蓝光谣言起源自一个被自媒体添油加醋的研究结果。

The reason blue light is considered damaging came from a misunderstanding of research out of the University of Toledo. The researchers were specifically measuring the effect blue light has on retinal, an important chemical in the eye. While they came to the conclusion that blue light can have a negative impact on retinal, saying that blue light causes blindness is an oversimplification. The experiment measured the effect of blue light exclusively on the chemical retinal, and not how an actual eye responds to blue light. The retinal cells were not exposed to blue light the same way they would have been in a natural setting. It was a controlled environment, measuring an isolated cause and effect. In short, while scientifically sound, the research could not be directly translated to blue light’s effect on eyesight.
