Why is having the option for dark mode so popular among websites and applications?
The popularity of dark mode can be attributed to several factors:

1. Reduced eye strain: The white backgrounds of many websites and applications can cause eye strain, especially in low light environments. Dark mode, on the other hand, reduces the amount of bright light emitted by the screen, making it easier on the eyes.

2. Improved visibility: Dark mode can improve visibility by providing a high contrast between text and background. This can be especially helpful for users with visual impairments or for reading in bright sunlight.

3. Aesthetics: Many users find dark mode more aesthetically pleasing than the traditional white backgrounds. This preference is often based on personal taste, but can also be influenced by current design trends.

4. Battery life: For devices with OLED screens, dark mode can help extend battery life because the pixels used for dark colors are turned off, reducing power consumption.

Overall, dark mode offers a more comfortable, visually appealing, and energy-efficient user experience, which is why it has become increasingly popular among websites and applications.
Will it run faster too?
