Subway, bus, eyes glued to the little MP4 (multimedia audio and video player) swaying with the car can not turn a blind eye; while walking, while holding the PSP (handheld game console) to play forgetful; to the office, the first time to open the computer to browse the website headlines; business trip in the plane, still do not forget to open the screen on the seat to watch a Korean drama … … …The various and ubiquitous handheld video products have almost become the new symbol of the current urban “hipsters”. In the era when computers just started to become popular, ophthalmologists will face the computer all day long with visual fatigue, back pain and other symptoms called “computer syndrome”; however, with the development of technology, PSP, MP4 and other handheld video in the urban population is becoming more and more popular, medicine also “keep up with the times However, with the development of technology, PSP, MP4 and other handheld videos are becoming more and more popular among the urban population, medical science has also “changed its name” to “video terminal syndrome”. “This syndrome will not necessarily seriously damage vision, but can make people’s eyes uncomfortable all day long.” The video all day long 70% of people will have visual impairment Xiao Guo work in an advertising company, just open his bag you will find that he is a true “hipster”, which is stuffed with all kinds of electronic products: PSP, handwritten and e-mail cell phones, laptops … … “My favorite is electronic products, except for sleep, my time is contributed to them.” Because of his busy work schedule, he often stitches on the way to visit customers and travel all the way to play PSP games or read the latest downloaded e-books. But he said, look down for a long time eyes are very tired, neck pain, and occasionally blurred vision. Despite this, he still has trouble letting go of his dependence on various video products. ”We used to call the eye disease suffered by these patients who spend their days on the computer ‘computer syndrome,’ but now it seems that ‘video terminal syndrome’ seems more appropriate.” This is because in recent years, from computer screens to TVs, PSPs, MP4s, cell phones and other large and small screens are flooding the lives of urbanites, whether at home, in the office or on the way to and from work, they are constantly staring at all kinds of videos, and the resulting “video terminal syndrome” is becoming more and more common. Many patients in the clinic complained to the doctor: just after a night’s rest, but in the morning, soon after turning on the computer again feel uncomfortable eyes. In the afternoon, the eyes may also appear red, congested, secretions overflowing and other symptoms. “These are typical signs of ‘video terminal syndrome’, and 70% of people who spend too much time with their eyes on computers and other videos will experience visual fatigue or visual impairment.” Huang Wenyong said. Blink more often to deal with video terminal syndrome When you’re looking at a screen such as a computer, your mind is inevitably highly focused, so you forget to blink. A decrease in the number of blinks can directly lead to a decrease in tear production. The loss of tears can cause damage to the cornea over time. In addition, people in the face of video, the eye must constantly adjust the focus to ensure a clear view, the adjustment function at any time in the “battle” state did not get a rest, so visual fatigue, blurred vision is inevitable. Finally, the various rays emitted by the screen can also stimulate damage to the eyes. Therefore, it is very common to see dry eyes, blurred vision, and even head and neck pain after watching videos for a long time and with high intensity. “Many people slowly suffer from corneal and conjunctival inflammation as a result.” It is understood that the common symptoms of video terminal syndrome are: decreased visual function and eye dryness, redness, congestion, foreign body sensation and other types of discomfort; headache, shoulder pain, lumbago and numbness in the finger joints of the limbs; mental inattention, mental fatigue, etc. ”In the end, how long to use the eyes every day is reasonable, in fact, there is no very specific rules, but the key is to face the video for a long time should be interval rest, relax the eyes.” Be sure to develop scientific eye habits, prolonged high-intensity eye use is the “enemy” of the video terminal syndrome, every hour of work should be active rest for a while before continuing.
