Night mode is a feature found in many devices, such as smartphones and computers, that changes the screen's color scheme to reduce blue light. This mode typically uses darker backgrounds and lighter text, making it easier on the eyes in low-light conditions. By minimizing glare, night mode can help users feel more comfortable while reading or browsing at night. Using night mode can also improve sleep quality. Exposure to blue light from screens can interfere with the body's natural sleep cycle. By switching to night mode, users can enjoy their devices without disrupting their ability to fall asleep later, promoting better rest and overall well-being.
