So far, the number of people infected in China has climbed to more than 70 000. Of them, at least 3019 healthcare workers have been infected. However, the specific causes of infection among healthcare workers in hospital environments are unclear. It has been confirmed that COVID‐19 is mainly transmitted through both respiratory droplets and direct contact. Aerosols are another possible transmission route requiring attention. In February 2020, a report in The Lancet raised the issue that ocular surfaces may be a potential target for SARS‐CoV‐2 invasion (Lu et al. 2020). However, two recent studies do not fully support this assumption (Li et al. 2020; Zhou et al. 2020, unpublished paper). The reason is that although a small number of COVID‐19 patients have conjunctivitis, not all of them show positive test of SARS‐CoV‐2 nucleic acid in conjunctival sac swabs. In addition, some patients did not have conjunctivitis despite positive test results for the SARS‐CoV‐2 nucleic acid in their conjunctiva sac swabs (Dr. Yanping Song from Wuhan City, China, the outbreak area in China, unpublished paper). Interestingly, the medical history of the clinical physicians with COVID‐19 revealed that neither of them used eye goggles when examining (physician 1) and intubating infected patients (a high‐risk procedure to produce aerosol) (physician 2)."}
