The statement that noise may affect the eyes and vision is correct. There is a subtle intrinsic connection between the ear and the eye, and they are both connected to the nerve center. Noise acts on the central nerve of the brain while damaging hearing, i.e., when noise is transmitted to the ears, it is transmitted to the eyes with the help of the brain’s nervous system. Long time in a noisy environment, in addition to hearing damage, for the eyes also have certain damage, such as eye pain, blurred vision, eye fatigue and eyesight tears and other phenomena. Too much sound will also lead to nerve damage, which in turn will lead to reduced and disturbed visual function. First of all, noise will cause iris sympathetic nerve stimulation, reducing the eye’s sensitivity to light, when the noise intensity at 90 decibels, the retina of the optic rod cells to distinguish the sensitivity of light began to decline, the recognition of weak light response time is also extended; when the noise at 95 decibels, 40% of people pupil dilatation, blurred vision; when the noise reaches 115 decibels, the eye’s adaptation to the brightness of light decreases by 20%. Secondly, noise will reduce the stability of vision clarity, noise at 70 decibels, vision clarity to return to a stable state takes 20 minutes, while noise at 85 decibels, it takes at least an hour or more. In addition, noise makes the eye color vision, color vision abnormalities, will make the red, blue, white field of vision narrow, affecting people’s normal work, study and life. Therefore, try to avoid being in a noisy environment for a long time, and actively eliminate and avoid noise pollution, especially for infants and children who are still in the development stage, their visual adjustment ability is not yet mature, so they should avoid the impact of noise on them to the maximum extent possible.
