In addition to morning light (works great!) eliminating evening blue light has hugely improved my sleep. I use these orange glasses https://www.amazon.com/Uvex-Blocking-Computer-SCT-Orange-S1933X/dp/B000USRG90/ https://www.amazon.com/Uvex-Blocking-Computer-SCT-Orange-S19... I don't wear them every evening, but whenever I need to sleep or am having sleep troubles, it solves the problem. Great for traveling too, because you can start moving your circadian clock during the flight. You can still use the phone/computer and not worry about avoiding light. I also use flux, nightshift, and Philips hue lights (set to orange at night) so that I can set and forget it. The glasses are the place to start though. They block all blue light and are super cheap, portable, and simple to try.
