Discussion on: The Definitive Guide To Protecting Your Eyes For Developers👀

My work glasses are both filtering blue light and they are a slightly weaker prescription than my normal outside glasses.

How this works is, normally, when your eye muscles are relaxed, your eyes focus on things far away. Focusing on things close by requires your eye muscles to do work (this is called "accommodation"). The closer they are, the more work they have to do. And focusing on something at the same distance for long periods of time causes these eye muscles to become very tired. Slightly reducing the prescription of my computer glasses means that my eyes have to accommodate less while looking at my screen.

Between the blue light filter and the weakened prescription, my eye complaints have largely been solved. I will never work without these glasses again. Best €120 I ever spent.
