wenbin said.

  He also pointed out that preschool children should try to reduce the use of electronic products. The time for watching cartoons should not exceed 15 minutes at a time, and the cumulative time per day should not exceed 1 hour.

  "Pre-school children should have stricter requirements for the use of electronic screens than school-age children, ensuring more than 10 hours of adequate sleep, balanced nutrition, not picky eating, not overeating, eating less sugar, eating more fruits and vegetables, and choosing Appropriate sports or games. "Wei Wenbin said. (Finish)
