I am a Zeiss Customer since 1998.
With today display's that uses LED Backlight and PWM to modulate the brightness, we really get continuous headhace.
It is not only blue light, that right now we can lower by using "warm light filters" , the most important thing it is PWM (so display flickering) and temporal ditherig.
The PWM issue it is also related to Lightning in every corner of the world.
For people like me, that get higly disturbed from that, I cant live.
I can only imagine the people in my same situation saying the same things.
Imagine you wake up, look at the phone, turn on the light, go out, get the car, get lightning harras, then you go to the office, turn on the PC and the light, and the hell start.
Then you finish your office turn, then you go to the supermaket, lights are on of course, then you go into the car, in the meanwhile is night, so you have a 100% lightning harrasment when driving (is that safe? Who knows.).
You come to home, and it is night, and all lights are Turned on, you go to the bed and ask yourself, "wow i'am so tired and my head hurt... I've also some nausea.. what it is causing this"?
This happen every day to me and many other peoples!
It is not only blue light, but 60 or 70% it is due to PWM flickering from artificial lights! Even if I read "flicker free" it is not! If my eyes hurt, it flickers.
To get this bad effect Cleared and removed from our life,Me and other sensitive people, are triyng to use "e-ink" devices as PC Monitors and also Smartphones!
That changed our life! Incredibli I get can finally work 8+ hours with no problems at all!
But I do have to work on natural light coming from the sun!
Artificial light will never change cause of its principles! But Zeiss make it one time blocking UV light incredibly well... Can Zeiss make another, big, step to the future, and protect people from this? "
