  1. The original purpose is filtering blue light because it keep you awake! Yellow-ish orange-ish (like dawn) have much less effect! So, in the evening, if you have hard time sleeping, a yellow filter does help. Now, there are apps for phones/computers to filter blue and tone everything yellow/orange.
