How to Turn Off Blue Light on Your Phone: 1 Minute to Reduce Eye Strain and Improve Sleep

Blue light emitted by smartphone screens can disrupt sleep patterns and cause eye strain, especially after prolonged use at night. To support better sleep and overall eye comfort, many phones have built-in blue light reduction features. Here’s how you can turn off blue light (often called “Night Mode” or “Night Shift”) across different devices:

1. iPhone (iOS): Go to Settings > Display & Brightness > Night Shift. You can manually enable it or schedule it for specific hours. Adjust the color temperature slider for your comfort.
2. Android: Navigate to Settings > Display > Night Light or Blue Light Filter. Depending on your phone brand, it may have a different name (like “Eye Comfort” or “Reading Mode”). Toggle it on and set a schedule if desired.
3. Third-party Apps: If your device doesn’t have a built-in option, consider trusted apps from the app store like f.lux or Twilight to filter blue light.

As a designer, I always consider not just the visual aesthetics of rooms, but also the impact of lighting quality in every environment. In fact, the principles of healthy lighting also apply to your digital spaces. The same care we put into AI Interior Design—balancing mood, function, and well-being—should extend to the devices we use daily. When planning both your home and your digital setup, choose features that nurture your health.

Tips 1:

To further protect your eyes, reduce screen time before bed and use “Dark Mode” options on your favorite apps and system interfaces. Adjust room lighting to complement your device screen, avoiding sharp contrasts.
