Parent was being rude by chastising OP with their stark, baseless claim.

Why don't you check out the dozens of studies below instead of committing selection bias?

Why don't you check out the dozens of studies below instead of committing selection bias?
"Exposure to Room Light before Bedtime Suppresses Melatonin Onset and Shortens Melatonin Duration in Humans":
* nothing about blue light
* didn't measure actual effects, just melatonin levels.
"The human circadian system adapts to prior photic history":
* nothing about blue light
* didn't measure actual effects, just melatonin levels.
So zero out of three studies in your link I looked at support the claims. As you posted these studies: Can you point me to a single study from that list that supports your claims?
Of course, that would need to be studied, and would be a more challenging study, but I think you could probably do it.

So what do we know? That excessive exposure to any kind of light at night keeps you awake?
It looks like there are several studies on the f.lux page discussing blue light specifically, but fair point that they could be cherry-picking just the studies that support their product.
f.lux and Twilight for Android (inferior but best in class) massively contributed to the reduction of my late night migraines and insomnia.
Try an experiment: code for a few hours late at night with f.lux set to match the white temperature in your room. You can do this by holding up a piece of printing paper next to your screen and matching the color.
After a few hours, change f.lux to the default temperature. Take it as bright as it goes. Then put it back at a temperature which feels comfortable and natural to you. If this is the default color temperature, let me know.
BTW, I can program on my computer with super bright neutral LEDS (my preference) lighting up the room and my monitor set to 90 percent neutral lighting, right until bed time and be asleep in 10 mins. Anecdotal evidence is just that, anecdotal.

And yes, I'm offering anecdotal data-- but I've already provided the relevant studies so this is just a bonus. In my case, the slightest thing will keep me from sleeping. My A/C was out last night and I got scarcely and hour of sleep because of the heat. I am manic depressive and sometimes I will stay up for days if I don't make extra effort to fall asleep. f.lux particularly made a very noticeable difference to me within days of adopting it.
