If you’re browsing the internet right now (and you are), then odds are good anyone who walks into the room will be doing some over the shoulder peeking at your computer screen. It happens. Whether it's roommates, family members or someone else in the office, it’s easy for someone to make even your most work safe reading material seem forbidden. There’s only so much that can be done by tilting the screen at an angle or frantically covering it with your hands. For the crafty, however, there’s a cool solution that will fix the problem and employ some magic glasses.

This mod turns computer screens into something only the owner can see. The key is having an LCD monitor or digging up an old one. By removing the polarized film from the screen, the screen itself becomes a blank canvas. The film can then be molded to fit in the lenses of any old pair of glasses. When worn, the user can see what would normally be on screen through the glasses, while the display continues to look blank to anyone else.

 

 

 

Creating the privacy screen does take a little work. Gently taking apart the monitor and finding the polarized film takes a little effort. The process, however, is simple and clear. The glasses don’t even need to be high quality--a simple free pair from a 3D movie will suffice. The entire set of instructions is available at Instructables for the curious.
