With an iPhone 12 screen protector, the screen of your iPhone stays as new for as long as possible. The iPhone 12 screen protectors are made for the 6.1-inch Super Retina display and fit well around the device. A glass screen protector protects the screen of your iPhone 12 better than a plastic screen protector. Some screen protectors have extra functions. For example, a privacy screen protector prevents peeping, because you can only see the screen when you're right in front of it. A screen protector with a blue light filter prevents strained eyes.
