I do use them when I can remember.
It certainly helps with keeping your eyes not get irritated and stay comfortable. Once you wear them for awhile you realize just how much more comfortable your eyes are.
I really like them and I consider them essential now.
Some people say it also helps with headaches if you get those from staring at screens all day.
I already use a blue light filter program (flux) on my screen for when I have to use it during the night, but I still use my glasses with it.
You can enable flux all the time and reduce the blue light or use the glasses and block out all of it.
They have lots of different styles too. Pretty much any common style of glasses you find can be found as blue light glasses on Amazon.
My girlfriend says I look goofy in them, but I make more money so she can't complain.
