Correct answer: A — To shield the eyes, nose and mouth from procedural splashes and aerosols
**A is correct.** A visor is facial personal protective equipment: it provides a barrier against aerosols and splashes that may contaminate the operator’s eyes and facial mucous membranes (nose and mouth). SDCEP lists masks, visors and face shields as protection from aerosols in dental practice. **B** is incorrect because illumination is provided by the dental operating light. **C** describes magnification provided by loupes or an operating microscope. **D** describes respiratory protective equipment such as a properly fitted filtering facepiece respirator; a visor does not filter inspired air. **E** is incorrect because the visor is principally worn to protect the dental professional; patient eye protection may be indicated separately.
