What are the dangers of excessive eye use

Nowadays, due to the fast pace of work and life and the high work pressure, excessive eye use often occurs, especially for some white-collar IT personnel. Their vision will be greatly affected, and they are prone to vision loss, dry eyes, night blindness or dizziness.

1. With the accelerating pace of modern work and life, many urban white-collar workers have reached the point where they cannot get anything done without computers and often feel dry eyes.

2. In fact, dry eyes are just a type of eye fatigue. If you often look at a computer or books, excessive use of your eyes will consume liver blood. Among the “five injuries caused by labor” in the Yellow Emperor’s Classic of Internal Medicine, there is one: “Prolonged staring damages the blood.” The "blood" here refers to liver blood. In fact, the eyes and liver are closely connected. "The liver stores blood", which means that the liver has the function of storing blood and regulating blood volume, and "the liver opens to the eyes". The eyes need blood to see, but overusing the eyes will cause liver blood deficiency, which will deprive the eyes of nutrition, resulting in dry eyes, blurred vision, night blindness, etc.

3. In addition, long-term sitting and using eyes will not only cause insufficient blood supply to the eyes, but also cause strain on the cervical and lumbar vertebrae. If there is no relief, it will also cause damage to the liver. In this case, it is not surprising to experience symptoms such as eye fatigue, decreased vision, and even sallow complexion and dizziness.

4. Prolonged viewing and radiation pose hidden dangers to the eye health of "computer users". This type of people need to protect their liver and nourish their blood while paying attention to eye hygiene. A combination of diet therapy and medication can be considered. In your daily diet, you should eat some animal livers such as pork liver and chicken liver, and supplement with foods rich in vitamins such as beef, crucian carp, spinach, and shepherd's purse. In traditional Chinese medicine, angelica, white peony, etc. can replenish blood, while chrysanthemum and wolfberry have the effect of improving eyesight. People who use their eyes frequently can soak them in water and drink them instead of tea.

5. Of course, this does not mean that you have to replenish blood immediately when eye discomfort occurs. Eye diseases such as refractive errors, keratitis, cataracts, etc. can cause varying degrees of symptoms such as dry eyes, blurred vision, and tearing, so one should not easily diagnose oneself as having blood deficiency. If you experience discomfort that is difficult to relieve, go to the hospital for diagnosis as soon as possible.
