Abstract: we all believe that noise will have an impact on hearing and psychology, but we never expected that noise will also affect vision, especially for children who are still in the stage of eye development., Now children’s myopia has become a major problem affecting their children’s eye health. Every parent doesn’t want their children to become a member of the army of myopia. It’s also a strange trick to protect their children’s eyesight. But often children still unknowingly lose their eyesight, which can worry the aspiring parents., As we all know, bad reading posture and excessive use of electronic devices will lead to children’s myopia, but the culprit of children’s myopia is not just that. However, medical research has found that noise can also affect children’s vision, which can’t help but surprise parents., We all believe that noise will have an impact on hearing and psychology, but we never expected that noise will also affect vision, especially for children who are still in the stage of eye development., The research of relevant experts shows that when noise acts on the auditory organs, it will also “spread” to the visual organs through the function of the nervous system, weakening people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness. When the sound intensity is above 90 dB, the sensitivity of rod cells in the fundus retina to distinguish light brightness begins to decline, and the time to recognize weak light response is prolonged. When the sound intensity exceeds 45 dB, 40% of people have dilated pupils, and when it reaches 115 dB, the adaptability of eyes to light brightness decreases by 20%, accompanied by the weakening of color perception., It seems that the harm of noise should not be underestimated. Parents should try to reduce the sources of noise to their children, create a good environment for their children’s life and study.,

as we all know, bad reading posture and excessive use of electronic devices will lead to children’s myopia, but the culprit of children’s myopia is not just that. However, medical research has found that noise can also affect children’s vision, which can’t help but surprise parents.
we all think that noise will have an impact on hearing and psychology, but we never thought that noise will also affect vision, especially for children who are still in the stage of eye development. The research of
and
experts shows that when noise acts on auditory organs, it will also “affect” visual organs through the action of nervous system, so as to weaken people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness. When the sound intensity is above 90 dB, the sensitivity of rod cells in the fundus retina to distinguish light brightness begins to decline, and the time to recognize weak light response is prolonged. When it exceeds 45 dB, 40% of people have dilated pupils, and when it reaches 115 dB, the adaptability of eyes to light brightness decreases by 20%, accompanied by the weakening of color perception.
and
it seems that the harm of noise can not be underestimated. Parents should try to reduce the sources of noise to their children, create a good environment for their children’s life and study.
