How to Remove Blue Light from Your iPhone: Fast-Track Guide to Reducing Eye Strain on Your iPhone

Blue light emitted from screens, including your iPhone, can cause eye strain, disrupt your sleep, and create discomfort during nighttime use. Thankfully, Apple provides built-in solutions to reduce blue light exposure. Here’s how you can easily filter blue light and make your screen experience more comfortable and healthier.

1. Enable Night Shift:

Night Shift automatically adjusts your iPhone’s display to warmer tones, minimizing blue light in the evenings.

1. Go to Settings > Display & Brightness > Night Shift.
2. Toggle Scheduled and set your preferred times (e.g., sunset to sunrise).
3. You can also manually enable it by tapping Turn On Until Tomorrow.

2. Customize Color Filters:

For further reduction, you can customize color filters:

1. Open Settings > Accessibility > Display & Text Size > Color Filters.
2. Switch Color Filters on and select Color Tint, then adjust the intensity and hue sliders for warmer tones.

3. Use True Tone:

If your device supports it, True Tone automatically adapts the display based on ambient lighting, enhancing color warmth and comfort.

1. Go to Settings > Display & Brightness and enable True Tone.

As a designer, I’m always attentive to the visual impact of lighting—both in digital screens and in physical spaces. Just as you would layer ambient and accent lighting in an interior space for comfort and mood, optimizing your device’s display temperature is crucial for well-being. When planning the overall color ambiance of a room, similar principles apply: warm tones promote relaxation and balance harsh blue hues, whether on walls or screens.

Tips 1:

Consider enabling low light settings at night, reducing both screen glare and eye fatigue. A consistent bedtime routine that includes lower screen brightness can help improve your sleep quality.
