Mobile phone camera lens protectors are thin, transparent plastic or glass covers that are placed over the surface of a mobile phone's camera lens. They are designed to protect the lens from scratches, dust and other debris, as well as providing additional protection against drops and falls. Mobile phone camera lens protectors are also designed to be ultra-thin, so they do not interfere with the camera's operation or image quality. Many mobile phone camera lens protectors are also designed to be fingerprint-resistant, so the lens stays clean and clear.
