Study: Air pollution threatens the feeling of sight in children

A recent study said that air pollution does not lead to an increase in heart and lung diseases and other breathing diseases only as it is known, but it affects the feeling of sight in children. The study found that exposure to low levels of air pollution, especially nitrogen dioxide and suspended fine particles, was directly related to the extent of the brightness of the vision in children without glasses. These results not only add a new dimension to understand the crisis of environmental pollution, but rather place a serious responsibility for health and educational policies, as the evidence suggests that the lack of air quality improvement can delay or even stop the progress of a brief disease disease that is worrying for children. Talking about air pollution has always been associated with breathing problems, cardiovascular disease and early deaths, but the new in this study is to directly link pollution to eye health. The study, conducted by researchers at the British University of Birmingham, and published by the PNAS Nexus magazine, showed that the child inhaled an air that was not only affected by his chest, but that his eyes were also exposed to a series of biochemical changes that included precision infections, oxidative pressure, and lack of exposure to sunlight. The researchers believe that all these factors push the eye to change its form slightly, leading to a wrong break of light on the retina, and thus myopia. “We know for a long time that heredity and the use of screens are factors that affect the consciousness, but this study is one of the first studies that defines air pollution as an adjustable risk factor … Clean air is not only a matter of respiratory health, but also a matter that also harms the sight.” Air pollution 9 out of 10 people in the world inhale polluted air. About 7 million deaths linked annually to air pollution (external + home). Some major cities exceed more than five times the global health organization tariffs. Pollution sources: home: use of unclean energy and heating. Industrial and Agriculture: Factory exemptions and agricultural activities. Transport: Vehicle outlet. Power Stations: Especially coal. Natural sources: dust and sandstorms, waste, forest removal. The researchers relied on advanced algorithms in learning the machine to analyze the relationship between genetic and environmental factors and lifestyle, and its impact on the development of vision in children. This technique has made the separation of collapse factors possible to show the result clearly; Children living in a purest environment enjoy a better ability to see without being visible, even with genetics and hours of use of screens in mind. The study showed that at the primary stage children are most sensitive to air pollution, as the biggest improvements appeared when there is a cleaner environment, while adolescents and children with a severe palace were in advance, and the results showed that genetics were the decisive factor they had more than the environment. The author who participated in the study, Yuching Day, indicated that my restrictions in a global increase, and later could lead to serious problems such as retinal separation or glaucoma. She added: “We cannot change the child’s genes, but we can change the environment, and if we enter early before the disease is worse, we can make a real difference.” And the short view is no longer just an optical defect that can be corrected by glasses or lenses, but rather changes an urgent global health issue, according to the estimates of the World Health Organization, about half the world population, or about 5 billion people, about 5 billion people will develop, in this case by 2050. degeneration that can lead to complete vision loss. In East Asia, where the infection rate among high school students reaches more than 80%, this phenomenon is called a ‘close -looking pandemic’, which reflects the size of the challenge facing health systems around the world. The study indicates that air pollution not only affects the respiratory system, but also expands the damage to the eyes with complicated and multiple mechanisms. Microbial particles can penetrate the surface tissue that causes accurate and chronic infections, and continuous exposure to pollution increases the production of free radicals, increasing the levels of oxidative stress that harms sensitive eye cells. Pollution blocks a part of the sun’s rays needed for the growth and health of the eye, while some chemical pollutants can stimulate the secretion of materials that gradually change from the shape of the eyeball; This combination of factors makes pollution a hidden danger that threatens vision health in the long run.
