Stare at the computer for 20 seconds and don't forget to blink.

Modern people have to interact with computers for work or leisure life, and even spend 10 days staring at computers for 10 hours. In the long run, it is not only easy to cause eye fatigue and acidity, but also may have a negative impact on vision. Researchers at Southwest Medical Center recently put forward a set of "20-20-20-20" eye protection formula, which blinks every 20 minutes when watching a computer.

Many people usually use the computer for more than three hours a day, which is easy to cause eye pain and discomfort. (Photo/Huang Zhiwen) The British "Daily Mail" reported that the "20-20-20-20" eye care formula proposed by Edward Mendelson, a professor at the Southwest Medical Center of the University of Texas in the United States, is mainly aimed at the eye discomfort caused by the "computer vision syndrome" that modern people often suffer from, and even

Professor Edward pointed out that staring at the computer often reduces the number of blinks, making the eyes not secrete enough tears and become dry. Therefore, it is best to leave the computer screen for 20 seconds and blink for 20 seconds every 20 minutes to make your eyes naturally moist; And the distance is about 20 feet (about 6 meters).

The research professor also pointed out that sedentary office workers are more prone to eye fatigue, dry and cold indoors, and uncomfortable eyes. Therefore, they should pay more attention to eye care, and because "computer vision syndrome" also includes shoulder and neck pain, headache and other phenomena, it is also a better choice to exercise for more than 1 minute than simply dropping eye drops.
