Do you use a blue light filter?

[nusound mind]

I've heard recently of the alleged negative effects of blue light on your sleep cycle and on your eyes, etc. so I'm curious how many of you use a blue light filter on your screens?

I'm giving f.lux a test out, which apparently determines where you live and adjusts the filter level of light for the daylight/sunset and night time. I like it so far, feels warmer and less harsh to look at, but maybe I'm confirmation biasing. https://www.youtube.com/watch?v=-Xj7XDT6UNk

If this is in the wrong forum I apologize, feel free to move it, it is computer config related but not audio per se although I wonder if a blue light filter would help for long audio work sessions from eye strain and so forth.

My big problem is going from the laptop screen squinting at small UIs and Preset names to trying to watch television. Not good. Blue light is bad, but what I read is if it's on while you sleep. Had a TV that would throw up a blue light when it was off. There was an option to turn it off. One I have now is red and it doesn't bother me.

I've some cheap reading glasses that filter blue light and, yeah, my eyes don't seem to feel so tired after working for a long period but, anecdotal, not scientific etc.

My Sleep Focus turns on my tiny Arturia monitors which are connected to my Sound System... which have blue LEDs. They are turned on until I wake up and I don't feel disturbed by them by any means whatsoever. I also can't fall asleep without cliqhop by somaFM running, so ones sleeping patterns might not match yours

When they first built it into Windows I tried it but I found it very annoying. I only stuck with it for a couple of weeks. But I never have trouble getting to sleep. I'll be sat in front of my computer until minutes before I hit the sack so maybe it' snot a real thing or perhaps I'm just immune to the effects or something?.

I heard the opposite that you need as much possible blue light during the day.
But then during evening and might avoid blues light.

Yeah the program I put a video of in the OP sets it up in cycles so that the screen is bluer light during the day then transitions to redder at night. You can tweak the dif. settings though to you liking.

So far I'm finding it easier on my eyes so I'll probably keep it. I think the excessive EMFs from 5G it probably a worse problem than blue light. 4G was fine, I've never needed a googleplex mb dl speeds, but I digress.

Only now? Comfortable rock it was?

Anyway, science says it's a myth.

That's what I thought... and can confirm

Animal studies should always be taken with a grain of salt, as they often do not translate directly to human behavior. And there are additional caveats to this particular paper, says Dr. Cathy Goldstein, a sleep specialist at Michigan Medicine. The researchers looked specifically at cones in the animals’ eyes, which detect color, instead of melanopsin, which senses light and is central to the issue of melatonin secretion.

They also kept light levels dim, regardless of color, which may not reflect the bright lights of electronics.

And finally, though mice are frequently used in sleep research, Goldstein notes that since the rodents are nocturnal, they may respond differently to light than humans do. Taken together, Goldstein says these conditions mean the study’s results apply only to a very narrow set of circumstances and metrics. “For this to get extrapolated to saying ‘blue light at night isn’t bad for you’ is a little bit of an extension,” Goldstein says.

Not exactly your verdict that "science says it's a myth".

Or it's just a load of bollocks, like so many other things.

Anyways I'm not an eye researcher, the question I was asking was whether people used a blue light filter. I like the blue light filter it feels less piercing on my eyes when it's on thus what made me curious if others are using one on their screens.

[chk071]

I used it for some time on my laptop, to try it out. But, I set it really subtle. The default setting was way too orange taint-y for me.

I never noticed any difference. I think what people also forget is that any kind of strain on the eye or the brain leads to fatigue.

I love using blue light filtering glasses. They’re cheap and I squint much less when I use them. I have less eye fatigue, so I’m a fan.

The glasses actually just broke, so I’m squinting again and need to order soon.

EDIT: just saw the above notes about on device filtering and I don’t find that helpful at all. I actually squint more when using something like that because it changes contrast and coloring schemes that are meant to make things easier to see.

The glasses I’m a fan of. I also use them when driving!

Have you heard of Betteridge's law of headlines? If it is worded as a question, then likely the answer is no.

That blue light thing is just media hype. Click bait, another way to get you to consume advertising space. Pseudo-science at best.

If you don't like the colour balance, then a good monitor lets you change that with some menu diving.

To make things easier on your eyes, then don't let a screen be the only source of light in the entire room.
