A few years ago, about when I was a sophomore in college, I started wearing glasses with lenses that filter blue light (BluTech lenses in my case). My optometrist recommended them at the time and said they were great for people who sit at computer screens most of the day. For that, they work exceptionally well: they just subtly change the color of everything, meaning you can still see normal colors but with just a slight off-white tint, and seem to be way easier on my eyes. I ended up getting a second pair that goes over my normal contacts because I get headaches after an hour or two of being at the computer without my glasses. I can't work without them.

I haven't really noticed a particular difference when it comes to how they affect or improve my sleep or ability to fall asleep though. The most useful decision I've made to that end is to stop using my computer about an hour before I plan on going to bed. In my case, at least, it's not the blue light that seems to keep me up but how active my brain is close to bedtime. I have to give it time to unwind. I've never noticed my glasses helping with that. Your mileage may vary though.
