The key of eye exercises is to alleviate visual fatigue

Abstract: eye exercises are beneficial in alleviating visual fatigue. After about 40 minutes of eye activities, closing your eyes and doing eye exercises can rest your eyes, and acupoint massage can also relax the muscles around your eyes.

eye exercises are the collective memories of several generations of Chinese people. With their beautiful youth, few people think about its value and significance. However, the recent microblog of “eye exercises have harmed Chinese teenagers for 49 years” sent by a netizen has put eye exercises on the cusp of the storm. Is the effect of eye exercises on eyes good or bad? Let’s invite Professor LAN Yuqing, director of Ophthalmology of Sun Yat Sen Memorial Hospital of Sun Yat sen University, to comment. Benefits of

said that in the past few decades, the country has forcibly promoted eye exercises to prevent juvenile myopia, which exaggerates the role of eye exercises. But saying that it “harmed teenagers” is also too sensational. The causes of myopia are very complex, which are related to the environment, diet, genes, eye hygiene, eye habits, etc. the current medicine has not fully understood the causes of myopia, let alone found an accurate way to prevent myopia. Therefore, to say that eye exercises can prevent and treat myopia, doctors have not obtained evidence-based medicine to prove that eye exercises have an impact on myopia.

however, eye exercises do have benefits in alleviating visual fatigue. After about 40 minutes of eye activities, closing your eyes and doing eye exercises can rest your eyes, and acupoint massage can also relax the muscles around your eyes. Just as massage can relieve back pain, serious eye exercises can also make your eyes feel relaxed and comfortable. Disadvantages of

. Fang Zhouzi, an anti-counterfeiting expert, said in the article, “(eye exercises) often touch and rub the eyes with unclean hands, which increases the risk of eye infection and even respiratory tract infection (the virus will enter the upper respiratory tract from the nasolacrimal duct)” , is that really the case? Director LAN Yuqing said that the risk mentioned by Fang Zhouzi is tenable in theory, but clinically, no children with red eye disease and other diseases caused by eye exercises have been found. Moreover, in order to avoid such risks, the new version of eye exercises has changed the past action of “dry washing face” to “pressing the Du meridian point on the head”. Until today, clinicians have not observed the side effects of eye exercises.

to prevent myopia: it also depends on the correct use of eyes.

director LAN Yuqing said that if teenagers want to prevent myopia, correct eye hygiene is very important. The main points are as follows:

1 The time for close eye use should not be too long. Rest for 10 ~ 15 minutes every 40-45 minutes. When resting, you should look out through the window or carry out outdoor activities to fully relax your ciliary muscles.

  2. In the night or dark environment, it is best to use 40 ~ 60W incandescent lamp for lighting and put it in the upper left corner of the desk to prevent eye fatigue caused by too strong or too dark light.

  3. When using the eyes at close range, the height ratio of tables and chairs shall be appropriate, the back shall be straight, and the books shall be placed 30cm away from the eyes. Bad eye habits such as reading by car, lying in bed or reading with crooked head will increase the burden of eye regulation and the pressure of extraocular muscles on the eyeball.

  4. Actively participate in physical exercise and enhance physical fitness. No partial eclipse, no picky eaters, and ensure balanced nutrition.
