How to Stop Blue Light on iPhone: 1 Minute to Reduce Eye Strain and Sleep Better

Blue light emitted from screens can cause eye strain and disrupt sleep patterns, especially after prolonged iPhone use. Fortunately, Apple provides effective tools to reduce blue light and make your device more comfortable to use—in particular, the "Night Shift" feature. Here's how you can minimize blue light exposure on your iPhone:

1. Enable Night Shift: Go to Settings > Display & Brightness > Night Shift. Here, you can schedule times for Night Shift to automatically shift the colors of your display to the warmer end of the spectrum, reducing blue light.
2. Adjust Color Filters: For further customization, navigate to Settings > Accessibility > Display & Text Size > Color Filters. Turning on "Color Filters" and selecting options like "Color Tint" can help tweak the balance of your display even more.
3. Lower Screen Brightness: Reducing the overall brightness also helps to minimize blue light. You can easily adjust this in the Control Center or under Settings > Display & Brightness.
4. Consider Dark Mode: Activating Dark Mode can make your screen more comfortable for nighttime viewing. You can turn it on via Settings > Display & Brightness and select "Dark."

As a designer, I always consider how lighting—both natural and digital—shapes our environments. Just as a well-designed lighting plan in a living space promotes well-being, using these iPhone features improves digital comfort and health. When planning your home's visual environment, tools like a AI Interior Design platform allow you to experiment with lighting schemes, ensuring your physical spaces are just as kind to your eyes as your digital devices.

Tips 1:

Try automating Night Shift so it turns on at sunset and off at sunrise. This syncs your device’s display more naturally with your body’s circadian rhythm, minimizing disruption to your sleep patterns.
