Study finds OLED, LCD screens cause similar eye fatigue

A new study indicates no significant difference in eye fatigue between OLED and LCD screens after prolonged use, challenging the common belief that OLED is more harmful. The research, conducted in a lab setting, involved participants viewing screens for 35 minutes under varying refresh rates and dimming methods, with no notable difference in subjective fatigue scores or objective eye strain measurements. Experts emphasize that screen technology is only one factor in eye fatigue. Factors like screen brightness, ambient lighting, and individual viewing habits play a more significant role in eye strain. Experts recommend considering DC-dimming LCDs or high-frequency PWM OLEDs for extended use, and practicing the 20-20-20 rule.
