A laptop privacy screen can help you to keep others from seeing what you are up to on your laptop. Typically these screens give you a complete view of your laptop screen itself from the front but are blurred at the sides to keep people from peeking over their shoulder and seeing what you are doing. These can be very useful for those who are working in high security positions or simply for people who do not like others looking at their work. In some cases you may also get laptop privacy screens with glare protection to protect your own vision while you are working.
