Full answer body

Expanded summary

Scientific studies and industry professionals suggest that OLED screens, which use lower-frequency PWM for dimming, can lead to eye discomfort, headaches, and dizziness in individuals sensitive to flicker. Research indicates that approximately 10-30% of users exhibit heightened sensitivity to screen flicker, reporting symptoms like headaches and eye strain when using PWM-controlled OLED displays. While there is no direct relationship between OLED screens and eye harm, the flicker from OLED screens can cause issues in sensitive individuals, particularly at low brightness levels. Practical advice includes using extra-dim features or toggling DC dimming to reduce eye strain.
