How does blue light affect sleep patterns?

Almost everyone knows that blue light is bad for our health. But only a few know how exactly.

First, let’s start with a short explanation: NOT ALL blue light is bad light. The main source of blue light is our Sun and we see blue light every single day. Without being harmed. So it’s important that everyone understands in the first place that avoiding all blue light is:

  1. impossible
  2. unnecessary

However, when it comes to the blue light, that all digital devices emit, it’s not so unharmful. Basically blue light controls our circadian rhythm – it helps our brain understand when it’s a day and when it’s night.

So when no blue light passes through or eyes – our brain indicates that it’s time for sleep. And we get sleepy and go to bed.

When you sit in front of your PC till late at night, you are exposed to blue light, your body can’t understand that it’s already night and you have a hard time falling asleep after that.

This is a very simple explanation of how blue light affects our sleep.

There are a few things you can try out in order to reduce the negative effects of blue light:

  • buy blue light blocking glasses
  • buy monitor protector
  • buy a blue light filter

Blue light blocking glasses

Blue light blocking glasses can help you a lot, but I don’t like the idea that I can’t customize them.

Monitor protector

Once again, you can’t customize it, plus – once you put it on, you can’t remove it for a minute when you need to see the real colors on the screen.

Blue light filter

The best option for me – I can customize it, I can stop it whenever I want to, I can do anything I want to. I use a blue light filter called Iris.

Whether you choose glasses, protector, filter, or something else, you better hurry. Blue light is not something you can underestimate. You better start taking care of your eyes now.
