Does iOS blue light filter work?

As digital devices become increasingly integral to our daily lives, concerns about the potential harm of blue light exposure have become more prevalent. Apple's iOS offers a built-in solution for this issue, a feature known as "Night Shift," which acts as a blue light filter. But the question is, does this filter really work? The short answer is yes, to some extent. When you enable Night Shift on your iOS device, it changes the color temperature of your screen to a warmer hue, reducing the amount of blue light emitted. This can help alleviate eye strain and improve sleep quality, particularly if you tend to use your device in the evening or just before bedtime. However, while Night Shift does reduce the quantity of blue light your device emits, it doesn't completely eliminate it.
