Using Night Shift on Your iPhone
Night Shift is a built-in feature on iOS devices that allows you to filter out some of the blue light emitted by your iPhone’s screen. To activate Night Shift, go to “Settings,” navigate to “Display and Brightness,” and turn on Night Shift mode. You can choose to schedule Night Shift to automatically enable at a specific time or manually enable it. Night Shift changes the color output of your screen to a warmer, more amber hue, reducing the amount of blue light. This can help reduce eye strain and improve sleep quality.

Using a Red Color Filter on Your iPhone
If you want to further control blue light on your iPhone and promote better sleep, you can set up a red color filter. This feature can be accessed through the Accessibility settings on your iPhone. By applying a red overlay to your screen, the red color filter significantly reduces the amount of blue light emitted by your device.
To set up the red color filter, follow these steps:
- Go to Settings on your iPhone.
- Navigate to Accessibility.
- Select Display & Text Size.
- Activate the Color Filters option.
- Choose Color Tint.
- Set the intensity bar to maximum to apply a red overlay to your screen.
Once the red color filter is enabled, you’ll immediately notice a reduction in blue light. This can be particularly helpful when using your iPhone in low-light conditions or before bedtime, as it minimizes the impact on your sleep quality.
“The red color filter on my iPhone has made a significant difference in reducing eye strain and helping me sleep better at night. I no longer feel the same level of discomfort when using my phone in bed, and it’s been a game-changer for me.”
– Lisa, iPhone user
By utilizing the red color filter feature, you have greater control over the blue light emitted by your iPhone, ensuring a more comfortable viewing experience and promoting healthier sleep patterns.

If you want to make it even more convenient to switch on and off the red color filter on your iPhone, you can create a shortcut using the Accessibility settings. By setting up a shortcut, you can quickly enable or disable the red color mode with just a triple-click of the home button.
To create the shortcut, go to “Settings,” navigate to “Accessibility,” and select “Accessibility Shortcut.” From the options available, choose “Color Filters” as your shortcut option. Now, whenever you want to activate or deactivate the red color filter, simply triple-click the home button, and the change will take effect.
This shortcut eliminates the need to navigate through the settings menu every time you want to enable or disable the blue light filter on your iPhone. It’s a time-saving feature that provides quick and easy access to the red color mode, allowing you to protect your eyes from blue light exposure whenever you need.
Benefits of Using the Shortcut
- Convenient and easy access to the red color filter
- Quickly enable or disable the blue light filter with just a triple-click
- Saves time by eliminating the need to navigate through the settings menu
Other Methods to Reduce Blue Light
Besides using the blue light filter on your iPhone, there are other methods to reduce blue light exposure for better sleep. One effective method is to stop using your iPhone (or any electronic devices) at least one hour before bedtime. This allows your body’s natural melatonin levels to rise, promoting better sleep.
Additionally, you can invest in a pair of blue light glasses with orange lenses. These glasses block out blue light and can be worn while using your smartphone before bedtime. They are especially useful for those who can’t completely avoid electronic devices before sleep.
“By avoiding device use before bedtime, you give your brain a chance to wind down and get ready for sleep,” says Dr. Sarah Johnson, a sleep specialist. “The blue light emitted by devices like iPhones can interfere with the production of melatonin, the hormone that helps regulate sleep.”
- Stop using your iPhone at least one hour before bedtime
- Invest in blue light glasses to block out blue light
Studies on Blue Light and Sleep
Several studies have highlighted the negative effects of blue light on sleep. Research conducted at the University of Harvard found that exposure to blue light suppresses the production of melatonin, resulting in difficulty falling asleep and a decrease in sleep quality. Another study published in the Journal of Applied Toxicology found that blue light exposure at night can disrupt the circadian rhythm, leading to sleep disturbances and increased risk of chronic diseases.
| Study | Findings |
|---|---|
| University of Harvard | Blue light suppresses melatonin production, impacting sleep quality |
| Journal of Applied Toxicology | Blue light exposure at night disrupts the circadian rhythm and increases the risk of chronic diseases |
These findings highlight the importance of reducing blue light exposure, especially before bedtime, to ensure a good night’s sleep. By implementing methods such as limiting device use and wearing blue light glasses, you can protect your sleep and overall well-being.
Night Shift on Android Devices

Blue Light Filter Apps for Android Devices
If your Android device doesn’t have a built-in blue light filter or lacks certain features, you can use third-party apps to achieve the same result. Some popular blue light filter apps for Android include sFilter and Twilight. These apps allow you to manually turn on a blue light filter, schedule it to activate and deactivate at specific times, and adjust the color temperature according to your preferences.
