Looking at your phone at night is a bad idea. The bight blue light emitted by the screen can make it more difficult to fall asleep and mess with your sleep cycle, which could lead to a whole host of health problems.

But there's some good news on this front: The next version of Apple's operating system for the iPhone is going to come with a new feature called Night Shift, which will "warm" your display as the sun goes down and it gets dark, decreasing the blue light emitted by the screen.

But there's some bad news, too — Night Shift isn't available yet. (It'll probably be released next month.)
But don't worry! There's a way to dim the iPhone's screen even further than the Settings allow. I first learned about it about dimming my iPhone last year when I came across a guide on Medium written by Justin Searls, a programmer, and I use it pretty much every day.
It involves a few steps, but it's easy to do and will completely change how you use your phone at night.

First, go to the Accessibility settings in your iPhone's Settings.
Settings —> General —> Accessibility
Then, tap on Zoom and turn it on.

Next, tap on the screen three times using three fingers.
This will bring up a menu. Tap on "Choose Filter" and select "Low Light."
Make sure you're not zoomed in at all by toggling the magnifying glass all the way to the left.
Then, tap anywhere outside of the pop-up to go back to the screen.
Make sure that "Zoom Region" is set to "Full Screen Zoom."

Now, go back to the Accessibility settings and scroll all the way to the bottom and tap on "Accessibility Shortcut."
In the Accessibility Shortcut menu, tap Zoom. This will set your iPhone to dim the screen when you triple click the Home button.

Now, making the screen of your iPhone ultra dim is as easy as triple pressing your home button.
To get the brightness back to normal, press the button three more time.
