Neither dark mode nor light mode is universally better; the best choice depends on your environment and vision, with dark mode often better in low light to reduce glare and blue light, while light mode (with reduced brightness) is generally superior in bright conditions for better readability, especially for people with astigmatism, as dark mode can cause blurriness (halation).
Features such as light mode and dark mode have been introduced to alleviate eye strain. Light mode features black text on a white background, while dark mode displays white text on a black background. The research indicates that the dark mode can reduce eye strain compared to the light mode [11].
Dark text on a light background (dark-on-light) is generally better for most people for readability, visual comfort, and accuracy of tasks that require detail. There are, however, situations and individual differences where light-on-dark (dark mode) is preferable.

Dark mode can improve readability for some users, especially those with certain visual impairments or sensitivity to bright lights. With a darker background and lighter text, the text may appear clearer and easier to read.
Exposure to blue light helps keep you alert but tends to cause eye fatigue after a while; yellow to red tints are more relaxing and may be better for long-term viewing, especially at night. Many devices allow the user to adjust the color temperature.

Red light has been shown to improve declining eyesight, with one particular study showing promise for patients diagnosed with dry age-related macular degeneration (AMD).
Unlike mini-LED displays, which emit higher levels of harmful blue light and contribute to increased eye fatigue, OLED displays emit significantly lower levels. This reduced emission makes OLED screens more comfortable for prolonged viewing, helping to minimize eye strain and support visual well-being.
Follow the 10-10-10 rule if you must spend significant time looking at any type of digital screen. Every 10 minutes, take a break and look at something 10 feet away for 10 seconds.
