Myopia “culprit”: noise and light pollution

Abstract: people pay attention to water pollution, air pollution, noise pollution and so on, and take measures to control it vigorously, but pay insufficient attention to noise and light pollution. As a result, the rate of various eye diseases, especially myopia, is rising rapidly., Noise and light pollution can be roughly divided into outdoor, indoor and local apparent environmental pollution., Research shows that noise and light pollution can cause damage to human cornea and iris, cause visual fatigue and visual acuity decline. The myopia rate of senior high school students in China is 60%, which is not caused by eye habits., People know the harm of water pollution, air pollution and noise pollution to human health, but they do not realize the potential threat around them – noise and light pollution, which is seriously damaging people’s eyes., People pay attention to water pollution, air pollution, noise pollution and so on, and take measures to deal with it vigorously, but pay less attention to noise and light pollution. The consequence is that the rate of various eye diseases, especially myopia, is rising rapidly. According to statistics, the myopia rate of senior high school students in China is more than 60%, ranking second in the world., Therefore, China has to invest a lot of money and manpower to deal with myopia every year, but the effect is not great. The reason is that we don’t start with improving the visual environment. Relevant health experts believe that the visual environment is the main cause of myopia, not the habit of using eyes., According to relevant experts, the noise and light pollution in the visual environment can be roughly divided into three types: first, the outdoor visual environment pollution, such as the outer wall of buildings; Second, indoor visual environment pollution, such as indoor decoration, indoor poor light and color environment, etc; Third, local environmental pollution, such as books, paper, some industrial products, etc., With the development of urban construction and the progress of science and technology, mirrors, ceramic tiles and white powder walls are increasingly used in buildings and interior decoration in daily life. Books and papers used for close reading and writing are becoming smoother and smoother. People almost put themselves in an “artificial visual environment” with “strong light and weak color”.,

noise and light pollution can be roughly divided into outdoor, indoor and local apparent environmental pollution.

studies show that noise and light pollution can damage the cornea and iris of human eyes, causing visual fatigue and vision loss. The myopia rate of senior high school students in China is 60%, which is not caused by eye habits.

and

people all know the harm of water pollution, air pollution and noise pollution to human health, but they do not realize the potential threat around them – noise and light pollution, which is seriously damaging people’s eyes.

and

people pay attention to water pollution, air pollution, noise pollution and so on, and take measures to deal with it vigorously, but pay less attention to noise and light pollution. The consequence is that the rate of various eye diseases, especially myopia, is rising rapidly. According to statistics, the myopia rate of senior high school students in China is more than 60%, ranking second in the world.

for this reason, China has to invest a lot of money and manpower to deal with myopia every year, but the effect is not great. The reason is that we don’t start from improving the visual environment. Relevant health experts believe that the visual environment is the main cause of myopia, not the habit of using eyes.

according to relevant experts, the noise and light pollution in the visual environment can be roughly divided into three types: first, the outdoor visual environment pollution, such as the outer wall of buildings; Second, indoor visual environment pollution, such as indoor decoration, indoor poor light and color environment, etc; Third, local environmental pollution, such as books, paper, some industrial products, etc.

with the development of urban construction and the progress of science and technology, mirrors, ceramic tiles and white powder walls are increasingly used in buildings and interior decoration in daily life. Books and papers used for close reading and writing are becoming smoother and smoother. People almost put themselves in an “artificial visual environment” of “strong light and weak color”.

according to scientific measurement: the light reflection coefficient of general white powder wall is 69% – 80%, and that of mirror glass is 82% – 88%. The light reflection coefficient of particularly smooth powder wall and white book paper is as high as 90%, about 10 times higher than that of grassland, forest or rough decoration. This value greatly exceeds the physiological adaptation range that the human body can bear, It constitutes a new modern pollution source. Studies have shown that noise and light pollution can damage the cornea and iris of human eyes, inhibit the function of retinal photoreceptor cells, and cause visual fatigue and visual acuity decline.
