Nowadays, many people use their phones on buses, subways, cafes, and offices. Without protection, strangers can easily glance at your screen and see your messages, bank information, and personal photos. This makes privacy a big problem for most smartphone users.
A privacy screen protector is one of the easiest and most affordable ways to stop side peeking. In this guide, we will explain how it works, its advantages and disadvantages, and how to choose the best privacy screen protector for your iPhone 15.
What Is a Privacy Screen Protector?
A privacy screen protector is a special tempered film that limits the viewing angle of your phone screen. When you look directly at the screen, the display is clear and normal. But when people look from the side, the screen turns dark and cannot be seen.
Most privacy films support 28° anti-spy viewing angle, which perfectly prevents peeking in public places.
How Does an Anti-Spy Screen Protector Work?
It uses a micro-louver optical structure, just like window blinds. Light can only pass through in the front direction, and side light is blocked.
This technology does not affect daily use, but it greatly protects your chat records, payment information, and private photos from being seen by others.
