What Is Blue Light and Why Should You Care?
You’ve probably heard the term “blue light” before but what is it? It’s a type of light that comes from screens like your phone, tablet, laptop, and even LED bulbs.
It’s a type of visible light that keeps you alert and awake which is great when you’re trying to power through the workday or stay focused during a Zoom call. But at night? Not so great.
Your body has this hormone called melatonin which helps you relax and fall asleep. When you’re exposed to blue light late in the evening (say, scrolling in bed), it can trick your brain into thinking it’s still daytime.
In fact, Harvard Health notes that nighttime blue light exposure can throw off your sleep rhythm by blocking melatonin.
The Benefits of Using a Blue Light Filter on Your iPhone
Turning on a blue light filter on an iPhone has several helpful benefits:
- Reduces eye strain at night
- Helps your body prepare for sleep
- Makes screen brightness feel less harsh
- Improves comfort when reading or watching content in the dark
These changes may seem small, but they make a big difference over time.
How to Turn BlueLight Off on iPhone
Tired of your screen being too bright at night? Your iPhone has a setting called Night Shift that makes the screen warmer, so it’s easier on your eyes (and better for sleep).
Here’s how to turn it on
- Open the Settings app.
- Tap Display & Brightness
- Select Night Shift
- Choose one of the following:
- Tap Turn On Until Tomorrow to activate it now.
- Tap Scheduled and choose either Sunset to Sunrise or set custom times.
This built-in feature works as an iPhone blue light filter and takes less than 30 seconds to turn on.
How to Use the iPhone Blue Light Filter (Night Shift Explained)
Night Shift is Apple’s official feature that helps reduce blue light by adjusting your screen’s color temperature.
You can use it in two ways:
Manually: Turn it on or off whenever you need it.
Automatically: Set a custom schedule or let it run from sunset to sunrise.
To adjust the filter strength:
Go to Settings > Display & Brightness > Night Shift
Use the slider to choose how warm or cool your screen should appear.
The warmer the tone, the less blue light your eyes will absorb. This setting helps you wind down and avoid unnecessary screen strain before sleep.
Use Siri to Turn On Night Shift (Night Light iPhone Feature)
Want to make it even easier? You can use Siri to turn on Night Shift without touching your screen.
Just say:
“Hey Siri, turn on Night Shift”
This voice command works instantly and is perfect when your hands are full or you’re already in bed. It activates your night light iPhone setup without needing to open the Settings app.

Extra Tips to Stop Blue Light on iPhone
Night Shift is great on its own but there are a few bonus settings that can make your screen feel even easier on the eyes. It makes a big difference if you tend to scroll at night:
- True Tone: This adjusts your screen based on the lighting around you. Things look more natural and softer overall.
→ Find it under: Settings > Display & Brightness > True Tone
- Dark Mode: Swaps out bright backgrounds for darker ones. It is easier on the eyes and it looks pretty slick too.
→ Enable it in: Settings > Display & Brightness > Appearance
- Reduce White Point: If even the dimmest setting still feels too bright, this one tones down the intensity of whites on your screen.
→ Try: Settings > Accessibility > Display & Text Size > Reduce White Point
Night Shift Not Working? Here’s How to Fix It
If Night Shift isn’t working on your iPhone, don’t worry. It’s usually an easy fix. Here are some quick ways to troubleshoot it:
- Can’t find it in settings? Night Shift is available on iPhones running iOS 9.3 or later. Make sure your software is up to date.
- Not activating on schedule? Go to Settings > General > Date & Time and turn on Set Automatically. Scheduling depends on the correct time zone.
- Using Low Power Mode? Some background features like Night Shift may turn off to save battery.
- Still, having trouble? Restart your iPhone, or go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings to clear display glitches.
In most cases, one of these steps will get Night Shift working again in seconds so you can keep blocking blue light without interruption.
