EMDR has obvious problems, but I'm curious why you're putting blue light in the same category? It has clear and plausible physical MOA eg https://www.nature.com/articles/s42003-022-04054-9
And a note: EMDR works MUCH better than blue-light-reducing therapy. It's just that the theory for WHY it works is insane (integration of memories/thoughts across brain hemispheres is facilitated by moving eyes back and forth). It's just exposure therapy, and the "follow the light" stuff is just structuring the exposure setting. You get the same effect while doing exposure therapy while driving a car.
not necessarily - your eyelids aren't perfectly opaque
>also, circadian rhythms were proven to be unaffected even when living in a cave with no natural sunlight - so theres more to sleepiness than just light hitting your eyebaws
yeah, not disputing this. Blue light doesn't have to be the sole determinant to have an effect though
