1. Get an Anti-Glare Screen Protector
2. Blink Frequently/Splash Your Eyes with Water
3. Follow the 20/20/20 Rule
Human eyes aren’t created for prolonged staring at short distances. Rather, a human eye adapts when alternating between a long distance for a few seconds or minutes and a short distance. This is why watching something at a close distance for hours, even if it is just reading a book, forces your eyes to behave unnaturally.
