Any actual studies behind this thing? Glossary search through Wikipedia reveals that the only kind of actual electromagnetic radiation called blue light is... blue light. The spectrum range of visible light that looks like blue. What you get from looking at the sky during the day. "Virtually every device we use (monitors, phone screens, TVs, etc.) emits a high-frequency signal called blue light." sure makes it sounds like it's something else.
If you didn't manage to make me understand the problem i am not going to buy your solution.

o__oOur bodies follows a certain 24hr cycle called circadian rhythm. Basically the circadian rhythm tells your body when to wake up, to eat, to sleep, etc. Blue light affects that rhythm. This is problematic specially during the night when your body is supposed to be resting. Here is an article from Live Science about this http://www.livescience.com/53874-blue-light-sleep.html. You may also check the research article cited within.

o__oFrom harvards website "daylight keeps a person's internal clock aligned with the environment." If you're indoors all day and are seeking a normal 24 hour circadian rhythm, use bright lights during the day and gradually switch to red/warm lights as the sun goes down. Since blue light acts like the sun--it keeps the body from producing melatonin which is a hormone needed for sleepiness/falling asleep.
Flux uses your zip code to tell when the sun goes down near you. I use the 1 hour transition speed so I don't notice the change in screen color. Twilight on android phones does the same thing, except you set sunrise and sunset! Ex. I wake at 6am for work, so my phone turns to blue-light at 5:30AM and I wake up to the "sun" to help me become alert faster.
Light is really powerful if you use it to your advantage. Heck if I have to take a midday nap but don't have time for a full sleep cycle I sleep in the brightest room/leave the drapes open to make sure I can wake quickly after 15 minutes. But if I nap in a dark room instead, I always sleep longer than 3 hours.

abcde12345i am ignoring linked articles themselves and focusing on the studies. the first cited study found the harmful effects of plain old fluorescent light, while the second found that it can be mitigated by using a sort of full band visor. I am glad to see actual studies (instead of being told they exist) and that there is a basis to the idea of harm from such light (and other light sources, it seems), but i am still doubtful this product is as helpful as is advertised.
