Imagine looking through a fence. If you stand right in front of it, you can see through just fine. But if you stand to the side, all you see is the fence. A privacy screen works just like that! When you look at your phone straight on, everything looks normal. But if someone next to you tries to peek, all they see is a dark screen. Pretty cool, right?

Regular glass breaks pretty easily if you drop it. Tempered glass is special glass that has been heated up really hot and then cooled down super fast, which makes it much, much stronger. Our tempered glass goes on top of your phone screen to protect it.

Your phone screen makes a kind of light called blue light. You cannot see it, but your eyes can feel it after a while, kind of like how your eyes get tired after reading for a long time. Too much blue light, especially at night, can also make it harder to fall asleep. A blue light screen protector is like sunglasses for your phone. It blocks the tiring light so your eyes feel better and you can sleep easier at night.
