Nearsighted white-collar workers are more likely to suffer from glaucoma

Abstract: a Japanese study found that if you face the computer screen for more than 9 hours a day for a long time, the probability of suffering from glaucoma is twice that of others, and myopic people who face the computer for a long time are at high risk of glaucoma. According to the data of who (World Health Organization), glaucoma is the second blinding factor in the world., The office is the hardest hit area of light pollution. Generally, all kinds of light that affect the natural environment, adversely affect human normal life, work, entertainment and rest, damage human ability to observe objects, cause human discomfort and damage health can be classified as light pollution. At present, light pollution is mainly divided into three categories: white light pollution, artificial day pollution and daylighting pollution., Blocky glass curtain walls, glazed brick wall interiors, polished marble floors… Well decorated offices are often the hardest hit areas of light pollution. The light reflected by building materials and paint decoration is mostly bright, white and dazzling. People who work long hours in a white and bright environment will suffer varying degrees of damage to their retina and iris. In other words, the eyes are sour and tired, which is likely to have a “credit” for the office environment. In the long run, dizziness, loss of appetite and depression may come to the door., Artificial day, we will not be strange. In the city at night, neon lights and shop signs are shining, and the huge buildings are set off by strong lights. In short, the night has been forgotten in the pile of old papers, leaving only the man-made day., Such a “sleepless city” affects people’s physiological rhythm, makes it difficult to sleep, and will affect the work efficiency of the next day. Lepidopteran entomologist Kennet francer in Philadelphia, USA, has long found that silkworm moths often miss the opportunity to have sex because of the misleading lighting., Lighting is also a kind of drug. In 2001, a study published in the Journal of the National Cancer Institute showed that a survey of 1606 women at a cancer research center in Seattle found that women working at night had a 60% higher rate of breast cancer compared with non working women at night. The longer the night shift, the higher the intensity of exposure to light, and the greater the possibility of illness.,

artificial day, we will not be unfamiliar. In the city at night, neon lights and shop signs are shining, and the huge buildings are set off by strong lights. In short, the night has been forgotten in the pile of old papers, leaving only the man-made day.

and other “non night cities” affect people’s physiological rhythm, make it difficult to sleep, and will affect the work efficiency of the next day. Lepidopteran entomologist Kennet francer in Philadelphia, USA, has long found that silk moths often miss the opportunity to have sex because of the misleading lighting.

. In 2001, a study published in the Journal of the National Cancer Institute showed that a survey of 1606 women at a cancer research center in Seattle found that women working at night had a 60% higher risk of breast cancer compared with women who worked not at night. The longer the night shift, the higher the intensity of exposure to light, and the greater the possibility of illness.

in short, the night owl type of work reversed day and night is not only unconventional, but also harmful to health.

and

workers should be organized and colorful during the day, and not free at night: in and out of commercial cocktail parties and luxury clubs. Aside from drinking and staying up late, the colorful and dim lights do great harm to people. This is color light pollution. Black lights, rotary lights, fluorescent lights and stroboscopic color light sources in the club constitute color light pollution.

and

black light lamps produce much stronger ultraviolet light intensity than that in sunlight, and the harmful effect on human body lasts longer. Prolonged irradiation may induce nosebleed, tooth loss and cataract. Stroboscopic color light dazzles people, which is not only harmful to the eyes, but also interferes with the central nervous system, makes people dizzy, accelerates the aging of skin cells, and even presents symptoms such as nausea, vomiting and insomnia, leading to sub-health. Recent studies have shown that color light pollution may also endanger mental health. From this point of view, light is indeed a “latent person” who destroys human health.

“light is a kind of drug. Abusing light is harmful to health.” This is what Russell Reiter, an endocrinologist at the Texas Health Science Center, said. As a melatonin research expert, he found that the light on the retina at night would reduce melatonin production. This hormone is an important substance to regulate circadian rhythm. For example,

and

, the “flying man” who often crosses the ocean has to get jet lag. In fact, it is to catch up with the circadian rhythm of adaptive hormones. The normal circadian rhythm is the “magic weapon” brought to mankind by hundreds of millions of years of natural evolution – work at sunrise and rest at sunset. Light plundered the time of night for no reason, disrupted the rhythm of hormone secretion, and the normal cycle began to be unbalanced.

excessive exposure to light at night may also lead to depression. This result was released by Professor Randy Nelson of Ohio State University at the American neuroscience annual conference held in Chicago on the 21st of last month. Nelson’s team found that mice kept in a 24-hour brightly lit room showed more depressive symptoms than their counterparts who received a normal light and dark cycle. Although the study focused on mice, the researchers believe that the results also apply to humans.

right lightWith less use of computers

and

, it is annoying that human beings rely on this light world. Therefore, completely eliminating light pollution is about equal to hitting a golf hole 250 yards away in one shot, and the chance is very small. We can only minimize the harm of light pollution. The prevention and control of

and

light pollution mainly focuses on prevention. Choose the right lamps, so as not to treat the “window of the soul”. Whether to choose the most common incandescent lamp or energy-saving fluorescent lamp is still a controversial issue. Incandescent lamp, that is, tungsten bulb, was first made by Edison in 1906. Its light is closest to natural light, that is, sunlight, in which there are relatively many long waves. Humans have evolved to adapt to this light. Fluorescent lamps (i.e. fluorescent lamps) emit discontinuous spectrum through the principle of gas discharge, with relatively more short waves. In other words, compared with incandescent lamps, fluorescent lamps are undoubtedly abnormal in their impact on the three color perception pathways.

and

are the best-selling “eye protection lamps” in the market. Whether they can protect eyesight has not been determined. First of all, in terms of luminous principle, eye protection lamp is only an upgraded version of fluorescent lamp. Many eye protection lamps take “no stroboscopic, protect eyesight” as their selling point. In fact, many eye protection lamps use high-frequency flash to create the illusion of no stroboscopic. In other words, it’s changing fast enough that you don’t notice it subjectively.

daylight lighting has high efficiency, high brightness, energy saving and long life. So far, it is still the leading light source in the global working environment.

last year, the European Scientific Committee on emerging and newly identified health risks (scenihr) pointed out in its report that the only possible risk to health caused by fluorescent lamps is ultraviolet and blue light. The harm of ultraviolet light goes without saying that blue light is caused by too short wavelength. It is reported that the skin and retina may be damaged by ultraviolet rays if working under a close-up (less than 20cm) fluorescent lamp for a long time. However, how long is long, there is no accurate answer. Perhaps it is more reliable to base on visual fatigue.

computers and televisions should be used moderately. A Japanese study found that if you face the computer screen for more than 9 hours a day for a long time, you are twice as likely to suffer from glaucoma as others, and myopic people who face the computer for a long time are at high risk of glaucoma. According to the data of who (World Health Organization), glaucoma is the second blinding factor in the world.
