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.
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.
