Face shields are clear plastic barriers that cover the front of the face, providing protection from splashes, droplets, and other potential hazards. They are often used in settings like hospitals, laboratories, and during certain activities where face protection is needed. Unlike masks, which cover the mouth and nose, face shields offer a wider field of vision and can be more comfortable for extended wear. These protective devices have gained popularity during health crises, such as the COVID-19 pandemic, as they can be worn alongside masks for added safety. Face shields are easy to clean and reusable, making them a practical choice for many people, including healthcare workers and teachers.
