Face shields are meant to provide an extra layer of protection. In medical settings, face shields are used when the chances of hazardous substances or bodily fluids getting into the eyes, nose, and mouth are pretty high. Experts recommend using disposable face shields for better prevention. However, if you decide to purchase face shields for personal use, wear them with a face mask to reduce the risk of exposure to COVID-19. Also, clean it after every use. To clean a face shield use warm, soapy water first to get surface contaminants off. Carefully wipe the face shield using antibacterial wipes and clean with a towel and water or alcohol-based disinfectant to remove any residue.
