The factors that most significantly affect eye health while using smart devices are not related to the color of the screen interface, but rather to screen brightness, contrast, duration of use, and ambient lighting conditions. Most people find reading dark text on a light background more comfortable during bright daylight, while many prefer dark mode in dimly lit rooms, where the screen appears less bright. However, doctors emphasize that there is no conclusive scientific evidence proving that dark mode reduces eye strain for all users. When using a phone in the evening, it is advisable to generally reduce screen brightness and activate night mode with warmer colors, rather than relying solely on changing the background color, as this may help reduce the impact of light on the circadian clock responsible for regulating sleep.
The optimal choice for eye comfort involves using a calm, non-glaring background, with moderate screen brightness and comfortable text contrast. Digital eye strain is not linked to the user interface color per se, but to factors such as reduced blink rate, dry eyes, glare, excessive brightness, prolonged device use, and focusing on close distances.
