M:What's that orange thing on your computer screen?

W:It's something I bought yesterday.It's a plastic sheet that blocks blue light. I have one that I use to cover my phone screen too.
W:这是我昨天买的东西,是一张挡住蓝光的塑料布。我也有一个用来遮挡手机屏幕的。
M:What do you mean by blue light?
M:你说蓝光是什么意思?
W:Blue light includes natural light, but it also includes light that isn't natural, for example, from computers, phones, televisions and other electronic devices.
W:蓝光包括自然光,但也包括非自然光,例如来自电脑、电话、电视和其他电子设备的光。
M: So blue light is harmful and that's why you want to block it.
M:所以蓝光是有害的,这就是你想阻止它的原因。
W:It isn't that simple. Blue light isn't necessarily bad for us. In fact, we need blue light during the day to be healthy.

But too much blue light, especially from electronic devices, can harm our health by weakening our vision and making it harder for us to fall asleep.

And it's the same for most of my friends.Poor sleep might be a problem for older people, but surely young people can handle late nights.
对我的大多数朋友来说也是一样,睡眠不好对老年人来说可能是个问题,但年轻人肯定能应付很晚。
W:Well, the research I've read shows that sleep is probably even more important than we thought, and that not having enough sleep can contribute to serious health problems like obesity and heart disease.
W:嗯,我读到的研究表明,睡眠可能比我们想象的更重要,睡眠不足可能会导致肥胖和心脏病等严重的健康问题。
And all the artificial blue light from electronic devices means we have to try harder to sleep well.
所有来自电子设备的人造蓝光意味着我们必须更加努力地睡好觉。
