I sort of figured this out by staring at a number of large computer monitors at night - with blue light filtering - and still finding myself unable to sleep. Yet the article mentions that overall light intensity is also important. Now at night I turn off most of my lights, dim the ones I keep on, turn on a lot of light only as needed, and use a laptop/phone/e-reader. Such an arrangement also I think leads to you naturally engaging in less stimulating things at night. I'm trying to replace my light fixtures with ones that aren't as insanely bright and blue as a lot of modern LED light fixtures are. I'm also trying starting off my mornings my staring at intimidating arrays of monitors while shining a very bright SAD lamp into my face with my window blinds drawn. I can't really tell if things are working yet, or if it's just a placebo, but I feel sleepier.
