How do you know if your blue blocker is working for you? Well, it's a very simple thing. You just put them on and you look at your screen and you look at something blue on your screen. And when you're looking at the blue, if you can still see the color blue, you know that that blue blocker is not blocking most of the blue light, it's only blocking a percentage of the blue light. So the deeper tints will completely block that blue tint. So that's a quick test you can do to see if your blue blocker is actually doing what it's claiming to do.
