How do privacy screen protectors work?

Visual hacking has been around for years, and today our phones contain much more personal information and access to much more information as well. People are also using their mobile devices everywhere, leaving the content of their screens exposed. We are talking logins, payroll information and countless other sensitive data about you, your friends and family, and the company you work for. You need to consider if you are okay with this. Or if you should shield this content from visual hackers. How, you ask? With a privacy screen protector for your device.


A privacy screen protector shields the content of your screen from everyone except you.This means, that you can use your phone or tablet everywhere you go without having to worry about visual hackers.

See your Snaps, FaceTime with your friends, or go through important work documents on the metro - your by-sitters won't be able to see what you are doing. And you won't be guilty of sharing confidential business information unintended.  In short: You don't have to worry about curious eyes when using your phone or tablet.


Privacy screen protectors have a special filter (the privacy filter) that allows light to pass through from certain angles. You can compare screen privacy filters with traditional window blinds. Except, the blinds (the filter in this case) are preset to a narrow front angle, letting you see everything clearly, while people next to you are unable to see the content of your screen. All they see is a darkened/blackened screen. In other words: You get to choose what the world sees.

Privacy filters are an easy way of keeping strangers from seeing what it is on your phone or tablet. And they are available for laptops meaning you can work on your computer everywhere without having to think about anything but working. This is especially useful if you are handling essential documents, emails e.g., working on public transportation. Or just want to browse your device privately.




Now you know that PanzerGlass Privacy screen protectors effectively "black out" privacy from side views outside the 60-degree viewing angle while providing you with an excellent viewing experience. But besides effectively shielding the content of your screen, some privacy screen protectors have additional features. For PanzerGlass Privacy this includes an anti-glare coating as well as blue light reduction.


You have most likely tried it yourself: The sun is out and it is impossible to see anything on your screen! With an anti-glare coating, light reflections are reduced, letting you see the content of your screen more clearly. This means, that you can use your laptop outside when working, something that is practically impossible without an anti-glare coating. Please note, that the screen will be slightly darker when fitted with a PanzerGlass Privacy screen protector (due to the privacy filter).


Some privacy screen protectors, like PanzerGlass Privacy, also feature blue light reduction. Blue light has been proven to affect your sleep negatively and disrupt your circadian rhythm. This occurs because blue light inhibits the release of sleep hormones, causing us to become more awake. That's why scientists recommend, that exposure to blue light at night is decreased. And this is where privacy screen protectors come in handy. They can reduce the amount of blue light emitted by your device, which decreases the effects of the blue light. You will still get exposed to it, but the effects will be reduced. Without knowing exactly how much the effects are reduced, it is fair to say, that using your phone or tablet at night won't disrupt your sleep as much when using a privacy screen protector.


Besides the privacy filter, privacy screen protectors usually feature the same benefits as a regular screen protector. Of course, this is the case for PanzerGlass Privacy. Our privacy screen protectors have the same core features as our regular screen protectors + the privacy filter, blue light reduction and anti-glare coating. They are shock and scratch resistant, preserve 100% touch sensitivity and have an oleophobic coating to reduce fingerprint and smudge-marks.
