How to reduce blue light with Night Shift on iPhone and iPad

Night Shift reduces blue light exposure by shifting the display’s color temperature to warmer tones. Blue light from screens can interfere with sleep patterns by affecting melatonin production. Night Shift allows users to adjust the color warmth of the screen to minimize this effect.

The feature can be scheduled to activate automatically based on a specific time or sunset and sunrise. Users can set Night Shift to turn on at night and off in the morning. The warmer tones it applies help reduce the negative effects of blue light when using devices in low-light environments.

Night Shift is fully customizable, allowing users to manually adjust the warmth level. It is primarily designed to improve eye comfort at night and support better sleep hygiene by reducing exposure to blue light.
