MahadealzDesign Edge To Edge Screen Guard for Apple iPhone X, Apple iPhone XS Membrane  (Pack of 1)

This Anti spying Screen guard protects your screen from a spy views. A privacy screen protector serves double duty as a screen guard to keep your display scratch-free while also keeping your data safe from prying eyes. Like a regular screen guard, these can be of the PET film or tempered glass variety. But, it has an additional anti-spy layer that limits the viewing angle of your display. The viewing angle has to be narrow enough so that people standing or sitting next to you are out of range. If a viewing angle is too wide, it defeats the purpose of having a privacy screen protector. On the flip side, if it’s too narrow, it may impact your own viewing experience. You’ll have to face the screen head-on to make sure that you can see the screen properly. With most privacy screen protectors, the available viewing angle is usually 60 or 90 degrees.
