Yeah, these articles are missing the big picture. I've seen too many people cite articles like this while implying effectively that sleep and wakefulness somehow is not related to lighting at all, and that's utter nonsense. Lighting is VERY relevant to sleep cycles, and there's no doubts about this anywhere legitimate. The most effective is to not ONLY use red-tint in display controls but also have dim indoor lighting AND dark red glasses (darker and redder than even the generic blue-blocking sort). And the effective is dramatic. Like really get sleepy with dim light. It's not subtle, it's about as strong as an effect can be. Studying merely the question of whether a little more or little less blue affects eye health in terms of serious diagnosable eye conditions is completely missing the point.
