Most privacy screen protectors use a form of micro louver technology that allows light from the display to pass through only at certain angles. Essentially how Venetian window blinds work, but at a microscopic scale. The filter layer is set to a narrow front angle, usually 60 or 90 degrees, and anyone looking at your screen from beyond that viewing angle won’t see anything.
There are quite a few brands that make privacy screen protectors. There are some things you should know before buying one though.
The most obvious advantage of using a privacy screen protector is in the name — privacy. Knowing that any sensitive information is safe from the prying gaze of bystanders is a big positive.
It isn’t just about privacy in public areas either. If a spouse, partner, or roommate gets annoyed at the fact that you are on your phone all night, a privacy screen protector helps here as well. It guarantees that they aren’t disturbed by the light from your phone, while you can continue to enjoy it without any issues.
