Does Night Shift Eliminate Blue Light?: Discover the Truth About Blue Light Filters

Night Shift is a feature available on many Apple devices that automatically shifts the display colors toward the warmer end of the spectrum during evening hours. The main goal is to reduce the amount of blue light emitted from your device, which has been shown to impact sleep patterns and circadian rhythms. However, Night Shift does not completely eliminate blue light—it simply reduces it by adjusting the color temperature of your screen. Some studies suggest that while Night Shift can decrease blue light exposure, it may not be sufficient to fully prevent potential sleep disruption for everyone. If you are concerned about blue light affecting your sleep or well-being, you may want to consider additional measures, such as specialized blue-light-blocking screens or glasses, or limiting device usage before bedtime.
