Comment on The blue light from your phone isn't ruining your sleep

I’m curious if any part of this is that modern OLED screens are much less blue than 2012’s LED backlit screens, which affect reproducing the study.
Also, beware the tyranny of averages!
An average of 9 minutes can be some part of the population unaffected while another is massively affected.
And agree with others, unless you’re reading books, you’re probably reading email and social media before bed, and the last thing I want before sleep Is to stimulate my brain into thinking. Reading a book really helps with that.

Blue light is visible, so emitting more or less blue light Alters how colours are perceived on the display. That’s also why enabling the blue light filter makes the screen look yellow.
Screens calibrated for the same colour temperature and wilth equal brightness should emit the same amount of blue light.
