Is dark mode good for eyes?

Dark mode, which is a feature that changes the color scheme of an interface from light to dark, has been suggested to have potential benefits for eye strain and fatigue. Some studies have shown that using dark mode can reduce the amount of glare and reflection on a screen, which can make it easier on the eyes for users who are sensitive to bright light.

Dark mode may also help to reduce the amount of blue light emitted by a screen, which can have a negative impact on sleep patterns. Blue light has been shown to suppress the production of melatonin, a hormone that regulates sleep, and can make it harder for people to fall asleep at night. By reducing the amount of blue light emitted by a screen, dark mode may help to improve sleep quality.

Additionally, when the background color of a screen is changed to dark, the brightness of the characters or symbols remains the same, which can make them more legible and easier to read, this can be especially beneficial for people with low vision or who are sensitive to bright light.

However, it's important to note that not all studies have found evidence that dark mode is better for eye strain or fatigue. It's also important to consider that the best way to reduce eye strain is to take regular breaks, reduce the amount of time spent on electronic devices, and adjust the brightness and contrast settings on the screen to a comfortable level.

There is some evidence to suggest that using a dark mode on electronic devices can be easier on the eyes, particularly in low-light environments. This is because a dark background with light text is less likely to cause glare and can reduce the amount of blue light emitted by the screen. However, more research is needed to confirm the potential benefits of dark mode for eye health. It's also important to note that individual factors such as screen brightness and text size can also affect eye strain and should be adjusted accordingly.
