Some smart phones have options to turn off blue light. I have that on auto after 7 pm.

Except it does not actually turn off the blue light.

Down yes, off no.

It is sort of like turning down the volume from 120 decibels to 100 decibels.

It is an improvement but damage is still being done.

A paper page emits no blue light. And it does not waver or blink.

Oddly it requires less concentration to read a paper page then it does the same thing on a lit screen. Which is why you will see people looking up from reading something on paper and keeping their head down when looking at a screen. They are "locked in" to what is on the screen because it takes more effort to go in and out.
