Just go to Settings > General > Accessibility > Zoom > Zoom Filter and click on Low Light. Go back to the Zoom page and turn the slider on for Zoom. If your screen zooms in, just double-tap on any part of the screen with 3 fingers to bring it back to normal view.
To make it convenient at night to make your screen darker, you can create a shortcut by going to General > Accessibility > Accessibility Shortcut and click on Zoom. That way, every time you triple-click the home button, the screen brightness lowers. To go back to the normal state, just triple-click the home button again.
