A better option, in my opinion, is to use amber-lensed goggles once the sun has gone down. These blue-blocking lenses are highly effective in reducing the effects of blue light exposure, and in most cases completely eliminate the short-wavelength radiation necessary for nocturnal melatonin suppression. (22 http://www.ncbi.nlm.nih.gov/pubmed/20030543, 23 http://www.ncbi.nlm.nih.gov/pubmed/22850476, 24 http://www.ncbi.nlm.nih.gov/pubmed/21552190) These goggles have been shown to improve sleep quality as well as mood, simply by blocking blue light and simulating physiologic darkness. The main reason I recommend using these goggles is because normal room light alone is enough to suppress melatonin at night, and unless you’re shutting off all the lights in your house when the sun sets, you’re still at risk for disrupting your melatonin-driven circadian rhythms. (25 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3047226/) While f.lux is a useful tool for your backlit devices, it’s nearly impossible to address all sources of melatonin-suppressing light in today’s world of modern technology and late-night work and entertainment habits. Amber-colored goggles are one of the only tools available to completely eliminate all blue light exposure at night, without ‘going off the grid’ and powering down your entire house after 7 PM.
