You should probably eliminate the "blue light free" claim. Per results on clinicaltrials.gov, blue light conclusively does not impact sleep outcomes.

This is complex for a layperson to investigate, but you have to search for insomnia, sleep disorders, wakefulness during the day, and only studies with results. There are many uncompleted studies - it is typical for studies that have no chance of producing an interesting outcome are dropped by their investigators even when registered. However, those uncompleted studies produce many conflating results.

For example, https://clinicaltrials.gov/study/NCT02698800?tab=results specifically investigated using blue light blocking lenses compared to clear lenses. This was not blinded. The differences in all their measures were within 1 standard deviation between the groups, so the result is conclusive that (1) insomnia scores vary very widely among people as a baseline (2) if there is a real effect, it is pretty small and would require a larger sample size to measure. Of course when they measure the part where you don't know if you're looking at blue light, like when you are actually asleep, there is no difference between groups.

This is just to say that the whole blue light thing - placebo effects are real. People perceive this blue light thing as real, particularly tech people. Seed.com is successful. You can do placebos. But you should do the right thing and cut weird claims with no real evidence that are really small brained.



Even if it's not true, I like amber light at night better. No science, just "feels" better. Same with the daylight bulbs, I think they are icky at night.


Only 15 people enrolled in the cited study


I know. There are basically no studies that were run to completion. This one was. Go ahead and look for yourself. However, this study proves that if the effect exists, it is pretty small, and probably placebo. Placebo effects are real. But they affect things like surveys. Actual sleep quality did not seem to change.
