I fear we'll have to speculate for a long time, then. Science doesn't seem too keen on solving this issue for us.
In the meantime I'll go by what my eyes tell me: using ambient lighting is best, strong frontlights or backlights are tiring - but if utilized should be in a warm hue and a low setting.
The worst light I have yet experienced is the frontlight on my Hisense A5 Pro. On night mode (the lowest setting) it could light up an underground dwarven kingdom. As soon as I enable the light I feel a pang of pain behind my eyes and sudden nausea; they both fade after the initial discomfort, but still. I think it's the hue of the light and screen that does it (and the fact that it just doesn't go low enough).
Onyx Nova 3 with warm light is rather pleasant, on the other hand.
I have heard that the pocketbook should have even better lighting (though most people talk about the evenness of it rather than the actual quality).
