How to Turn Off Blue Light on iPhone: 1 Minute to Reducing Eye Strain on Your iPhone

Blue light emitted from your iPhone screen can interfere with your sleep and cause eye strain, especially at night. Luckily, Apple offers various settings to reduce blue light exposure. The primary feature is called "Night Shift," which adjusts your screen’s color temperature to warmer tones. To enable or schedule Night Shift, follow these steps:

1. Open Settings on your iPhone.
2. Scroll down and tap Display & Brightness.
3. Select Night Shift.
4. To manually activate, tap Manually Enable Until Tomorrow.
5. To schedule Night Shift, set your preferred timeframe using Scheduled and adjust the Color Temperature slider for your comfort.

Alternatively, you can access Night Shift quickly via the Control Center by long-pressing on the brightness slider and toggling Night Shift on or off. This simple adjustment makes late-night reading or design browsing much easier on your eyes.

As an interior designer, I often review project photos or sketches on my phone well into the evening. Minimizing blue light isn’t just about comfort—it helps maintain a restful environment for creativity. For those designing spaces with technology in mind, consider how AI-powered interior design tools can inspire smart, serene rooms that support overall well-being, blending digital convenience with thoughtful ambience.

Tips 1:

If you spend extended hours viewing detailed images or plans on your iPhone, pair Night Shift with lowering screen brightness and enabling "True Tone" for even more natural color reproduction at night.
