Software aid for late night (angband) sessions

[Pete Mack]

I installed this blue-light filter a few weeks ago, to reduce the impact of computer monitor glare on sleep cycles. I can really tell the difference; getting to sleep earlier and more reliably.

Strongly recommended for late night computer use (though not for angband so much, since the screen is mostly black.) If you do use it with angband, you may need a different color for dark blue, since the default is hard to see with the blue filter enabled.

I stand by f.lux, it's great. After long enough using it, it's just normal, and having it off is way too bright/blue at night

You can change how orange it makes the screen too (and it's a HUGE range), and temporarily turn it off if you need to.

[Pete Mack]

Yeah the first few nights i'd be turning it off regularly, because the color looked a bit too red. Now when I turn it off, the color looks too blue.

I've heard about this type of thing, but is there actual good evidence for its efficacy?

[Pete Mack]

For this app in particular? I don't know. For blue light in general? Yes. There are a lot of studies. Here's a review paper

Edit: the reason I posted this here is because of somewhat frequent stories about late night angband games. If you are switching to a web browser while playing, this app is may help.

Interesting. (Haven't read through it yet, but I'm always skeptical of these things -- I find that it's generally a good "posture" to adopt.)

[Pete Mack]

The evidence as reported is pretty strong. Or you can just try it and decide for yourself.

I'm going to consider using this at some point. What settings have you all used for f.lux?

[krazyhades]

I just make sure my slider is unlocked to the full range (by default it limits the range to be less aggressive in its tinting) and then tweak it at need. At this very moment I have it to 3400k but that's not a fixed value for me. Forewarning: the angband dark blue can sometimes be very hard to see since f.lux is filters out most of your blue light.

[Pete Mack]

Initially I set it to 3700 or so, because 3400 is pretty red. After I got used to it I turned it down to 3400. But then I realized I was setting the screen brightness higher to compensate, and turned it back to 3700. So: 3700-3800.

I've been using f.lux for over a week. My main setting is 4200K Although I'm not sleeping earlier, the f.lux seems to be doing another favor by reducing glare. That's still good.

[Pete Mack]

It technically can't affect glare: that's from reflected light. It does reduce eyestrain in a dim environment, I agree.
And yes, you will need to edit the dark blue color if you are playing *bands. Blue on black is already hard to see without making it even harder worse.

[HugoVirtuoso]

That's what I meant -- the lower color temperature reduces eye strain.
