Their effectiveness is dependent on the quality of the visor, structure and fixation system. They should be used as adjuvants for other personal protective equipment (PPE). Their isolated use is not recommended because of the fragilities of peripheral. faceSealing is important, especially during the COVID-19 epidemic period.
