  The amount of blue light emitted by an LCD depends on the backlight used. Some brands advertise low blue light. You could even build an LCD with zero blue light emission if you wanted to, at the cost of being unable to display blue. And even with a conventional backlight, you can reduce the blue light to very low levels in software, e.g.: https://en.wikipedia.org/wiki/Redshift_(software) https://en.wikipedia.org/wiki/Redshift_(software) E-ink reflects light over a broad spectrum, so the amount of blue depends on the amount of blue it's illuminated with. It can be higher than the LCD in some conditions.

    not disagreeing, but you can't chose the display of the laptop most of the times. Besides, in the last 2 years people reported many more cases of eye strain and blurred vision (at least in my country), because "home" is not really the best work environment for 95% of the people. There's a reason why offices are always well illuminated. e-inks are usually used with lights turned off and when ate not I use the red light because it's better for reading.
