There have been previous reports of the risk of long-term sighting of mobile phones, computers, especially in dark environments. In an interview with a journalist, on 17 december, during a training course on media health dissemination organized by the beijing hospital authority, the beijing municipal councillor, wang ningli, vice-president of the same hospital, stated: “the damage to eyes caused by electronic products such as mobile phones and computers is positive, but there is no conclusive evidence that long-term sighting of mobile phones and computers can lead to blindness”
Long-term access to mobile phones and computer-based video terminal syndrome
Wang ningli said it was true that experts had previously conducted safety assessments in this regard, but that such assessments generally carried out some acceleration tests. The current science does not explain the causal link between long-term reading of a mobile phone or computer and blindness。
Wang ningli stressed, however, that long-term viewing of mobile phones and computers could have an impact on the eye. We blink when we look, and if you read the contents of a mobile phone, computer, too much attention is focused, there will be a “forgotten effect”, and the number of blinks will be significantly reduced, thereby causing the protective layer of the eye surface, the evaporation of the tear membrane, to the detriment of the upper membranes and the condensation; moreover, prolonged reading, with the eye being in a state of constant regulation, will lead to visual fatigue, resulting in dilation, swelling and tears, which is called video terminal syndrome。
Increased near-sightedness of electronics cannot be ignored
“the long-term cumulative effect of electronics, such as mobile phones and computers, on eye damage requires urgent attention and intensified research.” wang ningli indicates that it is now certain that a long period of close viewing of a mobile phone and a computer can exacerbate a close look. The early use of mobile phones and computers by children is an important reason for their near-sightedness。
At present, cataracts are the first eye disease leading to blindness in my country. However, the cataract surgery is mature and can be seen by the patient after it has been performed. “at present, our greatest concern is a high degree of near-sightedness, particularly in the sense of the disease, with a prevalence of 0. 9 to 1. 3 per cent, which has become one of the country's top blinding diseases.” wang ningli said that, in a series of degenerative pathologies at a height of near-sightedness, post-synthetic osmosis was one of the most basic causes of hysteria, which aggravated the pulsation of the pulsation, resulting in a series of pathologies such as haemorrhage, seepage, lewdness, newborn blood vessels, and oscillation, which in turn seriously damaged the patient's vision and even lost sight。
In addition, there is a relationship between high near-sightedness and glaucoma. There was a high incidence of closed-angle and open-angled glaucoma in the 1980s, which was somewhat related to the high number of people with long-sighted eyes。
“the incidence of closed-angle glaucoma has declined in recent years, while the incidence of open-angle glaucoma has risen. At present, the prevalence rate is 1. 96 per cent global, but our country has reached 2. 6 per cent. This is the "contribution" of the rapidly rising near-sightedness of our country." wang ningli stated that the traditional perception was that high-eye pressure was the main cause of glaucoma, while over 80 per cent of the country's original open-angled glaucoma patients had low eye pressure. The study found that this was closely related to the near-sighted eye. The likelihood of open-angle glaucoma is greatly increased as the close-sightedness of the eyes increases, the eye is gradually stretched, the wall of the filament is thinner and the eye is less resistant to pressure。
Wang ningli reminds people with near-sighted eyes not only to look at whether the near-sightedness is increasing, but also to have doctors check their eyes regularly to see if they have any glaucoma. In addition, it is necessary to control the timing of mobile phones and computers。
Put a blue-lighted film on your phone
"my cell phone is different from yours, and i put a blue-light-proof film on it. You see the blue reflection from the side, but this film has no effect on the image and color of the phone." wang ningli's mobile phone attracted journalists' attention。
Studies have shown that blue light waves are long and energy high and can reach the yellow spots directly through the crystal. Permanent exposure to blue light on the mobile phone screen can lead to yellow-blank variability, which is irreversible. However, yellow-stained transsexuality is an important blinding disease among the elderly. In addition, blue light tends to lead to eye fatigue。
A blue-light-resistant film on the mobile phone helps to protect the eyes from blue-light damage and to ease the fatigue. However, wang ningli also indicated that the current assessment of the damage to human health caused by mobile phones, including radiation, damage to hearing and brain and damage to the eyes of screen blue light, is short-term and long-term assessment data are not available。
Wang ning uses red, yellow, white, blue and purple to describe the spectrum of ophthalmological diseases of our population today. “red” represents haemorrhage in the eye caused by metabolic diseases, cardiovascular diseases, etc.; “yellow” means yellow-stained variability; “white” means cataract; “blue” means glaucoma; and “purioc” means retinasis caused by high near-sightedness。
Strengthening ophthalmic disease control requires more specialist ophthalmologists. However, there are currently more than 35,600 ophthalmologists in the country, and the number of ophthalmologists per 100,000 people is far from that of developed countries. “as a result of our efforts, the number of patients with cataract surgery per million population has risen from more than 400 to 1,400, with coverage of 90 per cent if it reaches the level of 2,200 to 2,300. The training of ophthalmologists should be strengthened from the perspective of the fight against cataracts and other eye diseases.” wang ningli's appeal。
