I actually use yellow tinted goggles after 6PM this time of year. The sunlight is so short and weak this time of year my sleep schedule gets totally messed up. When that happens in the summer I just get up in the middle of the night and work until bedtime, but that doesn't work here in December because there's not enough light during the day to get synced up.
So I try to go outdoors every day for an hour around noon, particularly if its overcast. And I wear those stupid goggles after 6PM, which is a PITA but beats lying in bed awake all night only to fall asleep at noon.
The particular pair I use (Uvex S1933X) cost only $8 and are, surprisingly, optically pretty good. There's slight distortion at the edge-of-field but they're fine in the center of the field. They don't actually block much blue light, but by looking at color swatches I've determined the cut off violet quite dramatically. When I put them on, all those irritating "blue" LEDS (which are actually violet) simply disappear. You can be looking straight at one with these puppies on and you'd never know it was lit, much less annoyingly bright. Subjectively, my eyes feel less tired too, although the lenses need frequent cleaning.
Another thing I find useful is a word processor called FocusWriter. It can edit ODT files, but it ignores all the color styling and hides all the Windows controls. The intent is to eliminate writing distractions, but I find it useful to eliminate blue-violet light exposure. I set the display background to black and the text background to amber, and those are the only colors on screen. I'd pay good money for an epaper ereader with an amber backlight. As for tablets, Amazon's Kindle App doesn't give you any nighttime-friendly options; the best is black text on sepia, but it's far too bright. Moon+ Reader is a good alternative for ePub files; Cool Reader is a GPL'd ebook reader that can be configured for comfortable nighttime reading, although it's UI isn't quite as polished as Moon+ Reader.
