Here's the problem: Your mobile device's screen normally emits a blue light that is good for daytime but may disturb your sleep at night. This is because blue light stimulates your brain and lurks that it is time, which can keep you awake if you use your device before going to bed.
Don't despair. You can get around the blue light problem if you are using an iOS, Android or Windows 10 device. On an iPhone or iPad you can use a function called Night Shift to change the color temperature of your screen to one that is less stimulating. Some Android devices offer a built-in Blue Light feature; otherwise you can turn to a variety of Blue Light apps. And with Windows 10, you can use a Night Shift function to move the color temperature. Let's see how it works on all three platforms.
iPhone or iPad
On your iPhone or iPad, go to Settings> Display & Brightness . On the Display & Brightness screen, tap the Night shift setting. This function changes the screen temperature to a warmer color and then filters out the blue light.
The night shift screen offers some options that can help you control when the screen changes colors and what colors to use. Press the Scheduled button.
Then tap the field that shows From and To times. Here you can set a start time and an end time for night shift. For example, you can set it to activate an hour before you normally go and shut it down and turn it off when you usually wake up.
You can also set the Night Shift to go to action especially from Sunset to Sunrise. If you do not see this option, return to the main setup screen. Press Privacy> Location Services . Scroll to the bottom of the Location Services screen and point to System Services. Turn on the time zone setting option. Return to the Night shift settings screen and press scheduled times. Now you see the option for sunset to sunrise.
Return to the main Night Shift screen. Press the setting to manually activate until tomorrow. The blue screen filter comes into effect and continues until the next day begins.
Finally, you can control the color temperature of Night Shift by moving the slider to more warm or less warm. Warmer settings are best if you want a good night's sleep, but you want to find a balance so that the screen is pleasing to see. Play around with this setting until you find the right temperature for you.
You can also enable Night Shift mode from the Control Center on your iPhone or iPad. To activate the Control Center, swipe your finger from the top at the bottom of the screen or from the bottom right right depending on the device. Press the Brightness control and then press the Night shift button.
Some Android devices have built-in blue light filters, which can be enabled or disabled from the drop-down menu. But as with many Android features, the availability of your specific device and version of Android depends.
To search for this feature on your Android phone or table, go to Settings> Display . Look for an alternative for Night Light or Blue Light filter. If you find it, press it to turn on the filter.
With some Android devices and versions, you can also schedule the Night Light feature and adjust the temperature as you can in IOS. If so, press the Schedule option and set the start and end times or select Sunset to Sunrise if available.
