Abstract:
Excessive smartphone use is quite common and can result in various health issues, such as migraines, eye strain, and cognitive fatigue. Dark mode, also called negative polarity, has gained popularity in recent years and several authors have suggested that it may help reduce eye strain. However, there is conflicting evidence with respect to the impact of display modes on eye strain, especially concerning smartphone use. To investigate this aspect closer, we present a study which explores the impact of smartphone display modes - specifically light and dark modes - on self-reported eye fatigue in two different ambient lighting conditions, dim and bright. We observed a significant reduction in eye fatigue with the use of dark mode in bright ambient conditions, while this effect was not significant in dim ambient lighting. Additionally, positive polarity did not significantly affect eye fatigue in either dim or bright lighting conditions. We discuss these findings in relation to existing literature.
