提起污染,人们马上就会联想到浓烟、污水、噪声……却往往忽视另一种对人类健康造成潜在威胁的公害,这就是光污染。现代舞厅中的激光就是一种常见的可见光污染。舞厅激光的特点是高速变幻,令人眼花缭乱,而且光线强烈耀目。科学家们指出,舞厅中的激光对人的眼睛可产生有害影响。据英国某杂志报道;联邦德国卫生局专家于尔根·伯恩哈德教授认为,迪斯科舞厅里的激光会损害人的眼睛,密集的光束通过眼睛的晶体再次集中后,光的温度可达到70℃左右,如果直接射在视觉中心点,视网膜就会遭损,使视力下降。慕尼黑大学医学院的教授检查了11个迪斯科舞厅激光设备,发现大多数情况下都超过了激光辐
Pollution, people will immediately think of smoke, sewage, noise ... but often overlook another potential threat to human health, public nuisance, which is light pollution. The laser in modern ballroom is a kind of common visible light pollution. Ballroom laser is characterized by high speed changes, dazzling, and intense light. Scientists point out that the laser in the ballroom can have a detrimental effect on human eyes. According to a British magazine reported; Federal German Health Board expert Professor Jürgen Bernhard believes that the discotheque laser will damage the human eye, intensive light through the eyes of the crystal concentration once again, the light temperature can reach 70 ℃ or so, if the direct shot in the visual center, the retina will be damaged, so that vision loss. Professors at the University of Munich School of Medicine examined 11 discotheque laser equipment and found that in most cases they exceeded laser radiance
