Abstract：During the coronavirus disease 2019 (COVID-19) epidemic period, medical staff do all kinds of effective protection in order to avoid virus infection. Masks, protective clothing and goggles are essential for preventing viral infections. It was found that most goggles worn by the medical staff could fog up quickly. This situation will block vision, increase risks and interfere with clinical work; nurses cannot perform duties effectively, doctors cannot diagnose and treat accurately. Emergency rescue of patients is delayed, and improper protection even leads to cross infection in the hospital. After a literature review and results of clinical practice, combined with professional knowledge, we propose how to choose protective goggles correctly, and seven methods to keep goggles clear of fog. This study is expected to be helpful to medical workers in the prevention and control of COVID-19.
