About

To compare the prevalence of dry eye symptoms and to investigate the association of the risk factors with the dry eye symptomatology among university students in the epidemic and non-epidemic areas of China under the COVID-zero strategy.

Full description

As the COVID-19 outbreak at the end of 2019 spread around the world, the World Health Organization declared it a public health emergency of international concern on 30th January, and a global pandemic on 1st March. In addition to the threat of coronavirus itself, anti-epidemic measures such as wearing masks, maintaining social distance, prohibiting group gathering, blockade, isolation, curfew, closure, working at home, online learning, etc., have also greatly changed people's daily life dynamics. Unlike the previous regional blockade (city-wide) suspension of school and work, China has shifted to dynamic prevention and control in April 2020, and the basic life and activities in the epidemic area are not restricted. This study aims to compare the prevalence of dry eye symptoms and to investigate the association of the risk factors with dry eye symptoms among college students in the epidemic and non-epidemic areas of China under the dynamic COVID-zero strategy.
