A cheap way to see if too much blue light from Fluorescent lights, TVs, Computer screens or, if you work the night shift, daylight may be slowing your natural melatonin production is to make this mask from any brown soda bottle. I found Dad's Root Beer to be the right size in the 1 liter bottle. The Idea is to wear the mask in the evening to block blue light from your eyes and boost melatonin production in your body and help you feel sleepy. You can also put this on when you come home from a night shift job to trick your body into early melatonin production.
