Night Mode is a feature available on many electronic devices, such as smartphones and computers, that adjusts the screen's brightness and color temperature for easier viewing in low-light conditions. It typically reduces blue light emission, which can help minimize eye strain and improve sleep quality by preventing disruption to the body's natural circadian rhythm. When activated, Night Mode often changes the display to warmer tones, making it more comfortable for users to read or browse at night. This feature can usually be scheduled to activate automatically at sunset or can be turned on manually whenever needed.
