Yes, the iPhone night shift mode is designed to block blue light emitted by the screen. By adjusting the color temperature of the display to a warmer tone, it reduces the exposure to blue light, which is believed to interfere with sleep patterns. Activating night shift can make the screen appear more yellowish than usual, creating a more comfortable viewing experience in low-light conditions and potentially improving sleep quality for users by minimizing blue light exposure before bedtime.
