a father who is now the mother of all parents, apart from an early age to live in high-rises of the city's middle-aged friends, we might as well imagine the situation 20 or 30 years ago:
Plain Village, endless fields of green Crops, villages, the smoke curl upwards;
small town in the mountains, clouds and wind around the steep mountains, lush growth of tall banyan, the Peak Tower Songqi small;
that time, said 6-over as high , large or small Has its own courtyard, the courtyard is a small playground children;
not have a computer TV, TV does not know what a computer. At that time the kids have a lot of fun, all of the outdoor game. After school, after all operating Paochuquwan because of playing at home is nothing. What hide and seek, climb trees, Niaowo out, Mo Yu lower river, to fight wild fruit … …
-time greatest wish is not to eat Shanzhenhaiwei, Dayutairou, rather it has been hungry. Coarse grains to the main staple food, dishes to its own species of vegetables, grain and vegetables all fed manure, almost no use of pesticides;
that time on the small children at home to work to help children, adults and to help share some of its power.
now the situation is worrying -
the process of industrialization has brought unprecedented economic development and wealth of material, but with enormous human cost of what they get in return:
so sharply increasing scarcity of resources;
air, food and water is The pollution from industrial waste;
the destruction of the ozone layer will lead to a wide range of skin and eye injury in the Blu-ray injury;
the greenhouse effect is a growing challenge to the survival of the human condition;
to reduce the green, the color vision goals become more and more confused. In spite of urban planning, the competent authorities at all levels to ensure that green space requirements, but in recent years, per capita public green area of the city, the campus green, green living, and so on a number of indicators of the degree of decline is very clear.
with the process of urbanization and the rapid increase in population density, residential buildings and commercial building construction-intensive, floor space is too small. Construction on the floor to set the standard pitch: the bottom of households in the winter day to ensure that there are less than an hour of light over the window (to ensure a second bedroom, three-bedroom guarantee 2). Not to mention the full window light , as a direct result of intensive building's visual space to further narrow, 5 meters away from watching the time was shorter than 5 meters, as close to the time. The reason why the few grasslands near the children, because a lot of open field of vision, a large space telescope. By contrast, urban students were significantly higher than the incidence of myopia suburban and rural areas, visual space is an important reason.
light pollution is becoming increasingly serious, large-scale outdoor use of glass walls and decorated some of the places of business unreasonable lighting, lighting is an important source of light;
computer monitors gradually replace the dominant position of printed paper, learning to become, the main course of the work of visual objects ; Brbrbr stressed that a variety of recreational facilities on the formation of color and movement of the visual impact, television, video games, computers, mobile phones and so on the screen full of amateur people living in the visual space and become worse;
stealth short-sighted culprit – Noise Noise
affect people's hearing. But you know, through the noise will be the role of the central nervous system and affect the visual organs, resulting in human visual damage. This is because the same facial features, connected to the eyes and ears , ears and eyes between the delicate internal relations.
study found that when the intensity noise of 90 dB, the retinal rod difference in the brightness of the sensitivity began to decline; when the noise of 95 dB, 40% of the pupil to expand, Shiwumohu; when the noise reached 115 decibels when Almost all eyes light brightness to reduce the adaptability of 20%, significant effect on people's vision of things around the accurate identification. As a result of more noise for a long time in environment prone to eye fatigue, eye pain, vertigo and shed tears as the object of such a phenomenon. This is in a noisy environment is not easy to concentrate on learning the work of one of the reasons why.
make noise on the eye movements of objects in the visual symmetry to balance out the response. Long-term noise in the environment, but also give rise to a neurasthenic syndrome (expressed as headaches, dizziness, tinnitus, memory, vision, and other lower). For example, flight attendants, who objects to the symmetrical balance of visual sensitivity of the Bi Changren poor response.
noise can also make the color vision, color vision abnormalities occur. High-noise environments (including the high volume of the music player) the driver of the vehicle, the incidence of traffic accidents will reduce the field of vision as a result of the increase.
due to the noise of the visual impact is mainly affected the balance of vitamins, especially vitamin B, E decreased, the noise in the environment should eat more fresh fruits and vegetables, clothes or vitamin tablets.
stealth short-sighted culprit in the second – light pollution, noise
people know that water pollution, air pollution, noise pollution on human health hazards, and to take various measures to carry out vigorous training, but did not find him a potential threat — – Optical noise pollution is serious harm to people's eyes. China's Jin Shilv as high as 60 percent of high school students, health experts believe that the visual environment is the formation of risk factors, and the eyes are not improper.
visual environment of light pollution, noise can be divided into three types: first, as the outdoor environmental pollution, such as the external walls of buildings; Second, the indoor visual pollution, such as interior decoration, interior bad light color, such as the environment; Third, the local visual pollution Such as textbooks and exercise books to paper, certain industrial products.
With the development of urban construction and scientific and technological progress, the daily life of the building and interior decoration to adopt mirror, ceramic tiles and white Fenqiang increasing the use of close-up textbooks and exercise books to read and write more and more paper-smooth, almost to himself Exposure to a weak light color, the man-made environment . According to the determination of Science: General Fenqiang white light reflection coefficient of 69% -80% of the optical glass mirror reflection coefficient of 82% -88%, in particular the smooth and Fenqiang white paper, textbooks and exercise books to the optical reflection coefficient of up to 90% Than grassland, forest or hair ornaments surface area of about 10 times, the value much higher than the human body can bear to adapt to the physical scope of the modern form the new pollution sources. The eyes of the people hurt especially, the study showed that: noise of the light pollution of the human eye's cornea and iris damage, inhibit retinal photoreceptor cells function, as caused by fatigue and declining eyesight. We look forward to the noise light pollution can cause enough attention to, as soon as possible and come up with prevention methods, so that our eyes are no longer obscure.
a large number of facts have proven that the transformation of human nature in some of their own to meet the sensual, from large to human health posed a threat to the survival, environmental protection and development of human civilization become a common issue. Let us be noted that the survival of mankind as a change in the environment, a new topic of environmental protection an urgent need to be made, and people from all walks of life need to reach a consensus contrast, that is, for visual environmental health issues.
