So you are saying there are no studies that show some people are affected by the blue light in electronic devices?

Here's just one article from an
inconsequential source. You can debate this till the cows come home but there is enough going around to show this may help some people, even if 100% does not suffer from this.
Strong words...

.
NO, I do NOT ! Read what I wrote before.
Ironically, it is Just the opposite: It was ME who claimed that there is since a long time evidence concerning
Ambient light conditions!
I only claimed that there is no evidence that the "nightshift" wil have significant impact on health or wellness - besides wellness of the shareholders, perhaps...

(because there are still millions of lemmings)
I agree: this source that you cited is absolutely irrelevant because its topic is strictly Ambient light and NOT screenlight of phones.
This article is 100% off topic.

Strong words.. But I don' t have any problem with this. In scientific discussions you don't carry always your soft gloves with you neither...
My aim is a at least a little bit logical or scientific debate with FACTS instead of marketing claims or marketing claims repeated by people not having correctly understood what they cited.
" may help" is no scientific prove at al. You admit?
Knowledge in physiology and pathophysiology is part of my profession....
BTW...
Here is the bottom line of what a therapist writes. I couldn' write it better than her:
"Of course, Night Shift only addresses part of the problem. Using your iPhone and iPad at night, especially for highly-engaging activities like video games, social networking, and messaging can also keep you awake and mess with your sleep hygiene.
Use Nightshift to help you wind down, but when it gets time for sleep, do yourself a bigger favor and just put your devices down!"
There is not much more to say about it.....
As for the text you linked:
Evidently you have not read the article properly and at least not understood its topic - which is nothing but the impact of
ambient light on humans.
You seem only to have searched by "nightshift" in acrush - as this word is mentioned once in its Original Sense, it appeared in your search machine - but they never write about screens or even this silly boy-toy with its product name abusing the inner sense of the topic of light and circadian physiology....
This article is Exactly confirming was I wrote already:
It is all about ambient light, they mention nothing but ambient light (light bulbs and LED for ambient light)!
There is no word about computers, nor screens of phones.
I propse gently to admit that you are totally wrong and this article has nothing to do with the app that apple stole from f.lux !
They offered it in the app store and one day apple blocked this little company, tok their product and claimed this as teir own "innovation.
Shame on apple!!!
. Thank you in advance for admitting that you are totally wrong.
