Yep. And we all have different levels of sensitivity to blue light. I'm super sensitive, so if I'm doing anything on screens at night it pretty much completely shuts down my melatonin production. If I'm coding, working, reading, or watching something on a device I literally won't become sleepy. And when I do go to bed I'll lay there for a long time before I can fall asleep. Bottom line is that in order to go to sleep and get 8 hours, I have to be avoid device usage at night.
