6.iOS Night Mode Filters Blue Light to Improve Your Sleep
iOS night mode feature really helps to reduce the blue light effect on your eyes so that you will get a good sleep in the night.
You don’t have to use any other app on the iPhone or iPad to reduce the blue light effect. Since iOS 9.3, Apple has introduced iOS night mode features. Just with a single touch, you can enable or disable these features. It is a great feature that improves your sleep. According to the Apple Support topic, Nightshift mode adjusts the color of your display. It will shift your display colors to the warmer end of the color spectrum so that it will make it easier on your eyes.
How to enable iOS Night Mode
All iOS devices don’t have these features. iOS 9.3 and above will have Nightshift features. You must upgrade your iOS to at least iOS 9.3 or above. iPhone 5S and the above model can only support this feature. If you have lower-end mobile, you better use the f.lux app. iOS supports automatic or manual enabling of this feature. Let us see two methods.
Go to Settings -> Display & Brightness.Touch on Night Shift option. I would also recommend you to enable the Auto brightness option which helps a lot to your eyes. Though the Auto-Brightness option has an effect on your battery, it will help your eyes.
After clicking on the Night Shift option, you will see the below screen. Just toggle the Scheduled option to enable iOS night shift mode.
At bottom, you will see the option to adjust the Warm level. You can keep it at the center or reduce it. When you reduce, your device will emit less warm lighting. If you slide towards the right side, it will improve the warm level of your device colors. It is better to keep it at the center.
You can see another option to schedule the night shift. Just click on From To option. You will see two options. You can use a custom schedule to enable or disable the night shift at predefined intervals. I recommend you to use the first option which is Sunset to Sunrise. When you use this option, your device will use your device’s location service to enable the night shift at sunset. It will automatically disable the Nightshift at sunrise.

It will turn on Night shift mode immediately. Just touch one more time to disable.
Now it’s time to wrap up things, Try f.lux first if you aren’t happy then choose Irish mini or Irish premium(10% Discounted Link) for the best features.
If you still feel the problem in your eyes, I highly recommend visiting an eye specialist for professional analysis and treatment. Don’t treat your eyes lightly because, without eyes, it will be dark forever.
