On my laptop and phone (I alternate looking at both before bed) I have an "evening" setting. So instead of buying a pair of sunset-tinted glasses, which Murray recommended, I amped up the orange hue on my devices instead of just turning down the brightness feature.
The orange tint is meant to block all blue light, thus not inhibiting melatonin production, so that our brains don't tell our bodies to stay awake all night.
I'm not sure what it was about the yellow-orange tint but for some reason I couldn't stand to look at it. Not in an eye-sensitivity way but in that I really didn't like the look of it.
So if you're not as picky about aesthetics as I am, then feel free to grab the glasses.
