You can protect your screen against scratches and stains with an iPhone 11 screen protector. A glass screen protector feels like your own screen and also retains the pressure sensitivity. You stick the glass plate over your own screen. Some screen protectors have additional functions. Choose an iPhone 11 screen protector with privacy filter if you don't like prying eyes. The screen will appear black when you look at it from the side. You only see your screen when you're right in front of it. Do you often suffer from tired eyes? Choose an iPhone screen protector with a blue light filter. This filter blocks the blue light, but doesn't make your screen yellow, like the night mode on your device does. You can easily combine the screen protection with a cover.
