Many professions involve people wearing face shields to protect themselves or the people they are serving. In the foodservice industry, they are worn to prevent workers from contaminating food with bacteria or viruses. On the other hand, on construction sites, those involved in welding or grinding will sport them to protect their faces from flying sparks, dust, and debris. People in healthcare, grocery stores, salons, etc. wear them while carrying out certain tasks, and nowadays, due to COVID–19, people regularly put on face shields while going out too.
