LENSUN UV Curing HD Privacy Protector is a phone protector that protects your phone’s privacy and has Impact-Proof protection. When the protector finishes vacuum laminating in the UV vacuum lamination machine, its surface touches smooth like glass. Make them extremely durable and scratch-resistant and has HD & crystal viewing so a good privacy screen protector works by only allowing the screen to be visible at a 30-45 degree angle. Anyone further out will just see a dark screen. No cracked edges that hurt hands.
