Arthur T Knackerbracket has found the following story:
[...] Councils and local governments from Paris to Brooklyn have replaced high-energy sodium bulbs (the warmer, yellow ones) with energy-saving LED bulbs (with a blue light emitting diode, which can feel harsh in comparison). As well as street lights, most of us are exposed to blue light through smartphones, computers, TVs, and in the home.
Earlier this year, the World Journal of Biological Psychiatry published a paper by a group of prominent psychiatrists that warned of the potential effects of LED lighting on mental illness.
It raised concerns about the influence of blue light on sleep, other circadian-mediated symptoms, use of digital healthcare apps and devices, and the higher sensitivity of teenagers to blue light.
[...] Studies of the impact of blue light on healthy adults show it inhibits melatonin secretion which disrupts sleep and can affect quality of life, physical and mental health and susceptibility to illness. Previous studies of sleep disorders in children and adolescents show a clear and consistent relationship between sleep disorders and frequency of digital device usage.

That is an interesting observation about sci-fi movies.
I keep pointing out that lots of these devices loaded with blue LEDs look like they are right out of the movie TRON. Which was interesting because nothing much looked like that at the time.
From other sci-fi shows you might notice that almost all futuristic weapons MUST emit a bright, usually bluish or bluish white, glow. That indicates energy and power. Never mind it would be murder (your murder) to sneak up on an enemy with one of those.
In futuristic sci-fi movies people also seem to like reading off of 1980's overhead transparency paper.
Lots of impractical stupid stuff, but people think it is all cool, possible, and should work well because it worked in the movie.
