New York University is among the many academic, private and public institutions doing what it can to address the need for personal protective equipment (PPE) among healthcare workers across the world. The school worked quickly to develop an open-source face-shield design, and is now offering that design freely to any and all in order to help scale manufacturing to meet needs.

Face shields are a key piece of equipment for front-line healthcare workers operating in close contact with COVID-19 patients. They’re essentially plastic, transparent masks that extend fully to cover a wearer’s face. These are to be used in tandem with N95 and surgical masks, and can protect a healthcare professional from exposure to droplets containing the virus expelled by patients when they cough or sneeze.
