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.

藍(lán)光真的能影響你的健康嗎？睡覺(jué)之前的藍(lán)光能讓你更加難以入眠,手機(jī)，電腦和電視都能發(fā)出大量的藍(lán)光。但是如果你認(rèn)為藍(lán)光是影響你睡眠和眼睛健康的主要問(wèn)題的話，那就該換個(gè)角度思考了。

一位研究人員說(shuō)藍(lán)光是太陽(yáng)光的部分，你的眼睛一直出處于太陽(yáng)光下，但是你眼睛完好無(wú)損。對(duì)小白鼠的實(shí)驗(yàn)發(fā)現(xiàn)藍(lán)光對(duì)眼睛有害，但老鼠是夜行動(dòng)物，他們的眼睛不同于我們的眼睛，從某種意義來(lái)說(shuō)，我們的眼睛能自我保護(hù)。

加上更多的保護(hù)可能也有幫助，你可以買藍(lán)光過(guò)濾眼鏡來(lái)遮擋藍(lán)光，但研究人員指出，這種方法只會(huì)浪費(fèi)你的錢，要把手機(jī)離你的臉遠(yuǎn)一點(diǎn)，與戴藍(lán)光過(guò)濾眼鏡的效果一樣。

如果你擔(dān)心有你的眼睛健康和準(zhǔn)時(shí)睡眠時(shí)間，你已經(jīng)知道做些什么了：就前十遠(yuǎn)離屏幕。讀一本書(shū)或找點(diǎn)其他事情做。你要使用屏幕時(shí)，每20分鐘休息20秒。
