1、Anti Prying and Enhanced Security: Computer screen protector is designed for using in public areas with the 60 degree full view angle to protect your personal confidentiality. No need to worry about being peeped on your computer screen as the computer filter makes the screen appearing dark when looking at it from an angle (the angle is about 30 degree to 60 degree), but brighter when looking directly at it. 2、Hanging Design: Different with the adhesive anti peep screen for computer display, hanging computer screen shield is to hang it directly on the computer to finish the installation and take it off when not in use without worrying about leaving traces of adhesive on the computer display. Adopted with PC composite material, it is scratch proof. 3、Eye Care and Harmful Light Restrain: Hanging screen protector with superior visual clarity to reduce eye strain and minimize the potentially harmful effects on your eyesight. Say goodbye to a headache and overshadowing images even though long time use on computer. 4、Dust Proof: Protect your screen from scratches and dirt, prolonging your screen's lifespan. Our computer screen protector, serving as an outer layer for the screen, prevents dust from getting in. It comes with a soft fine fiber cleaning cloth. 5、Practical Accessory: It is suitable for various places where you need to protect screen confidentiality. If you purchase a new computer display, it can even be disassembled and reused.
