Today, with information technology, computers have become indispensable for white-collar workers. However, medical experts point out that people who have been working in front of a computer for a long time may feel unwell to varying degrees.
According to a survey by the National Institute of Health and Safety, 90% of people who work 3 hours a day in front of a computer have problems with their eyes. The symptoms are: this 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 computer users, more or less have or often suffered from this disease. How can we prevent and diagnose such a common white-collar work problem?High-risk users: computer game fans and financial users
Computer gamers can watch the screen for a long time to make their eyes easy to work. Because the computer screen is not as clear as the black text on the paper, the image edge is blurred, the eyes are not easy to get the focus, and the screen has to get the focus again after an activity, as a result, the regulating muscles in the eyeball crystal need to constantly adjust to see the image, so the computer screen is much more, the larger the loss of vision.
In addition, eye-fixing is also critical for ophthalmologists. Computer operations are a relatively concentrated job of vision, which reduces the secretion of lubricants and enzymes in the eye. In general, if a person blinks for less than five times per minute and lasts for a long time, the eyes will become dry, tired, and have symptoms such as shadow, blurred vision, and neck pain.
It is not because of the fact that the patients who get caught up with TV series are not confused, but there must be fewer computers than normal. The reason is that watching TV is idle and there are advertising spaces, people are less focused, but computers or netusers may be focused on forgetting to blink, and foreign researchers will be observing machine fans, they found that they would not blink once on average for more than 2 minutes, which was very eye-catching.
Ophthalmologists also pointed out that although teenagers are addicted to computer attacks, computer vision syndrome patients are still common in office workers because they all suffer from accumulated labor loss, office workers have been using their "brains" for a long time. Naturally, they are not so banned and are more likely to suffer from disease. Financial employees are still online to pay attention to foreign stock markets after night, and their daily routine and physiological clock often do not work with each other, which has a greater impact on visual health, they are also high-risk people with computer vision syndrome. These people often start to suffer from computer vision syndrome in half a year.Consequence: the "brain" time is getting shorter and shorter
Ophthalmologists believe that the correct use of computers does not affect vision health. But the problem is that many people tend to overspending their eyes. This leads to computer vision syndrome.
Computer Vision syndrome symptoms are mainly when you look at the screen, the appearance of eye fever, dry eyes, eyes, red eye congestion, and serious when the light, eye widening difficulties, eye pain and other conditions, but in the first symptoms, most of the patients do not mean it, but because they are "used to" these symptoms, they mistakenly think that everyone in the computer will see dry eyes, tired eyes and other ideas, resulting in delayed treatment, increase the risk of structural problems such as imbalance in the secretion of tears.
Usually, first-time computers will be "too busy", and may be able to watch the screen for 8 hours a day. However, after years and months of Labor loss, the time for "reading" will be shorter and shorter, and there will be patients who have been working on computers for a long time, even if you start working at 9 o'clock every morning, your computer will be turned on, and your eyes will not be able to screen again when 10 o'clock is done dry. Some patients will also become very light-shile, even if you need sunglasses in the indoor environment, it is more comfortable to view objects.Symptomatic: Medical extension requires medication for a long time
When the eyes look at the screen with abnormal dry eyes, tired eyes and other discomfort, the doctor recommends that you just give your eyes a week's rest, when you look at the screen, pay more attention to the six key points of "Computer health" and have enough rest. Basically, this disease is getting rid of medicine. However, if the doctor stays in medical care for more than a month, it may cause structural problems of vision and health, such as reduced secretion of tears and unbalanced composition of tears. It is necessary to use drugs to "cure the symptoms.
Deconstruct of tears, water is the main component, its surface will have a layer of oil to prevent moisture evaporation, and the bottom layer of the tears will have a layer of protein, in the role of promoting tears attached to the cornea, increase its moisturizing. If you suffer from computer vision syndrome, tears may be prone to imbalance, the most common is lack of water, too much oil or too much, or lack of protein secretion, forming similar symptoms such as dry eyes, eyes and so on.
Medical experts believe that when the problem involves the structural issue of the secretion of tears, drugs (eye-shining water) must be used to supplement the insufficiency of water, grease or protein. But it should be noted that when there is a dry eye microlike, do not use eye drops, because this is related to some of the preservatives, after the drops will increase the condition. In addition, oral drugs such as yuyou pill and enzyme have proved to effectively improve the moisture of the eyes, and the condition of many patients is also improved after use.TIPS: six key points of "Computer health"
1. Do not place the computer in the window to avoid the reflection caused by the light source from the top of the head, resulting in unclear computer screens.
2. the height of the top of the computer screen is slightly lower than that of the eye. The ideal position is that the center of the computer screen should be around 20 degrees below the eye sight.
3. the computer screen and eyes are 60 cm away.
4. blink your eyes frequently to increase the secretion of tears and moisturize your eyes.
5. Place the reference materials to be used on the file holder next to the computer, so that you do not need to rotate the neck and head back and forth, and the eyes do not need to adjust the focal length frequently.
6. You should rest for 10-15 minutes every other hour. If you can, please close your eyes to have a full rest. Or you can rest your eyes when you look at something 5 meters away. Or perform eye exercises. If you put your hands on your eyes, the function of promoting blood circulation is available.
