Small bit of common sense
The notion that iPhones are bad for you because they emit blue light never made sense. They're bad for you because of the content they bring in from Facebook and Twitter, not because of the color.
Now an academic is returning to sense on this subject.
According to the team, using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial to our health. Twilight is both dimmer and bluer than daylight, they say, and the body clock uses both of those features to determine the appropriate times to be asleep and awake.Not just twilight. Moonlight and starlight are blue. Our retinas favor blue so we can get around at night. A blue-dominant rectangle may pull our visual system toward night modes of thinking, hacking the dream center. If this is a meaningful effect, it's not new with iPhones. Real TV screens in the B/W era were blue. The colors on demonic "news" cable are blue to purple. When I notice one of those giant wall screens inside a house as I walk by, I'm always jolted by the strong violet. ¶ 11:39 PM
