The COVID-19 virus is a subgroup of zoonotic viruses. The most terrible problem started when the number of infected patients with acute respiratory syndrome quickly spread around the world, which made it as a global pandemic. This novel virus could transmitted from person to person via infected droplet entering the respiratory system whether nasal or oral cavity. Close contact less than 6 feet, with infected individuals particularly in crowded environments has characterized the rapid spread of the infection. Clinical signs of the COVID-19 infection have mentioned the presence of some ocular findings such as conjunctival congestion, conjunctivitis and even corneal injury associated with the classical COVID-19 infection. In this review, we showed that different viruses could be and transmitted by tear fluid which encourage us to search regarding to this potential in COVID-19 virus.
