No matter your reason, if you want to hide what's on your computer screen from prying eyes, there are plenty of ways to do it. You can get a privacy filter, install a panic button for your browser, or just develop super fast reflexes. But all it takes is the right angle or a too-slow reaction to blow your cover.
Want a foolproof way to make sure you are the only one who can see what's on your screen? Brusspup has just the fix for you.
He built an "Amazing Secret Monitor" by stripping the polarized layer off an old LCD screen and adding a layer to a pair of glasses. This way, what's on the monitor can only be seen by the person wearing the polarized glasses.
It's pretty easy to do and only requires basic tools like scissors and an X-Acto knife. You can order the polarized filter online and just use an old LCD monitor you have lying around.
If you don't have one you never use, your best bet is to grab one from the thrift store (if it's not clear yet, you'll be destroying the monitor).
The entire process shouldn't take more than 30 minutes. Take a look at the video to see how it's done.
