Sure, I wear blue blockers 2 hours before bed (~11pm) and I use blue LEDs that shine in my eyes from a distance while I'm reading for an hour after I get up at (7am). I don't use an alarm clock and I can't drink caffeine (Graves). I found the blue blockers at night to be more effective for regulating sleep than the blue light in the morning. You can get blue blockers for $5 on Amazon. Highly recommended.
