為什么夜晚飛機降落時要調暗機艙里的燈？（通訊員稿）

不知您坐飛機的時候注意過沒有，如果飛機是在夜晚降落，在降落的時候，機艙的燈光都會調暗。這是基于什么原理呢？看了下面的解釋您就會明白了。
 When you fly, you may have noticed that every time
the plane takes off or lands at night the cabin crew dim the lights. The reason
is to acclimatize passenger's eyes
to darker surroundings. This isn't purely for comfort but is a valuable part of
aircraft safety. If the plane had to be evacuated in an emergency, passenger's
eyes would be better acclimatized to the darkness outside.
