噪声会损害视力!因为噪声能使人的视杆细胞区别光亮度的敏感性降低,识别弱光反应的时间延长;瞳孔直径会随噪声强度的升高而增大。噪声在95分贝时,瞳孔增大者占40％,噪声达到115分贝时,眼睛对光亮度的适应性会降低20％以上。在噪声环境里,眼睛容易疲劳,甚至发生眼痛,眼花和流泪现象。这些眼睛异常改变现象,在人脱离噪声环境后,一般在20分钟到两小时以后,眼睛可以恢复到正常状态。
Noise can impair vision! Because noise reduces the sensitivity of human rod photometry to differentiating lightness, the longer the time to recognize poor light response, the pupil diameter increases with increasing noise intensity. When the noise is 95 dB, the pupil increases by 40%, and when the noise reaches 115 dB, the adaptability of the eye to the brightness will be reduced by more than 20%. In a noisy environment, the eyes are prone to fatigue, and even ocular pains, vertigo and tears occur. These abnormal changes in the eye phenomenon, the people from the noise environment, usually 20 minutes to two hours later, the eyes can be restored to normal.
