With a screen protector, you protect the screen of your smartphone. Place a screen protector over your touchscreen and your screen will remain free from scratches. You can easily put your device in your pocket along with your keys. In addition, you can choose a glass or plastic screen protector. A glass screen protector feels like your own screen and offers protection against scratches. Plastic offers less protection, but the protective film is thinner and less noticeable. Go for a protective glass with a blue light filter if you suffer from tired eyes. A screen protector with privacy filter ensures that nobody can peek at your screen. Do you have a phone case? A case-friendly screen protector doesn't extend to the edges, so that your case still fits well around your device.
