To be clear, I was not calling bullshit - I experimented with UVEX blue-blocking glasses, and so a marked difference in "natural" sleep times. Similarly with early morning Vitamin D, and exercise, and I am not the only one.

However, I am not aware of any reasonably objective evaluation of these claims, so I don't consider them "truth" or "science" - they are anecdata, which might be interesting, but not science.

There is no direct evidence but proxy evidence.

Atleast for me, using a red-tint filter on a phone or computer screen helps a lot with eye fatigue and afaik also with sleeping as I tend to be more tired when waking up after not using such a filter.

Additionally, I'm fairly certain that there have been numerous studies that found that the color of light heavily affects the circadian rythm, especially the blue component, not only in humans.

By proxy any blue-light filter should have similar effects. And by proxy of that a blue-light filtering pair of glasses should too.
