This study mentions blue light as from smartphones as a problem. My phone has a blue light filter which I have on all the time. Linux gnome desktop also has one for late night coding sessions.

Turned it on just now, thanks for sharing I didn't know that existed.

  For those not using Gnome, gtk-redshift is great if using X11. I use it on cinnamon all the time.

    There is also a convenient Redshift applet for Plasma. Its package is called plasma-applet-redshift-control in Debian.

These things are incredible. I used to turn it on for my eyes, but i noticed that when on my laptop in bed, without it on, i wont feel tired at all. I turn nightshift on and suddenly i feel sleepy :)

  Not only that, try to switch it on and off a couple of times. You'll see that when the blue light is ON after having used the blue filter for like a couple of seconds, you'll feel like someone punching your eyes! It's almost like having a lamp in your face all the time in the night - of course you can't sleep! We just got used to it. Now thankfully someone has implemented such filters.

Additionally Windows 10 has also introduced this option in Display Settings -> nightlight

  ChromeOS supports this as well.

f.lux is awesome - it's been around for many years, and is free. Available for Linux, Mac, iOS, Android, and Windows! https://justgetflux.com/ https://justgetflux.com/

  I use f.lux on Windows and it awesome. Also, redshift is available for at least Linux, the BSDs, and an experimental version for Windows.

  SunsetScreen is good if you live at an extreme latitude. Don't know if this has been addressed in recent updates, last time I used flux it wanted to start dimming my screen at 18.00 in the winter and close to midnight in the summer. At the time, f.lux's devs seemed completely opposed to any kind of adjustable schedule for people who cannot follow the sun.

  iOS and OS X has Night Shift, which is native implementation of the same idea.

You can solve this globally by getting eye glasses that filter blue light as long as you're not doing any sort of colour-sensitive work. After a day or two you don't notice the colour difference anymore.

  If everyone wears them you should to when doing color-sensitive work. Granted that's a mighty big if.

  I came here to say the same thing, ever since I've gotten a new pair of glasses with blue filter coating, I don't get that match eye strain and headaches in the office. you get used to them immediately and can see the difference in many places you wouldn't expect.

  I had my glasses with the blue light filter lenses for a couple of years, the problem is that I wear it all the time and I got used with it very easy, but the entire world was skewed. Also the monitors were looking yellow, an ugly kind of yellow, I switched back to regular lenses and I am perfectly fine with it.

  How do you personally find the balance between blue light keeping you awake verse mental stimulation keeping you awake? I don't do any math or coding in the ~2 hours before bed, as a general rule.
  - nucleardog 7y ago
    I got the filtered glasses mostly because of the purported benefits regarding eye strain, so I hadn't put a lot of thought into trying to compare the effects on sleep. Definitely wouldn't discount blue light having some effect, but I'm totally on the same page as you here regarding limiting stimulation and I'd have a hard time believing anyone that claimed lighting had anything even close to the effect that other habits did. Had trouble sleeping for years. Made my bed and bedroom a place for sleep and only sleep. When I go to bed the phone goes on do not disturb, there's no computer/TV/etc in the room at all and no clock (I can't look at a clock without thinking of all the things I have to do!). I just get into bed and lay there until I'm asleep. Some days I'll try and read a little, but I find these days that I don't make it very far at all before I'm asleep. Haven't even had to go as far as limiting activities before bed or anything all that much. At some point my body and brain got conditioned to sleep when in bed, so it's usually a pretty painless process now.

I guess this varies from person to person. Maybe it is a problem if you have trouble sleeping anyway, but as far as I'm concerned, I guess the blue light just keeps me awake as long as I need to finish whatever I'm doing, after that I usually have no trouble at all going to sleep. When using a blue-light-reduced "night mode" however, I find I can barely keep my eyes open...

There are special Gunnar glasses that seem to work well by reflecting blue light - they completely eliminated any eye strain I felt while coding in the night. Coupled with natural light lamp, it's a great combo for a winter coder.
