Mobile phone "control", playing with eye fatigue
Iphone and ipad are very popular among young people. This kind of mobile phone combines the functions of mobile phone and computer. It can make phone calls, send text messages, chat QQ online and play the game of "knitting scarves". It is so powerful that people can't live without it. Everyone's information enriches their lives, but makes their eyes the hardest hit.
Associate Professor Jun Hong, director of the Health Department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said that long-term use of mobile phones to surf the Internet is the most likely to cause eye fatigue. Small fonts on the screen of a mobile phone are much more "eye-consuming" than watching a computer or TV. Users must be highly focused and stare without blinking or lifting their eyes. Blink less, be stiff in one posture, and your eyes are particularly tired. Some people often say that the eyes shed tears inexplicably, the eyes are tired, the eyes are dry, the eyes are hazy, the eyes are itchy and painful, and the eyes are sore. This is the performance of eye fatigue.
"This situation is particularly easy to happen to office workers with strong eyes. They can't work without a computer during the day. On the way home, when waiting for the bus, they still use their mobile phones to surf the Internet. They stay up late playing games and cooking DVDs without giving their eyes a rest. Of course, this will have such bad consequences. " Jun Hong explained that human eyes, like other organs, have blood circulation and metabolism, and also produce metabolites. Adequate eye rest is not only the need of normal physiology, but also the basic guarantee for its better work. If the normal circulation is disturbed and the eyes are not rested and buffered, a warning signal will be issued, and the above discomfort-eye fatigue will occur. Only adequate rest can relieve fatigue and restore normal operation.
Basic eye care
Control the use time
"It is most important to relieve eye fatigue and control the time of using video products (including mobile phones, computers and game consoles). This is the basic method to prevent eye fatigue. If you can't control the use time, all other interventions will be discounted. " Jun Hong said. With iphone and ipad, some people need to work, while others are following the fashion. As long as conditions permit, don't choose to use a mobile phone when you can use a computer. After all, the computer screen is big and the font is big, which is less harmful to the eyes, and the posture of sitting in front of the computer is less harmful to the joints than the posture of holding the mobile phone with the head down.
In addition, using mobile phones to play screen-jumping games, or using mobile phones when bumping or walking in the car, is particularly harmful to the eyes, and should be stopped in this environment.
Overlooking relieves eye fatigue
For people who like to use mobile phones for entertainment, ensuring adequate sleep, moderately closing their eyes and farsightedness are the basic methods to protect their eyes. Although the world of mobile phones is wonderful, people can't stop, but after using them for 45 minutes to ~ 1 hour, you must stop for a few minutes and look into the distance. Staring at the screen of the mobile phone for a long time, the tendinous muscles of the eyes are in a tense contraction state, but at a suitable time, the tendinous muscles of the eyes are in a relaxed state, which can relax the muscles and tissues of the eyes and effectively relieve fatigue.
Blink frequently and do more eye exercises.
In addition to looking at the distance, doing eye exercises with your mobile phone for an hour or so is also a good way to protect your eyes for a long time. It is unrealistic for busy adults to do eye exercises four times in a row. You can simply do the action of "pressing the temple and scraping your eyes in turn", which will dredge the meridians, improve the blood circulation of the eyes and be of great benefit to the metabolism of the eyes. Moreover, this action will not touch the eyeball, which reduces the chance of eyeball being infected by bacteria.
Under normal circumstances, people blink about 15 times per minute, but when operating mobile phones, especially playing games, their attention is highly focused on the screen. Unconsciously, the frequency of blinking will be significantly reduced, leading to excessive and rapid evaporation of tears, dry eyes and other problems. Therefore, mobile phones should "control" their blinking more consciously.
If the above methods still can't relieve eye fatigue, Jun Hong thinks that a few drops of anti-fatigue eye drops can be dropped. If the symptoms are still not relieved, be sure to stop using your eyes and let them rest completely.
Adjust your mobile phone and protect your eyes.
Eye fatigue caused by surfing the internet with mobile phones has been summarized by ophthalmologists as one of the manifestations of "video terminal syndrome" in recent years. The so-called "video terminal" includes computer monitors, televisions, game consoles and mobile phone screens. These video products have been fully integrated into the daily life of most people. In order to avoid "video terminal syndrome" as much as possible, you can adjust the font and color of the screen to protect your eyes. But it should be emphasized that it is most important to play mobile phones less.
It is not easy for a smoker to quit smoking successfully. Besides eating melon seeds and sugar, scientists have discovered new ways to quit smoking.
A few days ago, New Zealand scientists found that using text messages to quit smoking can double the success rate of smokers, New Scientist reported.
Text messages are designed to encourage smokers to quit smoking, help them to relieve their symptoms in the process of quitting smoking, or distract them by providing topics unrelated to smoking, such as music and sports information.
Choose a soft background color.
Too bright colors on mobile phone screens and mobile phone web pages will invisibly increase the working intensity of eyes. You can try to adjust the brightness and contrast of the mobile phone screen and change the background color, so that the screen brightness is softer and has a certain contrast, but it will not be too dazzling. It is best to adjust the background color of the webpage to soft tones such as brown and orange. In addition, it's best to make the font of the mobile phone bigger, which looks less laborious and doesn't need to pay special attention to staring at the screen.
Don't play with your mobile phone in the dark.
Improving the environment also helps to relieve eye fatigue. I believe you have such an experience. When you turn off the lights and watch TV in the dark, your eyes will soon get tired. Because the light contrast between the display and the background is too big, it increases the fatigue of the eyes. Therefore, in the dark, especially at night, although the mobile phone has brightness, it must turn on the lighting and don't "work in the dark". In addition, pay attention to the "beautiful position" of the mobile phone, and choose a position where light or natural light will not reflect to the eyes through the screen of the mobile phone.
Keep the air-conditioned room moist.
At present, the midsummer is coming, but the delicate urbanites have turned on the air conditioner early, which is also one of the reasons for dry eyes. Using air conditioner to make indoor air too dry will increase the evaporation of tears in eyes and aggravate the dryness of eyes. Therefore, everyone should also pay attention to the ventilation of the room and maintain a certain humidity.
Mobile phone "control", playing with shoulder and neck pain
Holding a mobile phone and clicking the interface with your thumb and forefinger is a classic picture for mobile phone users. It not only hurts the eyes but also hurts the neck and shoulders, and it also has potential damage to the joints of the hands. In fact, this is also a kind of "video terminal syndrome". Judging from the current outpatient situation, there are fewer patients who play hand joint problems with mobile phones, which may be related to the fact that most users are young people, but patients who play shoulder and neck problems are very common.
Associate Professor Yang, director of the Sports Injury Department of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that one patient was hospitalized for playing mobile phones. There is something wrong with the patient's cervical vertebra. When he is free, he plays online games on his mobile phone. He himself often feels numbness and pain in his arm, but he doesn't care too much. One morning, I got up and found my hand was too painful to lift. There was a burning or stinging pain that made him cry. When he was admitted to the hospital, he found that he was suffering from "cervical spondylotic radiculopathy". The cause of this disease is that he plays mobile games for a long time, which makes his neck, arms and cervical vertebrae stiff in a posture for a long time, and the nerve roots of his neck are compressed, resulting in unbearable tingling.
Mobile phones are small in size. People often hold their mobile phones in one posture and often lower their heads. They focus on the virtual world for a long time and are not active. This will naturally cause tension and strain of the shoulder and neck muscles, which will make people's shoulders ache and neck ache. People who have potential cervical and cervical problems themselves, like the above situation, are likely to induce diseases.
Today's smart phones are mostly "touch screen" operation, which can be input by hand. So, is it harmful to turn off your fingers and wrists? Yang believes that in theory, excessive use of fingers for a long time may indeed cause hand problems such as finger tendinitis and snapping fingers. However, from the current clinical cases, this kind of finger joint strain often occurs in craftsmen, designers, repairmen and other people who often use their fingers hard, while clicking on the screen and writing with their fingers is only a gentle operation with little strength.
In order to prevent neck and shoulders from appearing, it is the last word to reduce the time of operating the mobile phone. From the point of view of eye care, you should rest for a few minutes after 1 hour and look far away to relieve eye fatigue. From the point of view of protecting shoulder and back joints, arms, shoulders and neck are prone to stiffness and pain for ten minutes. Look up, lift your neck, twist your neck back and forth, and move your fingers. Don't be stiff in one position for a long time. In addition, if you make a phone call, don't hold your mobile phone in your hand. Use earplugs instead.
