Yes, night mode (often referred to as Night Shift on iOS devices) reduces blue light emitted by your device's screen. The feature adjusts the colors of your display to the warmer end of the spectrum, making the screen easier on your eyes and potentially helping you fall asleep more easily. This is especially useful during evening hours or in low-light environments to reduce strain on your eyes.
