Blue Light Glasses | Do They Work?

The issue with blue blockers is that, first of all, there's no scientific evidence that blue blockers really work. The issue is that most blue blockers, if you look at them, they look clear or they look like they're a really light yellow tint. Right. So they only partially block blue light. So those clearer blue blockers or lighter tinted blue blockers are only blocking about anywhere from 10 to 30% of the blue light. So that's probably why the studies haven't shown that they really work, because they're only partially doing the job. So if you're going to get blue blockers, make sure you're getting blue blockers that are really blocking the blue light. So get blue blockers that are darker tinted, for example, red, or like a deep orange or amber color. Those are going to help you. Not the lighter ones.
