若你只看到光的某一频率，你会感到恍惚，然后眼睛会努力适应这一体验，而在这一过程中，不同的色调就会产生。
When you see just one frequency of light, it is disturbing and the eye tries to accommodate itself to the experience and in the process, different tones appear that do not exist in the place.
这就叫做“暗光适应”。你的眼睛花上一个钟头就可以完全适应光线暗淡的环境。
This is called "dark adaptation" and it takes your eye up to an hour to become fully adapted to seeing in low light conditions.
并且LED的尺寸也在改进从而适应更强电流产生更多光。
There has also been progress in scaling up the size of LEDs, so that they can be driven at higher currents and generate more light.
