Re: What Is The Point Of Dark Mode?

There are different reports and studies that seem to contradict
each other in part. Here are two quotes from the World Wide Web:

  In the morning, blue light helps, and during the day, bright day-
  light helps set your internal clock. Older guys have yellowed
  eyes and fewer receptors, which is why they see less blue.
  This can mess with their internal clock and, by extension,
  their sleep. Long story short, (blue and/or bright) light
  in the morning is a win, and in the evening, it's a bust.
