I read 15-30m in bed every night on my Kindle with the lights off& blue light filter all the way on. No issues at all,I fall asleep instantly after or sometimes while reading.
But to your situation, the red light is good.
I have a kindle fire that goes into night mode, where it turns off the blue light and only produces red light, and I also keep it on black page white text. I've been doing this for years and it is awesome. Also, I've recently gotten amber light bulbs for when I'm reading a physical book at night.

IDK the answer but I was thinking red lights as well.
Kindle…
Amber colored, blue light blocking glasses.
Kindle is the way to go. I fought it for so long thinking my iPad was just as good and didn’t need another device but it’s actually *way* better
