For the general public, if they are not hospitalized and do not come into contact with febrile patients, goggles are usually not required and a mask is sufficient for protection. However, goggles are required for protection in areas such as isolation wards (rooms), isolation wards (rooms) and isolation intensive care wards (rooms), as well as for medical workers performing operations such as collection of respiratory specimens, tracheal intubation, tracheotomy, non-invasive ventilation, and aspiration. Other than that, other areas and diagnostic operations in other areas can, in principle, temporarily dispense with the use of goggles. Content source: Dr. You Lai
