Totally false.
At the same brightness, there is the same light shining from your screen to your retina (eyes).
The main issues are:
1) Shiny screen. The eink screens are matt. Nothing to do with eink and has always been possible. Glossy surface is cheap. Micro etched glass is very expensive. Many eink use a plastic top layer for cheaper solution.
2) People simply have the brightness too high on LCD / CRT / OLED / QLED.
A shiny screen has reflections. The reflections cause eye strain (the focus muscles) and thus headaches.
A screen with whites brighter than any ambient lit object is too bright. It will hurt you differently.
Any screen that looks like paper (not copier/inkjet paper as it's unnaturally white) in the same ambient light and has no reflections will not give eye strain. A too bright front light and a shiny glass screen protector on eink will be just as bad as a typical phone/tablet.
My 4K 23" LG screen isn't tiring because the brightness is only "9", there is no lights that can reflect off it and it's a matte / not shiny finish. You can't see your face on it. The "whites" are no brighter than white print of keycaps or my eink with front light off. I only use the Frontlight if there isn't enough ambient light to read a paperback.
