众所周知,噪声可使听觉器官受到损害,轻则听力下降,重则造成病理性的永久性耳聋。然而,近年来美国、法国的科学家在研究中发现,噪声不仅损害人的听力,还严重地损害人的视力。这是因为,噪声能损害视网膜中超感光作用的杆状细胞,使杆状细胞区别光亮度的敏感性降低,识别弱光反应的时间延长,眼睛的色觉和色视也会发生异常改变,瞳孔直径会随噪声强度的升高而增大。所以,当长时间停留于噪声环境中时,易出现眼睛疲劳、眼痛眼花和视物模糊等现象。实验结果表明,当音响强度在90分贝以上时,眼底
It is well-known that noise can damage auditory organs, ranging from low hearing loss to severe permanent pathological deafness. However, in recent years, scientists in the United States and France have found in their research that noise not only damages people’s hearing but also seriously damages people’s eyesight. This is because the noise can damage the rod super-sensitive role in the retina cells, so that rod-shaped cells reduce the sensitivity of the lower brightness to identify weak reaction time, the eye color and color vision will also be abnormal changes in pupil diameter Will increase with the noise intensity increases. Therefore, when staying in a noisy environment for a long time, eye fatigue, eye ache and blurred vision are prone to occur. Experimental results show that when the sound intensity of 90 dB or more, the fundus
