How to Enable Blue Light Filter on iPhone: Fast-Track Guide to Reduce Eye Strain

Enabling a blue light filter on your iPhone can help reduce eye strain, especially during nighttime use. Apple provides a built-in feature called "Night Shift," which is designed to shift the display’s colors to the warmer end of the spectrum, minimizing blue light exposure.

Here’s how to turn on the blue light filter (Night Shift) on your iPhone:

1. Open the Settings app.

2. Scroll down and tap on Display & Brightness.

3. Select Night Shift.

4. You can either manually enable it by toggling “Manually Enable Until Tomorrow”, or set a schedule for it to activate automatically during certain hours.

5. Use the slider to adjust the warmth of the display according to your comfort level.

As a designer, I’ve found that adjusting your display’s color temperature is not just beneficial to your eyes, but it can also subtly change the way you experience your personal space in low light situations. If you’re interested in planning room illumination, considering how different light sources (including screen light) affect color perception and ambience is essential. Leveraging digital tools like a room planner can help you visualize and optimize your lighting setups in every room.

Tips 1:

For tailored results, combine Night Shift with the “Dark Mode” feature in settings. This double adjustment not only reduces blue light, but also makes the interface more comfortable to look at in the evening. Remember, optimal lighting—both physical and digital—contributes significantly to interior atmosphere and wellbeing.
