How can white-collar workers prevent dry eyes?

  Modern white-collar workers often sit in front of the computer for several hours due to the need to work. From the surface, sitting and working, playing with the computer is very comfortable, but over time they will also encounter a lot of trouble, such as visual fatigue, dry eyes, blurred vision and other eye discomfort symptoms, some also accompanied by finger numbness, shoulder stiffness, arm pain and other physical discomfort, thus affecting the mood, affecting the work.  In fact, this is a disease called “video terminal eye disease” that every white-collar worker may encounter. The disease is mostly favored by white-collar workers, which is inseparable from the environment and nature of their work. Working in front of a computer, with a high level of concentration and a reduced number of blinks, is one of the reasons for the development of this disease.  The blinking process moves the upper and lower eyelids to each other, creating a negative pressure pump effect that drains tears from the tear dots to the nasolacrimal ducts and also removes dust and microorganisms that adhere to the eye surface; it also evenly coats the surface of the cornea with lipids secreted from the eyelids, keeping the cornea moist and allowing it to play its normal physiological optical role.  The decrease in the number of blinks often leads to excessive tear evaporation, shortening the tear film rupture time and affecting the quality of the tear film, resulting in symptoms such as ocular foreign body sensation and dry eyes; prolonged close eye use and prolonged tension in the ciliary muscles that regulate the eye’s close work can cause vision fatigue, sometimes accompanied by headaches.  From the point of view of Chinese medicine, “long vision hurts blood, long lying hurts qi, long sitting hurts flesh ……” (Nei Jing), “the eye gets blood and can see” (Ancient and Modern Medical System Complete Ophthalmology), the eye The reason why the eye can see everything, depends entirely on the blood nourishment and moistening, and the blood can not on its own, depends on the promotion of qi, qi line is blood line, qi stagnation is blood stasis. National medical master Tang Yuzhi has also repeatedly stressed the close relationship between the eye and blood, saying that the eye is the organ of more blood and more gas. For white-collar workers, they use their eyes more and move less. Liver blood, the main drainage; spleen blood, the main muscle, for the day after the origin, the source of blood biochemistry. Long hours of ambulatory work, easy to make the spleen qi damaged, the transformation of qi and blood power lack of source; liver blood collection, regulation of qi function is reduced, qi and blood stagnation, run poorly, the essence of the material can not be carried up to the eyes, the eyes lose nourishment, resulting in the above eye disease.  How should I protect my eyes?  Computer time should not be too long Every 1 to 2 hours, take a break of 10 to 15 minutes, walk around the office, move your shoulder and back muscles, look into the distance to relax the tense ciliary muscles and release the continuous tension.  Maintain good eye habits Maintain a correct sitting posture, keep the distance from the screen to your eyes between 40 and 70 cm, and form a certain angle with your eyes slightly downward. If you have myopia, astigmatism and other refractive errors to wear the right glasses.  Strengthening exercise can enhance the whole body qi and blood flow, which is beneficial to the health of the eyes.  You can take time to do eye exercises at work to unblock the eye meridians.
