Easy to ignore the LED light pollution damage in the end how much?

Red network, talking about water pollution, air pollution, soil pollution, we can cite a lot of examples, but when it comes to light pollution, many people can not touch the mind. In fact, with the continuous development and utilization of the modern society, the light in the benefit of mankind, but also brought some negative effects, the harm of light pollution around us.

"Light" to the eyes of the disaster

Xie Meifen in Xiangtan Central Hospital for more than 20 years of work, recently, a pair of children came to visit her mother impressed, because the mother and the eyes of the two people have problems. Mother is mainly due to overuse of eye strain, but the child was only more than and 10 years old, usually watching TV, reading are also very attention to eye health, why is there a vision problem? Then the mother recalled, she gave his son a child afraid of the winter cold, often two to the son of Yuba heating, as everyone knows, it is the light burns Yuba the eyes of a child.

Doctor Xie Meifen told us that in strong light irradiation, extra light entering the eye, beyond the normal range of contraction of pupil blocking the light, long under the influence of great damage to the eyes. In addition to visible light, the light also contains ultraviolet, infrared, radiation, etc., and these light will cause damage to the eyes. Because the child's eyes are more vulnerable, more sensitive to the perception of light, it is more vulnerable to injury.

The damage caused by the strong light to the eye mainly includes macular disease, refractive error, glaucoma, cataract, etc.. Elderly people with high levels of ultraviolet radiation are more likely to suffer from cataract, which is the most typical example of light pollution.

Light pollution hazard

Recently, Ms. Xie, who lives in the name of the house to reflect to us, her bedroom window is facing a large hotel LED advertising screen. But recently the display is a bright light night, pull the curtains after the room is lit, so Ms. Xie sleep a serious decline in quality. She found the Internet search, he was in the light pollution in the environment.

Municipal Quality Supervision Bureau Metrology Division is responsible for some units of optical instruments (such as laser, X light, illuminance meter, etc.) calibration. The person in charge of the Department Peng Jiwen told us that the irrational use of light will bring light pollution. The glass curtain wall reflected glare is brought about by the "white pollution", the lighting brightness is too large is artificial daylight; color light entertainment constitutes a "light pollution", in addition to the impact on people's eyes, rest, skin, can also produce other hazards.

City Environmental Protection Bureau experts, night lights will disrupt the rhythm of plant physiology, hinder their normal development, growth and reproduction. Especially the willows and other light sensitive plants, suffered long time light at night, stem lesions, will die; the reflective glass curtain wall building in the city caused by the refraction of light, can make the person produces dizziness, temporary blindness, occasionally causing traffic accidents. Due to the construction of the city, such as glass, porcelain, etc., the city is difficult to absorb sunlight, which has become one of the reasons for the "heat island effect".

Light pollution easily ignored by the public

We learned from the Municipal Environmental Protection Bureau, in recent years, environmental protection hotline also received light pollution complaints, but compared with water, air and noise pollution complaints, solid waste and other types of light pollution complaints was "lonely", in the thousands of complaints accounted for only a few. Mainly in the construction of the intersection, the construction of the camp, and other cities around the downtown area, the main reason for the complaint is because the mall LED large advertising screen light is too bright, affecting the rest of the night.

We interviewed a number of people, found that they do not know much about light pollution. The Central Hospital of general medical department of Fu sang doctor said that light pollution will indeed bring a lot of health problems, such as dry eyes, swelling or pain, also affect sleep and normal life, causing disorder of hormone secretion in the human body. But few people will relate these symptoms to light pollution.

Fu sang told us, in fact, a lot of light pollution hazards can be avoided, we can take effective measures to protect. Such as the installation of thick curtains, go out wearing a reliable quality of the polarizer, etc., to minimize the impact of light pollution on life, health.

Need to improve departmental supervision

Many of the hazards of light pollution, it is difficult to solve the problem alone, so it is very important to strengthen the supervision of the department.

The Municipal Environmental Protection Bureau law xuanke official told us, "environmental protection law" the lack of clear provisions on the prevention of light pollution, so even if they received complaints, it is difficult to carry out effective treatment. He said that local light pollution may also be controlled by the removal of light sources to prevent and control, but to prevent and control light pollution, it is necessary to improve local and overall planning.

Municipal environmental protection monitoring station staff recommendations, can be considered in the future construction of light pollution monitoring platform, regular sky brightness, ground brightness, illumination and other indicators of different areas of the city were evaluated, record city light environment development process, standards and norms based on light pollution control. At the same time, the legislation of light pollution should be established on the basis of perfecting the evaluation system of light pollution, and the evaluation and judgment of the degree of light pollution can provide sufficient basis for legislation.
