What hurts the eyes the most?

  ”Doctor, please don’t tell my mom and dad I have bad eyes, or they’ll definitely stop giving me iPads to play with! “Recently, many ophthalmologists have encountered a similar plea. Since entering the summer holidays, the number of visits to the ophthalmology clinics of major hospitals has continued to rise, a considerable number of which are due to long-term gaze at the screens of computers, iPads, MP4 and other electronic end products causing eye dryness, visual fatigue and other problems.
  In fact, prolonged staring at the iPad, in addition to the eyes, cervical spine, spine and other parts of the discomfort and even lesions, in addition, psychological and radiation also have hidden dangers. For this reason, the reporter interviewed ophthalmology, massage, psychology and other experts to analyze how to deal with the “iPad syndrome”.
  Eyes: Subway watching electronic products make eyes very “hurt”
  Portable tablets, smart phones, so that people can access the Internet, games, entertainment, anywhere, anytime, no longer subject to the constraints of the location – a direct result of the eyes looking at the electronic terminal time multiplied.
  In the subway, you can see men in suits and ties, stylishly dressed women, students with glasses, holding IPhones and MP4s and playing them with interest. Peak hours, crowded subway, elbow a bend, the IPhone moved closer to play, some screen from the eyes is only ten centimeters away.
  Recently, the ophthalmology clinic of the Eye, Ear, Nose and Throat Hospital of Fudan University is full of people, and there are many students among them. The attending physician of the Glaucoma and Optic Nerve Disease Department of the Eye, Ear, Nose and Throat Hospital, Kong Xiangmei, said that it is a very bad habit to read books and play with electronic products in a mobile environment such as the subway.
  Many people may not play cell phones in the car, because not look long people will feel dizzy and can not continue, but will play electronic products in the seemingly smoother subway and train. But in fact, in the subway than in the car to watch video screens, play games is worse. Because there are no obvious symptoms of dizziness to remind themselves to stop looking at electronic end products, people will stare at the screen for a long time without realizing it.
  Dr. Kong suggested that to reduce the damage to the eyes, it is best to change the habits of the road, listen to music on the subway, let the eyes rest, people can also get a good relaxation. She also reminded that the mobile TV in the subway car can be watched for a short time, a long time to stare at it can also hurt the eyes.
  ”One light alone” is the most harmful to the eyes
  Dong Jie recently spoke on Weibo and said, “Now the children’s proficiency on the IPhone really makes me sad and happy. “And there are more than ten million parents who hold the same view.
  In colleges and universities, the night dormitory is always “starry”, one by one “cell phone lights” lit up at the head of the bed, which seems to have become an indispensable entertainment time for students before going to bed.
  The increasingly powerful functions of cell phones have greatly enriched the dormitory life of students and made them unconsciously spend more time on bedtime entertainment. Moreover, this can also avoid disturbing other students’ rest.
  Similarly, sometimes, in order not to disturb other students’ rest, students who play computer will considerately turn off the dormitory lights and continue to play with the computer alone.
  This phenomenon of “one light alone” is particularly harmful to the eyes because of the strong contrast of light. Likewise, reading books and playing with electronic products in the sun, the strong light will also stimulate the eyes.
  Dr. Kong cautioned students, first of all, to avoid reading in the sun, play electronic products; second, the background lighting of electronic products are now adjustable, we can adjust the background lighting of electronic products to soften some, and beige is a good choice, compared to other colors, the damage to the eyes is relatively small.
  Cervical spine: the smallest “screen control” only five or six years old
  Carry, a female white-collar worker, spent nearly ten hours every day for three or four months playing with her newly purchased iPad, and as a result of maintaining the same posture for a long time, she developed finger weakness, upper arm inability to lift, and neck inability to move symptoms. When she went to Shuguang Hospital of Shanghai University of Traditional Chinese Medicine to take an X-ray, it showed that the cervical curvature was backward and the vertebral space was narrowed. Such cases are often encountered in the massage department of Shuguang Hospital.
  According to the data of the hospital, 60% of the patients who come to the massage department are caused by prolonged use of electronic products, among which 10% of the cases are caused by IPad and IPhone, and the youngest patient is only five or six years old.
  Zhu Guomiao, an attending physician at Shuguang Hospital’s massage department, calls these people who can’t leave the screens of computers, cell phones and televisions and other electronic products “screen controllers”, and the long-term incorrect use of electronic products makes these people prone to neck and back pain, even carpal tunnel syndrome, finger tenosynovitis and other diseases.
  Since the birth of touch-screen cell phones, all kinds of touch-screen games have come into being. The female college student Xiao Sun a while ago hooked on the fruit ninja, regardless of class, rest, are trying to cut melon, a long time, found their fingers numb, weak, inactivity, the emergence of the commonly known “slingshot finger”.
  This symptom is medically called finger flexor tendon tenosynovitis, in serious cases, the development will lead to nerve damage, which in turn causes finger muscle atrophy.
  We may all have this experience, cell phones, computers once played up, will forget the time, head and screen unconsciously closer and closer, maintain a posture for a long time, do not move a bit.
  Dr. Zhu said that such bad habits of modern people tend to lead to cervical spine compensatory hyperplasia. Cervical hyperplasia can compress the nerve roots, causing neck and back pain, upper limb pain and numbness and even limited activities, and in serious cases, life can not take care of itself. Cervical spine hyperplasia can also lead to compression of the vertebral artery supplying the occipital part of the brain, causing abnormal blood supply to the occipital part of the brain, resulting in symptoms such as headache, dizziness and memory loss.
  Long-term forward leaning posture can easily trigger lumbar spine hyperplasia and cause tension and loss of elasticity in the posterior longitudinal ligaments, resulting in lumbar disc protrusion and compression of nerve roots. If the sciatic nerve is compressed, it can lead to radicular sciatic nerve pain, low back pain, lower limb pain and mobility disorders.
  In the face of such patients, Dr. Zhu, in addition to traditional Chinese medicine massage, the most important thing is to exhort patients to stop or reduce the time of use and strengthen the time of exercise, so that the symptoms will slowly improve. But the objective reality is that most patients do not recover very well, because they can not control themselves, it is difficult to get rid of electronic products. Dr. Zhu reminded that when using electronic products try to correct the posture, do not lower the head for a long time, there should be appropriate exercise to relax.
  Radiation: electronic products, more or less a little radiation
  A British office electromagnetic wave study confirmed that the low-frequency radiation and magnetic fields emitted by computer screens can lead to 7-19 diseases, including itchy eyes, neck and back pain, short-lived memory loss, irritability and depression. Women are also prone to reproductive abnormalities and abnormal embryonic development.
  According to a survey of more than 200 computer operators in the banking system in Wuhan, more than 35% of women experienced dysmenorrhea, prolonged periods, and a few women had premature births or miscarriages.
  According to a study by the World Health Organization, pregnant women who use computers for more than 20 hours a week have an increased incidence of miscarriage by more than 80%, which may also lead to fetal malformations.
  Microwave damage to the human body from electronic products, the reason for this is that the low energy of electronic products and low-frequency electromagnetic radiation X-rays, easy to cause people’s central nervous system disorders, this damage is very direct.
  Psychological: Quit “screen addiction” balance is the key
  Young people are full of enthusiasm for the pursuit of new and fashionable technology products, which is a characteristic of the younger generation. However, long-term addiction to them, will appear abnormal personality, withdrawn and autistic, reluctant to communicate with others, many parents are also worried that their children will waste their studies, play with things.
  According to Diao Jing of the Counseling and Psychological Development Center of Shanghai University of Traditional Chinese Medicine, there are various reasons for this kind of behavior: first, it is a way to relieve the pressure of reality and vent the irritation of the heart by playing games; second, some people are escaping from the real life and retreating from the difficulties, they choose to face the screen and temporarily do not face the problems they encounter; third, the environment they live in does not provide them with meaningful opportunities to participate Fourth, they are doing it as a way to enjoy themselves and balance their lives.
  These people’s behavior is completely in line with the needs of the heart, and at the same time, from a side reflection of their lack of good planning for life. Therefore, to get rid of the obsession with electronics, she suggests shifting their attention, exploring meaningful engagement opportunities with them, and providing platforms for them to reach out.
  The amount of time each person spends playing with electronics depends on whether it interferes with other normal things in their lives. Therefore, there is no precise time for the definition of addiction, and it depends on whether a person’s psychological needs can be balanced in life.
  [Tips] Decide whether to wear glasses after distinguishing true from false myopia
  It is normal for children to be farsighted until they are 6-7 years old. After the age of six or seven, this condition will disappear and vision will tend to be positive. Now more and more children are becoming “nearsighted” at the age of six or seven. However, Dr. Kong cautions that it is important to distinguish between true myopia and pseudomyopia at this time.
  Pseudophakia is a condition where the test result is myopia, but the ciliary muscle paralyzing agent is put into the eye to relax the eye muscles, and the result of the vision test is normal. During the summer, over 1,000 children come to the Eye, Ear, Nose and Throat Hospital every day for dilated refraction testing.
  Both children and adults, usually have to develop a good reading posture, whether reading or playing with electronic products, at least maintain a distance of more than 30 cm, while, at the same time, and eye forward flat 90 degrees as the standard downward tilt of 15-40 degrees for the best human field of vision pitch angle.
