It's a real pleasure. Honestly, it is.
Using even the dimmest display in a pitch black environment is bad because it's very hard on your eyes. It's much better to have the ambient lighting be roughly equal to the brightness of your display. If your display is brighter than your ambient light, then it's too bright and stressful to your eyes. To see an exaggeration of what I mean, just walk up to a 100W light bulb and just stare at it from about one foot away. Or, look directly into a flashlight for a while.
The color of light coming from all computer displays is not neutral. It's a cool light, meaning that it's full of blue light; way too much blue light to be exposed to right before going to sleep. Blue light suppresses the production of Melatonin and you need at least 2-3 hours for the Pineal Gland in your brain to begin producing enough Melatonin that other triggers occur that cause your whole body to prepare to go to sleep. Without that preparation, your quality of sleep suffers. It suffers far more than most people realize.
Ideally, we should be simulating the gradual dimming of the sunset in our homes before going to sleep. Instead, most of us don't change our lighting. Too many of us just keep using bright lights, watching TV, looking at computers, mobile devices, etc. Have you ever noticed how there's a blue glow on someone's face when they're using their device or their laptop? Yeah, it's not neutral, it's blue. It's roughly 6500K. Midday sunlight on a summer day can be about 5500K. A cloudy day can be even bluer than 6500K.
Why do you suppose that nature designed everything in such a way where the light from the sun becomes warmer and warmer in its color temperature as it sets? Why do you think the only natural source of light we have is fire and that the color temperature from that is extremely warm?
Have you ever noticed how some people prefer the calming effect of warm incandescent lighting vs. the energizing vivid and harsh light from fluorescent lighting?
A study was done on night driving that used a bright blue LED mounted in a car pointed at the driver's face from the side (so maybe the center of the dashboard). The idea was to see what would happen: would it act like caffeine or would it make no difference? Well, it acted like caffeine, just like sunlight. Haven't you ever noticed that you feel more awake when you look or go outside on a bright sunny day? It's not just because it's bright: it's because it's full of blue light in its spectrum. There's a ton of blue light coming from computer displays and mobile devices.
So, not only is warm light easier on our eyes, but it's not "alerting" light blue light is. This allows the body to do what it wants to at night after a long day: produce Melatonin and go to sleep. If you suppress that Melatonin from being produced, then you might still sleep, but you won't wake up feeling very refreshed.
I can speak from personal experience: when I allow my body to produce all the Melatonin that it wants, I fall asleep easier and I wake up feeling pretty good. Otherwise, it's a little harder to fall asleep and I don't feel as good when I wake up.
