I got an "eye pillow" - it's just a little bag with beans in it. I place it over my eyes when I sleep. The pressure and complete light blocking helps me reach REM sleep MUCH better and I feel much more refreshed.

"blue lights block melatonin creation". They sell lights designed to keep the room lit but not interrupt with your melatonin production thus allowing you to turn off the computer & reach sleep.
