The laptop privacy screen is very easy to install and remove. Simply attach the adhesive magnetic strips to the bezel of your display then align the notebook privacy filter with the strips. This black out privacy screen is also reversible. The matte side provides you with glare reduction and the glossy side of the privacy screen will provide you with increased clarity. In order to close and put your laptop to sleep the privacy screen must be removed. A protective folder is included so you can protect the privacy screen from damage when not in use. The privacy screen is also extremely easy to clean when removed from your laptop. The laptop privacy filter is a great investment if you want to protect your privacy. It is a convenient and cost-effective way to keep your classified information, intellectual property or any other important data you wish to keep protected. Whether travelling, working in the office or sitting in a busy coffee shop, you can have a peace of mind because you know your screen is protected with the 30+/- degree privacy viewing angle. The display privacy filter is designed to filter blue light (390nm~480 wavelength) that can cause digital eye strain and can disrupt sleeping patterns.
