FIELDThe present invention relates to a face shield to protect the face and eyes of the wearer from various viruses, and more particularly, the invention is directed to a face shield from various viruses that includes a feature to position the face shield away from the face.
BACKGROUNDMedical and dental care professionals are exposed to infectious pathogens on a daily basis. With the spread of various viruses, such as COVID-19, and diseases, many that are deadly and presently incurable, the protection of these professionals has become more vital than ever. Many of the viruses and diseases come from nasal and oral emissions, blood, and other bodily fluids. Because the eyes, nose and mouth include regions of thin and penetrable membranes, the face is an area requiring appropriate protection from flying contaminants and particulates.
Several requirements must be met by a facial protection device of this type. It must be light weight and easily worn and removed. It must adequately shield the vital areas of the face yet not obstruct vision. It must provide ample ventilation as not to hamper breathing and to further avoid fogging and accumulation of moisture. In addition, it should be disposable for adequate and safe disposition of contaminants.
There is thus a need for a face shield which is capable of being comfortably worn which will protect the desired areas of the face and eyes.
