What is a Computer Privacy Screen?

A computer privacy screen is a fairly recently introduced technology. Earlier computer screens were developed to purely protect users from the reflected lights off computer monitors and reduce eye strain. Privacy screens are one step ahead, compared to the old anti-glare screens.

Not only do they provide protection for the eyes from reflected glares, but they completely block out the screen view for anybody watching the screen at an angle. Only the person sitting in front, at a 90 degree viewing angle, gets a clear view, while all the views from other angles are blocked. They can be easily hooked on to the computer screen using clips.

While I am not exactly sure about how does a computer privacy screen work, my guess is that the screen is polarized with a multilayer coating to prevent any view from slant angles. These screens also inculcate all the features of anti-glare screens to prevent any light that's reflected from the background to stress the user's eyes. They come in a variety of sizes and are designed to fit CRT, LCD and LED monitors of desktop and laptop computers. In fact, these screens are also available for use with cell phones. Depending on the size, quality and brand, privacy screens can cost anywhere between $20 to more than $300.
