Personal protective equipment and methods
Improved personal protective equipment facial wear including, in one embodiment, an at least partly adhesive mask, and one or more adhesive eye shields. In one implementation, the mask avoids significant contact with the delicate periorbital skin of the wearer, yet provides a substantially airtight seal so as to preclude moisture vapor transfer and “fogging” of eyeware or instruments. In another implementation, adherence of the eye shield is at least partially overlapping with the mask and creates an at least partial seal around a perimeter of the eye shield. Further, an at least partial seal is formed around a perimeter of the mask. The mask and eye shield additionally prevent nasal air flow obstruction, and address the problem of skin irritation and attachment during normal facial expression and movement of the wearer.

pressing on the at least one removable backing strip so as to cause adherence of the lower portion of the adhesive portion to the upper portion of the air-permeable portion;
placing the mask over the at least portion of the face while pressing on the at least one removable backing strip so as to cause adherence of the upper portion of the adhesive portion to the skin; and
after the adherence of the adhesive portion to the skin, peeling off the at least one removable backing strip from the outward-facing front side of the adhesive strip.
11 . The method of claim 10 , wherein the at least one removable backing strip comprises first and second removable backing strips respectively covering left and right sides of the outward-facing front side of the adhesive strip.
12 . The method of claim 11 , wherein the peeling off of the at least one removable backing strip comprises removing both the first and second removable backing strips by peeling away at least one respective edge of each of the first and second removable backing strips.
13 . The method of claim 10 , wherein the at least one removable backing strip imparts a degree of rigidity to the adhesive strip so as to enhance the adherence of the adhesive portion to the skin.
14 . The method of claim 10 , wherein:
the adherence of the upper portion of the adhesive portion to the skin forms a moisture vapor seal between the adhesive portion and the skin of the wearer so as to limit fogging of optical apparatus used by the wearer while wearing the mask; and
