OLED is what this type of technology is trying to avoid - active light sources that have multiple undesirable characteristics. OLED in particular has a lot of deep blue light, which is damaging to human eyes. You know all those gaming glasses and monitor modes that removes blue from the spectrum? That's why they are there. OLED is far worse than LCD for this problem. There is no health regulation on the market yet where I am for blue light emission, so you just have to deal with it.
What are you talking about? If you look at the spectrum of LED vs OLED, LED has far more intense Blue than OLED. You are confusing OLED having higher color gamut (capable of more blues) with intensity.
Not to mention OLED has each color separate, so when you remove blue, it is truly gone. In comparison, for LCD the blue is still there just gets filtered but it isn't perfect and can bleed.
This shouldn't of course be confused with LG's WOLEDs which use only white OLED back-lighting has high blue just like LEDs. But that is due to LG's choice to use WOLED backlighting, true OLED that you find on tablets and phones produces much more natural light with less intense Blue's. So lets not blame the OLED technology as a whole.

Passive e-ink displays can't solve all problems and especially the main ones associated with prolonged stare at fixed distance, short distance objects. Lots of Chinese kids today are myopic from prolonged reading.
Well, it would be nice if large e-ink prices drop, they are quite expensive due to tight patents and low economies of scale. There is also a competitor with that new TCL technology that uses light reflection, the NXTPAPER though I havent seen how good it is but it has potential.
