Do blue light blocking glasses actually work?

Blue light blocking glasses block like 50-90% of blue light depending on the brand, but it's not really blue light that kills your eyes - it's mainly staring at the screen without moving for hours. The real question is: does it actually help? Yeah but it's pretty marginal. What really matters is distance, screen angle, and taking breaks. When I'm working on something detailed at home, I notice a difference but there are other factors that play a way bigger role.

The thing a lot of people forget is the 20-20-20 rule: every 20 minutes, you look at something 20 feet away for 20 seconds. That really changes the game. Blue light glasses are like adding an extra layer but if you take zero breaks and your screen is glued to your face, glasses aren't gonna save you. Honestly the glasses are worth it for the peace of mind if you don't find them too expensive, but you can't see them as a magic fix. Blue light isn't the huge problem marketers want you to believe - it's just one of a thousand factors.
