In my opinion, all blue light that doesn’t come from a natural source (like the Sun) is bad.
In general, blue light doesn’t harm us. But it plays a massive role in our circadian rhythm and basically “tells” our brain when to produce melatonin, and when not.
At night, when we don’t see the blue light from the Sun, we get sleepy and our body understands that it’s time for bed.
However, when we stay in front of a PC or with LED lights on, we are still exposed to the blue light and therefore our brain gets confused – Is it a day? Is it a night?!
That’s the main reason why everyone talks about the negative effect of blue light on us.
What I do – I use bulbs with more yellow light.
When it comes to my PC – I use a blue light filter – Iris.
That way I have no trouble falling asleep at night. No more lying in bed for hours and counting how much sleep I’ll get if I fall asleep in a minute.
There is no doubt that the blue light is bad for our sleep.
So my advice to you is to reduce your exposure to it – wether with blue light filter, or something else.
