Why computer visual fatigue should not be underestimated

Nowadays, many people's jobs require them to face computers for long periods of time, or they like to watch TV dramas. Facing the screen for a long time can easily cause eye problems, the most typical of which is visual fatigue. Many people do not pay attention to the impact of visual fatigue, mainly because they are not aware of the harm it causes. So, why should computer eyestrain not be underestimated? Let’s take a closer look at it below.

Studies have shown that when the eyes are focused for a long time, muscle tension will decrease, affecting the area of ​​the cerebral cortex that regulates muscle movement, thereby reducing the excitability of the nerves, causing disorder in their control over neck and shoulder muscle movements, and causing increased muscle tension. When this tension cannot be relieved for a long time, chronic pain will occur in the corresponding part.

From the perspective of traditional Chinese medicine, the essence of the five internal organs is concentrated in the eyes, which means that the eyes are connected to the body's meridians. If the eyes are too tired, it will affect the five internal organs.

It can be said that the eyes are the most vulnerable source of fatigue. If some of the following symptoms occur, you should pay special attention. When the eyes are tired, the area around the eye sockets will feel uncomfortable and painful, the eyebrows will feel sore and swollen, and symptoms such as photophobia and tearing will appear. The face will also become dark yellow, dizziness, neck and shoulder pain, and general fatigue.

To avoid this situation, you should be careful not to use your eyes for a long time. Do not watch computer or TV for more than 2 hours. Take a 10-minute break every 45 minutes. You can look into the distance, drink some water or do eye exercises. It is recommended that computer users raise their seats slightly and lower the computer, so that they can open their eyes a little smaller and keep their eyes moist. You can put some green plants in the office.

The above is an introduction to why computer eyestrain should not be underestimated. I hope it will be helpful to everyone’s understanding. The harm caused by computer visual fatigue is very serious. People who have similar work in their daily lives must be aware of its harm and take effective measures to alleviate it in a timely manner to avoid long-term visual fatigue causing great impact on our lives.
