What is a Privacy Screen Protector and How Does It Work

Privacy is a crucial thing, especially when it comes to our personal space and properties. Numerous apps help provide privacy and hide from others what we do on our phones, laptops and other devices. But what other people miss is a physical privacy protector in the form of manufactured screens.

Understanding Privacy Screen Protectors

A privacy screen protector is a manufactured screen protector that guards your privacy against those who want to take a peek into your screen. They serve a dual purpose: to protect your privacy and prevent scratches and bumps on your phone screen.

Privacy screen protectors are helpful when you’re travelling and publicly commuting. When you’re on your phone in a bus or a train, a regular screen protector allows people on your sides to view your screen.

On the other hand, a privacy screen protector can keep private and sensitive information on your screen to yourself only. Onlookers cannot peep into your phone and observe what you’re doing. This way, you can prevent visual hacking.

How Does It Work?

Some privacy screen protectors darken your screen, which keeps onlookers away but can be disadvantageous to you. These cheap privacy screen protectors are not what you want to use.

A good screen protector uses polarisation, a technology that blocks light at particular angles. That is the same technology behind sunglasses. With that said, this type of screen protector limits the screen visibility at a 30- to a 45-degree angle. So those by your sides can only see that your phone has a dark screen.

What Makes a Good Privacy Screen Protector?

You should be able to pick the best privacy screen protector on the market. So here are some considerations to factor:

  1. Privacy Technology: You can do better with a polarised screen protector that shows your screen at a limited angle and perhaps only limited to you. Cheaper privacy screen protectors just darken screens, which isn’t helpful to you.
  1. Angle: You can choose between privacy screen protectors that show your screen at a 30- or a 45-degree angle. Either way, your screen is accessible to you by looking at it directly and protected against onlookers on both sides of the screen.
  1. Material: Two of the most common privacy screen protectors are made from glass and film. The latter is a good fit for most phones, especially those with curved screens. On the other hand, tempered glass is a better screen protector for scratches and breakage and when curving isn’t factored.
  1. Two-Way or Four-Way: As angles protect your screen privacy against onlookers from both sides, you can choose what to show to other people by tilting your phone to either side. However, there is the matter of who can see it from above you. If you want to limit the accessibility of your screen from anyone above you, get a four-way screen instead of a two-way one.


Protect your privacy against onlookers that might be trying to phish for private and sensitive information like passwords, bank details, emails and more. Even your messages should be accessible to you alone, and while no one can be guaranteed privacy in public places and transportation, at least a privacy screen protector can help.
