These protective face visors are for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids.
This design is very lightweight and was the most comfortable visor we trailed.
The visors also work as a great way of making you aware of when you touch your face.
During the COVID19 crisis it would be sensible for those working in service areas to be equipped with these to further prevent the spread of the virus.
Visor can be rinsed with warm soapy water using a soft cloth or follow the recommended guidelines of your place of work.
