Since many here uses desktops I wanted to share a small tip, but first an anecdotal observation: I got my first computer at age 10-11 back in the 80s (a VIC20) and we only had a 50Hz (Europe) interlaced 21" TV as a "monitor" at that time. After using it a few months even my teacher pointed out I was getting dark circles under my eyes. My sleep was getting worst. Many years later and years in front of computer screens I also found that I had gotten delayed sleep-phase syndrome as well - this at a time CRTs was the norm. For those who say that this light is not enough to affect sleep, I would say you're wrong. But that's anecdotal..
As to the tip: here is what I did - in your color management settings, create a ICC profile which turns off almost all blue and most green. This will leave you with a darker orange color which is perfect if you need to sit late and work. This also affect all programs on your screen. You can also use tools to create ICC profiles that inverts bright colors etc.
Now you can simply toggle between your normal ICC and the dark/orange one.
Also we know that pre-teens are more than twice as sensitive to light as people in their late teens [1], and CRTs were 9300K also [2], though they were quite a bit dimmer than current ones.
