Abstract

The present work aims to select the proper materials of goggles to provide protection from newly COVID-19 viruses. Electrostatic charges (ESC) generated on the surface of polymeric materials during contact and separation as well as sliding can be used to repel the negatively charged viruses like COVID-19 out of the eyes so that the goggles can protect the eyes from infection risk. ESC generated on the surface of the medical safety goggles is measured to determine their sign and magnitude and investigate their performance in protection of the wearer from viruses. Two type of medical safety goggles were used the first was polymethyl methacrylate (PMMA), while the second was polyvinyl chloride (PVC). They were rubbed by different materials.
 
It was found that PMMA goggles rubbed by different materials generated positive ESC so that the application of such material should be limited. It is recommended that, the material of goggles should be in the lower part of the triboelectric series that includes PE, PP and PVC, because they gain strong negative ESC able to repel the viruses away of the wearer. Besides, the negative ESC generated on the surface of goggle can ionize the air in the front of the goggle to be negatively charged and offer region of negative ESC and electric field.
