Did you try punching in your folk wisdom into clinicaltrials.gov?

Here's "blue light sleep":

Do you see any affect of blue light on sleep? Or do you see conclusive evidence that blue light does not affect sleep?

This reply comes off as needlessly condescending. If you have a point to make, make it, don't assign homework and ask leading questions.

I was curious where you were coming from, since I thought I had read research on this and my own experience is that changing light temperature is incredibly helpful.

The first one I clicked on showed blue-blocking lenses measurably improve sleep. I don't find the need to confirm more research at this point, given that it clearly helps me.

Blue blocking never helped me but dimming and warming the lights close to bedtime makes me sleep so much better
