The eye shield presented to you is one of the shields used to protect against the entry of any microbes into the eye. These shields have a protruding design. These protruding structures are made of compressed plastic, and they have holes in them. These holes are also used for air exchange. The reason for the protrusion of these structures is their ability to protect and cover any bandages underneath these products. These structures are completely scratch-resistant and impact-resistant. Plastic eye shields are used after eye surgeries or LASIK procedures, etc., to protect the bandage and the eye.
