Good golly Miss Molly -- depression seems to be quite common within our ranks.
Yesterday, I had to have an eye exam to please the State of Minnesota so that I can drive the two or three thousand miles a year I put on my relic VW. On a whim, I asked the optometrist if there was anything to the "myth" of blue light impacting sleep.
Wow! He went from Mr. Quiet Conservative to Son-of-a Preacher-Man in a nano-second. The next ten minutes was a steady stream of melatonin-talk.
Bottom-line: The National Sleep Foundation recommends that we avoid all blue light (TV, tablets, etc.) for two to three hours before going to sleep. Although their study focused on teenagers, it seemingly would apply o any age. https://www.sleepfoundation.org/articles/light-sleep-school-...
It struck me that the average BC reader/author probably does their online reading and computer-aided writing primarily right before they go to bed.
What are your thoughts?

Well, technically, almost all
Well, technically, almost all LED lighting is 'blue light'. They simply put a phosphor in front of the emitter to change the colour. Fluorescent lights work the same way, taking UV and shifting it downwards.
So if you wanted to avoid everything for three hours before sleeping, you'd have to turn off everything except incandescent bulbs.
Either that, or you're fine with the LED's because of the phosphor. It's hard to say.
I'll get a life when it's proven and substantiated to be better than what I'm currently experiencing.
It's a matter of how much
Even incandescent lamps emit blue light. They have a lower color temperature, so emit comparatively more on the red end.
Most fluorescent and LED lamps emit relatively more blue. Most. You can get different color temperatures if you look for them.
We have LED reading lamps that have a lower color temperature (which are called 'warm white.') The ceiling lamps are a more sunlight color. They are good for waking up in the morning.
And yes, there are apps that reduce the amount of blue light. We haven't tried any, though.
Windows 10 has a blue light setting
Windows 10 and newer phones and tablets (Android for sure) have a setting to turn off blue light.
Blue Light
I looked at my settings in Win10 and I think it says that only the night light has blue light. Mine is OFF. I usually put the thing to sleep at night because I sleep about 6 feet from it. Often I just shut the whole thing off, if the HD is chirping too much.
Blue light filtering in the evening/night
Windows 10, many Linuxes and current mobile phones / tablets have a setting do activate a blue light filter during the night.
My Linux PC here shows a rmore and more yellow/red screen when it gets dark outside.
Of course this can be manually disabled if you want to look at clothes in an online shop ;)

According to My Optometrist
My optometrist said that there have not been definitive studies to prove that the filters and glasses that filter have not been proven to be effective.
Just sayin'.
