Abstract:  Coronaviruses and influenza viruses are primarily transmitted through respiratory droplets and direct contact. However, more and more studies have shown that these viruses may also enter the human body through the conjunctiva, causing ocular symptoms such as conjunctivitis and further spreading to the respiratory system. Coronaviruses and influenza viruses can invade the human body by specifically binding to different types of receptors on the surface of human tissue cells. These viruses can also mutate, leading to changes in their binding sites and transmission routes. It is suggested that medical staff wear goggles or face masks, and maintain good hygiene habits in daily life to reduce the risk of virus transmission through the eyes.
