有人做过试验,当噪音强度在90分贝时,视网膜中视杆细胞区别光度亮度的敏感性开始下降;当噪音在95分贝时,五分之二的人瞳孔开始扩大,视物模糊,当噪音达到115分贝时,几乎所有的人眼球对光亮度的适应都有不同程度的衰减。因此,长时间处于噪音环境中容易发生眼疲劳、眼痛、眼花和视物流泪等眼损伤现象。噪音还会使色觉、色视野发生异常。调查显示,在接受稳态噪音的80名工人中,出现红蓝白三色视野缩小者高 Someone did the test, when the noise intensity at 90 decibels, rod photoreceptors in the retina differences in sensitivity began to decline; when the noise at 95 decibels, two-fifths of the pupil began to expand, blurred vision, when the noise reached 115 decibels, almost all of the eyeballs have different degrees of adaptation to the brightness attenuation. Therefore, long time in a noisy environment prone to eye fatigue, eye pain, vertigo and visual material tears and other eye injuries. Noise also makes color vision, color vision abnormalities. According to the survey, among the 80 workers who accepted steady-state noise, there was a high red-white-white-tipped view
