WishNewFish September 29, 2017 Share September 29, 2017 On a completely different note, Blue light is disruptive to human circadian rhythm. Looking at deep blue light at night can cause insomnia. https://www.health.harvard.edu/staying-healthy/blue-light-has-a-dark-side Link to comment Share on other sites More sharing options...
Origami September 29, 2017 Share September 29, 2017 Thanks, Molcott. I'd been designing hardware for about a decade when commercially viable blue LEDs were first announced (soon followed by white ones). Looking around today, it's had a huge impact on everyday life. One that I, until now, had never thought about much. Great story. Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
