PC privacy screen filters keep confidential data safe from wandering eyes. String passwords and encryption software help you keep your private work data private.

But such tools can’t stop someone from peering at your screen from over your shoulder or snapping a picture of what you are working on.

This is called visual hacking, and it is a serious security threat that businesses shouldn’t ignore anymore. Fortunately, the issue can be easily fixed with privacy filters that adhere to a machine’s display.

These filters severely restrict the viewing angle in such a way that only someone who is sitting in front of the screen can see what’s on it. Anyone who tries to sneak a peek from the sides or the top will only get to see a blank screen.


Here’s why you should use privacy screens

In addition to protection your documents from being viewed by prying eyes, a privacy filter can also help eliminate excessive glare from your computer screen.

Did you know that glare causes all types of conditions ranging from chronic headaches to Presbyopia which is actually the weakening of your eye muscles?

When you are able to eliminate glare from your computer screen, you can work much longer house without feeling tired or getting a headache.

People who have complained of headaches at the end of every day found a significant improvement in their condition as soon as they installed an anti-glare filter on their computer screen.

How does privacy filters work?

Privacy screens are quite low-tech, and they consist of only a polarized plastic sheet. Polarization works as an optical filter that blocks out light from particular angles.

This is the same technology that is used for polarized sunglasses and some types of camera lenses.

What to look for in a high-quality privacy filter?

Clarity of image

Privacy filters have the tendency of blocking some light from the PC’s screens making them appear dimmer. Dimming can be offset by turning out a screen’s brightness, on the other hand.

Application

The way that you apply the filter to the screen varies from model to model, and you should look for a filter that is easily applied and removed over and over again.

The best filters adhere to using reusable micro-suction strips that will not leave any sticky residue.

Matte finish

Some privacy filters can give glossy screens a matte look, and this will help ward off distraction reflections, but it can also make the display look pretty dull.

Some filters are reversible, and they let you choose between a matte or a glossy side before you apply them.

Colors

Privacy filters come in more colors, and the basic ones will look black once you apply them when they are viewed from an angle. You can also get filters that give off a gold sheen when they are viewed from the side.

Such gold filters will be a bit more expensive because they will not dim your screen so much but on the other hand, they also tend to be more reflective than black ones.

This means that they are not that good for people who are working outdoors. To make your task easier, we selected 4 of the best privacy filters for PC using the criteria listed above.
