Dark Mode May Not Be Kind to Your Eyes After All?
In the ongoing debate about dark mode interfaces and their impact on eye strain, a clear consensus has yet to be reached, particularly for individuals with astigmatism or myopia.
Recent studies have shown that dark mode interfaces, which reduce blue light exposure and minimize glare, can potentially alleviate eye strain in general screen use scenarios. For instance, research involving smartwatch interfaces has reported lower discomfort levels with dark mode, possibly due to reduced glare and less intense visual stimulation compared to light mode [2].
However, the evidence is not conclusive or specific to individuals with refractive errors like astigmatism or myopia. The studies did not directly examine eye conditions but rather general user comfort and cognitive performance across interface color schemes [2].
Contrasting views exist, with some findings suggesting that light mode may enhance readability and cognitive performance depending on ambient lighting and user conditions. This implies that the visual benefits might vary by context and individual visual needs [2].
At present, no direct empirical data or controlled trials specifically assessing eye strain in astigmatic or myopic individuals when using dark mode versus light mode have been identified in the current literature.
While dark mode can reduce certain visual stressors generally, empirical evidence specifically showing that dark mode worsens eye strain for users with astigmatism or myopia compared to light mode is currently insufficient or absent. Further targeted studies are needed to clarify this relationship under various environmental and individual conditions.
Accessibility remains a crucial factor in the discussion about text-background combinations. Designers must consider user diversity when implementing color schemes, ensuring that interfaces are accessible to all, including those with visual impairments.
Reading performance is better with black text on a white background due to the natural constriction of pupils, enhancing clarity and focus. However, individuals with certain visual impairments, such as astigmatism or photophobia, may find reading white text on a black background particularly challenging.
Providing options for users to select their preferred contrast settings could be the best approach for accommodating diverse needs and improving overall experience. A study demonstrated that participants performed better in tasks requiring visual acuity when using positive polarity (black text on white) compared to negative polarity (white text on black) [3].
Future research should continue exploring these dynamics as technology evolves and user interfaces become more sophisticated. Prolonged exposure to black text on white backgrounds could lead to choroidal thinning, which may increase the risk of myopia, while reading white text on black backgrounds might promote choroidal thickening, which is associated with reduced myopia risk [4].
In conclusion, the choice between dark mode and light mode involves multiple factors including visual comfort, readability, and long-term eye health. User preference plays a significant role, and providing options for users to select their preferred contrast settings could be the key to accommodating diverse needs and improving overall user experience.
