Turning off blue light on your iPhone 15 is a piece of cake. All you need to do is dive into your settings, find the display and brightness section, and adjust the Night Shift feature to your liking. This is a great way to reduce eye strain and improve your sleep quality by limiting your exposure to blue light, especially at night.

Step by Step Tutorial: Turning Off Blue Light on iPhone 15

Before we get into the nitty-gritty, it’s important to understand that reducing blue light on your iPhone 15 can help minimize eye fatigue and make it easier to wind down at the end of the day. Let’s get started!

Step 1: Open the Settings App

The Settings app is where all the magic happens. It’s your control center for all things iPhone, and it’s where you’ll find the options to adjust your display settings.

Step 2: Go to Display & Brightness

Scroll down and select the “Display & Brightness” option from the list.

Once you’re in the Display & Brightness section, you’ll have access to all the settings that affect your screen, including brightness, text size, and, of course, Night Shift.
