I keep it short as there are so many study's and other video's.
Blue light is needed to create somekind of white,how you react on it is for each person different.
And Yes if you get all blue light out then there is nothing to filter but then again,don't call it al filter ! You just turn it off.. so when I go to bed and shut down all lights I filter it ??
Study one says that even dim light can create some effect,study 2 and many others say it don't.
We can all look and search for a study that gives us right.
In our local campains Kobo say that they filter the blue light.
In practice, when you could (because no one knows really if you where able to close the blue ,only Kobo and they don't respond) get out all blue light IMHO you can better turn of the light because it gives a filthy color.
So maybe some people will adjust the color, but I doubt they shut down all blue light so they will still get exposed to it.
I sit from 8.30 AM for work at my led monitor until 7.30 PM , I do have special glasses but don't use them much because the screen get a strange color when the blue light is filtered.
Then between 7.30 PM and bedtime, i do spend some additional time at the computer.
Mostly at 11.30 I go to bed and read about 45 minutes at the Glo HD and then I am so sleepy that I close my eyes and sleep without any problem..
I think next month they will discover that green light is dangerous too..
For as far as I understand Kobo added some leds between the original leds that can change color, not all of them.
So even when you change color, you would not change the color of all the leds only the "special ones" but again.. we have to guess this.
