Does the blue light actually influence your health？Blue light before bedtime can make it harder to sleep，And screens on phones,computers and television give out a lot of blue light.This is all true.But if you think blue light as main problem influencing your sleep or your eye health,It's time to think in another way.

A researcher says that blue light is part of sunlight and your eyes are under the sunshine all the time .You are fine. There are studies in mice that have found blue light can be bad for the eyes, but mice are nocturnal creatures whose eyes are different from ours.In a sence our eyes can protect themselves.

However, adding more protection isn't likely to help.You can buy blue _blocking glasses to stop the blue light ,but the research points out that way will waste your money. You could get the same effect just by holding your phone far from your face.

If you are worried about your eye health or your ability to get to sleep on time, you already know what to do: put the screens away at bedtime. Read a book or find something else to do. While you are using screens, take a twenty second break every 20 minutes.

蓝光真的能影响你的健康吗？睡觉之前的蓝光能让你更加难以入眠,手机，电脑和电视都能发出大量的蓝光。但是如果你认为蓝光是影响你睡眠和眼睛健康的主要问题的话，那就该换个角度思考了。

一位研究人员说蓝光是太阳光的部分，你的眼睛一直出处于太阳光下，但是你眼睛完好无损。对小白鼠的实验发现蓝光对眼睛有害，但老鼠是夜行动物，他们的眼睛不同于我们的眼睛，从某种意义来说，我们的眼睛能自我保护。

加上更多的保护可能也有帮助，你可以买蓝光过滤眼镜来遮挡蓝光，但研究人员指出，这种方法只会浪费你的钱，要把手机离你的脸远一点，与戴蓝光过滤眼镜的效果一样。

如果你担心有你的眼睛健康和准时睡眠时间，你已经知道做些什么了：就前十远离屏幕。读一本书或找点其他事情做。你要使用屏幕时，每20分钟休息20秒。
