PWM Dimming: Why Your Screen Might Be Tiring Your Eyes

Instead of smoothly lowering brightness, PWM rapidly turns the screen on and off. While the flicker is too fast to see, it can still cause:

👀 Eye strain

🤕 Headaches

🥱 Fatigue

These effects are more noticeable at low brightness levels, especially in dark environments.

✅ How to Reduce the Impact:

🔆 Keep brightness above 50% in dim light

🌙 Use Eye Comfort Mode or Night Mode

🛏️ Avoid using your phone in pitch darkness

🕶️ Try an anti-glare screen protector

🔁 Take regular screen breaks

Some OPPO phones offer a “Flicker-Free Eye Comfort” option under [Settings] > [Display & Brightness]. Turn it on if available for a more eye-friendly experience. Protect your eyes—your screen may be smarter than you think, but your comfort comes first. 👁️📱
