How Should Computer Vision Syndrome Be Prevented?

In today's information age, computers have become indispensable for white-collar jobs. However, medical experts point out that people who work in front of computers for a long time feel uncomfortable in varying degrees.

According to a survey conducted by the National Institute of occupational health and safety, 90% of the people who worked for more than 3 hours a day before the computer had problems with their eyes, such as dry eyes, headache, irritability, fatigue, and difficulty in concentrating. This kind of computer vision syndrome is a typical dry eye disease.

Medical experts believe that computer vision syndrome is a relatively new type of disease, more than half of the computer users, more or less have or often suffered from the disease.

In the face of such a common white-collar work sickness, how should we prevent and diagnose it?

High risk groups: computer game fans and financial personages

Computer game players watch the screen for a long time, making the eyes easy to strain.

Because the computer screen is not as clear as the black words on the paper, the edges of the images are blurred, the eyes are not easy to get the focus, and the activity of the picture needs to be refocused again, so that the regulating muscles in the intraocular lens need to constantly adjust to see the image. Therefore, the larger the computer screen, the greater the eyesight loss.

In addition, too much attention is focused on not blinking. Eye doctors think that is the key.

Computer operation is a highly concentrated vision, which reduces the secretion of intraocular lubricants and enzymes.

Generally speaking, if a person blinks less than 5 times per minute and has a longer duration, it will make the eyes dry and tired, with heavy vision, blurred vision and headache and neck pain.

Patients who catch up with TV dramas do not appear to be obsessed without blinking, but the number of them is less than that of ordinary computers. The reason is that watching TV is more leisurely and commercials, and people's attention is also low. However, people who use computer games or Internet users may concentrate on forgetting blinking. Foreign countries have studied to observe machine fans, and found that they do not blink once on average for more than 2 minutes, which is very damaging.

Ophthalmologists also pointed out that although teenagers are addicted to playing games, people with computer vision syndrome are still familiar with the above classes, because the disease is caused by accumulated strain.

Among them, people engaged in financial work still need to pay attention to foreign stock market when they are at night. Their work and rest often do not match with the physiological clock. This will have a greater impact on vision health. They are also a high-risk group suffering from computer vision syndrome.

Consequence: the time of using "brain" is getting shorter and shorter.

Ophthalmologists believe that watching the screen under proper use of computers will not have any effect on vision health, but the problem is that many people tend to have "overspending with eyes".

This leads to computer vision syndrome.

The main symptoms of computer vision syndrome are eye fever, dry eyes, eye irritation, eye congestion, congestion and serious photophobia, difficulty in eye opening, and eye pain. However, most of the patients do not care about it at the beginning of their symptoms. Later, however, they are mistaken for the idea of "dry eye" or "tired eye" because they are accustomed to these symptoms, so that they can delay treatment and increase the risk of structural problems such as imbalance in secretion of tears.

In general, people who use computers may be able to watch the screen for 8 hours a day.

But in the years of strain, the time to "see" will be shorter and shorter. There are patients who work on computers for a long time. They start working at 9 every morning before they start working on computers. When they are 10, their eyes are too dry to look at the screen. Some patients become seriously photophobia, so they need to wear sunglasses in the indoor environment.

Symptomatic: prolonged medical treatment requires a temporary cure.

When the eyes are looking at the screen, there are abnormal eye dryness, eye fatigue, and so on. The doctor suggests that as long as you first rest your eyes for a week, then watch the screen again, pay more attention to the 6 points of "computer hygiene" and have enough rest. Basically, the disease can be cured without any medicine.

However, if it is prolonged for more than a month, it may cause structural problems of visual health, such as decreased secretion of tears, imbalance of tears, and so on.

Deconstruction of tears, water is the main ingredient, its surface will have a layer of water to prevent evaporation of oil, and the bottom of the tears will have a layer of protein, the role of tears in the cornea to increase the moisture.

If you suffer from computer vision syndrome, the tears will be easily imbalanced. The most common thing is lack of water, too little fat or too much protein, or insufficient secretion of protein, forming similar symptoms such as dry eye and eye irritation.

Medical experts believe that when the problem has been related to the structural problems of tears secretion, we must use drugs (moisturizing eye water) to supplement the insufficient water, grease or protein.

However, it should be noted that when there is a dry eye, avoid using eye drops, because this part contains preservative ingredients.

So we must go to the hospital and follow the doctor's advice.

In addition, oral drugs such as fish oil pills and enzyme have proved that they can effectively enhance the moisturizing degree of the eyes, and many patients have improved their condition after taking them.

Secret: six key points of "computer health"

1. do not put the computer on the side of the window to avoid the reflection of light from overhead and cause the computer screen to be unclear.

2. the height of the top of the computer screen is slightly lower than that of the eye's horizon. The best place to put it is that the center of the computer screen should be about 20 degrees below the line of sight.

3. the computer screen and the eyes are 60 centimeters apart.

4. often blink your eyes to increase the secretion of tears, so as to moisturize the eyes.

5. the reference material will be placed on the file bracket beside the computer, so that you do not have to turn your head back and forth, so your eyes do not need to adjust the focal length frequently.

6. staring at the computer screen, every 1 hours should rest for 10-15 minutes.

If you can close your eyes to complete rest, or look at things outside 5 meters, you can also get rest, or do eye exercises.
