- PrivacyGuard is a Lenovo computer software that secures your computer screen from prying eyes.
- It blocks the view of a person either peeping from the sides or directly over your shoulder.
- PrivacyGuard uses angled light technology to reduce your screen visibility from either side.
- It also includes an Open Glance App that detects and warns you of someone peeking over your shoulder.
- Open Glance works through the laptop camera.
- PrivacyGuard is enabled and disabled using the fn + d keys on your keyboard.
- The PrivacyGuard feature is, however, limited to some Lenovo computer models.
